Hi. In an autumn it began dark to return from working on bicycle, it was time to make light-emitting-diode headlights for my ferrous horse.
All was begun with that I found in the internet the interesting idea of case/heatsink for headlights http://forum.fonarevka.ru/showthread.php?t=422
Ordered details on a draft.
Purchased in a build shop fastening for pipes, added the case of headlights to them.
On a bottom prikrutiv 1w light-emitting diodes. From above added lenses.
Farther collected in a case a lowering impulse stabilizator on Mc34063 with the current of stabilizing of 350ma.
Assemble on a bicycle.
A switch plugs the second light-emitting diode in a successive link. Like near and distant light, as in a car
Powered by bike dinamo.
A bicycle with such headlights now has an own face)))))).
Works all well but two 1w light-emitting diodes not enough for fine illumination – it is needed to put something more powerful.
