Description

增加LED后灯外侧视认角亮度的方法及LED后灯Method for increasing the brightness of the external viewing angle of LED rear lights and LED rear lights

技术领域technical field

本发明涉及一种增加LED后灯外侧视认角亮度的方法以及采用该方法实现外侧视认角度增加的LED后灯，属于车灯技术领域。The invention relates to a method for increasing the brightness of the outer viewing angle of an LED rear light and an LED rear light using the method to increase the outer viewing angle, belonging to the technical field of vehicle lights.

背景技术Background technique

在进行灯具光学设计时，要考虑灯具外侧80度视认角的亮度满足法规的要求。目前常用的方式有两种：When carrying out the optical design of the luminaire, it is necessary to consider that the brightness of the 80-degree viewing angle on the outside of the luminaire meets the requirements of the regulations. There are two commonly used methods at present:

1、依靠反射镜高亮镀铝侧壁的反射光1. Rely on the reflected light of the reflector to highlight the aluminum-plated side wall

光源中心直射光经过反射镜高亮镀铝侧壁反射后，抵达法规要求的视认角区域，满足法规对视认角的亮度要求。该方式的局限在于，从灯具外侧看去，需要可见一定面积的反射镜侧壁。当反射镜侧壁由于灯具造型遮挡，而无法露出足够的面积时，外侧视认角区域的亮度将不足以满足法规要求。The direct light from the center of the light source is reflected by the bright aluminum-plated side wall of the reflector, and reaches the viewing angle area required by the regulations, meeting the brightness requirements of the regulations on the viewing angle. The limitation of this method is that, when viewed from the outside of the lamp, a certain area of the side wall of the reflector needs to be visible. When the side wall of the reflector cannot expose enough area due to the shading of the lamp shape, the brightness of the outer viewing angle area will not be sufficient to meet the regulatory requirements.

2、依靠灯具配光镜内表面上的视认角花纹2. Rely on the viewing angle pattern on the inner surface of the light distribution mirror of the lamp

光线经过配光镜内表面的视认角花纹折射，抵达外侧大角度，打亮外侧视认角花纹。该方式的局限在于，在灯具配光镜内表面需要一定区域的视认角花纹，对于造型有较大冲击。且由于外侧视认角角度较大，当灯具配光镜造型曲率较大时，向外侧照的光线容易发生全反射，视认角花纹折射的效果减小，难以满足法规视认角的要求。The light is refracted by the viewing angle pattern on the inner surface of the light distribution mirror, reaches the outer large angle, and brightens the outer viewing angle pattern. The limitation of this method is that a certain area of viewing angle pattern is required on the inner surface of the light distribution mirror of the lamp, which has a great impact on the shape. Moreover, due to the large angle of viewing angle on the outside, when the shape of the light distribution mirror of the lamp has a large curvature, the light shining outward is prone to total reflection, and the effect of the refraction of the pattern on the viewing angle is reduced, which makes it difficult to meet the requirements of the legal viewing angle.

具体实施方式Detailed ways

本发明公开了一种增加LED后灯外侧视认角亮度的方法，是在LED后灯内、从外侧可见的反射镜侧壁边缘靠后的位置另外设置一颗LED，使该颗LED直射光直接照射到法规要求的外侧视认角区域，从而增加视认角区域的亮度。The invention discloses a method for increasing the brightness of the outside viewing angle of an LED rear light. An additional LED is arranged in the LED rear light at a position behind the edge of the side wall of the reflector visible from the outside, so that the LED directly shines on the light. Directly illuminate the outer viewing angle area required by regulations, thereby increasing the brightness of the viewing angle area.

采用该方法，如图1所示，本发明所公开的LED后灯包括灯体6、LED、设置LED的线路板1、反射镜3和配光镜5，所述配光镜安装在所述灯体上，并与所述灯体围成灯腔，所述线路板和反射镜位于灯腔内，且均固定在所述灯体上，所述反射镜呈碗状，其侧壁反射面朝向所述配光镜，所述LED位于所述反射镜的底部中心，且其发光面朝向所述配光镜，所述反射镜的侧壁边缘靠后的位置另外设置一颗LED4，该颗LED的出光面朝向所述配光镜，且光轴方向位于法规要求的外侧视认角区域内，该颗LED也设置在所述线路板上。Using this method, as shown in Figure 1, the LED rear light disclosed by the present invention includes a lamp body 6, LEDs, a circuit board 1 with LEDs, a reflector 3 and a light distribution mirror 5, and the light distribution mirror is installed on the on the lamp body, and forms a lamp cavity with the lamp body, the circuit board and the reflector are located in the lamp cavity, and are fixed on the lamp body, the reflector is bowl-shaped, and the reflective surface of the side wall Facing the light distribution mirror, the LED is located at the bottom center of the reflector, and its light-emitting surface faces the light distribution mirror, and an LED4 is additionally set at the position behind the edge of the side wall of the reflector. The light emitting surface of the LED faces the light distribution mirror, and the direction of the optical axis is located in the outer viewing angle area required by regulations, and the LED is also arranged on the circuit board.

本发明针对的是后灯，因此相对该后灯所称的后方也是该后灯所安装在的车身的前方。The present invention is aimed at the rear light, so the rear referred to relative to the rear light is also the front of the vehicle body on which the rear light is installed.

所述LED后灯还可以包括线路板支架2，所述线路板通过所述线路板支架固定在所述灯体上。The LED rear light may also include a circuit board support 2, and the circuit board is fixed on the lamp body through the circuit board support.

当从外侧可见的反射镜3的侧壁面积有限时，可以通过LED4直射光，将视认角区域打亮，以满足法规要求，因此克服了现有方式1的缺陷。同时，由于本发明所采用的方式不用依赖于配光镜内表面的视认角花纹折射，因此配光镜造型不再受此局限，即使配光镜曲率较大，不会削减视认角区域亮度增加的效果，因此无需担心视认角区域亮度无法满足法规要求。When the area of the side wall of the reflector 3 visible from the outside is limited, the viewing angle area can be illuminated by direct light from the LED 4 to meet the requirements of regulations, thus overcoming the defects of the existing method 1. At the same time, since the method adopted in the present invention does not rely on the refraction of the viewing angle pattern on the inner surface of the photodistributor, the shape of the photodistribution mirror is no longer limited by this. Even if the curvature of the photodistribution mirror is large, the viewing angle area will not be reduced The effect of increased brightness, so there is no need to worry that the brightness of the viewing angle area cannot meet the regulatory requirements.
