Semiconductor Light Matrix™ (SLM)™ Technology

Since 2002, Phoseon Technology has pioneered the use of LEDs for UV curing applications with a 100% focus on UV LED curing technology. Phoseon patented Semiconductor Light Matrix (SLM) technology encapsulates LEDs, Arrays, Optics and Cooling to maximize UV LED curing performance. Each of these four components are strictly engineered into a system that provides maximum UV energy and superior performance while also increasing long-term robustness for demanding applications.


Light Emitting Diodes (LEDs) are solid state devices that produce light when an electrical current flows from the positive (anode) side of the circuit to the negative (cathode) side. Phoseon builds complete light engines from individual diodes versus using pre packaged LEDs. This allows Phoseon to match individual LED characteristics with other components to maximize the total UV energy.


Arrays are a grouping or clustering of individual LEDs. The number, type, and size of LEDs; the shape of the array; and the method of electrically connecting the LEDs all impact the array. Phoseon's array architecture is targeted for both the product, whether air or water cooled, and the target application to insure the optimal performance and reliability for the system manufacturer.


After choosing individual diodes and implementing application-specific arrays, Phoseon then layers optical technologies to direct energy towards the substrate or material to be cured. This use of optics has three benefits: 1) it maximizes the amount of UV energy applied to the material and 2) it lowers the heat generated by the array, and 3) it provides for application specific focused energy.


UV LEDs will last past 20,000 hours if they maintain proper operating temperatures. As LEDs emit more energy, they also generate more heat, which needs to be managed. Phoseon uses patented thermal management techniques that remove excess heat from the system while providing a consistent operating temperature for the diodes to function at maximum performance over their operating lifetime.
