Abstract

本实用新型提供了照明灯领域的一种节能日光灯。该灯是在直流稳压电源的两端并联n个由发光二极管LED1与电阻R3、发光二极管LED2与电阻R4、发光二极管LEDn与电阻Rn﹢2相串联的分支电路构成的。它可在较低的电压下使多个发光二极管同时发出洁净纯白的灯光,亮度高、无污染、无辐射,不含有害气体,且可节省电能90%,节能效果显著。由于灯体是PC塑料制成,坚固不易碎,免维护寿命长(其寿命可比常规灯提高1000倍)。不仅如此,还具有结构简单紧凑、性能安全可靠、使用方便灵活、绿色环保照明、适合推广应用等优点。

Description

节能日光灯
技术领域:本实用新型涉及一种照明灯,尤其是涉及一种可节省电能的日光照明灯。 
背景技术:长期以来人们使用的照明灯都是白炽灯,白炽灯通电后先发热后发光,其中有80%的电能转换成为热能,只有20%用于发光,利用率相当低。随着科学技术的发展,人们研制出日光灯、螺旋灯、U型灯、卤素灯等充气灯,它们都是通过填充气体,镇流升压激活发光物来产生光。这些灯虽说是能节省一部分电能,但易碎,而且含有有害气体{如铅、汞}对环境有污染并存在光辐射。 
发明内容:本实用新型的目的在于提供一种节能日光灯,主要是解决现有照明灯电能利用率低,损失大,容易碎,而且含有有害气体污染环境并存在光辐射的问题。 
本实用新型如下所述:该实用新型包括壳体、印刷线路板、由电源开关K1、降压电阻R1、电容C1、镇流二极管D1-D4、电容C2、电容C3、稳压二极管D5、电阻R2构成的直流稳压电源,还包括发光二极管LED1-LEDn、电阻R3-Rn+2,它是通过在直流稳压电源的两端并联n个由发光二极管LED1与电阻R3、发光二极管LED2与电阻R4、发光二极管LEDn与电阻Rn+2相串联的分支电路构成的。其中n为自然数。 
本实用新型的有益效果:该实用新型由于采取了上述结构,可在较低的电压下使多个发光二极管同时发出洁净纯白的灯光,亮度高、无污染、无辐射,不含有害气体,且可节省电能90%,节能效果显著。由于灯体是PC塑料制成,坚固不易碎,免维护寿命长(其寿命可比常规灯提高1000倍)。不仅如此,还具有结构简单紧凑、性能安全可靠、使用方便灵活、绿色环保照明、适合推广应用等优点。 
附图说明:图1是节能日光灯的电路图。 
具体实施方式:由图1所示的节能日光灯,是在交流220V电源串入电阻R1与电容C1的并联支路,再接入由镇流二极管D1-D4组成的镇流器,经电容C2、C3滤波、二极管D5稳压,构成4V直流稳压电源。电阻R2为保护电阻,它是在瞬间电流过大时对灯起保护作用。在直流稳压电源的两端并联由发光二极管LED1与电阻R3、发光二极管LED2与电阻R4、发光二极管LEDn与电阻Rn+2相串联的n个分支电路构成的。 
安装时,除了电源开关K1外,其它所有部件都安装在印刷线路板上,发光二极管LED1-LEDn一般为一字形排列。当然,也可根据节能灯外部壳体的不同而采取其它的排列方式。印刷线路板放在壳体内,经电源开关K1接通电源后,发光二极管LED1-LEDn便可透过壳体向外发出洁净纯白的日灯光。使用该灯5W,与普通白炽灯40W相比不仅更亮,而且每只灯每年可节省电费300多元。节能效果十分显著。
