DIY rechargeable bicycle light making process.

The body of the bike light will be the body from the old head lamp.

And to charge this battery, I took the PDIF connector from the speakers. Other connectors such as micro USB can be used. I just didn’t have any more connectors.

The PDIF connector was large in size, and using a utility knife I cut off unnecessary parts.

Using a clerical knife, we strip the ends of the wires from the connector.

We solder the stripped wires to the battery, but at the same time observe the polarity, red. plus, and black. minus. If confused, charging can damage the battery.

Next, we take a board with soldered LEDs, an on / off button and a battery and solder them in series with wiring.

We take the wiring and clean the ends with a knife, and with the help of an electric soldering iron we cover the bare places with lead tin solder.

We solder the black wires to the minus of the battery.

Then we solder the same wiring to the power button.

We take another wire, also black, and solder them with an electric soldering iron to the button, but to other contacts.

Now we take the red wire and solder it to the positive terminal of the battery.

It remains to solder the LEDs to the electrical circuit.

We solder red and black wires to the board with LEDs. Be sure to observe the plus and minus wires.

We check our circuit for performance. As you can see, everything works for us.

Next, using a glue gun, insulate the bare contacts with hot melt glue.

Now this whole chain must be placed in the case.

We take the case and make a hole on it using an electric drill slightly larger than the diameter of the PDIF connector.

Glue the connector itself near this hole. To do this, we take a plastic case from a CD disc.

Using a marker, draw the next shape on it and cut it out along the contour using a clerical knife.

We glue it with a glue gun inside the lantern body as follows.

We place the chain inside the case. We glue the PDIF connector to the previously prepared place.

We glue the board with LEDs using a glue gun to the PDIF connector itself.

We place the battery and the power button in another place, and also fix them with hot melt glue.

We close this entire structure with a plastic part.

We also close the front part. To do this, take any transparent plastic material and cut a circle out of it.

Next, we take a plastic bottle from vitamins and cut its upper part.

On the sides, using a clerical knife, we make small indentations.

This flashlight can also be used as a head.

Now we need to attach this flashlight to the bike. To do this, we take a bicycle handlebar mount.

We make a recess on the mount and fix it on the flashlight.

We make a hole on both the lantern and the mount and fix them with a screw and nut.

Now you can attach the light to the handlebars and our bicycle light is ready.

We are starting to make a cable for charging a bicycle headlight. There are two types of connectors for this: USB connector and PDIF connector.

Next, we take the cable and clean its ends with a clerical knife.

Using an electric soldering iron, we solder the USB connector, PDIF connector and cable. Again, observe the polarity. In my case, the blue wire has a positive sign and the brown one. negative.

We close the cover of the USB connector, and apply the PDIF connector with hot glue and insulate with a heat-shrink tube.

That’s it, and your bike light charging cable is ready. Now you can charge the flashlight using any USB port. But the battery will no longer give out its 5 volts, since it will only charge from 4 volts.

These were the readings of the multimeter before charging.

Bicycle lights. these are very necessary and important elements for a bicycle. After all, due to them, we safely drive on the roads. And it’s not difficult to make it, the main thing is to have patience, and everything will work out.!

Front lamp from scrap materials

To make a bright lantern for a bicycle with your own hands, first of all, let’s decide on an LED. In our case, the heart of the circuit will be a 10W CREE XM-L. Its light output of 1000 lm is enough not only to illuminate the roadway, but also to surprise the drivers of oncoming traffic. To form a narrow beam, you need a small lens and a mount for it. As a retainer, you can use a flange from a P213 transistor and a part of a plastic tube from a coil. The basis for the flashlight is a radiator from the computer processor, in which you need to drill two holes for attaching the LED, two for the wires and two for attaching the focusing lens. First, we fix the LED, not forgetting to apply thermal paste. Then we pass the wires through the holes and solder to the plus and minus CREE XM-L. The next step is to assemble the focusing part. You may need to experiment with the focal length and shorten the tube length a little. Next is the case. You can take parts from an old bicycle headlight, or you can make it yourself from foil PCB. The dimensions of the case are selected individually, depending on the shape of the radiator. This design provides a place for the driver (you can see its diagram in this article) and a microswitch located behind the radiator. The front of the lens is protected by plexiglass, which is held by 4 screws (it would be more efficient and ergonomic to fix it with hot melt glue). We paint the body black and the front lamp on the CREE XM-L LED is ready to be mounted on a bicycle. It remains to stock up on two lithium batteries and you can hit the road.

Homemade taillight from an old reflector

Assembling a tail light on a bicycle with your own hands is also easy. We will take as a basis an ordinary reflector in a plastic case, which is an integral part of any bicycle. In addition to him, we need:

  • red LED;
  • radiator;
  • thermal paste;
  • two copper wires;
  • foil textolite;
  • hot melt.

The first step is to disassemble the reflector: separate the reflector from the body using a clerical knife. The reflector is securely glued to the rear cover to withstand strong vibration while riding. Therefore, separate the component parts carefully, otherwise the reflector may crack. The next step is to decide on the LED and how to mount it. In the simplest case, an aluminum plate can be fixed inside the case, which will serve as a radiator. Due to the fact that the efficiency of such a heat sink is rather low, the power of the LED should not exceed 0.5 W. But in this design, the internal space is enough for a flat radiator and several smd-LEDs, after which the glowing reflector can be assembled back.

The second method involves the installation of a more powerful radiator with fins that improve heat dissipation. Any radiator removed from Soviet equipment or from the processor of an old computer is perfect. We cut it to the required size, try on and drill two holes for attaching the LED. Then we drill 4 holes in the plastic case with a diameter of 4.5 mm for the screeds. Nylon ties should not be the thinnest, for example, 4 mm by 160 mm, with which we firmly tighten the radiator with the reflector body.

Now we install a 1 W red LED on the radiator with the obligatory application of thermal paste. We solder two wires of pre-planned length to the LED and bring them to the plug on the other side. The entire assembly must be connected to a power source through a driver or, in extreme cases, through a resistor. Since the resulting structure is open from four sides, we make an edging from foil-clad fiberglass of the required height. We install this part of the body and put on the reflector on top. When all the parts of the rear light are assembled, you need to fix them together with hot melt glue. We also use glue to insulate the gaps in the places where the screeds pass.

The made lantern is completely sealed, which is both good and bad. On the one hand, such a taillight is completely protected from all weather conditions. On the other hand, the PCB and plastic housing hinders the cooling of the LED.

To reduce heat loss on the LED, a homemade taillight can be improved in several ways:

  • connect the LED to an adjustable driver, setting the half power mode;
  • use a radiator of a different form factor to avoid complete isolation;
  • install some super bright red LEDs like smd 3014.

Making a lamp for a bicycle with your own hands

The market for bicycle parts is replete with various flashlights and headlights, but it is always more pleasant to make such a part yourself. over, it is not too difficult and also gives room for creativity: you can choose the color of the beam, the size of the body and the method of mounting, adjust the intensity of the glow, etc. How to make a headlight for a bicycle, you will learn from further instructions.

Let’s start assembling

Let’s figure out further how to make a lantern for a bicycle with our own hands. First, we fix the lens in the front of the case with hot melt glue. Hot melt glue is the most reliable option, but if one is not available, a good superglue can be used, subsequently sealing the remaining gaps with a sealant.

Attached bicycle light on the handlebars

Install the LED at some distance from the lens, having previously fixed it to the radiator. You will need to drill holes in the radiator to remove the wires. At this stage, you need to power the device and find out what is the optimal distance. Try your flashlight in a dark room, directing a beam of light onto the wall. this way you can most clearly evaluate the result.

Fix the radiator in place. Depending on which case you managed to find, choose a mounting method. Perhaps the hot melt glue will not be enough, then you will have to drill holes on the sides and fix the radiator with screws.

Now you need to install the back cover of your flashlight. If it is not provided in the case, you can cut it out of a piece of plastic. There must be a distance between the radiator and the cover. Fasten the batteries on the inside of the cover, and on the outside. the switch, connecting it according to the installation diagram of your LED. Place the cover on the body. Best of all, if the cover is secured with screws, then it can be removed to replace the batteries.

What do you need?

The easiest way to construct a flashlight is with these elements. Now on sale there is a huge selection of LEDs for every taste. You can choose the color and power according to your needs. The color of the beam can be either blue or red, but ordinary white LED illuminates the expensive nightlife best. If you want to get a really bright headlight on your bike, we advise you to consider elements with a power of at least 10 watts. In this case, drivers of oncoming traffic will experience a great shock when they find an ordinary bicycle where they expected to see at least a motorcycle. For a medium-power flashlight, a 5-watt LED will suffice.

You will need it so you can turn your flashlight on and off.

How to make a headlamp using an LED? This requires a lens. It is necessary to direct the light flux. Please note that the lens will be at some distance from the LED. You can take a piece of thick acrylic glass. then the lens will turn out to be strong and light, or you can disassemble an old magnifying glass and use it in business.

It is required to dissipate heat from the LED. CPU heatsink can be used.

How to make a suitable lantern for a bicycle with your own hands so that its glow is enough to illuminate the night road? You will need to take such batteries, the power of which will be enough to power the LED you have chosen.

The body is of sufficient size and suitable shape to accommodate and fix all the necessary parts in it.

  • Hot glue or super glue and sealant.
  • Tools for the job.

Bike mount

We figured out how to make a flashlight for a bicycle, now you need to attach it to your vehicle. The easiest way to do this is with a conventional plastic clamp. Drill the body of your device on both sides closer to the back wall, best of all, where there is a distance between the heatsink and the back wall. Insert a plastic strap through the hole and tighten it to a convenient location on the handlebars of your bike.

Done! You have made a bicycle flashlight with your own hands. It’s time to test it thoroughly in the evening driving conditions. Remember to bring your regular flashlight with you in case something goes wrong and your new bike flashlight needs work. Good luck on the road!

Step 2

Now you need a drill with a 4mm drill bit, with which you need to drill 2 holes in the battery compartment. Having done this, take the screws with a thin head and screw the mount from the reflector to the compartment with a screwdriver. You should end up with the photo below. It is important to know that if the screws are with a high head, then the crown will stick out from the compartment and the top cover in this case will not close.

Step 3

Well, we have already done half of the work, and there is very little left. Next, you need to take an LED strip 15 cm long and cut it with scissors into 3 pieces of 5 cm each, and then clean the contacts on one side of each piece with a clerical knife. When stripping the contacts, be sure to observe the polarity. from the top. down below

Step 1

Take your old reflector under the seat and remove the two-hole mount from it. Then attach this mount to the back of the battery compartment (where the switch is) and mark exactly in the center with a pencil or marker the positions of the future holes.

Step 4

We take our prepared battery compartment and glue the LED strip in three rows on the front side. Be sure to glue it so that the stripped pins are closer to the wire coming out of the compartment. Now, with a soldering iron, using flux and solder, tin all the contacts on the tape, then solder two thin wires, connecting them all the pros and cons.

How to make a tail light for a bicycle?

Published: 10/18/2014 at 20:29 / Posted by Sergey Khmaruk

Hello to all cycling enthusiasts! In today’s article, I want to share with you my little work, which you may be interested in. I know there are many ways to make something like this on the Internet, but I want to add my own development.

In general, now I will tell you how to make a tail light for a bicycle in a couple of hours without much difficulty. Yes, that’s how much time it took me for all this work. Well, let’s not pull the cat by the tail, let’s get to work!

  • Silicone LED strip. 15 cm.
  • Battery compartment with built-in switch.
  • Crown battery 9V.
  • Mount from reflector.
  • 2 small screws, nibs, nuts.
  • Thin soldering wire. 10 cm.
  • Silicone sealant.

So, with the main components sorted out, now you need to prepare the tool for work. Here is a list of everything you need:

  • Soldering iron from 25 W.
  • Solder flux.
  • Stationery knife.
  • Scissors.
  • Nippers.
  • Screwdriver (flat or curly, depending on the screws).
  • Pencil or marker.
  • Drill and drill bit 4 mm.

Now, after you have collected all this to a heap, you can start making an LED headlight for a bicycle. All work, for better clarity, I have broken into several steps.

Step 5

Well, our headlight is almost ready, but there is still a little left. We need to cover the soldering points with silicone sealant. Take a small tube of silicone and apply it evenly at the seams perpendicular to the strips of the LED strip. Let it dry for a few hours, then place the crown in the compartment and secure it to your bike. Now you can use.

As you can see, we have got a not very complicated, yakriy and quite attractive rear light for a bicycle. It is also pleasant that everything is done by hand without much effort and knowledge. I hope you like my idea. And even if you will not make yourself such an LED bike light, you can advise your friend or fellow cyclists. Perhaps this kind of homemade product will be useful to someone.

That’s all for me, and if you want, leave your Комментарии и мнения владельцев below about improvements, modifications, or suggest your own development of rear dimensions. If something was not entirely clear, you can also watch my video, in which I clearly show how to make a taillight for a bicycle. Thank you for your attention, see you soon!

Roomy mount for your bike

Once I saw a plastic container on sale. boxes for vegetables. I bought the most suitable one and got to work. The box is plastic, not rigid, the weakest point for attaching to a bicycle. bottom.

To strengthen the structure of 4 mm plywood, we cut out the workpiece to the size of the bottom. Only fixed not inside, but outside. Box dimensions 140x300x400 mm.

From a metal strip 2×20 mm with an angle grinder we cut out four blanks 2x20x180 mm. And since the standard rear rack is 140mm wide, the slats overlap its width.

I stepped back from the edge of the strip by 15 mm and drilled a hole in them. From them they laid 20 mm to the center of the workpiece and drilled holes d 6 mm. they just brush the edges of the barrel rods.

The corresponding holes are drilled in the plywood. He connected the blanks-slats, a regular bicycle rack, plywood, a box and screwed it down with MB nuts. It turned out, maybe not entirely aesthetically pleasing, but convenient.

Where does your energy go?

We have described a bicycle as a machine, and scientifically, this is exactly what it is: a device that can increase force (making it easier to go uphill) or speed. It is also a machine in the sense that it converts energy from one form (everything, what you ate) to another (the kinetic energy of your body and bike as they ride). You’ve probably heard of a law of physics called conservation of energy, which says that you can’t create energy out of thin air or make it disappear without a trace: anything you can do. is to convert it from one to the other. So where does the energy do you bike ride? In scientific terms, we say that it means getting the job done. but what does this mean in practice?

Riding a bike can sometimes feel like hard work, especially if you are riding uphill. In the science of cycling, hard work means that you sometimes have to use quite a lot of force to pedal at any distance. If you are going uphill, you need to work against gravity. If you are walking fast, you are working against the force of air resistance (drag) pressing on your body. Sometimes there are irregularities; on the road on which you need to drive; it requires more strength and uses energy too (bumps reduce your kinetic energy, reducing your speed).

But whether you are going uphill or downhill, fast or slow, on a flat road or a bumpy road, there is other work that always you just need to make your wheels spin. When the wheel is on the ground, supporting the load of, for example, a cyclist, the tire wrapped around it is crushed in some places, bulging out in others. As you go in circles, different parts of the tire contract and bulge, and the rubber they are made of pulls and pushes in all directions. Repeatedly squeezing the tire in this way is a bit like kneading a loaf: it takes energy. and this energy is known as rolling resistance. The greater the load on the tire (the heavier or more you carry), the higher the rolling resistance.

For a racing bike that rides fast, about 80 percent of the cyclist’s work goes into overcoming air resistance, and the rest. to combat rolling resistance; much slower for the mountain biker on rough terrain, 80 percent of their energy is spent on rolling resistance and only 20 percent is lost on dragging.

Chart: Slow mountain bikes spend most of their energy due to rolling resistance; faster racing bikes spend more due to air resistance.

How much energy are we really talking about? In the Tour de France, according to the fascinating Analysis by Training Peaks, the best riders have an average of about 300-400 watts of power, which is roughly 3-4 old-fashioned 100-watt bulbs, or about 15 percent of the power required to run an electric teapot. In comparison, you can generate about 10 watts with a handheld power generator, although you cannot use one for very long without getting tired, what does that tell us? It is much easier to generate large amounts of energy over a long period of time using large leg muscles than using arms and hands. This is why bicycles are so smart: they use the most powerful muscles in our body.

What’s so great about bicycles?

Chart: Comparison of the efficiency of everyday machines (approximate, indicative values, expressed as a percentage). With the exception of the bicycle, new technologies (eg diesel engines) are usually more efficient than older technologies (eg steam engines).

What’s so good is that they get you to places quickly, without consuming fossil fuels like gasoline, diesel and coal, or creating pollution. They do this because they convert the energy produced by our body very efficiently in kinetic energy (energy of motion). In fact, as you can see from the diagram opposite, these are the most efficient vehicles ever developed by humans. By using the strength of your muscles in a surprisingly efficient way, a bike can convert about 90 percent of the energy you give to the pedals into kinetic energy that propels you forward. Compare that to a car engine, which converts only about a quarter of the energy from gasoline into usable power. and at the same time produces all kinds of pollution.

Think of it this way: If you are driving wherever you go, you are carrying a piece of metal that probably weighs 10 to 20 times more than you (a typical compact car weighs over 1000 kg or 2000 pounds). What a waste of energy! Ride your bike and the metal you need to move with you is more than 6-9 kg (14-20 lbs) for a light racing bike or 11-20 kg (25-45 lbs) for a mountain bike or hiker, which is or your own weight.

Higher efficiency means you can cycle further on the same amount of fuel, which is another great advantage of bicycles, although difficult to quantify. According to the classic book Cycling Science by David Gordon Wilson et al: Racing Cyclist at 32 km / h (20 mph) could travel over 574 kilometers per liter (1350 mpg US) if high energy liquid food existed. gasoline. “Whatever one may say, the bikes are simply amazing!

How bike gears work

A typical bicycle has three to thirty different gears. toothed wheels are linked by a chain, which makes the car faster (in a straight line) or easier to pedal (go uphill). Larger wheels also help to drive faster in a straight line, but this is a big drawback when it comes to hills. This is one of the reasons why mountain bikes and BMX bikes have smaller wheels than racing bikes. Not only do the gears on the bike help increase pedaling power when you go uphill: the pedals are attached to the main gear by a pair of cranks: two short levers that also increase power. that you can attach with your feet.

Gears can significantly affect your speed. On a typical racing bike, for example, the gear ratio (the number of teeth on the pedal wheel divided by the number of teeth on the back of the wheel) can be 5: 1, so one pedal action propels you about 10 m (35 ft) down the street. Assuming you can only move your legs that fast, you can see that the gears effectively make you go faster, helping you move further with each pedaling.

Read more in our main gear article.

Image: Bicycles before gears: Early bicycles like these (known as Penny Fartings or Tall Wheels) had a huge front wheel that effectively increased your speed and allowed you to go very fast in a straight line. There were no gears: the front wheel spun once, when the legs were pushed up and down on the handles (pedals). Going downhill was quite difficult (if you did not take your foot off the cranks), but uphill. almost impossible!

DIY Arc Light makes an unnecessarily powerful bike headlight

Remember when taking your bike out of the headlights meant attaching a large chrome bullet-shaped flashlight to the handlebars and attaching a small generator to the front fork? Turning on the headlight meant the generator was in contact with the front wheel, and the incandescent light turned on for the few feet required for the resistance to be created to force you to stop. This stupid bike headlight. not at all, not at all.

We’re used to seeing [Alex] do all kinds of incredible and sometimes impossible things on his popular YouTube channel KREOSAN. We are also used to watching his videos in Russian, which does not detract from the entertainment value of Andglophones; subtitles, however, are for those who don’t like adventure. Electrodes for his arc light. graphite brushes from an electric tram, and a battery. This is an incredibly schematic set of 98 lithium-ion 18650 cells. The scary rat’s coiled cable socket acts as a ballast, mitigating the effects of short circuits when striking the arc. The reflector is an old foil-covered satellite TV antenna, and the electrodes are in a makeshift holder in place of the horn. It’s bright, noisy, dangerous and smokes like the devil, but we love it.

Fitting it to the front of the bike was, of course, just for fun, and it works despite its erratic nature. Neighbors whose apartments the light was projected could not be contacted for comment, but we assume they were as surprised as we were.

How bicycle brakes work

No matter how fast you move, there comes a time when you have to stop. The brakes on a bicycle work using friction (the force of friction between two objects that slide past each other as they touch). Although some bicycles now have disc brakes (similar to those used in cars) with separate brake discs attached to the wheels, many still use traditional caliper and shoe rim brakes.

When the brake levers are pressed, a pair of rubber shoes (sometimes called blocks) are pressed against a metal inner rim at the front and rear of the wheel. When the brake pads rub firmly against the wheels, they turn. your kinetic energy (the energy you have because you walk together) into heat, which slows you down. Read more in our main article on brakes.

Rim brakes versus disc brakes

Caliper-driven rim brakes apply pressure to the outer edge of the wheel, where it spins fastest, but with the least amount of force. This means that they require relatively little braking force to slow down. wheels (so they can be small and light), although you will still have to press hard and you will have to apply that force longer to get yourself and your bike to stop. One of the big disadvantages of rim brakes is that they are completely exposed to rain from the top and sides and splash from the wheels; if the brake pads and wheels are wet and dirty, there is significant lubrication, the friction between the brakes and the wheels can be up to ten times less than in dry conditions (according to David Gordon Wilson Bicycle Science), and your braking distance will be much longer.

READ  How to properly install the front derailleur on a bike

Disc brakes work closer to the hub, so they need to apply more braking force, which can put stress on the forks and spokes, and are both heavier (which can affect the bike’s handling) and mechanically harder, but they tend to be more effective in wet conditions. weather and dirt.

Browse online bike forums and you will find a wide variety of opinions on which type of brakes are best for different types of bikes, terrain and weather conditions. Some people like disc brakes because they make the bike better; others love rim brakes because they are so simple and straightforward.

Figure: Disc brakes (simplified). When you press the brake lever, the cable or hydraulic line (yellow) acts on the calipers (blue), which press the brake pads against a disc called a rotor (red) attached to the wheel. Because the calipers are attached to one of the forks (gray) and the braking force must pass through the spokes (black) to stop the wheel, disc brakes put much more stress on the forks and spokes than rim brakes.

How bicycle tires work

The friction between rubber tires also works to your advantage and the road you ride on: it gives you grip that makes your bike easier to control, especially on wet days.

Like car tires, bicycle tires are not made of solid rubber: they have an inner tube filled with compressed (compressed) air. This means that they are lighter and more resilient, which provides a more comfortable ride. Pneumatic tires, as they are called, were patented in 1888 by Scottish inventor John Boyd Dunlop.

Different bicycles have different types of tires. Racing bikes have narrow, smooth tires designed for top speed. (although their “thin” profile gives them higher rolling resistance), and mountain bikes have thicker and stronger tires with deeper tread, more contact with the road and better traction (although, being wider, they create more air resistance).

Headlights for a specialized tricycle

Oddly enough, there are tricycles for adults too. A tricycle with a headlight requires additional lighting sources, the main task of which will be to indicate the size of such a vehicle. Often, such units are moving stalls with food or a kind of carts for the sale of flowers, toys, souvenirs. Considering that they are most often common in tourist places, they simply need taillights, front and additional ones. Since it will be very bright and attractive from the outside.

A tricycle with a headlight is equipped with a sufficiently powerful lighting. If the front lighting is installed, as in the usual ones (on the handlebars, above the fork or on it), then it is better to mount the rear light either on the frame in the area of ​​the rear wheel, or behind on the basket. The usual place on the tube between the seat and the frame can be closed, and the main function of such headlights will not be performed. marking a cyclist on the road.

Location of headlights

There are several accommodation options:

  • The front handlebar is a traditional placement, but not the best. The light has the form of a spot, at the angle of incidence that comes out as a result, the relief of the road is rather poorly visible.
  • Above the front of the fork. this mount provides more light and is shaped like a long ellipse to better see the road.
  • On the front on the fork, on both sides. the bicycle headlight, placed in this way, can illuminate the road as much as possible. This setup is used for night driving in difficult terrain.
  • If a tail light is installed on the bike, it helps to identify the cyclist on the road.

Of course, reflectors can be used, but headlights are the option that will provide maximum safety. These are the main accommodation options. In addition to them, if desired, you can install additional ones on the frame, in the area of ​​the rear wheel or on the steering wheel. Also, a bicycle headlight can be called a flashlight on a cyclist’s helmet.

What are the lighting elements?

A modern bicycle headlight most often has a single LED, which is powered by a battery or rechargeable battery. Such lighting can be of different sizes and installation patterns. Mostly it is attached with special clamps to the steering wheel. The headlights for a cyclist on a somewhat limited budget can be ordinary flashlights of different power and, accordingly, different luminous power. They are mounted on the steering wheel just to the left of the central part.

There are special bicycle headlights, the manufacturers of which take into account all the requirements of cyclists: strong luminous flux, long operating time, reliable body and glass, convenient fasteners, there are several lighting modes. There are also dynamo headlight options. This means that the light appears when the wheel of the bicycle is set in motion. The light intensity directly depends on the speed of movement. They have a big plus. they do not require battery control, although some cyclists consider such lighting to be the last century.

Bicycle headlights supply

Most bicycle headlights are battery powered. This is very convenient because they can be charged repeatedly. And if on an adult bicycle the headlights will turn on as needed, then a children’s bicycle with a headlight with a small driver, who turns it off and on when he wants, must be equipped with spare batteries. You can carry them with you just in case. After all, a frustrated child, and this is what he will become if he cannot turn on the lighting of his bike, is a thunderstorm of the seas and oceans.

As for the technical characteristics of the batteries, they must support a minimum of 2000 lumens of luminous flux. Such properties are possessed by 18650 batteries, their voltage is 3.4V, and the capacity is up to 5000 mA / h. The more batteries you have, the longer you can ride in twilight or darkness. In reserve, you can have standard AAA batteries, which, by combining in a special cartridge, are able to compare with one battery with the characteristics described above.

Headlight manufacturing

How to make a headlight for a bicycle? This will require the following components:

  • LEDs in the amount required for a specific case.
  • Collimator, provides illumination on the sides.
