Abstract
A wavelength converting layer may have a glass or a silicon porous support structure. The wavelength converting layer may also have a cured portion of wavelength converting particles and a binder laminated onto the porous glass or silicon support structure.
Claims20
A wavelength converting layer comprising:
- a porous support structure including one or more quartz or glass mesh layers;
- and
- a cured layer of wavelength converting particles and a binder laminated onto the porous support structure.
A light emitting device comprising:
- a wavelength converting layer, and
- a semiconductor active layer,
- the wavelength converting layer including a porous support structure including one or more quartz or glass mesh layers, and a cured layer of wavelength converting particles and a binder laminated onto the porous support structure,
- the wavelength converting layer being positioned and arranged to absorb first light emitted from the active layer at a first wavelength, and to emit second light at a second wavelength different from the first wavelength.
