Abstract
There is provided a spread illuminating apparatus to improve a coupling efficiency between a light conductive member and a spot-like light source. A claw ( ) of an upper frame ( ) is fitted to a recess ( ) of an LED ( ), and generates a spring force in a direction of a light conductive member ( ) (a spring force in a longitudinal direction of the light conductive member ( )) in a fitted condition to press the LED ( ) toward the light conductive member ( ). Thus, the light conductive member ( ) and the LED are excellently and tightly attached to each other, and surely positioned, and the coupling efficiency of the light conductive member ( ) with the LED is excellent. Since the claw ( ) of the upper frame is fitted to the recess ( ) in the LED ( ), deviation of the LED ( ) in a direction orthogonal to the longitudinal direction of the light conductive member ( ) is suppressed, and the light conductive member ( ) and the LED ( ) can be surely positioned accordingly, and the coupling efficiency of the light conductive member ( ) with the LED ( ) can be further improved.
