HAND HELD, HIGH POWER UV LAMP

摘要

A UV curing lamp (18) has variable resistive ballast (Fig. 6A) provided by at least one resistance alloy wire. The variable resistance ballast defines the lamp's maximum operating power consistent with the power supply. The wire in combination with a fan also doubles as thermal ballast provided by air flowing across the wire onto the UV lamp. A detachable reflector (21) in a generally parabolic cylinder shape directs light from the lamp located on the reflector's focal axis. The curing lamp with resistive ballast can be in the form of a handheld unit (11) or as a floor unit (Fig. 8) with rotating lamps within the housing.
