Lighting devices are taught for machine tools. The lighting devices may include one or more light emitters controlled by an electric circuit, which can be connected via one or more conductors to the inner circuit of an electric machine tool. The electric circuit may comprise at least one photometer and a controller that automatically controls the illumination level of the light emitters in response to the ambient light intensity detected by the photometer. The present invention also relates to machine tools comprising such lighting devices.
