| 20090224691 | Apparatus and Method For Providing an Isolated Set Point from an Input Signal Applied to a Lamp Ballast - The present application discloses a method and apparatus for providing an isolated set point from an input signal. The set point can control the amount of power applied to a lamp via a lamp ballast. An AC output signal from the ballast powers a dimming circuit. The AC signal is coupled across an isolation transformer and subsequently converted into a DC signal. This DC signal is loaded by a variable resistor, which creates a voltage differential across the resistor. This voltage differential is then seen across DC input terminals of the ballast, and it is across the DC input terminals that the set point is created. By varying the value of the resistor, the ballast set point is varied ultimately changing the power that is applied to the lamp by the ballast. | 09-10-2009 |

| 20100102751 | INTELLIGENT LIGHT FIXTURE FACILITATING UNIVERSAL LIGHT BULB - An intelligent light fixture facilitates the use of a ‘universal’ light bulb having a wattage rating. A lamp dimmer circuit disposed within the fixture is in electrical communication between the AC line and a socket. A bulb test circuit within the fixture is operative to determine the maximum wattage of the bulb. A controller, also within the fixture includes a wattage select input. The controller is operative to determine the maximum wattage of the bulb using the bulb test circuit, compare the maximum wattage to the wattage select input and, if the maximum wattage is greater than the wattage select input, control the dimmer circuit to ensure that the power delivered to the bulb does not exceed the wattage select input. The bulb test circuit may determine the maximum wattage of the bulb by measuring the resistance of the bulb's filament or alternatively, by temporarily impressing line voltage across the bulb and measuring the current drawn by the bulb's filament. Alternative embodiments provide a wattage dial disposed on an adapter unit or directly on the threaded base of a bulb. | 04-29-2010 |
