Abstract

本实用新型涉及一种灯具。长寿命日光灯是用普通金属丝代替日光灯管,除适用于家庭、学校、机关、宾馆外,尤其适用振动比较大的火车、汽车及生产车间的照明。用普通金属丝做日光灯的灯丝,能为国家节约大量的贵重金属,简化了生产工艺,降低了成本,使用寿命长,节约能源。

Description

本实用新型属于一种灯具。
本发明的目的在于提供一种新型长寿日光灯。在已有的技术里日光灯管是用钨丝做发光源,但钨丝点燃寿命也比较短,受到振动灯丝容易断,镇流器本身也要消耗掉一部分电能。
为了克服上述缺点,本发明取消了日光灯管内的灯丝,采用了一般金属丝代替了钨丝。这样可为国家节约大量的贵重金属,使日光灯管制造工艺简化,成本下降20-30%左右,可比目前使用的日光灯管提高使用寿命五倍以上,比同样瓦数灯管功率因数提高20-40%左右,节电15-30%,各项技术指标都很理想。
实施例:
长寿命日光灯管的构造如图1所示:1.灯管,2.荧光粉层,3.4.固定接头,5.6.绝缘片,7.8.金属丝。其工作原理如图2所示:将灯管1的两端金属丝7、8接入供电器的3、4端,供电器的1、2端接入220V电源,供电器产生的电子流进入灯管两端金属丝7、8端,电子流通过金属丝尖端放电的原理进入灯管内,打到荧光粉上而发出光亮来。
附图1中:1.灯管,2.荧光粉层,3.4.固定接头,5.6.绝缘片,7.8.普通金属丝。
附图2中:1.2.电源,3.4.供电器接线端,7.8.灯管金属丝。

Claims (3)

1、一种由普通金属丝代替钨丝做日光灯丝的长寿日光灯管,其特征在于不再使用贵重金属钨丝作为日光灯的灯丝。
2、按照权利要求书1所述的长寿日光灯管的两端金属丝尖端放电的原理进入灯管内,打到荧光粉上而发出光亮。
3、按照权利要求书1.2.所述的长寿日光灯管是由专用的供电器配套使用。
