Description

限流LED电路
技术领域
本实用新型涉及LED技术领域，具体涉及一种LED电路。
背景技术
LED(Light-Emitting-Diode中文意思为发光二极管)是一种能够将电能转化为可见光的半导体，它改变了白炽灯钨丝发光与节能灯三基色粉发光的原理，而采用电场发光。据分析，LED的特点非常明显，寿命长、光效高、无辐射与低功耗。LED的光谱几乎全部集中于可见光频段，其发光效率可超过150lm/W。
所以，在可以预见的未来，体积小、耗电量低、使用寿命长的LED终将取代其它照明光源，但由于LED功率低，当供电电源不稳定时，过大的电流容易烧毁LED。
实用新型内容
有鉴于此，为了解决上述问题，为此，本实用新型提出一种限流LED电路。
限流LED电路，包括电源电路和LED，所述电源电路和LED之间串联有限流电路。
所述限流电路由限流电阻构成。
本实用新型的限流LED电路，在电源电路和LED之间串联有限流电路，当电流过大时，可起到限流作用，防止烧毁LED。
附图说明
图1示出了限流LED电路的结构示意图。
具体实施方式
以下将参照附图，对本实用新型的优选实施例进行详细的描述。
参见图1，限流LED电路，包括电源电路和LED，所述电源电路和LED之间串联有限流电路。所述限流电路由限流电阻构成。

Claims (2)

1.限流LED电路，包括电源电路和LED，其特征在于：所述电源电路和LED之间串联有限流电路。
2.如权利要求1所述的限流LED电路，其特征在于：所述限流电路由限流电阻构成。
