Heat insulating unit to be attached to inner surface of reflecting area of heater or lamp, assembled of several layers

摘要

The inner front area of a heater or the reflector area of a lamp is divided from the main system by a convex insulating unit assembled of several layers. An insulating sheet (4) guided in lateral grooves is positioned at a distance to the rear surface of the reflector (6), forming a fist air chamber (5). A second air chamber (3) is created between the rear surface of the insulating sheet (4) and the front surface of the housing (1).
