Patent ID: 8564109

Claim:
An illumination apparatus, comprising: an LED (Light Emitting Diode) module including a substrate formed in a rectangular plate configuration, an interconnect layer provided on a front surface of the substrate, a reflector film covering the front surface of the substrate, and an LED package mounted on the interconnect layer; a light guide plate provided on an LED package mounting surface side of the LED module, the light guide plate being transmissive with respect to light emitted from the LED package; and a support body supporting the LED module and the light guide plate, a reflective surface of the support body being provided between a portion supporting the LED module and a portion supporting the light guide plate, the reflective surface being reflective with respect to the light emitted from the LED package, the LED module being tilted relative to the reflective surface with the LED package mounting surface being toward the reflective surface, an angle between the LED module and the reflective surface being less than 90°, the interconnect layer including a first interconnect layer formed in one continuous pattern extending in a longitudinal direction of the substrate, and a second interconnect layer divided into a plurality in the longitudinal direction of the substrate, portions of the interconnect layer being exposed from the reflector film as pads, the LED package being mounted on the pads.
