ABSTRACT:
This portable lighting fixture comprises a lamp housing containing a lamp and a reflector that projects light from the lamp through an opening in the front face of the housing. A protective grill on the housing registers with the front-face opening in a location spaced from the opening. Normally located beneath the housing is a base that normally supports the housing. The grill has an outer periphery that appears rounded when viewed from a horizontal reference plane located above the housing when the housing is in its normal location atop the base. Tip-over of the fixture onto a horizontal surface that causes the central peripheral portion of the grill to fall against the horizontal surface results in the fixture rolling over in a lateral direction on the rounded grill following initial contact between the central peripheral portion of the grill and the horizontal surface. This roll-over action causes heat that is emitted through the front-face opening of the fixture to be directed via a path that is oriented to produce reduced heating of the support surface under these conditions.
