International ClassA61C 005/00AbstractA portable, high power arc lamp system for composite curing and tooth whitening applications utilizes battery cells to power a lamp, such as a short-arc xenon lamp. The use of battery power allows for a high power system without the need for costly components required if ac power were used. Battery power is acceptable for low duty cycle applications such as composite curing and tooth whitening. The batteries may be recharged using either standard 110 V or 220 V house current and a charging circuit is included to charge the batteries. An elliptical reflector is used to direct the light from the xenon lamp to a flexible light guide. The system of the present invention is particularly suited to the curing of dental composites and tooth whitening procedures. Significantly improved methods of curing and whitening may be realized through the use of a high power light source of the present invention.Other References
