ABSTRACT:
A discharge lamp includes a bulb in which a pair of electrodes are installed and mercury and a rear gas are sealed. A heater unit is tightly attached to the outer surface of the bulb by a heat-shrinkable tube fitted over the bulb. The heater unit includes a thin flexible heater for heating the bulb to promote the evaporation of the mercury, and a pair of film members fixed on both sides of the heater so as to reinforce the heater.
