应用例三
以上应用例是指灯架来完成整灯的散热, 在本应用例中, 所述灯罩采用散 热性能好的铝板制成, 灯罩的顶部与 PCB板的形状相符, 且位于灯罩的内部, 并紧密贴合于灯罩顶部, 未设有散热器, 所述 LED照明装置通过所述灯罩进行 散热。 原理和灯架整体散热的思路一致, 以下以工矿灯为例来说明。
工矿灯是一种广泛用于工厂的车间、矿井作业面以及仓库的照明设备, 由于 这些场所的照明灯具通常安装位置较高, 而且对亮度和光线照射方向具有特殊 要求, 所以工矿灯的功率通常较高, 光线照射角度较小。 传统工矿灯通常采用白炽灯、 钨灯或高压气体放电灯, 这些灯具普遍存在 能耗较高, 使用寿命较短的问题。 而 LED照明灯具具有体积小、 寿命长、 环氧 树脂封装、 可承受高强机械沖击和震动、 不易破碎等特点, 不仅节能、 维护费 用低, 并且其配光效果可以根据用户需求而设计。 现有 LED工矿灯通常包括聚 光罩、 LED颗粒、 电路板、 散热器、 电源箱和灯杆, LED颗粒产生的热量通过散 热器进行散热, 通常散热器体积较大, 且跟电路板接触不够充分而导致散热效 果较差。 本实例设计了一种散热性能优越、 筒易轻便的 LED工矿灯, 这种工矿灯利 用一体化制成的灯罩进行散热, 电源和光源相互隔离; 同时在 LED光源前增加 了配光透镜, 根据工矿灯的照明场所, 可通过设计不同配光效果的透镜来决定 LED工矿灯的照明效果。
请参阅图 1 3 , —种 LED工矿灯, 其包括透镜组、 LED颗粒、 电路板、 灯罩 304、 电源、 电源壳 302和灯杆 301。 所述 LED颗粒设置在所述 PCB板上, 所述透镜组边缘贴合在 PCB板的边缘, 且罩于 LED颗粒之上, 用于调整 LED光源出射光的分布; 所述灯罩呈喇叭形, 采用高散热性能的材料制成(比如由厚度在 0.5mm至 5mm, 含铝 95%以上的高纯度铝板材拉深后一体制成, 所述灯罩的导热系数大 于 200W/(m*K) ), 灯罩顶部与 PCB板形状相符, 且开设有多个开孔, 用于固定 PCB板; 所述 PCB板位于灯罩内部, 并紧密贴合在灯罩顶部; 所述电源置于灯罩之上, 并贴合在灯罩顶部; 所述电源壳套设在电源外, 且电源壳内部和外部设置有加强筋, 既有效固定 了电源, 又增加了电源的散热面积;
所述灯杆通过电源壳之上的转接头连接;
所述电源壳和所述灯罩贴合处设置有装饰圈 303。
显然, 本领域的技术人员可以对发明进行各种改动和变型而不脱萬本发明的精 神和范围。 这样, 倘若本发明的这些修改和变型属于本发明权利要求及其等同 技术的范围之内, 则本发明也意图包含这些改动和变型在内。
