Waterproof LED display screen

Abstract

The invention relates to the field of LED, in particular to a waterproof LED display screen. The waterproof LED display screen comprises a base, a supporting column, a fixed frame body, heat dissipation fans and a waterproof cover. Two sets of movable wheels are fixedly mounted on the bottom of the base, and two sets of the supporting columns are fixedly connected with the two sides of the top ofthe base and are fixedly mounted on the two sides of the top of the base through fixing sleeves; the fixed frame body is fixedly connected with the tops of the supporting columns, glass is arranged atthe base surface center of the fixed frame body, a sealing cushion is arranged between the glass and the fixed frame body, and guide grooves are formed in the surface of the glass; an LED display screen body is arranged on the inner side of the back face of the glass, loud speakers are arranged at the left and right end of the fixed frame body, radiator shells are arranged on the back face of thefixed frame body, heat dissipation grids are arranged on the surfaces of the radiator shells, and the heat dissipation fans are fixedly mounted on the portion, close to the inner sides of the heat dissipation grids, in the fixed frame body. The whole waterproof LED display screen is simple in structure and good in rain prevention effect and has certain popularization value.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to a waterproof LED display screen. Background technique [0002] LED display is a kind of flat-panel display, which is composed of small LED module panels, and is used to display various information such as text, image, video, and video signals. It has been widely used and has become an electronic advertising medium, and the scope of application continues to expand. The typical representative is the street advertising LED display. [0003] However, the street advertising LED display has its own inevitable shortcomings: first, it is vulnerable to the impact of rain. Once the rain enters the circuit inside the LED display, it will cause unpredictable damage to the entire circuit system; while the existing The moisture-proof and rain-proof performance of the LED display screen is relatively poor, and the waterproof performance during heat dissipation is also relatively poor, so a waterproof LED d...

[0003] However, the street advertising LED display has its own inevitable shortcomings: first, it is vulnerable to the impact of rain. Once the rain enters the circuit inside the LED display, it will cause unpredictable damage to the entire circuit system; while the existing The moisture-proof and rain-proof performance of the LED display is poor, and the waterproof performance during heat dissipation is also relatively poor, so a waterproof LED display is needed to improve the above problems
