Patent ID: 8888349

Claim:
A replacement lamp ( 1 ) for a display case, the display case having an illumination plane ( 20 ) at which viewable objects are placeable, comprising: a plurality of LEDs ( 3 ) spaced in a linear array, each LED ( 3 ) having a surface normal (SN) and emitting light into an angular distribution centered around the respective surface normal (SN), the surface normals (SN) all being generally parallel; an elongated concave reflector ( 9 ) that reflects light emitted from the LEDs ( 3 ) onto the illumination plane ( 20 ), the concave reflector ( 9 ) intersecting with the surface normals (SN) along an intersection line (I), the concave reflector ( 9 ) extending from a proximal portion ( 9 P) near the LEDs ( 3 ) to a distal portion ( 9 D) away from the LEDs ( 3 ), the proximal and distal portions ( 9 P, 9 D) being on opposite sides of the intersection line (I); wherein the illumination plane ( 20 ) is disposed on an opposite side of the LEDs ( 3 ) from the intersection line (I); wherein the illumination plane ( 20 ) has a proximal portion ( 20 P) near the LEDs ( 3 ) and a distal portion ( 20 D) away from the LEDs ( 3 ); wherein light reflected from the LEDs ( 3 ) off the proximal portion ( 9 P) of the concave reflector ( 9 ) is directed to the distal portion ( 20 D) of the illumination plane ( 20 ); and wherein light reflected from the LEDs ( 3 ) off the distal portion ( 9 D) of the concave reflector ( 9 ) is directed to the proximal portion ( 20 P) of the illumination plane ( 20 ).
