Abstract
A lighting fixture having an insulation shield mounted thereto for maintaining surrounding insulation a desired spacing from at least portions of the fixture to increase permissible lamp wattages in an insulation contact application, the shield is preferably formed of a polymeric material molded with openings to permit access to portions of the fixture such as a junction box. The insulation shield is particularly useful with downlighting fixtures installable immediately above ceiling openings, such fixtures typically being mounted to structural joists or to suspended ceilings, and especially downlighting fixtures where lighting performance is to be improved through use of higher wattage lamping. The insulation shield acts to provide a desired volume of air around the fixture in order to more effectively dissipate heat generated by the higher wattage lamping.
