Abstract

In this paper, we consider multi-datastream VLC networks serving dense IoT deployments and propose a "dome bulb" that consists of a multi-LED array with a dome-shaped lens structure to separate each LED's beam for spatial reuse. Each LED has Lambertian irradiance distribution that can be collected and directed to receiver location using a wide field-of-view (FOV) lens system. Within the FOV, each LED's divergence angle is narrowed to improve spatial reuse, which also brings the problem of spotty lighting. We analyze the dome bulb in terms of illumination uniformity and Signal-to-Interference-Noise Ratio (SINR) provided to receivers in the room. We also present a channel model based on the simulated SINR.
