This teardown of a recent greenback retailer instance shows that cost-chopping has managed to shave even more off what was already wanting like a market saturated with bottom-greenback design. The electrical elements inside this glowing mannequin of cost-chopping consists of one PCB (beforehand-seen dollar store LED bulb examples had two), EcoLight products eleven LEDs, one bridge rectifier, two resistors, and a controller IC. A wirewound resistor apparently additionally serves as a fuse, simply in case. IC to see what lurks inside, and the result is shown right here. 100 Volts DC that the bridge rectifier and enormous electrolytic cap present to it, and it’s both cheap and clever in its personal method. The top half is a big transistor for chopping the voltage and the bottom half is the easy management logic
