Abstract: An adaptive system for controlling the dimming of a light monitors area occupancy as detected by a sensor over successive similar time intervals. The usage is averaged and used to predictively control the brightness of the illumination of the area at corresponding time interval without relying on the sensor to trigger the illumination on a piecemeal basis. The degree of illumination adapts to the statistical average of the number of users in the area over time in the time intervals of interest.

Abstract: A solar-powered airfield light provides high angle light up to about 90°. A solar panel is mounted atop the enclosure but does not overlie a curved transparent shoulder extending upward from the transparent generally cylindrical side walls of the enclosure. An optical element within the enclosure surrounds an LED light source so as to direct light emanating from the LED in two preferential beams, one directed to the shoulder and the other directed to the side walls. A portion of the light impinging on the curved shoulder is redirected to high angles to comply with high angle light requirements for airfield lights.

Abstract: An area lighting system is composed of a plurality of lighting elements that are responsive to the movement and progression of a user through the area. Each lighting element comprises at least one light, means for powering the lighting element, a processor, communication means and is associated with a motion sensor. Detection of a user is communicated to other lighting elements that provide an appropriate level of illumination depending on the distance from the user. The lighting elements are substantially self-configurable and may be set for either a radial proximity lighting protocol or a path network lighting protocol.

Abstract: A network of lighting elements controlled by a control system, in which the control system receives and analyzes operating conditions from the lighting elements in the network, from which it can determine whether any lighting elements are operating at unacceptable levels. The analysis is carried out by averaging the values received from the lighting elements to determine a baseline value and determining whether any deviate from the baseline value by more than a pre-determined amount. Alternatively, the analysis may be done by finding the distribution of the values and mode value, and determining whether any individual values are outside an acceptable distribution.

Abstract: A system for wirelessly controlling marker lights comprising a remote controller comprising a transmitter and one or more marker lights. Each of the marker lights comprise a receiver and processing means, and each of the marker lights have a configuration mode in which the processing means is adapted to cause the receiver to wirelessly receive data from the transmitter. This data comprises one or more group identifiers to assign one or more groups to the marker light. In addition, the processing means of each of the marker lights is adapted to cause the receiver to wirelessly receive one or more commands from the transmitter for controlling the operation of the marker light. The processing means is adapted to carry out the command when the commands comprise the same one or more group identifiers that correspond to the one or more groups to which the marker light was assigned.
