The fourth generation of AMS’s award-winning Peak UV Curing System — PEAK LED-UV™ — represents a transformational solid-state product for printing, packaging and finishing industries.
PEAK LED-UV FEATURES
The PEAK LED-UV™ system brings revolutionary high-power LED UV curing in a compact, solid-state device at a fraction of the energy costs and complexity of a conventional arc-lamp UV system.
- High intensity, pure, uniform LED UV energy delivered to work surfaces at distances up to 4 inches (100 mm) away.
- Ability to operate at just 20% of the energy required by today’s high-power UV arc lamp systems.
- Instant On/Off digital control of the lamp module eliminates warm-up time, and saves hundreds of hours annually.
- No IR heat is emitted from the LED light source which protects the press and elminates substrate issues.
- Potential for 20,000+ hours from the LED light source obviates the need for replacement bulbs.
- Solid-state design means no moving parts that might lead to costly downtime and maintenance.
- Compact DC power, control and water cooling eliminate the need for an invasive footprint.
- Small, scalable, interchangeable module is designed to integrate easily into all OEM equipment.
BREAKTHROUGH LED UV BRIGHTNESS AND POWER
A breakthrough in high-brightness, thermally efficient LED chip technology has led to a new AMS architecture for powerful, ultra-efficient, solid-state LED UV curing devices.
Most LED UV devices measure radiant power at the chip surface or at the emitter window. PEAK LED-UV measures it at the work surface, which is typically 1.5 inches (3.8 cm) to 4 inches (10 cm) away.
PEAK LED-UV modules provide the highest UV radiant intensity available at the work surface, measured at over twice the intensity compared to even recent generations of comparable LED devices.
The PEAK LED-UV module further allows positioning at varying distances from the substrate without significant loss of uniformity or optical power, a critical requirement for integration on printing and process machinery.
SCALABLE, SOLID-STATE DESIGN
PEAK LED-UV modules were engineered with a flexible architecture to scale between 3 and 80+ inches wide
(80 mm to greater than 2 meters) and to accommodate virtually any machine integration requirement or curing scenario.
The powerful, rugged PEAK LED-UV units come in a profile just 3.5 inches (8.9 cm) square, and are designed to quickly integrate into most machines on the market.
An ultra efficient water-cooled extrusion forms the backbone of the durable unibody housing, and the no moving parts are available to wear or fail.
By integrating a patent-pending optical, thermal and interconnect design into a scalable module, AMS has engineered an answer to digitally-oriented UV curing requirements and clean, energy-efficient, green technology demands of modern printing and finishing.
LED UV INKS AND COATINGS
New LED-compatible inks and coatings are emerging to react to the intense, pure UV spectral output of LED UV light, which emits no infrared heat, involves no mercury, and generates no ozone during the curing process.
In contrast to mercury (Hg) lamps, LEDs generate pure UV spectral output at several peak wavelengths, enabling a precision match to the photo-initiation and absorption requirements of inks, coatings and adhesives.
A new era of UV chemistries are being developed by formulators to address the phenomenal opportunities presented by LED UV, and to create instant, VOC-free drying results at a fraction of the traditional effort and costs.

GREENER UV FOOTPRINT
While UV printing and curing is already widely known for its energy, waste and emission-reduction benefits, LED-UV technology brings the UV process to another level.
For starters, LED UV lamps contain zero mercury, produce no ozone and can be effective with as little as 20% of the energy required by conventional UV lamps.
With a lifetime up to 20x longer than conventional UV lamps, the PEAK LED UV system requires minimal maintenance and produces no consumables waste.
And because the PEAK LED-UV system produces ultraviolet output in the UV-A range, it is safer and more human tolerant than the short wavelengths produced by mercury lamps.
In terms of system architecture, a compact, modular DC power supply, control cabinet and a low capacity heat exchanger or chiller are all that are required to operate the system.
Large, high-voltage transformer and control cabinets with unsightly and complex air exhaust runs for ozone extraction and lamp cooling are no longer required.
POSITION AND WAVELENGTH FLEXIBILITY
With the patent-pending design of the PEAK LED-UV system, effortlessly relocate modules between positions on a machine to match the wavelength, energy and sequence of inks, primers, coatings and adhesives to the job being run.
Formulators have discovered that a combination of high power and spectral variation can optimize the cure of pigmented, clears and opaques in different ways.
Therefore, the wavelength output of the light source must be flexible in order to cure properly at production speeds.
Because of this requirement, identical, interchangeable PEAK LED-UV modules are available in multiple spectral outputs to mix and match wavelengths on a machine in order to accommodate the optimal curing requirements of the inks and coatings in each unit.
Solid-state DC power supplies automatically adjust to the wavelength output of each module. Electronic control of the wavelength in a single module is planned in upcoming releases.
MACHINE COMPATIBILITY
The PEAK LED-UV series is available in several modular package designs to accommodate the needs of Digital, Offset and Flexo machine manufacturers of all makes and varieties.
The LED-UV XP module series (shown) provides extendable length coupled with exchangeable position technology for maximum access, location and flexibility.
The LED-UV FP module series provides extendable length but with a fixed position adaptation, suitable for machines where routine access to lamp modules is not required.
And because of its compact design and simple PLC integration, the system is easily retrofitted onto existing equipment.
