UV LED Curing Solutions
What is UV-LED Curing?
- UV - Light Emitting Diode (UV-LED)
- UV LED is an alternative UV Curing system based on solid state devices.
- Narrow wavelength band
- Monochromatic wave output: 365 / 385 / 395 / 405 nm.
- Typical peak output for use in graphic arts 385 nm or 395 nm.
- Maximum bandwidth of 40 nm.
- Power Output of LED lamps.
- UV LED lamps - Up to 24 W/cm2.
- (24 Watts/cm2 – 395 nm; 12 Watts/cm2 – 365 nm)

Highlights:
- No IR radiation and minimal heat transfer to substrate.
- LED systems are more compact.
- Low Voltage – simpler and safer.
- Instant On/Off – No shutters are necessary (Traditional lamps require cooling down in idling mode prior to going back to full power).
- Longer Life: 60,000 hours.
- Consistent UV output over operating life.
- No UVC and No ozone created – Eliminating need for exhaust.
- Does not contain heavy metals (Mercury).
- LEDs are more efficient than bulb technology with 15-20% of the energy applied transformed into light.
- Since the wattage is low, this heat is not very high.
- No rotating or moving parts.
- No need of compressed air.
Mercury Arc UV vs. UV LED:
| UV LED | Mercury Arc UV Lamp | |
|---|---|---|
| Size | Compact | Large |
| Power | 70-80% Less than UV Lamp | High |
| Start Time | Instant ON | Long |
| Heat Production | Low | High |
| Environment | No Mercury | Mercury Bulbs |
| Lamp Life | 20,000 – 60,000 hours | 700-2000 hours |
| Dangers | Slight Skin and Eye | Skin, Eye, Voltage, Heat, Ozone, Mercury Leakage |
| Equipment Cost | High | std. |
