Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a compact lighting fixture with high-efficiency heat dissipation. Background Technology

[0002] LED lights need to have good heat dissipation capabilities. When the LED chips emit light, some of the energy is converted into heat, which will cause the chip temperature to rise. Temperature has a great impact on the working performance of the LED chips. However, the traditional heat dissipation structure takes up a lot of space in the light fixture. With the increasing demand for miniaturization and lightweighting of light fixtures, how to achieve efficient heat dissipation in a limited space has become a problem that the industry urgently needs to solve. Utility Model Content

[0003] The purpose of this invention is to provide a compact lamp with high-efficiency heat dissipation, optimize the arrangement of internal components to make the components more compact, effectively reduce the overall size of the lamp, and ensure the lamp's luminous efficiency while also having high-efficiency heat dissipation performance.

[0004] To achieve the above objectives, this utility model provides a compact lamp with high-efficiency heat dissipation, including a lamp housing, a lamp bead plate, a reflector, a heat sink, and a cooling fan. The lamp housing is formed by a rear shell and a front shell. The heat sink includes a heat dissipation base, a heat-conducting copper pipe, and a heat dissipation fin assembly. The heat sink is V-shaped. One end of the heat-conducting copper pipe passes through the heat dissipation base, and the other end passes through the heat dissipation fin assembly. The cooling fan and the heat dissipation fin assembly are disposed within the rear shell. The rear shell has an air inlet and an air outlet. The bottom plate of the front shell is inclined upwards. The heat dissipation base is disposed on the bottom plate of the front shell. The lamp bead plate is disposed on the heat dissipation base.

Detailed Implementation

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figures 1 to 3 As shown, a compact lamp with high-efficiency heat dissipation according to a preferred embodiment of the present invention includes a lamp housing 1, a lamp bead plate 2, a reflector bowl 3, a heat sink 4, and a cooling fan 5. The lamp housing 1 is formed by a rear shell 11 and a front shell 12. The heat sink 4 includes a heat dissipation base 41, a heat-conducting copper pipe 42, and a heat dissipation fin assembly 43. The heat sink 4 is V-shaped. One end of the heat-conducting copper pipe 42 passes through the heat dissipation base 41, and the other end of the heat-conducting copper pipe 42 passes through the heat dissipation fin assembly 43. The cooling fan 5 and the heat dissipation fin assembly 43 are disposed within the rear shell 11. The rear shell 11 is provided with an air inlet 13 and an air outlet 14. The bottom plate of the front shell 12 is inclined upward. The heat dissipation base 41 is provided on the bottom plate of the front shell 12. The LED bead plate 2 is provided on the heat dissipation base 41. The upper end of the reflector bowl 3 is connected to the top plate of the front shell 12. The lower end of the reflector bowl 3 is connected to the heat dissipation base 41. The lower end of the reflector bowl 3 is located on the rear side of the LED bead plate 2. The front plate of the front shell 12 is provided with a light outlet 15. In this embodiment, the front plate of the front shell 12 is inclined from top to bottom toward the side away from the rear shell 11.

[0021] This utility model adopts a V-shaped heat sink 4, and the heat sink base 41 is set on the bottom plate of the front shell 12. At the same time, the lamp bead plate 2 is set on the heat sink base 41. The heat sink fan 5 can dissipate heat through the air outlet 14 in a timely manner. Through the cooperation of the lamp bead plate 2 and the reflector bowl 3, the arrangement of internal components of the lamp is optimized, making the components more compact and effectively reducing the overall size of the lamp. It also has efficient heat dissipation performance while ensuring the light effect of the lamp.

[0022] For example, the air outlet 14 is disposed on the rear plate of the rear shell 11, and the air inlet 13 is disposed on the top plate of the rear shell 11, which can promptly discharge hot gas from the air outlet 14 and effectively avoid residual gas from affecting the heat conduction and heat dissipation effect.

[0023] Furthermore, the cooling fan 5 is directly opposite the air outlet 14, and the heat dissipation fin assembly 43 is directly opposite the cooling fan 5. The heat dissipation fin assembly 43 is disposed between the air outlet 14 and the cooling fan 5, which can quickly and efficiently exchange heat with the heat dissipation fin assembly 43.

[0024] For example, the air inlet 13 is located above the heat dissipation fin assembly 43, ensuring that the fresh air entering from the air inlet 13 first passes through the heat dissipation fin assembly 43 for heat exchange before being discharged by the cooling fan 5, thereby improving heat exchange efficiency.

[0025] For example, the reflector bowl 3 is inclined from top to bottom toward one side of the rear shell 11 to achieve an anti-glare effect; furthermore, the reflector bowl 3 has a smoothly transitioned arc structure to improve the light emission effect.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
