SUMMARY OF THE INVENTION The present invention relates to a structure of a light guide plate homogenizing light source. The light guide plate of the present invention is made of a good light transmissive material, having a light surface, a reflective surface, and a first surface. The red light guides the light source from the light guide body (four) to the outside, and the reflective surface reflects the light source that is shot here, changes the direction of the light source, and then enters the light relationship in front of the light, and accepts the configured light source. And the light source is guided inside the light guide. The main object of the present invention is to enable the light source of the output to achieve a uniform performance after the light guide of the guide side of the present invention, so as to facilitate the subsequent supply of the liquid source to the display of the solar panel; 2 'The output of the (4) county plate The number of the number of the shirts is (4), the medium is densely covered with the light surface, and the scales are folded or convex. The density of the setting can be the same, or the distance is the source of the light. The distance is different, so the distance from the light surface/light source is more than the touch point, so the bribe is set smaller, that is, the number of silk dots is 1 eve, and the distance from the human brain/Wei Yue In the near future, the stronger the shape of the silk is, the more dense the Ό is, the more the number of light scattering dots i is. Or the size of the light scattering dot is made, or the size is divided into If the size is not the size, the smaller the distance is from the light source/3⁄4 source, and the smaller the distance is from the light surface/light source, the lighter the light source is. When the V-shaped groove is difficult to emit light, the light source can be diffused at the same time, and can be matched with different levels according to different light intensity levels. The light scattering _ is used to optimally cooperate with the light scattering dot. Another object of the present invention is that the reflecting surface of the light guiding plate of the present invention is a roughened matte surface, and the reflecting surface is further provided with a dense cloth. Light scattering dots, which may also be concave or protruded from the surface of the light-emitting surface, and the density of the arrangement may be the same or the distance from the light surface/light source. In some cases, the farther it is from the light surface/light source, the weaker the light intensity is, so the density of the setting is smaller, that is, the smaller the number of light scattering dots, and the distance into the light surface // The closer the light source is, the stronger the light intensity is, the more it is set, the more the number of silk dots, or the size of the light scattering dots is the same, or the size is Divided into different sizes, the smaller the size is, the farther it is from the light surface/light source, and the larger the size is, the closer it is to the light surface/light source. When the light source is reflected on the reflecting surface, the light source can be diffused while being reflected, and the light is scattered. The setting of the dot makes the light source increase its diffusion effect, especially the light scattering dot of different density or size can be matched according to different light intensity, so that the light source and the light (3) 5541 scattering dot are optimally matched. -... To enable your review committee to further understand the structure of the case, the application of technical means, and the effectiveness of its production, as explained in the following figure; the present invention is related to the structure of a light guide plate homogenizing light source, first, please refer to Figure 2 As shown, the light guide plate 2 of the present invention has a light-emitting surface 21, a reflecting surface 2 corresponding to the light-emitting surface 21, and an entrance light connected to at least one side of the light-emitting surface 2i and the reflecting surface 2 2 . The surface 2 is used to guide the light source away from the body of the light guide plate 2, wherein there are a large number of V-shaped grooves 2 ii, and the surface thereof is further provided with a dense light scattering dot 212 ' The light scattering dots 212 may be concave or convex from the surface of the light-emitting surface 21 and the density of the light-emitting dots 212 may be the same, or may be according to the distance from the light surface 2 3 / the light source A. No, make it 2 2 / light from the human face The farther A is, the weaker the light intensity is, the smaller the density of the setting is (the more the quantity is), and the closer the light source is to the light surface 2 3 / the light source A is closer, and the light intensity is stronger, the setting of the service is The larger (the greater the number); the size of the light scattering dot 2丄2 can also be single-size, or the size of the size is different, so that the farther from the light surface 2 3 / light source A The smaller the size is, the larger the size becomes when it is closer to the human light surface 2 3 / the light source A.

The stronger the light intensity, the greater the density of the setting (the more the number of miles).

Therefore, as shown in FIG. 3, the light source emitted by the light source A will enter the light guide plate 2 by the human light surface 21, and the system transmits the light source to the inside of the light guide plate 2 through the human light surface 2, when When the light source is to be separated from the light-emitting surface 2 i, the light source is concentrated by the V-shaped groove 211 of the light-emitting surface 21 to increase the light-emitting brightness and light, and the light is scattered by the arrangement of the light-scattering dots 2 1 2 Transmission of the light scattering dot 2 1 2 causes the light source to diffuse (four) diffuse, making it a more uniform source of light, and enhancing the fine effect. At the same time, according to the distance between the human surface 2 3 / the light source a, when it is farther than the light-emitting surface 2 3 / light source position, the light source energy may be weaker, and the closer to When entering the light surface 2 3 / the position of the light source A, the stronger the energy may be, so the farther away from the light source A, the smaller the density of the silk scattering _ 2丨2 is. (the smaller the number), and vice versa, the closer the light source is to the light source 2 3/light source A, the light scattering dot 2 丄 2 1355541

Or as shown in FIG. 4, the smaller the size of the light-scattering dot 212 is, the closer the light source A is, the closer the light-incident surface 2 3 / the light source A is, the closer the light-scattering dot 2 i is. The larger the size of 2%, the better the fit can be achieved when the light-emitting surface 21 has different light intensity due to different positions. As shown in FIG. 5, when the light source is incident on the reflecting surface 22 of the light guide plate 2, the surface of the light-reflecting surface 22 is a rough surface, and the light source is reflected by the light source. The light source can be diffused to achieve the effect of homogenizing the light source. At this time, the reflecting surface 2 2 is densely covered with a light scattering dot 2 21 ' by the arrangement of the light scattering dots 2 2 将 to increase the light source when it is reflected. Light diffusion effect; when the distance from the light entrance surface 2 3 / the light source A is farther and the light intensity is weaker, the density of the light scattering dot 2 2 is smaller (the smaller the number), and vice versa, the distance into the light surface 2 3/ The closer the light source A is, the stronger the light intensity is, the higher the density of the light scattering dot 2 2 1 is (the greater the number), so that the light falls on different positions of the reflecting surface _ 2 2 and has different light intensity. In this case, the light scattering dots 21 of different densities (numbers) are matched to form a better application. Or as shown in Fig. 6, the farther the spot is 2 1 2 from the light source 2 3 / the light source A, and the closer the light entrance point is to the light source 2 3 / the light source A The larger the size of 2丄2, so that it can also be a better fit when the reflecting surface 22 has different light intensity due to different positions.
