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,
- all or at least a portion of the thickness of the porous support structure lacking any of the wavelength converting particles, and
- all or at least a portion of the thickness of the cured layer lacking any fibers or strings of the one or more mesh layers.

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,
- all or at least a portion of the thickness of the porous support structure lacking any of the wavelength converting particles,
- all or at least a portion of the thickness of the cured layer lacking any fibers or strings of the one or more mesh layers, and
- 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.
3 more elements
A method comprising:
- forming a porous support structure that includes one or more quartz or glass mesh layers;
- forming a layer that includes wavelength converting particles and a binder;
- and
- heat or pressure laminating the layer of the wavelength converting particles and the binder onto the porous support structure to form a laminated wavelength converting layer, so that all or at least a portion of the thickness of the porous support structure lacks any of the wavelength converting particles, and so that all or at least a portion of the thickness of the layer of the wavelength converting particles and the binder lacks any fibers or strings of the one or more mesh layers.
