Abstract:
1. A solid-state light emitting device having controllable multiphase reactive power, which utilizes a three-phase AC power source, each power phase respectively driving individual solid-state light emitting members arranged adjacently or arranged with an overlapping means, so that the synthetic illumination brightness is overlapped through the illumination brightness waveforms generated by the AC power voltage of each phase, lowering the synthetic pulse rate of illumination brightness, and the sine waveform voltages at different phases between each power source enable the individual solid-state light emitting members respectively driven by each phase and arranged adjacently or arranged with an overlapping means generate optical energy having different brightnesses with respect to the instant value of the voltage waveform; such that when the individual solid-state light emitting members having different brightness and arranged adjacently or arranged with an overlapping means emit light, the power passing through the individual solid-state light emitting member having a relatively low brightness is defined as reactive power; the solid-state light emitting device having controllable multiphase reactive power that utilizes a solid-state switch device ( 2000 ) connected in parallel between positive and negative terminals of a respective single-phase bridge rectifier (BR 100 ) to control an AC conductivity phase angle for controlling the reactive power to be cut so as to save power, and to further regulate the current and voltage supplied to the individual solid-state light emitting member; wherein each power phase of the three-phase AC power source is regulated by the solid-state switch device ( the AC solid-state light emitting member ( the AC current limiting circuit device (Z the solid-state switch device ( an electric power control unit (ECU): according to the internal setting of the electric control unit (ECU) or receiving external controls, and referring to the voltage of power source and the current passing through the AC current limiting circuit device (Z
