Double-heat-conductive-piece clamping-plate-type LED display unit module

Abstract

The invention relates to the technical field of LED display screens, in particular to a double-heat-conductive-piece clamping-plate-type LED display unit module. The module comprises a sealing glue body, a heat conductive panel, a heat conductive back panel, a heat conductive column and an LED displaying lamp panel which is composed of circuit boards, an IC chip and an LED illumination tube; the circuit boards overlap one another and are clamped between the heat conductive panel and the heat conductive back panel, a lamp body passing hole is formed in the part, corresponding to the LED illumination tube, of the heat conductive panel, the heat conductive column penetrates through the heat conductive back panel and the circuit board and is fixedly locked on the heat conductive panel, and thesealing glue body covers the heat conductive panel and at least integrally wraps the heat conductive panel and the LED displaying lamp panel. According to the module, the heat conductive panel and the heat conductive back panel are utilized to form a double-layer heat conductive piece which clamps the LED displaying lamp panel, rapid heat conductivity and outward heat dissipating can be conductedon the heat generated by the direct shining of the sun and the heat generated by the LED displaying lamp panel with the cooperation of the heat conductive column, the structural sealing performance of the whole module can be enhanced by using the sealing glue body, secondary locking can be conducted on the heat conductive panel, the LED displaying lamp panel and the heat conductive back panel toensure the stability of the structure of the module.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a double-heat-conducting sheet splint type LED display unit module. Background technique [0002] As we all know, the general process structure of traditional LED display unit modules is: after installing the LED display lamp board in the plastic case, pour liquid sealant into the plastic case to seal the LED display lamp board in the plastic case, and wait for the liquid to seal After the glue is cured, the mask is placed on the light-emitting side of the LED display panel and locked together with the plastic shell, thus forming a finished LED display unit module. [0003] However, when the traditional LED display unit module is placed in an outdoor environment (especially in an environment exposed to sunlight), since the sealing gel and the plastic gel constituting the mask are poor thermal conductors, the heat generated by the sun exposure will be It accumulates i...

[0003] However, when the traditional LED display unit module is placed in an outdoor environment (especially in an environment exposed to sunlight), since the sealing gel and the plastic gel constituting the mask are poor thermal conductors, the heat generated by the sun exposure will be It accumulates in the sealant on the front surface of the LED display lamp board; at the same time, the circuit board located on the back side of the LED light-emitting tube is made of fiber material, which is also a poor heat conductor. ) will also accumulate in the sealant body at the same time; based on this, the heat generated by sunlight exposure will be superimposed with the heat generated by the LED lamp, and because the entire module lacks a structural channel for heat transfer and dissipation, the continuous The internal temperature of the sealant will rise sharply under the sun exposure and the continuous operation of the unit module, and the temperature will change sharply and continue to rise with the ambient temperature and the brightness of the display light board. The high temperature will cause the unit module and even outdoor LED display screens generally have many problems such as excessive lamp temperature and uncontrollable temperature rise, which will lead to increased dead light rate, serious light decay, deformation of display modules, frequent failures, etc. This is the LED outdoor display industry that has existed for many years. ills
