Ultraviolet
(UV) radiation causes many useful chemical reactions, with purposes far beyond
giving a suntan. UV light, emitted
within a specific range of wavelength, can cure and instantly dry inks, glues,
adhesives and various coatings providing a smooth and hardened finish. The proper UV lamps must be used,
manufactured with experience and knowledge of the various functions provided by
the different wavelengths of UV emissions.
UV
curing can be used for curing surfaces in several industrial and manufacturing
processes. High pressure lamps, also
referred to as Metal Halide lamps, are used in many industries such as
automotive, aerospace, advertising, medical, food and beverage, cosmetics, and
many others, for curing various surfaces quickly and effectively.
UVA / UVB / UVC
– Various UV Wavelengths are Used for
Specific Purposes
UV
radiation is emitted at different wavelengths, measured in nanometers, which
means a billionth of a meter, and is the common measurement for wavelengths of
electromagnetic radiation. Visible
light is within the range of 400 to 700 nanometers.
Ultraviolet
light can be broken into three different categories, UVA, UVB and UVC, ranging
between 200 to 400 nm. UVA light has a wavelength
with ranges between 315 - 400 nm, while UVB falls into the mid-range of 280 –
315 nm and causes most sunburn, and UVC makes up the shorter wavelengths
ranging from 200 – 280 nm.
UVB
and UVC light are most commonly used for sterilization and purification purposes in medical and environmental applications, with variations available
in low pressure (LP) amalgam lamps, medium pressure (MPUV), and high pressure output
lamps.
LightSources is the Expert on High Pressure UV
Lamps
High
pressure UV curing lamps emit shorter wavelengths peaking at 254nm, and raging
all the way to 365nm. The typical high
pressure lamp emits radiation within this range, although the shorter waves at
254nm are ideal for germicidal functions, including water, air and surface sterilization.
High
pressure UV lamps can also be used in higher wavelengths ranging from 385nm to
417nm, and are used in reprographics, providing superior print quality for long
lasting durable results. The engineers
at LightSources are not limited to the typical manufacturing standards; we can
alter the spectral output with additive compounds, harnessing additional peaks
of UV radiation. We are experienced at
using gallium-iodide at 400 – 450nm, and iron-iodide for desired ranges between
350 – 400nm. Other variations of
additives are available upon request, depending on your application and desired
results.
LightSources and our affiliated companies
represent the leading high-tech designers and manufacturers in the lamp
industry today. Our products are used
world-wide in a multitude of applications and industries such as our UV polymer
curing lamps that offer patent-protected, OEM-oriented solutions. Please contact us to learn more about our
