The terminology is based on the direction or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore It should not be construed as a limitation of the present invention.

In the description of the present invention, it should be noted that, unless otherwise expressly specified and limited, the terms "arrangement", "connection" and "installation" should be understood in a broad sense, for example, the connection may be a fixed connection or a Detachable connection, or integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or the internal communication between the two elements or the interaction relationship between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

A vehicle light optical element provided by the first aspect of the present invention, referring to FIGS. 1 to 39 , includes a light incident portion, a transmission portion and a light exit portion that are arranged in sequence from the back to the front and are integrally formed. The light incident portion includes a plurality of along the left and right Light incident structures 11 arranged in directions, each light incident structure 11 includes a light incident surface 111 and a reflective surface 112, the reflective surface 112 is set as a paraboloid or a paraboloid-like surface, and the front end surface of the light exit portion is formed as a light exit surface 22, incident on the light incident surface The light of 111 can be reflected by the reflecting surface 112 corresponding to the light incident surface 111 and then enter the transmission part, and then transmitted to the light exit part through the transmission part and projected through the light exit surface 22 .

In the optical element of the car light provided by the above basic technical solution, the light incident part includes a plurality of light incident structures 11 arranged in the left and right direction. Correspondingly, the transmission part and the light exit part are matched with the light incident structure 11, so that the optical element of the car light Forming a narrow and long shape, small size and low cost, it is especially suitable for adaptive (ADB, Adaptive Driving Beam) high beam lighting.

In order to better illustrate the working process of the optical element of the vehicle light provided by the present invention, the following is a detailed introduction and description when the optical element of the vehicle lamp is applied to the lamp module. The lamp module is provided with a light incident structure. 11 corresponds to the light source 3 set. The light emitted by the light source 3 is incident from the light incident surface 111 to the reflecting surface 112 corresponding to the light incident surface 111, and is reflected by the parabolic or parabolic-like reflecting surface 112, and then enters the transmission part, and then is transmitted to the light exit part through the transmission part and passes through the transmission part. The light emitting surface 22 projects to form a desired light shape. In the present invention, the reflective surface 112 is set as a paraboloid or a paraboloid-like surface, and according to the optical characteristics of the paraboloid reflection or paraboloid-like reflection, the light source 3 can be set as a point light source and located in the focal area of the reflective surface 112, and the light emitted by the point light source is corresponding to The reflective surface 112 of the reflective surface 112 shows parallel light or approximately parallel light irradiating forward, and the light does not diffuse in the up and down direction. On the premise of ensuring the same light effect, the upper and lower dimensions of the light emitting part can be reduced, and the upper and lower dimensions of the light emitting part can be realized in the upper and lower directions. The size is designed to be less than or equal to 20mm.

When the headlight module is applied to ADB high beam lighting, the light source 3 can be set to correspond to the light incident structure 11 one-to-one. During use, when other road users appear in front of the road, the corresponding light source can be turned off. Part of the light source 3, so that the corresponding local light shape forms a dark area to avoid dazzling other road users (especially oncoming vehicles), this process can cooperate with the ADB control system, and the optical element of the vehicle light of the present invention has high light distribution flexibility , strong applicability.

In the present invention, the light incident part, the transmission part and the light emitting part are integrally formed, so that the integration of the optical elements of the vehicle light is high, and the reflective surface 112 of the light incident part is integrated with the transmission part and the light emitting part. It is a paraboloid or a paraboloid-like surface, which can not only realize the convergence and collimation of the light incident on the light incident surface 111, which is beneficial to improve the light utilization rate, but also can improve the stability and optical accuracy of light transmission, so that the formed light shape effect is good. The optical efficiency is high, and the optical structure of the optical element of the vehicle light is simple and the overall size is small.

As a preferred embodiment of the transmission part in the present invention, the transmission part includes a first light channel 12 and a second light channel 21 arranged in sequence from the back to the front, and the light incident on the light incident surface 111 can pass through the light incident surface 111 The corresponding reflective surface 112 enters the first optical channel 12 after being reflected, and then transmits to the second optical channel 21 through the first optical channel 12 , and transmits to the light exit portion through the second optical channel 21 , and finally projects through the light exit surface 22 . At this time, the first optical channel 12 and the second optical channel 21 are integrally formed. Although they are independent parts in FIGS. 6 to 12 , 17 to 19 , 50 and 51 , they are only for showing In fact, the two are inseparable. It should be further noted that the light incident part, the first light channel 12 , the second light channel 21 and the light exit part of the optical element of the vehicle light in the present invention can be integrally formed with the same material, or can be integrally formed with different materials. The materials of the above four materials may be different, or the materials of two of them may be the same, or the materials of three of them may be the same. When the molding materials of the first optical channel 12 and the second optical channel 21 are different, a boundary structure will be formed between the two. The first optical channel 12 enters the second optical channel 21 after being refracted at the boundary structure; the first optical channel 12 When the material of the second light channel 21 is the same, there is no boundary structure between the two.

As a preferred embodiment of the optical element of the vehicle light in the present invention, the first light channel 12 and the light incident portion are formed as the first light guide body 1 , the second light channel 21 and the light exit portion are formed as the second light guide body 2 , The molding material of the first light guide body 1 is different from the molding material of the second light guide body 2 , so that a boundary structure is formed between the first light channel 12 and the second light channel 21 . The material of the first light channel 12 is the same as that of the light entrance part, and the material of the second light channel 21 is the same as that of the light exit part. The light channel 12 is transmitted to the boundary structure, is refracted at the boundary structure and then enters the second light channel 21 , then is transmitted to the light exit portion through the second light channel 21 , and finally projected through the light exit surface 22 . The boundary structure can adjust and change the optical path of the light in the transmission part, and form a light distribution surface for adjusting the light shape, which makes the light distribution design more flexible, so that the light shape formed by the projection of the light emitted by the light exit surface 22 meets the regulatory requirements. The first light guide body 1 and the second light guide body 2 in the present invention are formed by different transparent materials, and can be respectively made of PC, PMMA, silica gel, resin or glass.

Preferably, the refractive index of the molding material of the first light guide body 1 is smaller than the refractive index of the molding material of the second light guide body 2, so that when the light is transmitted from the first light channel 12 to the second light channel 21, the light refraction angle When the angle of incidence is smaller than the light incident angle, more light can be transmitted from the second light channel 21 to the light exit part for projection, which can further improve the utilization rate of the light by the second light guide 2 . Specifically, the first light guide body 1 may be formed of silica gel or PMMA material, and the second light guide body 2 may be formed of PC material.

In the present invention, the boundary structure may be a plane or a curved surface. As a preferred embodiment of the boundary structure in the present invention, referring to FIGS. 6 to 12 , 17 to 19 , 50 and 51 , the boundary structure includes a plurality of boundary surfaces 4 arranged in the left-right direction. The light incident structures 11 are arranged in a one-to-one correspondence. At this time, after the light emitted by the light source 3 corresponding to each light incident structure 11 is incident from the corresponding light incident surface 111 , after being reflected by the corresponding reflective surface 112 , it sequentially passes through the first light channel 12 corresponding to the light incident structure 11 , The interface 4 and the second optical channel 21 are finally projected through the light-emitting surface 22, and the interface 4 and the light-incident structure 11 are arranged in a one-to-one correspondence, which is more conducive to optimizing the distribution of light when the light enters the second optical channel 21 from the first optical channel 12. light effect, thereby improving optical efficiency.

Preferably, referring to FIG. 6 and FIG. 7 , the interface 4 is set as a smooth kyphosis curved surface formed by stretching the boundary setting curve 41 in the vertical direction, so as to be able to level the light incident on the interface 4 . Unidirectional collimation; the light emitting surface 22 is set as a smooth convex curved surface formed by stretching the light emitting setting curve 221 in the horizontal direction, so that the light incident on the light emitting surface 22 can be collimated vertically and unidirectionally. The interface 4 plays a role of horizontal unidirectional collimation while refracting and distributing the light entering the second optical channel 21 from the first optical channel 12 , so that the light shape effect is better. When the interface 4 and the light incident structure 11 are set in a one-to-one correspondence, the boundary setting curves 41 of different interface 4 may be the same or different. The light distribution requirements are designed, which has the advantage of flexible light distribution; the light output setting curve 221 is a curve that protrudes forward, and the formed light output surface 22 is continuous and smooth, not segmented, so that the emitted light can be collimated up and down. effect.

It should be noted that the "horizontal unidirectional collimation" can be understood as follows: As shown in Figure 4 , the cross-section of the interface 4 in the horizontal direction is a kyphosis curve, which has a convergence effect and can refract the light. It is relatively large and can have a certain collimation effect on the divergent light. As shown in Figure 5, in the vertical section, the cross section of the interface 4 in the vertical direction is a straight line or almost a straight line, so that the interface 4 is in the vertical direction. The deflection ability of the divergent light in the straight direction is far inferior to that in the horizontal direction. Light is deflected in the horizontal direction. The "vertical single-direction collimation" can be understood as follows: as shown in FIG. 5 , in the vertical section, the cross-section of the light-emitting surface 22 in the vertical direction is a convex curve, which has a convergence effect and has a negative effect on the polarization of light. The degree of refraction is large, which can have a certain collimation effect on the divergent light. As shown in FIG. 4, the sectional line of the light-emitting surface 22 in the horizontal direction is a straight line or almost a straight line, so that the light-emitting surface 22 in the horizontal direction has a horizontal direction to the divergent light. The deflection ability is far inferior to the deflection ability of the divergent light in the vertical direction, and it does not have a collimating effect. It deflects light in the vertical direction.

Since the interface 4 mainly deflects the light in the horizontal direction, the light exit surface 22 mainly deflects the light in the vertical direction, so that the imaging magnification of the interface 4 to the light source 3 in the horizontal direction is greater than that of the light exit The imaging magnification of the surface 22 to the light source 3 in the vertical direction, so that the intermediate light distribution formed by the light reflected by the reflective surface 112 can be projected through the interface 4 and the light exit surface 22 to form a rectangular illumination light shape without entering the light source. The light surface 111 and the reflective surface 112 are specially optically designed to obtain a rectangular intermediate light distribution and then projected by the interface 4 and the light exit surface 22 to form a rectangular lighting light shape, which makes the optical system structure of the optical element of the vehicle light simple. At the same time, if the interface 4 and the light exit surface 22 are both convex curved surfaces that are the same as the light exit surface of the convex lens, their ability to deflect light in all directions is relatively large. In the process of designing the light distribution, it is necessary to take into account the The light distribution process requires repeated adjustment of the surface shapes of the two surfaces, and the light distribution process is complicated. Using the optical element of the vehicle light of the present invention, the interface 4 Both the light-emitting surface 22 and the light-emitting surface 22 have a single-direction dimming function, and the surface shapes of the two optical surfaces can be adjusted independently, which greatly simplifies the dimming steps in the light distribution process.

In the present invention, the light emitting surface 22 can also be set to other curved surface structures, specifically, it can be a convex lens surface as shown in FIG.

In the present invention, the light incident surface 111 can be set as a plane or a curved surface. Preferably, the light incident surface 111 is provided with a curved surface that protrudes toward the side away from the reflection surface 112 , so that the light source 3 incident on the light incident surface 111 is provided with a curved surface. Convergence of light is better.

When the optical element of the vehicle light of the present invention is applied to ordinary high beam lighting or adaptive (ADB, Adaptive Driving Beam) high beam lighting, it generally needs to form the lower boundary of the high beam shape. When applied to low beam lighting, It is generally necessary to form the upper boundary of the low beam shape. Preferably, referring to FIG. 1 , FIG. 15 and FIG. 26 , the end of the reflection surface 112 close to the light incident surface 111 corresponding to the reflection surface 112 is provided with a cut-off line structure 113 ; or, referring to FIG. 41 , the front end of the first optical channel 12 A cutoff line structure 113 is provided. Specifically, when the reflection surface 112 is a paraboloid or a paraboloid-like surface, the cut-off line structure 113 may be disposed at the intersection of the light incident surface 111 and the reflection surface 112 .
