摘要： 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.
摘要翻译： 陶瓷绿色波长转换元件（120）用红色波长转换材料（330）涂覆并放置在蓝色发光元件（110）的上方，使得陶瓷元件（120）附着到发光元件（110）上， 从而提供从红色和绿色转换器（330,120）到发光元件（110）及其相关联的散热器的有效的热耦合。 为了保护红色转换器涂层（330）免受后续过程的影响，在红色转换器元件（330）上方产生牺牲透明涂层（340）。 这种透明涂层（340）可以作为透明材料的离散层提供，或者可以通过使红色转换器沉降到其悬浮材料的底部而形成，从而形成可以经受 随后的制造工艺。
