Patent ID: 7473013

Claim:
An indicator lamp comprising: a light-emitting element; and a light-emitting element lens, wherein said light-emitting element lens includes a lens body having a light-emitting element mounting cavity formed at a rear of said lens body, said light-emitting element being mounted in said light-emitting element mounting cavity, said lens body having an inverted conically shaped peripheral surface for fully reflecting and forwardly re-directing light emitted from said light-emitting element, said peripheral surface having three linearly sloped sections, each of said sloped sections being sloped relative to an axis of said light-emitting element lens at an angle different from that of the other sloped sections so as to define circumferential corners at points of discontinuity between adjacent ones of said three linearly sloped sections, wherein said circumferential corners are arranged so as to scatter light emitted from said light-emitting element forwardly to provide concentric emission light fluxes as viewed from a side of said front surface of said light-emitting element lens.
