The lighting system in my cousin's bike was very dim. He requested me to build a full LED headlight. After a lot of research that I did about LEDs on the net, I finally came up with a master piece the "TRIDENT". The TRIDENT is the name that I have given my headlight because of the three High Power LEDs that is used. The one thing that I really like about this LED headlight is that it combines power and good looks. It gives the contemporary dot like LED look. The LED headlight gives me good range too.
The LED Headlights can be mounted on a motorcycle or on a bicycle. The headlights can be mounted on the bicycle that you ride to school. It would be a head turner and would attract a lot of attention.
I would like to thank Dipankar, Captain Slug, phephq, Artificial Intelligence, bhvm and many other instructable members who introduced me to this concept and helped me in solving my doubts.
The High Power LEDs are very powerful and causes sort of a flash blind. Do not stare into the LEDs. LED headlights are not DOT approved, so use it at your own risk.
Step 1: Parts Needed:
For making this headlight you need the following parts :
1. 135pcs of white 5mm LEDs( 10000mcd or higher )
2. 15cms x 10cms PCB
3. 3pcs of 1watt high power LEDs
4. Aluminium heatsink
5. Thermal compound
6. 45pcs of Resistors(1/2 watt 120ohms resistors)
7. Capacitor( 100ufd / 50v)
8. 4pcs of Diode IN4007
11. Silicon Sealent
3. Soldering iron
5. Soldering wax.
Step 2: Place the LEDs and glue them in place
Place the 5mm LEDs on the PCB and glue them to the board. I used fevicol since it is cheap, and it dries to become transparent. Remember to leave some area in the centre of the circuit board to mount the heatsink and the high power LEDs. Once you have glued the LEDs on the circuit board, then you should have something that looks like the second image given below.
