摘要:
A non-contact power system transfers power and signals simultaneously. The signals control the non-contact power system. And an operational frequency is operated on a resonant frequency so that there is no voltage alternating on power switch and power loss is reduced.

A power-diode driver uses a single power source to supply power to the sub-drivers inside. The sub-drivers are well isolated so that they can be safely and easily expanded by connecting to other device or driver. Thus, the power-diode driver has a changeable turn-on time and a highly modulated assembly. And, hence, the present invention is suitable for mass producing reliable power-diode drivers.

摘要:
A method of arranging light emitting diodes (LEDs) supplied by AC power with low loss and smooth illumination in a high expandable structure is disclosed. The method includes the steps of: building up a virtual grid having M virtual lateral lines and N virtual vertical lines, which form multiple virtual intersection nodes at the intersections; disposing N−1 lateral LEDs in each virtual lateral line with one lateral LED placed between two adjacent virtual intersection nodes, connecting the positive terminal of one lateral LED to the positive terminal of one of the two adjacent lateral LEDs, and connecting the negative terminal of the one lateral LED to the negative terminal of the other adjacent lateral LED; disposing M−1 vertical LEDs in each virtual vertical line except the first and last virtual vertical lines with one vertical LED placed between two adjacent virtual intersection nodes, connecting the positive terminal of one vertical LED to the positive terminal of one of the two adjacent vertical LEDs, and connecting the negative terminal of the one vertical LED to the negative terminal of the other adjacent vertical LED; and connecting the AC power to the first and last virtual vertical lines. All vertical LEDs are turned on by the AC power and about one half of the lateral LEDs are turned on and the other half off during the positive phase of the AC power, and alternatively, the about one half of the lateral LEDs are turned off and the other half on during the negative phase of the AC power. Therefore, the vertical LEDs are always turned on and the lateral LEDs are alternatively turned on and off.
