Abstract:
A light fixture includes at least one elongated strut and a socket formed on each strut. Each strut includes a first end, a second end, and an arcuate portion extending between the first end and the second end. An axis extends between the first end and the second end. The arcuate portion extending at least partially around the axis. The socket includes a ridge and a surface supporting a first light-emitting element. The surface is recessed relative to the ridge such that the light emitted by the light-emitting element is directed at an acute angle relative to the axis.
Abstract:
Described herein is a system for a luminaire comprising a lighting unit connected to a luminaire power supply. A controller is provided for controlling the operation of a communication unit and a signalling unit in accordance with environmental parameters sensed by a sensor unit, the sensor unit generating an event signal when the environmental parameters exceed a predetermined threshold and a signalling unit providing an alarm.
Abstract:
A light fixture includes a housing defining a recessed cavity. The housing has a top, a first side, and a second side each extending at an angle from a first end of the housing to a second end of the housing, the first end being substantially orthogonal relative to a first plane. One or more lamp units are positioned in the housing to emit light therefrom, wherein the emitted light is prevented from leaving the housing in a direction parallel to the first plane.

Abstract:
An array of outdoor lighting operates mainly in independent mode wherein sensing, communication, and control processes take place between the various lights of the array. Additional communication and control may occur between the array and a control station by means of a master/coordinating node that transmits and receives signals to the control station via call phone and/or satellite. The system may be tied to the internet for dissemination of data and/or data analysis gathered by means of the multiple poles/devices of the array. The independent- array and/or the master-to-station network and communications may be adapted for energy-saving processes; power-receiving from or power-providing to the grid, renewable power production and storage by means of solar panels and/or wind turbines and associated batteries or other storage equipment; and/or to Wi-Fi hot-spots, public safety alarms, information, or advertising to the public or information/data-analysis to customers. Preferred members of the array have solar- panel-powered lights, which may charge batteries and optionally supply energy to an electrical grid. In arrays cooperating with the grid, the grid may optionally charge the batteries of the array during off-peak hours. The preferred lights include LED modules that may be aimed to establish desired light patterns.
Abstract:
An LED lighting fixture (10) includes a support structure (20) having a horizontal cross-dimension (22) and a top structure (30) attached to the support structure (20) and extending outwardly beyond the support structure (20). The top structure (30) has a bottom surface (32) with a peripheral portion (33) surrounding a non-peripheral portion (34). A plurality of LED emitters (12) are positioned on the peripheral portion (33) for emitting light in downward direction substantially outside of the horizontal cross-dimension (22) of the support structure (20).
