The paper presents an original solution for intelligent street lighting, power saving by tele-management. The focus is on lighting systems using luminaries equipped with high pressure sodium lamps. The paper details the results of measurements of a wireless controlled supplementary ballast for the dimming function for HID lamps. An efficiency analysis of the switched supplementary ballast for dimming function is presented. An innovative ISM band wireless network protocol for tele-management is also presented. The paper outlines the results of the preliminary tests of the novel protocol with minimal interference with ISM band wireless infrastructure. The basic operation protocol of the proposed wireless network is introduced with emphasis on minimal ISM band interference. An original node identification scheme is also proposed for geographical organization and visualization of the network. In conclusions the future further development of the proposed intelligent lighting solution are outlined.
