The distance from the bottom edge of the reflector to substrate is 1.75 inches for our E-175 or 3.5 inches for our E-350. 10 foot sections available upon requestĮlliptical aluminum reflectors provide a line source where one focal point is at the center of the UV lamp, the other focal point is at the surface of the curing substrate. For this reason, only two of our four profiles come with provisions to accommodate reflective inserts.įour standard styles are available, two elliptical and two parabolic diffusers.ħ" Parabolic Reflector comes standard in 5 foot long sections. Even in these cases, our UV reflector extrusions are very cost effective and tend to be less expensive than a new UV reflective liner. Expensive UV reflector liners or reflector sheets are not required however, these reflector sheets may be considered in extremely messy environments where ink or varnish spatter tends to degrade the reflector surface. This high UV reflectance is approximately 90% and unlike other aluminum, this special grade resists tarnishing and corrosion. The inside surface is highly polished to yield an efficient transfer of UV energy from the uv bulb to the curing substrate. Our extruded reflectors are made of specially processed 6061-grade aluminum. For higher power applications it is best to enclose the reflector in a housing, using forced air-cooling to draw air from both ends to create an end cooled reflector assembly, or a center hole on the top of the housing to create a center cooled reflector assembly. Heat from the lamp is absorbed by the aluminum reflector and dissipated into the fin structure opposite the reflective face. Medium pressure lamp power rating from 100 to 600 watts per inch are commonly used. These profiles are time tested, proven designs, to focus UV light from medium pressure mercury and metal additive lamps on to a curing substrate. Our highly polished Aluminum reflector extrusions allow engineers to cost effectively build their own UV curing system without investing in expensive extrusion dies, long lead times, and minimum draw charges.
