    Abstract: An indoor automatic dimming system includes a lamp control module in connection with a controlled lamp, an optical sensor and a mobile device. The optical sensor senses indoor and outdoor luminance and transmits a piece of sensing data to the lamp control module. The mobile device performs a manual mode and an automatic mode. When the manual mode is performed, the lamp control module drives the controlled lamp according to the piece of sensing data and a control signal transmitted from the mobile device. When the automatic mode is performed, the lamp control module receives a configuration parameter transmitted from the mobile device and automatically adjusts luminance of the controlled lamp according to the piece of sensing data and the configuration parameter. Accordingly, the indoor automatic dimming system can instantly sense indoor/outdoor luminance to maintain a balanced luminance indoors and provide operational convenience.

  • Publication number: 20170118824
    Abstract: A control system for wirelessly switching lamps over short distances includes a mobile device, a lamp control switch and a controlled lamp. A user holds the mobile device to approach or depart from the lamp control switch and continuously transmit a wireless signal according to a communication protocol. The lamp control switch receives the wireless signal according to the communication protocol and turns on or off a corresponding controlled lamp according to signal intensity of the wireless signal. The control system is operated when users travel among different environments. When users get close to the lamp control switch, the lamp control switch drives the controlled lamp to turn on or off, and when users depart from the lamp control switch, the lamp control switch automatically turns off the controlled lamp, thereby ensuring operational convenience, energy conservation and carbon reduction.

  • Patent number: 9184580
    Abstract: An arrester includes a switch and a lightning detection breaker connected to the switch. The lightning detection breaker includes a metal conducting terminal electrically connected to an earth return, a DC power supply terminal, a ground terminal and an output terminal. When the power supply is under a lightning strike, a potential difference of both the DC power supply terminal and the ground terminal of the lightning detection breaker will go up to several thousands of volts. However, a voltage of the metal conducting terminal will not go up because the metal conducting terminal is electrically connected to the earth return. The switch will automatically become open circuit by the lightning detection breaker, and therefore an electronic device connected to the arrester is protected from damage done by the lightning.

  • Patent number: 8847510
    Abstract: An LED AC driving circuit capable of adjusting operating voltage has a rectifying unit, an LED unit, a voltage-controlled transistor, a current detecting unit and a current regulating unit to form a power loop. Further, a resistance adjusting unit is connected to the voltage-controlled transistor in parallel. The current regulating unit detects the operating power of the voltage-controlled transistor. When the detected operating power is zero, the resistance of the resistance adjusting unit is increased for increasing the current flowing through the voltage-controlled transistor. When the detected operating power becomes larger than a maximum rated power, the resistance of the resistance adjusting unit is decreased to reduce the current. Thus, the operating power is maintained between zero and the maximum rated power.
