Description

电子交通信号灯
本实用新型涉及交通信号灯,尤其是电子交通信号灯。
中国专利CN2083239U公开了“新型电子交通信号灯。它采用单色发光二极管为发光器件,由降压变压器,全波整流器,稳压电路为单色发光盘提供工作电压。其不足之处是电路相对复杂,并未充分利用现有交通信号机及相关设备,无形中增加了技术难度和成本;另外,因上述发光器件角度不可调,而发光二极管射角较小,故导致交通信号灯视角效果不佳。
本实用新型的目的在于提供一种电路简单,发光盘角度可调且可充分利用现有交通信号机的稳压、变压功能的电子交通信号灯。
一种电子交通信号灯,包括遮光罩、面罩玻璃、发光盘和后灯壳,发光盘通过调节螺杆设于面罩玻璃与后灯壳之间,发光盘上的发光二极管分组串联后并联,上述发光盘前端设有整流电路。
如上所述的信号灯,整流电路由全波整流桥堆和电容器组成。
如上所述的信号灯,发光二极管呈圆形均布于发光盘上。
本实用新型利用了发光二极管工作可靠性强的特点,将发光盘上的二极管分组串联后并联,且仅设一整流电路。既充分利用了现有交通信号机稳压、变压功能,又避免了重复设计,使电路得以简化,从而降低了成本和投入;其次,发光盘可通过调节螺杆调节其角度,从而克服了发光二极管射角小使得视角效果不佳的问题。另外,本实用新型还具有结构简单、造价低、安装和维修方便的优点。
以下结合附图对本实用新型予以详述。
图1为实施例的剖视图。
图2为实施例的电路图。
参照图1-2,本实施例包括遮光罩1、面罩玻璃2、发光盘4和后灯壳5,发光盘通过后灯壳上的调节螺杆3设于面罩玻璃和后灯壳之间。发光盘上的发光二极管呈圆形均布。上述的发光二极管D1-Dn分组串联后并联,且串联电路中设有分压电阻R,并在上述发光盘前端设有由全波整流桥堆和电容器C构成的整流电路。
