A durable, reliable street lighting luminaire. A dual chamber die-cast aluminum housing. The excellent thermal parameters of this product were achieved thanks to its special construction that physically separates the optical chamber from the chamber with the electrical equipment. The streamlined shape and the lack of an external heat sink prevent leaves and other debris from collecting on top of the luminaire.Tool-free access to the chamber with the electrical equipment using a clamp. The cover bracket prevents accidental closing of the geartray. Tool-free replacement of the power supply system is possible thanks to the use of a removable plastic panel. When the cover is opened, power is disconnected from the power supply system by a special disconnector, ensuring safe maintenance. The luminaire is equipped with a universal mounting bracket that makes it suitable for mounting directly on a pole or on an extension arm. The inclination angle can be adjusted within a range between -10° to + 10°. The optics consist of a panel with lenses that emit a homogenous photometric solid. In the event of failure of a single or several LEDs, the photometry of the fixture does not change, only the luminous flux of the luminaire is reduced. The special construction of the optical chamber helps limit light pollution in the upper half-space above the luminaire. A special breather drains condensed water vapor and regulates the pressure in the luminaire. Additional overvoltage protection is available up to 10 kV. The surface of the side of the luminaire is smaller than 0.038 m² and limits wind pressure power. Four light distribution variants available: classic, with a wide range of applications; wide, for applications with large distances between luminaires; 2 asymmetrical variants, specifically for pedestrian crossings. Operation in the CLO system possible – smooth energy consumption regulation to maintain a constant light output value.
