摘要：

In order to evaluate the energy saving ability of the visible light communications (VLC) system, we employed optimizations with different parameters for two LED alignments. We choose SC-4PPM modulation scheme to implement the dimming control. By minimizing energy efficiency, with respect to LED semi-angle at half power (SAHP) and LED position parameter, along with modulation parameters b and c, in the condition of maintain communication and lighting requirement, we obtained optimal energy efficiency. The results show that, the energy saving can be improved above 30% over the non-optimized (NOP) situation, for both the LED ring alignment and LED ring-corner alignment.
