In designs using multiple LED strings such as brake lights, daytime running lights, rear lights and other automotive lighting applications, current-balancing circuits supply equal current to all LED ...

Recent advancements in the development of higher-efficiency LEDs at lower costs have made these light sources the "technology of choice" when designing automotive interior lighting systems. This ...

Fig 1. This voltage regulator circuit (a) uses green LEDs as both the stabilization elements and as the voltage indicators at the front-panel switch (b). Fig 2. The addition of resistor R4 to the ...

LED output is a function of the current through it. So to drive the device, it would seem simple enough to set the LED current with a series power resistor. But there’s a problem with this idea. First ...

I don’t know about you, but although I like reading about electronics in a theoretical sort of way, there’s nothing I enjoy more than the hands-on building of something and then watching that thing ...
