Composition materials of LED chips!
LED CHIP, called CHIP in English, which is the main material to make LED LAMPS (LED LAMP), LED screen (LED Display), LED backlight (LED BACKLIGHT), made of gallium phosphide (GaP), gallium aluminum arsenide (GaAlAs), or It is made of gallium arsenide (GaAs) or gallium nitride (GaN). Its internal structure is a PN junction with unidirectional conductivity.
1. The role of led chips: the chip is the main component of the Lamp, is a semiconductor material that emits light.
2. Composition of led chips: The chip is made of materials such as gallium phosphide (GaP), gallium aluminum arsenide (GaAlAs) or gallium arsenide (GaAs), gallium nitride (GaN), and its internal structure has unidirectional conductivity.
3. The material of the LED chips:
The solder pads of led chips are generally gold pads or aluminum pads. The shape of the pad is circular, square, and cross.
The color of the led chip's illumination depends on the wavelength (HUE). The classification of common visible light is roughly: dark red (700nm), deep red (640-660nm), orange (615-635nm), amber (600-610nm), yellow ( 580-595 nm), yellow-green (565-575 nm), pure green (500-540 nm), blue (435-490 nm), purple (380-430 nm). White light and pink light are a mixture of light effects. The most common is a mixture of blue + yellow phosphor and blue + red phosphor.
