Abstract

Outdoor LED advertising screens have a high power consumption. Those installations can easily reach a power density of 1kW per square meter. This causes not only high electricity costs for the operator but also pollutes the environment with stray light. As the high power consumption is mainly caused by incorrect brightness settings, better control loops could improve the situation. In this paper we propose first steps towards improved brightness control loops which could lead to significant reductions of power consumption as well as stray light. A first evaluation shows that our proposed solution reduces the power consumption of large LED advertising screens by up to 25%.
