摘要： A self-heating thermal protector operates to disconnect a load control device for a lighting load from an AC power source when insulation is present around the insulation detector independent of the magnitude of an AC mains line voltage of the AC power source. The insulation detector comprises a temperature-sensitive switch and a constant power circuit that are located in a thermally-conductive enclosure. The temperature-sensitive switch is coupled between the AC power source and the load control device and is rendered conductive and non-conductive in response to a temperature inside the enclosure. The constant power circuit is coupled in parallel with the AC power source and dissipates a constant amount of power independent of the magnitude of the AC mains line voltage when the temperature-sensitive switch is conductive. Restricted airflow over the thermal protector causes the temperature inside the enclosure to increase, such that the temperature-sensitive switch is rendered non-conductive.

摘要： A multi-stage power supply for a load control device is able to operate in a low-power mode in which the power supply has a decreased power consumption when an electrical load controlled by the load control device is off. The load control device comprises a load control circuit and a controller, which operate to control the amount of power delivered to the load. The power supply comprises a first efficient power supply (e.g., a switching power supply) operable to generate a first DC supply voltage. The power supply further comprises a second inefficient power supply (e.g., a linear power supply) operable to receive the first DC supply voltage and to generate a second DC supply voltage for powering the controller. The controller controls the multi-stage power supply to the low-power mode when the electrical load is off, such that the magnitude of the first DC supply voltage decreases to a decreased magnitude and the inefficient power supply continues to generate the second DC supply voltage.

The feedback circuit generates at least one load current feedback signal representative of the magnitude of the load current. The regulation transistor operates in the linear region to control the magnitude of the load current conducted through the load in response to the magnitude of the load current determined from the load current feedback signal.
