Patent ID: 8277064

Claim:
Light source having a predefined external appearance during non-operation, the light source comprising a light emitter a light conversion element, the light emitter emitting visible light of a first color (Be) via the light conversion element in a direction away from the light source, the light conversion element comprising a first luminescent material for converting at least a part of the light of the first color (Be) into light of a second color (Y 1 , Y 2 ) different from the first color (Be), a conversion material for converting at least a part of ambient light (A) originating from outside of the light source impinging on the conversion material into light of a third color (Ba) different from the second color (Y 1 , Y 2 ), the conversion material being at least partially to a surface of the light conversion element, facing away from the light emitter, in a first regular pattern defining openings in between adjacent parts of conversion material, through which light of the first color (Be) and light of the second color (Y 1 , Y 2 ) are emitted from the light conversion element, and a mirror layer applied in a second regular pattern corresponding to the second regular pattern of the conversion material, the mirror layer being disposed between the conversion material and the light emitter for improving the efficiency of the light source by recycling light of the first color (Be) and light of the second color (Y 1 , Y 2 ).
