ABSTRACT:
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.
