Description

一种太阳能LED庭院灯
技术领域
本发明涉及一种太阳能LED庭院灯。
背景技术
现有的太阳能LED庭院灯存在以下不足：一是太阳能电池板对太阳能的收集能力较低；二是LED光源散热效果不好，影响使用寿命；三是LED内的环氧树脂容易受紫外线的干扰，长时间工作后树脂慢慢变得混浊，影响发光效率。
发明内容
本发明的目的就是针对上述情况提供一种太阳能利用率高，使用寿命长，发光效率高的太阳能LED庭院灯。本发明的目的可通过以下方案来实现：一种太阳能LED庭院灯，包括灯头、灯架和设置于灯架内部的蓄电池，蓄电池与灯头电连接，灯架的上端通过旋转连接件连接有灯头，使得灯头能水平360度旋转，旋转连接件的下端固定设有太阳能电池板，太阳能电池板与蓄电池电连接，其特征是在灯头里设有LED光源组件，在灯头内表壁上设有聚光层，聚光层能够汇聚LED光源组件的光线，使其照明更远、理清晰，灯头的开口处密封固定设有透明玻璃罩，该透明玻璃罩能够保护LED光源组件免遭风吹雨淋的侵袭，所述太阳能电池板包括上层绝缘基板和下层绝缘基板，在上层绝缘基板和下层绝缘基板之间设有透明导电层和薄膜电池板，上层绝缘基板的上表面设有若干个凸起，所述薄膜电池板与下层绝缘基板之间设有背面电极层，这种结构的太阳能电池板增加了单块电池的太阳光的吸收面积，提高太阳光的吸收效率，增强了电池板的光照度，提高了光电转换效率；所述LED光源组件包括铝基板和LED，所述铝基板为长方形，由铜箔线路板，导热绝缘层和铝板三层组成，上层为铜箔线路板，底层为铝板，导热绝缘层处在铜箔线路板和铝板之间，铝基板上设有若干个碗形槽，碗形槽的底部处在铝板上，所述LED包括芯片和荧光粉，芯片固定在碗形槽底面的铝板上，荧光粉设在芯片上，铜箔线路板与芯片通过金钱连接。由于芯片直接安装在铝板上，无需通过导热绝缘层，而是直接通过铝板直接散热，另外，铜箔线路板不仅导电，还能通过连接芯片的金线散发一部分热量，大大提高了LED的散热效果，延长了LED的使用寿命，碗形槽的设置可以加大LED的照射角度，不再使用环氧树脂，使得长时间工作也不会影响LED的发光效率。本发明具有太阳能利用率高，使用寿命长，发光效率高等特点。
