Abstract:
1. A solid-state light source comprising a light emitting diode emitting light of a first wavelength range; a wavelength conversion layer on said light emitting diode, said wavelength conversion layer converting at least a portion of said light of a first wavelength range to light of a second wavelength range, said second wavelength range being different from said first wavelength range; said wavelength conversion layer having at least one via, said via extending through said wavelength conversion layer, said via making electrical contact with said light emitting diode; and said wavelength conversion layer having at least one light extracting element on the surface of said wavelength conversion layer away from said light emitting diode, said at least one light extracting element improving the emission of light from said solid-state light source by reducing the total internal reflection of light at said surface of said wavelength conversion layer away from said light emitting diode.
