1. A light emitting device comprising:

  • a light transmissive circuit board;

    a first array of solid-state light emitters mounted on, and electrically connected to, a first face of the light transmissive circuit board, wherein the first array of solid-state light emitters are operable to generate excitation light; and

    a photoluminescence wavelength conversion component comprising a mixture of particles of at least one photoluminescence material and particles of a light reflective material, wherein the photoluminescence wavelength conversion component is configured such that in operation a portion of the excitation light generated by the first array solid-state light emitter is emitted through the photoluminescence wavelength conversion component to contribute to a final visible emission product.
