Publication number: 20180017273Abstract: A smart ventilation fan device includes a fan, a light-emitting module, a sensor set, a wireless module and a control circuit. The fan includes a motor. The sensor set is for sensing environment information. The wireless module is for receiving a command signal from an electronic device and for transmitting the environment information and ventilation fan device information to the electronic device. The control circuit includes a micro-controller which is for generating a control signal according to the command signal received from the wireless module, so as to control the motor of the fan to rotate, and the micro-controller processes the environment information sensed by the sensor set and/or the ventilation fan information. The micro-controller of the control circuit transmits the environment information and/or the ventilation fan information to the electronic device through the wireless module. The invention further includes a smart ventilation fan system.Type: ApplicationFiled: October 18, 2016Publication date: January 18, 2018Inventors: Yueh-Shan LIN, Yen-Lin CHEN, Tsung-Wei CHEN

Patent number: 8928298Abstract: A power controlling method includes the following steps. A first Proportional Integral (PI) computation is performed according to an input current signal and command. Next, whether the input current signal is greater than a maximum rated charging current of a battery unit is determined to generate a switching signal for controlling a brake unit correspondingly. Then, a second PI computation is performed in accordance with the output voltage signal and a predetermined voltage command. Thereafter, the output voltage signal and the voltage command are compared to set an output current command selectively. Next, a third PI computation is performed in accordance with the output current signal and command to adjust a first pair of switching signals and a second pair of switching signals, such that a switching unit performs a corresponding switching action to adjust the output voltage signal. A power system and a power controlling apparatus are provide.Type: GrantFiled: January 17, 2012Date of Patent: January 6, 2015Assignee: Delta Electronics, Inc.Inventors: Chih-Hung Hsiao, Cheng-Chieh Chan, Ching-Yueh Yu, Yueh-Shan Lin

Patent number: 8770774Abstract: A ventilation fan with lights includes an exhaust fan, a lid, and an illumination apparatus. The lid covers an entrance of the exhaust fan. The lid has plural exhaust gratings and an opening. The exhaust gratings are arranged at least adjacent to opposite sides of the opening. The illumination apparatus is embedded in the opening of the lid. The illumination apparatus includes a lamp housing, a lamp plate, plural light emitting diodes (LEDs), a lampshade, and plural scattering microstructures. LEDs are arranged on the lamp plate. The lampshade covers the lamp housing. The lampshade and the lamp housing cooperate to define a lamp chamber therebetween. The lamp plate and the LEDs are disposed in the lamp chamber. The scattering microstructures are disposed on an inner surface of the lampshade facing the lamp chamber.Type: GrantFiled: January 16, 2012Date of Patent: July 8, 2014Assignee: Delta Electronics, Inc.Inventors: Long-Sing Ye, Yueh-Shan Lin, Wen-Hsiang Lin, Te-Chung Liu

Patent number: 8749185Abstract: A ventilation apparatus with a two-section feedback compensation control and a method for operating the same are disclosed. The ventilation apparatus includes a power conversion unit, a driven circuit, a DC motor, a current-sensing unit, a voltage compensation unit, and a control unit. The power conversion unit receives and converts an AC power voltage into a DC power voltage. The driven circuit receives the DC power voltage and outputs a driven voltage. The DC motor is driven through the driven voltage. The current-sensing unit senses an output current of the DC motor. The control unit receives the output current to compare to a threshold current value, thus controlling the voltage compensation unit. Accordingly, the DC power voltage is adjusted to adjust the speed of the DC motor.Type: GrantFiled: September 30, 2011Date of Patent: June 10, 2014Assignee: Delta Electronics, Inc.Inventors: Yi-Hua Lee, Yueh-Shan Lin, Yan-Lin Chen, Chih-Hua Lin, Te-Chung Liu
