Problems solved by technology
However, since the brim of the hat not only blocks the external light, but also affects the light emitted by the LED itself, it is necessary to further consider the influence of the setting of the brim on the LED light emission.

Embodiment Construction
[0028] Such as Figure 1 to Figure 4 As shown, LED installation holes 1 are provided on the module 8 of the LED display screen cover, and a separate hat brim 2 is arranged above each LED installation hole 1, and the hat brim 2 is inclined downward. By adopting the "fragmentation technology" that independently equips each LED mounting hole 1 with a visor 2, each light-emitting point on the LED display can be evenly illuminated in the up, down, left, and right directions, reducing the halo caused by the crossing of light emitted by adjacent LEDs. And optimize light reflection more effectively.
[0029] Such as Figure 4 As shown, according to the present invention, there are two different included angles between the upper and lower slopes of the visor 2 and the horizontal direction, that is, the visor 2 has different upper surface inclination angles β and lower surface inclination angles δ. By properly setting the larger upper surface inclination angle β and the smaller lower ...

The present invention discloses an LED display screen mask, which comprises a module, on which an LED mounting hole is formed. A cap peak which inclines downwards relative to horizontal direction is arranged above the hole; an included angle between the upper surface of the cap peak and the horizontal direction is larger than an included angle between the lower surface of the cap peak and the horizontal direction; a light absorbing hole used for absorbing a part of intercrossed light between adjacent LEDs is preferably formed; and raised grains are also preferably formed on the surface. Through designing a larger upper surface inclination angle and a smaller lower surface inclination angle for the cap peak, the luminous effect of the display screen is optimized; through arranging the light absorbing hole, the raised grains are formed on the surface, so as to enable the LEDs with different wavelengths to realize diffuse reflection, so as to form various parallel and even light, thereby further effectively solving the problems of mosaic, light halo and low brightness of the display screen, and the like. In an LED novel display screen, a case body is mounted in front of the module, and mounted in a sliding manner through a track from the front part. Therefore, the invention has convenient and quick installation, reduces occupied space of the display screen, saves installation cost, and reduces maintenance difficulty.
Description
technical field [0001] The invention relates to an LED (light emitting diode) display screen mask and a new LED display screen with the mask. Background technique [0002] At present, the LED display mask mainly plays the role of fixing the LED and covering the sunlight to prevent it from affecting its light effect. In terms of the installation height of outdoor displays, LED displays are several meters high to tens of meters high, and are generally installed vertically, while LEDs are installed on the LED display mask parallel to the ground. The LED display usually adopts an oval LED, and the light-emitting angle is 85°-110° in the horizontal direction and 35°-60° in the vertical direction. According to the analysis of the LED light distribution curve, the light intensity value of the light emitted from the oval center of the elliptical LED is the largest, that is, the horizontal direction is the brightest. As the angle increases, the LED light intensity gradually weakens...
