Referring to Figures 1 and 2, the surface light source module 1 currently used for a liquid crystal display comprises a light guide plate 11 and a linear light source device i 2 . The light guide plate 11 includes a light incident surface m for allowing light to enter, and a light exit surface 112 which is connected to the top edge of the light incident surface 111 and emits light from the light incident surface into the light guide plate 11 outward. . The illuminating light source device 12 is mounted on one side of the light guide plate U in contact with the light incident surface of the light guide plate u, and can emit light during power supply, and includes a printed circuit board 12 having a long strip shape. A plurality of light emitting diode elements 122 are disposed on the printed circuit board - 121 at intervals. Each of the light-emitting diode elements 122 has a body 123, a light-emitting diode wafer 124, and a package material 125. The body 123 includes a bottom wall 126 and a periphery from the far bottom wall 126. An extended peripheral wall 127, an accommodating space 128 defined by the bottom wall 126 and the peripheral wall 127, and a conductive line 129 formed on the bottom wall 126, the LED substrate 124 and the base 123 The conductive line 129 is electrically connected to the bottom J 126 of the base 123 201111705.

The iu enters the light guide plate 11' portion and is difficult to be reflected by the circumference 127 to change the traveling direction. Then, the packaged adhesive material 125 enters the light guide plate 11 from the light entering the light, and enters the light guide plate from the light incident surface m. The light of U travels in the light guide plate U and is guided to change the traveling direction, and finally exits from the light output Φ m to form a surface light field. The current surface light source module i can provide a surface light field, but the linear light field formed by the linear light source device 12 is formed by connecting the light fields formed by the plurality of light emitting diode elements 122 to each other. Therefore, there is a case where the brightness of the adjacent two-point light field is weak, and the surface light field formed by the light emitted from the light-emitting surface 112 of the light guide plate 11 is formed to be interlaced with bright and dark regions. The phenomenon causes the surface light source module to emit light unevenly. Moreover, when the light emitted by the linear light source device 12 enters the light guide plate η through the encapsulating material 125 and the light incident surface of the light guide plate 11, the light incident surface ln of the light guide plate 11 is one. a plane perpendicular to the main traveling direction of the light, such that when a part of the light travels to contact the light incident surface lu, total reflection occurs and cannot enter the light guide plate 11, and the light that enters the light guide plate 也会 also has a part of the light. The traveling direction is parallel to the light exiting surface u2 of the light guide plate U1 201111705 and cannot be emitted outward from the light exiting surface 112, thereby reducing the amount of light emitted by the surface light source group 1 to form a surface light field, and reducing the surface light field. Luminous uniformity. In addition, during the process of reflecting through the peripheral wall (2) of the linear light source device 12, a portion of the light energy is converted into a hot moon by the peripheral wall 12", so that the light source device ι2 is also reduced. The amount of light emitted 'at the same time' is caused by the accumulation of thermal energy in the interior of the linear light source device 12, which causes the light-emitting lifetime of the light-emitting diodes 124 to be shortened, and the amount of light emitted by the light-emitting diode wafers 124 is not Stabilizing and reducing the amount of light entering the light. In addition, when the surface light source module 1 is used as a light source in an electronic product, it is required to occupy a large portion due to the printed circuit board 121 and the base 123. The assembly space will not only reduce the space of electronic components in the electronic products, but also reduce the functionality of the products. It also makes the electronic products: encountering obstacles in the design of light, thin, short and small directions. Therefore, How to reduce the probability that the light emitted by the linear light source device 12 will totally reflect when it penetrates the human light surface U1 of the light guide plate U, and increase the light output amount and the light emission degree of the Γ-type light source module 1 at the same time. Reduce 敎It is still necessary for the academic community to work together with the industry to broaden the space occupied by the luminous lifetime of the surface light source (4) 1 . [Inventive content] Therefore, the object of the present invention is to provide a high brightness and uniform light emission. The surface light source module of the present invention 201111705 Thus, the invention relates to a seed surface type light source module comprising a line type light source device and a light guide plate. The line type light source device can emit light when power is supplied. The light guide plate includes - available a person who enters the light and enters the top surface of the light surface and emits light from the light surface of the person into the light panel, a plurality of microstructure units formed on the light surface, and a receiving groove defined by the light incident surface and disposed for the linear light source, wherein the micro-frames have a plurality of microstructures which are arranged at a distance from each other and allow the light to pass to change the traveling direction. The groove has a first groove portion, and a second groove portion extending integrally downward from the first groove portion perpendicular to the light-emitting surface direction, the cross section of the first light-incident surface is a quarter-circle, and The second groove portion is sagged 1 The cross section of the light-emitting surface direction is a quarter ellipse. The light emitted by the second-line type light source device enters the light guide plate from the light-incident surface, and then changes to the front of the light-emitting surface and passes through the light-emitting surface. Afterwards, the microstructures are emitted outwardly, and the surface light field of the hook is formed together. The effect of the invention is that the light entering the light surface is reduced by the special setting of the shape of the light guide plate into the light guide plate. When the probability of total reflection occurs, the amount of light on the plate is combined with the microstructure formed on the light surface. The knife light is ejected outward through the microstructure, and the light extraction rate of the surface light source module is greatly increased.

Glowing. The inner edge shape of the accommodating groove 24 defined by the human light surface 21 of the light guide plate 2 is designed to include a first groove portion 241 having a cross section of π 曰, w kn 0-1, and the cross section is four points. The second groove portion of the ellipse, for example, allows the light emitted by the linear device 3 to pass through the sealing material 4 and enter the guiding plate 2 from the human light surface 21, on the one hand, the light-incident surface 21 can be avoided. Total reflection occurs for a plane perpendicular to the main traveling direction of the light, increasing the amount of light passing through the light guide plate 2 while reducing the probability that the traveling direction of the light after entering the light guide plate 2 is parallel to the light exit surface 22, and Increasing the light emitted from the light exit surface 22 201111705, the illuminating surface 21 66 surface is also matched by the microstructures 231, and the shape of the front surface 21 is taken away from the human light surface a The male to the sparse distribution makes the majority of the light Μ 231 clarified by the micro-structured surface light mode to form the high-brightness and uniform light-emitting surface light source, the precursor module. The actual test results show that the light-emitting efficiency of the surface light source module of the present invention is 25% higher than that of the conventional surface-cutting well source module, and the light emission is q 1 first. The average hook is between 8% and 4.6%. Furthermore, since the accommodating groove defined by the 94 ^ E .. surface 21 of the light guide plate 2 is connected to the π long groove, the encapsulating film J is filled in the accommodating groove. In the case of 24, the light-emitting diode chips 32 ^ are smashed out of the sealing material 4, and the packaged F-curable material can be formed into a continuous linear illuminator - When the light exiting from the light-emitting surface 22 6 of the V-plate 2 is outwardly emitted, a uniform knife is formed, and no bright or dark regions are formed alternately. In addition, the seat plate 31 of the linear light source device 3 is made of a flexible material layer 311, and is self-oxidized from the base layer 311 to form the thick: (4) insulating layer 312' and on the insulating layer 312. Forming the conductive lines 313 of the same thickness to form a strip-like state, the line type source can be cleaved, and the volume of the line is greatly reduced. Thus, the liquid crystal display having the surface light source module 4 of the present invention has a light source. A larger space can integrate more electronic components and increase its work (4)' or contribute to the thin design of the liquid crystal display, especially since the base layer 311 of the seat plate 3i is made of a material that can be changed. The linear light source device 3 can also be flexed, so that the surface light source module of the present invention can be applied to the currently developed flexible liquid crystal display as a backlight source to greatly increase the flexibility and application of the surface light source module. 201111705 Scope.

The diode chip 32 can directly derive the heat generated by the light when directly contacting the seat plate 31, thereby prolonging the service life of the linear light source device 3, and increasing the stability and uniformity of the light emission of the linear light source device 3. degree. The actual test results show that the linear light source device 3 of the surface light source module of the present invention has a thermal resistance lower than that of the conventional linear light source device having a housing of 290 K/W. It should be particularly noted here that 'because the base of the seat plate 31 is ------/ 丄丄, the constituent material must be flexible and electrically conductive, and can simply be passed through the base layer 311. The self-oxidation forms the insulating layer 312 upward, and therefore, under the consideration of the above-mentioned article name, the base layer 311 may also be composed of other oxides such as oxygen chopping (Si〇2) and nitriding (Si3N4). $, and the insulating layer 3 12 is formed on the base layer 3 11 by the (4) technology sinking. In summary, the light-emitting diode light source module of the present invention mainly designs the inner edge shape of the accommodating groove 24 defined by the light-incident surface 21 of the _ 2 2 into a quarter circle of a section, 24 And the cross-section is a quarter-two groove portion 242, so that the core 1 of the linear light source device 3 is formed when passing through the package rubber 4 - continuous linear light-emitting region is reduced =:: = = device 3 The emitted light avoids the A reflection when the surface 21 enters the light guide plate 2, and reduces the probability of the light entering the guide plate 2 =: 22 parallel, the same door, the first face is also wrong by the micro The structure 231 is arranged to be densely and evenly distributed along the direction of the 11 201111705 away from the light incident surface 21, so that most of the light can be diffused outwardly by the microstructures 231, thereby making the surface of the present invention. The light source module has a high light output and uniformity of illumination. In addition, the shape of the planar light source module of the present invention can be reduced by the sheet-like design of the seat plate 31, thereby reducing the space occupied by the electronic product. At the same time, because the linear light source device 3 is flexible, the surface light source module of the present invention can be It is used as a backlight for a flexible liquid crystal display, and it is indeed improved that the conventional surface light source module is easy to totally reflect when light enters the light guide plate to reduce the amount of light entering the light guide plate, thereby reducing the amount of light emitted from the light exit surface. Since some of the light energy becomes thermal energy accumulation, the service life of the light-emitting diode wafer is reduced, and the volume is large, which requires a large space, so that the object of the present invention can be achieved. However, the above is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change of the patent application and the description of the invention according to the present invention is Modifications are still within the scope of the invention.
