In addition to the above aspects, the shape and number of the first recessed/trapped portions 4-0, 43 and the second recessed portions 41, 42, 44, 45 can be changed correspondingly according to actual design requirements. [0016] In the present invention, the light-emitting portion 3 can be mixed and disposed in different manners of the above-described accommodating grooves 32a, 32b, 32c, and 32d. For example, FIG. 7 is a schematic view showing the light source of the light-emitting keyboard of the present invention being conducted in the light guiding portion, wherein the edge region of the light-emitting portion 30 is in the form of using the receiving groove 32a as shown in FIG. 3; The intermediate portion is a type in which the accommodating grooves 32a and 32c as shown in Fig. 3 and Fig. 5 can be mixed. As shown in FIG. 7 , the 099120367 form number A0101 page 8 / 19 pages 0992035988-0 201201235 The light source will mostly face the first recesses 40 , 43 and the second recesses 41 , 42 . The concave direction is conducted, so that the longitudinal and lateral transmission of the region where the perforation 31 is not provided in the light-emitting portion 30 is performed, thereby causing the keycap 211 to generate illumination brightness. [0018] [0021] [0022] In summary, the illuminated keyboard of the present invention mainly provides the first recessed portion and the second recessed portion in the receiving slot. Using the refraction generated by the light source through the first curved surface and the second curved surface, the light source can be transmitted toward the concave direction of the first concave portion and the second concave portion, and the light source can be used more efficiently. . Therefore, the number of the light-emitting elements used in the illuminated keyboard of the present invention can be greatly reduced, so that the key caps have uniform illumination brightness, so that the manufacturing cost of the illuminated keyboard can be reduced. Therefore, the present invention is extremely progressive and conforms to the requirements of the invention patent application, and the application is filed according to law, and the prayer bureau will grant the patent as soon as possible. The present invention has been described in detail above, but the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the scope of the invention. That is, equalization and modification according to the scope of the present application should remain within the scope of the patent of the present invention.
