Abstract: The invention relates to a lighting system of alternate current light-emitting diodes (AC-LEDs). The system includes a first, a second and a third AC-LED modules, each two of them being electrically connected in parallel to one another and further electrically connected to a first, a second or a third phase voltage input terminal. The respective AC-LED modules include a first and a second LED modules. The system is further provided with rectifier circuits and multi-stage driver modules. The invention involves driving the AC-LED modules to emit light in an alternate manner using a three-phase AC power source, thereby reducing the flicker index, and further driving the first and the second LED modules to light up in different alternating orders, thereby rendering the light emission of the AC-LED lighting system substantially constant in terms of power and brightness.

Abstract: The present invention involves use of at least two unidirectional elements to provide flow paths for the positive half cycle and the negative half cycle of the AC power input, respectively, and the at least two LED modules are integrated in the flow path of the positive half cycle and the negative half cycle, respectively, and a multi-stage driver module is integrated, so that when the positive half cycle or the negative half cycle is conducting, the at least two LED modules are lit up in different alternating orders, thereby rendering the light emission of the at least two LED modules substantially identical in an AC power cycle in terms of power and brightness. The invention overcomes the problem of uneven brightness of the LED lighting apparatus using a conventional multi-stage driver device.

Abstract: An after-sales system platform provides business modeling functions to enhance commercial values as a measure for deriving business direction, and includes multiple front-end data providing units, a cloud platform and a client service server. The front-end data providing units provide relevant information. The cloud platform has multiple category databases and an information screening unit and categorizes the relevant information and stores the relevant information in the respective category databases. The client service server acquires categorized information through the information screening unit by request. The categorized information can be used for a multi-oriented business model including service policy making, business assessment, and research and development management. The system platform employs innovative concepts of vehicles and remotely piloted vehicles and is implemented on the basis of an on-board diagnostic II.

Abstract: The present invention involves utilizing AC power lines adapted for connection to an AC power source and a signal line to perform baseband signal transmission and communication. According to the invention, a threshold voltage is provided as a comparison reference for an AC input voltage to determine whether the communication is permitted. If the AC input voltage is greater than the threshold voltage, the communication is permitted. On the contrary, if the AC input voltage is smaller than the threshold voltage, the communication is not permitted. By virtue of the invention, the initiation time and the termination time of the baseband signal communication for each load tend to be substantially identical. Reliability is thus increased and noise interference problem is not created.

Abstract: An intelligent, cloud-based and real-time vehicle care system has a vehicle diagnostic device, a remote server and a user device. The vehicle diagnostic device is mounted in a vehicle and has a control unit and a wireless transmission unit. When the control unit receives a trouble code from a diagnostic system or determines that the vehicle encounters trouble based on vehicle information received from a CAN bus system, the control module provides trouble diagnostic information to the remote server, and then the remote server transmits the trouble diagnostic information to the user device. Therefore, the user can operate the user device to review whether the vehicle encounters trouble in real-time.

Abstract: A heat-dissipating lamp cap of a light-emitting diode (LED) tube has a tubular portion and a cap portion. The tubular portion has an annular wall and two openings. The annular wall has a heat-dissipating portion defined as a portion of the annular wall extending axially between the two openings and aligning with electronic elements over one end of the LED tube. The cap portion covers one of the openings of the tubular portion and has two electrodes and a conducting resilient piece. The conducting resilient piece has an electrode connection portion electrically connected to the electrodes and an abutting portion electrically connected to the LED tube. When the LED tube is operated, heat generated by the heating elements on ends of the LED tube can be dissipated through the heat-dissipating portion of the heat-dissipating lamp cap.
