技术领域
本实用新型涉及LED路灯控制领域,具体涉及的是采集LED的温度后利用电路控制LED路灯的使用功率,还能进一步的实现对夜间使用的路灯做使用功率的调整。
背景技术
近年来,我国的路灯建设取得了飞速的发展,道路照明质量不断提高,高强度气体放电灯被广泛使用,对现代化城市建设起了很大作用,但是随之而来的是能耗的大幅度提高,特别是近年来能源价格大幅度提升,使电力耗费成为负担。在全球都在提倡绿色照明的时代,路灯的节能必然成为一种趋势。
目前,我国照明用电量占总用电量的13%左右,其中道路照明占整个照明用电量的25%~30%,因此道路照明节能具有很大的潜力和空间。目前道路照明使用最多的是高压钠灯,这种光源存在显色性差、启动时间长、耗电量高、发热量大等缺点,需要发展新的更节能的道路照明光源。大功率高光效LED是近年来国内外快速发展起来的新光源,它具有光效高(≥901m/W(1WLED))寿命长(30000~50000h)、耐震动不易损坏,瞬时启动、无污染等优点,白光LED是普通照明和道路照明的理想光源,因此发展LED路灯具有重要的节能意义。
而目前制约LED路灯发展的最大阻碍是LED灯的散热问题,故本发明人潜心研究,以期解决LED灯的散热问题。

还包括一时间控制电路,该时间控制电路与主控电路连接,主控电路接受时钟电路信号并控制功率调节电路输出信号控制LED灯的使用功率。
所述的温度检测电路主要包括一温度取样电路和一温控电路,而温度取样电路采集LED灯的温度信号,经温控电路输入至主控电路。
所述的主控电路主要包括输入电路、过压保护电路、整流电路、脉宽调制电路、振荡电路、滤波电路和直流输出电路。
采用上述方案的LED路灯节能控制电路,可以实时侦测光源的温度,从而达到监控和保护LED灯的目的,本实用新型还具备了定时功能,可以设定开启时间,和下降功率的时间,在深夜将灯功率减到实际功率的一半,从而实现节能的效果。
