Abstract: An electrodeless plasma lamp and a method of generating light are provided. The plasma lamp may comprise a power source to provide radio frequency (RF) power, and a bulb containing a fill that forms a plasma when the RF power is coupled to the fill. The plasma lamp further comprises a resonant structure having a quarter wave resonant mode. The resonant structure includes a lamp body comprising a dielectric material having a relative permittivity greater than 2, an inner conductor, and an outer conductor. The power source is configured to provide the RF power to the lamp body at about a resonant frequency for the resonant structure.

Abstract: An electrodeless plasma lamp is described that employs acoustic resonance. The plasma lamp includes a metal enclosure having a conductive boundary forming a resonant structure, and a radio frequency (RF) feed to couple RF power from an RF power source into the resonant cavity. A bulb is received at least partially within an opening in the metal enclosure. The bulb contains a fill that forms a light emitting plasma when the power is coupled to the fill. The RF power source includes a controller to modulate the RF power to induce acoustic resonance in the plasma.

Abstract: The present disclosure relates to apparatuses and methods to control an electrodeless plasma light source. In various embodiments, an apparatus is provided that includes an electrodeless plasma lamp with a lamp driver circuit. The lamp driver circuit may include a voltage-controlled oscillator to provide radio frequency power to the electrodeless plasma lamp. A radio frequency power detector is coupled to an output of the voltage-controlled oscillator to detect a level of reflected power from the electrodeless plasma lamp. A microprocessor is configured to receive signals from the radio frequency power detector and control a frequency of the voltage-controlled oscillator to minimize the reflected power from the electrodeless plasma lamp.

Abstract: An electrodeless plasma lamp and a method of controlling operation of a plasma lamp are provided. The plasma lamp may a power source to provide radio frequency (RF) power and a lamp body to receive the RF power from a feed. The lamp body may comprise a dielectric material having a dielectric constant greater than 2 and bulb is provided that contains a fill that forms a plasma that emits light when at least a portion of the RF power is coupled to the fill. A light guide directs light from the bulb to a photosensor that is shielded from light output from a front side of the lamp body. The lamp includes a drive circuit to control operation of the lamp based on a level of light detected by the photosensor.

Abstract: A lamp and methods of forming are shown. In one example, a dielectric layer is formed over a gap between conductors in a plasma lamp. Electric arcing is reduced or eliminated, thus allowing tighter gaps and/or higher voltages. In one example a glass frit method is used to apply the dielectric layer. A lamp is shown with a barrier layer that prevents tarnish such as tarnish from sulfur exposure. The barrier layer reduces or prevents degradation of the lamp due to conversion of a conductor material to non-conductive tarnish material.
