ABSTRACT:
A plurality of light emitting diode pellets arranged on a base are surrounded by a partition member and an outer frame member fixed on the base to mount an elongated lens on the opening portion thereof. A certain number of partition members are arranged between the base and the lens having recessed portions so as to partition each pellet or groups of several pellets. The upper ends of the partition members are inserted into recessed portions of the lens. Thus, when an arbitrary light emitting diode pellet is energized, light from the energized pellet does not spread to the non-light emitting pellet portions, thus clearly discriminating between the light emitting portions and non-light emitting portions.
