1. Technical Field
The disclosure generally relates to keyboards, and particularly to a keyboard having an illuminating device.
2. Description of Related Art
Keyboards are usually an essential peripheral of an electronic device. An additional illuminating apparatus is needed to supply illumination when the keyboard is used in a dark environment. Therefore, what is needed is a keyboard having an illuminating device.
The components of the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments of a keyboard. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views.
Referring to
The base board 30 includes an upper surface 320 defining a rectangular receiving space 310. The circuit board 50 is housed in the receiving space 310. The keypad portion 20 is received in the receiving space 310, covers and is electrically connected to the circuit board 50. A slot 330 is defined in the upper surface 310. The slot 330 is substantially rectangular and surrounds the receiving space 310. The illuminating device 40 is mounted in the slot 330 and is further electrically connected to the circuit board 50. In the embodiment, the illuminating device 40 includes a plurality of illuminating units, such as, LEDs (light-emitting diodes). In other embodiment, the illuminating device 40 is a flexible illuminating strip. The flexible illuminating strip is disposed substantially coplanar with respect to a top surface of the keypad portion 20. The circuit board 50 is further electrically connected to a power supply (not shown). The power supply is configured to supply the illuminating device 40 with power.
The keyboard 10 further includes a switch 60. In the embodiment, the switch 60 is mounted at a side surface of the base board 30. In other embodiments, the position of the switch 60 mounted at other locations on the keyboard 10. The illuminating device 40 is electrically connected to the circuit board 50 via the switch 60. the switch 60 controls power to the illuminating device 40.
In other embodiments, when the keyboard 10 is connected to an external processing system (not shown), for example, a personal computer. Power to the illuminating device 40 can be controlled via software drivers of the external processing system.
Although the present disclosure has been specifically described on the basis of the embodiments thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiments without departing from the scope and spirit of the disclosure.
