Phoseon's proprietary Semiconductor Light Matrix (SLM)™ technology uses a tightly-integrated array of high-intensity light-emitting semiconductor devices. Ultraviolet SLM arrays produce significantly higher intensity light than other LED ultraviolet curing technologies. Phoseon's SLM approach is to use proprietary packaging, optics, and thermal design to maximize UV energy, provide superior performance, and deliver long-lasting field-tested products.
Who is Phoseon Technology?
Phoseon Technology has pioneered Semiconductor Light Matrix (SLM) technology utilizing high power UV LED technology to manufacture the environmentally cleanest, coolest operating, highly efficient ultraviolet curing products on the market. Phoseon is a venture-funded, privately-held corporation founded in 2002 headquartered in Hillsboro, Oregon.
What is ultraviolet LED?
Ultraviolet (UV) LED stands for ultraviolet light emitting diode. A UV LED is an electronic light source with electromagnetic radiation that has a wavelength shorter than that of visible light but longer than x-rays.
What is Ultraviolet curing?
Ultraviolet curing is the polymerization of UV sensitive materials, rather than drying through the evaporation of solvents.
Where did the name Phoseon come from?
The etymology of “Phoseon" references “long-lasting light," conveying reliability, endurance, and our long-term commitment to deliver to the world bright, industrial light sources characterized by insignificant energy consumption or environmental impact.
What is the Semiconductor Light Matrix (SLM) Technology?
SLM is a unique technology for producing UV light. Forty years ago, mercury-based arc lamps were the only UV light source available to initiate the UV curing process. New bulb-based light sources such as Excimer bulbs, microwave sources have been introduced, but the basic technology remains the same. Phoseon Technology has developed a “bulbless" Semiconductor Light Matrix (SLM) technology to produce UV light for curing applications. The future of high intensity UV technology is small, cool and clean, with no bulb replacement required.
Phoseon's Semiconductor Light Matrix (SLM) technology combines a dense array of light emitting semiconductor devices, with micro optics and advanced thermal technology in a cost-effective MOEMS (micro opto electro-mechanical system) package. The result is a high intensity UV light system that offers an efficient, scalable, safe, long-life, and environmentally friendly alternative to traditional UV sources.
What is an Arc lamp?
An arc lamp or arc light is the general term for a class of lamps that produce light by an electric arc. An arc lamp is also called a discharge lamp, or an arc discharge lamp. The type of lamp is often named by the gas contained in the bulb; including neon, argon, xenon, krypton, sodium, metal halide, and mercury. The common fluorescent lamp is actually a low-pressure mercury arc lamp.
What application markets does Phoseon support?
Phoseon's ultraviolet curing products are currently used in production applications for ultraviolet curing of printing, coatings, and adhesives. In addition to printing, coatings and adhesives, there are many other applications for implementing Phoseon's technology.
How is the SLM technology different than other UV LED solutions available on the market?
Phoseon's proprietary Semiconductor Light Matrix (SLM) technology is a breakthrough in high power light applications. It uses a tightly-integrated array of high-intensity light-emitting semiconductor devices. Ultraviolet SLM arrays produce significantly higher intensity light than other LED ultraviolet curing technologies. The light produced by traditional UV LEDs is limited by the discretely packaged design. Phoseon's SLM approach is to use proprietary packaging, optics, and thermal design to optimize the output.
What is the difference between traditional UV lamps and UV LED sources?
Traditional Arc lamps use an electric arc inside a mercury gas to excite atoms, which then decay, emitting photons. Microwave lamps excite the gas via microwave emission. Xenon lamps use Xenon gas (no mercury) but can only be “flashed."
UV LED Semiconductors (UV LED) emit a narrow bandwidth of light at the junction where doped semiconductor positive holes join with negative electrons when voltage is applied.
What is unique about Phoseon's products?
Phoseon is the original inventor of patented SLM™ technology. None of the Phoseon products use bulbs or contain mercury.
SLM technology offers the following benefits compared to arc lamps:
1) More reliable.
2) High speed curing < 1 sec for inks.
3) Pinning and full cure of inks and coatings.
4) Special technology for surface curing.
5) No heat damage, <20 degree temperature increase during curing.
6) No shutters, no ozone, no mercury, no safety issues, less heat exhaust, less power consumption.
