DETAILED DESCRIPTION OF THE INVENTION
The present invention discloses a lighting effect-controllable computer case. Refer to FIG. 1 a diagram schematically showing a lighting effect-controllable computer case according to one embodiment of the present invention. The lighting effect-controllable computer case of the present invention comprises a computer case 10, a lighting controller 12 and at least one LED light strip 18. The computer case 10 contains electrically-connected computer components, including a motherboard 14, a power source 16, hard disc drives (not shown in the drawings), optical disc drives (not shown in the drawings), etc.
The lighting controller 12 is disposed inside or outside the computer case 10, and electrically connected with the motherboard 14. The LED light strips 18 are arranged inside the computer case 10 or disposed on the external surface of the computer case 10. The LED light strips 18 are electrically connected with the lighting controller 12. The LED light strips 18 are mutually connected with connection members 186. Each LED light strip 18 includes a plurality of LEDs 184. The lighting controller 12 sends out at least one control signal. The control signals control the LED light strips 18 to present different lighting effects. For example, the lighting controller 12 controls the LED light strips 18 to flash at different frequencies or light up continuously; the lighting controller 12 controls the LED light strips 18 to light cyclically; the lighting controller 12 controls the LED light strips 18 to emit different colored lights; the lighting controller 12 controls LEDs 184 to light up in an alternate way, i.e. one LED 184 is lighted up with two LEDs 184 beside the lighted up LED 184 are turned off. The control signal will be transmitted from one LED light strip 18 to the next LED light strip 18 through the connection member 186. Further, the control signal can control a single LED 184.
The computer system further comprises a screen electrically connected with the motherboard 14 inside the computer case 10. An application program installed in the computer is used to send out instructions enabling the lighting controller 12 to generate control signals. The user interface 20 of the application program is presented on the screen, and the user uses the user-interface 20 to input instructions to control the lighting effects of the LED light strips 18. The instructions are transmitted to the lighting controller 12 through the motherboard 14. In one embodiment, the application program is installed in a mobile device, such as a mobile phone or a tablet computer. In such a case, the user interface 20 is an operating interface of the application program installed in the mobile device.
Refer to FIG. 2 a diagram schematically showing a lighting controller according to one embodiment of the present invention. The lighting controller 12 has a plurality of sockets, including a power source socket 122, a connection port 124 and at least one light strip socket 126. The power source socket 122 is used to connect with a power source supplying power to the LED light strips 18. The power to light up all the LEDs 184 is supplied by the lighting controller 12. The connection port 124 may be a USB port. The signal cable is electrically connected with the lighting controller 12 and the motherboard 14. The lighting controller 12 receives the instructions, which are input by the user, from the motherboard 14, and converts the instructions into control signals. The light strip sockets 126 are electrically connected with the LED light strips 18 and transmit the control signals to the LED light strip 18. In other words, the control signals are transmitted from the motherboard 14 through the connection port 124 to the lighting controller 12 and then transmitted from the lighting controller 12 through the light strip sockets 126 to the LED light strips 18.
Refer to FIG. 3 a diagram schematically showing the cascade of the LED light strips according to one embodiment of the present invention. Two ends of the LED light strip 18 respectively have connection heads 188. The connection head 188 can be inserted into the connection member 186, whereby the LED light strips 18 are cascaded.
The computer case 10 is normally made of a metallic material. Magnets are disposed on the backs of the LED light strips 18, whereby the LED light strips 18 can be attached to the computer case 10, and whereby the user can easily adjust the positions and connections of the LED light strips 18, or even arrange the LED light strips 18 to form patterns and provide more lighting effects. In one embodiment, adhesive layers, such as double-side adhesive tapes, are disposed on the backs of the LED light strips 18, whereby after the release paper is stripped off from the double-side adhesive tapes, the LED light strips can be stuck to the computer case 10, which is made of an aluminum-based material or a plastic material, and unable to attract magnets.
In one embodiment, a mobile device is used to control the lighting effect-controllable computer case of the present invention, wherein application programs are installed in the computer and the mobile device. The instructions of the mobile device are uploaded to a cloud server; next, the cloud server transmits the instructions to the computer; next, the computer transmits the instructions to the lighting controller through the motherboard; then, the lighting controller sends the control signals to the LED light strips. Therefore, even though the mobile device and the computer respectively belong to different networks, the mobile device can still control the computer to operate the LED light strips as long as both the mobile device and the computer can link to the Internet.
The LED light strip of the present invention has a plurality of LEDs. However, the lighting controller of the present invention can control individual LEDs. The lighting controller can generate a signal to count the LEDs. Suppose that each LED light strip has 6 LEDs and that 3 LED light strips are cascaded. Thus, there are totally 18 LEDs in the cascaded LED light strips. If the user inputs an instruction: lighting up the first one of every group of three LEDs, the 1st, 4th, 7th, 10th, 13th, 16th . . . LEDs are sequentially lighted up in the first cycle, and the other LEDs are turned off. In the second cycle, the 2nd, 5th, 8th, . . . LEDs are sequentially lighted up, and the other LEDs are turned off. The cascaded LED light strips will operate cyclically in the abovementioned way.
The lighting controller of the present invention will send signals to count the LEDs. Suppose that an LED light strip is added to or removed from one end of the existing cascaded LED light strips, the process of lighting up the LEDs will not be restarted from the 1st LED.
In conclusion, the present invention proposes a lighting effect-controllable computer case, wherein at least one LED light strip is disposed in the computer case, and wherein the application program for controlling the lighting mode and lighting effect of the LED light strips is installed in the computer, and wherein the lighting controller is electrically connected with the motherboard of the computer. The user uses the user interface of the application program to input instructions for modifying parameters. According to the instruction, the lighting controller generates a control signal to the LED light strips. Thereby the user may determine the lighting mode according to his bias, including the number and colors of lighted LEDs, flashing simultaneously or flashing sequentially. The LED light strips may be arranged on the surface of the computer case, providing a dazzling effect. Alternatively, the LED light strips are disposed inside the computer case with the light permeating from the heat dissipation holes, presenting an effect of modest luxury. Therefore, the present invention can fully satisfy users in decorating computer cases.
The embodiments described above are only to exemplify the present invention but not to limit the scope of the present invention. Any equivalent modification or variation according to the characteristic or spirit of the present invention is to be also included within the scope of the present invention.
