Lighting Solution of LED tunnel light
Unlike usual road lighting, tunnel lighting has its unique particularity, especially in the presentation of the safety of tunnel lighting system.
Bad environment, such as vehicle exhaust, noise, vibration, pure air, etchant gas, will cause the specialty of tunnel lighting. For a safe and warm lighting circumstance to passing vehicle and passengers, we will discuss the design thought and method with analysis.
Use Spark LED tunnel light SPT-56 F(Square):
LEDs we use now for tunnel light have reached 114-122lm/W,with the electrical voltage of 3.2V, we still apply 320hA for power supply for LED tunnel light, so the practical working power is 1.024W, the total power of 56pcs is 61.6W, Upon 86% of power efficiency, the total power is 72.6W. Within 736meters tunnel, there will be a need of 103 pcs LED tunnel lights, which total power is 103*71.3=7374.8W. Calculated with 24hrs per day as working time, the total power consumption will be 215.3Kwh per day, annual power consumption will be 71950 Kwh.
56W LED tunnel lights project
Now the practical length is 736 meters. Base on the HPS install plan, lighting area of the high power LED tunnel light will be separated into three luminance area. From entrance to 30 meters distance is high bright area, the illumination reaches 80Lux; From 30 meters to 60 meters is medium bright area, the illumination reaches 50Lux; From 60 meters to 96 meters is transition area, the illumination reaches 40Lux. The middle of LED tunnel light is low bright area; the illumination only requires 30Lux. When the night comes, the bright lights turn-off, the whole tunnel become low bright area, the illumination should be around 30Lux.
When adopting light with LED tunnel light, 103 pcs LED tunnel lights will be applied in the whole tunnel. 40 pcs tunnel lights near the entrance and exit of tunnel will be controlled intelligently, used to adjust the brightness. 63pcs in the middle will work with full-mode all the year around. Total amount will be 103pcs, 7pcs more than previous solution.
