Which lighting systems are the most suitable for sales areas?
Sales areas usually require good lighting to emphasise the merchandise on display. To achieve this the ratio of luminance between the object and the background should not be overlooked, which means that the object should be primarily illuminated with a beam of light directed in relation to the setting. In fact, if the background is equally lit, the eye will adapt to the average luminance, and the object will appear less illuminated.
As a consequence, lamps are used which have a narrow beam of light and high luminous intensity (on axis). Care must be taken when positioning a lamp so that no part of its beam dazzles. This is why discharge light sources are employed, which, as they are point-like sources, allow excellent control of the beam of light. Light points must be included that switch on again immediately in the event of a power failure (fluorescence), as well as light points with high colour rendering if colour is an important feature for the illuminated object. In this case, a halogen light source is preferable for excellent red colours. For example, Diapson recessed lamps can be used with various electrical connection options.
