Date Announced: 03 Nov 2009 On 11th Sep,2009, Chongqing Highway Tunnel Testing Center of State Authority tested the LED Tunnel lamp of Jishan Optoelectronics which the JS570 series 50—140W LED tunnel lights completely through the national testing certification.By one-way two-line, speed 80km/h, the Group of Experts tested the entrance section, light and dark transition section for the 140W LED Tunnel Lamp of Jishan Optoelectronics, the test results show that:1.Entrance section: Average luminance 125.13cd/ m2, more than 10% higher than the national standard; The overall uniformity 0.893 which is 2.23 times the national standard; Longitudinal uniformity 0.997 which is increased 43% than the national standard.2.Light transition section: Average luminance 40.73cd/m2, more than 11% higher than the national standard; The overall uniformity 0.88 which is 2.2 times the national standard; Longitudinal uniformity 0.992 which is increased 65% than the national standard.3.Dark transition section: Arranged the lamps with bilateral symmetry by the space of 6m. Average luminance 13.54cd/m2, more than 10% higher than the national standard; The overall uniformity 0.831 which is 2.1 times the national standard; Longitudinal uniformity 0.981 which is increased 96% than the national standard.Total Power 150W for Jishan Optoelectronics JS570 Series LED 140W, used in the same environment, its brightness and uniformity are greater than 250W SON(high pressure sodium) and MH(metal halide) lighting effects, with energy- saving for 50%.
