Abstract:
The reflection characteristics of different road surfaces have been studied in accordance with the spectral distribution of high pressure sodium and metal-halide lamps with power of 70W, 150W, 250W and 400W. The lens transmittance of the luminous flux for people at the age of 25 and 60 has also been determined. Determined by the quantity is the spectral efficiency of sodium and metal-halide lamps.
