The above technical scheme is further elaborated below:

Furthermore, an LED light source module is provided on the inner bottom of the housing, and the LED light source module is fixed to the center of the inner bottom of the housing through its aluminum substrate to fix the LED light source module to the housing.

Further, three LED light source modules are arranged on the inner bottom surface of the housing, and the three LED light source modules are fixed on the inner bottom surface of the housing through their aluminum substrates in a triangular distribution, so that the three LED light source modules are fixed on the shell.

Further, the inner surface of the housing is a smooth mirror structure.

Further, the lampshade is made of fireproof PC material.

Further, the inner surface of the lampshade is a frosted surface structure.

Furthermore, it also includes a mounting bracket, the mounting bracket includes a ring and an "I"-shaped fixing frame, the ring fits on the outside of the outer shell, and the "I"-shaped fixing frame The two sides are respectively fixed to the collar by screws.

The beneficial effects of the utility model are as follows: firstly, for the module modular downlight of this structure, the aluminum base plate of the LED light source module is fixedly arranged on the inner bottom surface of the shell, and is in full contact with the shell, which increases the heat dissipation of the LED light source module The area makes it have a good heat dissipation effect, reduces the light decay of the LED lamp beads, and improves the service life of the downlight. Second, the housing has a large space, which increases its heat dissipation area, and can meet its heat dissipation requirements without adding other heat dissipation structures, which makes the structure simple, saves materials, and reduces production costs. Third, during use, when the LED light source module is damaged, the structure of the downlight is very convenient for replacing the LED light source module, which makes maintenance simple and low in maintenance cost.
