Abstract

本发明的目的是提供一种方便好用的具有缓慢熄灯效果的LED灯，包括变压器、整流器和LED灯，所述LED灯与数个电容组串联，所述电容组由数个电容并联组成。当开灯时，灯具亮，电容充电；当熄灯时，电容放电，由于电容所蓄电量有限，灯具会慢慢熄灭。

Description

具有缓慢熄灯效果的LED灯
技术领域
本发明涉及一种照明设备，尤其是一种具有缓慢熄灯效果的LED灯。
背景技术
普通的灯具，接通电源瞬间亮灯，断开电源瞬间熄灯，熄灯时人类的瞳孔来不及放大，会产生眼前一片黑暗现象，导致人手足无措，只有静待眼睛适应黑暗再摸索前进。
发明内容
本发明的目的是提供一种方便好用的具有缓慢熄灯效果的LED灯。
本发明是这样实现的：具有缓慢熄灯效果的LED灯，包括变压器、整流器和LED灯，其特征在于所述LED灯与数个电容组串联，所述电容组由数个电容并联组成。
当开灯时，灯具亮，电容充电；当熄灯时，电容放电，由于电容所蓄电量有限，灯具会慢慢熄灭。灯具从电源断开到完全熄灭的时间，由电容数量和电容组数量决定，数量越多，时间越长。正常情况下，二个电容组，每个电容组由八个电容并联组成，熄灭时间大约为五秒，这个时间够人们的眼睛慢慢适应并走到室内其它位置。
综上所述，本发明是一种方便好用的具有缓慢熄灯效果的LED灯。
附图说明
图1是本发明实施例的电路图；
具体实施方式
下面结合附图和典型实施例对本发明作进一步说明。
本发明包括变压器、整流器和LED灯，所述LED灯与数个电容组串联，所述电容组由数个电容并联组成。在图1中，设置有2个电容组串联，每个电容组由8个电容并联组成共16个电容，电容可依据不同LED的耗电流及所需延迟的时间来选择适当的型号、规格与数量，图1中的电容采用50V的470MF，市电220VAC通过变压整流后得到74.4VDC，市电断开后，由电容组供电至LED灯缓慢熄灭。

Claims (2)
