Abstract
A luminous keyboard includes plural key structures, a switch circuit board, a supporting plate, a backlight module and plural ring-shaped structures. The switch circuit board is located under the keycaps of the key structures. The supporting plate is located under the switch circuit board and connected with the key structures. The backlight module is located under the supporting plate. The backlight module generates a light beam. The plural ring-shaped structure are disposed on the switch circuit board and arranged around the corresponding key structures. When the light beam is reflected by the key structures, the light beam is received by the plural ring-shaped structure. Due to the material properties of the ring-shaped structures, the periphery regions of the keycaps generate a uniform luminous effect.
Claims10
A luminous keyboard, comprising:
- at least one key structure exposed outside the luminous keyboard;
- a switch circuit board located under the at least one key structure, wherein when the switch circuit board is triggered by the at least one key structure, a corresponding key signal is generated, wherein the switch circuit board comprises at least one circuit board opening;
- a supporting plate located under the switch circuit board and connected with the at least one key structure, wherein the supporting plate comprises at least one supporting plate opening corresponding to the at least one circuit board opening;
- a backlight module located under the supporting plate, and generating a light beam and projecting the light beam to the at least one key structure through the at least one supporting plate opening and the at least one circuit board opening;
- and
- at least one ring-shaped structure corresponding to the at least one key structure, wherein the at least one ring-shaped structure comprises a fluorescent material of a light diffusion material, wherein the at least one ring-shaped structure is disposed on the switch circuit board and arranged around the corresponding key structure at a periphery region of the keycap, wherein when the light beam is reflected by the at least one key structure, the reflected light beam is received by the at least one ring-shaped structure, so that a luminous effect is generated at the periphery region.
