Description

一种智能LED灯
技术领域
本实用新型涉及一种LED控制技术领域，具体是指一种能够实现多种亮度的LED灯控制电路。
背景技术
LED照明作为一种新型节能环保产品越来越受到人们的关注，随着技术的不段进步，在不久的将来，将有全面取代目前灯具市场上的高压钠灯、荧光灯、白炽灯、卤钨灯，节能灯等的趋势。现有小功率LED应用领域，通常用220V交流市电供电，电源电路中采用阻容降压方式得到所需电流电压，然后将多颗LED灯珠串/并联起来做成灯具产品。这种LED灯具供电电压固定，所有灯珠在同一线路中，因此只能有一种亮度，使用受到限制。实际上在很多场合，都需要对灯的亮度进行调节。例如在路灯的应用中，为了能进一步节能，在夜深人静没有人走动时微亮，当有人通过时则需要更一点。其它产品也同样有这样的需要。
实用新型内容
本实用新型需解决的问题是提供一种能够实现多种亮度的LED灯控制电路。
为解决上述问题，本实用新型采取的技术方案为：提供一种智能LED灯，包括电源控制电路和串/并联的LED灯珠组成的发光电路，所述电源控制电路至少具有一路直接供电给LED灯珠组成的发光电路使发光电路通电即亮，至少具有一路采用声控和/或人体红外感应的智能控制电路；所述智能控制电路将220V交流电整流滤波后输出给LED灯珠组成的发光电路正极，带有传感器的声控和/或人体红外感应控制电路通过三极管开关电路连接于发光电路负极。
相对于现有技术，本实用新型的有益效果在于：在同一灯具中采用多种控制方式使灯具具有多种亮度，灯具的使用更加方便、更加人性化，同时可节约在空闲时间内50％以上的电能。
附图说明
图1为本实用新型实施例电路组成示意图。
具体实施方式
下面结合附图对本实用新型作进一步的详细说明。
如图1所示，为本实用新型实施例电路组成示意图。该实施例中，所述的智能LED灯包括一路直接供电给第一路发光电路的控制电路，即图中虚线框内1内所示，该部分将220V交流市电经二极管D1-D4、电容C1、RC1、电阻R1组成的整流滤波电路后输出适合第一路发光电路的直流电压驱动第一路发光电路，第一路发光电路负极直接接地。这样只要打开电源开关，接通电源，所述LED灯即可发光照明。当然，该部分也可以用恒流源代替，直接由恒流源为第一路发光电路供电。
实施例中包括两路并联的智能控制电路，如图中虚线框2所示，该部分将220V交流市电经第二路整流滤波电路后输出第二路发光电路，该发光电路负极接智能控制电路。图中，虚线框2A内为声控电路，虚线框2A内为人体红外感应电路，二者并联，输出的控制信号均通过电阻R7接三极管Q1基极，三极管Q1集电极接地，射极接第二路发光电路负极。这样在对亮度需要较低时，只有第一路发光电路照明；而当人们活动频繁，需要较大的照明亮度时，声控电路或人体红外感应电路接收到这些信号则控制第二路发光电路发光照明，满足亮度要求。
以上实施例仅为本实用新型较佳的实施方案，在不脱离本实用新型构思前提下对其所做的任何微小变化及等同替换，均应属于本实用新型的保护范围。

Claims (2)
