Description

Reflective LED headlights

technical field

The utility model relates to an LED car light, in particular to an LED car light with adjustable light color, so that the car light has functions such as a headlight, a fog light, a direction light or a brake light.

Background technique

At present, LEDs are widely used as lighting sources in lamps because of their advantages of high brightness, power saving, and small size.

Due to the large size of taillights and brake lights, more LED point light sources are required. For common LED point light sources, it is nothing more than a reflective design. As shown in FIG. 7, it is a schematic structural diagram of a point light source 50. It mainly includes:

A reflector 51, the inner layer of which is a reflective material for reflecting the light source;

An LED light source 52 is fixed on the reflector 51, and the light is concentrated and emitted forward through the reflector 51; and

A front cover 53 covers the opening at the front end of the reflector 51, and it can be adjusted to use a convex lens, a semi-convex lens or a plane lens etc. according to the desired light shape of the car light.

Just as the design description of the point light source, the light-emitting surface of the LED light source 52 is set forward, so that the light source can emit in the direction of the front cover 53, and part of the side light is reflected by the reflector 51 and then emitted forward. The intensity of the light Because part of the light is emitted forward after being reflected by the reflector 51, the light intensity of the car lamp is relatively low.

Since the design of the headlight needs to control the light shape of the light emitted, currently LED headlights are rarely used in headlight products, and some manufacturers have proposed to use the current LED taillight design to improve the design of the headlight structure. Since the light shapes of the LED point light sources are the same, it is quite difficult to directly control the light shape of the LED point light sources to comply with the regulations. Therefore, as shown in Figure 8, a plurality of LED point light sources 50 are arranged in a matrix shape, and then A mask 60 is placed under the light emitting surface of the point light source 50 to achieve the purpose of correcting the light emitting shape of the headlight so as to comply with relevant laws and regulations.

Although this headlight can meet the requirements through the use of the mask, it will increase the design and production cost structurally because of the increase of the mask.

Contents of the invention

Therefore, the main purpose of the present utility model is to provide a reflective LED vehicle light, which has a simple structure and high light extraction efficiency, and is suitable for the design of headlights or fog lights.

To achieve the above purpose, the main technical means used by the utility model are as follows:

A reflective LED car light, which is composed of multiple reflective LED point light sources, wherein the LED point light source is mainly designed with a reflector with a diamond curved surface, and an LED light source is fixed on the reflector so that its light-emitting surface faces The diamond curved surface of the reflector is finally covered with a reflector at the front opening of the reflector. In this way, when the LED light source emits light, it will be concentrated backwards and emitted to the front opening after unified refraction by the diamond curved surface to improve the light output efficiency. Since all light sources are refracted by the diamond curve and then emitted, the utility model can be changed by changing the diamond The curvature/area/arrangement of the curved surface can adjust the light shape of the light. Therefore, when the utility model is applied to the production of headlights with standardized light shapes, the diamond curve can be designed to meet the light shape of the light. Relevant regulations, while exempting other light shape correction auxiliary structures, help to simplify the structure and production cost of the overall car lights.

Detailed ways

First please refer to Fig. 1 and shown in Fig. 2, it is a preferred embodiment of a reflective point light source 10, and it comprises:

A reflector 11, an arc reflector 111 is formed on its back, and the inner surface of the arc reflector 111 is formed as a diamond curved surface 112, as shown in Figure 4, the diamond curved surface 112 is designed according to the light shape of the car lamp curvature, area and arrangement;

An LED light source 12 is fixed on the reflector 11, and its light-emitting surface faces the rear arc reflector 111 of the reflector 11. It mainly includes a positioning seat 121 and an LED element 122, and the LED element 122 is fixed on the reflector 11. On the positioning seat 121, the positioning seat 121 is fixed on the arc reflector 111 of the reflector 11 (shown in Figure 3); and

A lampshade 13 covers the front opening 113 of the reflector 11 .

Please refer to FIG. 3 , which is a partial side sectional view of the assembled point light source 10. It can be seen from this figure that since the light-emitting surface of the LED light source 12 is directly facing the diamond curved surface 112 of the arc-shaped reflector 11, the LED light source 12 All the light will be focused on the diamond curved surface 112, and then the diamond curved surface 112 will reflect all the light sources to the front lampshade 13 at one time, so that the light output efficiency is improved.

As shown in Figure 4 again, it is the connection relationship between the LED light source 12 and the arc-shaped reflector 111 diamond curved surface 112. The diamond curved surface 112 is designed according to the light shape specified by the headlight and far light, and the lower right corner forms three inclined curved surfaces A/ B/C, to modify the light shape of the emitted light source as shown in Figure 9, so that the mask structure can be dispensed with, and the overall car light structure is simplified, which helps to simplify the processing procedure and reduce the production cost.

Please refer to Fig. 5 again, which is a reflective car lamp 20 composed of point light sources 10 of the present invention, that is, the above-mentioned point light sources 10 are grouped and arranged together to form a large-sized headlight 30 design, cooperating with the figure As shown in 6, since the light shape of each reflective point light source 10 has already met the light shape requirements of the headlight 30, in this embodiment, as long as it is matched with an appropriate arrangement, it can be easily controlled when all the point light sources 10 are lit. The light shape of the light can meet the headlight shape regulations.

It can be seen from the above description that the utility model designs a reflective point light source that is easy to manufacture headlights. Compared with general reflective LED lights, its structure is more simplified and has better light extraction efficiency, which is helpful for LED headlights. physical development.
