Abstract: A lighting control device for controlling the light intensity level of at least one lamp is disclosed. The lighting control device includes 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. The first fade rate is based on a predefined fade-off time.

Abstract: A lighting control device for controlling the light intensity level of at least one lamp is disclosed. The lighting control device includes an actuator and a controller, such as a microcontroller, for example. The controller is operable to cause the light intensity level of the lamp to fade at a first fade rate when the actuator is actuated. If the controller determines that the actuator has been actuated for at least a predefined hold time, the controller causes the light intensity level of the lamp to fade at a second fade rate for a predefined long fade time. After the long fade time elapses, the controller causes the light intensity level of the lamp to fade to off at a third fade. The first fade rate is based on a predefined fade-off time that represents a time allotted for fading the light intensity level of the lamp from its initial light intensity level to off.

Abstract: An independent radio frequency programming device automates a setup process for a lighting system with lighting control devices and master controls. The programming device intercepts communications between the lighting control devices and the master control during an initial setup phase. A start function permits the programming device to provide automated setup information to the master controls. Once the automated setup process completes, the lighting system is fully programmed with behavior functions for all lighting control devices.

Abstract: A lighting control device for controlling the light intensity level of at least one lamp is disclosed. The lighting control device includes a microcontroller and a user-actuatable switch controller that is operatively coupled to the microcontroller. The microcontroller causes the light intensity level of the lamp to fade at a first fade rate when the switch controller is actuated. If the microcontroller determines that the switch controller has been actuated for at least a predefined actuator hold time, the microcontroller causes the light intensity level of the lamp to fade at a second fade rate for a predefined long fade time. After the long fade time elapses, the microcontroller causes the light intensity level of the lamp to fade to off at a third fade. The first fade rate is based on a predefined fade-off time that represents a time allotted for fading the light intensity level of the lamp from its initial light intensity level to off.

Abstract: A method for operatively interconnecting a first and second lighting control subnet is disclosed. In the method, a link claim is transmitted to the first and second lighting control subnets from a bridge. The link claim directs the first and second lighting control subnets to wait for a lighting control command, which is transmitted to the lighting control command to the first lighting control subnet. A random wait time is assigned to the first lighting control subnet and a maximum random wait time is assigned to the second lighting control subnet. Finally, an acknowledgement is received from the first lighting control subnet.
