Description

超薄对流散热投光灯 技术领域
本发明涉及照明灯具领域，尤其涉及一种超薄对流散热投光灯。
背景技术
投光灯主要用于单体建筑外墙照明、大楼内光外透照明、绿化景观照明、广告设施照明等室外场合，因此对于投光灯的防水性能要求较高。现有的投光灯大多数是采用螺丝将灯体与透镜连接起来，这样做在潮湿地区或者下雨的天气容易导致投光灯进水，寿命减少，影响照明效果。并且目前大多数的投光灯灯体较厚，占据的空间较大，不易安装，在高空安装时容易发生事故。
发明内容
为解决现有的技术问题，本发明提供了一种超薄对流散热投光灯。
本发明具体内容如下：一种超薄对流散热投光灯，包括PC罩、铝基板、散热主体、光源、支架和三芯线，所述散热主体正面中部设有安装空腔，安装空腔设有第一外壁，所述光源固定在铝基板上，所述铝基板通过铝 基板固定螺丝固定在安装空腔底部；所述PC罩大小与安装空腔大小相适应，PC罩与安装空腔通过PC罩螺丝连接；所述支架通过支架固定螺丝活动安装在散热主体两侧；所述安装空腔底部设有通孔，三芯线通过所述通孔，其中三芯线的地线通过地线螺丝固定。其中，PC罩采用光学级高透光抗UV耐腐蚀的PC材料，透光率高达90％以上，辅以独特的配光设计，能够有效地把光利用起来；将铝基板、光源等设置在散热主体的安装空腔中，可有效利用散热主体的空间，减少灯具的体积和厚度。
进一步的，所述安装空腔内设有第二外壁，第二外壁位于第一外壁内，第二外壁的大小与铝基板大小相适应，第二外壁与第一外壁形成U型凹槽，所述PC罩内部设置一圈挡板，PC罩与散热主体相连时，PC罩的外边位于安装空腔第一外壁外，挡板位于U型凹槽之间。挡板位于U型凹槽之间，在水汽从外部进入灯具内部时需要通过PC罩的外边、第一外壁、挡板和第二外壁，与原先仅有PC罩的外边和第一外壁相比相当于增加了二道防水屏障，防水效果更加优良，且有利于安装时的定位。
进一步的，还包括胶圈，所述胶圈的大小与所述U型凹槽大小相适应，胶圈设置于U型凹槽内，胶圈未与散热本体接触的一面上设有凹槽，所述挡板位于胶圈的凹槽中。在安装时，可使挡板与U型凹槽之间连接紧密不留缝隙，能够取得更加优良的防水效果。胶圈可采用耐候性好的硅胶材质。
进一步的，所述胶圈与散热本体接触的外表面设置有凸起。采用三面凸 边的设计能够使胶圈与U型凹槽和散热本体连接更加紧密，并且起到有效的防水作用。
进一步的，还包括盖板，所述盖板与散热主体正面的规格相适应，盖板通过盖板固定螺丝与散热主体相接。在整个灯体外添加盖板，不仅使灯具结构工整美观，而且给灯具增加一重防水保护罩，起到更加有效的防水作用。
进一步的，还包括电线堵头，所述电线堵头设置在散热主体上。电线堵头可采用PG堵头，采用电线堵头固定电线，使电线防水防尘，将电线堵头设置在散热主体上可使电线与光源的连接更加安全并且节省空间。
进一步的，散热主体的背面设置有一堵头安装槽，所述堵头安装槽位于散热主体内部，所述堵头安装槽倾斜设置在散热主体上，倾斜角度为0-90度。将电线堵头设置在散热主体内能够更加有效地利用空间，在实际应用中，散热主体除了安装空腔以外还有一部分空间，可将堵头安装槽设置在这一部分空间中；堵头安装槽与散热主体间可以呈现一个角度，此角度可根据具体情况设置，如堵头安装槽位于散热主体正下方时，该角度为0度；堵头安装槽与散热主体垂直时倾斜角度为90度；堵头安装槽倾斜设置时，角度为0-90度之间。当堵头安装槽倾斜的时候，不仅能够使散热主体的空间得到充分利用，而且电线堵头倾斜设置在散热主体上，在遇到下雨或其他情况时能够有效地防止水分侵蚀电线堵头，且将电线堵头安装在散热主体内能够使结构更加简洁美观。
本发明的有益效果：采用这样的结构后，灯具结构美观简洁，空间利用率高，占据空间小，防水性能大大增加。
