单一光源实现厚壁和内透镜表面花纹双重点亮效果的车灯Single light source realizes double lighting effect of thick wall and inner lens surface pattern

技术领域technical field

本实用新型涉及汽车照明技术领域，具体涉及一种利用单一光源实现厚壁和内透镜表面花纹双重点亮效果的车灯。The utility model relates to the technical field of automobile lighting, in particular to an automobile lamp which utilizes a single light source to realize the double lighting effect of a thick wall and a surface pattern of an inner lens.

背景技术Background technique

厚壁和内透镜在汽车车灯中应用较为广泛，两者都能实现光线的折射和传导。其中光线在厚壁中的传递路径通常如CN20517425U、CN208832369U、CN209026739U、CN208886660U等所述，光源发出的光经厚壁的反射面反射后穿过厚壁，从厚壁一端的出光面或侧面射出。Thick walls and inner lenses are widely used in automotive lamps, both of which can refract and transmit light. The transmission path of light in the thick wall is usually as described in CN20517425U, CN208832369U, CN209026739U, CN208886660U, etc. The light emitted by the light source is reflected by the reflective surface of the thick wall, passes through the thick wall, and exits from the light-emitting surface or side of one end of the thick wall.

市面上常见的汽车尾灯通常具有厚壁结构。除此之外，平面内透镜及其表面集成的装饰花纹也能实现较好的汽车尾灯点亮效果。目前汽车尾灯的厚壁和内透镜两种结构往往相互独立，使得点亮效果较为单一，缺乏辨识度和设计感。并且这两种结构在实现过程中一般需要配套独立的光源，简单将其组合起来不仅成本相对较高而且有一定难度。Common automotive taillights on the market usually have thick-walled structures. In addition, the in-plane lens and the decorative pattern integrated on its surface can also achieve a better lighting effect of automobile taillights. At present, the two structures of thick wall and inner lens of automobile taillights are often independent of each other, which makes the lighting effect relatively simple and lacks recognition and design sense. In addition, these two structures generally need to be matched with independent light sources in the implementation process, and simply combining them is not only relatively expensive but also difficult.

具体实施方式Detailed ways

为使本领域普通技术人员充分理解本实用新型技术方案和有益效果，以下结合具体实施例进行进一步说明。In order to make those of ordinary skill in the art fully understand the technical solutions and beneficial effects of the present invention, further description will be given below in conjunction with specific embodiments.

如图1-5所示的一种尾灯转向灯，其外观为带一定弧度的细长条状。该尾灯转向灯主要包括由外而内布置的转向灯厚壁、支架、转向灯内透镜(双色)以及PCB板，其中转向灯厚壁为传统的侧进光式厚壁，转向灯内透镜为底部进光式。转向灯厚壁和转向灯内透镜分别固定在支架两侧，PCB板固定在前者形成的装配体上，最后整体安装在车身上并与汽车电路相连。在PCB板外表面上设置有LED光源，该光源位置正对转向灯厚壁端部的导光柱以及转向灯内透镜的进光端部。A taillight turn signal as shown in Figure 1-5, its appearance is a slender strip with a certain arc. The taillight turn signal mainly includes a turn signal thick wall, a bracket, a turn signal inner lens (two colors) and a PCB board arranged from the outside to the inside, wherein the turn signal thick wall is a traditional side light type thick wall, and the turn signal inner lens Bottom entry. The thick wall of the turn signal and the inner lens of the turn signal are respectively fixed on both sides of the bracket, the PCB board is fixed on the assembly formed by the former, and finally the whole is installed on the body and connected with the car circuit. An LED light source is arranged on the outer surface of the PCB board, and the position of the light source is directly opposite to the light guide column at the thick wall end of the turn signal and the light entrance end of the inner lens of the turn signal.

当开启转向灯时，LED光源点亮并闪烁，其发出的大部分直射光线穿过转向灯厚壁上的导光柱后，被反射面反射改变方向，最后从转向灯厚壁的端部出光口射出(图4)，实现第一重点亮效果。与此同时，该LED光源发出的部分斜射光线从转向灯内透镜靠近光源的端部进入，经转向灯内透镜表面的若干组细长条状花纹折射后射出，实现第二重点亮效果。在这个过程中，光源发出的其他光线被设置在转向灯内透镜出光面以外部分的遮蔽饰圈挡住，不会散射出去影响点亮效果；转向灯内透镜、转向灯厚壁上无光学花纹区域发生镜面反射，因而也无光线射出。综合来看，同一光源不同的点亮方式实现了双重点亮效果，最大限度的利用了光源发出的光线，使得该尾灯转向灯视觉上呈现出空间立体感，辨识度也更高。When the turn signal is turned on, the LED light source lights up and flashes, most of the direct light emitted by it passes through the light guide column on the thick wall of the turn signal, and is reflected by the reflective surface to change its direction, and finally exits from the end of the thick wall of the turn signal. Shoot out (Figure 4) to achieve the first point highlighting effect. At the same time, part of the oblique light emitted by the LED light source enters from the end of the inner lens of the turn signal close to the light source, and is refracted by several groups of slender striped patterns on the surface of the inner lens of the turn signal, so as to achieve the second key lighting effect. In this process, the other light emitted by the light source is blocked by the shielding ring set outside the light-emitting surface of the inner lens of the turn signal, and will not scatter out to affect the lighting effect; there is no optical pattern area on the inner lens of the turn signal and the thick wall of the turn signal. Specular reflection occurs, so no light is emitted. On the whole, the different lighting methods of the same light source achieve a double lighting effect, maximizing the use of the light emitted by the light source, so that the taillight turn signal visually presents a three-dimensional sense of space, and the recognition degree is also higher.

目前该款车灯已完成开发测试，即将随着某主机厂新车型大量上市。相比于传统实现类似效果的内透镜光顺平面+喷漆镭雕或者双色注塑方案而言，本实用新型方案更加简单、成本也更低。At present, the development and testing of this lamp has been completed, and it will be launched in large quantities with the new models of an OEM. Compared with the traditional inner lens smoothing plane + paint radium engraving or two-color injection molding solution that achieves similar effects, the solution of the present invention is simpler and lower in cost.
