Description
一种LED筒灯
技术领域
[0001] 本实用新型涉及一种灯具，尤其是一种LED筒灯。 背景技术
[0002] 随着社会的发展，人们的环保意识也随之增强，而LED光源具有能耗低、寿命长和使用安全等特点，得到人们的青睐。对应地，现在市场上也出现了使用LED光源的筒灯，但现有的LED筒灯由于结构紧凑而且功率较大，散热问题成为其在市场上普及的主要障碍。
实用新型内容
[0003] 为了解决克服现有技术的缺点，并满足市场的需要，本实用新型提供一种改良了的散热结构的LED筒灯。
[0004] 本实用新型采用的技术方案可以描述为：
[0005] 一种LED筒灯，包括壳体和LED光源模组，所述壳体为多边形筒体，所述LED光源模组包括多段相互连接的电路板以及设在所述电路板上的LED单元，所述多段电路板设置在所述壳体的多段内侧壁上，所述壳体腔体内还设有光路处理模组，后部设有散热器。
[0006] 作为以上技术方案的一种改进，所述壳体为圆内接多边形。
[0007] 作为以上技术方案的一种改进，所述壳体的侧壁由金属材料弯折制成，或者由金属材料一体成型制成。
[0008] 作为以上技术方案的一种改进，所述壳体与所述散热器一体成型。
[0009] 作为以上技术方案的一种改进，所述电路板为金属基板。
[0010] 作为以上技术方案的一种改进，所述光路处理模组由内至外包括有反光板、散射导光板和柔光板。
[0011] 作为以上技术方案的一种改进，所述LED筒灯还包括套装在壳体上圆形外壳，所述外壳将所述光路处理模组压紧固定在壳体内。
[0012] 本实用新型的有益效果是：
[0013] 与现有设备相比，本实用新型所提出的LED筒灯使用多边形的壳体，LED模组布置在多边形的各条边上，这样就能使用硬质的金属基电路板，减少LED单元与散热器之间的热阻，增强系统的散热冗余能力，进而提高灯具的功率或延长产品的寿命，以满足市场的需要。另外，LED模组环绕布置在光路处理模组周围，光线通过其中的导光板、反射板和柔光板导出，不仅光通量损失小，而且光照柔和舒适。
附图说明
[0014] 图1为本实用新型的一个实施例的结构示意图。 具体实施方式
[0015] 如图1所示，本实用新型所提出新型LED筒灯包括了一个内圈是多边形的筒状壳体1，其在内侧壁上提供用于安装光源的多个安装平面11。此壳体1可以由单块金属材料弯折制成，也可以由多块金属材料焊接而成，甚至可以是由金属材料一体成型铸造而成。在此实施例中，壳体1采用多块铝板焊接而成的一个圆内接多边形筒体，并利用铝板焊接封住筒体的一端。
[0016] 本实用新型所提出的筒灯采用了一个LED光源模组2作为其光源，值得注意的是， 本实用新型的壳体1提供了多个安装平面11用于放置LED光源，这样LED光源模组2就可以采用散热更好的硬质金属基电路板21，比如铝基板，使LED单元22工作时产生的热量更好地传导到后方的壳体中，避免了使用圆形壳体时必须使用柔性电路板以顺从壳体弧度而导致热阻较大的弊端。对应此多边形结构，本实用新型所采用的LED光源模组2包括多块串联的电路板21，每一块电路板21上均设有多个LED单元22，所述电路板21顺次固定在所述安装平面11上，电路板21上的LED单元22朝向壳体1的轴线。
[0017] 为了加强灯具的散热能力，壳体1后方还设有散热器4，此散热器4为带有散热鳍片的铝制散热器。当然，此散热器4也可以是与壳体1 一体成型的铸造铝件，以进一步增强本产品的散热能力。
[0018] 为了进一步减小各部件接合面之间的热阻，生产时可以在电路板21和安装平面 11之间，壳体1和散热器4之间涂抹软性导热材料，比如导热硅脂。
[0019] 除此之外，本实用新型所提出的LED筒灯还包括有一套光路处理模组3，由内至外包括有反光板31、散射导光板32和柔光板33，光线通过被LED光源所包裹的反光板31反射，散射导光板32散射传导和柔光板33柔化后射出，不仅光通量损失小，而且光照柔和舒适。所述LED筒灯还包括套装在壳体1上圆形外壳5，所述外壳5将所述光路处理模组3压紧固定在壳体1内，并通过其上设置的弹簧夹将所述灯具固定在灯具的安装孔上。
[0020] 通过以上所描述的结构，LED筒灯工作时LED单元22所产生的热量可以通过金属基电路板板21传导到壳体1上，再经散热器4快速散发到空气中。
[0021] 与现有设备相比，本实用新型所提出的LED筒灯使用多边形的壳体，LED模组布置在多边形的各条边上，这样就能使用硬质的金属基电路板，减少LED单元与散热器之间的热阻，增强系统的散热冗余能力，进而提高灯具的功率或延长产品的寿命。
[0022] 以上所述只是本实用新型优选的实施方式，其并不构成对本实用新型保护范围的限制，只要是以基本相同的手段实现本实用新型的目的都应属于本实用新型的保护范围。
