摘要： A cable reel can improve transfer of power and data between a static frame and a cable wound around a rotatable element. The cable reel can use torsional springs to store mechanical energy and also to electrically couple the cable to a node within the static frame. This electrical coupling can be used to pass power. The cable reel can use a data transfer apparatus to transfer data between the frame and the cable. This apparatus may comprise two capacitive plates that together form a capacitor, one connected to the frame and one connected to the rotatable element. Alternatively, this apparatus may comprise an optically isolated zone in which an optical transmitter may communicate data to an optical receiver over free-space optical communications. The data can be transferred without physical contact between the frame and rotatable element, even while the rotatable element may rotate relative to the static frame.

摘要： A LED based lighting apparatus is disclosed. The light engine used in the lighting apparatus may use a multi-layer metal core printed circuit board and have a plurality of LED groups that are independently controllable by a control unit. The power supply input and return paths connected to each LED group may be implemented on different layers to allow a compact footprint that may be used with traditional fluorescent encasements with relatively little modification.

摘要： Control apparatus for controlling an aspect of an apparatus are disclosed. In certain embodiments, the control apparatus comprises a dimmer that includes a variable impedance. In certain embodiments of the invention, the dimmer may be a TRIAC dimmer having a voltage at a gate electrode of the TRIAC that is always below a trigger voltage for the TRIAC such that the TRIAC never turns on and the remaining components within the TRIAC dimmer can be used as discreet components in a larger circuit. In the control apparatus, the dimmer may be coupled to a signal generation circuit that may generate an output signal whose frequency (period) is dictated at least in part by an impedance of the variable impedance. The output signal may be used to control an aspect of an apparatus such as the intensity, color or color temperature for a lighting apparatus.

摘要： Circuits for sensing current levels within an apparatus are disclosed. In specific cases, a constant voltage power supply is used to power an LED lighting apparatus in which there are uncertainties within the forward voltages of the LEDs, which in turn creates uncertainty with respect to the current level flowing through the LEDs. To manage these uncertainties, the current flowing through the LEDs is measured by determining a voltage level across a known resistor and calculating the current level. To prevent the known resistor from causing a significant reduction in the efficiency of the overall light engine, the circuit includes one or more transistors in parallel with the known resistor to reduce the effective resistance in the LED circuit during times that the current is not being sensed.

摘要： The present invention discloses a lighting apparatus that includes a plurality of parallel circuits and a common circuit. The parallel circuits each comprise a switching transistor and a set of LEDs, the sets of LEDs having different characteristics such as different light output wavelengths. In operation, one of the parallel circuits is selected by activating the corresponding switching transistor, thus selecting the respective LEDs to be activated. The common circuit also comprises a set of LEDs, these LEDs being activated no matter which parallel circuit is selected. In various implementations, the lighting apparatus can generate a wide spectrum of light outputs by selectively activating the plurality of parallel circuits within time slots of a duty cycle. In some cases, balancing of loads across the parallel circuits is desired to maintain the appropriate current flowing through the LEDs.

摘要： The present invention is directed to lighting apparatus and methods for controlling lighting apparatus using ambient light levels. A controller within a lighting apparatus is used to activate and deactivate one or more light radiating devices within a duty cycle. In a first stage, the controller uses a light detection apparatus to sample the ambient light level at a plurality of sampling times during which the light radiating devices are deactivated. The light level when the light radiating devices are deactivated is an indication of the ambient light levels within the surrounding area of the lighting apparatus. The sampling times occur in different duty cycles within a survey time period. The controller determines an average for the light levels sampled over the survey time period, thus generating an averaged ambient light level over the survey time period. In a second stage, the controller adjusts an intensity of the light radiating devices based at least partially upon the averaged ambient light level. The controller may generate a target light level using the averaged ambient light level over the survey time period and a desired light level and, over an adjustment time period, incrementally adjust the intensity of the light radiating devices towards the target light level.

摘要： A method for controlling pulse width modulated lighting devices within a lighting apparatus comprising a plurality of sets of lighting devices is disclosed. The method includes setting a counter for a first set of the plurality of sets of lighting devices using a master counter and an activation duration for one or more other sets of the plurality of sets of lighting devices. The method further includes determining an activation time period within a duty cycle for the first set of lighting devices using the counter for the first set of lighting devices and an activation duration for the first set of lighting devices. In some embodiments of the present invention, the lighting devices are light emitting diodes grouped into sets (or banks) and controlled to limit the magnitude and/or quantity of instantaneous current fluctuations in a power supply within the lighting apparatus.
