ILLUMINATION DEVICE WITH A WAVELENGTH CONVERTING ELEMENT HELD BY A SUPPORT STRUCTURE HAVING AN APERTURE

An illumination device includes a light source (102), such as one or more light emitting diodes and a wavelength converting element (110) that is mounted on an opaque support structure (112). The support structure includes an aperture (114) with which the wavelength converting element is aligned so...

Beschreibung
Zusammenfassung:	An illumination device includes a light source (102), such as one or more light emitting diodes and a wavelength converting element (110) that is mounted on an opaque support structure (112). The support structure includes an aperture (114) with which the wavelength converting element is aligned so that the converted light is emitted through the aperture. The wavelength converting element may be a rigid structure, such as a luminescent ceramic and the aperture may be a hole through the support structure. The support structure may hold the wavelength converting element so that it is physically separated from the light source, or alternatively, the support structure may place the wavelength converting element in physical contact with the light source.
