10 watt led driver | all about circuits

feb 16, 2015 that transistor has to get rid of about .00025 amps. that puts the vbe a little below .6 volts and you want more than 1 amp in the mosfet. r= e/i r = .59v/1.05 amps r = .562 ohms as the circuit gets hot, the vbe will diminish and not cause thermal run away. this is a constant current circuit. it has nothing to do with an led calculator.

automatic street light controller circuit circuit diagram

this circuit is an automatic street light controller. sensors used to detect changes in light is ldr (light dependent resistor), the working principle of light dependent resistor is exposed to light when the resistance value of ldr great, but if not exposed to light or dark then the resistance value of ldr.
