[0002] The existing indoor surface-mounted full-color LED display has the following defects: 1. The LED lights are directly exposed, and the visual effect is not good, especially when the screen is turned off; 2. Because there are certain intervals between the LED lights on the screen, the screen will When the brightness of each LED light is high and the brightness of each interval is low, that is, the brightness of the screen is uneven. More importantly, because of the number of pixels of the screen, if a camera or video recorder is aimed at the screen to take pictures or record videos, there will be confusion.

Embodiment Construction
[0011] The present invention will be further described in detail below in conjunction with the embodiments and with reference to the accompanying drawings.
[0012] Such as figure 1 As shown, the surface mount full-color LED display screen includes a screen body and LED surface mount lamp modules distributed on the surface of the screen body, and the LED surface mount lamp module includes LED surface mount lamps 2 and LED surface mount The bracket 1 of the stick lamp 2, the bracket 1 is similar to a container with an open top, and a reflector 3 is arranged inside, and the open top of the bracket 1 is covered with a semi-transparent diffuse reflection cover 4, and the reflector 3 and The semi-transparent and diffuse reflection cover 4 sandwiches the LED surface-mounted lamp 2 in the middle, the reflector 3 is in the shape of a groove with a certain slope, and the semi-transparent and diffuse reflection cover 4 is at a certain distance from the LED surface-mounted lamp 2 di...

The invention provides an LED surface-mounted lamp display screen, which comprises a screen body and an LED surface-mounted lamp module, wherein the LED surface-mounted lamp module comprises LED surface-mounted lamps and a sleeve member for installation of the LED surface-mounted lamps; a reflection cover is arranged in the sleeve member; a semitransparent reflection cover plate is arranged at the upper end of the sleeve member in a covering way; the LED surface-mounted lamps are clamped between the reflection cover and the transparent reflection cover plate; the reflection cover is in a shape of a groove with a certain slope; and a certain distance is reserved between the semitransparent cover plate and an LED wafer. Due to the existence of the semitransparent reflection cover plate, surface texture can be remarkably improved, in particular when a plane is closed. In addition, due to arrangement of the reflection cover behind the LED surface-mounted lamps and the semitransparent reflection cover plate in front of the LED surface-mounted lamps, a light source of each independent LED surface-mounted lamp can be amplified, so that lights of all the LED surface-mounted lamps are connected to a whole, therefore moire fringes can be prevented from occurring, and visual effect during shooting and/or video recording is improved.
Description
technical field [0001] The invention relates to an LED surface-mounted lamp module and an LED display screen, in particular to an indoor surface-mounted full-color LED display screen and an LED surface-mounted lamp module used therein. Background technique [0002] The existing indoor surface-mounted full-color LED display has the following defects: 1. The LED lights are directly exposed, and the visual effect is not good, especially when the screen is turned off; 2. Because there are certain intervals between the LED lights on the screen, the screen will When the brightness of each LED light is high and the brightness of each interval is low, that is, the brightness of the screen is uneven. More importantly, because of the number of pixels of the screen, if a camera or video recorder is aimed at the screen to take pictures or record videos, there will be confusion. Alfred stripes appear, seriously affecting the effect. [0003] At present, with the wide application of full...
