It can be appreciated that the partition 111 can reduce the influence of the heat generated by the light emission of the LED lamp panel 210 on the circuit board 220, so as to ensure the normal operation of the two. In addition, the provision of the partition plate 111 reduces the light output amount on the side away from the light output direction, and improves the light efficiency. Specifically, the LED lamp panel 210 and the circuit board 220 are respectively fixed on the partition board 111 through screws, so that the LED lamp panel 210 is ensured not to shake when in use, and the light emission is stable.
