[0002] The lamp housing refers to the outer shell or outer packaging of the lamp, which is used to protect the internal circuit, light source and other components, and plays a role in aesthetics, dustproof, waterproof, heat insulation, etc. The lamp housing is usually made of metal, plastic, glass and other materials, with different shapes, sizes and structures to adapt to various types of lamps.

[0003] The Chinese patent with the authorization announcement number CN210398542U discloses a lamp housing for a lamp equipped with a camera, comprising an outer lamp housing and an inner lamp housing arranged in the outer lamp housing, wherein the inner lamp housing is provided with a boss and a plurality of lamp holes, and the lamp holes are distributed on both sides of the boss; wherein the lamp holes are provided with a concave surface for changing the direction of light irradiation, and the boss is provided with a mounting hole for mounting a camera; the outer lamp housing is provided with a refractive surface for preventing glare, and the inner lamp housing is provided with a reflective surface corresponding to the refractive surface. The utility model has a simple structure and can reduce the influence of light on the camera.

[0004] However, this device still has some shortcomings: it cannot dissipate heat from the lamp housing. When the lamp is working, heat will be generated. If the heat cannot be effectively dissipated, the temperature of the components or the lamp housing may be too high, thereby affecting the life and performance of the lamp. In addition, this device is not convenient for disassembling and assembling the lamp housing. Utility Model Content

[0016] Lower lamp housing;

[0017] A fixing column is plugged and arranged on the upper lamp housing and the lower lamp housing, and is used to connect the upper lamp housing and the lower lamp housing in the working state;

[0021] Compared with the prior art, the utility model has the following beneficial technical effects:

[0022] By setting the heat dissipation blades a and the heat dissipation blades b, the upper lamp shell and the lower lamp shell are used to dissipate heat. For example, heat is generated when the lamp is working. If the heat is not effectively dissipated, the temperature of the components or the lamp shell may be too high, thereby affecting the life and performance of the lamp. Therefore, the heat dissipation blades a and the heat dissipation blades b can increase the surface area and improve the heat dissipation efficiency, thereby effectively reducing the working temperature of the lamp and extending its service life.

For example, the lamp may need to be repaired or parts may need to be replaced during use. Therefore, when the upper lamp shell and the lower lamp shell are easy to disassemble and assemble, maintenance personnel can more conveniently open the lamp to inspect and replace faulty parts, thereby reducing maintenance time and costs.

DETAILED DESCRIPTION

[0029] Embodiment 1

[0030] like Figure 1-Figure 4 As shown, a lamp housing proposed by the utility model includes a heat dissipation mechanism, a lower lamp housing 2, a fixing column 3 and a limiting column 12, wherein the fixing column 3 is plugged and arranged on the upper lamp housing 1 and the lower lamp housing 2, and is used to connect the upper lamp housing 1 and the lower lamp housing 2 in the working state, connecting blocks 4 are arranged on both sides of the upper lamp housing 1, and a damper a7 is arranged in the connecting block 4, and the fixing column 3 is connected to both ends of the damper a7, and a pushing block 5 is arranged on one side of the fixing column 3 for changing the working state of the fixing column 3, and a mounting block 8 is arranged on one side of the fixing column 3, and the pushing block 5 is connected to the other side of the mounting block 8, so that when the pushing block 5 moves, the two groups of fixing columns 3 can be squeezed inward at the same time, thereby detaching from the upper lamp housing 1 and the lower lamp housing 2. Because the lamp may need to be repaired or parts may be replaced during use, when the upper lamp housing 1 and the lower lamp housing 2 are easy to disassemble and assemble, the maintenance personnel can more conveniently open the lamp to inspect and replace faulty parts, thereby reducing maintenance time and cost.

[0031] The limiting column 12 is plugged into the upper lamp housing 1 and the lower lamp housing 2, and is used to limit the fixing column 3 in the working state. The limiting column 12 is slidably set on the pushing block 5, and the pushing block 5 is provided with a guide member for driving the limiting column 12 to slide, and the guide member includes a pulling block 9, a circular rod 10 and a damper b11; the circular rod 10 is connected to the limiting column 12 and passes through one side of the pushing block 5; one end of the damper b11 is connected to the limiting column 12, and the other end is connected to the inner wall of the pushing block 5 and is located on the outer peripheral wall of the circular rod 10; the pulling block 9 is set at one end of the circular rod 10, which is convenient for pulling out or plugging the limiting column 12 from the upper lamp housing 1 and the lower lamp housing 2, so as to limit the fixing column 3 and prevent the fixing column 3 from loosening or detaching from the upper lamp housing 1 and the lower lamp housing 2.

[0032] The working principle of this embodiment is as follows: during use, when the internal temperature of the upper lamp housing 1 and the lower lamp housing 2 is high, the motor 17 is turned on to drive the toothed disc 15 and the connecting column 18 to rotate, and the rotation of the connecting column 18 drives the heat dissipation blade b16 to rotate, and the rotation of the toothed disc 15 drives the gear 14 to rotate, thereby driving the connecting rod 19 and the heat dissipation blade a13 to rotate, thereby accelerating the heat flow in the upper lamp housing 1 and the lower lamp housing 2, thereby dissipating the heat inside. When the lamp or lamp housing needs to be replaced or maintained, first manually pull the pulling block 9 to separate the limiting column 12 from the upper lamp housing 1 and the lower lamp housing 2, and then manually squeeze the pushing block 5 inward to drive the fixing column 3 to move, thereby separating the upper lamp housing 1 and the lower lamp housing 2, and then the upper lamp housing 1 and the lower lamp housing 2 can be disassembled to maintain the parts, etc. After the replacement is completed, repeat this step to install the upper lamp housing 1 and the lower lamp housing 2.

[0033] Embodiment 2

A driving member for driving the heat dissipation blade b16 to rotate is arranged on the upper lamp housing 1; the driving member includes a motor 17 and a connecting column 18; a mounting column 6 is arranged on the upper lamp housing 1 for mounting the same; the motor 17 is arranged in the mounting column 6; the connecting column 18 vertically passes through the upper lamp housing 1 and extends into the mounting column 6 to be connected with the output shaft of the motor 17, and the heat dissipation blade b16 is arranged on the connecting column 18.

[0035] In this embodiment, the heat dissipation blades a13 and the heat dissipation blades b16 are provided to dissipate heat from the upper lamp housing 1 and the lower lamp housing 2. For example, heat is generated when the lamp is working. If the heat dissipation cannot be effectively dissipated, the temperature of the components or the lamp housing may be too high, thereby affecting the life and performance of the lamp. Therefore, the heat dissipation blades a13 and the heat dissipation blades b16 can increase the surface area and improve the heat dissipation efficiency, thereby effectively reducing the operating temperature of the lamp and extending its service life.
