Abstract
A working machine includes a machine body, a boom including a proximal end swingably coupled to the machine body, an arm coupled to a distal end of the boom swingably in arm-crowd and arm-dump directions, a working lamp on the boom, and an illumination controller to control the working lamp. The working lamp includes first and second light sources. The optical axis of the first light source is oriented more to the distal end of the boom than that of the second light source is, and the optical axis of the second light source is oriented more to the proximal end of the boom than that of the first light source is. The illumination controller is configured or programmed to, when the arm is within a crowd range, control illuminance of the first light source such that the illuminance is lower than when the arm is within a dump range.
