the phosphor layers prior to integration with the LED

Unlike conventional remote phosphor plates, the RadiantFlex technology enables package-level application of phosphor layers to blue (and UV) LEDs. This removes the need for expensive mixing chambers and external reflectors and provides higher performance at lower costs. The RadiantFlex approach also eliminates the need for LED producers to handle phosphor powders and invest in expensive phosphor mixing and dispensing equipment. This will result in considerable R&D savings for LED and lamp manufacturers who typically must spend significant time and resources developing a custom phosphor mixture for each application. As is well-known in the SSL industry, achieving high led high bay light with high luminous efficacy in white LEDs is a complex process plagued with repeatability and uniformity problems since it involves a carefully controlled mixture of several different phosphor compounds. The RadiantFlex technology eliminates those problems and enables detailed analysis and quality verification of the phosphor layers prior to integration with the LED. This results in significant savings in terms of materials and resources that are typically involved in any new LED product development & manufacturing.
PhosphorTech Corporation was formed in 1998 with the support of the Advanced Technology Development Center at the Georgia Institute of Technology. After successfully commercializing many SBIR-funded technologies, PhosphorTech has developed into an independent corporation with internationally recognized accomplishments and high performance products in the fields of photonic semiconductors and novel nano-materials for energy-efficient applications.The RadiantFlex technology and corresponding patent-pending manufacturing process are a direct result of over a decade of research in various remote phosphor application methods, phosphors, and substrate materials.

The technology group has succeeded in reproducibly manufacturing ceramic sintered parts for optical and fluorescent applications within the framework of the three-and-a-half year joint research project wholesale nichia led high bay light funded by Germany’s Federal Ministry of Research (BMBF) that just came to an end in March. They not only offer superior thermal and mechanical qualities, but also high optical refractive indexes of 2 and more, as well as exceptional dispersion values. “This opens up new areas in the Abbe diagram, which systematically depicts the properties of optical materials, which glass was never able to address before. In other words, optic designers now have a larger toolbox to work with,” explains Dr. Volker Hagemann, Senior Scientist at SCHOTT. More compact camera lenses can thus be realized and color defects and aberrations minimized. Unlike glass, some transparent ceramics have an extremely broad light transmission window that ranges from the ultraviolet (UV) all the way to the infrared (IR) wavelength range of 6 micrometers. This also makes the new material that is extremely insensitive to environmental influences of great interest for geo-observations of raw material deposits using special cameras.
