LED Maintenance of the lighting

The maintenance factor takes into account:

• the decrease in luminous flux due to failure or aging of luminaire

• the possible soiling of a luminaire ofer time
• the spatial and external conditions that can contribute to pollution and aging
• Duration of the maintenance cycle
• operating times
• Lifetime of the system
  

Example:
With a maintenance factor of 0,5, a system must initially generate twice the luminous flux so that it delivers the illuminance required in the relevant standard up to the first mainentance . The extra brightness in the installation is also referred to as luminous flux buffer.
