Abstract: Electronic ballasts, driver apparatus, and methods are provided in which a heating current is generated by the driver to power a resistive heating element of an insulation detector associated with a recessed can fixture using a regulated current source/sink circuit.

Abstract: A lighting control system is coupled to one or more ballast/drivers operating one or more light sources. A low power control module receives analog, digital and/or DALI signals from one or more sources, processes the signals to provide an appropriate lighting response and outputs one or more commands related to light output of the one or more ballast/drivers operating one or more light sources. A gateway component receives wireless signals from the low power control module to relay to one or more control components. The control components provide instruction to modify the light output of the one or more ballast/drivers operating one or more light sources based at least in part upon the one or more commands received from the low power control module and/or the gateway component.

Abstract: Systems and methods are disclosed that facilitate switching a lamp ballast between DALI and analog control states as a function of control state information stored prior to the ballast being powered of and control information received by an interface circuit for the ballast circuit. A depolarization circuit is coupled to the interface circuit and ensures consistent polarity across a rectifier circuit regardless of the polarity of two control wires coupled to a miswiring protection circuit in the interface circuit. In this manner, a single interface circuit provides dual 0-10V analog and DALI control for dimming a lighting device regardless of whether a wall-mounted controller coupled to the interface circuit is an analog or a DALI type controller, thereby mitigating a need to switch out a ballast circuit coupled to the lighting device when changing between DALI and analog type controllers.
