# Italian tunnel light wiring and location diagram

After adopting the tunnel LED transformation, a total of 40 lamps at the entrance and exit of the tunnel will adopt intelligent control of its brightness to control its brightness. A total of 63 lamps will be used for all-round power work. The total number of lamps is 103???, before The design should be 7 more. The specific method is that a light-sensing controller is installed in the entrance and exit of the tunnel to collect optical signals, and the optical signal directly controls the brightness of the 40-inch tunnel light of the tunnel entrance and exit. When the light is good during the day, the whole power is used, and the half power is used at night. The brightness varies with the brightness of the external environment. The controller does not consume power. When the light outside the tunnel is good during the daytime, the light at the tunnel port will work at full power. The brightness at this time basically meets the requirements of 80, 50, 30 Lux. After half-power operation of the tunnel portlight at night, the brightness of the hole is about 40 Lux, and the tunnel is still 30 Lux. If you don't need the brightness to change with the external environment, you can set the fixed time and change its brightness. Schematic diagram of installation and wiring of tunnel lights:

The second row: from left to right: at the leftmost position of the 3 m spacing of the tunnel entrance, a tunnel is installed at the tunnel entrance; the installation distance of the 2nd, 3rd, 4th, and 5th lamps is 6 meters, and the illumination is 24 Meter range; the installation distance of the 6th lamp is 8 meters, the range of 8 meters; the installation distance of the 7th and 8th lamps is 10 meters, the range of 20 meters; the installation distance of the 9th lamp is 12 meters, irradiation 12 The range of meters; the installation distance of the 10th lamp is 14.5 meters, the range of 14.5 meters; the installation distance of the 11th lamp is 16.5 meters, the range of 16.5 meters; the middle lamp is installed at a distance of 18 meters / ,, a total of 30 , the illumination range is 540 meters; the installation pitch on the right side is the same as the left side, a total of 11 inches, the illumination range is meters; the total length is: 3+6*4+8+10*2+12+14.5+16.5+18*30 +16.5+14.5+12+10*2+8+6*4+3=736 meters, the total number of single row lights is: 1+4+1+2+1+1+1+30+1+1+1+ 2+1+4+1=52???

JL-066-08-1 tunnel light, the LED we have used has been increased to 1W 90~105Lm, the current voltage is 3.2V, we still use 320hA power supply, so the actual working power of 1 LED is 1.024W, The total power of 66 light sources is 67.6W, and our power conversion efficiency is 86%, so the total power is 78.6W, the total length of the 736m tunnel is 103???, and the total power is 103 78.6=8095.8W.

Schematic diagram of the installation position of the tunnel light:

The tunnel body is installed as follows:

The first row: from left to right: the installation distance of the first 5 lamps is 6 meters, and the range is 30 meters; the installation distance of the 6th, 7th, and 8th lamps is 10 meters, and the range is 30 meters; The installation distance of the lamp is 14 meters and the range is 14 meters; the installation distance of the 10th lamp is 15 meters, and the range is 15 meters; the middle lamp is installed at a distance of 18 meters/inch, 31 ???, and the range of 558 meters; The installation spacing on the right side is the same as the left side, a total of 10 inches, the illumination range is 89 meters; the total length is: 6*5+10*3+14*1+15*1+18*31+15*1+14* 1+10*3+6*5=736 meters, the total number of single row lights is: 5+3+1+1+31+1+1+3+5=51???.

Calculated by working 24 hours a day, the total power consumption is about 194.3 kWh, and the year is about 70,920 kWh.

Since I did not receive the installation diagram of the original tunnel light before, I always thought that the tunnel length was 700 meters to design, and now the actual length is 736 meters. For this reason, I have made another adjustment, and considering the vicinity of the hole. Tunnel lights are intelligently controlled by their brightness rather than the direct nighttime closure of conventional sodium lamps, so the overall lamp mounting density must be re-adjusted to the needs of the floor's brightness. The installation layout of the original sodium lamp will form three brightness areas when the glare lamp is turned on. The high brightness area is 0~30 meters from the hole, the brightness is 80Lux, the medium brightness area is 30~60 meters, and the brightness is about 50Lux. 60~96 meters for the transition area is about 40Lux, the middle area of a€?a€?the tunnel is low-luminance area, the brightness is about 30Lux, when the night light is off, the whole tunnel is all low-brightness area, the brightness is about 30Lux.

A total of 51+52=103 lamps are required for the double row.
