Abstract
The utility model relates to a light guide module comprising a light guide plate, a light source and an optical glue layer, wherein the light guide plate is provided with a reflection surface which has a plurality of microstructures for reflecting light; the light source is arranged at one side surface of the light guide plate; and the optical glue layer is covered on the reflection surface. On the light guide plate of the light guide module, a concave surface or a convex surface, formed by filling the microstructures by the optical glue layer, is used for weakening light scattering phenomena on the microstructures. Therefore, patterns or characters formed by the arrangement of the microstructures can be observed more clearly by an observer at the vertical direction of the light guide plate.
Description
Technical field
The utility model is about a kind of leaded light module, refers to especially a kind ofly improve LGP in the leaded light module of the penetrance of its vertical direction by the optics glue-line.
Background technology
The employed display screen of many electronic goods is implemented with the leaded light module of configuration LGP.Such LGP is often with printing optical oil film or next in the additional very tiny micro-structural in its surface with the processing mode of local failure light conducting plate structure, right such micro-structural is everlasting on the LGP because process forms the sample attitude of White-opalescent block or vaporific distribution, and significantly reduces the penetrance of light.See also Fig. 1, it is for the part side schematic view of the leaded light module 100 that general electronic goods was equipped with.Leaded light module 100 comprises LGP 110 and reflecting plate 155, and by the light emitting source of light source 150 as leaded light module 100, wherein is full of air between LGP 110 and the reflecting plate 155 and does not have other media.Micro-structural 120_A, 120_B, 120_C, 120_D have been added with above-mentioned processing mode on the LGP 110.Reflecting plate 155 is used for the light that reflection source 150 sends.When light that light source 150 sends arrives micro-structural set on the LGP 110 (micro-structural 120_A for example shown in Figure 1 or 120_B), light can be reflected by micro-structural because refringence between light-passing board 110 and the air is big or reflect, and produces light scattering phenomenon as shown in Figure 1.Yet, many electronic products are on the market arranged at present when using this type of to be provided with the LGP of micro-structural, can painstakingly micro-structural be arranged in literal or pattern on LGP with meaning, to represent the usefulness of specific information, for example be arranged in the trade mark of electronic product and on LGP, show; And the light scattering phenomenon that above-mentioned micro-structural caused, it is smudgy to make that literal that this type of is arranged out on LGP with micro-structural or pattern become.
The utility model content
The utility model discloses a kind of leaded light module, is used for concentrating by the light of micro-structural scattering, to solve the light scattering phenomenon that micro-structural causes in the prior art on LGP.
The utility model discloses a kind of leaded light module, comprise LGP, reflecting plate and light source, this LGP comprises first with a plurality of micro-structurals, this light source is arranged at a side of this LGP, this reflecting plate is in order to reflect the light that this light source sends, this leaded light module also comprises the optics glue-line, and it is arranged between this first of this LGP and this reflecting plate, and the difference of the refractive index of the refractive index of this optics glue-line and this LGP is less than a particular value.
Leaded light module as described, this reflecting plate are arranged at this optics glue-line one side and this optics glue-line between this LGP and this reflecting plate.
Leaded light module as described, these a plurality of micro-structurals are arranged in specific character and/or special symbol.
Leaded light module as described, these a plurality of micro-structurals constitute with depression or protruding mode.
Can be further understood by following description of drawings and specific embodiment detailed description in advantage of the present utility model and spirit.
Description of drawings
Fig. 1 is the part side schematic view of the leaded light module that general electronic goods was equipped with.
Fig. 2 is the part side schematic view according to the disclosed leaded light module of an embodiment of the present utility model.
Fig. 3 and Fig. 4 are for disclosing the schematic top plan view of LGP shown in Figure 2 according to two embodiment of the present utility model.
The specific embodiment
See also Fig. 2, it is the part side schematic view according to the disclosed leaded light module 200 of an embodiment of the present utility model.As shown in Figure 2, leaded light module 200 is except including LGP 110, reflecting plate 115, and beyond the light source 150, fill with optics glue-line 130 in space between LGP 110 and reflecting plate 115, make micro-structural 120_A on first of LGP 110,120_B, 120_C, concave surface that 120_D is caused on LGP 110 or convex surface are covered by optics glue-line 130 and fill and lead up, the practice that wherein optics glue-line 130 is filled between LGP 110 and the reflecting plate 115 comprises the ejaculation typing, spraying etc. generally is used for the procedure for processing of colloidal liquid material, and this optics glue-line 130 is the optical lens gelatin.Light source 150 is arranged at a side of this LGP 110.These a plurality of micro-structurals constitute with depression or protruding mode.
The difference of the refractive index of the refractive index of optics glue-line 130 and LGP 110 needs less than a particular value, make when light that light source 150 sends arrives on the LGP 110 interface between micro-structural 120_A, 120_B, 120_C, 120_D and the optics glue-line 130, can be because the difference of the refractive index of the refractive index of LGP 110 and optics glue-line 130 less than a particular value, can be refracted or reflect hardly because of refractive index differs less.As shown in Figure 2, most light that light source 150 is sent still can arrive reflecting plate 115 after by micro-structural, and the vertical direction that is reflected in LGP 110 of penetration plate 115 obtains uniform light reflection again; Thus, the light scattering phenomenon that produces on micro-structural as shown in Figure 1 will significantly be weakened, and the beholder who makes vertical direction observe LGP 110 can more clearly watch the light by micro-structural 120_A, 120_B, 120_C, 120_D.In a preferred embodiment of the present utility model, the refringence between optics glue-line 130 and the LGP 110 is less than 0.1.
See also Fig. 3 and Fig. 4, it is for disclosing the schematic top plan view of LGP shown in Figure 2 110 according to two embodiment of the present utility model.As shown in Figure 3, a plurality of micro-structurals 120 are arranged in specific character and/or special symbol 160 on LGP 110, pattern as English alphabet A, and because the embodiment of leaded light module 200 shown in Figure 2, the scattering phenomenon that can occur light around those micro-structurals 120_A, 120_B, 120_C, the 120_D hardly, and make that those micro-structurals 120_A, 120_B, 120_C, the 120_D that the beholder watched of the vertical direction that is positioned at LGP 110 are comparatively clear.And in Fig. 4, in order to make LGP 110 produce visual effect comparatively uniformly, those micro-structurals 120_A on the LGP 110,120_B, 120_C, 120_D present uniform distribution, and with identical around those micro-structurals 120_A shown in Figure 3,120_B, 120_C, the 120_D, the phenomenon of light scattering can't occur, and make the beholder of the vertical direction that is positioned at LGP 110 can watch those micro-structurals 120_A, 120_B, 120_C, 120_D comparatively clearly.
The utility model discloses a kind of leaded light module.On the LGP that this leaded light module is comprised, fill up concave surface or the convex surface that micro-structural is caused, be used for weakening the light scattering phenomenon on the micro-structural with optical cement.Thus, the beholder who is positioned at the vertical direction of LGP can watch the formed pattern of layout or the literal of micro-structural more clearly.
The above only is the preferred embodiment of this creation, and the equalization that Fan Yiben creation claim is done changes and modifies, and all should belong to the covering scope of this creation.
