Problems solved by technology

However, because LED lights generate a lot of heat when they work, the heat dissipation problem has always been the bottleneck in practical applications for front and rear lights that use LED lights as light sources.
Because if there is a lack of heat dissipation structure in the car light or the heat dissipation effect of the heat dissipation structure is not good, the heat generated by the LED light cannot be released or cannot be effectively released, which may cause the LED light to overheat and reduce the output brightness of the car light, and may even cause LED burnt out lamp

Embodiment 1

[0027] Such as figure 1 As shown, in the present embodiment, the automobile lamp is mainly used as a headlight of an automobile, and it includes a housing 10, a decorative frame 20, a mask 30, a light source, a light distribution bowl 70, an aluminum-based circuit board 90, and cooling unit. The interior of the casing is a hollow cavity, and the decorative frame 20 , the mask 30 , the light source, the light distribution bowl 70 , the power supply unit, and the heat dissipation unit are all arranged in the casing 10 .

[0028] The shape and size of the casing 10 can be set according to different vehicle models in practice. In this embodiment, the shape of the casing 10 is a cuboid.

[0029] The mask 30 is disposed on the front surface of the casing 10, and correspondingly, the side opposite to the front surface of the casing is called the rear surface. In this embodiment, the mask 30 is bowl-shaped, and the curvature of the bowl-shaped mask is determined according to actual ...

Embodiment 2

[0045] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 lies in that the arrangement position of the heat sink with the pillar-shaped connecting seat is different.

[0046] In the heat sink, a pedestal-shaped connection seat 81 protrudes from the lower surface of the housing, and the heat dissipation part of the heat sink is arranged at the lower part of the housing.

[0047] Other structures in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0049] The main difference between this embodiment and Embodiment 1 is: in this embodiment, the number of light sources is different, the number of radiators is different, and the number of light distribution bowls is different.

[0050] Wherein, one LED lamp group is used as the light source, one radiator is used correspondingly, and one light distribution bowl is correspondingly used.

[0051] In addition, in this embodiment, the shape of the heat dissipation fins in the radiator is different from the shape of the heat dissipation fins in Embodiment 1.

[0052] Such as Figure 5 As shown, in this embodiment, the cross-sectional shape of the cooling fins is trapezoidal.

[0053] Other structures in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention provides an automobile lamp which comprises a housing (10), a light source arranged in the housing and a heat dissipating unit used for discharging heat produced by the light source out of the housing. The automobile lamp has good heat dissipating performance.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to an automobile lamp and an automobile using the automobile lamp. Background technique [0002] At present, LED lights are widely used as light sources in the front and rear lights of vehicles, especially the headlights of automobiles. In order to achieve a wider irradiation angle and a longer irradiation distance, high-power LED lights need to be used as lighting sources. However, since LED lamps generate a lot of heat when they are working, heat dissipation has always been a bottleneck in practical applications for front and rear lights using LED lamps as light sources. Because if there is a lack of heat dissipation structure in the car light or the heat dissipation effect of the heat dissipation structure is not good, the heat generated by the LED light cannot be released or cannot be effectively released, which may cause the LED light to overheat an...
