Problems solved by technology

Since the light from the point light source is divergent in all directions, in order to improve the clarity and brightness of the display, it is common practice to increase the brightness of the LED light-emitting unit as a whole, which leads to increased power consumption
[0003] In addition, the light that is not used effectively, especially the light that diverges upwards, exacerbates light pollution
[0004] As mentioned above, using the fan 410' to dissipate heat requires installing a chassis 400' to protect the fan 410' on the bracket 300'. The disadvantage of this structure is that the setting of the chassis 400' increases the thickness of the LED display, which is not conducive to LED display. The Trend of Display Thinner and Lighter

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 2 As shown, the LED display module of the present invention includes: a transparent mask 100, a lamp panel 200, and a bracket 400. The transparent mask 100 is arranged on the front of the lamp panel 200, and the bracket 400 is arranged on the back of the lamp panel 200. The transparent Several parallel grooves 110 are arranged on the mask 100 .

[0023] Several parallel grooves 110 are set on the transparent mask 100 of the above-mentioned LED display module, and the grooves 110 can change the one-dimensional emission angle, that is, the grooves 110 in the horizontal direction change the longitudinal emission angle and the grooves in the vertical direction. 110 changes the lateral emission angle, and only changes the one-dimensional emission angle of the parallel groove 110, which has a light-gathering effect similar t...

Abstract

The invention discloses an LED (Light-Emitting Diode) display screen module comprising a lamp panel, a bracket arranged on the back face of the lamp panel and a transparent face shade arranged on the front face of the lamp panel, wherein a plurality of parallel grooves are arranged on the transparent face shade. The parallel grooves arranged on the transparent face shade of the LED display screen module can change the emergent angle of light rays emitted by LEDs and play a role of light condensation; and on the premise of the same energy consumption, the brightness is improved, thus achieving the purpose of taking both display brightness and low energy consumption into account.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to an LED display module. Background technique [0002] Such as figure 1 As shown, a traditional LED display module usually includes the following layers: a grid mask 100', a light panel 200', a bracket 300' and a chassis 400'. The LED lighting unit is set on the light panel 200'; the mesh mask 100' is set on the front of the light panel 200' to protect the light panel 200'; the bracket 300' is set on the back of the light panel 200' to fix the light panel 200'; the chassis 400' is used to fix the fan 410' and other electrical components. Since the luminescence of the point light source is divergent in all directions, in order to improve the clarity and brightness of the display, it is common practice to increase the luminance of the LED light-emitting unit as a whole, which leads to increased power consumption. [0003] In addition, the light that is not used effectively, especially the ligh...
