Abstract: A lighting system and method for controlling illumination of the same upon detection of a user in at least one of a first detection area and a second detection area. The lighting system can include a lighting fixture having one or more lighting sources and at least two sensors associated with separate detection areas. Each sensor can send a signal to a controller associated with the lighting fixture, and the controller can be configured to vary the illumination of one or more of the lighting sources depending on the each sensor's detection area. The present subject matter facilitates energy savings since areas away from an occupied area are not illuminated. Communication between neighboring lighting fixtures is not required since each lighting fixture can detect the presence of a user in an area proximate an adjacent lighting fixture in order to trigger illumination of the lighting fixture.

Abstract: A lighting system includes a plurality of fixtures, wherein each fixture includes a plurality of fluorescent lamps. A dimming ballast is operatively coupled to each fixture, each dimming ballast receives power from an outside source that is delivered to the fluorescent lamps within each corresponding fixture. A control module communicates with each dimming ballast, the control module receives a lighting level from an outside source, determines the most power efficient lighting solution and outputs a control signal to each dimming ballast related to the light output level of each lamp within each fixture.

Abstract: The present subject matter is directed to a lighting control system and method. Motion or occupancy sensors are used to determine when a lighting fixture and/or a nearby lighting fixture should be activated. A controller associated with each lighting fixture switches its lighting fixture on and triggers a communications circuit to generate and send a signal to nearby lighting fixtures when a user is detected. Each lighting fixture also has a signal receiver to receive signals from any nearby lighting fixtures that are configured to communicate with it via a communication circuit. The present subject matter allows for a significant amount of energy to be saved as remote areas away from an occupied area do not have to be illuminated. Meanwhile, the user is still provided with a comfortable level of lighting in and near the occupied area.

Abstract: Disclosed herein are mercury free ceramic metal halide high intensity discharge lamps of specified arc tube geometry and composition of ionizable fill. Embodiments herein generally employ a discharge vessel formed of a ceramic material having an aspect ratio satisfied by 1<ITL/ID<4.5 where ITL is the inner total length of the discharge vessel and ID is the inner diameter of the discharge vessel. The ionizable fill typically comprises xenon at a cold fill pressure of from about 3 to about 15 bar, and a halide component comprising sodium halide, thallium halide and/or indium halide, and at least one rare earth halide. Disclosed advantages may include betterment in both lumen run-up and color shift upon dimming, as compared to mercury-containing CMH HID lamps.
