Abstract

The utility model discloses a light-gathering structure of a car taillight, which is used to be arranged around the LED light-emitting body of the light. The light-gathering structure includes a central axis and a plurality of light-gathering blocks evenly arranged on the central axis. A space for the LED light-emitting body to pass through is separated between two adjacent light-gathering blocks. A light-gathering surface for gathering light and emitting light is respectively arranged on two sides of the light-gathering block perpendicular to the central axis. The light emitted by the LED light-emitting body is gathered on the light-gathering surface, and the light is reflected by the light-gathering surface, so as to improve the utilization rate of the emitted light and enhance the lighting brightness.

Description

Concentrating structure of automobile tail light

technical field

The utility model relates to a lamp for motor vehicle illumination, in particular to a light-gathering structure of an automobile tail lamp for automobile illumination.

Background technique

Car lights are various traffic lights installed on cars to ensure safe driving. It is an important part in car production, and car tail lights are one of the car lights. Car tail lights include turn signals, brake lights, position lights, rear fog lights, reversing lights, and parking lights. As LEDs are used as a green, energy-saving solid-state light source in the lighting field, more and more automotive lights also use LEDs as light sources. However, using LED as a light source also has some disadvantages, such as relatively low brightness. Compared with ordinary light sources, the luminous efficiency per watt of LED is many times higher, but the brightness is still relatively low from the perspective of the whole lamp. Especially when LEDs are used in automobile taillights, if the lighting brightness is not enough, it will affect the safety of drivers, and may even cause traffic accidents.

Therefore, when using LEDs as the light source of automobile tail lights, how to solve the problem of the brightness of LEDs is a technical problem to be solved urgently in the industry.

Contents of the invention

The main purpose of the utility model is to provide a light-gathering structure of an automobile taillight, aiming at realizing a simple structure of the light-gathering structure of an automobile taillight, so that the light emitted by an LED illuminant through the light-gathering structure is uniform and soft, and the illumination brightness is enhanced.

The utility model proposes a light-gathering structure of an automobile tail light, which is used to be arranged around the LED luminous body of the lamp. There is a vacancy between the adjacent light-gathering blocks for the LED illuminant to pass through, and two sides perpendicular to the central axis of the light-gathering block are respectively provided with a space for converging light and emitting light. the spotlight surface.

Preferably, the light-gathering surface is inclined.

Each light-gathering block of the utility model is provided with two light-gathering surfaces for converging light and emitting light, and there is a space between two adjacent light-gathering blocks for the LED luminous body to pass through. The first concentrating surface is opposite to the vacancy for the LED luminous body to pass through. If the light concentrating structure is combined with the LED luminous body in the automobile taillight, the LED luminous body placed in the vacant space is surrounded by a concentrating surface to make the LED emit light. The light emitted by the body can be concentrated on the light-gathering surface to the maximum extent, and the light is reflected by the light-gathering surface, which improves the utilization rate of the emitted light and enhances the brightness of the lighting.

Description of drawings

Fig. 1 is a perspective view of an embodiment of a light-gathering structure of an automobile tail light of the present invention.

The realization of the purpose of the utility model, functional characteristics and advantages will be further described in conjunction with the embodiments and with reference to the accompanying drawings.

Detailed ways

It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Referring to FIG. 1 , an embodiment of the light-gathering structure 10 of the automobile tail light of the present invention is proposed, which is used to be arranged around the LED illuminant of the light. The light concentrating structure 10 includes a central axis 100 and several light concentrating blocks 200 uniformly arranged on the central axis 100 . There is a vacancy between two adjacent light concentrating blocks 200 for the LED illuminant to pass through. If the light concentrating structure 10 is combined with the LED illuminant in the automobile taillight, the LED illuminant is placed in this vacancy. On the two sides of the light collecting block 200 perpendicular to the central axis 100 are respectively provided a light collecting surface 201 for collecting light and emitting the light, and the light collecting surface 201 is arranged obliquely. Each concentrating surface 201 is opposite to the vacancy for the LED illuminant to pass through, and the LED illuminant placed in the vacancy is provided with a concentrating surface 201, so that the light emitted by the LED illuminant can be converged to the concentrating surface to the maximum extent. 201, and the light is reflected by the concentrating surface 201, so as to improve the utilization rate of the emitted light and enhance the illumination brightness.

The above are only preferred embodiments of the present utility model, and are not therefore limiting the patent scope of the present utility model. All equivalent structural transformations made by using the utility model specification and accompanying drawings are directly or indirectly used in other related technologies. Fields are all included in the scope of patent protection of the utility model in the same way.
