Description

节能照明灯
技术领域
本实用新型属一种节能照明灯。
背景技术
在一些公共场合或家庭里,常需要安装夜间“常明”的照明灯,即通宵照明,虽然这类灯不需要太亮,可以使用功率小一些的灯泡,但由于工作时间长,耗能还是较多,而且使用寿命短。
发明内容
本实用新型要解决的技术问题目是提供一种耗能少、寿命长,特别适于夜间常时间工作的节能照明灯。
解决上述问题的技术方案是(参见实施例图):本实用新型设有电源连接头(1),壳体(2),其特征在于:所述的壳体内装有控制电路板(3),控制电路板上设有与电源连接头(1)电连接的整流电路,整流电路输出端与发光二极管(5)电连接。
通常钨丝灯和日光灯的衰老时间为2000小时左右,发光二极管的衰老时间则为3万小时以上,而且发光二极管的消耗功率仅为相同亮度钨丝灯泡的约三百分之一,因此本实用新型特别适用于需要长时间照明的场合,具有寿命长、耗能少的优点。
附图说明

图2、本实用新型实施例电路方框示意图
图3、本实用新型实施例电路图
1-电源连接头  2-壳体  3-控制电路板  4-反光罩  5-发光二极管
具体实施方案
本例的电源连接头1为通常的螺旋灯头,可拧入与交流电源连接的螺旋灯口里,壳体2与电源连接头1连为一体,壳体内装有反光罩4,控制电路板3装在壳体2与反光罩4之间的夹层里,控制电路板设有与电源连接头交流电源连接的整流电路,整流电路输出端通过光控开关电路接发光二极管5,发光二极管装在反光罩里。
整流电路由二极管D1、D2、D3、D4组成,输出端接有滤波电容C2,整流电路输出端与发光二极管的连接回路里串联有开关三极管2N5041,其基极接有光敏电阻CDS,开关管2N5041、电阻R3、R4、二极管D5和光敏电阻CDS组成光控开关电路,白天光线强时,开关管2N5041关断,发光二极管不工作,夜间光线暗下来时,在光敏电阻作用下,开关三极管导通,发光二极管工作。
本例设置的光控开关电路可使发光二极管白天自动关断,晚上自动点亮。
本例的发光二极管规格为φ18mm,工作电压3.6伏,功率0.006W,与本实施例发光二极管相同亮度的钨丝灯泡工作电压为3.6伏,功率为2W,由此可见本实施例的耗能很少。

Claims (3)

1、节能照明灯,设有电源连接头(1),壳体(2),其特征在于:所述的壳体内装有控制电路板(3),控制电路板上设有与电源连接头(1)电连接的整流电路,整流电路输出端与发光二极管(5)电连接。
2、根据权利要求1所述的节能照明灯,其特征在于:所述的壳体(2)内装有反光罩(4),控制电路板(3)装在壳体(2)与反光罩(4)之间的夹层里。
3、根据权利要求1或2所述的节能照明灯,其特征在于:所述的整流电路输出端通过光控开关电路接发光二极管(5)。
