摘要:
A method for performing self-diagnosis in a light fixture. The method includes receiving data corresponding to a plurality of environmental conditions from one or more sensors. The one or more sensors are positioned in a sensor cavity of a light fixture wherein a plurality of conduits provide a sealed path between a plurality of LED modules of the light fixture and the sensor cavity such that the LED modules, the conduits and the sensor cavity exhibit a plurality of environmental conditions. The method also includes analyzing the data to determine if at least one of the plurality of environmental conditions has undergone one or more of the following changes: a change so that a value of the at least one environmental condition exceeds a threshold level, a threshold change compared to a corresponding constant level, or a rate of change that is greater than a threshold value.

A lighting device includes one or more LED modules, each of which includes a group of LED sets positioned on a substrate. Each LED set includes two or more sections, optionally under a single lens. The sections are individually controlled by a controller of the lighting device or an external controller. The beam spread, beam shape, or both of the light emitted by the device may be controlled by selectively activating the sections of each LED set.
摘要:
A system of networked lighting devices includes a central controller and a group of lighting devices. The central controller includes a processor, first and second communication interfaces, various lighting devices and a communication link. The first communication interface includes input ports and a multiplexer configured to receive signals from the input ports and combine the received signals into a multiplexed signal. The second communication interface includes one or more antennas and is configured to receive the multiplexed signal from the multiplexer and transmit the multiplexed signal via the antenna(s). Each lighting device includes a fixture controller, one or more lighting modules, and a communication interface. The communication link transmits the multiplexed signal between one or more of the lighting devices and at least one of the communication interfaces of the central controller.
摘要:
A lighting system includes a group of light emitting diode (LED) illumination devices. A controller may identify a set of the illumination devices that correspond to a zone, and to generate commands to cause the device drivers for each of the identified illumination devices to control its corresponding illumination device so that a specified color temperature, illuminance level, or both of light will be received at a location in the zone. A method for calibrating such a system is also disclosed. A user interface allows a user to select a scene after the calibration is complete.
摘要:
A lighting device includes a light emitting diode (LED) structure having LEDs, a housing, and a power supply. The housing receives and secures the LED structure, and includes a body portion that comprises a heat sink for the LED structure, and a shroud that at least partially shields the LED structure. The heat sink comprises various fins that extend away from the LED module in a direction that is perpendicular to a width of the LED structure.
摘要:
A light fixture includes one or more of light emitting diode (LED) modules. Each of the LED modules may include a substrate holding a plurality of LEDs, and a printed circuit board connected to the plurality of LEDs. Each of the LED modules may also include a flexible lens cover including a plurality of lenses, each positioned to be located over one of the LEDs. The flexible lens cover may include a side sealing structure configured to interface with the substrate and seal the lens cover to the substrate.
摘要:
A lighting control system includes a control card for an illumination device. The control card receives an input signal from a controller electronic device, identifies a type of the illumination device, and uses the identified type to identify an output signal protocol corresponding to the illumination device. If the input signal uses a protocol that differs from that of the output signal protocol, the control card will convert the input signal to the output signal protocol. The controller device may be programmed to enable a user to display and/or control various parameters of various lighting devices.
摘要:
A light fixture includes a housing comprising a body portion with an opening at a first end, a power supply at an opposing second end, and a heat sink comprising a plurality of fins between the opening and the power supply. A mating surface is positioned proximate to the opening. The mating surface includes a set of landing pad areas and a set of open areas. The fixture also includes a set of light emitting diode (LED) modules, each of which is positioned in the opening and secured to a landing pad area of the mating surface. The LED modules are arranged so that the plurality of open areas remain open to the atmosphere and provide an air path to and from the heat sink.
