Description

多面体LED灯具
技术领域
本发明属于照明灯具领域，特别是一种用于照明的LED灯具。
背景技术
LED发光二极管作为照明光源在灯饰领域已得到广泛应用。但现有的LED发光二极管作为照明光源存在有如下缺点：平面封装，LED作为点光源须通过透镜等方式来增强其发光角度，而通过透镜等方式增强的发光角度也大约只有160度，并且其发热量大，容易造成发光量衰减，且会影响使用寿命，而且单位瓦数的光通量一般在50～70流明。
发明内容
为了克服现有技术的不足，本发明提供一种多面体LED灯具，该多面体LED灯具具有多个面同时发光、发光角度大、发热量低、光强度衰减减小、使用寿命长等特点。
本发明解决其技术问题所采用的技术方案是：
多面体LED灯具，其特征在于其包括一多面体，所述多面体的各侧面及顶部安装有LED芯片。
作为本发明上述技术方案的改进，所述多面体的侧面及顶部涂有荧光粉。
上述多面体可采用八面体，在多面体上还可安装有灯罩；多面体安装在一基座上，基座上连接有连接螺丝。
本发明的有益效果是：本发明具有如下特点：多个面同时发光，发光角度可达270度以上，并且通过顶部LED芯片发出的光线可起到直射效果，发热量低，光强度衰减减小，使用寿命长；该灯具结构较简单，灯具维修简便，且单位瓦数的光通量可达到110流明。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的主视图；
图2是图1的俯视图。
具体实施方式
参照图1、图2，本发明公开的一种多面体LED灯具，包括一多面体1，该多面体1可以是如图所示的八面体，也可以是其它的多面体形状，在多面体1上安装有灯罩2，并且多面体1安装在一基座3上，基座3上连接有连接螺丝4，以便于将基座3及多面体1连接到对应的灯体上。在多面体1的各侧面及顶部安装有LED芯片5，在使用过程中多个面上的LED芯片同时发光，发光角度可达270度以上，并且通过顶部LED芯片发出的光线可起到直射效果，发热量低，光强度衰减减小，使用寿命长；该灯具结构较简单，灯具维修简便，且单位瓦数的光通量可达到110流明。
在多面体的侧面及顶部可以涂覆荧光粉，以增强灯具的性能。
