Example 3:
Shop with exclusive accessories in a pedestrian zone

The evaluation surface of the shop stretches from the pedestrian zone directly in front of the shop to the interior rear wall, where there is a backlit presentation of goods. In this situation too, we proceed from the lowest luminance value directly in front of the shop in the pedestrian zone. The entrance is flanked by two shop windows whose illumination is adjusted to the level of daylight using a light control unit. The figure measured at floor level is 200 lx. The 500 lx mark is reached at the cash desk. This means relationships of 1 : 4 : 10. The goods on the side walls are presented with 20 times the luminance compared with the entrance. Very high quality products are to be found in the facing wall in integrated and backlit display cabinets. In front of these there are small tables for sales conversations. Here a degree of illuminance of 1800 lx is required. Proceeding from the lowest luminance value, this results in a relationship of 1 : 36. In this way, the customers’ attention is drawn directly to the goods.

 
 
 

a) Sales tables 36-fold luminance
b) Shelves 20-fold Luminance
c) Counters 10-fold Luminance
d) Floor 4-fold Luminance
e) Pedestrian zone 1-fold Luminance

 

In the shop window, the luminance is subject to daylight-dependent control.

In the shop, the relationships between the luminance levels vary greatly. Here too, the lowest luminance value is defined as 1. The resulting relationships are 1 : 4 : 10 : 20 : 36.
