Alliance Optotek showcases outdoor lighting fixture

June 26, 2009
Date Announced: 26 Jun 2009 Applications:Outdoor lighting, for example alley lighting, park lighting, solar lighting, street lighting. Features:(1) OpticalBatwing beam patterns design with IESNA classification of type II, short and cut-off. The pole pitch is up to 4 mounting height with uniform illuminance distribution. (2) PowerSwitching mode and multiple channel constant current design to drive the individual LEDs series connected circuit to ensure LED constant current loading. Over-heat and –voltage protection designs, self-thermal compensation ensured LED life. DC to DC power efficiency can reach 89%. (3) Thermal Optimal thermal design of the luminaire and surface temperature to achieve 55°C at 30°C ambient and still air condition, 2°C temperature variation on sink base and LED junction temperature is controlled below 70°C. Overheat protection design, the LED current self- adjusted as sink base temperature reaches 70°C.(4) Luminaire efficacy Super high brightness, the total luminaire efficacy achieves 74.5 lm/W (not including AC to DC circuit power consumption). LED Light Source: Nichia 083(BT) x 24 eaBeam Angle: Type II, Short, Cut offColor Temp.: 5200±400 / 3000±300KInput Voltage: 12Vdc or 24VdcPower Consumption: 26WOperation Temp: -30°C~50°CIP Rating: IP65Net Weight: 2.1kgOutput Lumens(Typ.): 1789/1430
