Problems solved by technology

[0003] However, these LED displays need to be installed outdoors, which are often directly exposed to sunlight, wind and rain, so the LED display needs to be able to prevent the entry of rainwater, dust and other sundries, so as to avoid the short circuit of the internal circuit of the LED display and other failures.
[0004] The LED display generally includes two parts: the box body and the LED display module. The LED display module is usually waterproof and dustproof on the front, and although the back is not waterproof and dustproof, the waterproof box with a sealed structure makes the LED display as a whole waterproof and dustproof. , its structure is more complex, increasing the cost
[0005] In order to solve the above problems, the LED display module is usually simply sealed, that is, the front and back of the LED display module are sealed. However, when the power of the LED display module is large, the heat dissipation effect is poor due to its limited internal space. In severe cases, it will lead to a decrease in the performance of the LED display module

Abstract

The invention discloses an LED (Light-Emitting Diode) display module which comprises a shell, a heat conductor, LED light-emitting elements and a driving circuit, wherein the LED light-emitting elements are respectively relatively arranged on two surfaces of a PCB (Printed Circuit Board); the driving circuit drives the LED light-emitting elements; the PCB is arranged in the shell; and one end of the heat conductor is subjected to heat coupling with the heating part of the driving circuit, and the other end of the heat conductor passes through the shell to reach the outer surface of the shell or is subjected to heat coupling with the inner surface of the shell. Through the mode, the heat radiating performance for the driving circuit in the LED display module can be improved greatly, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to the field of LED displays, in particular to an LED display module. Background technique [0002] The application range of large-scale LED displays is getting wider and wider, and it can be used in various places such as outdoor advertising, sports, transportation, performances, exhibitions, leasing, and gatherings. [0003] However, these LED displays need to be installed outdoors, which are often directly exposed to sunlight, wind and rain, so the LED display must be able to prevent the entry of rainwater, dust and other sundries, so as to avoid short-circuiting and other failures in the internal circuit of the LED display. [0004] The LED display generally includes two parts: the box body and the LED display module. The LED display module is usually waterproof and dustproof on the front, and although the back is not waterproof and dustproof, the waterproof box with a sealed structure makes the LED display as a whole waterpro...
