Definition of Terms

UV Curing Light Source -

a reflector housing and a power supply furnished with an appropriate bulb (burner)

for generating light energy of required spectra and intensity.

Flood Lamp System -

a set of components arranged to generate, collect, condition, and direct UV radiant

energy to perform curing of engineering adhesives, coatings, and inks in a safe and controlled process. It

includes a lamp housing and power supply and may also include a shutter, workstation, UV enclosure, Dymax

light shield, and accessories.

Lamp -

light source (bulb or burner) generating ultraviolet, visible, or infrared radiant energy from burning

matter stimulated by electrical power. A bulb or burner is usually placed into a reflector to increase light

source efficiency by collecting and directing radiant energy of selected spectra for a specific curing process.

Intensity -

a measure of light energy over the unit of surface area (usually at a specified working distance

from the bottom of a reflector housing) in W/cm

often called in literature "irradiance", i.e. radiant energy arriving at a point on a surface per unit area.

Brightness, also known as Luminance -

(approximately from 400 to 700 nm) and recorded in photometric units. "Intensity" (see below) of visible light

energy is called luminance.

Luminance -

luminous flux (energy of visible light) incident per unit area, and measured in Lx (lux) or

Lumen/cm

Ultraviolet (UV) -

the invisible region of the spectrum just beyond the violet end of the visible region. UV is

divided into three spectral parts:

1. Ultraviolet A (UV-A) - UV of long wavelength from within approximately 400 to 320 nm of the spectral

band (4000 to 3200) - predominately produced by Dymax Flood Lamps.

2. Ultraviolet B (UV-B) - UV of medium wavelength from within approximately 320 to 280 nm - Dymax Flood

Lamps produce some amount of their energy within this bandwidth.

3. Ultraviolet C (UV-C) - UV of short wavelength below 280 nm (we say from 280 to 200 nm) – a large

amount of this energy is present in the sunlight.

Dose -

is irradiance integrated over time, or Irradiance (W/cm

the power that gives rise to the production of energy at the rate of 1-joule (J) per second (s).

As irradiance can be a far more significant factor in the efficiency of curing adhesives and other UV-curable

materials, the dose and spectral response can also be substantial contributors to the quality cure

performance.

OSHA 1910.145:

"Regulation of Accident prevention Signs and Tags" defines the following headers as:

WARNING – is used when there is a hazardous situation that has some probability of severe injury.



CAUTION - is used to indicate a hazardous situation that may result in minor or moderate injury.



NOTICE - is used to convey a message related directly or indirectly to the safety of personnel, or



protection of property.
