摘要： A control device may have a plurality of buttons that may be backlit to multiple levels, such as first, second, and third adjacent buttons positioned in order, and first, second, and third LEDs positioned to illuminate a respective button. The control device may be configured to illuminate the first LED to a first LED illumination intensity to illuminate the respective button to a first surface illumination intensity; illuminate the third LED to a second LED illumination intensity to illuminate the respective button to a second surface illumination intensity; and illuminate the second LED to a third LED illumination intensity to illuminate the respective button to the second surface illumination intensity. The third LED illumination intensity may be less than the second LED illumination intensity, which may be less than the first LED illumination intensity, and the second surface illumination intensity may be less than the first surface illumination intensity.

摘要： A system and method provide fail-safe operation of a lighting system. A lighting level detector is used to obtain a baseline lighting level for a low-intensity light. If the detector measures less than the baseline level when an occupancy sensor determines the space is unoccupied, a high-intensity light is energized and an indication is provided to a user that the low-intensity light has failed. A method provides daylighting operation of a lighting system. An occupancy sensor can have Wi-Fi functionality to enable remote configuration of the sensor. A line voltage occupancy sensor can include an interface with low voltage devices. An occupancy sensor can include an integral interface to enable an external control system to override the sensor's normal logic under emergency conditions. An occupancy sensor can include an active temperature compensation feature. An occupancy sensor can also incorporate an automatically adjustable coverage area.

摘要： Controlling the color temperature of a composite light source including at least one discrete-spectrum light source is disclosed. For example, the color temperature of a composite light source including at least one discrete-spectrum light source may be determined and/or adjusted based on one or more of the ambient color temperature of a space, the actual temperature of the space, the relative brightness of the space, the occupancy of the space, a time clock, a demand response command (e.g., from an electrical utility), the absolute location of the composite light source, the location of the composite light source relative to other light sources, inputs from a camera or other external devices, the operation of appliances or other machines in the vicinity of the composite light source, media content being utilized in the vicinity of the composite light source, and/or other sensor inputs.

摘要： An automated headlight system for vehicles replaces the high and low beam with a continuum of beam patterns, with further variable spatial distribution of intensities and color spectrum. The digital-headlight is comprised of a controller, sensors and multiple, individually-controllable light-sources modified by optical-control elements to form narrow-beams which are then combined to create the overall headlamp beam. Utilizing real-time sensor data regarding beings, objects and vehicles in the way-ahead, as well as optional information on the driver, vehicle and environment, the logical controller dynamically adapts the headlight system's illumination so as to provide vehicle operators with optimal visibility while preventing discomfort-glare from reaching the eyes oncoming traffic or pedestrians.

摘要： An LED arrangement comprising at least one LED, which receives an LED illumination voltage in accordance with a square-wave signal, wherein the brightness of the LED is dependent on the ambient luminosity, which is measured by means of the LED, which is switched in a non-illuminated state as a light sensor. The at least one LED is arranged together with a first and a second transistor in a bridge circuit such that the first transistor applies the LED illumination voltage to the LED in accordance with the square-wave signal, and the second transistor applies a voltage having inverted polarity as the LED illumination voltage to the LED in intervals of the turned-off times of the LED, wherein the duty cycle of the square-wave signal is dependent on the strength of a photocurrent, which flows through the LED when the voltage having inverted polarity is applied thereto.

摘要： A lighting device or system is configured to control of one or more parameters of light output, such as ON/OFF status, intensity when ON, color characteristics and position or orientation of light output (e.g. via a motorized luminaire control). The device or system may have other output capability, e.g. display projection or audio. Sensors or other input devices are responsive to the user. Responsive to user input, sensed activity, and/or acquired information, the device or system, controls a light source in accordance with a lighting control function. Operation of the light source and the lighting control function may be modified based on learning by the device or system.

摘要： A solar or self-powered assembly includes a rechargeable battery and photo voltaic panel and/or wind turbine for supplying a battery charging current. A charge controller processor is controls charging current from the photovoltaic panel and/or wind turbine to maintain the battery in a substantially fully charged state of 80% or more state of charge over daily charge and discharge cycle charging is based on a projected target energy input based on the initial bulk energy charge, the level of discharge required to compensate for charging inefficiencies and the battery capacity factor representative of the projected natural charge in the battery over its lifespan.

摘要： A sensor unit for ascertaining control data for use in a daylight-dependent light-controlling device having an image sensor for acquiring digital image data as well as a controller for analyzing the image data and creating a brightness signal representing the daylight. The controller is designed such that when creating the brightness signal, same gives more weight to those image regions of the image data acquired by the image sensor which are more greatly influenced by the daylight.
