Abstract

In existing indoor & outdoor visible light communications (VLC) works, the LED luminaries are almost all modeled following conventional Lambertian beam pattern. However, for providing energy efficient illumination and controlling lighting pollution, the beam patterns of the commercially available LED street luminaries are almost all application-oriented designed which can only be profiled by more sophisticated mathematical representation. In this paper, for the first time, to the best of our knowledge, the link coverages of the outdoor VLC with actual LED street luminaries are modeled and evaluated. Numerical results identify that, compared to the conventional Lambertian case the beam pattern of typical actual LED street luminary is superior to concentrate the emitted power in the served cell by sharp cell edge, naturally limit the inter cell interference to quite low level and provide highly link quality uniformity within each cell.
