The three-phase LED lighting system utilizes the pulsating voltage obtained from three-phase alternating current power that has been fully rectified by a three-phase full-wave rectified DC power supply to illuminate LED lamps. Since three-phase alternating current has less voltage fluctuation compared to single-phase alternating current, there is no flickering when illuminating LED lamps with the direct current power (pulsating current) that has only been fully rectified (there are no parts below 5% of the peak value of light output). Installation Method: The direct current power (pulsating current) output from the three-phase full-wave rectified DC power supply can be easily supplied to the LED lamps using the existing mercury lamp circuit. ☆ Features of the Three-Phase LED Lighting System: ■ It does not use components with a limited lifespan, such as capacitors that degrade due to thermal factors, allowing it to be used in high-temperature environments. ■ The DC power obtained from fully rectifying three-phase alternating current does not generate harmonics. ■ Similar to direct current, even though it is pulsating current, the fluctuation range of the output voltage is small, preventing flickering. ■ There is no noise generation because it does not use electronic circuits or electronic components that can be sources of noise. ■ Three-phase alternating current has high transport and utilization efficiency, which reduces voltage drop. ■ The entire system is composed of analog circuits that are resistant to surges and noise.
