| Abstract |
A flat fluorescent lamp (FFL) developed as a light source for LCD TV backlight was used as a light source for general lighting application and its electro-optical characteristics were treasured and evaluated. The channels of FFL were formed from a flat glass at high temperature by using a mold The performance of FFL with lighting fixture was shown to improve by optimizing the channel profile of FFL. In this paper, the brightness efficiency of FFL with lighting fixture was evaluated and compared with that of the hot cathode fluorescent lamp (HCFL), the major light source for general lighting. The optical efficiency of FFL with fixture was shown to be 72.7[lm/W]. |
