Description
Technical field
The utility model relates to a kind of LGP, especially relates to the LGP that a kind of embedded LED has both leaded light and scattering function.
Background technology
LGP is a kind of important smooth transmitting medium that spot light is changed into planar light source.If make on LGP and embed semiconductor light-emitting-diode (LED), then the LED spot light conducts propagation forward along the optics site of LGP, to obtain luminous even planar light source.Existing LGP major part is to be designed to that size is totally different, the protruding netted particulate (or recessed micropore) of different, the One's name is legion of distance, it will play scattering of light and refraction action, conducting beam divergence, be refracted to planar surface along flat board, thereby make monoblock optics LGP send soft, uniform in-plane light, therefore can show many information (literal, image, symbol, animation etc.) of LCD (LCD).
Notification number be the patent of invention of CN1485658 disclose a kind ofly have double-side, the be used for LCD LGP of (LCD).LGP is respectively equipped with two exiting surfaces, on one side it is provided with a diffusion barrier and a LCD (LCD) composition, is used to show the LCD module of information.It mainly is to be provided with most separation portions in the LGP medium dip, the direction of each separation portion inclination system by the adjacent edge of incidence surface and an exiting surface wherein to another exiting surface extending on one side away from incidence surface, and the parting surface system of the contiguous incidence surface of each separation portion is towards the form of incidence surface protrusion, in order to do make the light that enters by incidence surface can be after the reflection of parting surface and refraction respectively towards an inclined-plane of LGP, i.e. exiting surface refraction, transmit; Also can be by the LGP another side, through diffusion barrier with the light scattering after, be projected to the upper surface LCD MODULE.
Summary of the invention
The purpose of this utility model provides a kind of LGP that has both leaded light and scattering function.
The utility model is a platy structure, and upper surface is the plane, is provided with convex or matrix micro-structural site battle array on upper surface, and lower surface is curved surface or cambered surface, is provided with fine optical scattering dot matrix on lower surface.
Described convex or matrix micro-structural site battle array can be Merlon (PC) convex or matrix micro-structural site battle array or acrylic (PMMA) convex or matrix micro-structural site battle array.
Described fine optical scattering dot matrix, be from tabular structural edge to central authorities from gradually dredging to gradually close distribution.
The thickness of described platy structure can be 1.0～12mm.
Described curved surface preferably cross section is the curved surface (being commonly called as bat shape wing plane) of V-arrangement, and the angle of the curved surface of V-arrangement is preferably 165 °～178 °; The radius of curvature of described cambered surface can be 8～12cm, and the radius of curvature of described cambered surface is preferably 10cm, and the angle that described cambered surface is formed to the both sides of the edge line with the center is preferably 165 °～178 °.
Compare with existing LGP, the utlity model has following outstanding advantage:
Therefore the utility model can make LGP have good optics printing opacity and leaded light performance owing to be provided with convex or matrix micro-structural site battle array on the surface of LGP.Particularly because convex or matrix micro-structural site battle array adopt Merlon (PC) convex or matrix micro-structural site battle array or acrylic (PMMA) convex or matrix micro-structural site battle array, therefore good optics printing opacity and the leaded light performance that can utilize this type of macromolecular material to have makes LGP have better optics printing opacity and leaded light performance.In addition, the LGP lower surface is designed to the organic assembling body of two acute angle right angle wedges splicing, and be provided with at lower surface spread all over the place, intensive fine optical scattering point, from the LGP edge to central authorities from dredging to gradually close distribution.Position of center line is two acute angle triangular prism infalls.From macroscopic view, similar is a plane that has the scattering thin layer composition of vaporific structure.
The utility model also can be used for multiform shape, the plane geometry illumination elegant in appearance of many patterns except that can be used for the LCD display backlight, the LGP that has both leaded light and scattering function of decorate flat luminous panel and decoration plane background light source etc.
