Description
一种大功率的LED天花灯
技术领域
[0001] 本实用新型涉及大功率节能型室内照明灯具，特别是涉及一种散热性能好的大功率LED天花灯。
背景技术
[0002] 与传统的照明灯具相比，LED天花灯不仅节能、环保、安全，而且使用寿命长，特别是发光效率高，无污染且光源色温近自然光，因此，LED天花灯普通被应用于室内照明场所。
[0003] 大功率LED天花灯主要包括壳体，光源模组，散热模组和驱动电源，光源模组安装在壳体和散热模组之间，光源模组和驱动电源连接，现有LED天花灯存在的不足是： [0004] LED为冷光源，但工作时仍会产生一定的热量，LED的工作温度一般应小于50度。有资料显示，当LED的工作温度达到55度时，其寿命就要减少一半。目前，市面常规大功率LED天花灯大都是通过在普通铝制散热柱中心有一个很大的空心槽。为了保证良好的散热效果，一般的大功率LED天花灯体积设计都比较大，这无形中增加了 LED天花灯的造价，但并没有有效的解决大功率LED天花灯发热量的问题。
[0005] 大功率LED芯片焊在铝基板线路上，整块铝基板下垫有高导热硅脂，并通过螺丝直接固定在散热模组上。此散热结构导致大功率灯板中心点温度积聚，至此采用该结构使天花灯所用LED单颗功率不高，LED单颗数量不多。散热问题严重影响到LED芯片的使用寿命。
实用新型内容
[0006] 本实用新型的目的是提供一种解决铝基板中心点温度积聚现象、具有功率大、散热强、体积小、节能环保、且寿命长的大功率的LED天花灯。
[0007] 为了实现上述目的，本实用新型设计出一种大功率的LED天花灯，它包括壳体、光源模组和散热模组，光源模组位于壳体与散热模组之间，所述壳体包括外壳、内壳和内环；所述光源模组包括铝基板、安装在铝基板上的LED芯片、铝片、单颗透镜和透镜架，铝片、单颗透镜和透镜架安装在壳体和LED芯片之间，光源模组下方安装有散热模组。
[0008] 所述的壳体的外壳设有至少个的卡簧，所述卡簧安装在外壳上设置的固定槽内。
[0009] 所述的光源模组的铝基板通过螺丝直接固定在散热模组正上方。
[0010] 所述的散热模组位于铝基板下方。
[0011] 所述的散热模组由航空铝材制作，散热器中心为实心，放射状散热鳍片设置于实心铝柱上，这样可以提高了散热模组的散热效果。在散热模组一侧设有一个贯通的开口槽。散热模组前端与壳体后部相匹配。铝基板直接固定在散热模组，铝基板与散热模组完美结合，有效的提高了 LED芯片的散热效果。
[0012] 本实用新型大功率的LED天花灯由壳体、光源模组、散热模组和驱动电源构成，既有效解决散热问题，又能增加光照度的一种大功率LED天花灯，以克服上述已有技术的不足。在铝基板中央放置一颗LED芯片，其余LED芯片均匀分布于铝基板边缘。本实用新型大功率的LED天花灯透镜通过相同的光学配光设计，有效提高了 LED天花灯的应用效率，克服了 LED光斑产生杂光的现象。

[0013] 图I是本实用新型大功率的LED天花灯立体结构示意图；
[0014] 图2是图I的分解结构示意图。
具体实施方式
[0015] 为了便于本领域技术人员的理解，下面将结合具体实施例及附图对本实用新型的结构原理作进一步的详细描述。
[0016] 如图I、图2所不,一种大功率的LED天花灯,它包括壳体、光源模组和散热模组,光源模组位于壳体与散热模组之间，所述壳体包括外壳I、内壳2和内环3 ;所述光源模组包括铝基板8、安装在铝基板上的LED芯片7、铝片4、单颗透镜5和透镜架6，铝片4、单颗透镜5和透镜架6安装在壳体和LED芯片之间，光源模组下方安装有散热模组9。
[0017] 如图I、图2所示，所述的壳体的外壳设有2个的卡簧10，所述卡簧安装在外壳上设置的固定槽内。在外壳上也可以设置有3个的卡簧10。可根据应用需要合理设置卡簧的数量。
[0018] 如图2所示，所述的光源模组的铝基板8通过螺丝直接固定在散热模组9正上方。
[0019] 如图2所示，所述的散热模组9位于铝基板8下方。
[0020] 如图I、图2所示，所述的散热模组9由航空铝材制作，散热器中心为实心，放射状散热鳍片置于实心铝柱上，在散热模组一侧设有一个贯通的开口槽。
[0021] 本实用新型大功率的LED天花灯将壳体、光源模组和散热模组有效结合，散热模组为航空铝材制作，解决铝基板中心点温度积聚现象，具有功率大，散热强，体积小，且寿命长等特点。
[0022] 以上所述，仅为本实用新型的较佳实施例而已，并非对本实用新型作任何形式上的限制；凡本行业的普通技术人员均可按说明书附图所示和以上所述而顺畅地实施本实用新型；但是，凡熟悉本专业的技术人员在不脱离本实用新型技术方案范围内，可利用以上所揭示的技术内容而作出的些许更动、修饰与演变的等同变化，均为本实用新型的等效实施例；同时，凡依据本实用新型的实质技术对以上实施例所作的任何等同变化的更动、修饰与演变等，均仍属于本实用新型的技术方案的保护范围之内。
