CN 202049690 U

The utility model discloses an LED display screen display module with an aluminium housing. The LED display screen display module comprises a plurality of LED luminescent tubes arranged in an array manner and is characterized in that the LED luminescent tubes are welded on a PCB (printed circuit board); pins of the LED luminescent tubes penetrate the PCB and are exposed outside to form welding legs; an aluminium mask with buckles is arranged on the LED luminescent tubes, as well as the luminous front side and peripheral side surface of the PCB; a radiating back panel with buckles and capable of being buckled with the aluminium mask is arranged at the back of the PCB; the radiating back panel comprises radiating baseplates, the buckles and connection edgings connected with box bodies; the LED luminescent tubes and the PCB are tightened up through screws so as to allow all the welding legs of the LED luminescent tubes and the radiating baseplates to be in even joint and close contact; water-proof packing glue is encapsulated on the PCB and the radiating back panel, which are fixed through the screws, so as to form a whole in a solidifying manner; and the aluminium housing directly transmits and radiates out heat generated by LEDs, so as to reduce and steady the working temperature of the LEDs and promote the reliability and screen quality of the LED display module.

本实用新型公开了一种铝质外壳LED显示屏显示模组，包括数个呈阵列排列的LED发光管，其特征在于，所述LED发光管焊接在PCB板上，并且所述LED发光管引脚穿过PCB板外露引脚并形成焊脚，所述的LED发光管、PCB板发光正面和周边侧面设置有带卡扣的铝面罩，所述的PCB板背面设置有带卡扣并且能够和铝面罩扣合的散热背板，所述的散热背板包括散热底板、卡扣以及和箱体连接的连接边条，通过螺丝将LED发光管、PCB板拉紧使LED发光管所有焊脚与散热底板平整接合且紧密接触，防水密封胶灌封于已用螺丝固定的PCB板及散热背板使之固化为一个整体，本实用新型采用铝质外壳将LED产生的热量直接传导并散发出去，降低并稳定LED工作温度，提升了LED显示模组的可靠性及屏幕品质。

currently on the market existing outdoor LED display, the display module is the use of plastic injection molding shell, LED indicator light panel installation refilling sealed waterproof glue, with addition of shading mask combination. As the LED outdoor display using ultraviolet irradiation faced, high and low temperature as well as harmful gases such as sun and rain or harsh environments, the plastic in the environment after use after years of widespread deformation aging, seriously affecting the body of the screen display quality; and because the plastic shell can not be achieved directly on the LED heat, exposure to the sun in hot weather, LED luminous efficiency and lifetime are reduced, limiting further improve manufacturing quality LED screens.

目前市面上已有的LED户外显示屏，其显示模组是采用塑胶注塑成形外壳后，加装LED显示灯板再注封防水胶，配加遮光面罩组合而成。由于LED户外显示屏使用中面临紫外线辐照，高低温度变化以及日晒雨淋或者有害气体等各种恶劣的环境，塑胶在经历多年上述环境使用后普遍出现变形老化，严重影响屏体显示质量；同时由于胶壳无法实现对 LED直接散热，在太阳曝晒的高温天气中，LED光效及寿命均会缩减，限制了 LED屏幕制造品质进一步提升。

In order to solve the existing technology products shortcomings and deficiencies, the utility model provides an aluminum housing LED display module, the utility model with aluminum shell heat generated by the LED directly transmitted and distributed out reduce and stabilize the LED working temperature, improve the reliability of the LED screen and the screen quality, and because aluminum shell and face mask by cold deformation and aging capabilities are superior to the plastic shell, thus ensuring lasting LED display module stable and reliable quality.

为解决现有技术生产的产品的缺点和不足，本实用新型提供一种铝质外壳LED显示屏显示模组，本实用新型采用铝质外壳将LED产生的热量直接传导并散发出去，降低并稳定LED工作温度，提升了 LED屏幕运行的可靠性及屏幕品质，同时由于铝质外壳及面罩受冷热变形及抗老化各项能力均优于塑胶壳，从而保证LED显示模组长久的品质稳定可靠。

[0004] This utility model technical solution adopted is one kind of aluminum housing LED display display modules, including a number in an array arrangement of the LED light tube, characterized in that the LED light tube is soldered on PCB, and the LED light tube pin through the PCB board and the formation of the exposed pin fillet, said LED light tube, PCB board luminous front and side is provided with a belt buckle around the aluminum mask, set the back of the PCB board There belt buckle and snap-fit ​​visor can and aluminum heat backplane, backplane, including the cooling of the cooling plate, and the case snaps as well as a connecting edge strips, LED light tube via screws, PCB board to make taut LED light tube all welded flat feet and the heat bonding and close contact with the floor, reaching base LED light pipe and heat conductivity as well as directly fixed PCB board, waterproof potting sealant has been fixed with screws on the backplane PCB board and heat to cure as a whole, to waterproof and strengthen the role of the overall module strength, potting waterproof  sealant can overflow in the heat back two outer end face waterproof sealant installation of a sealed plastic blocking plate.

 本实用新型采用的技术方案是，一种铝质外壳LED显示屏示模组，包括数个呈阵列排列的LED发光管，其特征在于，所述LED发光管焊接在PCB板上，并且所述LED发光管引脚穿过PCB板外露引脚并形成焊脚，所述的LED发光管、PCB板发光正面和周边侧面设置有带卡扣的铝面罩，所述的PCB板背面设置有带卡扣并且能够和铝面罩扣合的散热背板， 所述的散热背板包括散热底板、卡扣以及和箱体连接的连接边条，通过螺丝将LED发光管、 PCB板拉紧使LED发光管所有焊脚与散热底板平整接合且紧密接触，达到LED发光管与散热底板直接导热以及与PCB板固定，防水密封胶灌封于已用螺丝固定的PCB板及散热背板使之固化为一个整体，达到防水及强化整体模组强度作用，灌封防水密封胶时在散热背板两个能溢出防水密封胶的外端面加装有封胶堵板。
