Top Ventilation kit for 1200/2000 EC (P/N 38300)
The standard Dymax EC Series lamps employ convection cooling. In situations where supplemental cooling is required or
removal of curing vapors from under the lamp/reflector assembly housing is desired, an optional ventilation kit is available.
The kit can either be a fixed metal skirt that fits on the rear or on the top of the lamp/reflector assembly. The top fan skirt
for the 2000/1200 is provided with the purchase of a shutter.
DEFINITION OF TERMS
Flood Lamp System -
Set of components arranged to generate, collect, condition and direct UV radiant energy to
perform curing of engineering adhesives, coatings, and inks within a safe and controlled process. It includes a Lamp
Housing and Power Supply and may also include a Shutter, and Workstation, UV Enclosure, or Dymax
®
Lightshield, and
accessories.
Lamp
- Light source (bulb or burner) generating Ultraviolet, Visible, and Infrared radiant energy from burning matter
stimulated by electrical power conditioned by a proper power supply which is an integral part of a Lamp. A light source is
usually placed into a reflector (of various geometry) to increase light source efficiency by collecting and directing radiant
energy of selected spectra (for a given curing process).
Intensity
- a measure of light energy over the unit of surface area (usually surface at the specified working distance from
the bottom of a reflector housing) in W/cm
2
or mW/cm
2
. For the UV portion of light, this measure is often called in literature
“irradiance”, i.e. radiant energy arriving at a point on a surface per unit area.
Brightness
, also known as
Luminance
- description of energy in the visible region of the spectrum (approximately from
400 to 700 nm) and recorded in photometric units. “
Intensity
” (see below) of visible light energy is called Illuminance.
Illuminance
- luminous flux (energy of visible light) incident per unit area, and measured in
Lx
(lux) or
Lumen/cm
2
.
Ultraviolet (UV)
- The invisible region of the spectrum just beyond the violet end of the visible region. Wavelength ranges
in general from 1.0 to 400 nm. Dymax
®
bulbs (burners) do not radiate energy in deep Ultraviolet; there are very minute
amounts below 220 nm and practically nothing can be sensed below 200 nm. This is due to the use of an ozone blocking
quartz bulb envelope (See Ozone).
Ultraviolet is used beneficially in various fields of industry and medicine. In order to standardize Light Sources used in
medicine, in Copenhagen in 1932, The International Congress on Light recommended dividing the ultraviolet spectrum
into three spectral parts:
1.
Ultraviolet A
(UV-A) - UV of long wavelength from within approximately 400 to 320nm 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 280nm - Dymax Flood Lamps
produce some amount of their energy within this bandwidth.
3.
Ultraviolet C
(UV-C) - UV of short wavelength below 280nm (we say from 280 to 200nm) – a large amount of this
energy is present in the Sunlight.
Dose
- is irradiance integrated over time, or Irradiance (W/cm
2
) x Time (s) = Dose (Joules/cm
2
). Note: Watt is the power
that gives rise to the production of energy at the rate of 1-joule (J) per second (s).
Ozone
- oxidizing agent (O
3
) produced by the action of Ultraviolet radiant energy (below 185 nm) or electrical corona
discharge of oxygen on air.
