  • Patent number: 9976879
    Abstract: A color wheel rotation speed detecting module is disclosed and includes a color wheel, a motor, a rotation speed detector and a processor. The color wheel includes a first segment and at least one second segment. The motor drives the color wheel to rotate. The rotation speed detector includes an emitter and a receiver. The emitter outputs a light signal to the first segment or the second segment of the color wheel when the color wheel is rotated. When the receiver receives the light signal reflected from the second segment, the receiver outputs a detecting signal correspondingly. When the light signal passes through the first segment and the receiver fails to receive the light signal, the receiver interrupts the output of the detecting signal. The processor receives the detecting signal from the receiver, and obtains the rotating speed of the color wheel according to the detecting signal varied with time.

  • Publication number: 20150059358
    Abstract: A controlling method for a thermoelectric cooling device is provided. The thermoelectric cooling device has a cold side and a hot side. After the thermoelectric cooling device is enabled, a temperature of the cold side and an ambient temperature around the thermoelectric cooling device are acquired. By judging whether the ambient temperature is higher than or equal to a preset reference temperature, an initial value of a duty cycle corresponding to an electric energy to be received by the thermoelectric cooling device is set. Then, a judging step is performed to judge whether the temperature of the cold side is higher than or equal to the ambient temperature. If the judging condition is satisfied, the duty cycle is increased by a specified percentage. If the judging condition is not satisfied and the duty cycle is higher than 0%, the duty cycle is decreased by the specified percentage.
