The unique LED engine design enables several degrees of freedom for power and color wavelength customization. Not only can the remote phosphor element be replaced but the internal LED pump sources can also be replaced enabling spectral coverage anywhere from the UVC to the infrared. The use of a remote phosphor plate also transforms the pixelated and non-uniform LED emission profile into a uniform Lambertian emitter that can be built into different sizes and shapes then coupled to external optics. The use of a remote phosphor plate not only enables a higher degree of color control and high color quality, but it has been shown to reduce the overall thermal load on the LED system leading to higher conversion efficiencies and longer lifetimes.
