Light plays a central role in the design of a visual environment. The architecture, people and objects are all made visible by the lighting. Light influences our well-being, the aesthetic effect and the mood of a room or area.
Visible radiant power emitted by a light source
Efficacy of a lamp
Measure for the luminous flux emitted per solid angle
Luminous flux density on a surface
Product of the illuminance and the exposure time
Having technical knowledge about lamps will help to make the right selection with regards to brilliance, colour rendition, modelling ability and energy efficiency. The spectrum ranges from thermal radiators through to semiconductor spotlights.
Luminaires perform a range of functions. The most important task of a luminaire is to direct the lamp's luminous flux. The objective here is to distribute light in a way that best suits the particular tasks of the luminaire while making the best possible use of the energy expended. In addition to design-related aspects of luminaires as a constituent part of a building's architecture, those aspects relating to installation and safety are also relevant.
