Description

大功率LED灯具High Power LED Lamps

技术领域 technical field

本实用新型涉及LED照明领域,特别提及一种大功率LED灯具。The utility model relates to the field of LED lighting, in particular to a high-power LED lamp.

背景技术 Background technique

LED作为一种新兴的绿色光源,具有节能、环保等诸多优势,被越来越多的应用到各种照明领域。LED是一种固态光源,通过将电能直接转化为可见光输出。随着LED技术的不断发展,目前的LED光源的功率已经很高,可以发出高亮度的光,这种大功率的LED已被应用到各种大型场地的照明设备中。大功率LED虽然可以发出高亮度光,但受限于技术,其将电能转化为光能的效率仍没有达到100%,目前一些技术较先进的厂商生产的大功率LED的转化效率也就能达到80%左右,仍有20%左右的电能被转化成热能,这些热能如果不能及时有效地从LED中传导并散发出去,会极大的影响LED的使用寿命。因此,现有的大功率LED灯具中都会配备有各种各样的散热设备,对LED中的热量进行传导并散发。目前,大功率LED灯具中采用的散热设备一般都是由很多个散热片组成的被动式散热结构,LED被安装到铝基板上做成LED灯板,LED灯板再安装到散热器表面,散热过程是热量由LED灯板上传导至散热器的基板上,再传导至各个散热片上,最后散热片通过热辐射的方式将热量散发。这种散热结构对于功率不是特别高的LED灯具来说,散热效果可以满足要求,但对于需要超高亮度的大功率LED灯具来说,其散热效率已严重不足,由于散热效率过低,大量的热量积聚在散热器上,使LED上的热量很难再传导至散热器上散发,严重地影响到了灯具的使用寿命。As an emerging green light source, LED has many advantages such as energy saving and environmental protection, and is increasingly applied to various lighting fields. LED is a solid-state light source that converts electrical energy directly into visible light output. With the continuous development of LED technology, the power of the current LED light source is already very high, which can emit high-brightness light. This high-power LED has been applied to the lighting equipment of various large venues. Although high-power LEDs can emit high-brightness light, limited by technology, the efficiency of converting electrical energy into light energy has not yet reached 100%. At present, the conversion efficiency of high-power LEDs produced by some manufacturers with more advanced technologies can also reach 100%. About 80%, about 20% of the electric energy is still converted into heat energy. If the heat energy cannot be conducted and dissipated from the LED in a timely and effective manner, the service life of the LED will be greatly affected. Therefore, the existing high-power LED lamps will be equipped with various heat dissipation devices to conduct and dissipate the heat in the LED. At present, the heat dissipation equipment used in high-power LED lamps is generally a passive heat dissipation structure composed of many heat sinks. The heat is conducted from the LED lamp board to the base plate of the heat sink, and then to each heat sink, and finally the heat sink dissipates the heat through thermal radiation. This heat dissipation structure can meet the requirements for the heat dissipation effect of LED lamps with low power, but for high-power LED lamps that require ultra-high brightness, the heat dissipation efficiency is seriously insufficient. Due to the low heat dissipation efficiency, a large number of The heat accumulated on the radiator makes it difficult for the heat on the LED to be transmitted to the radiator, which seriously affects the service life of the lamp.

实用新型内容 Utility model content

针对上述现有技术存在的不足,本实用新型的目的是提供一种大功率LED灯具,它具有非常优异的散热效果,可以满足超高亮度的大功率LED灯具的散热要求。In view of the deficiencies in the above-mentioned prior art, the purpose of this utility model is to provide a high-power LED lamp, which has a very excellent heat dissipation effect and can meet the heat dissipation requirements of the ultra-high-brightness high-power LED lamp.

为了实现上述目的,本实用新型所采用的技术方案是:大功率LED灯具,包括反光罩及安装于反光罩的中心孔处的LED光源,其特征在于,所述LED光源包括管状散热器及贴装于散热器外表面的多个LED灯板,所述散热器具有套置在一起的外管和内管,所述外管与内管之间通过多个散热片连接成一体结构。In order to achieve the above purpose, the technical solution adopted by the utility model is: a high-power LED lamp, including a reflector and an LED light source installed at the center hole of the reflector, characterized in that the LED light source includes a tubular radiator and a sticker A plurality of LED lamp boards installed on the outer surface of the radiator. The radiator has an outer tube and an inner tube nested together. The outer tube and the inner tube are connected to form an integral structure through a plurality of cooling fins.

优选地,所述外管为正棱柱形状,并且每个侧面都贴装有一个LED灯板。Preferably, the outer tube is in the shape of a regular prism, and an LED light board is mounted on each side.

优选地,所述内管为圆筒状或正棱柱形状。Preferably, the inner tube is in the shape of a cylinder or a regular prism.

优选地,所述散热片之间还设有散热棱,所述散热棱由所述外管的内侧壁延伸而出并且端部悬空设置。Preferably, a heat dissipation rib is further provided between the heat dissipation fins, and the heat dissipation rib is extended from the inner side wall of the outer tube and its end is suspended.

优选地,所述散热片之间还设有散热棱,所述散热棱由所述内管的外侧壁延伸而出并且端部悬空设置。Preferably, heat dissipation ribs are further provided between the heat dissipation fins, and the heat dissipation ribs extend from the outer side wall of the inner tube and the ends of the heat dissipation ribs are suspended.

本实用新型与现有技术相比具有如下优点:通过在管状散热器外表面贴装多个LED灯板,可以提供超高亮度的照明要求,当然发热量也很大,因此散热器被设计成具有套置在一起的外管和内管,外并且管与内管之间通过多个散热片连接成一体结构。散热器被设计成这种结构后,不仅使散热器的散热面积增加多倍,同时在散热器内形成多条通道,比如内管内部的通过,以及散热片、外管及内管之间形成的通道,这些通道中由于热量分布不均,使得通道内的空气也会冷热不一,空气会主动地形成快速的对流。这样一来,散热器不仅可以通过热辐射的方式散发热量,还可以更好地通过空气循环进行散热,使散热效果成几倍地增加,散热器上的热便能快速散发,也不会形成热量积聚,可以更好更有效率地将LED上的热量散发掉。因此本实用新型的大功率LED灯具,具有非常优异的散热效果,可以满足超高亮度的大功率LED灯具的散热要求。Compared with the prior art, the utility model has the following advantages: by mounting a plurality of LED lamp panels on the outer surface of the tubular radiator, it can provide ultra-high brightness lighting requirements, and of course the heat is also very large, so the radiator is designed as It has an outer tube and an inner tube that are nested together, and the outer tube and the inner tube are connected to form an integral structure through a plurality of cooling fins. After the radiator is designed with this structure, it not only doubles the heat dissipation area of the radiator, but also forms multiple channels in the radiator, such as the passage inside the inner tube, and the formation between the fins, the outer tube and the inner tube. Due to the uneven distribution of heat in these channels, the air in the channels will also be hot and cold, and the air will actively form rapid convection. In this way, the radiator can not only dissipate heat through thermal radiation, but also better dissipate heat through air circulation, so that the heat dissipation effect is increased several times, and the heat on the radiator can be dissipated quickly without forming Heat accumulation can dissipate the heat on the LED better and more efficiently. Therefore, the high-power LED lamp of the present invention has a very excellent heat dissipation effect, and can meet the heat dissipation requirements of the ultra-high-brightness high-power LED lamp.
