Abstract: In this paper, we propose an indoor visible light positioning method with a large
number of LEDs which takes illumination into consideration. ID signals are designed and
10 transmitted in groups to achieve high positioning accuracy. The influence of different number of
LEDs on positioning accuracy is analyzed thereafter. LEDs are individually scaled by an
optimization factor to overcome the illumination performance degradation problem induced by
applying massive LEDs. Simulation results show that high accuracy positioning is possible with
moderate amount of LEDs without degrading illumination performance.
