Here is a complete product project of endtas design. Alien Light Mini is a LED headlight for bicycles. It has got two 1W leds, one with a wide angle and the other with a narrow beam angle lens.
The wide lens is a bit turned towards the ground to light up nearby ahead and the other straight ahead for greater distance lighting.
Visit the free product design projects website www.endtas.com for circuit schematic, hex file and other details. There are other projects too.
This is a microprocessor controlled inttelligent light with 9 lighting modes.
Double 5mm led flash
Double 1W leds triple flash
Double 1W leds continuous flash
Continuous power 1st grade + flash/2seconds
Continuous power 2nd grade
Continuous power 3rd grade
Continuous power 4th grade
Continuous power 5th grade
- SOS signal flash mode. Flashes S.O.S distress signal with 2 1W LEDs.
The light circuit is designed to work with two Nokia cell batteries but the prototype is made by using 3AAA type batteries, generating 3.6V aprox. The product can run for days at the minimum power setting and more than 3 hours at max power.
