Illumination in commercial buildings

Illumination in commercial buildings is crucial for creating functional, safe, and aesthetically pleasing environments.
Proper lighting design ensures that spaces are adequately lit for their intended use, enhances productivity, and contributes to the overall comfort and experience of occupants.
Lenses are used in lighting fixtures to control brightness and spread light evenly across a surface.
Adequate light levels are essential for different activities. For example, office work may require around 300-500 lux, while areas like hallways or storage rooms may need less.
The color temperature of lighting affects the ambiance and functionality. Cooler temperatures (e.g., 4000K) are often used in office settings for alertness and productivity, while warmer temperatures (e.g., 2700K) may be used in areas requiring a more relaxed atmosphere.
By using lenses, you can minimize the effects of spotlighting, where light is concentrated in specific areas, and achieve a more uniform light distribution throughout the space.
This helps in reducing shadows and ensuring that all areas are evenly illuminated.
