技术领域technical field
本发明涉及车灯,具体地,涉及一种远近光一体光学装置。本发明还涉及一种汽车照明装置和一种汽车。The present invention relates to a vehicle lamp, in particular to an integrated optical device for far and near light. The invention also relates to an automobile lighting device and an automobile.
背景技术Background technique
在不同国家和地区使用的车辆,存在左驾和右驾的不同。因为左驾和右驾的区别,不同国家和地区的法规对车灯的要求也不一致,这种区别体现在近光截止线上时,左驾车辆的近光截止线形状右高左低,而右驾车辆的近光截止线形状左高右低。随着汽车工业和国际经济的发展,汽车行业的国际化程度日益增强,车灯作为汽车的照明装置,是汽车目前以及未来一段时间不可或缺的重要零部件。为了满足国际市场的需求,汽车照明装置需满足不同国家和地区的照明需求。Vehicles used in different countries and regions are different from left-hand drive and right-hand drive. Because of the difference between left-hand drive and right-hand drive, the regulations of different countries and regions have inconsistent requirements for headlights. This difference is reflected in the low beam cut-off line. The shape of the low beam cutoff line of right-hand drive vehicles is high on the left and low on the right. With the development of the automobile industry and the international economy, the internationalization of the automobile industry is increasing day by day. As the lighting device of the automobile, the lamp is an indispensable and important part of the automobile at present and in the future. In order to meet the needs of the international market, automotive lighting devices need to meet the lighting needs of different countries and regions.
为了实现左驾和右驾的前照灯功能,通常是针对不同国家或地区的不同需求,进行设计不同的左驾前照灯或右驾前照灯,因为左驾前照灯只能应用于左驾市场,而右驾前照灯只能应用于右驾市场,这就导致了产品的通用性较差。现有的集成有左驾和右驾功能的前照灯,通常通过遮光板、转轴和电磁阀等转动机构的旋转实现光形切换,这样的光形切换方式的噪音大、造型灵活性低、系统构成较复杂。而且,机械式的切换结构体积较大,不仅影响车灯体积的小型化,还容易对远近光一体车灯的远光光路造成干扰。In order to realize the headlight function of left-hand drive and right-hand drive, different left-hand drive headlights or right-hand drive headlights are usually designed for different needs of different countries or regions, because left-hand drive headlights can only be applied to Left-hand drive market, and right-hand drive headlights can only be used in the right-hand drive market, which leads to poor product versatility. Existing headlamps with integrated left-hand drive and right-hand drive functions usually realize light-shape switching through the rotation of rotating mechanisms such as visors, shafts, and solenoid valves. Such light-shape switching methods have high noise, low modeling flexibility, and The system composition is more complicated. Moreover, the mechanical switching structure has a large volume, which not only affects the miniaturization of the volume of the lamp, but also easily interferes with the high beam light path of the integrated high beam and low beam lamp.
近来也出现了一种同时设置相互独立的辅助近光模块、主近光模块和远光模块的远近光一体车灯,该远近光一体车灯由辅助近光模块形成近光展宽照明,主近光模块形成左驾截止区照明或者右驾截止区照明,两者相互组合形成左驾近光光形,或者右驾近光光形,由远光模块形成远光光形。但该远近光一体车灯中的辅助近光模块、主近光模块和远光模块通常分别设置,使得车灯的体积较大,难以满足当今车灯小型化的要求。为了减小体积,需要将辅助近光模块、主近光模块和远光模块位置设置得很近,而如果将近光展宽照明的 光学元件、左右驾截止区照明的光学元件和远光照明的光学元件紧贴在一起,不同光学元件中的光线会有部分进入其它光学元件中,对近光光形,特别是明暗截止线形成不良影响。Recently, there has also been a kind of high and low beam integrated vehicle lamp with independent auxiliary low beam module, main low beam module and high beam module at the same time. The light module forms the left-hand drive cut-off area illumination or the right-hand drive cut-off area illumination, and the two are combined with each other to form a left-hand drive low-beam light shape, or a right-hand drive low-beam light shape, and the high beam module forms a high beam light shape. However, the auxiliary low-beam module, the main low-beam module and the high-beam module in the high and low beam integrated vehicle lamp are usually arranged separately, which makes the volume of the vehicle lamp relatively large, and it is difficult to meet the requirements of the miniaturization of today's vehicle lamps.

The first light incident part 11 , the first light passing part 12 and the first light emitting part 13 are connected in sequence to form a first light channel. The second light incident portion 21 , the second light passing portion 22 and the second light exit portion 23 are connected in sequence to form a second light channel; the third light incident portion 31 , the third light passing portion 32 and the third light exit portion 33 They are connected in sequence to form a third optical channel. In addition, the first light passing portion 12 , the second light passing portion 22 and the third light passing portion 32 are arranged in sequence from top to bottom, and constitute the light guide portion of the integrated optical device for far and near light of the present invention. The lower side of the second light-passing part 22 is provided with a cut-off line structure 24 recess extending back and forth. The cut-off line structure 24 is recessed in the middle of the second light-passing part 32 in the left-right direction, and has a cut-off line corresponding to the low beam shape. The boundary corresponding to the shape; the corresponding position on the upper side of the third light-passing portion 32 is provided with a convex structure 34 that is consistent with the shape and size of the recess of the cut-off line structure 24 . In this way, after the integrated optical device for far and near light of the present invention is integrally formed, the protruding structure 34 is located in the cut-off line structure 24 inside the second light passing portion 22, and forms a close contact therebetween.

The clear upper boundary of the illumination area, on the other hand, can prevent the light in the first light-passing portion 12 from irradiating the second illumination area and affect the clarity of the cut-off line in the second illumination area. When the light transmitted from the second light-passing part 22 is irradiated to the first material interface 4 , part of the light can be refracted at the first material interface 4 to enter the first light-passing part 12 and exit from the first light-exiting part 13 After being emitted, after being projected by the converging optical element, an overlapping portion between the first lighting area and the second lighting area is formed, so as to prevent a dark area from being formed between the first lighting area and the second lighting area.

The second light incident part 21 , the second light passing part 22 and the second light exit part 23 are all made of the second light guide body 2 , the third light entrance part 31 , the third light passing part 32 and the third light exit part The parts 33 are all made of the third light guide body 3 , and the entire optical device for far and near light is integrally formed. In this way, the first light incident portion 11 , the first light passing portion 12 and the first light exit portion 13 are made of the same material, and there is no space between the first light incident portion 11 , the first light passing portion 12 and the first light exit portion 13 . Interface; the second light incident part 21, the second light passing part 22 and the second light exit part 23 are also made of the same material, the second light incident part 21, the second light passing part 22 and the second light exit part 23 There is no interface between them; similarly, the third light incident part 31, the third light passing part 32 and the third light exit part 33 are also made of the same material, the third light incident part 31, the third light passing part 32 and the third light There is also no interface between the three light-emitting parts 33 . In this way, when the light passes through the corresponding light channel, no reflection is generated due to the interface, and the light efficiency of the light passing through the light channel is high.
作为本发明的远近光一体光学装置的一种具体实施方式,第一入光部11、第二入光部21和第三入光部31均由同一种导光体成型。该导光体可以使用第一导光体1、第二导光体2或者第三导光体3中的一种,也可以使用另一种不同的导光体。第一入光部11、第二入光部21和第三入光部31可以优选使用硅胶材料的导光体,硅胶材料的耐温性能较好,而入光部距离光源较近,承受的温度较高,使用硅胶材料能够防止入光部在较高的工作温 度下发生变形或者老化,能够保障出射光形的稳定性并延长该远近光一体光学装置的使用寿命。另外,由于入光部的结构通常比较复杂,第一入光部11、第二入光部21和第三入光部31均由同一种材料制成,第一入光部11、第二入光部21和第三入光部31就可以一次注塑成型,简化了本发明的远近光一体光学装置的加工工艺,降低了加工成本。As a specific embodiment of the integrated optical device for far and near light of the present invention, the first light incident portion 11 , the second light incident portion 21 and the third light incident portion 31 are all formed by the same light guide body. The light guide body may use one of the first light guide body 1 , the second light guide body 2 or the third light guide body 3 , or may use another different light guide body. The first light incident part 11 , the second light incident part 21 and the third light incident part 31 can preferably use a light guide body made of silica gel material. The temperature is high, and the use of silicone material can prevent the light incident part from being deformed or aged at a high working temperature, which can ensure the stability of the output light shape and prolong the service life of the integrated optical device for far and near light. In addition, since the structure of the light incident portion is usually complicated, the first light incident portion 11 , the second light incident portion 21 and the third light incident portion 31 are all made of the same material. The light portion 21 and the third light incident portion 31 can be injection-molded at one time, which simplifies the processing technology of the integrated optical device for far and near light of the present invention, and reduces the processing cost.

The convex structure 34 formed by the third light guide body 3 is formed by the same light guide body as the third light passing portion 32 , so it can be processed at one time, and the processing and forming are more convenient. At the same time, since the refractive index of the third light guide body 3 is smaller than that of the second light guide body 2 used in the second light passing portion 22 , the light in the second light passing portion 22 is irradiated between the cut-off line structure 24 and the protruding structure 34 . Total reflection can be generated when the interface between them is formed, which improves the light shielding effect of the cut-off line structure 24 .
