An LED indication lamp has desired luminous intensity distribution characteristics
without need for any light-emitting diode of a special shape. The LED indication
lamp comprising a plurality of light-emitting diodes and having specified luminous
intensity distribution characteristics is further provided with a condenser lens.
The light-emitting diodes are arranged in a pattern corresponding to a luminous
intensity distribution pattern determined according to the luminous intensity distribution
characteristics. The light-emitting diodes thus arranged and the condenser lens
are arranged so that light emitted from the light-emitting diodes in the luminous
intensity distribution pattern through the condenser lens satisfies the luminous
intensity distribution characteristics.
