Abstract
A replacement lamp for a cinema poster display case. Light from a linear array of white-light LEDs reflects off a concave reflector to an illumination plane at or near a front face of the display case. The concave reflector intersects with surface normals from the LED emission faces along an intersection line. The concave reflector has proximal and distal portion on opposite sides of the intersection line. The illumination plane is disposed on an opposite side of the LEDs from the intersection line. The illumination plane has a proximal portion near the LEDs and a distal portion away from the LEDs. Light reflected from the LEDs off the proximal portion of the concave reflector is directed to the distal portion of the illumination plane. Light reflected from the LEDs off the distal portion of the concave reflector is directed to the proximal portion of the illumination plane.
