Abstract

A lamp installed by quick plugging is disclosed, including a junction box and a lamp body, where the lamp body includes a rear cover, and two symmetrically provided installation springs are connected to the rear cover; a drive plate is provided inside the rear cover; a connecting female end is connected to the drive plate, and the connecting female end is electrically connected to the drive plate; a light source plate is also provided inside the rear cover, and a face ring is connected below the rear cover; a connecting male end corresponding to the connecting female end is installed inside the junction box; a connecting elastic sheet is connected to an upper surface of the rear cover, and connecting flanges are provided inside the junction box. An implementation method of the lamp installed by quick plugging is also disclosed. The quick connection between the drive plate and a power input is realized by matching the pluggable connecting female end and connecting male end, and the connecting female end and the connecting male end are both located in the junction box after connection so that a circuit solution of the lamp may adopt a linear non-isolated circuit, thereby reducing the circuit cost and also meeting the requirements of safety regulations.

Claims (18)

1 . A lamp, comprising a junction box and a lamp body, wherein the lamp body comprises a rear cover, and two symmetrically provided installation springs are connected to the rear cover; a drive plate is located inside the rear cover;

wherein a connecting female end is connected to the drive plate, and the connecting female end is electrically connected to the drive plate;

wherein a light source plate is also located inside the rear cover, and a face ring is connected below the rear cover;

wherein a connecting male end corresponding to the connecting female end is installed inside the junction box;

wherein a connecting elastic sheet is connected to an upper surface of the rear cover, and a connecting flange corresponding to the connecting elastic sheet is located inside the junction box;

wherein a male end bracket is connected inside the junction box and arranged with a male end installation groove, and an upper end of the connecting male end is embedded in the male end installation groove;

wherein each of two side surfaces of the connecting male end is provided with a male end fixing buckle located above the male end bracket, and each of front and rear surfaces of the connecting male end is provided with a male end limiting rib located below the male end bracket;

wherein the rear cover is arranged with a first female end installation groove, and the drive plate is arranged with a second female end installation groove corresponding to the first female end installation groove; an upper end of the connecting female end is embedded in the first female end installation groove and the second female end installation groove; and

wherein each of two side surfaces of the connecting female end is provided with a female end fixing buckle located above the rear cover, and each of front and rear surfaces of the connecting female end is provided with a female end limiting rib located below the drive plate.

2 . The lamp according to claim 1 , wherein the light source plate is connected to an inner wall of the rear cover, and a reflective paper, a light guide plate, and a diffusion plate are successively arranged from top to bottom inside the rear cover.

3 . The lamp according to claim 1 , wherein four positioning flanges are provided inside the rear cover, and the drive plate is arranged with positioning grooves corresponding to the four positioning flanges.

4 . The lamp according to claim 1 , wherein the connecting flange is provided on a side wall of the junction box, and the connecting female end is electrically connected to the drive plate through a wire.

5 . The lamp according to claim 1 , wherein the light source plate and the drive plate are an optical drive integrated plate, and a reflective cup is arranged below the optical drive integrated plate.

6 . An implementation method of the lamp according to claim 1 , comprising the steps of:

(1) embedding the connecting female end in the first female end installation groove and the second female end installation groove to realize a connection between the drive plate and the rear cover;

(2) installing the connecting male end on the male end bracket, and connecting the connecting male end to a power input line;

(3) aligning the connecting female end with the connecting male end for inserting; and

(4) matching the connecting female end with the connecting male end to realize a connection between the drive plate and a power input, and matching a connecting elastic sheet with the connecting flange to realize a connection between the lamp body and the junction box.
