Abstract
A light converter comprises: a solid-state optical member configured to absorb light of an excitation wavelength and generate light of an emission wavelength; a base; and a mechanical fastener attaching the solid-state optical member to the base. The light converter may be part of a light engine, a phosphor wheel or an automotive headlight. A method of manufacturing such a phosphor wheel is also provided.
Claims19
A light converter comprising:
- an annular solid-state optical member comprising a phosphor, the annular solid state optical member configured to absorb light of an excitation wavelength and generate light of an emission wavelength;
- a disk-shaped base;
- and
- a cover ring secured with the disk-shaped base and retaining the annular solid-state optical member by engaging an outer rim of the annular solid-state optical member;
- wherein no clamping force is applied to an inner rim of the optical converter.
