The realization of the purpose of the utility model, functional characteristics and advantages will be further described in conjunction with the embodiments and with reference to the accompanying drawings.

Detailed ways

It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Referring to Fig. 1 to Fig. 3, an embodiment of the LED downlight of the present invention is proposed. The drive installation case 10 is installed on the bottom of the downlight lamp body, and the LED driver is installed in the drive installation case 10 . An entrance and exit 11 are provided on one side of the drive installation case 10 , and the LED driver is put into the drive installation case 10 through the entrance and exit 11 . A movably connected movable cover 12 is provided on the upper cover of the entrance and exit 11, and the movable cover 12 seals the LED driver in the driver installation shell 10 to protect the LED driver. The movable cover 12 is fixed on the drive installation case 10 through screw connection, so that the movable cover 12 is detachable, which is convenient for replacement and maintenance of the LED driver.
