Abstract: A plasma lamp for use in a laser-sustained plasma (LSP) light source is disclosed. The plasma lamp includes a gas containment structure for containing a gas, a gas seal positioned at a base of the gas containment structure, a gas inlet, and a gas outlet. The plasma lamp includes a gas swirler including a set of nozzles configured to generate a vortex gas flow and a swirler shaft including an inlet channel for delivering the gas from the gas inlet to the nozzles and an outlet channel for delivering the gas from the gas containment structure to the gas outlet. The plasma lamp includes a distributor including one or more plenums to distribute the gas from the gas inlet into the swirler. The plasma lamp may also include a deflector fluidically coupled to the swirler shaft and extending above the set of nozzles and configured to direct gas flow around the swirler.

Abstract: A laser-sustained broadband light source includes a gas containment structure and multiple jet nozzles. The jet nozzles are configured to direct multiple liquid jets of plasma-forming material in directions to collide with one another within the gas containment structure. The laser-sustained broadband light source further includes a laser pump source configured to generate an optical pump to sustain a plasma in a region of the gas containment structure at a collision point of the plurality of liquid jets and a light collector element configured to collect broadband light emitted from the plasma.

Abstract: Methods and systems for producing a change in a medium. A first method and system (1) place in a vicinity of the medium at least one upconverter including a gas for plasma ignition, with the upconverter being configured, upon exposure to initiation energy, to generate light for emission into the medium, and (2) apply the initiation energy from an energy source including the first wavelength λ1 to the medium, wherein the emitted light directly or indirectly produces the change in the medium. A second method and system (1) place in a vicinity of the medium an agent receptive to microwave radiation or radiofrequency radiation, and (2) apply as an initiation energy the microwave radiation or radiofrequency radiation by which the agent directly or indirectly generates emitted light in the infrared, visible, or ultraviolet range to produce at least one of physical and biological changes in the medium.

Abstract: Shielding radio frequency interference (RFI) using reflector optics is disclosed. A simplified non-sealed reflector is used in conjunction with a mounting system, resulting in desired amounts of visible and non-visible light using radio frequency driven luminaries and emitters without sacrificing output or coverage area. Configurations are disclosed such that achieved RF grounding is compliant with FCC regulations. Accordingly, the disclosed RFI shielding improves optical design options, increased output, and decreased manufacturing costs over traditional sealed enclosures.

Abstract: In electrodeless HID lamps the radio frequency (RF) source is separated from a lamp housing in which vessel containing plasma arc is mounted. This lamp housing is usually designed to maximize the amount of RF energy incident on the plasma arc. The plasma arc, however, cannot convert the entire amount of incident RF energy into light and a portion instead is released as propagating radiation or remains localized RF electromagnetic fields in the vicinity of lamp. In this invention, we introduce field suppression probes: Small, configurable structures that are made of conductive materials that mount directly to the lamp housing or alternately the lamp fixture that is able to suppress unused RF energy that is emanated from the lamp housing or plasma. These probes, when configured with the lamp, can substantially suppress the unused RF energy and prevent EMI emissions and reduce RF feedback that can adversely affect the lamp.

Abstract: In a light source device, a control unit causes an energy density of a laser light in a lighting start region RS when a laser support light is maintained to be lower than an energy density of the laser light in the lighting start region RS when the laser support light is put on. For this reason, when the laser support light is maintained, a laser light L is radiated to the lighting start region RS at an energy density of a degree where sputtering does not occur. Therefore, in the light source device, because sputtering in a light emission sealing body can be suppressed, a sufficiently long life can be realized.

Abstract: The user of plasma light technology and remote lighting control techniques may enable a single master controller to control a large number of lighting fixtures. Multiple lighting fixtures may be equipped with control applications. Each control application may control the radio frequency driver of a lighting fixture that drives the plasma bulbs of the lighting fixture to produce light output for growing plants. The master controlled may execute on one or more computing devices. The master controller may send input instructions to the control applications of the lighting fixtures via a network. The instructions may be implemented by the control applications to command the radio frequency drivers to regulate a spectral distribution and/or intensity of the light output of the lighting fixtures.
