Patent ID: 8121166

Claim:
A side-emitting light device comprising: a first sub-assembly, said first sub-assembly having a first substrate; at least one light source disposed on said first substrate; a first luminescent plate having a first surface and an opposite second surface, wherein said first surface of said first luminescent plate is optically bonded with said at least one light source of said first sub-assembly, and wherein said at least one light source of said first sub-assembly emits light of a wavelength capable of exciting luminescence light from said first luminescent plate; a second sub-assembly, said second sub-assembly having a second substrate; at least one light source disposed on said second substrate; a second luminescent plate having a first surface and an opposite second surface, wherein said first surface of said second luminescent plate is optically bonded with said at least one light source of said second sub-assembly; wherein said at least one light source of said second sub-assembly emits light of a wavelength capable of exciting luminescence light from said second luminescent plate; wherein said first and said second sub-assembly are arranged having said second surfaces of said first and said second luminescent plates optically bonded together in a face to face relationship with an optical binding agent so that said at least one light source on said first substrate is facing said at least one light source on said second substrate with said optical binding agent interposed therebetween.
