Description
—种具有多层散热结构的LED射灯
【技术领域】
[0001] 本实用新型涉及LED射灯技术领域，尤其涉及一种具有多层散热结构的LED射灯。【背景技术】
[0002] 传统卤素灯杯耗能高、寿命短，在全球资源紧张的大环境下，LED射灯耗能低、寿命长且不含对环境有害的Pb，Hg等有害元素，是替代传统卤素灯杯的新型节能灯具。目前LED射灯散热主体由于外形规格的制约，在有限的体积内难以增加有效散热面积，从而导致散热性能不佳。
【实用新型内容】
[0003] 本实用新型的目的在于有效克服上述技术的不足，提供一种具有多层散热结构的LED射灯，该具有多层结构的LED射灯的内部采用多层散热的方式，使得散热性能得到了极大的提升。
[0004] 本实用新型的技术方案是这样实现的:它包括灯头、多层散热主体、铝基板以及透镜，所述多层散热主体具有上、下两个腔体，所述铝基板通过螺丝固定于多层散热主体的上腔体内，所述透镜盖在上腔体的开口处，其改进之处在于:所述多层散热主体的上腔体内部设有有规则排列的复数个散热鳍片，且多层散热主体的外表面上设置有与上腔体连通的条状的散热孔；
[0005] 上述结构中，所述透镜的外缘上、对应于散热鳍片的位置上设有复数个散热孔；
[0006] 上述结构中，所述多层散热主体为圆台形结构；
[0007] 上述结构中 ，所述多层散热主体的下腔体内设有驱动电源，并且该驱动电源与铝基板电性连接；
[0008] 上述结构中，所述灯头的一端设置在下腔体内，所述下腔体内部的驱动电源连接到灯头的电源输入端；
[0009] 上述结构中，所述灯头为G5.3灯头、⑶10灯头、E14灯头，E27灯头其中任意一种。
[0010] 本实用新型的有益效果是:本实用新型的多层散热主体的结构，在保证产品外形美观的同时，采用了内部多层的散热结构，同时透镜上也具有相匹配的散热孔，使得本实用新型上下通透，增加了散热面积和空气的对流，使得本实用新型的散热性能得到了极大的提升，另外散热主体的下腔体为通用型的，可以匹配的灯头有G5.3灯头、⑶10灯头、E14灯头，E27灯头，通过更换灯头就能达到不同产品的要求。
【附图说明】
[0011] 图1为本实用新型的爆炸示意图；
[0012] 图2、图3、图4为本实用新型相匹配的灯头的立体示意图。
【具体实施方式】[0013] 下面结合附图和实施例对本实用新型作进一步的描述。
[0014] 参照图1所示，为本实用新型揭示的一种具有多层散热结构的LED射灯的第一具体实施例，在本实施例中，该LED射灯包括灯头10、多层散热主体20、铝基板30以及透镜40，并且灯头10采用GUlO灯头，多层散热主体20为圆台形结构，具有上、下两个腔体，铝基板30通过螺丝301固定在上腔体内，铝基板30上设有LED光源302，灯头10的一部分设置在多层散热主体20的下腔体内，并且下腔体内设有驱动电源(图中不可见)，该驱动电源的一端连到灯头10的电源输入端101，另一端则连到铝基板30上，以对铝基板30上的LED光源302提供电能。多层散热主体20的上腔体内部设有复数个散热鳍片201，如图1所述，散热鳍片201有规则的排列在多层散热主体20的上腔体的内壁上，形成类似于孔洞的结构，多层散热主体20的外表面上还设有与上腔体连通的条状的散热孔202，通过此种结构，LED光源302发光时产生的热量，多层散热主体20即可通过散热鳍片201向空气中散发，另外，透镜40的外缘上、对应散热鳍片201的位置上设有复数个散热孔401，这种结构的设计使得多层散热主体20上下通透，增加了空气对流，进一步的提高了 LED射灯的散热效率。
[0015] 在上述结构中，由于本实用新型的多层散热主体20的下腔体为通用型的，可以匹配不同的灯头，参照图2、图3所示，即为灯头的两种具体形式，其中，图2中为E27灯头50，图3中为G5.3灯头60，图4中为E14灯头70，这两种灯头均可直接与多层散热主体20进行匹配。
[0016] 本实用新型在保证产品外形美观的同时，采用了内部多层的散热结构，同时透镜上也具有相匹配的散热孔，使得本实用新型上下通透，增加了散热面积和空气的对流，使得本实用新型的散热性能得到了极大的提升。
[0017] 以上所描述的仅为本实用新型的较佳实施例，上述具体实施例不是对本实用新型的限制。在本实用新型的技术思想范畴内，可以出现各种变形及修改，凡本领域的普通技术人员根据以上描述所做的润饰、修改或等同替换，均属于本实用新型所保护的范围。
