Description

双面透光的LED灯具 技术领域
本发明涉及LED灯具领域技术，尤其是指一种双面透光的LED灯具。
背景技术
发光二极管灯具，亦称LED灯具，以其高效、节能、长寿、小巧等技术特点，正在成为新一代照明市场的主力产品，且有力地拉动环保节能产业的高速发展。
为了达到更好的装饰效果，现有的LED灯具例如一些庭院灯，通常被设计为双面发光的形式，即一部分光从LED灯具向下透射出，另一部分光从LED灯具向上透射出。为了能够实现两面发光的目的，现有的LED灯具通常对LED灯盘做改进，即在LED灯盘之基板的上下两面均设置有多个LED灯体，如此利用对应的LED灯体发出的灯光朝向相应的方向直接透射出而现实双面发光。
上述现有的LED灯具结构，虽可实现双面发光的功效，确实具有进步性，但是在实际使用时却发现其自身结构和使用性能上仍存在有诸多不足，造成现有的LED灯具在实际应用上，未能达到最佳的使用效果和工作效能，现将其缺点归纳如下：首先，由于其需要在基板的上下表面均设置有多个LED灯体，如此使得单个产品制作采用的LED灯体数量较多，从而增加了产品的制作成本，并且也使得产品更加耗能；其次，由于位置受到限制，使得散热器难以甚至无法装配，从而不能对LED灯盘进行很好地散热，影响产品的使用寿命。
发明内容
有鉴于此，本发明针对现有技术存在之缺失，其主要目的是提供一种双面透光的LED灯具，其能有效解决现有之LED灯具采用在基板上下表面设置LED灯体的方式存在制作成本高并且使散热器难以甚至无法装配的问题。
为实现上述目的，本发明采用如下之技术方案：
一种双面透光的LED灯具，包括有灯座、散热器以及LED灯盘；
该灯座上设置有开口朝下的容置空间，灯座的顶部设置有连通该容置空间的透光孔，该透光孔中设置有第一透光镜；
该散热器和LED灯盘均固设于前述容置空间中，该散热器上设置有第一通孔，该第一通孔与前述透光孔正对连通；
该LED灯盘包括有基板以及设置于基板表面上的多个LED灯体，该基板的底面抵于散热器上，该基板上设置有第二通孔，该第二通孔与前述第一通孔正对连通；
以及，该灯座上固设有第二透光镜，该第二透光镜封盖住前述容置空间的开口，且该第二透光镜的背面上设置有用于将部分灯光反射而从第一透光镜向外透射出的反射面。
作为一种优选方案，所述第二透光镜为PS材质。
作为一种优选方案，所述反射面为磨砂面。
作为一种优选方案，所述灯座包括有灯壳以及固设于该灯壳内的主体，前述容置空间于主体上凹设形成；该透光孔包括有第一透光孔和第二透光孔，该第一透光孔设置于灯壳上，该第二透光孔设置于主体上，该第一透光孔和第二透光孔彼此正对连通，该第一透光镜的周缘夹设于灯壳和主体之间，且该第一透光镜向外露出第一透光孔。
作为一种优选方案，所述主体通过一环盖与灯壳固定连接，该第一透光孔的周缘向内折弯形成有勾部，该勾部与环盖的内周缘卡合，该主体通过螺丝与环盖的外周缘固定连接。
作为一种优选方案，所述灯壳呈伞状。
作为一种优选方案，所述散热器包括有中空筒体以及于中空筒体侧面间隔延伸出的多个固定板，该多个固定板通过螺丝与灯座固定连接，该中空筒体的侧面以及固定板的侧面均向外辐射出有多个散热鳍片。
作为一种优选方案，所述基板通过螺丝固定于散热器上，该基板呈圆环状，该多个LED灯体均布于该基板的表面上，该第二通孔呈圆形。
作为一种优选方案，所述容置空间的开口周缘下凹形成有台阶面，该第二透光镜的周缘抵于该台阶面上，该第二透光镜通过螺丝与灯座固定连接。
作为一种优选方案，进一步包括有环形灯罩，该环形灯罩为玻璃材质，该环形灯罩的顶部抵于灯座的底部上，该环形灯罩通过固定片与灯座固定连接，该固定片的一端通过螺丝锁固于灯座上，该固定片的另一端卡住环形灯罩的顶部内侧缘。
本发明与现有技术相比具有明显的优点和有益效果，具体而言，由上述技术方案可知：
通过于第二透光镜的背面上设置有反射面，一部分光从第二透光镜直接向下透射出，另一部分光利用反射面进行反射后，依次经过第二通孔和第一通孔后从第一透光镜向上透射出，从而实现双面发光，取代了传统之在基板上下表面均设置LED灯体的方式，本发明能够有效减少LED灯体的使用数量，从而降低了产品的制作成本，也使得产品更加节能；其次，由于本产品仅于基板的一表面设置LED灯体，使得其可轻易地实现散热器的装配，不会受到位置的限制，产品的组装更加方便，并可对LED灯盘进行很好地散热，从而利于延长产品的使用寿命。

以及，该灯座10上固设有第二透光镜50，该第二透光镜50封盖住前述容置空间101的开口，且该第二透光镜50的背面上设置有用于将部分灯光反射而从第一透光镜40向外透射出的反射面51；在本实施例中，该第二透光镜50为PS材质，该第二透光镜50呈圆形板状，该反射面51呈环形，并且该反射面51为磨砂面，不以为限，只需能够反射部分灯光使部分灯光从第一透光镜40透射出即可；以及，在本实施例中，该容置空间101的开口周缘下凹形成有台阶面104，该第二透光镜50的周缘抵于该台阶面104上，该第二透光镜50通过螺丝60与灯座10的主体12固定连接。
此外，进一步包括有环形灯罩70，该环形灯罩70为玻璃材质，该环形灯罩70的顶部抵于灯座10的底部上，该环形灯罩70通过固定片80与灯座10固定连接，该固定片80的一端通过螺丝90锁固于灯座10上，该固定片80的另一端卡住环形灯罩70的顶部内侧缘，如此使得环形灯罩70组装后无螺丝外露，从而使得产品外观更加美观。
详述本实施例的组装过程如下：
组装时，首先，将环盖13置于灯壳11内部，使第一透光孔102的周缘向内折弯形成有勾部111，利用勾部111勾住环盖13的内周缘，如此使得环盖13与灯壳11固定连接；接着，将散热器20置于容置空间101内，使用螺丝23穿过主体12与固定板22螺合固定连接，如此将散热器20固定于容置空间101内；接着，将第一透光镜40穿过环盖13向外露出第一透光孔102，将主体12抵接于环盖13上，使得第一透光镜40的周缘夹于环盖13与主体12之间，并通过螺丝14穿过主体12与环盖13螺合连接，组合形成灯座10，同时也将第一透光镜40固定于灯座10上；然后，将LED灯盘30的基板31抵于散热器20的表面上，并通过螺丝33将基板31锁固于散热器20上；接着，将第二透光镜50的周缘抵于台阶面104上，并使用螺丝60将第二透光镜50固定于灯座10的主体12上；然后，将环形灯罩70的顶部抵于灯座10的底部上，并通过螺丝90将固定片80锁固于灯座10的主体12上，同时使得固定片80卡住环形灯罩70的顶部内侧缘，从而实现了将环形灯罩70固定于灯座10上。
使用时，将LED灯盘30连接外部电源而使得LED灯盘30发光，其发出的光大部分经第二透光镜50向下透射出，一部分光经过反射面51反射后，依次经过第二通孔301和第一通孔201后从第一透光镜40向上透射出，从而实现了两面发光。
本发明的设计重点在于：通过于第二透光镜的背面上设置有反射面，一部分光从第二透光镜直接向下透射出，另一部分光利用反射面进行反射后，依次经过第二通孔和第一通孔后从第一透光镜向上透射出，从而实现双面发光，取代了传统之在基板上下表面均设置LED灯体的方式，本发明能够有效减少LED灯体的使用数量，从而降低了产品的制作成本，也使得产品更加节能；其次，由于本产品仅于基板的一表面设置LED灯体，使得其可轻易地实现散热器的装配，不会受到位置的限制，产品的组装更加方便，并可对LED灯盘进行很好地散热，从而利于延长产品的使用寿命。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
