Abstract
The utility model discloses a light guide component for a side-incidence lighting device. The light guide component comprises a photic layer (4), an intensifying layer (5) arranged at one side of the photic layer (4) and a reflecting layer (6) arranged at the other side of the photic layer (4), wherein the lateral side of the photic layer (4) is a light incidence side and the surface of the intensifying layer (5) is a light emergence side. The surface of the reflecting layer (6) presents a wavy reflection structure, and is provided with at least one total-reflection arc structure. The light guide component is capable of completely evenly emitting light, avoiding the phenomena such as glare or shadows and the like, and improving lighting effect.
Description
Technical field
The utility model relates to a kind of leaded light component, is specifically related to a kind of leaded light component that is used for side incident LED lighting device.
Background technology
Light emitting diode relies on its excellent performance just progressively to move towards household and commercial lighting, uses very extensive.There are problems such as brightness is little in single light emitting diode in the application of illumination.The LED integrated lamp tube then can overcome the problem of luminance shortage, so the LED integrated lamp tube also more and more is welcomed by the general public.
The LED integrated lamp tube of prior art comprises housing and LED integrated chip circuit block, LED integrated chip circuit block is by printed circuit board (PCB) and a plurality of light emitting diodes provided thereon, LED integrated chip circuit block is located in the housing, described housing is made up of base and transparency cover, LED integrated chip circuit block is located at base and transparency cover cooperates in the cavity that forms, and light emitting diode is towards transparency cover.
The LED integrated lamp tube of this kind structure because its light is directly by the hyaline test outgoing, can cause light comparatively dazzling, and the formed multi beam light of a plurality of light emitting diode can cause inhomogeneously, shadow occurs, influences illuminating effect.Yet the lighting device of side incident can solve the problem that prior art exists, and still, does not also propose a kind of light transformational structure that can be used for the side incident light source in the prior art.
Summary of the invention
At the prior art shortcoming, the purpose of this utility model provides a kind of leaded light component that is used for side incident illumination device that the side incident light is converted to vertical evenly ejaculation light and can effectively avoids occurring dazzle or shadow.
For achieving the above object, the technical solution of the utility model is: a kind of leaded light component that is used for side incident illumination device, comprise photic zone, be located at the lustre adding layer of photic zone one side and be located at the reflecting layer of photic zone another side, wherein euphotic side is an incidence surface, and the surface of lustre adding layer is an exiting surface.Side incident light through the leaded light component conversion can effectively solve the uneven phenomenon of light, avoids occurring dazzle or shadow phenomenon.
This surface, reflecting layer is wavy catoptric arrangement, and it has at least one total reflection globoidal structure.
This lustre adding layer surface has a plurality of structures that are recessed structure, male structure or its combination of periodically arranging; Each cycle, width recessed or male structure was between 0.2～4mm; This height recessed or male structure is between 0.1～2mm.
This reflecting layer is the zigzag reflection structure layer, and it has at least one total reflection serrated face structure.
For easy to assembly and reduction complex manufacturing degree, this photic zone, lustre adding layer and reflecting layer can be integrated formed structure; According to the specific design shape of lighting device, but this leaded light component integral body flexible design into strips, shape such as long flat board or plectane.
In order to strengthen the reflecting effect in wavy reflecting layer, the surface in this reflecting layer also is coated with reflectance coating.
Compared with prior art, the utlity model has following advantage:
The utility model can effectively evenly penetrate LED light by side incident light and leaded light component, avoids occurring phenomenons such as dazzle or shadow, effectively improves illuminating effect.
Description of drawings
Fig. 1 is the perspective view of leaded light component of the present utility model;
Fig. 2 is the side schematic view of leaded light component.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in detail.
As shown in Figures 1 and 2, the utility model discloses a kind of leaded light component that is used for side incident illumination device, be particularly useful for the LED integrated lamp tube of side incident, comprise photic zone 4, be located at the lustre adding layer 5 of photic zone 4 one side and be located at the reflecting layer 6 of photic zone 5 another sides, wherein the side of photic zone 4 is an incidence surface, and the surface of lustre adding layer 5 is an exiting surface.Side incident light through the leaded light component conversion can effectively solve the uneven phenomenon of light, avoids occurring dazzle or shadow phenomenon.
These 6 surfaces, reflecting layer are wavy catoptric arrangement, and it has at least one total reflection globoidal structure.In the present embodiment, the quantity of this total reflection globoidal structure is one or three.During this reflecting layer 6 of light directive, under the effect of its total reflection globoidal structure, a large amount of light all can be back to photic zone 4.
These lustre adding layer 5 surfaces have a plurality of structures 7 that are recessed structure, male structure or its combination of periodically arranging; Each cycle, width recessed or male structure 7 was between 0.2～4mm; This height recessed or male structure 7 is between 0.1～2mm.During light process lustre adding layer 5, be the refraction and the diffraction of the recessed/male structure 7 of periodically arranging, light can evenly can come out from lustre adding layer 5 surface emitting.
In addition, this reflecting layer 6 can also be the zigzag reflection structure layer, and it has at least one total reflection serrated face structure.
For easy to assembly and reduction complex manufacturing degree, this photic zone 4, lustre adding layer 5 and reflecting layer 6 can be integrated formed structure; According to the specific design shape of lighting device, but this leaded light component integral body flexible design into strips, shape such as long flat board or plectane.
In order to strengthen the reflecting effect in reflecting layer 6, the surface in this reflecting layer 6 also is coated with reflectance coating 8.
