LED
A light emitting diode (LED) is a semiconductor light source that emits light when current flows through it.
LEDs have many advantages over incandescent light sources, including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching.
LEDs are used in applications such as automotive headlamps, general lighting, traffic signals, camera flashes, horticultural grow lights, and medical devices.
RGB color model
RGB color model
The name of the RGB comes from the three primary colours which are red, green, and blue.
Secondary colours are formed by the sum of two primary colours of equal intensity: cyan is green+blue, magenta is blue+red, and yellow is red+green.
Zero intensity for each colour component gives the darkest colour (no light, considered as black), and full intensity of each gives white color.
