Embodiment 1

[0033] Example 1, such as figure 1 and 2 Shown by:

[0034] A low-beam lighting optical device for vehicle lights, comprising a reflector 2 and a spectroscopic reflector 3 matched with a light source 1, the light-emitting area of ​​the light source 1 and the spectroscopic reflector 3 are located in or below the reflector 2; the light source 1 emits A part of the light is directly irradiated on the reflector 2, and a part is directly irradiated on the spectroscopic reflector 3; the reflector 2 not only reflects the light directly from the light source 1, but also reflects the reflected light from the spectroscopic reflector 3.

[0035] In the low-beam lighting optical device of the present application, the light emitted by the light source 1 is completely or partially reflected by the combination of the reflector 2 and the spectroscopic reflector 3, and then irradiated to the projection device 4 of the car lamp, such as a projection lens, after the projection device 4 After p...

Embodiment 2

[0049] Example 2, such as figure 1 and 2 as shown,

[0050] An automobile headlamp assembly adopting the above-mentioned low-beam lighting optical device for vehicle lights, comprising a light source 1 , a projection device 4 and a low-beam lighting optical device for vehicle lights matched with the light source 1 and the projection device 4 .

[0051] The automotive headlamp assembly of the present application, due to the adoption of the above-mentioned low-beam lighting optical device, on the one hand improves the utilization rate of light energy, and on the other hand also improves the degree of freedom in the light distribution design of the headlamp, which is beneficial to improving the front light. The lighting effect of the lamp.

Abstract

The invention relates to the technical field of vehicle headlight lighting, in particular to a vehicle headlight dipped beam lighting optical device and an automobile headlamp assembly. The device comprise a reflecting cover matched with a light source, and a light splitting reflector, wherein the light-emitting area of the light source and the light splitting reflector are positioned in or belowthe reflecting cover; one part of light emitted by the light source directly irradiates the reflecting cover, and the other part directly irradiates the light splitting reflector; and the reflecting cover not only directly reflects light from the light source, but also reflects reflected light from the light splitting reflector. The device can improve the efficiency of light energy utilization, further improve the design freedom degree through the introduction of the light splitting reflector, and flexibly control the projection distribution of light, thereby being beneficial to meeting of therequirement on dipped beam lighting.

Description

technical field [0001] The invention relates to the technical field of vehicle lamp lighting, in particular to an optical device for low beam illumination of vehicle lamps and an automobile headlamp assembly. Background technique [0002] In the technical field of vehicle lighting, in order to achieve different lighting in different driving environments, current lighting fixtures usually include high beam lighting and low beam lighting. It improves the wider visual area for the driver. However, it is precisely because of its wide irradiation range and long irradiation distance that it may have an extremely adverse effect on the normal driving of other vehicles. Therefore, in the lighting device of the vehicle Introduced low beam structure with small irradiation range and irradiation distance. In this way, the switching between high and low beams can be used together to ensure that the vehicle can drive normally in an environment with poor lighting conditions. [0003] As fa...
