- •
The potential of LED SAHP oriented system parameters to enhance VLC energy efficiency is investigated.
- •
Four LED alignments of the same total LEDs are deployed and their performances are compared.
- •
Types of optimizations are designed to gain better tradeoff between efficiency and SNR variations.
- •
VLC with narrow SAHP LEDs can save more than 40% energy consumptions compared to the traditional dimming situation.
