Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a high-density LED matrix light source. Background Art

[0002] A high-density LED matrix light source is a lighting system that integrates a large number of LED (light-emitting diode) units. Its design goal is to achieve high brightness and high luminous efficacy within a relatively small area. This light source typically adopts an array layout, closely arranging LEDs to form a matrix to achieve high density. Compared with traditional single-point light sources, high-density LED matrix light sources can provide more uniform light distribution and are suitable for applications requiring high brightness and light uniformity.

[0003] A search revealed a Chinese utility model patent publication numbered CN215731775U, which discloses a matrix LED light source comprising a substrate; an LED chip matrix disposed on and electrically connected to the substrate; the LED chip matrix comprising a plurality of LED chips; a phosphor layer disposed on the upper surface of each LED chip; a white wall glue portion disposed on the substrate and surrounding the LED chips, the white wall glue portion having grooves distributed between adjacent LED chips; and a black wall glue portion disposed within the grooves and on the upper surface of the white wall glue portion, the upper surface of the black wall glue portion being flush with the upper surface of the phosphor layer. The matrix LED light source of this application has grooves disposed in the white wall glue portion between adjacent LED chips, and a black wall glue portion disposed within the grooves. When one LED light source in the matrix LED light source emits light, the side light is absorbed by the black wall glue portion and does not irradiate the phosphor layer on the adjacent LED chip, thereby preventing the adjacent LED light source from also emitting light and preventing interference between adjacent LED light sources.

[0004] However, the device often lacks the function of heat dissipation. When in use, the LED will generate heat when working. The high-density LED matrix will make the heat more concentrated. Without good heat dissipation measures, the heat will accumulate inside the light source, resulting in reduced luminous efficiency and brightness of the LED, and may even cause light decay, shortening the service life of the LED. Not only that, the device also lacks the function of adjusting the angle. When in use, in application scenarios that require specific lighting effects or lighting ranges, because the LED light source cannot adjust the beam angle, the light will be too concentrated or dispersed, resulting in uneven lighting in the target area, affecting the lighting effect and user experience.
