Description

Array Light Curtain Lights

technical field

The utility model relates to the field of automobile manufacturing, more particularly, to a lighting assembly of automobiles.

Background technique

General car headlights include high beams, low beams, turn signals, daytime running lights, corner lights, and position lights. Among them, high beams, low beams, turn signals and corner lights are functional lights, which are mainly used to realize road lighting, steering and auxiliary steering. Daytime running lights and position lights belong to decorative lights and indicator lights. Function lights such as high beams, low beams, turn signals and corner lights are turned on when needed and turned off at ordinary times. Decorative lights and indicators such as daytime running lights and position lights are turned on when the vehicle is started, which has a good degree of recognition and decoration. Daytime running lights and position lights have gradually become an important part of vehicle exterior design, playing an increasingly significant role in brand promotion and model identification, so they are widely valued by various car companies.

For decorative lights and indicator lights, LEDs are currently mainly used as light sources. The lighting effects are mainly achieved in the following two ways:

The first way is the solution of LED light source and reflector. Figures 1a and 1b are schematic diagrams showing the structure of an LED light source and a reflector used in the prior art, wherein Figure 1b is a cross-sectional view of Figure 1a along the A-A direction. As shown in Figures 1a and 1b, in this solution, the LED assembly 101 is mounted on top. The LED assembly 101 is composed of a circuit board (PCB board) and an LED light source mounted on the PCB board. A reflection bowl 102 is arranged at the rear of the lamp body. The reflection bowl 102 reflects the light emitted by the LED light source to the front, that is, toward the front of the vehicle lamp. To achieve the optical effect of an array or lattice, it is necessary to arrange an array of LED light sources inside the lamp body, and to precisely design and process the shape, size and position of the reflective bowl to obtain the display effect of the reflected array light source. This solution requires a large space for arranging the LED array and the reflecting bowl, which makes the overall volume of the lamp body large, which is not conducive to cost control and space utilization. In addition, the optical effect directly formed by the reflection of the reflecting bowl is unstable, and there are inevitable assembly errors during the processing and installation of the reflecting bowl, so that the final actual optical effect is often different from the design effect.

The second way is the solution of LED light source and light guide. Figures 2a and 2b are schematic diagrams showing the structure of the LED light source used in the prior art and the light guide, wherein Figure 2b is a cross-sectional view of Figure 2a along the A-A direction. As shown in Figures 2a and 2b, in this solution, the LED light source is arranged at one end of the light guide 201, and the light guide 201 is fixed at a required position on the lamp body through the light guide brackets 202 and 203. When the LED light source is lit, the light is transmitted through the light guide, and the position of the light guide will emit light, thereby achieving a strip-shaped optical effect. The light guide has good flexibility and can be designed into various line shapes such as arcs, straight lines, and broken lines, and the light guide will homogenize the light, making the displayed optical effect more uniform. But the drawbacks of using the light guide scheme are also significant. First of all, the cost is high. The installation of the light guide needs to install the light guide bracket first. The material cost and construction cost are high, and it can only be applied to high-end models. Secondly, the light guide is mainly used for the optical effect of the line type, and the optical effect of the lattice cannot be realized, and it also has great limitations in optical modeling.

To sum up, the decorative lamps and indicator lights using LEDs as light sources in the prior art have certain limitations in terms of cost and flexibility of optical modeling, and cannot fully meet market demands.
