LED Vs Lamp

Whether or not LED can be used for a particular application will depend on the following:

  • Availability of an adhesive suitable for the application that cures well at 365nm and doesn’t require additional wavelengths.
  • Small spot size (typically no more than 3-5 mm).
  • Low cure depth requirement.
LED best suited where:
  • 365nm is the dominant required wavelength.
  • Cure area is relatively small.
  • Cure depth is low or not critical.
  • Potential surface tackiness is acceptable.
Comparison Chart
LED Lamp
Wavelength 365nm/385nm/400nm or more 250-600nm
UVA Wavelength Availability Single Wavelength Multiple Peak Wavelengths
Optical Power (@365nm) Significant development is underway to increase power efficiency Maximum 1.3 watts
Peak Irradiance (365nm) Maximum 8000 w/cm2 10500 w/cm2
Energy Consumption Low energy consumption. Can be powered by universal power adaptor. High energy requirements. Internal power supply.
Ecological Friendliness No Mercury Lamp contains mercury
On/OFF Time Instant ON/OFF 4 minute warm up
Light Source Lifetime >20,000 hours 3,000 to 4,000 hours typical
Spot Sizes 3-12mm (Significant loss of power with higher spot sizes) Variable with light guides, light lines and accessories
Adhesive Selection Small but growing. Relatively large.
Substrate Selection Heat sensitive and exacting substrates can be used such as thin film, thin plastics, foam plastic, paper, leather, etc. Minimal defect(warp, melt) of the substrate. Same substrates can be used by selecting the appropriate filter.
Available Accessories Few Many
Applications Limited due to fixed wavelengths, spot size and power. Many applications.
