Abstract
A control system comprises a switch and a control module that communicates with the switch and that samples a filament resistance of a fluorescent light when the switch is off and that selectively increases current supplied to the fluorescent light above a nominal current value during turn on based on the filament resistance.
Claims45
A control system comprising:
- a switch;
- and
- a control module that communicates with said switch and that samples a filament resistance of a fluorescent light when said switch is in a first state and that selectively increases current supplied to the fluorescent light above a nominal current value when said switch transitions to a second state based on said filament resistance.
A method for operating a fluorescent light, comprising:
- sampling a filament resistance of a fluorescent light when said fluorescent light is off;
- and
- selectively increasing current supplied to the fluorescent light above a nominal current value during turn on based on said filament resistance.
A control system comprising:
- switch means for switching;
- and
- control means that communicates with said switch means for sampling a filament resistance of a fluorescent light when said switch means is in a first state and for selectively increasing current supplied to the fluorescent light above a nominal current value when said switch means transitions to a second state based on said filament resistance.
