The light incident surface 21 is for receiving a light source emitted by the matched light source a, and the light is transmitted from the light incident surface 21 after entering the light guide plate 2, that is, inside the light guide plate 2. The reflecting surface 22 is adjacent to the light incident surface 21 and located on one side of the light guide plate 2. In order to increase the light collecting effect of the reflecting surface 22, the present invention can be implemented with a plurality of cross sections on the reflecting surface 22 The light guiding structure 2 21 is formed in a v-shape, and the guiding direction of the light guiding structure 21 is parallel to the light source a. The light-emitting surface 2 3 is adjacent to the light-incident surface 2; [and is opposite to the reflection surface 22, and the light-emitting surface 23 is provided with a plurality of light guides having a cross-section in the shape of a v and perpendicular to the light source a. Structure 2 31 'where the light guiding structure 2 3 1 located in the central region of the light guide plate 2 is in the form of a positive V shape, but the light guiding structures 2 31 which are respectively located in the two side regions of the photoconductive plate 2 are in a non- a v-shaped body, and the two oblique sides are formed into a long oblique bevel ^1 a and a short oblique bevel 2 3!b, and the long oblique bevel 2 3丄a is a sinful guide In the direction of the side edge of the light plate 2, the angle between the long oblique edge 2 31a and the light exit surface 23 of the light guide plate 2 is smaller than the angle θ 2 of the short oblique side 23 1 b and the K surface 2 3 The closer to the side edge of the light guide plate 2, the smaller the angle θ 1 7 1344554 between the long bevel 2 31 a and the light exit surface 2 3 . The light of the light source A enters the inside of the light guide plate 2 from the light incident surface 21, and the light source incident on the reflective surface 22 is reflected by the surface. The direction of the light guiding structure 21 1 on the light emitting surface 23 is perpendicular to the light of the light, and the light guiding structure of the surface of the reflecting surface 22 is directed to the light source. A is parallel to each other, whereby the light source can have a different direction of collecting light when it is obliquely edged by the light guiding structures 2 3 1 and 2 2 k, and in addition, although the light is entering In the case of the light guide plate 2, the light field distribution on the two sides of the light guide plate 2 is shifted toward the two sides. However, since the light guide structure 2 3 i located in the light guide surface 2 on both sides of the light guide plate 2 is formed into one. The long oblique side 2 31 a and the short oblique side 2 31b, and the long oblique side 2 3丨a is disposed in the direction of the side edge of the light guide plate 2, therefore, the light source of the light source and the light guiding surface 2 3 When the long oblique side 2 31a of the 31 is refracted, the light of the refracted light will deviate from the normal line L and make the system guide forward in the forward direction, and at the same time, the closer to the light guide plate 2 by the long oblique edge ^ 3 la The angle between the side angle and the angle of the exit surface 23 is gradually smaller, so that the inclination angle of the long oblique side 2 3 ! 3 of the scale structure 2 3 1 also changes accordingly, so that the step can make the near light guide plate The guiding structure of the two sides is 2 3 1, using the long oblique side 2 3丄a of different inclination angles to make the light source reach the different degree of refraction, and the output source is directed to the positive direction, and the guiding light source 2 is uniform. The degree of improvement, as shown in Figure 6. The effect of the present invention is that the light guide structure 2 31 of the light guide plate 2 is provided with a plurality of 8 344 554 light guide structures 2 31 ', and the light guide structure 2 31 located at the two sides of the light guide plate 2 is a non-positive V shape. And the second oblique side becomes a long oblique side 2 31a and a short oblique side 2 31b, and the closer to the side edge of the light guide plate 2, the long oblique side 2 3 1 a and the light emitting surface 2 3 The angle of the 6» 1 angle is smaller. When the light source is refracted by using the long oblique side 2 31 a to different angles of inclination, the light is refracted
