Abstract

The invention relates to a patch LED outdoor waterproof module. A transparent cover is arranged between a pedestal and a faceplate; a faceplate positioning column and a pedestal positioning column are arranged on the transparent cover; a corresponding locating hole and a corresponding threaded column are respectively arranged on the faceplate and the pedestal to fixedly connect the transparent cover with the pedestal and the faceplate; the frame around is fastened and filled with a sealant (12); a PCB circuit board is fixedly connected with the pedestal; LED lamps are regularly arranged on the PCB circuit board; LED lamp holes corresponding to the LED lamps are disposed on the faceplate, and loopholes are uniformly distributed on the faceplate. The patch LED outdoor waterproof module can efficiently realize the waterproof effect of the patch LED display screen, so that the patch LED display screen can be used in all-weather condition, the display effect is good, and the images are clear.

Description

The paster LED outdoor water-proof module

Technical field

The present invention relates to a kind of LED outdoor water-proof module, especially a kind of paster LED outdoor water-proof module that is suitable for outdoor application belongs to the LED Display Technique.

Background technology

LED display is formed LED demonstration module plate by the light emitting diode module that several dot matrix are arranged, shows various patterns, information, video.The LED light emitting diode has direct insertion or SMD, direct insertion LED lamp point module, waterproof problem when outdoor application solves easily, can be from the outside directly with glue with integral sealing, but the display screen visual angle that direct insertion LED lamp is made is little, visual angle, the left and right sides is ± 50 °, and last downwards angle of visibility is ± 25 °, in outdoor application certain limitation is arranged.The display screen visual angle that adopting surface mounted LED lamp point module is made is big, but because of the unavailable glue integral sealing of SMD lamp point module, otherwise can influence the display performance of luminous tube, therefore, adopt paster LED to do the display screen module and can only be used in indoorly, its outdoor water-proof technology is a problem anxious to be solved.

Summary of the invention

For solving the existing waterproof problem of paster LED display screen in outdoor application, the invention provides a kind of paster LED outdoor water-proof module, the paster LED modular structure is designed to enclosed construction, can under all weather conditions, use, satisfy the waterproof demand.

The present invention realizes its purpose by the following technical solutions:

The paster LED outdoor water-proof module comprises panel, base, LED lamp, PCB circuit board, between panel and base, translucent cover is installed, this translucent cover is provided with panel reference column and base reference column, on panel, be provided with and panel reference column corresponding positioning hole, base is provided with and the corresponding threaded post of base reference column, translucent cover is fixedlyed connected with panel with base, and frame is fastening and fill with fluid sealant all around.

Described PCB circuit board is fixed on the base; Described LED lamp is regularly arranged on the PCB circuit board;

Described panel is provided with and LED lamp corresponding LED lamp hole, and uniform loophole.

Because the present invention installs translucent cover between base and panel, seal with fluid sealant panel and base contact position, the transparent whole module of a sealing of formation, and it is non-watertight and can only be in the situation of indoor use to have changed the paster LED display screen.

Beneficial effect of the present invention is:

1. novel structure can effectively be realized the waterproof problem of paster LED display screen the paster LED display screen being used under all weather conditions.

2. the paster LED display screen visual angle that the assembly unit of a plurality of paster LED outdoor water-proof module is made is big, visual angle, the left and right sides ± 60 °, and last downwards angle of visibility ± 60 ° solved the little problem in display screen visual angle that direct insertion LED lamp is made, and display effect are good, clear picture.
