general lighting design approaches
According to Russian standards, the minimum level of illumination in the trading floor should be 200 - 400 lux, depending on the type of retail space.
However, taking into account the presence of accent lighting, the location of the object and its target positioning, the level of illumination can be significantly increased and, as a rule, is selected individually for each brand. Illumination is normalized on a horizontal surface located at a height of 0.8 m from the floor level.
Trade facilities in the large-format retail segment have an increased energy intensity. If we talk about the lighting installation, then the maximum energy consumption falls on the general lighting system. A competent choice of the type of lighting device can significantly reduce energy costs, as well as the cost of installing and operating equipment.
The optimal type of lighting device for large retail spaces is a trunk system. Devices of this type are easy to install and maintain. A variety of accessories makes it possible to build light lines and structures of various configurations, and the presence of through or main wiring allows you to minimize the number of electrical connection points. For stores with a permanent commodity exposition, a longitudinal arrangement of lighting equipment is recommended. This approach allows the most efficient use of the luminous flux from the devices. In addition, only with this arrangement can luminaires with biasymmetrical and asymmetric light distributions be used. If the object is characterized by frequent rearrangement of rack equipment, it is preferable to place the fixtures perpendicular to the racks.
