    Abstract: Described is a plasma electrode-less lamp. The device comprises an electromagnetic resonator and an electromagnetic radiation source conductively connected with the electromagnetic resonator. The device further comprises a pair of field probes, the field probes conductively connected with the electromagnetic resonator. A gas-fill vessel is formed from a closed, transparent body, forming a cavity. The gas-fill vessel is not contiguous with (detached from) the electromagnetic resonator and is capacitively coupled with the field probes. The gas-fill vessel further contains a gas within the cavity, whereby the gas is induced to emit light when electromagnetic radiation from the electromagnetic radiation source resonates inside the electromagnetic resonator, the electromagnetic resonator capacitively coupling the electromagnetic radiation to the gas, which becomes a plasma and emits light.

    Abstract: This disclosure is directed to devices and methods for generating light with electrode-less plasma lamps. More particularly, the present invention provides plasma lamps driven by a radio-frequency source without the use of electrodes inside the bulb, and a pulse-width modulation device that provides RF power regulation, and related methods. The bulb comprises gaseous material with metal halides and/or light emitters that, when powered, substantially stays in an arc shape state. The switching pulse-width modulation device is operable at specific modulation frequencies, duty cycles, and durations to stabilize or control the arc state/mode, which enables consistent and high efficiencies.

    Abstract: An electrodeless plasma lamp includes a bulb containing a gas-fill and light emitter(s) excited to produce light using radio-frequency (RF) energy. Input and output coupling elements separated from each other by a gap couple RF energy from an RF source to the bulb. One end of the input coupling element is electrically connected to an RF source while the other end is connected to ground. One end of the output coupling element is connected to ground while the other end is connected to the bulb.

    Abstract: An electrodeless plasma lamp array structure uses multiple plasma lamps to produce large amounts of electromagnetic radiation (visible, IR, UV, or a combination of visible, IR, and UV). An M by N array configuration is powered by either a single RF power source or multiple RF power sources. The array incorporates controllers to adjust the power delivered from the RF power source to each lamp within the array. By adjusting the delivered RF power, the intensity of electromagnetic radiation that is emitted from each lamp is controlled independently allowing for the creation of an array of lamps that emit electromagnetic radiation of varying intensity levels at different places within the array. Using lamps with different color temperatures as part of the array allows the color temperature and the color rendering index of the illumination to achieve different lighting conditions.
