Description

Light guide rod

Technical Field

The utility model relates to a light guide rod.

Background

The traditional car light generally adopts the halogen lamp, but current halogen lamp life is short, luminous efficacy is low (only 12% -18% can change into light energy, and the rest all scatters and disappears with the form of heat energy), therefore current lighting methods adopts LED lamp cooperation leaded light stick to throw light on, current leaded light stick is the glass material, because processing technology's problem, the leaded light stick of current glass material can only be made into straight tube-shape, and straight tube-shape leaded light stick its upper and lower is the same size, lead to its light-emitting focus and receive the same size of light mask, leaded light performance is poor, can't satisfy the use needs, consequently, need provide the leaded light stick of a big end down shape and solve this problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a light guide rod with a big top and a small bottom;

the light guide rod is composed of a light guide body and a tip part, wherein the light guide body is in a shape with a small upper part and a big lower part, and the light guide rod is made of optical organic silica gel;

furthermore, the lower part of the light guide rod is provided with a limiting part;

further, a reflecting film is plated on the surface of the light guide body;

further, the limiting part is a limiting plate arranged on the light guide body;

further, the limiting plate is circular;

further, the limiting part is a plurality of limiting lugs arranged on the light guide body;

further, the light guide body and the tip part are integrally processed and formed;

the utility model has the advantages of simple structure, processing convenience, leaded light nature are good, compare with current technique, through the leaded light stick comprises light conductor and prong, the light conductor is big end down shape, the leaded light stick is made by optics organic silica gel, and optics organic silica gel can be better process into appointed shape with the leaded light stick to can make big end down shape with the light conductor, can realize that upper portion light-emitting focus is little, and the area of receiving light of lower part is big, and silica gel material easy to assemble location, difficult fracture, production efficiency height in addition, more convenient processing when can improving leaded light nature, it is required to satisfy production and use.

FIG. 3 is a schematic diagram showing a comparison between a straight cylindrical light guide rod and a light guide rod having a large top and a small bottom.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments;

referring to fig. 1-2, a light guide rod, the light guide rod 1 is composed of a light guide body 11 and a tip portion 12, the light guide body 11 is in a shape of a small top and a large bottom, the light guide rod 1 is made of optical organic silica gel, the optical organic silica gel can better process the light guide rod into a specified shape, so that the light guide body can be made into a shape of a small top and a large bottom, namely, a light emitting focus at the upper part is small, a light receiving area at the lower part is large, and the silica gel material is convenient to mount and position, not easy to break, high in production efficiency, capable of improving light guide performance and more convenient to process, and capable of meeting production and use;

referring to fig. 3, under the same light-emitting focus, the silica gel light-guiding rod can make the light-receiving surface large, so that light can be guided better, and the use requirement can be met;

in the utility model, the light guide body 11 is in a conical shape with a small upper part and a big lower part, and the sharp head part 12 is positioned at the upper part of the light guide body 11;

in the utility model, the light conductor 11 is in a shape of small top and big bottom, and the columnar surface thereof is a wavy line;

referring to fig. 1-2, the lower portion of the light guide rod 1 is provided with a limiting portion 13, and the limiting portion 13 is used for being matched with the mounting cover 100 for positioning and mounting, so that the light guide rod is convenient to assemble, disassemble and replace, improves the efficiency, and meets the use requirement;

referring to fig. 1-2, a reflective film is plated on the surface of the light guide body 11, light is transmitted from one end to the other end when the light guide rod is used, and the processing standard of the light guide rod is that the surface of the light guide rod cannot leak light, so that the surface of the light guide rod cannot be guaranteed to be smooth due to the problem of processing precision, and the reflective film can prevent light leakage and reflect illumination back into the light guide rod;
