- Light-emitting diode - Wikipedia
In a light-emitting diode, the recombination of electrons and electron holes in a semiconductor produces light (be it infrared, visible or UV), a process called "electroluminescence" The wavelength of the light depends on the energy band gap of the semiconductors used Since these materials have a high index of refraction, design features of the devices such as special optical coatings and
- LED灯_百度百科
LED灯是一块电致发光的半导体材料芯片,用银胶或白胶固化到支架上,然后用银线或金线连接芯片和电路板,四周用环氧树脂密封,起到保护内部芯线的作用,最后安装外壳,所以 LED 灯的抗震性能好。
- What is LED? - BYJUS
What is LED? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it When current passes through an LED, the electrons recombine with holes emitting light in the process LEDs allow the current to flow in the forward direction and blocks the current in the reverse direction Light-emitting diodes are heavily doped p-n junctions Based
- What is LED? - Construction, Working, Characteristics . . .
LED (Light Emitting Diode) is an optoelectronic device which works on the principle of electro-luminance Electro-luminance is the property of the material to convert electrical energy into light energy and later it radiates this light energy
- 發光二極體 - 維基百科,自由的百科全書
由於LED的驅動電壓較低,一般家用電壓為100-240V,需要將LED及變壓器包裝為燈泡或燈管才能應用於家中,而在降低成本的考量下,許多市售產品搭配品質較差的變壓器,而加快損壞的可能。 發光二極體光度並非與電流成線性關係,光度調節略為複雜;使用 PWM 為最低成本的調節亮度方法,但頻率
- Led - Wikipedia, la enciclopedia libre
Un diodo emisor de luz o led 6 n 1 (también conocido por la sigla LED, del inglés light-emitting diode) es una fuente de luz constituida por un material semiconductor dotado de dos terminales Se trata de un diodo de unión p-n, que emite luz cuando está activado 7 Si se aplica una tensión adecuada a los terminales, los electrones se recombinan con los huecos en la región de la unión p
- Light Emitting Diode (LED): Principle, Advantages, and Uses
A light-emitting diode (LED) is a small electronic device that emits light when an electric current flows through it LED works by passing electricity through a semiconductor, which releases energy in the form of light This process makes an LED highly efficient, durable, and versatile, finding its applications in everyday devices such as smartphones, TVs, and home lighting systems
