Abstract
The utility model relates to field of LED illumination, in particular to a kind of LED reflection shield, comprise reflection shield body, what at least two groups that are provided with described reflection shield body appeared for LED lamp bead goes out lamp hole, it is characterized in that: the inner side of described reflection shield body is provided with reflective membrane, the inner side of described reflection shield body is also provided with the light guide coordinating lamp hole, and described light guide is evenly arranged on relative on the position gone out between lamp hole; Adopt the utility model, by the effect of light guide, enhance the refraction of LED reflection shield, the ability of reflection ray, the uniform light that LED is sent through LED reflection shield, soft, decrease glare, substantially increase the effect of anti-dazzle eye.
Description
Technical field
The utility model relates to field of LED illumination, particularly a kind of LED reflection shield.
Background technology
At present, the solid state light emitter that LED has the advantages such as environmental protection, energy-efficient, long service life as a new generation is more and more extensive in the application of lighting field, but LED is the direct projection light source that a point sends, direction of illumination is single, the central point light that straight line irradiates is very strong, have dazzle, dazzle can accelerate eye strain, and operating efficiency is reduced.Therefore usual all needs when using LED as scattering light source establishes one for the reflection shield of divergent rays at Covers.But the effect of the divergent rays of existing reflection shield is not so good, and the light irradiated out is uneven, easily makes the eyes of people produce tired.
Summary of the invention
The utility model is in order to solve the refraction of LED reflection shield, the ability of reflection ray, the uniform light that LED is sent through LED reflection shield, soft, realizes that light efficiently changes with anti-dazzle
Function, a kind of LED reflection shield, comprise reflection shield body, what at least two groups that are provided with described reflection shield body appeared for LED lamp bead goes out lamp hole, it is characterized in that: the inner side of described reflection shield body is provided with reflective membrane, the inner side of described reflection shield body is also provided with the light guide coordinating lamp hole, and described light guide is evenly arranged on relative on the position gone out between lamp hole.
Preferably, described light guide is polygonal pyramid light guide.
Preferably, described light guide is conical light guide.
Further, the reflection angle of described light guide is designed to 95 ° ~ 115 ° according to the beam angle of LED lamp bead and glare index.
The beneficial effects of the utility model are: adopt the utility model, by the effect of light guide, enhance the refraction of LED reflection shield, the ability of reflection ray, make the uniform light that LED sends through LED reflection shield, soft, especially the luminescent film in the utility model have employed a kind of material (PC) more capable of circulation and combines with other pulp furnish thus rely on self-diffusion to define a kind of optical particle coating adhesion film, reflectivity is more than 100%, the LED light line reflected away is made to become soft further, decrease glare, substantially increase the effect of anti-dazzle eye.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Wherein, 1 is reflection shield body, and 2 for going out lamp hole, and 3 is reflective membrane, and 5 is light guide.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred specific embodiment, the utility model is further described: a kind of LED reflection shield, comprise reflection shield body 1, what at least two groups that are provided with described reflection shield body 1 appeared for LED lamp bead goes out lamp hole 2, the inner side of described reflection shield body 1 is provided with reflective membrane 3, the inner side of described reflection shield body 1 is also provided with the polygonal pyramid light guide 5 coordinating lamp hole 2, described polygonal pyramid light guide 5 is evenly arranged on relative on the position gone out between lamp hole 2, the reflection angle of described polygonal pyramid light guide 5 is designed to 95 ° ~ 115 ° according to the beam angle of LED lamp bead and glare index, the present embodiment have employed 110 °.
Second embodiment, is with the first embodiment difference, have employed conical light guide.
