The lamp housing 1 can be fixed to the ceiling using a suspension wire L.

Refer to fig. 3 and 4. The lamp envelope comprises a bottom wall 11 and two opposite side walls 12 on both sides of the bottom wall 11. A groove 120 opened in a horizontal direction is formed on both side walls 12 near the light exit edge by a rolling process. The opening of the groove 120 may face the inner side or the outer side of the lamp housing 1 in the horizontal direction, preferably toward the outer side of the lamp housing 1. Specifically, the groove 120 is formed by enclosing a first bending portion 121 directly connected to the sidewall 12 and bent 90 degrees in the inner direction of the lamp housing 1, a second bending portion 122 connected to the first bending portion 121 and bent 90 degrees in the direction opposite to the bottom wall 11, and a third bending portion 123 connected to the second bending portion 122 and bent 90 degrees in the outer direction of the lamp housing 1. The tail end of the third bending part 123 is located on the inner side of the extension line of the outer side surface of the side wall 12. A fixing structure which is integrally formed by injection molding and made of the same material as the light diffusion plate 3 is arranged on one side of the two sides of the light diffusion plate 3 facing the bottom wall 11 of the lamp shell, and the fixing structure comprises a first baffle 31 and a second baffle 32 which are respectively positioned on the two sides of the groove 120 in the horizontal direction; the top end of the first baffle 31 is provided with a first bending plate 311 matched with the groove 120, the top end of the second baffle 32 is provided with a second bending plate 321 matched with the first bending part 121, and the first baffle 31, the first bending plate 311 and the light-diffusing plate 3 are encircled to form a clamping groove 331 matched with the third bending part 123.

Refer to fig. 3 and 4.
