First row: From left to right, the first 5 lights are spaced 6 meters apart, covering a 30-meter range; the 6th, 7th, and 8th lights are spaced 10 meters apart, covering a 30-meter range; the 9th light is spaced 14 meters apart, covering a 14-meter range; the 10th light is spaced 15 meters apart, covering a 15-meter range; the middle lights are spaced 18 meters apart (totaling 31 lights), covering a 558-meter range; the spacing on the right side mirrors the left, with 10 lights covering an 89-meter range. The total length is 6×5 + 10×3 + 14×1 + 15×1 + 18×31 + 15×1 + 14×1 + 10×3 + 6×5 = 736 meters, and the total number of lights in the single row is 5 + 3 + 1 + 1 + 31 + 1 + 1 + 3 + 5 = 51 lights.
Second row (from left to right): At the leftmost position-3 meters from the tunnel entrance-a single LED tunnel light is installed; lights 2, 3, 4, and 5 are spaced 6 meters apart, covering a 24-meter span; light 6 is spaced 8 meters apart, covering an 8-meter span; lights 7 and 8 are spaced 10 meters apart, covering a 20-meter span; light 9 is spaced 12 meters apart, covering a 12-meter span; light 10 is spaced 14.5 meters apart, covering a 14.5-meter span; light 11 is spaced 16.5 meters apart, covering a 16.5-meter span; the intermediate LED tunnel lights are installed with 18-meter spacing (30 lights total), covering a 540-meter span; the spacing on the right side mirrors that of the left, with 11 lights covering the corresponding distance. 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 lights in a single row is: 1 + 4 + 1 + 2 + 1 + 1 + 1 + 30 + 1 + 1 + 1 + 2 + 1 + 4 + 1 = 52 lights. A dual-row configuration requires a total of 51 + 52 = 103 lights.
