Abstract
The utility model provides a radiating type paster type light-emitting diode (LED) display screen, which aims at resolving the problem that the existing product is slow in radiating and short in service life. The radiating type paster type LED display screen comprises a radiating base casing, radiating pieces, an LED display screen module, a shading face cover and fixing bolts. The radiating base casing adopts duralumin materials and is integrally formed by casting in avoiding mode according to the position of an electronic device on the back portion of the combined driving LED display screen module board and a connector. A heat conduction piece adopts the double-face self-bonding type and is formed in hollow mode according to the position of elements on the back face of the LED display screen module. The LED display module adopts the mode that an LED lamp and a driving circuit are manufacture through the same printed circuit board (PCB), the shading face cover is formed through black poly carbonate materials in injection molding mode, and the radiating base casing, the heat conduction piece, the LED display screen module and the shading face cover are fixed through bolts. The temperature of the radiating type paster type LED display screen is 10 DEG C lower than that of a display screen adopting traditional radiating mode under the same condition, and the radiating type paster type LED display screen improves product stability and prolongs product service life.
Description
Technical field
The utility model belongs to the LED product applications, is specifically related to a kind of heat radiating type adopting surface mounted LED display screen.
Background technology
The LED display product is used; Temperature is a principal element of its life-span/quality of decision; The too high meeting of temperature is stable influential to LED's, goes down to let the decay of LED display acceleration for a long time, seriously possibly cause surface-mounted integrated circuit work undesired; Even by being burnt, thereby make the display system can't operate as normal.Statistical data shows that when temperature surpassed certain value, the component failure rate is index law to be increased.2 ℃ of the every risings of assembly temperature, reliability decrease 10%.When a plurality of LED dense arrangement were formed display system, the dissipation problem of heat was more serious.Solving thermal management issues has become the condition precedent of high-brightness LED display applications.The display screen PCB support plate natural heat dissipation generally selected for use of display screen radiating mode in the market; Outside through fan then transfer of heat to casing; This radiating mode can not effectively leave the temperature of drive IC and LED; Cause the brightness that causes drive IC back LED decay to occur because temperature is too high, shield brightness disproportionation and the flower screen, finally influence result of use and life-span thereby put in order.
Summary of the invention
The utility model has proposed a kind of heat radiating type adopting surface mounted LED display screen to the deficiency of prior art.
The utility model comprises heat radiation drain pan, conducting strip, LED display module, face shield for welders.Wherein conducting strip is positioned in the middle of heat radiation drain pan reverse side and the LED display module, and face shield for welders is placed on the LED lamp side of LED display module, and heat radiation drain pan, conducting strip, LED display module, face shield for welders arrive together through screw retention.Described heat radiation drain pan adopts the die casting of duralumin material one-body molded, and the front of heat radiation drain pan has the groove that drives unification LED display module board back electronic devices and components and connector position according to lamp, and the reverse side of heat radiation drain pan has radiating groove.Described conducting strip is selected the double-sided self-adhesive type for use, carries out the hollow out moulding according to the back element position of LED display module.Described LED display module is the pcb board that lamp drives unification, and face shield for welders is selected the injection mo(u)lding of black PC material for use.
The beneficial effect of this programme is: the utility model improves the life-span of product stability, prolongation product than low 10 degrees centigrade of the temperature under the display screen equal conditions that adopts traditional heat-dissipating.

Embodiment
Below in conjunction with accompanying drawing the heat radiation solution is described further:
The utility model comprises heat radiation drain pan, conducting strip, LED display module, face shield for welders.Wherein conducting strip is positioned in the middle of heat radiation drain pan reverse side and the LED display module, and face shield for welders is placed on the LED lamp side of LED display module.Like Fig. 1, shown in Figure 2, the heat radiation drain pan adopts the duralumin material, and driving unification LED display module board back electronic devices and components and connector position according to lamp, to dodge die casting one-body molded.As shown in Figure 3, conducting strip is selected the double-sided self-adhesive type for use, carries out the hollow out moulding according to the back element position of LED display module.Institute is shown in Figure 4, and the LED display module is the pcb board that lamp drives unification, and is as shown in Figure 5; Face shield for welders is selected the injection mo(u)lding of black PC material for use, and is as shown in Figure 6, and heat radiation drain pan, conducting strip, LED display module, face shield for welders arrive together through screw retention; Drive IC, PCB and conducting strip, heat radiation drain pan are combined closely; Heat can effectively be transmitted on the heat radiation drain pan through conducting strip, on the heat radiation drain pan convex-concave radiating groove is arranged, and effectively increases area of dissipation.Pass through the radiator fan that box house is installed then, discharge casing to the heat of box house, thereby reduce the temperature of casing, keep the even of display screen surface LED temperature.
