Linear lighting apparatus and methods

Linear lighting systems and methods. In one example, two or more lighting elements having an essentially linear or curvilinear shape are coupled together to form a lighting system. Each lighting element includes a group of LEDs arranged so as to illuminate the essentially linear or curvilinear shape of the lighting element. Each element may include LEDs to generate the same color light, and/or LEDs to generate light of different colors. Additionally, each element may include one or more controllers to control the LEDs so as to create a variety of temporal and/or color-oriented lighting effects. The controller(s) may employ one or more of a variety of control techniques to control the LEDs, such as those involving analog control signals or pulse-width modulated (PWM) control signals. The lighting elements of the system may each be configured as a “stand alone” unit working within the system, producing respective lighting effects that may or may not be coordinated with each other. Alternatively, two or more elements of the system may be configured as addressable lighting elements to facilitate coordination of the elements as a networked lighting system. Any of the foregoing linear lighting systems may be used in a variety of interior or exterior, as well as direct or indirect, lighting applications. In one example, such lighting systems are particularly well-suited as replacements or substitutes for neon lighting installations.

Lighting systems and methods of auto-commissioning

A lighting system for areal illumination is disclosed which includes a remote driver and a plurality of fixtures including luminaires, control devices, and/or standalone sensors. The luminaires include a light source whose output light level can be adjusted, a light sensor co-located therewith adapted to measure light received from adjacent fixtures, and a microcontroller capable of transmitting the output of the light sensor over wires to the remote driver. The remote driver is capable of bidirectional communication with the luminaires and provides independently controllable power for the light sources of the luminaires. A method of commissioning a lighting system is also disclosed which includes installing a plurality of luminaires above the area to be illuminated, causing a light source co-located with each luminaire to emit a signal, detecting the signal at light sensors co-located with each luminaire, converting the signals obtained by the light sensors into distance measurements between luminaires, creating a map recording the relative location of luminaires, and assigning luminaires to groups based on their relative locations in the map. A movable orb region large enough to containing a plurality of luminaires can also be defined and the light levels of individual luminaires can be set according to a defined mathematical function of their location within the orb region, where the defined mathematical function sets light levels which vary from the center to the periphery of said orb region.
