Technical Field

[0001] The utility model relates to the field of lamps, and specifically to a lamp housing with good heat dissipation effect. Background Technique

[0002] A lamp housing, also known as a lamp body or lampshade, is a structural component surrounding a light source (such as a light bulb or LED), used to protect internal components and sometimes to enhance the lighting effect; the design and materials of the lamp housing can affect the overall appearance, durability, and thermal management ability of the lamp; common lamp housing materials include metals, plastics, glass, and ceramics, etc., and each material has its specific aesthetic and functional characteristics.

The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0022] According to an embodiment of the present utility model, a lamp housing with good heat dissipation effect is provided.

[0023] Now, the present utility model will be further described in conjunction with the accompanying drawings and specific implementation manners. As Figures 1-4 shown, the lamp housing with good heat dissipation effect according to an embodiment of the present utility model includes a housing 1. Installation slots 2 are provided on both sides of the top end of the housing 1, and the two groups of installation slots 2 are connected by a bracket 3; an inner ring 4 is provided inside the housing 1, an installation cavity 5 is formed between the inner ring 4 and the housing 1, a first heat dissipation air cavity 6 is provided at the top end of the installation cavity 5, a second heat dissipation air cavity 7 is provided on one side of the installation cavity 5, a heat dissipation component 8 is provided inside the second heat dissipation air cavity 7, and an installation frame 9 is provided outside the heat dissipation component 8; a plurality of first heat dissipation ducts 10 that cooperate with the first heat dissipation air cavity 6 and the installation cavity 5 are evenly opened on the inner wall of the inner ring 4, a plurality of inner fins 11 are evenly provided on one side of the first heat dissipation ducts 10 and on the inner wall of the inner ring 4, the shape of the first heat dissipation air cavity 6 is circular, and a plurality of second heat dissipation ducts 12 that cooperate with the plurality of installation cavities 5 and the second heat dissipation air cavity 7 are evenly opened at the bottom end of the circular shape.

[0024] With the aid of the above technical solution, the present utility model can discharge the heat generated by the lamp under the combined action of the inner ring 4, the installation cavity 5, the first heat dissipation air cavity 6, the second heat dissipation air cavity 7 and the heat dissipation component 8, significantly improving the thermal management performance of the lamp, extending the service life of the lamp, and ensuring its stability and reliability in various environments; the installation cavity 5 between the inner ring 4 and the housing 1, as well as the first heat dissipation air cavity 6 and the second heat dissipation air cavity 7 form a clever air flow path, increasing the path length of the air flow, improving the heat exchange efficiency, enabling the air to absorb heat more fully during the flow process, and effectively discharging the heat.

[0025] In one embodiment, for the above-mentioned second heat dissipation air cavity 7, the second heat dissipation air cavity 7 is composed of a semi-circular cavity 13 arranged from the inside to the outside and hollowed cavities 14 located on both sides of the housing 1. Moreover, a heat dissipation component 8 is arranged inside the hollowed cavities 14, thus forming a clever air flow path, increasing the path length of air flow, improving the heat exchange efficiency, enabling the air to absorb heat more fully during the flow process, and effectively discharging the heat.

[0026] In one embodiment, for the above-mentioned heat dissipation component 8, the heat dissipation component 8 includes a mounting base 801 arranged inside the hollowed cavity 14. At the top of the mounting base 801, there is a mounting ring 802. The mounting ring 802 is connected to a motor 804 through a plurality of support rods 803. One end of the output shaft of the motor 804 is provided with a fan blade 805. Thus, under the action of the heat dissipation component 8, heat can be effectively absorbed from the heat source of the lamp, and the heat is transferred to the external environment through the mounting frame 9, accelerating the dissipation of heat.

[0027] The working principle of the heat dissipation component 8 is as follows:

[0028] Under the control of an external controller, the motor 804 is controlled and started. Under the action of the output shaft of the motor 804, the fan blade rotates, absorbs heat from the heat source of the lamp, and transfers the heat to the external environment through the mounting frame 9.

[0029] In one embodiment, for the above-mentioned mounting frame 9, a plurality of strip-shaped heat dissipation holes 15 are arranged on one side of the mounting frame 9. Thus, by increasing the surface area of the heat dissipation component, the heat exchange efficiency is improved, making the heat dissipation more rapid and efficient.

[0030] To facilitate the understanding of the above technical solution of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

[0031] During actual application, under the action of the heat dissipation component 8, air flow is generated. The air flows through the first heat dissipation air cavity 6 and the second heat dissipation air cavity 7, and at the same time absorbs the heat generated by the lamp from the mounting cavity 5 and the first heat dissipation hole passage 10. After the air in the heat dissipation air cavity absorbs heat, it flows out through the second heat dissipation hole passage 12 and the strip-shaped heat dissipation holes 15, effectively transferring the heat to the external environment, thereby reducing the internal temperature.

[0032] The working principle of the heat dissipation component 8 is as shown above.

[0033] In summary, by means of the above technical solutions of the present utility model, the present utility model can remove the heat generated by the lamp under the combined action of the inner ring 4, the installation cavity 5, the first heat dissipation air cavity 6, the second heat dissipation air cavity 7 and the heat dissipation assembly 8, significantly improving the heat management performance of the lamp, extending the service life of the lamp, and ensuring its stability and reliability in various environments; the installation cavity 5 between the inner ring 4 and the housing 1, the first heat dissipation air cavity 6 and the second heat dissipation air cavity 7 form a clever air flow path, increasing the path length of the air flow, improving the heat exchange efficiency, enabling the air to absorb heat more fully during the flow process, and effectively discharging the heat.
