Description

Technical Field

[0001] The utility model relates to the technical field of lighting lamps, in particular to a vehicle lamp with a double refraction light source. Background Art

[0002] Current automobile headlights generally include lenses / lenses, reflective mechanisms, dimmer switching mechanisms, etc. The dimmer switching mechanism is located between the reflective mechanism or the light source and the lens to achieve the switching between high and low beams. However, traditional automobile lamps mostly use matrix single-light LED combined lens modules, and after improvement, dual-light lenses are also used, with the light configuration of one low beam plus multiple high beam auxiliary. However, such traditional headlights generally use a dual-lamp cup plus multiple direct-beam methods for optical processing. However, because the high-beam cup of the dual-lamp cup must use the upper hemisphere of the lens, the direct-beam optical processing will significantly affect the light efficiency of the high-beam cup, thereby affecting the light brightness and increasing power consumption. At the same time, the structure of the headlight using dual-lamp cups is also more complex, with higher costs, larger size and weight. Summary of the invention

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a vehicle lamp with a birefringent light source, which solves the problem that the low beam and the high beam of the vehicle lamp cannot be integrated in a small space.

[0026] Current automobile headlights generally include lenses / lenses, reflective mechanisms, dimmer switching mechanisms, etc. The dimmer switching mechanism is located between the reflective mechanism or the light source and the lens to achieve the switching between high and low beams. However, traditional automobile lamps mostly use matrix single-light LED combined lens modules, and after improvement, dual-light lenses are also used, with the light configuration of one low beam plus multiple high beam auxiliary. However, such traditional headlights generally use a dual-lamp cup plus multiple direct-beam methods for optical processing. However, because the high-beam cup of the dual-lamp cup must use the upper hemisphere of the lens, the direct-beam optical processing will significantly affect the light efficiency of the high-beam cup, thereby affecting the light brightness and increasing power consumption. At the same time, the structure of the headlight using dual-lamp cups is also more complex, with higher costs, larger size and weight.

[0027] In order to solve the above problems, this embodiment discloses a vehicle lamp with a birefringent light source, the structure of which is as follows: Figure 1 and Figure 2As shown, the vehicle lamp is a vehicle lamp with a double refraction light source, comprising a shell 100 with an opening on one side, a lamp body installed in the shell 100, and a mirror body installed at the opening of the shell 100, the mirror body comprising a low light spherical surface 301 and a high light spherical surface 302, the high light spherical surface 302 comprising a first spherical surface 303 and a second spherical surface 304 arranged at intervals; the lamp body comprises a first lamp body 201, a second lamp body 202, a third lamp body 203 installed in the shell 100, and a lamp cup 204 located above the first lamp body 201, the first lamp body 201 faces the inner side of the lamp cup 204 and is used to refract light to the low light spherical surface 301 through the lamp cup 204, the second lamp body 202 faces the first spherical surface 303, and the third lamp body 203 faces the second spherical surface 304.

[0028] In this embodiment, the second spherical surface 304 is formed by splicing at least four curved surfaces. Figure 4 It can be seen that the light path of the second lamp body 202 is refracted by the first spherical surface 303 and then emitted as multiple parallel straight lines, thereby forming a circular light spot; and the structure of the second spherical surface 304 makes the light path of the third lamp body 203 directly emit the second spherical surface 304, thereby forming a rectangular light spot. The light spot illuminated by the headlight of this embodiment can be referred to Figure 5 .

[0029] Specifically, in the vehicle lamp with a birefringent light source of the present embodiment, the first lamp body 201 illuminates the first spherical surface 303 through the lamp cup 204 to realize low beam illumination, and the second lamp body 202 and the third lamp body 203 directly illuminate the first spherical surface 303 and the second spherical surface 304 to realize high beam illumination. This structure can solve the problem of the difficulty in integrating low beam and high beam in a narrow space; at the same time, the circular light spot emitted by the first spherical surface 303 and the rectangular light spot emitted by the second spherical surface 304 can avoid the contradiction between the illumination range of the high beam and the central light intensity, thereby improving the overall lighting effect of the vehicle lamp of the present embodiment.

[0030] Furthermore, a fixing cover 101 for fixing the mirror body is detachably provided at the opening of the housing 100, and the fixing cover 101 is provided with a through hole 102 for exposing the mirror body, and the fixing cover 101 can realize the detachability of the mirror body. In addition, a positioning column 103 is provided on one side of the opening of the housing 100, and a groove 305 corresponding to the positioning column 103 is provided on one side of the mirror body. Through the cooperation of the groove 305 and the positioning column 103, the mirror body can be rotated and limited during assembly to prevent the mirror body from being out of position, and the installation of the mirror body can also be positioned.

[0031] Furthermore, a cooling fan 104 is installed in the shell 100, and a plurality of ventilation holes 105 are provided at the lower end of the shell 100. Since the lamp body generates more heat when working, and the smaller shell 100 is not conducive to the internal air circulation, the cooling fan 104 can be provided to effectively dissipate the heat of the shell 100, so that the inside of the shell 100 always maintains a suitable working temperature.

[0032] Example 2

[0033] In this embodiment, a positioning groove is provided on one side of the opening of the housing 100, and a convex column corresponding to the positioning groove is provided on one side of the mirror body. In other words, the mirror body and the housing 100 of this embodiment are also limited and installed by the positioning groove and the convex column. It should be noted that, except for the features recorded in this embodiment, the other features are the same as those of Embodiment 1, and will not be repeated here.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
