Description

LED light guide strip for car lights

technical field

The utility model relates to an automobile lamp, in particular to an LED light guide strip for the automobile lamp.

Background technique

The light guide strip is a flexible transparent light guide material made by filling a soft nano material in the fluororesin tube, which can be divided into side light guide strips and end light guide strips. Among them, the side light guide strip not only transmits the transmitted light from the incident end surface of the light guide strip to the exit end surface during the transmission process of the light guiding the light guide strip, but also transmits a part of the light from the cladding layer of the light guide strip, so that the whole The light guide strips form a circle of halo to achieve the effect of glare. In addition, it can also change into various colors as the color of the incoming light source changes. The end light guide strip is two end surface light guides.

LED is a low-field electronic semiconductor light-emitting device, which can directly convert electrical energy into light energy. With the advantages of energy saving and environmental protection, high brightness, long service life, strong shock resistance, and less maintenance, it has been widely used in lighting, backlight, landscape decoration, traffic lights and other fields.

In the application of LED and light guide technology, there are currently cases of using multiple LEDs in series to make car lights, and there are also cases of combining LED technology and light guide technology to design LED light guide light source devices for scanning. The case of arranging multiple LEDs on the body of the light strip, and then inlaying the strip body on the object to make a light source, these existing LED and light guide strip application technologies, or the light utilization efficiency of the light guide strip is not high, and need More single LED light sources are used to increase the power consumption; or the light from each part of the light guide strip is not uniform enough, and the scattered light becomes less beautiful. Therefore all there are some deficiencies.

Utility model content

The purpose of the utility model is to provide an LED light guide strip for automobile lights that overcomes the above-mentioned disadvantages, has high light utilization rate, uniform light emission and good light effect.

The technical solution for realizing the purpose of the utility model is: an LED light guide strip for automobile lights, which has a light guide body and LED lamp beads arranged at both ends of the light guide body; the light guide body has a cylindrical light guide body and a convex prism arranged at the bottom of the light guide.

The light guide body and the convex body of the light guide body of the LED light guide strip for automobile lamps are integrated into one piece.

The convex body of the above-mentioned LED light guide strip for automobile lamps is a plane convex platform on which triangular convex ribs are evenly arranged at intervals.

The distance between the convex ribs of the above-mentioned LED light guide strip for automobile lamps is 1.5 mm.

The light guide body of the above-mentioned LED light guide strip for automobile lights is formed by the intersection of two cylindrical light guide bodies, and each light guide body is provided with a convex prism at the bottom.

The utility model has positive effects: the light guide strip of the utility model is made of a structure combining arc surfaces and convex ribs, which increases the refraction surface of light, and a part of the light beam is emitted from the arc surface of the light guide strip, increasing the light guide strip. The light output rate of the circular arc surface, and another part of the light beam is reflected by the convex ribs at the bottom of the light guide strip, which effectively improves the light utilization rate and achieves the effect of uniform light emission, which has high practicability.
