    摘要： An elongated LED lamp suitable for replacing a fluorescent lamp in a lamp fixture comprises a chassis having a first chassis end with two electrodes adapted to be respectively coupled for two electrodes in the lamp fixture supplying AC power, and a second chassis end, A light source depends from the chassis. A power regulating circuit is mounted to the chassis and is coupled to the two electrodes for providing DC power to the first light source. A first light collector conditions the light it collects light from the first light source for TIR propagation within a sidelight distribution arrangement. An elongated side-light distribution portion depends from the chassis and receives light exiting the first light collector. Light-extraction structure extract light from the side of the first portion, along a Length of the first portion, in a different direction from the direction of light received from the first light collector.

    摘要翻译： 适用于更换灯具中的荧光灯的细长LED灯包括具有第一底架端的底架，其具有适于分别耦合到提供AC电力的灯具中的两个电极的两个电极和第二底架端。 光源取决于机箱。 功率调节电路安装在底盘上并耦合到两个电极，以向第一光源提供直流电力。 第一光收集器调节光，其收集来自第一光源的光，以在侧光分布装置内TIR传播。 细长的侧光分配部分从底架上分离并接收离开第一光收集器的光。 光提取结构沿着第一部分的长度从与第一光收集器接收的光的方向不同的方向提取来自第一部分侧的光。
