Bike LED Lighting system

 Bike LED Lighting system

the author writes: First, the rationale: I don’t want lights on my bike because they’re theft magnets, are more fragile, and more cumbersome. I want a single battery pack that powers a tail light and one or two headlights, and I want to turn it all on or off with one switch. The backpack is the best way to go for me, since I also like to carry my lock in the backpack anyway and always have it with me.

Luxeon LED controller (dimmer)

The small super bright Luxeon LED’s are now widely available so projects based on them start to emerge over the web. As you may know in 1999, Lumileds Corporation of San Jose, CA, introduced the Luxeon LED, a high-power white-light emitter. These days many flashlights incorporate Luxeon LED’s as the light source, and are made of aluminum to dissipate the heat from the Luxeon LED. About the project, its a simple circuit that controlls the Luxeon LED trough a button press. By pressing the button you can select 3 luminous strenghts and at the forth press of the button the Luxeon LED powers off. The board is very small and can be easily fit into any existing flashlight. The source code can be obtain only by requesting it via authors email, so head on Authors page to email him if you want to get the source.
