Abstract

The utility model relates to the technical field of the lighting electric appliance, in particular to an anti-glare LED (Light-Emitting Diode) lamp. The anti-glare LED lamp comprises a reflector and an LED light source located at the bottom of the reflector, a radiator for dissipating heat produced by the LED light source, and an anti-glare shield which is composed of a reflecting convex surface and a support for the sidewalls of the reflecting convex surface, wherein the support is fixed to the front end of the reflector; and the reflecting convex surface is toward the direction of the bottom of the reflector and faces directly the LED light source. The anti-glare LED lamp is characterized in that: the anti-glare shield is arranged in the light emitting direction of the LED light source within the reflector, so that light that the LED light source directly emits outwards can be shielded and the light can be reflected completely through the reflector; in other words, the LED light source is hidden inside the anti-glare shield so that glare is eliminated; therefore, the eyes of consumers are protected against harm and light pollution is reduced.

Description

A kind of glare prevention LED light fixture

Technical field

The utility model relates to the electric lighting technical field, particularly a kind of LED light fixture of anti-dazzle.

Background technology

Led light source can produce dazzle, and human eye is produced injury, therefore need carry out anti-dazzle to led light source and handle, and the supporting anti-dazzle measure of led light source now has following several kinds:

1, install the printing opacity diffuser plate additional, the light that like this can soft led light source sends also can reduce dazzle, but light surpasses more than 25% through the secondary transmission loss;

2, be installed in led light source on the reflection kernel point of reflector, led light source is towards the bottom of reflector, and light fixture penetrates only all reflects through reflector; Can reduce dazzle like this, the efficient of reflection is also very high, the bad solution but led light source dispels the heat; Too thick with metallic support; Shading, contact-making surface is little, is unfavorable for heat conduction and heat radiation; Do support with heat pipe,, can only solve the heat conduction problem of low-power LED light source owing to use the diameter of heat pipe little, and the expensive of heat pipe;

3, add bead loading face, shine literary composition, frosted, the lens of cloth check can reduce dazzle, but light surpasses more than 20% through the secondary transmission loss.

The utility model content

In view of this, the utility model technical problem to be solved provides a kind of catch light reflection efficiency that has, and is with low cost, simple in structure, can solve the LED light fixture of the glare problem of LED light fixture.

The utility model technical problem to be solved is achieved through following technical scheme:

A kind of LED light fixture; Comprise reflection shield with the led light source that is positioned at reflection shield bottom, be used for radiator that the heat that led light source produces is distributed; Also comprise glare filter; Said glare filter is made up of the support of reflective convex and reflective convex sidewall, and said support is fixed on the front end of reflection shield, and said reflective convex is towards the reflection shield bottom direction and over against led light source.

The surface of said reflective convex is a plating face.

The reflective convex and the support of said glare filter are as a whole.

The utlity model has following beneficial effect:

The luminous direction of the utility model led light source in reflection shield is provided with glare filter; The reflective convex of glare filter can shelter from the light that led light source outwards directly sends towards led light source, and light is sent through the reflection of reflection shield fully; Be that led light source is hidden in glare filter the inside; Thereby eliminated dazzle, protected consumer's eyes to preserve from, reduced light pollution;

The surface of the utility model reflective convex is a plating face, and is high to the reflection efficiency of light;

The reflective convex and the support of the utility model glare filter are as a whole, available injection molding or aluminium alloy compression casting moulding, and integrated design can reduce the volume of product, can reach same effect, can reduce cost again.

Description of drawings

Fig. 1 is the stereogram of the utility model glare filter;

Fig. 2 is the front view of Fig. 1;

Fig. 3 is the side view of Fig. 1;

Fig. 4 is the installation diagram of glare prevention LED light fixture;

Fig. 5 is the whole structure figure of Fig. 4.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is carried out detailed description.

Shown in Fig. 1 ~ 3, glare filter 1 is made up of a reflective convex 11 and the support 12 that is positioned at reflective convex 11 both sides, and reflective convex 11 is the integrated design with support 12, by the aluminium alloy compression casting moulding.The surface of reflective convex 11 is a plating face.

Fig. 4 and Fig. 5 are installation diagram and the whole structure figure that has the glare prevention LED light fixture of above-mentioned glare filter 1; As shown in the figure; This LED light fixture comprises in lampshade 4, the lampshade 4 and is fixed with reflection shield 3, and led light source 2 is positioned at the bottom of reflection shield 3, and lampshade 4 is outer to be fixed with and to be used for radiator 5 that the heat that led light source 2 produces is distributed; The support 12 of glare filter 1 is fixed on the fixing preceding ring 6 of lampshade 4 front ends, and the reflective convex 11 of glare filter 1 is towards reflection shield 3 bottom direction and over against led light source 2.

Because the reflective convex 11 of glare filter 1 is towards led light source 2; Can the light that led light source 2 outwards directly sends be sheltered from; Light is sent through the reflection of reflection shield 3 fully, and promptly led light source 2 is hidden in glare filter 1 the inside, thereby has eliminated dazzle; Protect consumer's eyes to preserve from, reduced light pollution; Because it is the surface of reflective convex 11 is a plating face, therefore high to the reflection efficiency of light.

The size of the diameter of the utility model reflective convex 11 and radian need to mate according to the characteristic of led light source 2, and promptly the size of the diameter of reflective convex 11 and radian need to be provided with according to the power of the led light source of being installed 2.

The above embodiment has only expressed the embodiment of the utility model; It describes comparatively concrete and detailed; But can not therefore be interpreted as restriction to the utility model claim; In every case adopt the technical scheme that form obtained that is equal to replacement or equivalent transformation, all should drop within the protection domain of the utility model.
