Dim, how?
The output of this project will be a book in the series of little blue on lighting controls. The book is aimed at designers of practical lighting systems as a guide to achieving optimal energy savings in dimmed LED-systems. It includes new research in light level perception, automation and user interfaces, and research in power usage and flicker. The handbook must bring out the full potential of modern dimming systems while preserving optimal user conditions.
Lighting controls are the new hype in the lighting industry, they go well with LED systems and provide energy savings potentials. LEDs have become very efficient the last couple of years but most of the prognoses imply that the efficiency will stabilise at around 200 lm/W. The next important area for energy efficient lighting will therefore be intelligent and user oriented lighting controls.
Dimming has a couple of factors that can be put to good use with regards to energy savings. Previous research shows that dimming can be executed to a large extent without the users experiencing the magnitude of the dimming process. Dimming of especially LED’s has mainly two disadvantages: the drivers electronics may cause flicker and total harmonic distortion can result in less energy savings than anticipated.
The little blue on lighting controls is aimed at designers of practical lighting systems. The book is a guide on how to achieve optimal energy savings in LED-systems by dimming indoors as well as outdoors. The book will focus on responsible light conditions by addressing occupant perception of dimming in relation to energy saving potentials while preserving detection of colour and details with regard to safety.
In an efficient lighting system (indoor as well as outdoor) that includes occupant detection and daylight harvesting, the energy savings can amount to 50% - 70%. During renovation projects this saving opportunity is often neglected due to start cost of the advanced systems. This handbook aims to inspire to take advantage of this valuable energy savings potential.
The output of this project is a booklet in the series of ‘the little blue’ and this one is about lighting controls. The booklet is aimed at designers of practical lighting systems as a guide to achieving optimal energy savings in dimmed LED-systems. It includes research on light level perception, automation and user interfaces, and research in power usage and flicker. The booklets focus is to provide guidance in how to achieve the maximum energy savings potential of modern dimming systems while preserving optimal user conditions.
