HI!!! i have a project in hand and i need to used an solar energy suplly and 40 LED´S to do a STREETLIGHT, the problem is that i don´t know what i need to build the circuit
can anyone HELP me????
SOLAR ENERGY + 40 LED´S + right circuit = SOLAR LED STREETLIGHT
What do you want to use this for?
You could have a motion sensor turn on this device when someone walks near it which would dramatically reduce the panel and battery requirements.
But actually lighting several hundred sq ft adequately would require a LOT of LEDs, being on intermittently will not change that problem. You could overdrive them a bit but that only goes so far.
Sad truth is sodium/mercury vapor lights are actually substantially more efficient than LEDs or compact flourescent. Actually even the CFL is more efficient than LEDs.
