Abstract: Methods and systems for illuminating an occupied spaces are disclosed, including, in one general aspect, an illumination method for illuminating a space to be occupied by one or more occupants that includes driving a first illumination element designated as an illumination level element, driving a second illumination element designated as a biological element, and continuously adjusting the steps of driving the first illumination element and driving the second illumination element to continuously adjust illumination levels and biological effects over time. The step of continuously adjusting can adjust biological effects without significantly changing perceived illumination quality.

Abstract: A strike barrier for use in an LED retrofit lamp is provided. The present invention provides the strike barrier with two silicon controlled rectifiers (SCRs) whose input is connected to a bridge rectifier and output is connected to a string of LED through a Zener diode. The strike barrier is compatible with UL ANSI requirement for a normal mode and an abnormal mode.

Abstract: The present invention provides a method for minimizing a ripple current and turning the light emitting diode (LED) OFF rapidly in order to maximize the efficiency of a light emitting diode array. To achieve this, a set of dual drain field effect transistor circuit is included with a light emitting diode array and a filter capacitor, wherein the LED current and the filter capacitor current are interrupted through a common source i.e. the dual drain field effect transistor (or two equivalent FETs). This turns the LEDs off nearly instantly, turns a switching power converter off and preserves the ripple filtering effects of the filter capacitor.

Abstract: A LED retrofit lamp for replacement of fluorescent lamp or tube driven by fluorescent ballast is provided. The retrofit lamp is compatible with the fluorescent ballast that requires the presence of a barrier for striking an arc voltage. The present invention provides a strike barrier—a controllable barrier that does not allow current conduction until a threshold voltage is reached. When a current above the threshold voltage passes through the strike barrier, the circuit latches and allows conduction at normal voltage. The present invention also provides a circuit that replicates the cathode heater resistance of a fluorescent lamp to rapid start and programmed start ballast.

Abstract: A light emitting diode retrofit lamp for replacement of fluorescent lamp or tube driven by fluorescent ballast is provided. The retrofit lamp consists of an enhanced circuit that overcomes the compatibility issues with the fluorescent ballasts. The circuit of the retrofit lamp comprises a deflickerizer circuit that prevents the flicker in the lamp when the lamp operates in the frequency range of 0.1 Hz to 60 Hz. The deflickerizer circuit further provides a method to align frequency with the ballast frequency and maintains phase to avoid low frequency interference.

Abstract: One embodiment of the present invention provides a system that uses power-line phase-cut signaling to change energy usage for one or more devices that share a common power signal. During operation, the system receives a request to change power usage. In response to the request, the system inserts a phase-cut notch into the common power signal. A device that is located downstream from the inserted phase-cut notch detects this notch in the common power signal, and in response triggers a power-state change. For instance, the device may trigger a reduced-power state when it detects a phase-cut notch.
