Ventilating waterproof LED display module box

Abstract

The invention relates to a ventilating waterproof LED display module box which comprises a bottom shell and a waterproof cover plate. The waterproof cover plate covers the rear of the bottom shell, an inner cavity is enclosed by the waterproof cover plate and the bottom shell, electronic elements of an LED display module are arranged in the inner cavity, an air inlet and an air outlet are arranged on the waterproof cover plate, the air inlet comprises a plurality of air inlet slotted holes, water retaining ribs projecting outwards from the inner surface of the waterproof cover plate are arranged above the uppermost air inlet slotted hole and below the lowermost air inlet slotted hole, waterproof baffle plates cover the water retaining ribs, a waterproof ventilating cavity is enclosed by the water retaining ribs and the waterproof baffle plates, and the air outlet direction of airflow flowing out of the air outlet is parallel to the waterproof cover plate in ventilation and heat dissipation.

Description

technical field [0001] The invention relates to an LED display module, in particular to an LED display module box body which integrates a box body ventilation and heat dissipation structure and a waterproof structure. Background technique [0002] As we all know, with the development of LED technology, LED display modules made of LEDs as light sources have been widely used by people. LED display modules are a display method by controlling semiconductor light-emitting diodes. Composed of diodes, the characters are displayed by turning on and off the LED light source light during specific work. In actual implementation, it can be used as a display screen for displaying various information such as characters, graphics, images, animations, quotations, videos, and video signals. The LED display module can be used not only in the indoor environment but also in the outdoor environment, and has advantages that projectors, TV walls, and LCD screens cannot match. The reason why the ...

Problems solved by technology

[0004] For a single LED display module, its structure includes a module box. In specific applications, LED light panels, masks, and electronic components are collected in the module box, so that a single LED display The module forms an independent display unit. For such an independent display unit, relevant waterproof and heat dissipation structures must be designed during production to enable the LED display module to work normally, but as far as the current LED display modules are concerned, they are not waterproof. The design of the heat dissipation structure is too complicated, and the waterproof and heat dissipation effects are not ideal, and this is the main shortcoming of the traditional technology
