The surface of the frame formed after the end cover 10 is assembled with the module mounting frame 20 is smoother and more beautiful.

[0041] As shown in some specific embodiments, Figure 2 and Figure 5 the two ends of the LED module 40 are provided with third screw holes 41, the horizontal wall 25 is provided with fourth screw holes 251, and the LED module 40 is fixedly connected with the horizontal wall 25 of the two module mounting frames 20 by screws through the third screw holes 41 and the fourth screw holes 251. The LED module 40 is installed on the horizontal wall 25 of the module mounting frame 20, avoiding being directly installed on the horizontal plate 24 to expose the screws on the surface of the lamp body.

[0042] As shown in some specific embodiments, Figure 5As shown, in some specific embodiments, the transverse wall 25 of the module mounting bracket 20 includes a first wall 252 and a second wall 253 connected together. The first wall 252 is connected to the side plate 23, and the second wall 253 is connected to the side wall 26. A third step 254 is provided between the first wall 252 and the second wall 253. The third step 254 is located inside the snap-fit ​​groove 21, and the third step 254 is opposite to the side plate 23. Figure 4 As shown, the snap-fit ​​portion 11 is provided with a fourth step portion 113 that mates with the third step portion 254. Figure 2 and Figure 5 As shown, the LED module 40 has fifth screw holes 42 at both ends, and a sixth screw hole 255 on the second wall 253. The LED module 40 and the module mounting bracket 20 are fixedly connected by screws using the fifth screw holes 42 and the sixth screw holes 255. The transverse wall 25 is designed with a thinner first wall 252 and a thicker second wall 253. The second wall 253 is designed to accommodate the thickness of the screws, allowing the two ends of the LED module 40 to be fixedly mounted on the second wall 253 by screws. At the same time, the thickness of the first wall 252 is reduced, thus reducing the overall weight of the module mounting bracket 20 and making it easier to achieve a lightweight lamp. Depending on actual needs, each LED module 40 can have one or more pairs of fifth screw holes 42 at both ends, and the same number of sixth screw holes 255 can be opened on the second wall 253 accordingly. Figure 2 As shown, in this embodiment, each LED module 40 has two pairs of fifth screw holes 42.
