Red led material
Web21. jan 2024 · The LED (light-emitting diode) is a PN junction device that emits light when a current passes through it in the forward direction. Semiconductor materials used for the manufacture of LED are gallium arsenide phosphide (GaAsP) which emits red or yellow light or gallium arsenide (GaAs) which gives green or red-light emission. WebThe most common and profound effects of both red and NIR light include increased cellular energy, reduced inflammation, increased collagen production, and increased blood flow. The difference lies in the ability of longer-wavelength NIR light to penetrate deeper into the body's tissues than red light.
