The illumination requirements (Lux) in different areas of a supermarket vary according to function and traffic volume, and usually follow the following international standards (such as CIE or EN standards) and practical application recommendations:
1. General sales area
Recommended illumination: 500-750 Lux
Note: The main channel and product display area require uniform bright light to ensure that the products are clearly visible and the colors are true (color rendering index CRI ≥ 80).
2. Fresh food area (meat, seafood, fruits and vegetables)
Recommended illumination: 750-1000 Lux
Note: High illumination highlights the freshness of ingredients. The meat area can be matched with warm light (3000K color temperature), and the fruit and vegetable area should use cold white light (4000-5000K).
3. Cashier counter
Recommended illumination: 750-1000 Lux
Note: To ensure transaction security and efficiency, shadows must be avoided (such as banknote recognition).
4. Shelves and promotion areas
Vertical illumination: 300-500 Lux (side supplementary light)
Note: Key products or promotional piles can be partially increased to 1000 Lux to attract attention.
5. Warehouse and backstage areas
Recommended illumination: 200-300 Lux
Note: Basic lighting is sufficient, but 300-500 Lux is recommended for the sorting area.
6. Other areas
Entrance/exit: 300-500 Lux (transitional natural light)
Corridor/stairs: 200 Lux (safety requirements).
Notes:
Energy-saving design: LED lamps are preferred, with sensors (such as lowering the illumination in areas with low traffic).
Regulatory reference: It must comply with local building lighting standards ( stipulates that the general area of the supermarket is ≥300 Lux, and the actual operation is often higher than this value).
Reasonable planning of illumination can improve customer experience while balancing energy consumption costs. It is recommended to combine professional lighting design for field measurement. you can ask http://www.benweilight.com to design the lux for your supermarkt
