The invention can make the light obtain good reflection and/or reflection effect when projecting to the light guide column, and fully utilize the light to improve the brightness of the button. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described in more detail below with reference to the drawings and the reference numerals, which can be implemented by those skilled in the art after having studied this specification. As shown in the first and second figures, an embodiment of the present invention includes at least one button module 1 and at least one backlight module 2, wherein the button module 1 has a bottom plate 11 and a bottom plate 11 A plurality of light guide columns 12 are disposed below, and a button 13 is disposed on the bottom plate 11, and an elastic body 4 is disposed between the button 13 and the bottom plate 11. The elastic body 14 is provided with a first conductive portion 15, and the bottom plate 11 is provided with a circuit board 丨6. The circuit board 16 is provided with a second conductive portion I" corresponding to the position of the first conductive portion 15, and when the button a is pressed, the elastic body 14 can be simultaneously deformed, so that the first conductive portion 15 and the second conductive portion 161 are electrically connected. contact. ‘201030788 The bottom plate 11 and the light guide column 12 can be integrally molded from the same material, or can be made of different materials and then connected. Based on the consideration of the illuminating effect of the button 13, the bottom plate 11 is made of a permeable material that allows light to pass through, and therefore, the guide 12 that is formed in the bottom plate U is also the same permeable material. 'The light column 12 may have different degrees of light transmittance and refractive index due to the difference in materials used.' When the light transmittance of the light guide column 12 is low or the refractive index is high, in order to obtain an effect of increasing the brightness of the button, The light-reflecting rate of the light-guiding column is increased by bonding the ❿-layer light-reflecting substance 17' on the surface of the light-transmitting column 12 with low light transmittance; for example, the light-reflecting substance 17 can be disposed on the light guiding column 12 facing the light as shown in FIG. The surface of the reflective material may be permeable or opaque. When the reflective (four) is permeable, some of the light may be reflected, and another part of the light may penetrate the reflective material and enter the light guide column 12. Refraction; when the anti-news f is impermeable, the light is only reflected by the reflective material. Referring to the figure, the reflective material f 17 can also be disposed on the other surface of the light guiding column 12 with a high light transmittance or a low refractive index with respect to the light, whereby the light is refracted by the light guiding rod 12. When and/or reflecting, the light that some of the counties need to wear through the light guide column 12 can be reflected by the reflective material 17 to the button module to achieve the effect of improving the brightness. The fine view shows that the light guiding column 12 can be replaced by the reflecting column 12A, and the reflecting column m can be made of a material having reflective properties by using a material having a reflective light property, or can be made of a material without reflecting light properties. A reflective substance 17 is further disposed on the surface of the cylinder. 6 201030788 In addition to the reflective effect of the reflective material 17 by the material properties of the reflective material itself, it is also possible to combine the color with the surface of the cylinder to form a reflective column by utilizing the characteristic of the reflected light; for example, the light color has a dark color relative to the dark color. The preferred retroreflective properties are such that a white, gold, silver, or the like pigment can be bonded to the surface of the cylinder to achieve a better retroreflective effect. The backlight module 2 is disposed under the button module 1. The backlight module 2 includes a light guide plate 21 and a light source 23 disposed on a side of the light guide plate. The light source is in the preferred embodiment of the present invention. A light-emitting diode (LED) is used.

The combination of the button module 1 and the backlight module 2 is such that the light guide column 12 or the reflection column 12A combined with the button module J passes through the through hole 22 of the light guide plate 21, and then the light guide plate 杈 12 or the reflection column 12A The end portion is formed into an enlarged head portion 121 to prevent the light guide column 12 or the reflection column 12A from being separated from the light guide plate 21, thereby achieving the purpose of connecting and fixing the button module 1 and the backlight module 2. With the foregoing structure of the present invention, after the light generated by the light source 23 enters the light guide plate 21, part of the light is reflected and/or refracted through the optical structure 24 through the bottom plate U and the button 13, so that the button 13 generates a light-emitting effect; After being projected onto the light guide 12 or the reflective column 12A, the light guide bar 12 refracts and reflects the light from the button U, so that the brightness of the button 13 is improved. Referring to the fourth figure, replacing the light guide column with the reflection column 7 201030788 12A, the projection light is projected onto the reflection column 12 (4). The light can be reflected from the button by the reflection material π or the reflection column m itself, and the brightness of the button can be improved. effect.
