Abstract:Outdoor LED advertising screens have a high power con- sumption. Those installations can easily reach a power den- sity of 1kW per square meter. This causes not only high electricity costs for the operator but also pollutes the envi- ronment with stray light. As the high power consumption is mainly caused by incorrect brightness settings, better con- trol loops could improve the situation. In this paper we pro- pose first steps towards improved brightness control loops which could lead to significant reductions of power consump- tion 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%.
