The heat dissipation assembly comprises a heat dissipation plate 240 and a heat dissipation body 250, the lighting assembly is mounted on the heat dissipation plate 240, the heat dissipation plate 240 transfers heat generated by the lighting assembly to the heat dissipation body 250, and the heat dissipation is accelerated by the heat dissipation body 250.

Specifically, a stepped surface 121 is disposed on an inner side wall of the case 120, and an edge of the heat dissipation plate 240 is fixedly connected to the stepped surface 121, so that a space is formed between the heat dissipation body 250 and the bottom surface of the case 120, and the power supply assembly 270 is disposed at the space between the heat dissipation body 250 and the bottom surface of the case 120.

In such a mounting structure, the heat radiator 250 does not contact other components, has a sufficient heat radiation space, and the heat radiation unit, the power supply unit 270, and the illumination unit are all disposed in the case 120, thereby having a certain waterproof property. The lighting device provided by the utility model can ensure the heat dissipation effect and simultaneously has waterproof property.

Referring to fig. 3, optionally, a first connection portion 111 is disposed at an edge of the upper cover 110, and a second connection portion 123 corresponding to the first connection portion 111 is disposed on the box body 120. Illustratively, the first connection portion 111 and the second connection portion 123 are threaded connection holes, and a screw or a bolt passes through the threaded connection holes to enable the first connection portion 111 and the second connection portion 123 to be matched, so that a sealed space is formed inside the box body 120, and the waterproof performance is further improved.

The upper cover 110 is provided with a light-transmitting area corresponding to the lighting assembly, and the light-transmitting area covers the transparent cover plate for light to pass through.

The transparent cover is disposed inside the upper cover 110, the pressing piece 113 is disposed inside the upper cover 110, and the pressing piece 113 mounts the transparent cover on the inner surface of the upper cover 110.

In the conventional illumination lamps such as the projector, the transparent cover plate 112 and the illumination assembly are usually combined into a whole. In this way, on the one hand, the sealing performance is required to be high, and on the other hand, the light-emitting body 211 is covered by the transparent cover plate, which hinders heat dissipation to some extent.

In this embodiment, the transparent cover plate is mounted on the upper cover 110, so that a certain interval can be reserved between the lighting assembly and the upper cover 110 while light is ensured to pass through, and the heat dissipation area of the lighting assembly is increased.

Optionally, a waterproof member is disposed at a joint between the edge of the transparent cover plate and the upper cover 110 to prevent water from leaking through the gap.

Referring to fig. 4, optionally, a blocking groove 122 is formed on the surface of the box body 120 for engaging with the upper cover 110, and the blocking groove 122 is formed as a closed annular groove along the edge of the box body 120.
