Description of the Invention: [Technical Field] The present invention relates to a light guiding mechanism, and more particularly to a uniform light guiding mechanism for an applied product. Electronics [Prior Art] In electronic products, LEDs (light-emitting diodes) are often used to indicate operating conditions or to achieve a specific lighting effect. The light from the LED is transmitted through the - transparent panel to the outside of the electronic product. In order to evenly distribute the light emitted by the LED, a reflector can be added to the rear of the panel and the LED so that the light emitted by the LED is reflected by the reflector and evenly distributed on the panel. However, after the light emitted by the LED is reflected, the light field wheel temple cannot be bent, and thus, some special light-emitting effects such as an annular light body and a polygonal light body cannot be achieved. SUMMARY OF THE INVENTION In order to provide a uniform light guiding mechanism, the light field contour of the light emitted by the coffee can be curved. : 斤: a light guiding mechanism, comprising: a reflecting portion comprising a first-reflecting surface and a curved second reflecting surface opposite to each other,

The reel 11 is mounted on the base 110. A plurality of holes η are formed in the base 110. A fastener (not shown) passes through the hole 111 to fix the base 110 to the electronic device. on. Referring to and referring to Figures 4 and 5, the uniform light guiding mechanism 12 is made of a transparent resin, and the color of the light passing through the uniform light guide 12 can be changed by changing the color of the material. The uniform light guiding mechanism 12 includes a reflecting portion 122 and a light transmitting portion 123. The reflection 4 122 is annular, the outer ring contour is a polygonal body, and the inner ring wheel gallery is a part of the cone. The outer side surface 125 and the inner side surface 127 are coated with a reflective material to form a first reflecting surface and a second reflection opposite to each other. surface. The first reflecting surface 125 is perpendicular to the bottom surface of the reflecting portion 122, and the second reflecting surface 127 is inclined by 45° with respect to the first reflecting surface 125. A plurality of holes 126 are formed in the reflecting portion 122 adjacent to the outer side surface 125. When the uniform light guiding mechanism 12 is sleeved on the rotating wheel u, a fastener (not shown) can be passed through the hole 126 to fix the uniform light guiding mechanism 12 to On the electronic device 10. The reflecting portion 122 also has a plurality of receiving grooves 124 communicating with the inner ring and evenly distributed, and each receiving groove 124 receives an LED 121. The light transmitting portion 123 is connected to the reflecting portion 122 at the inner ring of the reflecting portion 122 and extends upwardly, and has a cross-sectional shape of a circular ring, which conforms to the shape of the second reflecting surface 127. Since the luminous effect that needs to be achieved in the present embodiment is a circular ring, the uniform light guiding mechanism 12 is annular. The uniform light guiding mechanism 12 can also have other shapes depending on actual needs. For example, when it is desired to achieve a curved illuminating effect, the uniform light mechanism 12 may have a curved shape, and correspondingly, the shape of the light transmitting portion and the second reflecting surface 127 are also curved. The shape of the first reflecting surface 125, the angle between the first reflecting surface 125 and the second reflecting surface 127, and the number of ΕΕ2 ΐ2ι can also be adjusted according to actual needs. Referring to FIG. 6, the LED 121 emits light toward the first reflecting surface 125, and the light enters the reflecting portion 122 to reach the first reflecting surface 125. Since the first reflecting surface 125 is polygonal, the light emitted by the plurality of LEDs passes through the first reflecting surface. After being reflected by 125, it is uniformly distributed in the reflecting portion 122. Referring to FIG. 7, after the light is reflected by the first reflecting surface 125, it reaches the second reflection® 127, and the second-reflex ′ causes the light routing level to become vertical and enters the transmitting portion 123. The light is emitted from the transmitting portion 123 to the outside of =.
