WAVELENGTH CONVERTING ELEMENT COMPRISING CERAMIC CAPSULE |
| 摘要 |
A wavelength converting member is provided, comprising a sealed capsule at least partly made of sintered polycrystalline ceramic, for example sintered polycrystalline alumina, said capsule defining at least one sealed cavity; and—a wavelength converting material contained within said sealed cavity. The wavelength converting member has high total forward transmission of light, high thermal conductivity, high strength and provides excellent protection for the wavelength converting member against oxygen and water. The wavelength converting member can advantageously be applied in a light emitting arrangement or as a color wheel for a digital image projector. |
