Abstract: A flyback power converter includes a power transformer, a first lossless voltage conversion circuit, a first low-dropout linear regulator and a secondary side power supply circuit. The first low-dropout linear regulator (LDO) generates a first operation voltage as power supply for being supplied to a sub-operation circuit. The secondary side power supply circuit includes a second lossless voltage conversion circuit and a second LDO. The second LDO generates a second operation voltage. The first operation voltage and the second operation voltage are shunted to a common node. When a first lossless conversion voltage is greater than a first threshold voltage, the second LDO is enabled to generate the second operation voltage to replace the first operation voltage as power supply supplied to the sub-operation circuit; wherein the second lossless conversion voltage is lower than the first lossless switching voltage.

Abstract: A system for synchronizing lighting effect patterns of interactive lighting effect devices at a remote location with respect to those at local location is disclosed herein. Synchronized lighting effects produced at the remote location while watching a lighting effect show using other interactive lighting effect devices illuminated according to a script at event venue, can be achieved. Such synchronized lighting effects obtained at remote location generate a corresponding virtual simulated perception of attending same concert venue live when watching a live streaming video thereof. Low latency between lighting effect changes are produced at remote location with respect to those observed in concert venue live streaming video due to method of color control signal generation along with usage of color control pattern blending module that creates a blended video frame comprising of a color control pattern, which allows for efficient lighting effect pattern generation at remote location.

Abstract: Interactive lighting effect devices configured by an interactive lighting effect control system in an automated wireless manner on a mass scale are provided. RF data bursts are captured to illuminate interactive lighting effect devices selectively in accordance with a matched data. The matched data is formed by combining a pattern-related data of lighting effect extracted from a QR code of the event ticket with an identification address extracted from a QR code of the interactive lighting effect device, the pattern-related data of lighting effect includes a zone code. Improvisational illuminating color control change for any zone assignment for color control signal can be generated and converted to set of RGB color codes to be transmitted by the interactive lighting effect control system for broadcasting as data bursts to the interactive lighting effect devices. Different types of data acquisition interfaces are provided for obtaining the matched data.
