One of the sides is formed with a rough surface that changes the path of the light travel, and a plurality of V-shaped grooves are formed on the outer side surface, so that when the reflective layer coated on the inner side of the curved light guide plate receives light from the light-emitting element, The rough reflective area changes the light path so that the reflected light can be emitted through the area to provide a wide-angle illumination area. In addition, the V-shaped groove is used to reflect the 4 M364187 light to the side of the curved light guide plate. The diffuser increases the angle of reflection of the reflected light to provide a wider illumination area. The second objective of this creation is to maximize the lighting benefits with the smallest light-emitting diode (L E D ) due to the use of curved surfaces to increase the range of illumination. Another purpose of this creation is to use the reflection area to evenly distribute the light of the light-emitting diode (L E D ), thereby improving the illumination. A further object of the present invention is to control the brightness and angle of the light as the density of the reflective area is gradually increased to change the path of the light.

The light guide structure 2 is mainly composed of a curved light guide plate 20 (such as transparent or translucent) and a reflective layer 2 2 (eg, a reflective sheet), wherein a plurality of light-emitting elements 2 M364187 4 (L ED) are provided on the side of the curved light guide 20, and a rough surface of the reflective area 2 for changing the light path is formed on the curved light guide 2 , the concave point or the dot area), and the inner side of the curved piece 3 is covered on the reflection area 20 2 to provide a reflective light source', and the reflective layer 2 2 forms a thin metal reflective layer, thereby illuminating At the same time, the light gradually increases the path along with the reflection area of the curved side of the curved surface, and then controls the brightness and angle of the light. The layer 2 2 enhances the reflectivity of the overall light, thereby improving the illumination to maximize the illumination. Please refer to the fourth and fifth figures for lighting, In the embodiment, the three-dimensional schematic diagram of the diffuser is arranged on the curved surface and the light diagram of the fourth-shaped structure is clearly seen in the figure. The light-emitting element is disposed on the two ends of the curved light guide plate 2 为a as an example 2 4 a When illuminating, the light changes the path of light with the reflection area 2 0 2 a of one side of the curve a, thereby controlling the luminosity, and then increasing the overall rate by the reflection layer 2 2 a, thereby increasing the light and thereby improving the illumination. degree. Furthermore, the curved light guide plate 20 a is covered with the diffusion sheet 2 6 a or the diaphragm 2 8 a. Taking the diffusion sheet 6 6 a as an example, the reflection is completed and refracted to one of the sides via the curved light guide plate 20 a. 0 2 (eg: ί light guide 2 〇 reflective layer 2 2 steam money / money money when the light component light board 2 0 to change the light and then increase the efficiency by reflecting light. This is the schematic diagram of the outer side path of the creation light board 2 4 a, when the density of the light-emitting surface of the light guide plate 2 is gradually increased, and the outer side of the reflection of the angular light is covered with one of the 'after the light, the diffusion sheet 2 6 6 M364187 a , so that the light passes through the diffusion sheet 2 6 a The light irradiation range can be increased, and the transmittance of the curved surface light guide plate 20 a can determine the amount of light to control the brightness and darkness, so that the diffusion range can be increased by using the diffusion sheet 26 6 a, so that the minimum use can be used. The light-emitting element 2 4 a (LED) achieves the maximum illumination benefit, and the reflection area of the inner side surface of the curved light guide plate 20 a can evenly distribute the light of the light-emitting element 24 a, thereby improving the illumination.

It can be clearly seen from the figure that a plurality of V-shaped grooves 204b are formed in the longitudinal or lateral direction on the outer surface of the curved light guide plate 2 Ob, and the curved light guide plate 20b is formed. —Lighting at the end edge • When the component 2 4 b emits light, the light gradually increases with the density of one of the reflective areas 2 0 2 b on the inner surface of the curved light guide plate 20 b to change the path of the light, thereby controlling the brightness and angle of the light. Then, by using the reflective layer 2 2 b to increase the reflectivity of the overall light, the light is increased to enhance the illumination. 'When the reflected light is completed, the curved light guide plate is used. 2 0 b The V-shaped groove on the outer side of the surface 2 0 4 b again reflects to increase the illumination, and the reflected light is incident on the diffusion sheet 2 6 b , and the light can be increased by the diffusion sheet 2 6 b 7 M364187, and the curved surface light guide 2 Q b The luminosity determines the amount of light that can be emitted to control the brightness. 'So that you can use the diffuser 2 6 b to increase the illumination range' so you can use the least amount of light-emitting elements 2 4 b (light-emitting body) to achieve maximum illumination benefits. The reflection area of the inner side surface of the curved light guide plate 20b can evenly distribute the light of the light-emitting element 24b, thereby achieving the improvement of the illumination level, which is only the original creation, and thus is not limited to the present yoke.
