Metal Halide Lamps
In addition to a broad range of medium pressure mercury arc lamps, Primarc is continuously developing a series of spectrally enhanced metal halide versions. Metal halide lamps are mercury vapour lamps with metal halide additives which create specific wavelengths of ultraviolet radiation to precision-match the photo-initiator being cured. The addition of metal halides creates a shift in the spectral output of a standard lamp, producing longer wavelengths. These longer wavelengths enable a greater depth of cure to be achieved, making them particularly useful in the curing of pigmented and thicker coatings. Metal halide lamps are increasingly used in the printing industry, as well as in a wide range of industrial manufacturing applications such as the production of printed circuit boards, electronic components, fibre optic cables, CDs/DVDs, and wood products.
Since 1970 Primarc has played a leading role in UV lamp development. The Primarc team is dedicated to providing design and manufacturing support to end-users and OEMs worldwide. Our R&D department works constantly with a range of companies to develop new applications for UV curing and improve existing products. With over 30 years experience in UV technology, Primarc is one of the world’s longest serving manufacturers of UV curing lamps. During this time, our technical expertise, manufacturing processes, and repeatability of lamp performance have reached a standard that has become the benchmark across the globe.
Primarc® UV curing lamps are manufactured in lengths from 2cm to more than 300cm and currently at power outputs of up to 500 Watts per cm (1270 Watts per inch). To ensure maximum efficiency of any UV lamp, a Primarc Transformer Control System is always recommended. A separate information sheet covering these is available on request. Primarc have a complete range of their own originally designed lamps, or if required, lamps can be designed to meet customers’ specific requirements.
Metal Halide Options
A mercury-vapour lamp has the spectral output shown in Fig. 1.
For applications where a different wavelength of UV is required, the spectral output of a standard lamp can be shifted to different wavelengths by utilizing energy transfer from the mercury atoms within the arc to another material added during manufacture (Metal Halides). The spectra of two typical spectrally-enhanced lamps are shown in Figures 2 and 3.
While Primarc manufactures equivalent lamps to makes such as Hanovia, Heraeus, BLV, BVS, Eye, Superior Quartz, Mazda, Philips, Sylvania, Toshiba, Ushio, Voltarc, etc., it is important to identify the specific lamp for your UV drying system. Please complete the Lamp Identification Sheet so that an equivalent lamp can be identified.
List of Primarc equivalent lamps is ever growing. If in the list to download you don’t see your lamp, please contact us or better send us the “Lamp Identification Form” carefully compiled.
