Abstract: A ceramic green wavelength conversion element (120) is coated with a red wavelength conversion material (330) and placed above a blue light emitting element (110) such that the ceramic element (120) is attached to the light emitting element (110), thereby providing an efficient thermal coupling from the red and green converters (330, 120) to the light emitting element (110) and its associated heat sink. To protect the red converter coating (330) from the effects of subsequent processes, a sacrificial clear coating (340) is created above the red converter element (330). This clear coating (340) may be provided as a discrete layer of clear material, or it may be produced by allowing the red converters to settle to the bottom of its suspension material, thereby forming a converter-free upper layer that can be subjected to the subsequent fabrication processes.
