Abstract

The invention discloses an outdoor LED display module related to engineering components, comprising an LED light board, a light penetration cover and a back shell; wherein the LED light board is additionally provided with a plurality of LED; the facade of the LED light board is attached to the internal face of the light penetration cover; the back shell pushes against the backside of the LED light board; a gap is formed between the sides of the light penetration shell and the sides of the back shell, and waterproof glue is infiltrated into the gap. The outdoor LED display module related to engineering components is characterized in that: a light shield is attached to the outside of the light penetration cover, the positions on the light shield corresponding to the LED are provided with corresponding light transmission holes which are quadrate, rectangular, round or elliptic; a lucifuge margin is additionally arranged at the upper side of each line of the light transmission holes and a vertical slot is arranged between the adjacent light transmission holes in each line of the light transmission holes; the positions inside the light penetration cover corresponding to the LED are additionally provided with corresponding convex bodies which are matched and clamped with the light transmission holes of the light shield; the convex bodies corresponding to light transmission holes on the light shield are in a prismatic shape or a cylindrical shape. The outdoor LED display module related to engineering components has the advantages of high working reliability and strong practicality.

Description

technical field [0001] The invention relates to engineering components, in particular to an outdoor LED display module. Background technique [0002] Existing outdoor LED display modules, such as figure 1 As shown, it generally includes an LED lamp board 1', a light-transmitting cover 2' and a rear shell 3', and several LEDs 11' are attached on the LED lamp board 1'. [0003] like figure 1 As shown, the front side of the LED lamp board 1' (the side with the LED 11' attached) is attached to the inner surface of the light-transmitting cover 2', and the back shell 3' is against the back side of the LED lamp board 1'. [0004] like figure 1 As shown, a small gap S' is formed between the side 21' of the light-transmitting cover 2' and the side 31' of the rear case 3'. Since the side 21' and the side 31' are closed polygons (probably is a quadrangle), and the formed gap S' is also a closed polygon (quadrangle). Then, waterproof glue is infiltrated into the gap S', so that the...
