The modern luminaires of the SR family are suitable for a wide variety of tasks in technical road lighting. Equipped with state-of-the-art lighting technology and precise optics, they offer outstanding solutions in relation to energy efficiency, luminaire spacing, light quality and service life. Three construction sizes, two optical enclosures (flat cover panel, convex diffuser) and various lamp configurations for differing light distribution characteristics and light output ratios are available. If the luminaire is equipped with a module for instant hot re-ignition then special security and monitoring applications are possible. The SR luminaire versions for security protection, railways, pedestrian crossings and cycle paths are specified in section 4 (luminaires for special applications).
Despite their robust construction and high IP65 protection rating, the SR luminaires are easy to handle: a central rotary catch on the luminaire underside secures the lamp cover and gear tray. The lamp cover can be hinged downwards by rotating the catch through 180 degrees. A further setting unlocks the gear tray with lamp socket and lamp that can also be hinged downwards. This cuts off the power supply; maintenance and control work as well as tool-free gear tray replacement can be carried out without danger. Maintenance of the radial facetted reflector is also practical, the reflector optimally splitting the light point and ensuring wide distribution asymmetric glare-free light: it can be adjusted via simple pushing in the horizontal plane, thus allowing it to be precisely matched to the specific lighting task at hand.
