Abstract:
1. A Lucent Waveguide Plasma Light source to be supported by a support comprising: a fabrication of solid-dielectric, lucent material, having; a Faraday cage: provision for introducing plasma exciting electro-magnetic waves, into the waveguide; the arrangement being such that on introduction of electro-magnetic waves of a determined frequency a plasma is established in the void and light is emitted via the Faraday cage; wherein the said provision includes: a transition waveguide providing for introduction of plasma exciting microwaves into a void-containing-waveguide delimited in the lucent body by the Faraday cage and a magnetron for generating microwaves to excite a light emitting plasma in the void in the lucent waveguide formed by the fabrication and the Faraday cage; wherein there is included: a finned heat dissipation member for dissipating heat from the magnetron to the ambient atmosphere and means on the dissipation member for heat conductingly clamping the heat dissipation member to at least one of an anode and magnets of the magnetron; and wherein: the heat dissipation member supportingly connects the magnetron, transition waveguide and the lucent fabrication to the support, whereby the fins define a heat dissipating, convective airway through the said member which is a support-and-dissipation member.
