Abstract: There is provided a lighting device consisting of two or more light emitting diodes (LEDs) which are configured to provide an elliptical pattern of light to illuminate a barrier and/or adjacent areas. The lighting device may be part of a barrier protection apparatus and system. The apparatus includes the lighting device, a processing device, a wireless communications subsystem, and one or more sensors configured to detect a possible intrusion of the barrier. Each apparatus may also communicate wirelessly with neighbouring apparatuses and/or a central controller. The data from one or more sensors may be received and analyzed by each apparatus and/or by the central controller to determine whether an alarm condition has occurred indicating a possible intrusion. Each apparatus and/or the central controller is configured to control the lighting device based on the received sensor data.
