Abstract: A color adjusting method for a color light-emitting element is provided. Firstly, a first white light beam is produced by red, green and blue light-emitting units collaboratively, and a second white light beam is produced by a white light-emitting unit. Then, a second chromaticity value corresponding to the second white light beam is acquired. Then, the red, green and blue light-emitting units are controlled to produce a third white light beam according to the second chromaticity value, and a first adjusting parameter is acquired. Then, the white light-emitting unit is controlled to produce a fourth white light beam according to a third luminance value corresponding to the third white light beam, and a second adjusting parameter is acquired. Then, a gray level adjustment process is performed according to the first and second adjusting parameters.

CPC classification number: H02M1/088 , H02M3/33569
Abstract: An input system includes a first input device and a second input device. Each of the first input device and the second input device includes a main body, a first connecting port, at least two second connecting ports, a power switching circuit and a control unit. When the first connecting port of the first input device is connected with an external power source, the power switching circuit of the first input device receives a first voltage from the external power source. When one of the second connecting ports of the first input device is connected with one of the second connecting ports of the second input device, the first voltage is converted into a second voltage by the power switching circuit of the first input device and the second voltage is transmitted to the second input device.

Abstract: An input device includes a universal serial bus interface, a white light-emitting diode unit, a red light-emitting diode unit, a green light-emitting diode unit, a blue light-emitting diode unit and a driving part. The driving part receives electricity through the universal serial bus and drives at least one of the white light-emitting diode unit, the red light-emitting diode unit, the green light-emitting diode unit and the blue light-emitting diode unit to emit a light beam. Consequently, the light beam with a higher luminous intensity and a specified color is outputted from the input device.
