Abstract

The utility model relates to a light-guiding rod structure, in particular to a transparent light-guiding rod which comprises a transparent material body, wherein an externally-penetrating hollow light hole is arranged in the transparent material body, the light hole penetrates through a central axis of the transparent material body, and a concave refraction cutting groove is arranged around the outer surface of the transparent material body. The transparent light-guiding rod is arranged on a light tube of a barn lantern and a hand lamp, and light emitted from the light tube through the light hole and the refraction cutting groove is emitted through refraction, thus light condensation effect is achieved.

Description

A kind of transparent light guide rod

Technical field

The utility model relates to a kind of lamp guide structure, is specifically related to a kind of transparent light guide rod.

Background technology

LED is the illumination science and technology of a new generation; First be developed out in generation nineteen fifty; Originally have only after the monochromatic technical limitation with breaking through in 1992, because of its have traditional osram lamp energy-conservation, than long life, brightness decay, volume is littler and can heat production lamp advantage; Gradually incorporate modern's daily life with various attitudes, as display, traffic sign, car light, barn lantern, lantern, etc. lighting device.

The lampshade of need arranging in pairs or groups during as bulb and use is used in use more properly to guide its light, and the guiding device that also need match in LED lamp source can the more effective person of being used utilize its light.Habitual easy guiding device is for to be installed in the LED lamp in the lampshade of acrylic or polycarbonate materials such as (PC), and promptly lampshade is dispersed light source for utilization, and so the divergence of beam angle of this type of guiding device is restricted, and the LED lamp sends that light relatively disperses and be dazzling.

The utility model content

In order to address the above problem, the purpose of the utility model is to provide a kind of optically focused performance light better, that light emitting source is sent softer transparent light guide rod.

To achieve these goals, the technical scheme of the utility model employing is:

A kind of transparent light guide rod comprises a transparent material body, is provided with the light hole of an outer logical hollow in the said transparent material body, and said light hole runs through the central axis of said transparent material body; Be surrounded with the refraction grooving of indent on said this external surface of transparent material.

Preferably, said refraction grooving equidistance is arranged at this external surface of transparent material, said refraction grooving by two fold an angle relative plane of refraction constitute.

The utility model is installed on the light pipe of barn lantern, lantern, the light that light pipe sends is launched through superrefraction, reach the effect of optically focused through light hole and refraction grooving.

The beneficial effect of the utility model is that the light that light emitting source is sent is concentrated more and is softer, protection user eye health.

Description of drawings

Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:

Fig. 1 is the front view of the utility model;

Fig. 2 is the vertical view of the utility model.

Among the figure:

1, transparent material body 11, refraction grooving light hole

111, plane of refraction 12, light hole

Embodiment

To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.

As depicted in figs. 1 and 2, the utility model discloses a kind of transparent light guide rod, comprise transparent material body 1, be provided with the light hole 11 of an outer logical hollow in the transparent material body 1, light hole 11 runs through the axis L of transparent material body 1; Be surrounded with the refraction grooving 12 of indent on said transparent material body 1 outside surface, refraction grooving 12 equidistance are arranged at transparent material body 1 outside surface, said refraction grooving 12 by two fold an angle relative plane of refraction 111 constitute.

When the utility model uses, it is sleeved on the light pipe of barn lantern, lantern etc., the light that light pipe is sent is more concentrated and soft, and is no longer dazzling.

More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.

Claims

1. a transparent light guide rod is characterized in that, comprises a transparent material body, is provided with the light hole of an outer logical hollow in the said transparent material body, and said light hole runs through the central axis of said transparent material body; Be surrounded with the refraction grooving of indent on said this external surface of transparent material.

2. transparent light guide according to claim 1 rod, it is characterized in that: said refraction grooving equidistance is arranged at this external surface of transparent material, said refraction grooving by two fold an angle relative plane of refraction constitute.
