5.3. LED module constant lumen output (CLO)
This feature allows a gradual increase curve of the output current over time to be defined for the constant lumen
output depreciation of the LED module.
To correctly use and configure this functionality, the depreciation curve of the LED module lumen output to be
supplied must be known. This curve can differ for the different LED modules on the market and depends on both the
operating point and the thermal conditions under which it is working.
Based on this information, a table can be defined to incrementally assign an output current value for each operating
interval, so that the loss of LED module lumen output during that period is compensated.
The output current value can be assigned in increments of 1% within a range from 0 to 100%, where 100% is the value
defined by the AOC. The intervals can be configured in steps of 500 hours.
To synchronise the compensation curve configured by the CLO with the actual lumen output depreciation, the MOT
parameter, “the LED module operating time”, must be entered so that it coincides with the actual operating hours of
the LED module.
WARNING: The MOT value is also used for the EOL functionality.
