Lamp Irradiator Assemblies

Our proven LIA's (Lamp Irradiator Assemblies) provide an instant solution to reliable cooling of UV lamps. LIA's also provide mounting and a highly efficient method of focusing UV energy on to the curing surface. Many engineers find that the most time consuming aspect of building a UV curing system is controlling lamp temperature and focusing UV energy on to the curing surface. Incorrectly maintaining lamp temperature severely degrades the performance and life of any UV lamp.

Our LIA's offer:


One of the most important features of our LIA's is the construction. This consists of a heavy duty extruded housing which contains an extruded reflector profile. Inside this reflector profile is a high UV reflectance metal insert which conforms to this profile. In addition to being rugged, the extruded reflector provides a large mass which dissipates heat evenly. It allows uniform cooling across the entire lamp length. AC fans with appropriate wiring and lamp mounting provisions are also included.

Two focus versions are available:

Elliptical version provides a
1" wide focus 4 inches from LIA face.

Non-focused version provides
an evenly diffused source of
UV energy on the curing surface

FAQ's for LIA's

How much longer is the LIA than the arc of the lamp?

How do I install the LIA?

Installation instructions

  1. The irradiator can be mounted by using the four flanges on the irradiator (2 per side) making sure that all of the vents have unrestricted air flow. Failure to provide free airflow will result in over heating of the irradiator and/or lamps
  2. The focal point is located 3.5 to 4 inches from the face of the irradiator.
  3. Electrical connections must be made by a qualified electrician. The two lamp leads are made of silicon insulated wire and are to be connected to the ballast according to the manufacturer's specifications
  4. Fan leads need to be connected to specified voltages.
  5. Fans may require a time delay of 1 to 1.5 minutes to allow for lamp startup.
  6. Connect the interlock leads as a safety switch to the power supply. They will indicate open or closed state of the irradiator (shuttered version only).

Are these available with shutters?

Yes, an air cylinder powered shutter is a standard option. Air pressure that you supply is required for operation. Air pressure requirements are different for each size. This information will be included with your order.

Do the LIA's require any maintenance?

Yes, the irradiator will require routine cleaning due to the large amount of air being circulated. Accumulations of dust on the cooling fins and around the vents should be removed routinely. Failure to do so will result in overheating and component failure. Accumulations of dust around the electrical connections will result in arcing and can be extremely hazardous

How are lamps replaced?

Lamp Replacement procedure

  1. Lamp replacements must be done by qualified personnel following proper lockout procedures. Be sure that the irradiator and lamp have cooled before removing the lamp. Lamp removal is achieved by removing the end plate of the irradiator and 4 thumb screws.
  2. Remove two wing-nuts to disconnect the ballast leads. The reflector assembly can now be carefully removed from the Irradiator.
  3. With the lamp side up, the upper halves of the reflector endplates can be removed by unscrewing the two thumbscrews to each endplate.
  4. Remove the upper halves of each lamp support block by removing the 4 flange nut/spring assemblies. Be careful not to loosen the springs since they are necessary to apply the correct pressure to the end fittings of the lamp.
  5. Remove the second lamp lead by removing the remaining wing-nut
  6. The lamp can now be replaced. The new lamps must be free from surface contaminants such as fingerprints. Clean the lamp with a lint free cloth and alcohol prior to installation. The lamp should be handled by the ceramic end fittings.
  7. Replace all components. Note the flange nuts should be installed with the bolt flush with the top of the nut. Over-tightening will result in lamp failure. Two styles: End pull out and rear pull out.
