Abstract

A lamp with uniform illumination pattern is used for homogeneous illumination an illuminated area and includes at least one light module. The light module includes two light sources respectively having different light intensity and arranged orderly. Two extension cords of two optical axes of the two light sources have one crossover point. The light emitted from the light source with less light intensity illuminates the illuminated area which is closer to the light module, while the light emitted from the light source with greater light intensity illuminates the illuminated area which is farther to the light module. Light emitted from the light source, which is father to the illuminated are, can make up the intensity losses of attenuation since light emitted from the light source which is father to the illuminated area have greater light intensity. As a result, the lamp has uniform illumination pattern.
