  • LOW INTENSITY DIMMING CIRCUIT FOR AN LED LAMP AND METHOD OF CONTROLLING AN LED
    Publication number: 20140184076
    Abstract: A driver is connectable to an external power supply and configured to output a variable driving current for one or more loads, such as LEDs. A low intensity dimming module is operable to divert some or all of the driving current away from the LEDs when a user selects a very low level of light intensity so that the driver has a constant minimum load. The low intensity dimming module prevents performance issues that commonly affect drivers under light load conditions.

  • THERMAL PROTECTION DEVICE
    Publication number: 20140185175
    Abstract: A thermal protection device includes a heating circuit that develops a first heat magnitude when exposed to a temperature below a threshold and further develops a second heat magnitude greater than the first heat magnitude when exposed to a temperature above the threshold. A thermal circuit breaker is disposed in heat communication with the heating circuit and has component having a holding temperature greater than the threshold and a trip temperature greater than the holding temperature.
