Beyond the Physical Limit Energy Saving Lighting and Illumination by Using Repetitive Intense and Fast Pulsed Light Sources and the Effect on Human Eyes

By using Blue, Green and Red LEDs it is shown that the Broca-Sulzer effect holds for a repetitive pulse operated LED lighting system. In other words Talbot-Plateau Law does not hold. The effective enhancement at 60 Hz with a 5% duty ratio is about 1.5 to 2.7 times that of DC operation for blue and g...

Summary:By using Blue, Green and Red LEDs it is shown that the Broca-Sulzer effect holds for a repetitive pulse operated LED lighting system. In other words Talbot-Plateau Law does not hold. The effective enhancement at 60 Hz with a 5% duty ratio is about 1.5 to 2.7 times that of DC operation for blue and green light. This result suggests that pulsed operation can be a way to solving the energy saving problem of lighting.
