1. A lighting control device for controlling a light intensity level of at least one lamp, the at least one lamp having an initial light intensity level, the lighting control device comprising:
an actuator; and
a controller operable to cause the light intensity level of the at least one lamp
to fade at a first fade rate that is based on the initial light intensity level of the at least one lamp upon a determination that the actuator has been actuated,
to fade to off at a second fade rate upon a determination that the actuator has been actuated for only a single transitory duration,
to fade from the initial intensity level to a preset desired intensity level at a third fade rate upon a determination that the actuator has been actuated for two successive transitory durations, and
to fade to off in a predefined fade rate sequence upon a determination that the actuator has been actuated for more than a transitory duration,
wherein the first fade rate is based on a predefined fade-off time, the fade-off time representing a time duration allotted for fading the light intensity level of the at least one lamp from the initial light intensity level to off.
2. The lighting control device of claim 1, wherein the controller is operable to cause the light intensity level of the at least one lamp to fade at a fourth fade rate for a predefined long fade time upon the determination that the actuator has been actuated for more than a transitory duration.
3. The lighting control device of claim 2, wherein the controller is operable to cause the light intensity level of the at least one lamp to fade to off at a fifth fade rate after the long fade time elapses.
4. The lighting control device of claim 3, wherein the fifth fade rate is a predefined rate at which the controller is operable to cause the light intensity level to fade from 100% to off over a predefined amount of time.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
