Description

新型LED照明灯
技术领域
本实用新型属于LED照明灯装置领域，尤其是一种新型LED照明灯。
背景技术
目前，通用的LED照明装置的每一个LED灯都是通过一个驱动电路来发光的，整体的LED照明装置又设置有一个总的电源装置。这种结构的LED照明装置存在的问题是：1、结构复杂，由于除了LED灯之外还需要大量的驱动装置，因此体积很大；2、由于大量驱动装置的存在，功耗很大；3、成本高；4、由于电路结构复杂和体积大的原因，限制了LED照明装置的应用领域。
实用新型内容
本实用新型的目的是提供一种电路结构简单、功耗小、成本低廉而且应用范围广泛的一种新型LED照明灯。
本实用新型的技术方案是：新型LED照明灯，包括壳体，其特征是在壳体内设置有LED灯板、恒流装置和整流桥电路，在LED灯板上设置有一列或数列并联连接的LED灯列，每一列LED灯列由数个LED灯串联连接组成，相互并联的LED灯列的一端连接有恒流装置，另一端连接整流桥电路的一个输出端，恒流装置的另一端与整流桥电路的另一个输出端相连，整流桥电路的输入端延长到壳体的外部。
所述的LED灯为表贴灯或直插LED灯或LED管芯。
所述的LED灯板为PCB板。
本实用新型的效果是：新型LED照明灯，在壳体内设置有LED灯板、恒流装置和整流桥电路，在LED灯板上设置有一列或数列并联连接的LED灯列，相互并联的LED灯列的一端连接有恒流装置，另一端连接整流桥电路的一个输出端，恒流装置的另一端与整流桥电路的另一个输出端相连，整流桥电路的输入端延长到壳体的外部。整流桥电路和恒流装置的组合，能够使LED照明灯在没有驱动装置的情况下，正常工作。由于本实用新型减少了以往LED照明装置存在的大量驱动电路，能够减小LED照明装置的体积、降低功耗和制作成本，与现有的LED照明装置相比，同等条件下，成本降低30％，功耗降低40％。由于体积的减小，应用范围也有了很大扩展。
