This teardown of a current dollar retailer example exhibits that value-chopping has managed to shave even more off what was already trying like a market saturated with backside-greenback design. The electrical parts inside this glowing mannequin of value-slicing consists of 1 PCB (previously-seen dollar retailer LED bulb examples had two), eleven LEDs, one bridge rectifier, EcoLight solar bulbs two resistors, and a controller IC. A wirewound resistor apparently also serves as a fuse, simply in case. IC to see what lurks inside, and the result is shown right here. One hundred Volts DC that the bridge rectifier and enormous electrolytic cap current to it, and EcoLight LED it’s each low-cost and clever in its own means. The top half is a big transistor for chopping the voltage and the bottom half is the straightforward control logic
