Selection of lighting fixtures for commercial premises

The role of general lighting fixtures is to provide the illumination required for the ambient lighting in the store, to achieve a bright and even effect in the store, and to relax the user, to relieve the spirit, and to ensure that the basic environment required for the walking and shopping environment is satisfied. Such lamps have downlights, chandeliers and embedded/ceiling lamps.

The role of display merchandise lighting fixtures is to increase the illumination to achieve higher brightness on products that are important or to be of interest to customers, to achieve the purpose of attracting customers' eyes or expressing the texture of the object, often referred to as emphasis/enhanced lighting. Depending on the volume or requirements of the object, the spotlights of different power and beam angles are used, and the luminaire is mounted at a position above the front of the object.

To sum up, the lights have the following common requirements:

1) Anti-glare structure.

Observation activities in a commercial establishment are very casual, and the eyes search for any items in the space that may be of interest. Therefore, when selecting lamps, pay attention to the glare level of the lamps through the brightness limit curve of the lamps, and also check the protection angle of the lamps. According to the installation position of the luminaire, under the premise of meeting the illuminance uniformity requirement and the energy saving requirement, the luminaire with a large protection angle is selected as much as possible to minimize the glare.

2) High color rendering requirements.

Under commercial lighting, the color of the product should be true, and the color rendering index should not be lower than 80.

3) UV protection.

In commercial places, lamps with high-intensity metal halide lamps are used as general lighting fixtures and partial accent lighting. Therefore, it is necessary to know the safety illuminance value of the luminaires for ultraviolet radiation, and application below the safety illuminance value will not cause ultraviolet damage. The use of luminaires with clear glass or plastic covers can effectively avoid UV radiation.

4) The spot of the spotlight.

The spot size (beam spread angle) and center intensity of the spotlight are two important indicators that must be adapted to the requirements of the illuminated object. Uniformity in the spot is also very important, and it is important to choose a luminaire that produces a uniform spot.
