Description

SMD LED outdoor waterproof module

technical field

The invention relates to an outdoor LED waterproof module, in particular to a patch LED outdoor waterproof module suitable for outdoor use, which belongs to the LED display technology.

Background technique

The LED display screen is composed of several light-emitting diode modules arranged in a dot matrix to form an LED display module board to display various patterns, information, and videos. LED light-emitting diodes have in-line or patch type, in-line light-emitting diode light point module, the waterproof problem when used outdoors is easy to solve, you can directly seal the whole with glue from the outside, but the in-line LED lamp is made The viewing angle of the display screen is small, the left and right viewing angles are ±50°, and the up and down viewing angles are ±25°, which has certain limitations for outdoor use. The display screen made of SMD LED light point module has a large viewing angle, but the SMD light point module cannot be sealed with glue as a whole, otherwise it will affect the display performance of the light-emitting tube. Therefore, SMD LED is used as the display screen module. The battery pack can only be used indoors, and its outdoor waterproof technology is an urgent problem to be solved.

Contents of the invention

In order to solve the waterproof problem of the existing SMD LED display screen in outdoor use, the present invention provides a SMD LED outdoor waterproof module. The structure of the SMD LED module is designed as a closed structure, which can be used under all-weather conditions , to meet the waterproof requirements.

The present invention adopts following technical scheme to realize its purpose:

The SMD LED outdoor waterproof module includes a panel, a base, an LED lamp, and a PCB circuit board. A transparent cover is installed between the panel and the base. The transparent cover is provided with a panel positioning column and a base positioning column. The positioning hole corresponding to the positioning column of the panel, the threaded column corresponding to the positioning column of the base is provided on the base, the transparent cover is fixedly connected with the base and the panel, the surrounding frame is fastened and filled with sealant.

The PCB circuit board is fixed on the base; the LED lights are regularly arranged on the PCB circuit board;

LED lamp holes corresponding to the LED lamps are arranged on the panel, and light-transmitting holes are evenly distributed.

Since the present invention installs a transparent cover between the base and the panel, the contact between the panel and the base is sealed with a sealant to form a sealed transparent integral module, which changes the situation that the patch LED display screen is not waterproof and can only be used indoors .

The beneficial effects of the present invention are:

1. The structure is novel, which can effectively realize the waterproof problem of the SMD LED display, so that the SMD LED display can be used under all-weather conditions.

2. The SMD LED display screen made by assembling multiple SMD LED outdoor waterproof modules has a large viewing angle, the left and right viewing angles are ±60°, and the up and down viewing angles are ±60°, which solves the problem that the display screen made of in-line LED lights has a small viewing angle. The problem, and the display effect is good, the image is clear.
