Abstract

To achieve a reduction in power consumption during work and to enable appropriate illumination of a work area. A working machine includes a machine body (2), a boom (14) including a proximal end coupled to the machine body such that the boom is swingable up and down, an arm (15) coupled to a distal end of the boom such that the arm is swingable in an arm-crowd direction which is a direction toward the boom and an arm-dump direction which is a direction away from the boom, a working tool (16) attached to a distal end of the arm, a working lamp (20) provided at the boom to illuminate a work area around the boom, and an illumination controller (44) to control an illumination operation of the working lamp. The working lamp includes a first light source (25) and a second light source (26) with different optical axis directions from each other. The optical axis direction (N1) of the first light source is oriented more to the distal end of the boom than the optical axis direction of the second light source is to the distal end of the boom, and the optical axis direction (N2) of the second light source is oriented more to the proximal end of the boom than the optical axis direction of the first light source is to the proximal end of the boom. The illumination controller is configured or programmed to, when the arm is within a crowd range (P2), perform a first control to control an illuminance of the first light source such that the illuminance of the first light source is lower than when the arm is within a dump range (P3), the crowd range being a portion of a swinging range of the arm that is located in the arm-crowd direction, the dump range being another portion of the swinging range that is located downstream of the crowd range in the arm-dump direction.
