Double ended quartz lamp with end bend control

摘要

A linear double ended lamp can be modified into a number of non-linear arrangements by heating selected regions of the lamp ends to the softening temperature and bending the lamp ends to a desired angular configuration. Preferably, the lamp ends are bent across the sealing foil that is hermetically sealed to the lamp envelope. One or both ends of the lamp can be bent as desired to define a variety of configurations. According to the method of forming the bent double ended lamp, selected regions of the lamp are raised above the softening temperature while the remainder of the lamp is maintained at a lower temperature. Preferably, the lamp ends are bent along an axis offset and parallel to the longitudinal axis of the lamp to prevent accumulation of material.
