Description

一种LED灯板结构 一种LED灯板结构
技术领 域
本发明属于公共照明领域，尤其涉及一种 LED 灯板结构。
背景技术
LED （ Light Emitting Diode ），发光二极管，是一种固态的半导体器件，它可以直接把电转化为光。 LED 的心脏是一个半导体的晶片，晶片的一端附在一个支架上，一端是负极，另一端连接电源的正极，使整个晶片被环氧树脂封装起来。半导体晶片由两部分组成，一部分是 P 型半导体，在它里面空穴占主导地位，另一端是 N 型半导体，在这边主要是电子。但这两种半导体连接起来的时候，它们之间就形成一个' P-N 结'。当电流通过导线作用于这个晶片的时候，电子就会被推向 P 区，在 P 区里电子跟空穴复合，然后就会以光子的形式发出能量，这就是 LED 发光的原理。而光的波长也就是光的颜色，是由形成 P-N 结的材料决定的。
高性能 LED 的实用化和商品化，使照明技术面临一场新的革命。由多个超高亮度红、蓝、绿三色 LED 组成的像素灯不仅可以发出波长连续可调的各种色光，而且还可以发出亮度可达几十到一百烛光的白色光成为照明光源，对于相同发光亮度的白炽灯和 LED 固体照明灯来说，后者的功耗只占前者的 10%-20% 。
现时生产的白光 LED 大部分是通过在蓝光 LED 上覆盖一层淡黄色荧光粉涂层制成的，这种黄色磷光体通常是通过把掺了铈的钇铝石榴石晶体磨成粉末后混合在一种稠密的粘合剂中而制成的。当 LED 芯片发出蓝光，部分蓝光便会被这种晶体很高效地转换成一个光谱较宽的主要为黄色的光，由于黄光会刺激肉眼中的红光和绿光受体，再混合 LED 本身的蓝光，使它看起来就像白色光。
LED 灯条又名 LED 灯带，英文名称： LED Strip ， LED 灯条是指把 LED 组装在带状的 FPC （柔性线路板）或 PCB 硬板上，因其产品形状像一条带子而得名。
