ABSTRACT:
A device for illuminating a tunnel of an underground mine being worked by an excavating machine comprises a lamp housing with a light-transmissive vaulted cover snap-fitted thereto and with a fluorescent tube horizontally disposed inside that cover, the housing being suspended by a resilient mounting from a horizontal flange of a wall member of the machine shielding it from the mine face. The cover penetrates the flange and raises the tube to a level at which its light radiates upward as well as horizontally toward and away from the mine face; a flared peripheral zone of the cover enables the housing to be repressed against the spring force of its mounting by an object passing across the flange so that the top of the housing lies flush with the flange surface.
