Description

Technical Field

[0001] The utility model relates to the field of vehicle auxiliary lamps, in particular to a vehicle auxiliary lamp with high-efficiency heat dissipation. Background Art

[0002] The LED lamps used in vehicle auxiliary lights have high power, which results in more heat being generated when emitting light. If this heat is not released in time, the LED lamps will burn out. In addition, the riding process is often very long, and the heat dissipation efficiency of the vehicle auxiliary lights needs to be high to avoid long-term high temperatures, which will increase the probability of LED lamps being burned out. Traditional vehicle auxiliary lights only conduct heat by setting up metal radiators to improve the heat dissipation effect, but this heat dissipation effect is poor. Therefore, it is necessary to design a vehicle auxiliary light with efficient heat dissipation to solve the problem of LED lamps heating up and burning out during long-term riding. Utility Model Content

[0003] The utility model aims to provide a vehicle auxiliary lamp with high-efficiency heat dissipation.

[0004] To achieve this purpose, the utility model adopts the following technical solutions:

[0005] Provided is a vehicle auxiliary lamp with efficient heat dissipation, comprising a lamp holder and a lamp body mounted on the lamp holder, and also comprising a radiator, wherein the lamp body is provided with a heat-conducting column for heat conduction with a lamp panel, the radiator is fixedly mounted on the heat-conducting column, a protective ring sleeved on the outer edge of the radiator is fixedly provided on the lamp body, and an arc-shaped air inlet hole is opened on the protective ring.

[0006] Furthermore, the outer edge of the lamp body is olive-shaped, and an olive-shaped shell is adopted.

[0007] Furthermore, the arc of the arc-shaped air inlet hole is greater than degrees and less than degrees, and one end of the arc-shaped air inlet hole is located in the middle of the lamp body, and the other end of the arc-shaped air inlet hole is located at the lower part of the lamp body.

[0008] Furthermore, the radiator is provided with a plurality of radiating fins evenly distributed along the central axis, and the diameter of the radiating fins located outside the lamp body is smaller than the diameter of the radiating fins located inside the lamp body.

[0009] The beneficial effects of the utility model are as follows: the vehicle auxiliary light with efficient heat dissipation is connected to the heat-conducting column through a radiator, and the radiator is cooled by cold wind during riding. When dissipating heat, a rotating blowing method is adopted, so that the area where the cold wind can contact the radiator is increased, thereby further improving the heat dissipation effect and solving the problem of heating and burning of LED lights during long-term riding.

[0016] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0017] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0018] Reference Figures 1 to 4 The vehicle auxiliary lamp with high efficiency heat dissipation shown in the figure comprises a lamp holder 1 and a lamp body 2 mounted on the lamp holder 1, and also comprises a radiator 3. The lamp body 2 is provided with a heat-conducting column 2a for heat conduction with the lamp board, and the radiator 3 is fixedly mounted on the heat-conducting column 2a. The lamp body 2 is fixedly provided with a protective ring 2c sleeved on the outer edge of the radiator 3, and an arc-shaped air inlet 2b is opened on the protective ring 2c. When the vehicle is riding, the lamp body 2 will move against the wind, and the cold wind contacting the outer surface of the lamp body 2 will enter the inside of the protective ring 2c along the arc-shaped air inlet 2b. The cold wind will rotate along the inner edge of the protective ring 2c, and the rotating cold wind will take the heat on the radiator 3 out of the outside of the lamp body 2. Among them, the radiator 3 is installed on the heat-conducting column 2a by an extrusion process.

[0019] The outer edge of the lamp body 2 is olive-shaped, and with an olive-shaped shell, the cold wind can move more closely to the outer wall of the lamp body 2, that is, strong cold wind can enter the interior of the protective ring 2c, thereby achieving a better cooling effect.

[0020] The arc of the arc-shaped air inlet 2b is greater than 90 degrees and less than 180 degrees, and one end of the arc-shaped air inlet 2b is located in the middle of the lamp body 2, and the other end of the arc-shaped air inlet 2b is located at the lower part of the lamp body 2. The heat-conducting column 2a has such a structural setting, so that the cold air can be better kept in the protective ring 2c for rotation, and the cold air is prevented from being discharged at a high speed, and such a structural position setting can prevent rainwater from entering from the top.

[0021] The radiator 3 is provided with a plurality of heat sinks evenly distributed along the central axis. The diameter of the heat sink located on the outside of the lamp body 2 is smaller than the diameter located on the inside of the lamp body 2. This structural setting enables the cold air to have less resistance when being discharged outward and reduces the noise generated by the heat sink cutting the cold air.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
