LIGHT EMITTING PLASMA LIGHTING APPARATUS INCLUDING RF SHIELDING

摘要

A light emitting plasma lighting apparatus may include at least one conductive RF shielding baffle located in a reflector housing between an emitter and a window. The at least one RF shielding baffle may include a planar body portion aligned generally perpendicular to an outer surface of the plasma bulb to minimize interference with light emitted from the plasma bulb. The at least one RF shielding baffle is grounded to absorb a portion of an RF field emitted by the emitter. A light emitting plasma emitter may include a conductive RF shielding plate coupled to a body portion of the emitter and positioned over the bottom surface of a puck which supports a plasma bulb. The RF shielding plate may be formed to include an aperture to expose the plasma bulb. The RF shielding plate is grounded to absorb a portion of a RF field emitted by puck.
