Elongated LED Lamp for Replacing a Fluorescent Lamp |
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 to 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 side-light 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. |
