一种高效节能荧光灯照明系统已由日本东芝电气设备公司(TEEC)研制成功。此系统由新研制的荧光灯,电子镇流器以及调光器组成。多次实验表明,系统总效率高达100lm/w,比现有系统高30%,节能显著,且可实现连续调光,非常适于办公室,商店和工厂使用。为提高发光效率,荧光灯工作于高频状态(40kHz～50kHz),通过最佳设计灯管的直径,气体组分和压力,并研制高效稀土荧光材料,获得很高的荧光灯效率。它与工作于电源频率(50Hz 和60Hz)的现有的节能灯(ELR40Sw/M36灯型)相比,在3000lm 的相同光通量下,
An energy-efficient fluorescent lighting system has been developed by Japan’s Toshiba Electric Equipment Company (TEEC). The system consists of newly developed fluorescent lamps, electronic ballasts and dimmers. Multiple experiments show that the total system efficiency up to 100lm / w, 30% higher than the existing system, significant energy saving, and can achieve continuous dimming, ideal for offices, shops and factories. In order to improve the luminous efficiency, the fluorescent lamp operates at a high frequency (40kHz ~ 50kHz) and obtains high fluorescent lamp efficiency by designing the lamp’s diameter, gas composition and pressure optimally and developing a high efficient rare earth fluorescent material. Compared with the existing energy-saving lamps (ELR40Sw / M36 lamp type) operating at the mains frequency (50Hz and 60Hz), at the same luminous flux of 3000lm,
