技术领域Technical Field
本发明涉及一种车灯光学组件，特别是一种多功能复合的汽车信号灯光学组件。The invention relates to a vehicle light optical component, in particular to a multifunctional composite vehicle signal light optical component.
背景技术Background Art
汽车前照灯的造型设计越来越小型化，日间行车灯也逐渐成为了汽车的标准配置。如果每一种灯光的照明装置均进行单独设计装配，而各自均需要占用一定的空间，使得整个照明装置将占用较大的空间，这与前照灯越来越窄小的造型设计难以匹配。如果前照灯中具备全部信号灯功能则有利于减小整个灯具的体积，其中一种技术路线是将多种信号灯功能进行复合，即一个光学元件同时用于多种信号灯功能或者多个信号灯功能的部分光路复合到一个光学元件、共用一个出光面。The design of automobile headlights is becoming more and more miniaturized, and daytime running lights have gradually become a standard feature of automobiles. If the lighting device of each light is designed and assembled separately, and each needs to occupy a certain space, the entire lighting device will take up a large space, which is difficult to match with the increasingly narrow design of the headlights. If the headlight has all the signal light functions, it will help to reduce the size of the entire lamp. One of the technical routes is to combine multiple signal light functions, that is, one optical element is used for multiple signal light functions at the same time, or part of the light paths of multiple signal light functions are combined into one optical element and share a light-emitting surface.
现有技术中，公开号为CN112443814A的中国专利公开了一种光导组件，其包括两个导光元件，其中一个导光元件与另一导光元件复合，后一导光元件的出光进入前一导光元件后再由前一导光元件的出光面出射，因此在为两个导光元件配置不同的子光源后可在同一出光面实现两种不同功能的光照。但是采用该技术方案难以实现三个光照功能的集合，如进一步增加导光元件，则光学结构加变得复杂，会占用较大的空间，不能很好地适应越来越小的汽车前照灯空间要求。另外也有现有技术采用多次弯折的一个光学件多处入光实现多种信号灯功能，在配置多功能的灯光时，需要扩展增加更多的弯折光路结构，这样需要占用更大的空间。In the prior art, a Chinese patent with publication number CN112443814A discloses a light guide assembly, which includes two light guide elements, one of which is composited with the other light guide element, and the light from the latter light guide element enters the former light guide element and then is emitted from the light emitting surface of the former light guide element. Therefore, after configuring different sub-light sources for the two light guide elements, two different lighting functions can be realized on the same light emitting surface. However, it is difficult to achieve a combination of three lighting functions using this technical solution. If more light guide elements are added, the optical structure becomes more complicated, which will occupy a larger space and cannot adapt well to the increasingly smaller space requirements for automobile headlights. In addition, there is also prior art that uses an optical component that is bent multiple times to input light at multiple locations to achieve multiple signal light functions. When configuring multifunctional lights, it is necessary to expand and add more bent optical path structures, which requires a larger space.

具体实施方式DETAILED DESCRIPTION
下面结合实施例对本发明作进一步说明，但不作为对本发明的限定。The present invention will be further described below in conjunction with the embodiments, but are not intended to be limiting of the present invention.
请结合图1至图7所示，本发明实施例涉及的多功能复合的汽车信号灯光学组件，包括第一光源1、第二光源2、第三光源3和条形导光元件4，其中第一光源1为日间行车灯LED，第二光源2为转向灯LED，第三光源3为位置灯LED。条形导光元件4为左右方向延伸的整条呈条形的元件，其可以由透明的PC或PMMA制成，具有良好的光学性能和透光性。Referring to Figures 1 to 7, the multifunctional composite automotive signal light optical assembly according to the embodiment of the present invention comprises a first light source 1, a second light source 2, a third light source 3 and a strip light guide element 4, wherein the first light source 1 is a daytime running light LED, the second light source 2 is a turn signal LED, and the third light source 3 is a position light LED. The strip light guide element 4 is a whole strip-shaped element extending in the left-right direction, which can be made of transparent PC or PMMA and has good optical properties and light transmittance.
条形导光元件4具有多个侧部和两个端部，即条形导光元件4上围绕其长度方向的轴线所设置的各个面为侧部，而轴线穿过的面为端部。在条形导光元件4的这些侧部分别设置有第一入射部401、入射反射部402、反射部403以及出光部404，在条形导光元件4的一个端部则设置为第二入射部405。第一光源1设置在第一入射部401的位置，第一光源1的光线通过第一入射部401后进入条形导光元件4，然后由反射部403将进入条形导光元件4的第一光源1的光线反射向出光部404，最终通过出光部404出射形成日间行车灯的光线。第二光源2设置在第二入射部405的位置，第二光源2的光线通过第二入射部405后进入条形导光元件4，然后由入射反射部402将进入条形导光元件 4的第二光源2的光线反射向出光部404，最终通过出光部404出射形成位置灯的光线。第三光源3设置在入射反射部402的位置，第三光源3的光线通过入射反射部402进入条形导光元件4后直接射向出光部404，由出光部404出射形成转向灯的光线。由此，第二光源2和第三光源3的光线将共用入射反射部402，一面多用，提高结构利用率。The strip-shaped light guide element 4 has a plurality of side portions and two ends, that is, the surfaces arranged around the axis in the length direction of the strip-shaped light guide element 4 are the side portions, and the surface through which the axis passes is the end portion. The first incident portion 401, the incident reflection portion 402, the reflection portion 403 and the light emitting portion 404 are respectively arranged on these side portions of the strip-shaped light guide element 4, and the second incident portion 405 is arranged at one end of the strip-shaped light guide element 4. The first light source 1 is arranged at the position of the first incident portion 401, and the light of the first light source 1 enters the strip-shaped light guide element 4 after passing through the first incident portion 401, and then the light of the first light source 1 entering the strip-shaped light guide element 4 is reflected by the reflection portion 403 toward the light emitting portion 404, and finally emitted through the light emitting portion 404 to form the light of the daytime running light. The second light source 2 is arranged at the position of the second incident portion 405. The light of the second light source 2 enters the strip light guide element 4 after passing through the second incident portion 405. Then, the incident reflection portion 402 reflects the light of the second light source 2 entering the strip light guide element 4 toward the light exit portion 404, and finally, the light of the position light is emitted through the light exit portion 404. The third light source 3 is arranged at the position of the incident reflection portion 402. The light of the third light source 3 enters the strip light guide element 4 through the incident reflection portion 402 and directly emits toward the light exit portion 404. The light of the turn signal light is emitted from the light exit portion 404. Thus, the light of the second light source 2 and the third light source 3 will share the incident reflection portion 402, and one surface can be used for multiple purposes, thereby improving the structural utilization rate.
在本具体实施例中，条形导光元件4的顶面设置为第一入射部401，前侧面设置为出光部404，在后侧面和底面之间设置一个与顶面倾斜相对的弯曲弧面构成反射部403。为了使日间行车灯能形成一个窄长的出光效果，第一光源1是沿着条形导光元件4的长度方向间隔设置多个。In this specific embodiment, the top surface of the strip-shaped light guide element 4 is set as the first incident portion 401, the front side surface is set as the light emitting portion 404, and a curved surface obliquely opposite to the top surface is set between the rear side surface and the bottom surface to constitute the reflecting portion 403. In order to enable the daytime running light to form a narrow and long light emitting effect, a plurality of first light sources 1 are arranged at intervals along the length direction of the strip-shaped light guide element 4.
并且为了提高日间行车灯的出光亮度，使其具有更远的照射范围，在第一入射部401 设置了多个聚光杯401a结构，聚光杯401a的出光面紧贴条形导光元件4的顶面设置并朝向反射部403。单个聚光杯401a的具体结构可依照现有技术中车灯的聚光杯结构设置，不再赘述。聚光杯的位置则与第一光源1一一对应。第一光源1发出的光线通过聚光杯401a的整形后使光线更加平行地射向条形导光元件4的反射部403。In order to improve the brightness of the daytime running light and make it have a longer irradiation range, a plurality of focusing cups 401a structures are arranged on the first incident portion 401, and the light emitting surface of the focusing cup 401a is arranged close to the top surface of the strip-shaped light guide element 4 and faces the reflecting portion 403. The specific structure of a single focusing cup 401a can be arranged according to the focusing cup structure of the headlight in the prior art, and will not be described in detail. The position of the focusing cup corresponds to the first light source 1 one by one. The light emitted by the first light source 1 is shaped by the focusing cup 401a so that the light is emitted more parallelly to the reflecting portion 403 of the strip-shaped light guide element 4.
条形导光元件4的反射部403是向条形导光元件4内凹的柱面，出光部404是向外凸的柱面，反射部403的柱面轴线以及出光部404的柱面轴线都与条形导光元件4的长度方向平行。近似平行的第一光源1的光线在投射到反射部403后，由于反射部403是向条形导光元件4内凹的柱面(相对于条形导光元件4的第一光源1的光线是凸面)，光线反射后呈第一的角度发散射向出光部404，再由出光部404形成的凸透镜作用进行聚光射出。为了增强反射部403的反射效果，可以在条形导光元件4的反射部403的外表面涂覆反射层。The reflecting portion 403 of the strip light guide element 4 is a cylindrical surface concave toward the strip light guide element 4, and the light emitting portion 404 is a cylindrical surface convex toward the outside. The cylindrical axis of the reflecting portion 403 and the cylindrical axis of the light emitting portion 404 are parallel to the length direction of the strip light guide element 4. After the approximately parallel light of the first light source 1 is projected onto the reflecting portion 403, since the reflecting portion 403 is a cylindrical surface concave toward the strip light guide element 4 (relative to the light of the first light source 1 of the strip light guide element 4, which is a convex surface), the light is reflected and scattered toward the light emitting portion 404 at a first angle, and then the convex lens formed by the light emitting portion 404 is used to focus and emit. In order to enhance the reflection effect of the reflecting portion 403, a reflecting layer can be coated on the outer surface of the reflecting portion 403 of the strip light guide element 4.
条形导光元件4的端面设置为第二入射部405，条形导光元件4的后侧面为入射反射部402，端面与该后侧面形成一个角度使得从端面入射的光线在经过后侧面的反射后能从前侧面出射形成位置灯。The end face of the strip light guide element 4 is set as the second incident part 405, and the rear side surface of the strip light guide element 4 is the incident reflection part 402. The end face and the rear side surface form an angle so that the light incident from the end face can be emitted from the front side surface after being reflected by the rear side surface to form a position light.
为了使转向灯更具线条感而提高转向的指向性观感，可以将第三光源3设置为沿条形导光元件4的长度方向间隔排列的多个，同时可以将入射反射部402设为锯齿结构，锯齿结构包括沿条形导光元件4的长度方向交替排列的第一齿面402a和第二齿面402b，第一齿面402a和第二齿面402b即形成锯齿面，各个第一齿面402a相互平行设置，各个第二齿面402b也相互平行设置。将第二入射部405设为一平面，其中第二入射部405 以近似垂直于出光部404的方向设置。第二入射部405与第一齿面402a间的夹角为 25°～35°使第一齿面402a得以反射第二光源2发出并进入条形导光元件4的光。在此优选的实施例中，第二入射部405与第一齿面402a间的夹角为30°。第三光源3发出的光则大部分通过第一齿面402a进入条形导光元件4，另有一部分通过第二齿面402b 进入条形导光元件4，这种锯齿结构使得第三光源3进入条形导光元件4的光线得到一定的均匀化处理，使得转向灯效果更佳。In order to make the turn signal more linear and improve the directivity of the turn signal, the third light source 3 can be set to be a plurality of light sources arranged at intervals along the length direction of the strip light guide element 4, and the incident reflection part 402 can be set to a sawtooth structure, which includes a first tooth surface 402a and a second tooth surface 402b arranged alternately along the length direction of the strip light guide element 4, and the first tooth surface 402a and the second tooth surface 402b form a sawtooth surface, and each first tooth surface 402a is arranged parallel to each other, and each second tooth surface 402b is also arranged parallel to each other. The second incident part 405 is set to a plane, wherein the second incident part 405 is arranged in a direction approximately perpendicular to the light exit part 404. The angle between the second incident part 405 and the first tooth surface 402a is 25° to 35°, so that the first tooth surface 402a can reflect the light emitted by the second light source 2 and entering the strip light guide element 4. In this preferred embodiment, the angle between the second incident part 405 and the first tooth surface 402a is 30°. Most of the light emitted by the third light source 3 enters the strip light guide element 4 through the first tooth surface 402a, and another part enters the strip light guide element 4 through the second tooth surface 402b. This sawtooth structure makes the light from the third light source 3 entering the strip light guide element 4 uniform to a certain extent, making the turn signal effect better.
请结合图8和图9所示，形成日间行车灯、位置灯、转向灯三种汽车前照灯的信号灯的光线路径是这样的。Please refer to FIG8 and FIG9 , the light path of the signal lights forming the three types of vehicle headlights, namely, daytime running lights, position lights, and turn signals, is as follows.
日间行车灯：第一光源1——>聚光杯折射于反射——>反射部403反射——>出光部404Daytime running light: first light source 1 -> focusing cup refracts and reflects -> reflection part 403 reflects -> light emitting part 404
位置灯：第二光源2——>第二入射部405——>入射反射部402的第一齿面402a反射——>出光部404Position light: second light source 2 -> second incident portion 405 -> reflection from first tooth surface 402a of incident reflector 402 -> light emitting portion 404
转向灯：第三光源3——>入射反射部402的第一齿面402a及第二齿面402b折射——>出光部404。Turn signal lamp: the third light source 3 -> the first tooth surface 402 a and the second tooth surface 402 b of the incident reflective portion 402 are refracted -> the light emitting portion 404 .
