Tailored lighting is economical lighting
Addressing lighting tasks intelligently: lighting management makes for flexible lighting, lighting tailored to needs, visual ergonomics, user orientation and a sense of wellbeing. It enables lighting scenes to be programmed according to requirements. They can be simply activated by a switch or remote control or automatically controlled to take account of available daylight.
The conference room is a typical application for lighting management. As a general rule, it presents various lighting assignments – general lighting, lecture lighting and orientation lighting for presentations with video beamers – with different requirements in terms of brightness levels. Dimmable lighting and the possibility of operating individual luminaires or groups of luminaires separately are fundamental requirements for convenient lighting management.
Lighting management also helps the environment: having lights burning in unused rooms is a waste of energy. Motion detectors switch lighting off when no movement is registered and activate it again when a person enters the room. The saving potential of this presence control can be as high as 50 percent.
Incorporating daylight
Even more energy– as much as 60 percent – can be saved by installing a daylight-dependent control system. This enables artificial lighting to be partially or even fully dimmed in response to changes in available daylight. The components of this kind of lighting regulation system include dimmable EBs and signal amplifiers with light sensors. There are also innovative systems available for optimising utilisation of daylight. Specular reflectors or prisms, for example, can be used to direct natural light deep into the room.
Extensive information on the subject of lighting management is contained in booklet 12 "Lighting Quality with Electronics".
Dynamic lighting: stimulating, relaxing, mood-inducing
A new trend is being set by dynamic lighting. Taking its cue from nature, it is a concept using innovative lighting technology to recreate the rhythm of daylight. Dynamic lighting can be specifically tailored to physical requirements. Natural light changes in brightness over the course of the day and, in doing so, influences the production of hormones in the human body and the phases of activity and rest that make up our daily routine.
Like its natural role model, dynamic lighting relies on changes in light. For example, in an office: the lighting atmosphere is stimulating in the morning, relaxing at midday, bright for renewed concentration in the afternoon and lowered for a mellower mood at the end of the working day.
Combination of warm-white and daylight-white light
Dynamic lighting systems work with a combination of fluorescent lamps for warm-white and daylight-white lighting. They can steplessly produce any light colour from 2,800 to 6,000 Kelvin at various illuminance levels. Dynamic lighting is already an established constituent of sophisticated lighting concepts.
