Abstract: In this paper, a new method is proposed to test whether the automotive lamp's light pattern or shape satisfies the ECE or SAE regulation at about 3-5 m distance instead of the 25 m distances. From the simulation results, we can draw functions that can describe the correlation between the light source flux and the distance from the receiver plane to the light source. By this method, we can easily test the satisfaction of the light pattern or shape with the regulation of ECE or SAE or National Standard of China in Automobile Lamp test. By this method, an economically efficient method may be provided for our test before the lamps' formal test in the specified testing field.
