Latest Patents

One of Zijtveld's latest patents involves an LED with a ceramic green phosphor and a protected red phosphor layer. This innovative design features a ceramic green wavelength conversion element coated with a red wavelength conversion material. The assembly is strategically placed above a blue light-emitting element, ensuring efficient thermal coupling from the red and green converters to the light-emitting element and its associated heat sink. To safeguard the red converter coating from the effects of subsequent processes, a sacrificial clear coating is created above the red converter element. This clear coating can either be a discrete layer of clear material or formed by allowing the red converters to settle at the bottom of their suspension material, creating a converter-free upper layer suitable for further fabrication processes.
