Description

一体式冷阴极荧光支架灯 技术领域
本发明涉及一种照明灯具，特别是一种一体式冷阴极荧光支架灯。
背景技术
传统 的T 5/T8 等其它日光灯，作为一种装饰背光、以及格栅照明，存在功耗较大，寿命短，光衰快，约 3000H 衰减 50% 、耐开关次数低，约 10 万次等缺点，长期点灯、开关次数多会导致灯管提前老化，需要经常更换，维护费用高，且整流器寿命也不高，镇流器与灯管需分开安装，不节省空间。
现有的T5/T8支架灯存在以下缺点：
1. 使用电感整流器驱动，存在频闪现象（50Hz交流电每秒亮灭50次），会给人眼造成较大影响，长时间使用很容易引起视觉疲劳，对使用者的视力，特别是青少年的视力造成危害；
2. 灯管为传统荧光灯管，使用寿命短，只有8000小时左右，灯管用荧光粉质量低，在显色指数上通常难达到80Ra,显色性差；
3. 使用整流器驱动，频繁开关易坏驱动元器件，再次打开时会出现闪烁现像，寿命短、需经常更换；
4. 灯管内水银含量很难控制，不利于环境保护；
5. 多根支架灯组合安装时，需要外壳；
6. 一般支架灯光损失很大。
