The purpose of this paper is to increase awareness of the possibilities of an individual lighting system, especially concerning the energy savings to be obtained while maintaining optimal visual comfort and work performance. Conventional general lighting systems can be energy-efficient if highly optimized reflector designs and control gear are used. Local lighting systems can intrinsically offer energy savings by providing more light only where it is necessary (e.g. the desk) and less light where this is possible (e.g. rest of the room). However, numerous experiments have criticized the currently, available local lighting systems, mainly because of their poor ergonomic lighting quality. Neglecting the importance of ergonomics in lighting design would surely lead to false (energy) savings which would have, in the long run, quite the opposite effects. This presentation will show that local lighting can yield substantial energy savings without compromises towards a high ergonomic lighting quality and user-friendliness. For this purpose, a new concept for office lighting has been developed. The concept consists of three components which can be controlled individually by the user. Two components take care of the direct illumination of the task and are related to the desk or task area. The third component is used to light the surroundings, thus creating an ergonomically balanced and pleasant atmosphere in the working room. By dividing the lighting task over three different components, each of their optical systems can be optimized to satisfy its individual needs.. SUMMARY.
