Abstract

本实用新型涉及了一种电光源日光灯,主要解决现有日光灯发光效率低、成本高、寿命短的问题。本实用新型采用灯管外套玻璃明管,之间真空的结构形式,具有亮度高、寿命长的显著特点。

Description

日光灯
所属技术领域
本实用新型涉及了一种电光源日光灯。
背景技术
现在日光灯主要由灯管、灯脚、灯丝组成,日光灯管的荧光粉主要采用卤粉,发光效率低(31Lm/w),使用寿命短(1000h),显色性差(55Ra),长期在这种光照下学习、工作,会对人的视力产生不良影响;也有采用稀土三基色荧光粉生产日光灯管,但这种灯管与现有的日光灯灯架不配套,更换灯管需整套更换,价格高,一次性投资较大。另外,稀土三基色荧光粉要在50℃左右发光效率最高,现有稀土三基色灯管细、长,靠自身温度很难达到50℃,不能发挥其最佳发光效率。
发明内容
本实用新型是解决现有日光灯管发光效率低、寿命短及采用稀土三基色荧光粉灯管成本高,亮度差的问题,实现低成本、高亮度,延长灯管寿命的目的。
本实用新型技术方案:在现有日光灯管结构基础上,采用稀土三基色荧光材料灯管,灯管外套玻璃明管,灯管与玻璃明管夹层真空。
本实用新型的有益效果是灯管与外层玻璃管之间真空起到保温作用,能迅速提高灯管温度,使之达到并保持50℃左右,保证荧光粉发挥最高亮度(显色性85Ra),光效达到80Lm/w,是传统日光灯的2.5倍。外层玻璃管避免了灯管直接与自然环境接触,减少了荧光粉亮度衰减,延长了灯管使用寿命(5000h),是传统日光灯管的5倍。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
附图为本实用新型实施例结构示意图
图中,1灯脚,2灯丝,3三基色荧光灯管,4玻璃管
具体实施方式
图中,灯丝(2)探入三基色荧光灯管(3)两端,灯管(3)外套玻璃管(4),灯管(3)与玻璃管(4)之间抽真空,玻璃管(4)两端按装灯脚(1)。
本实施例为40w,灯管(3)采用T5灯管,玻璃明管(4)采用T8,长度为1200mm。
