7 LED Street Lights Characteristics 1. High Illuminance Uniformity = 54~60%, ( Korean standard(ks) = over 40% ) 2. Long life cycle: LED life cycle is over 100,000hours The temperature of LED metal PCB is under 40~45 C under 25 C environment. It leads long life cycles. Electrical circuit (Constant Current Drivers) life cycle is over 100,000hours. Using metal PCB makes it excellent thermal dissipation. The temperature of the metal PCB (Constant Current Drivers) is under 40~45 C under 25 C environment. It leads long life cycles. Using long life cycled solid capacitor gives 100,000hours life cycles. 3. Dimming control function It dims down the luminous intensity for the saving power consumption by internal timer. ( Adjustable by S/W programming ) 4. Optical LED lens Option 1 ( Lens Type = G type) : for the pedestrian road or the park Beam Projection 2 : 1 Option 2 ( Lens Type = S type) : for the automobile road Beam Projection 3 : 1
