Abstract
The utility model discloses a combined type LGP composed of a transparent base plate and a transparent film. A plurality of light guide points are printed on the transparent film which is attached to the backside of the transparent base plate. According to the combined type LGP, the light guide points are printed on the transparent film firstly, then the transparent film printed with the light guide points is combined with the transparent base plate so as to form the LGP, the printing of the light guide points on the transparent film is easier to achieve compared with the prior art in which the light guide points are printed directly on the transparent base plate, the processing difficulty is reduced, the processing yield is improved, even if poor LGP needs to scrap, only the transparent film portion needs to scrap while the transparent base plate portion is in perfect condition, therefore cost can be reduced.
Description
Technical field
The utility model belongs to field of photovoltaic materials, is specifically related to a kind of illumination or display and uses LGP.
Background technology
LGP is the high-tech product that line source is converted into area source.The LGP of prior art is acrylic (PMMA) sheet material that utilizes optical grade, then with having the high reflectivity and the printing ink of extinction not, the acrylic sheet material bottom surface of optical grade with printing on the leaded light point.The light that utilizes optical grade acrylic sheet material to draw to send from lamp is in the stop on optical grade acrylic sheet material surface, and when light was mapped to each leaded light point, reflected light can destroy conditioned reflex by the positive ejaculation of LGP then toward all angles diffusion.Through various densitys, leaded light point not of uniform size, can make the LGP uniformly light-emitting.LGP generally cooperates reflector plate and uses at its positive diffuser plate that cooperates at its back side; In the light reflected back LGP that the purposes of reflector plate is bottom surface of light guide plate is exposed; Be used for improving the service efficiency of light, the purposes of diffuser plate is further to make light softer the light expanding.Structure and principle through above-mentioned prior art LGP can know that the leaded light point on the LGP of prior art is directly to be printed on the bottom surface of LGP, and this technology is very difficult in practical operation, and yield is lower, so cost is high.
The utility model content
In order to overcome above-mentioned defective; The utility model provides a kind of compound LGP, and this compound LGP can be converted into area source with line source, is applicable to fields such as illumination and display; And can reduce manufacture difficulty; Cost is low, helps improving market share, again and simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical matters and adopt is:
A kind of compound LGP has transparency carrier and hyaline membrane, and said hyaline membrane is printed with some leaded light points, and said transparency carrier has two relative surfaces and is respectively front and back, and said hyaline membrane is attached at the back side of said transparency carrier.The utility model is printed in leaded light point on the transparent membrane earlier, and then the transparent membrane that will be printed with leaded light point combines with transparency carrier, thereby forms LGP; Because the leaded light point is to be printed on the transparent membrane, therefore directly be printed on the transparency carrier and will realize more easily than prior art, reduced the processing procedure difficulty; Improved process rate, even and bad scrapping appears, also only need scrap the transparent membrane part; And transparency carrier is partly excellent, therefore can reduce cost.
The utility model for the further technical scheme that solves its technical matters and adopt is:
Said transparency carrier can be acrylic board or glass plate.
Said some leaded light points are printed in said hyaline membrane and are attached on the one side of said transparency carrier, also can be printed on the one side of said hyaline membrane away from said transparency carrier.
The beneficial effect of the utility model is: the compound LGP of the utility model has transparency carrier and hyaline membrane, and hyaline membrane is printed with some leaded light points and is attached at the back side of said transparency carrier, and the utility model is to be printed in leaded light point on the transparent membrane earlier; And then the transparent membrane that will be printed with leaded light point combines with transparency carrier; Thereby the formation LGP because the leaded light point is to be printed on the transparent membrane, therefore directly is printed on the transparency carrier and will realizes more easily than prior art; Reduced the processing procedure difficulty; Improved process rate, even and bad scrapping appears, also only need scrap the transparent membrane part; And transparency carrier is partly excellent, therefore can reduce cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below through the embodiment of specific instantiation explanation the utility model, the personage who is familiar with this skill can be understood the advantage and the effect of the utility model easily by the content that this instructions disclosed.The utility model also can other different mode be implemented, and, under the category that discloses from the utility model that is not contrary to, can give different modifications and change that is.
Embodiment: a kind of compound LGP; Have transparency carrier 1 and hyaline membrane 2; Said hyaline membrane is printed with some leaded light points, and said transparency carrier has two relative surfaces and is respectively front and back, and said hyaline membrane is attached at the back side of said transparency carrier.The utility model is printed in leaded light point on the transparent membrane earlier, and then the transparent membrane that will be printed with leaded light point combines with transparency carrier, thereby forms LGP; Because the leaded light point is to be printed on the transparent membrane, therefore directly be printed on the transparency carrier and will realize more easily than prior art, reduced the processing procedure difficulty; Improved process rate, even and bad scrapping appears, also only need scrap the transparent membrane part; And transparency carrier is partly excellent, therefore can reduce cost.
Said transparency carrier can be acrylic board or glass plate.
Said some leaded light points are printed in said hyaline membrane and are attached on the one side of said transparency carrier, also can be printed on the one side of said hyaline membrane away from said transparency carrier.
The foregoing description is merely illustrative the utility model principle and effect thereof, but not is used to limit the utility model.The rights protection scope of the utility model should be listed like claims.
Claims (5)
1. compound LGP; It is characterized in that: have transparency carrier (1) and hyaline membrane (2); Said hyaline membrane is printed with some leaded light points, and said transparency carrier has two relative surfaces and is respectively front and back, and said hyaline membrane is attached at the back side of said transparency carrier.
2. compound LGP as claimed in claim 1 is characterized in that: said transparency carrier is an acrylic board.
