How to Control an LED -- Brightness, Power, and Current
We discuss driving an LED, current mode control, and controlling LED brightness. We make mention of how LEDs are controlled by the power flowing through them, and how forward voltage changes with current. Weighing the differences between constant current and constant power control of LEDs and getting a little distracted by the minutia of LEDs ...

Light-emitting diode LED Lights
What is an LED?_ An LED (Light Emitting Diode) is a type of semiconductor device that converts electrical energy into light. _How does it work?— When a voltage is applied to the LED, electrons recombine with holes, releasing energy in the form of photons, which we see as light. _Key Characteristics:_ ���_Color_: LEDs are available in a range of colors, including red, orange, yellow, green, blue, and white. ��_Brightness_: Measured in lumens (Im) or candelas ���_Voltage_: Typically operate betwee
