Patent ID: 7012542

Claim:
A polychromatic light indicator system for monitoring a power amplifier disposed within a housing, said light indicator system comprising: sensing circuitry for sensing different modes of operation of the amplifier; a luminaire comprising: a polychromatic light source for emitting output light of selectably different color; a reflector assembly disposed adjacent to the light source and having a plurality of reflective surfaces for receiving and reflecting the output light emitted by the light source; and an indicator lens disposed adjacent to the reflector assembly for receiving and refracting the output light reflected by the reflector assembly such that the output light is displayed to an observer; and control logic circuitry for receiving input signals from the—sensing circuitry and for selectably controlling the polychromatic light source such that each different sensed mode of operation of the amplifier is indicated by a luminaire output light of a different color wherein the control logic circuitry further controls the polychromatic light source such that the color of the output light displayed is determined by a hierarchy of modes operation of the amplifier and wherein the different sensed modes of operation of the amplifier comprise: a cower on mode; a signal present mode; a clipping mode; and a protection mode.
