In embodiments of the present invention, a method and system is provided for commissioning improved intelligent, LED-based lighting systems. The LED based lighting systems may include fixtures with one or more LED light bars, integrated sensors, onboard intelligence to send and receive signals and control the LED light bars, and network connectivity to other fixtures.

Lighting fixtures and methods of commissioning lighting fixtures

A presence or an absence of an occupant is detected, and an occupancy sensor signal is generated representative of an active state in which the presence of the occupant is detected, and an inactive state in which the absence of the occupant is detected. An ambient light sensor detects the ambient light level and generates an ambient light sensor signal representative of the ambient light level. Dimmable illumination is generated at a first dimming level, based on the ambient light level, corresponding to the active state and a second dimming level corresponding to the inactive state. A transition delay time between an onset of the inactive state and a transition between the first dimming level and the second dimming level may be controlled. The first dimming level, the second dimming level, and/or the transition delay time may be variably set or controlled locally or via a remote device.

Lighting fixtures and methods of commissioning light fixtures

In embodiments of the present invention, a method and system is provided for designing improved intelligent, LED-based lighting systems. The LED based lighting systems may include fixtures with one or more of rotatable LED light bars, integrated sensors, onboard intelligence to receive signals from the LED light bars and control the LED light bars, and a mesh network connectivity to other fixtures.

An ambient light sensor measures an ambient light level at one point in an illuminated environment, such as a warehouse, office, shop, cold-storage facility, or industrial facility, and provides an indication of the measured ambient light level to a processor. The processor maps the measured ambient light level to an estimated ambient light level at a different point in the illuminated environment from the measured ambient light level (e.g., a 'task height' about three feet from a warehouse floor). The processor may determine the difference between the estimated ambient light level and a desired light level at the task height, and may change the artificial illumination provided by a light fixture to make the actual ambient light level at task height match the desired light level at the task height.

Methods, systems, and apparatus for intelligent lighting

Intelligent lighting systems include lighting fixtures communicatively coupled to processors and memory to provide efficient, highly responsive, and custom-tailored lighting to meet the needs and preferences of a given user or application. A gateway device provides connectivity linking lighting fixtures to the cloud to enhance data collection, analysis, and lighting control. Configuration profiles along with identification sensing provide object-specific and person-specific lighting conditions within intelligent lighting system environments. Configuration, control, monitoring, and reporting related to intelligent lighting systems are simplified with cloud-based and mobile apps compared to legacy lighting system technologies.

Embodiments of the present invention include an occupancy sensing unit configured to monitor an environment illuminated by a lighting fixture. An inventive occupancy sensing unit may include an occupancy sensor to detect radiation indicative of at least one occupancy event in the environment illuminated by the lighting fixture according to sensing parameters. The occupancy sensor can be coupled to a memory that logs sensor data, which represent the occupancy events, provided by the occupancy sensor. A processor coupled to the memory performs an analysis of the sensor data logged in the memory and adjusts the sensing parameters of the occupancy sensor based on the analysis.

Lighting fixtures and methods via a wireless network having a mesh network topology

Digital Control Ready (DCR) is a two-way open standard for controlling and managing next-generation fixtures. A DCR-enabled lighting fixture responds to digital control signals from a separate digital light agent (DLA) instead of analog dimming signals, eliminating the need for digital-to-analog signal conditioning, fixture-to-fixture variations in response, and calibration specific to each fixture. In addition, a DCR-enabled lighting fixture may also report its power consumption, measured light output, measured color temperature, temperature, and/or other operating parameters to the DLA via the same bidirectional data link that carries the digital control signals to the fixture. The DLA processes these signals in a feedback loop to implement more precise lighting control. The DCR-enabled lighting fixture also transforms AC power to DC power and supplies (and measures) DC power to the DLA via a DCR interface. These features enable intelligent, networked DCR lighting systems operate with lower power (energy) consumption, greater flexibility, and simpler installation than other intelligent lighting networks.
