| Title: |
Lighting System With Lighting Dimmer Output Mapping |
| Abstract: |
A system and method map dimming levels of a lighting dimmer to light
source control signals using a predetermined lighting output function.
The dimmer generates a dimmer output signal value. At any particular
period of time, the dimmer output signal value represents one of multiple
dimming levels. In at least one embodiment, the lighting output function
maps the dimmer output signal value to a dimming value different than the
dimming level represented by the dimmer output signal value. The lighting
output function converts a dimmer output signal values corresponding to
measured light levels to perception based light levels. A light source
driver operates a light source in accordance with the predetermined
lighting output function. The system and method can include a filter to
modify at least a set of the dimmer output signal values prior to mapping
the dimmer output signal values to a new dimming level.
