Evolution of the Optical System of Tunnel Lighting Fixture( Evolution of Optical System and Optical Analyzing Technology on Changing to LED Light Source)
in late years LED came to be adopted as a lamp for 血 e 血 n 皿 el lighting normally , LED has high ef且ciency , and life is long , 血e LED can reduce elecnicity of the tunnel lighting and can reCluce the lamp exchange work , too . Because the LED is easy to contro 旦 the light , the evolution of the opnical system the tunnel lighting is remarkable , This introduces the the
