摘要： A waterproof keyboard comprises: keys, an elastic rubber layer, a circuit board layer, a bottom board, and a sealing layer. The keys are mounted on the bottom board on which a plurality of apertures are disposed, and the sealing layer is disposed under the bottom surface of the bottom board. Corresponding to the apertures on the bottom board, respective adhesives are formed on the sealing layer so as to firmly adhere the sealing layer to the bottom surface of the bottom board.

摘要： An energy-saving light-emitting module is provided, comprising: a light guide plate having a light-incident surface, a bottom surface intersecting the light-incident surface and a light-emitting surface opposite the bottom surface, wherein a plurality of recesses are provided at the bottom surface; a light source placed at one side of the light-incident surface of the light guide plate; and a reflective plate placed at the bottom of the light guide plate for reflecting light rays from the light source into the light guide plate. The light rays emitted by the light source reach the arc surface of each recess at the bottom side of the light guide plate, and the light rays are then reflected to the light-emitting surface. Meanwhile, during the light-emitting process, light rays are concentrated at the arc surface of each recess. The concentration of light rays increases overall luminance produced by the module, and thus, energy is saved effectively.
