Lighting Maintenance
To assure lighting quality, whether for task performance, safety, or aesthetic reasons, proper maintenance is required. Lack of maintenance can have a negative effect on human performance, perception of an area, safety, and security. It can also waste energy. The combined effect of equipment age and dirt depreciation can reduce illuminance by 25% to 50% or more, depending on the application and equipment used.
Maintenance Programs
| Program | Description |
|---|---|
| Group relamping | Group relamping entails replacing all of the lamps in a system together after a fixed interval, called the economic group relamping interval. Group relamping can reduce the cost of operating a lighting system while keeping illuminance levels close to the design value. |
| Periodic planned cleaning | Cleaning the lighting system usually entails washing or otherwise removing dirt from the luminaries, occasionally cleaning and repainting room surfaces, and occasionally cleaning air supply vents to prevent unnecessary dirt distribution. |
