Abstract
A light emitting apparatus includes a substrate, a plurality of solid state light emitting cells having a planar arrangement on the substrate, and a refractive element arranged with the solid state light emitting cells so that light emitted from the light source has a substantially spherical emission pattern. The refractive element may also be arranged with the solid state light emitting cells to mix the emitted light.
Claims98
A light source, comprising:
- a substrate;
- a plurality of solid state light emitting cells having a planar arrangement on the substrate;
- and
- a refractive element arranged with the solid state light emitting cells so that light emitted from the light source has a substantially spherical emission pattern.

A light source, comprising:
- a substrate;
- a plurality of solid state light emitting cells arranged on the substrate to emit light in substantially the same direction;
- and
- a refractive element arranged with the solid state light emitting cells so that the light is emitted from the light source with a substantially spherical emission pattern.
1 more element
A light source, comprising:
- a substrate;
- a plurality of solid state light emitting cells having a planar arrangement on the substrate;
- and
- a refractive element positioned over the solid state light emitting cells so that light emitted from the light source has a substantially spherical emission pattern.
1 more element
A light source, comprising:
- a substrate;
- a plurality of solid state light emitting cells having a planar arrangement on the substrate;
- and
- means for refracting light emitted from the solid state light emitting cells so that the light is emitted from the light source with a substantially spherical emission pattern.
1 more element
A light source, comprising:
- a substrate;
- a plurality of solid state light emitting cells on the substrate;
- the solid state light emitting cells comprising first and second sets of solid state light emitting cells, wherein each of the solid state light emitting cells in the first set includes a phosphor layer and each of the solid state light emitting cells in the second set does not include a phosphor layer;
- and
- a refractive element arranged with the solid state light emitting cells to mix the light emitted from the first and second sets of solid state light emitting cells.
