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 ...
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 ...
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 ...
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 ...
