The Blue Light Spike There are some key differences between natural sources of blue light, like daylight, and artificial sources, such as the LEDs used in digital devices. Most of the light from the LEDs has wavelengths between 400 and 490 nanometers. Many LED screens peak in the 435-440 ...
LED（Light Emitting Diode）即发光二极管，是一种能将电能转化为光能的半导体器件。在众多LED中，蓝色发...
蓝色LED的材料使用氮化镓(GaN)类半导体。以前曾盛行用硒化锌(ZnSe)类半导体开发蓝色LED,但自从1993年12月采用GaN类半导体的高亮度蓝色LED被开发出来后,蓝色LED的主流就变成了采用GaN类半导体的产品。Vt}QP Nt I9qZE=i 蓝色LED的构造为,在蓝宝石或者SiC底板等的表面上,重叠层积氮化铝(AlN)半导体层和GaN类半导体层...
Therefore, blue light is a high-energy visible (HEV) light with wavelengths ranging from approximately 380 to 500 nanometers. It is emitted by both natural sources, like the sun, and artificial sources, such as digital screens (computers, smartphones, tablets, and TVs), LED lighting, and ...
Hopefully it will significantly reduce the blue light from LED and provide a much higher color rendering index.According to Dr. Sean Hong, Head of Advanced Performance of Lighting and Display Optics Laboratory (APOLLO Lab), BASF Taiwan, the candidate material is a fluorescent dye originally used ...
Transilluminator base and Amber filter unit–light from the LED source inside the transilluminator passes through a blue filter producing a single-intensity signal at approximately 470 nm. The amber filter unit filters light to ~580 nm and provides a large viewing surface. ...
Blue-light-blocking glasses are supposed to protect eyes from the effects of short-wavelength light from our smartphones,computer screens and LED lights.Considering how much time we spend on our phones,we may think such glasses are smart choices,right?After all,eye strain(疲劳) is a real issu...
指蓝色发光二极管。发光波长的中心为 470nm 前后。用于照明器具和指示器等蓝色显示部分的光源 LED 显示屏的蓝色光源以及液晶面板的背照灯光源等。与荧光体材料组合使用可得到白色光。目前的白色 LED 一般采用蓝色 LED 与荧光材料相组合
