Description

LED半导体节能灯
一、技术领域
本设计LED半导体节能灯属电子灯具。 
二、背景技术
用超高亮度发光二级管(简称LED)作成的灯具是目前最节能的灯具，比白炽灯节能近五倍，比一般节能灯节能二倍。由于LED为低压器件，因此，LED须经一降压器电路才能与市电相连接使用。现今能实现降压的电路有许多，但寻求小电流型的降压简单、安全、能耗更小的LED驱动用降压器电路仍是令人关注的问题。 
三、发明内容
本设计的目的在于提供一种有降压更简单、安全、能耗更小的降压器的LED半导体节能灯。 
为实现上述目的，本设计提供的一种LED半导体节能灯由LED及其低压直流驱动电源电路构成。该驱动电路由降压电容C1，整流桥Vc，分压-滤波电容C2，稳压管Vs构成。其降压电容为1～3μf容量，400V以上耐压的高压电容，分压-滤波电容为大容量(20μf-470μf)低耐压(≥16V-63V)小体积电解电容，稳压管Vs稳压值视LED要求而定，LED主要为3～5W超高亮度发光二级管。 
本节能灯电路在作路灯使用时，还可在所述驱动电路的直流输出端加入由光敏电阻Rg控制的可控硅V构成的光控开关，实现对LED灯白天灭晚上亮的自动控制。 
本节能灯工作时，220v市电由C1降压后经VC整流再经C2滤波和VS稳压后直接或再通过光控可控硅开关电路驱动LED。这里节能灯电路实质上可认为是LED和电容两者以并联方式与市电相连。因此，由于电容的存在，节能灯的接入对电网而言，其功率因素，必然得到了改善，这在另一意义上本节能灯也在节能。 
四、附图说明
附图1为本LED半导体节能灯电路原理图，附图2为其具体实施电路之一图，附图3为本节能灯在作路灯使用时的光控节能灯电路图。 
五、具体实施方式
如附图2所示，一种LED半导体节能灯，它由电容C1(1μf/400v)、整流桥Vc(4×1N4007)、分压-滤波电容C2(470μf/16v)、稳压管(5v)和LED(3w.5v)构成。 
本设计已制成样品和经成功的试验。
