Illumination device for simulation of neon lighting
InactiveUS6874924B1Readily apparentLighting support devicesPoint-like light sourceSurface emissionLight source
An illumination device includes an elongated and substantially cylindrical waveguide, which has a light-emitting outer surface and an interior semi-reflective portion spaced at a predetermined distance from the light-emitting outer surface. A channel is defined through a portion the waveguide along the length thereof and is adapted to receive an elongated light source such that emitted light is directed into at least one of the wall surfaces defined by the channel. As the light enters and is directed about the circumference of the waveguide, a portion of the light is scattered and emitted through the light-emitting outer surface of the waveguide. Light is also reflected by the semi-reflective portion, causing additional light to be scattered and emitted through the light-emitting outer surface of the waveguide. The result of this guiding, reflecting, and emission of light is a substantially homogenous and uniform light intensity pattern over the light-emitting outer surface of the waveguide so as to simulate neon lighting.

A cylindrical waveguide with a mode converter transforms a whispering gallery mode from a gyrotron cylindrical waveguide with a helical cut launch edge to a quasi-Gaussian beam suitable for conveyance through a corrugated waveguide. This quasi-Gaussian beam is radiated away from the waveguide using a spiral cut launch edge, which is in close proximity to a first mode converting reflector. The first mode converting reflector is coupled to a second mode converting reflector which provides an output free-space HE11 mode wave suitable for direct coupling into a corrugated waveguide. The radiated beam produced at the output of the second mode converting reflector is substantially circular.
