MICROWAVE POWERED UV SYSTEM PARTS - ELECTRODELESS BULB
DESCRIPTION: 6" 300 WPI (300 WATTS PER INCH)
Microwave bulbs, more commonly know as electrodeless lamps, are a unique type of medium pressure mercury vapor lamp. In this design, the mercury contained in the
quartz sleeve is vaporized by irradiating the lamp with microwave energy rather than passing current between the electrodes. This offers several distinct
advantages over the standard UV electrode lamp:
Much longer lamp life (generally 3 to 5 times a standard electrode lamp)
Higher efficiency light output
Higher intensity light at working surface
The UV microwave bulbs are available 6 (152.4 mm) in length. They are made in the USA by Fusion UV Systems Inc.
Metal Halide doping (adding a metal halide to the contents of a bulb) is used to change the spectral output of these lamps. Spectral outputs of three most popular
electrodeless bulbs are shown in figures: A-C.
The "H" bulb output is most similar to a conventional medium pressure mercury electrode type lamp output. In the "V" bulb, output has been shifted strongly into the
visible region, while "D" bulb has been tailored to exhibit characteristics of both bulbs. The "D" bulb is often used to achieve good cure depth. "H+" bulb
exhibits enhanced emission at shorter wavelengths, effective in promoting surface cure.
