Phoseon’s patented Semiconductor Light Matrix (SLM) technology encapsulates LEDs, arrays, optics and cooling to maximize UV LED performance. These components are engineered into high intensity LED light engines that enables significant process improvements for a wide array of applications in life sciences and industrial manufacturing.
An LED is a solid-state device that produces light when an electrical current is allowed to flow from the positive (anode) side of the circuit to the negative (cathode) side. Phoseon builds high intensity LED light engines from individual diodes versus using pre-packaged LEDs to maximize the total UV energy.
How the LEDs are combined, the number and type of LEDs chosen, the shape, the method of electrically connecting the LEDs, and even the size of the LEDs all have significant impact on the performance of the system. If built correctly, it can be a high power UV LED array.
The UV LED optics is one of the most important differentiators. The science of optically improving the LEDs to maximize their UV output is key to the light engine’s final capability. Based on the end application the optical engineer has to decide what shape, form, and material best utilizes the LED’s unique characteristics.
UV LED arrays are typically cooled with either air or liquid. It is important to note that as the LEDs emit higher output power, the more heat is generated. The ability of to control and remove heat has become more crucial to building reliable systems.
