As shown in fig. 1 to 3, the optical structure for a vehicle lamp according to the first aspect of the present invention includes a first primary optical element 1, a beam splitter 3, and a first secondary optical element 41, which are sequentially disposed from back to front, and a second primary optical element 2 is disposed above or below the beam splitter 3; the first primary optical element 1 is arranged such that part of its outgoing light rays can be transmitted through the beam splitter 3 to the first secondary optical element 41 and projected through the first secondary optical element 41, and the second primary optical element 2 is arranged such that part of its outgoing light rays can be reflected through the beam splitter 3 to the first secondary optical element 41 and projected through the first secondary optical element 41.

The working process of the car lamp module is as follows: the first primary optical element 1 and the second primary optical element 2 respectively receive and transmit light emitted by the light source 7 corresponding to the first primary optical element and the second primary optical element, outgoing light of the first primary optical element and the second primary optical element is incident to the beam splitting member 3 from different sides of the beam splitting member 3, and split by the beam splitter 3, so that part of the outgoing light of the first primary optical element 1 can be transmitted to the first secondary optical element 41 through the beam splitter 3 for projection, part of the outgoing light of the second primary optical element 2 can be reflected by the beam splitter 3 to the first secondary optical element 41 for projection, i.e. the light received by the first primary optical element 1 and the second primary optical element 2, can be transmitted to the first secondary optical element 41 for projection, and can form a corresponding number of pixels, and, accordingly, under the condition that the opening size of the first secondary optical element 41 is not changed, the number of pixels of the vehicle lamp module can be effectively increased. When being applied to ADB high beam module, if keep pixel quantity unchangeable, then can shorten the left and right sides size of high beam module, greatly reduced car light structure's of adjusting luminance design degree of difficulty.

In the present invention, part of the outgoing light of the first primary optical element 1 and the second primary optical element 2 is transmitted or reflected by the beam splitter 3, while the light reflected by the beam splitter 3 in the outgoing light of the first primary optical element 1 and the light transmitted by the beam splitter 3 in the outgoing light of the second primary optical element 2 are not effectively utilized, in order to improve the utilization efficiency of the light emitted by the light source 7 in the present application, in some preferred embodiments of the present invention, as shown in fig. 1 to 3, a reflector 5 is disposed on the side of the beam splitter 3 away from the second primary optical element 2, a second secondary optical element 42 is disposed in front of the reflector 5, and part of the outgoing light of the first primary optical element 1 can be reflected to the reflector 5 by the beam splitter 3 and reflected to the second secondary optical element 42 by the reflector 5 for projection, part of the outgoing light of the second primary optical element 2 can be transmitted to the reflecting member 5 through the beam splitting member 3, and reflected to the second secondary optical element 42 through the reflecting member 5 to be projected. At this time, when the emergent light of the first primary optical element 1 is transmitted to the beam splitter 3, part of the light is directly transmitted to the first secondary optical element 41 through the beam splitter 3 for projection, and meanwhile, part of the light is reflected to the reflector 5 through the beam splitter 3 and then reflected to the second secondary optical element 42 through the reflector 5 for projection; when the emergent light of the second primary optical element 2 is transmitted to the beam splitter 3, part of the light is reflected to the first secondary optical element 41 through the beam splitter 3 for projection, and meanwhile, part of the light is directly transmitted to the reflector 5 through the beam splitter 3 and then reflected to the second secondary optical element 42 through the reflector 5 for projection. Through the cooperation of the beam splitter 3 and the reflector 5, the emergent light rays of the first primary optical element 1 and the second primary optical element 2 are respectively formed into a part of light rays to be transmitted to the first secondary optical element 41 and a part of light rays to be transmitted to the second secondary optical element 42, so that the number of pixels formed by the light rays projected by the first secondary optical element 41 and the second secondary optical element 42 is further increased, and meanwhile, the light utilization rate of the vehicle lamp optical element is effectively improved.

The reflecting member 5 in the present invention may be a mirror or other element having a reflecting function, and preferably, the reflecting member 5 is a plane mirror or a curved mirror, and has a higher light reflection efficiency for the light incident to the reflecting member 5.

As a preferred embodiment of the dimming assembly 6 in the present invention, as shown in fig. 6, the dimming assembly 6 includes a rotating shaft 61 and at least one dimming element 62, the dimming element 62 is a light shielding plate or a light transmitting plate, and the dimming element 62 is mounted on the rotating shaft 61, so that light incident to the dimming assembly 6 can selectively pass through one of the dimming elements 62 or not pass through any one of the dimming elements 62 by rotating, and exit to the first secondary optical element 41 and/or the second secondary optical element 42 for projection, thereby implementing a corresponding lighting function or a signal lamp function.

The shape and material of the light control element 62 are designed according to the light distribution requirements (including the requirement of illumination intensity and the requirement of light chromaticity) of the lighting function or the signal lamp function required by the vehicle lamp module. The light-adjusting element 62 may be a light-transmitting plate of a Daytime Running Light (DRL), which is made of a light-scattering material, and can diffuse light incident to the light-adjusting element 62 and transmit white light, thereby realizing a daytime running light function; or the turn signal lamp light-transmitting plate is made of a light scattering material, can diffuse light and transmit yellow light, and realizes the function of the turn signal lamp; or the near light shading plate is made of an opaque material, the structure of the near light shading plate is the same as that of the traditional near light shading plate (with a cut-off structure), and part of light rays are shielded to realize the near light function.
