Patent ID: 8169135

Claim:
A solid state lighting device comprising: a semiconductor light emitting component packaged on a reflective substrate, said semiconductor light emitting component emitting a primary first light; a long pass dichroic filter disposed to receive said primary first light that is emitted from said semiconductor light emitting component, said long pass dichroic filter reflecting back at least 50% of said primary first light that is emitted from said semiconductor light emitting component; a first wavelength down-conversion layer on said reflective substrate, said first wavelength down-conversion layer absorbing said reflected primary first light from said long pass dichroic filter, said reflected primary first light from said long pass dichroic filter exciting a forward second light from said first wavelength down-conversion layer; a light diffuser member positioned on top of said long pass dichroic filter; and a power line electrically connected to said semiconductor light emitting component.
