The light can be limited in a specific direction or area, so that the light is prevented from being scattered or directly irradiated to the area which does not need to be illuminated, in addition, scattering and reflection of the light can be reduced, more light can be intensively irradiated to the area which needs to be illuminated, and the illumination efficiency is improved.

Description

Technical Field

[0001] The utility model relates to the technical field of bifocal lenses, in particular to a reflector for an ultra-thin bifocal lens. Background Art

[0002] The headlights of motor vehicles are also called headlamps, which are used to illuminate the road ahead of the vehicle in low visibility or at night. These headlights are mainly used to produce two types of lighting modes, namely, low beam mode and high beam mode. In low beam mode, the light beam has a very obvious light and dark cut-off line, which can provide lighting without interfering with other road participants. In high beam mode, it can illuminate a farther distance in front of the vehicle. These two modes can be switched manually or automatically according to actual conditions.

[0003] In the prior art, reflectors are usually used to achieve low beam and high beam functions, and the low beam reflectors and the high beam reflectors are arranged in a vertical direction orthogonal to the horizontal emitting direction, which causes the headlight module to have a larger size in the vertical direction (i.e., the vehicle height direction), resulting in poor applicability of the device. Therefore, we need to propose an ultra-thin reflector for dual-light lenses. Utility Model Content

[0004] The utility model aims to provide an ultra-thin reflector for a dual-light lens, aiming to solve the problem in the prior art that the headlight module has a large size in the vertical direction (ie, the vehicle height direction), resulting in poor applicability of the device.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A reflector for an ultra-thin dual-light lens comprises a low-beam reflector body and a high-beam reflector body, wherein the low-beam reflector body comprises a first bottom shell, a protrusion is arranged on one side of the first bottom shell, a mounting hole is arranged inside the protrusion, a plurality of groups of low-beam reflective bowls are arranged at the bottom of the low-beam reflector body, and the high-beam reflector body comprises a second bottom shell, a plurality of groups of connecting members are arranged on the second bottom shell, and a plurality of groups of high-beam reflective bowls are arranged on the top of the second bottom shell.

[0007] Preferably, two groups of first baffles are further included, and the two groups of first baffles are fixedly connected to one side wall of the first bottom shell, and the two groups of first baffles are located on one side of the plurality of groups of low beam reflector bowls.

[0008] Preferably, the number of the low-beam reflective bowls is set to be no less than 6, and the material of the low-beam reflective bowl is set to be high-temperature PC material.

[0009] Preferably, two groups of second baffles are further included, and the two groups of second baffles are fixedly mounted on one side wall of the second bottom shell, and the two groups of second bottom shells are located on one side of the plurality of groups of high beam reflector bowls.

[0010] Preferably, the number of the high beam reflective bowls is set to be no less than 20, and the material of the high beam reflective bowls can be set to be high-temperature PC material.

[0011] Preferably, the low beam reflector body and the high beam reflector body are overall oblate, the length and width of the low beam reflector body and the high beam reflector body are both greater than 125 mm, and the height of the low beam reflector body and the high beam reflector body are both less than 20 mm.

[0012] Preferably, a stripe-shaped structure is provided on one side wall of each of the first bottom shell and the second bottom shell, and the height of the stripe-shaped structure is set to 0.2 mm.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model arranges no less than six low-beam reflective bowls on the low-beam reflector body, and no less than twenty high-beam reflective bowls on the high-beam reflector body, and the number of the low-beam reflective bowls is the same as the number of LED light sources used for the corresponding functions. When the number of the reflective bowls is the same as the number of the LED light sources, it can ensure that the light emitted by each LED light source can be evenly reflected by the reflective bowls, thereby forming a uniform lighting effect.

[0015] 2. By setting a first baffle on the first bottom shell and a second baffle on the second bottom shell, the light shape can be divided into three parts that do not affect each other. The first baffle and the second baffle play a role in guiding the light and limit the light to a specific direction or area, thereby avoiding light scattering or directly irradiating the area that does not need lighting. In addition, it can also reduce the scattering and reflection of light, so that more light can be concentrated on the area that needs lighting, thereby improving the lighting efficiency.

[0027] The number of high beam reflector bowls 4 is set to be no less than 20, and the material of the high beam reflector bowl 4 is set to be high temperature PC material. When the temperature is too high, BMC material can be considered.
