When wiring is required, it is only necessary to open the cover 4 to open the open end of the base 1, and then connect the mains wire with the input line of the driving power supply 2 in the base 1. After the wiring is completed, the cover 4 is sealed on the open end of the base 1. The whole wiring process is easy to operate.

[0026] Further, such as Figure 2 and Figure 3 As shown, a mounting block 5 is provided at the corresponding positions of the two end surfaces of the cover 4 and the base 1, and a convex point 6 is provided on the outer side surface of the mounting block 5, and the convex point 6 is a hemispherical structure. The two end surfaces of the base 1 are provided with convex blocks 7 corresponding to the mounting block 5, and the convex block 7 is provided with a mounting hole adapted to the convex point 6. The cover 4 is connected to the base 1 by inserting the convex point 6 into the mounting hole. At the same time, since the outer surface of the convex point 6 is a spherical surface, it is rotatably connected to the mounting hole, so the cover 4 is rotatably connected to the base 1. When wiring is required, the cover 4 can be hung on the base 1 by rotating it, and the open end of the base 1 is opened to perform wiring operations; after the wiring is completed, the cover 4 is sealed on the open end of the base 1 by rotating the cover 4 in the opposite direction.

[0027] Further, such as Figure 4-Figure 7 As shown, the cross-section of the heat sink 8 is an R-shaped structure, including an inclined surface 801, an L surface 802, and a connecting surface 803 for connecting the inclined surface 801 and the L surface 802. A first clamping member 9 and a second clamping member 10 for mounting the heat sink 8 are provided on the bottom surface of the base 1. The heat sink 8 is fixedly mounted on the base 1 by installing the free end of the inclined surface 801 in the first clamping member 9 and the horizontal end of the L surface 802 in the second clamping member 10.

[0028] A first protrusion 11 is provided on the side of the vertical end of the L surface 802 facing the driving power supply 2, and an arc-shaped portion 12 is provided on the side of the surface cover 4 facing the L surface 802; when the surface cover 4 is sealed on the open end of the base 1, the surface cover 4 is limited to the open end of the base 1 through the snap-fit ​​cooperation between the first protrusion 11 and the arc-shaped portion 12, and at the same time, the two ends of the surface cover 4 respectively abut against the two end surfaces of the base 1.

The third clamping member 13 and the screw hole 14 are arranged opposite to each other. A groove 15 corresponding to the screw hole 14 is provided on one side of the light source board 3. The light source board 3 is fixedly installed on the inclined surface 801 by passing the screw through the groove 15 and then screwing into the screw hole 14. The other side of the light source board 3 is installed in the third clamping member 13.

[0030] A light-transmitting cover 16 is provided above the light source board 3, and the light-transmitting cover 16 covers the light source board 3. A slot 17 is provided on one side of the light-transmitting cover 16, and a snap-in groove 18 is provided on the other side of the light-transmitting cover 16. A second protrusion 19 is provided on the side of the connecting surface 803 facing the light-transmitting cover 16.

[0032] By providing a heat sink 8 and adopting an R-shaped structural design of the heat sink 8, firstly, the heat generated by the light source board 3 is dissipated through the heat sink 8; secondly, the light source board 3 and the driving power supply 2 are isolated so that the light source board 3 and the driving power supply 2 are respectively located on both sides of the base 1, so as to facilitate the wiring operation between the input line of the driving power supply 2 and the AC power line; thirdly, the snap-on method is adopted to improve the assembly efficiency of the surface cover 4, the light-transmitting cover 16, the heat sink 8 and the light source board 3.

[0033] Further, such as Figure 8 and Fig. 9 As shown, a fourth clamping component 21 and a fifth clamping component 22 for installing the driving power supply 2 are provided on the bottom surface of the base 1. The fourth clamping component 21 and the fifth clamping component 22 are arranged opposite to each other, and the driving power supply 2 is fixedly installed on the base 1 by installing the two ends of the driving power supply 2 in the fourth clamping component 21 and the fifth clamping component 22 respectively.

[0034] Preferably, the light-transmitting cover 16 is made of plastic material, such as PC or PMMMA, and the heat sink 8, the cover 4 and the base 1 are made of metal material, such as die-cast or injection-molded aluminum. The above materials have a certain elastic deformation effect to facilitate the assembly of the entire lamp.

Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
