Abstract
The utility model provides an LED flat plate light source which effectively prevents a reflective layer from generating wrinkles. A transmitting plate comprises a diffusion layer, a light guide layer and the reflective layer. The diffusion layer fixedly adheres to the opposite side of the light guide layer, the transmitting plate further comprises a protective layer, a clamping space adaptive with the reflective layer is positioned between the protective layer and the light guide layer, and the reflective layer is arranged in the clamping space between the protective layer and the light guide layer in a dissociated mode. The LED flat plate light source has the advantages that the reflective layer is dissociated by arranging the protective layer, the problem that the wrinkles are generated in the reflective layer under the extreme temperature is effectively solved, and the LED flat plate light source is simple and reliable in structure, convenient to dismantle and install, good in universality and low in processing cost.
Description
Technical field
The utility model relates to LED lighting technical field, is specifically related to a kind of LED flat-plate light source.
Background technology
Existing flat-plate light source is to comprise LED light source and light-passing board, light-passing board comprises diffusion layer, optical waveguide layer and reflector layer, and side laminating is fixing in opposite directions for diffusion layer and optical waveguide layer, and LED lamp is arranged on optical waveguide layer side, this technology is used and there is no what problem under normal temperature condition, but because layers of material characteristic is inconsistent, shrinkage factor difference, because reflector layer is adhesively fixed conventionally, in the time that temperature changes, easily make reflector layer produce fold, cause light illumination inhomogeneous, light distributes can not meet design requirement.
Summary of the invention
The problems referred to above that the utility model exists for prior art, provide a kind of and effectively prevent that reflector layer from producing the LED flat-plate light source of fold.
Goal of the invention of the present utility model realizes by following scheme: LED flat-plate light source; comprise LED light source and light-passing board; light-passing board comprises diffusion layer, optical waveguide layer and reflector layer; side laminating is fixing in opposite directions for diffusion layer and optical waveguide layer; light-passing board also includes a protective layer; between protective layer and optical waveguide layer, have and the sandwiched space of reflector layer adaptation, in the free sandwiched space being arranged between protective layer and optical waveguide layer of reflector layer.
Further, described protective layer and optical waveguide layer dorsad the opposite side edge bonding of diffusion layer are fixed, and protective layer and optical waveguide layer bond edge institute region form the sandwiched space with reflector layer thickness and area adaptation.
Further, described protective layer, diffusion layer consistent size, reflector layer size is less than protective layer bonded areas inner edge.
Further, described diffusion layer, optical waveguide layer, reflector layer and the protective layer setting of fitting successively.
Further, described diffusion layer, optical waveguide layer, reflector layer and protective layer cross section are all rectangular.
Further, described diffusion layer, optical waveguide layer, reflector layer and protective layer outer rim are coated with waterproof grommet.
Further, described diffusion layer, optical waveguide layer, reflector layer and protective layer edge are surrounded by same waterproof grommet, the waterproof grommet degree of depth and diffusion layer, optical waveguide layer, reflector layer and protective layer combination thickness adaptation.
Further, described protective layer material is acrylic material.
As another preferred version of protective layer shape, described protective layer material is metal or plastics or timber.
The beneficial effects of the utility model are: make reflector layer free by protective layer is set, effectively prevent that under extreme temperature, reflector layer produces fold; Simple and reliable for structure, easy accessibility; Versatility is good, and processing cost is low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model layer structure schematic diagram.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail:
Shown in accompanying drawing 1 and Fig. 2; LED flat-plate light source of the present utility model; comprise LED light source (not shown) and light-passing board 1; light-passing board 1 comprises diffusion layer 1A, optical waveguide layer 1B and reflector layer 1C; side laminating is fixing in opposite directions for diffusion layer 1A and optical waveguide layer 1B; light-passing board also includes a protective layer 1D, has and the sandwiched space of reflector layer 1C adaptation, in the free sandwiched space being arranged between protective layer 1D and optical waveguide layer 1B of reflector layer 1C between protective layer 1D and optical waveguide layer 1B.
For ease of processing, protective layer 1D and optical waveguide layer 1B dorsad the opposite side edge bonding of diffusion layer fix, and protective layer 1D and optical waveguide layer 1B bond edge institute region form the sandwiched space with reflector layer 1C thickness and area adaptation.The tubular convex edge of putting into for reflector layer can certainly be set on protective layer or optical waveguide layer.
Protective layer 1D, diffusion layer 1A consistent size, reflector layer 1C size is less than protective layer bonded areas inner edge.
In the present embodiment, diffusion layer 1A, optical waveguide layer 1B, reflector layer 1C and protective layer 1D cross section are all rectangular.
For improving waterproof effect, diffusion layer 1A, optical waveguide layer 1B, reflector layer 1C and protective layer 1D outer rim are coated with waterproof grommet 2.
Protective layer 1D material of the present utility model can be also metal or plastics or timber.
Although the utility model illustrates and describes by reference to preferred embodiment, but those of ordinary skill in the art should understand, can be not limited to the description of the present embodiment, in the scope of claims, can make the various variations in form and details.
