Description
全方位高效散热LED路灯
技术领域
[0001] 本实用新型涉及一种LED路灯，具体说是一种全方位高效散热的LED路灯。背景技术
[0002] LED作为一种环保、节能、使用寿命长、发光效果好的新型照明光源，已经广泛用于各种道路照明使用。LED灯源为冷光源，工作时本身不产生热量，但电流流经LED的PN节时产生电阻热依然会使LED灯源升温，LED灯源在高温环境下工作易老化、光衰快，使用寿命短，因此解决LED灯源散热问题成为延长LED路灯使用寿命的关键问题。[0003] 传统的LED路灯主要通过散热片散热，如专利号为200720028083. 0公开的一种平板LED路灯，采用路灯机架上固定的LED散热片和电源散热片分别对LED发光腔体散热和对电源散热，LED散热片单边散热，散热效果差，发光腔内温升依然较高，且电源单独配备电源散热片，生产成本高，制作工艺复杂。
[0004] 现有LED路灯利用LED路灯发光腔与外部空气连通进行散热，如专利号为200710031037. 0公开的大功率LED路灯灯具，除了采用灯具背部散热片对发光腔进行散热，还利用发光腔内设一根或一组热管连接LED路灯灯座将腔内热量移出，相比传统只采用单边散热片散热的LED路灯，散热效果有很大的提高，但其不足之处在于：发光腔内与外部空气连通，防虫、防尘效果差，影响LED路灯的照明效果，如在发光腔与外部空气连通开口处设置呼吸器或隔网，路灯长期使用，呼吸器的活性炭或隔网吸附灰尘须经常更换，使用成本高，维修、更换不便，不适合路灯照明使用。
发明内容
[0005] 为了解决现有技术中封闭式LED路灯发光腔单独采用散热片散热，散热速度慢、效果差，LED易老化、光衰快，使用寿命短，或LED路灯采用热管将发光腔热量移出散热，防虫、防尘效果差，影响LED路灯照明效果，若采用活性碳呼吸器或隔网防护，使用成本高，维护不便等不足，本实用新型的目的是提供一种结构紧凑，生产制作方便，发光腔密闭防虫、防尘，路灯照明效果好，且发光腔全方位立体散热，散热速度快、效果好，LED工作环境好，使用寿命长的全方位高效散热LED路灯。
[0006] 为了达到上述目的，本实用新型采用的技术方案是：全方位高效散热LED路灯，包括灯体、散热片和带玻罩的盖板，灯体的顶部安装若干只散热片，灯体的底面安装带玻罩的盖板形成一发光腔，发光腔内装有带LED灯的线路板，其技术特点是所述灯体两侧分别设有进风腔和出风腔，进风腔内安装电源，进风腔和出风腔的顶部和底部均设有多个通风孔；所述灯体另外两侧设有分别位于发光腔两侧的散热通道，两散热通道均与进风腔和出风腔连通。
[0007] 所述发光腔内设有一根或一根以上与进风腔和出风腔连通的气流导热管。[0008] 所述若干只散热片上设有多个直线贯穿若干只散热片的通孔。
[0009] 采用以上技术方案后，本实用新型的有益效果是：灯体两侧设有位于发光腔两侧
3的散热通道，两散热通道均与进风腔和出风腔连通，进风腔、出风腔与两侧散热通道形成一循环通道，冷空气由灯体底部进入进风腔，流经散热通道吸热，最后由出风腔排出热空气，可对灯体发光腔两侧边散热；灯体顶部安装有若干只散热片，散热片上设有多个直线贯穿散热片的通孔，外部空气在通孔中流通，提高散热片散热效果，加快散热片对灯体发光腔顶部散热；发光腔内两侧分别设有与进风腔和出风腔连通的气流导热管，进风腔、出风腔与两侧气流导热管形成另一循环通道，冷空气由灯体底部进入进风腔，流经气流导热管吸热，最后由出风腔排出热空气，可对灯体发光腔内腔散热；在电源设于进风腔内，在灯体发光腔散热的同时，循环空气可对电源散热；发光腔内的热量由灯体发光腔两外侧的散热通道、灯体发光腔内部两侧的气流导热管经进风腔与出风腔之间空气流动散热，配合灯体发光腔顶部的散热片散热，LED路灯整体全方位散热，散热速度快、效果好，发光腔内工作环境好，LED光衰低，使用寿命长，且发光腔完全密闭，防虫、防尘效果好，LED的照明效果好，适合室外道路照明使用。
[0010] 本实用新型LED灯体发光腔内部和外侧分别设有气流导热管和散热通道，气流导热管和散热通道均连通灯体进、出风腔，且灯体顶部带有通孔的散热片，整体结构紧凑，发光腔全方位立体散热，散热速度快、效果好，发光腔内工作环境好，LED光衰低，使用寿命长，
使用成本低，且发光腔完全密闭，防虫、防尘效果好，照明效果好，无须经常维护，适合道路照明设施使用。

[0012] 图2为图1的A-A剖视图；[0013] 图3为图1的仰视图。
[0014] 图中：灯体1，盖板2，玻罩3，LED灯4，线路板5，气流导热管6，散热片7，散热通道8，通孔9，进风腔IO，出风腔ll，通风孔12，电源13。
具体实施方式
[0015] 下面结合附图对本实用新型作进一步说明。
[0016] 图1-3所示，全方位高效散热LED路灯主要包括灯体1、盖板2、玻罩3、 LED灯4、线路板5、散热片7和电源13。灯体1内设有线路板5，线路板5上设有多LED灯4，灯体1的顶部安装有多组散热片7，散热片7上设有多个垂直贯穿若干只散热片的通孔9，灯体1的底部安装带玻罩3的盖板2形成发光腔，带LED灯4的线路板5密封于发光腔内；灯体1的左、右两端分别设有进风腔IO和出风腔ll，进风腔IO和出风腔11的上、下表面均设有多只通风孔12，进风腔10内设有电源13 ;灯体1的上、下两侧均设有一位于发光腔侧边的散热通道8，灯体1发光腔内的上、下两侧均设有一气流导热管6，两散热通道8和两气流导热管6均连通进风腔和出风腔。
[0017] LED路灯照明时，灯体1发光腔内的热量由灯体发光腔两外侧的散热通道8、灯体发光腔内部两侧的气流导热管6经进风腔10与出风腔11之间空气流动散热，配合灯体发光腔顶部的散热片7散热，发光腔全方位立体散热，散热速度快、效果好，LED路灯使用寿命长。
