Abstract: A printed circuit board set having high-efficiency heat dissipation includes a printed circuit board (PCB) and a heat dissipating device. The PCB has multiple electronic elements, at least one heat dissipating hole, and at least one thermally conductive material. The electronic elements are disposed on the top surface of the PCB. Each of the at least one heat dissipating hole is formed through the top and bottom surfaces of the PCB and aligns with one of the electronic elements. Each of the at least one thermally conductive material is disposed in the corresponding heat dissipating hole and in contact with the corresponding electronic element. The heat dissipating device is attached to the bottom surface of the PCB and in contact with the at least one thermally conductive material. With a high thermal conductivity, the at least one thermally conductive material rapidly transfers the waste heat produced by the PCB in operation to the heat dissipating device for heat dissipation.

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.

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: 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.
