Abstract
The utility model provides a plane polarization light-emitting illumination structure of a lamp, which mainly comprises a light source, a reflection plate, a light guide plate, a diffusion plate, a prism plate and a protective film, wherein the reflection plate is positioned at the bottom of the illumination structure; the light guide plate clings to the upper part of the reflection plate; the diffusion plate, the prism plate and the protective film are arranged on the light guide plate in sequence; the light source is parallel to and is over against the light guide plate; and reflection points are spread over the reflection plate. Compared with a traditional lamp, the utility model has the advantages that a point light source or a line light source of the lamp is changed to a surface light source, light rays are softer, and eyes are effectively protected; and the light rays decline towards one side as a whole and are fully guided to a useful side, so the light ray utilization rate is greatly increased, useless light is reduced, the power of the lamp is guaranteed to be reduced under the same illumination intensity, and energy loss is reduced. Thus the illumination structure has a very important significance for energy conservation and emission reduction.
Description
Technical field
The utility model belongs to field of light fittings, relates to a kind of luminous lighting structure of light fixture, relates in particular to a kind of plano-polarized light luminous lighting structure of light fixture.
Background technology
At present, along with the raising of living standards of urban and rural residents level, various light fixtures have been brought into play important function for satisfying the growing life requirement of people.Conventional lamp adopts spot light or line source, because light is concentrated, light directive property is strong, and meeting intense stimulus people's eyes can not be looked at straight, and reading and writing also can cause certain injury to eyes under this type of light fixture for a long time.So people develop flat luminous light structures, change spot light or line source into area source, make light softer, effectively protect eyes.But people's custom is read in light fixture one side generally speaking, and opposite side light then is wasted.Therefore, design a kind of plano-polarized light luminous lighting structure, make that light fixture light general direction is amesiality, fully light is directed to useful direction, makes light utilization significantly improve, reduce unwanted light, guarantee to reduce under the same illumination power of light fixture, reduce energy loss,, be of great significance energy-saving and emission-reduction.
The utility model content
The purpose of this utility model is to provide a kind of plano-polarized light luminous lighting structure of light fixture, make light fixture become area source by spot light or line source, and light is totally amesiality, fully light is directed to useful side, light utilization is significantly improved, reduce unwanted light, guarantee to reduce under the same illumination power of lamp, reduce energy loss.
The technical solution of the utility model is: a kind of plano-polarized light luminous lighting structure of light fixture mainly comprises: light source, reflecting plate, LGP, diffuser plate, prism plate, diaphragm; Reflecting plate is positioned at the bottom, and LGP is close to reflecting plate top, and the LGP top is followed successively by diffuser plate, prism plate and diaphragm, and light source is parallel over against LGP.
Spreading all on the reflecting plate has pip.
Adopt the accessible beneficial effect of the utility model to be: to compare with conventional lamp; the utility model makes light fixture become area source by spot light or line source, and light is softer, effectively protects eyes; and light is totally amesiality; fully light is directed to useful side, light utilization is significantly improved, reduce unwanted light; guarantee to reduce under the same illumination power of lamp; reduce energy loss,, be of great significance energy-saving and emission-reduction.
Description of drawings
Accompanying drawing is the plano-polarized light luminous lighting structural representation of a kind of light fixture of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.As shown in drawings, in the present embodiment, the plano-polarized light luminous lighting structure of light fixture mainly comprises: light source 1, reflecting plate 2, LGP 3, diffuser plate 4, prism plate 5 and diaphragm 6; Spreading all on the reflecting plate 2 has pip 7.Reflecting plate 2 is positioned at plano-polarized light luminous lighting structural base, and LGP 3 is close to reflecting plate 2 tops, and LGP 3 tops are followed successively by diffuser plate 4, prism plate 5 and diaphragm 6, close proximity successively between them.The light of light source 1 emission is from LGP 3 distolateral injecting, because the material of LGP 3 and the density contrast of air layer, light reflects LGP 3 arrival diffuser plates 4 at LGP 3 inner full-reflections up to running into the pip 7 change reflection directions that set; Spread after pass diaphragm 6 amesiality outputs after prism plate 5 refractions at diffuser plate 4.The angle theta of light outbound course and diaphragm 6 vertical lines is 10-30 °.
Compare with existing light fixture, the utility model makes light fixture become area source by spot light or line source, and light is totally amesiality, fully light is directed to useful side, light utilization is significantly improved, reduce not have and use up, guarantee to reduce under the same illumination power of lamp, reduce energy loss, to energy-saving and emission-reduction, be of great significance.
