    摘要: A fluid input manifold distributes injected fluid around the body of a bulb to cool the bulb below a threshold. The injected fluid also distributes heat more evenly along the surface of the bulb to reduce thermal stress. The fluid input manifold may comprise one or more airfoils to direct a substantially laminar fluid flow along the surface of the bulb or it may comprise a plurality of fluid injection nozzles oriented to produce a substantially laminar fluid flow. An output portion may be configured to facilitate fluid flow along the surface of the bulb by allowing injected fluid to easily escape after absorbing heat from the bulb or by applying negative pressure to actively draw injected fluid along the surface of the bulb and away.

    摘要: An open plasma lamp includes a cavity section. A gas input and gas output of the cavity section are arranged to flow gas through the cavity section. The plasma lamp also includes a gas supply assembly fluidically coupled to the gas input of the cavity section and configured to supply gas to an internal volume of the cavity section. The plasma lamp also includes a nozzle assembly fluidically coupled to the gas output of the cavity section. The nozzle assembly and cavity section are arranged such that a volume of the gas receives pumping illumination from a pump source, where a sustained plasma emits broadband radiation. The nozzle assembly is configured to establish a convective gas flow from within the cavity section to a region external to the cavity section such that a portion of the sustained plasma is removed from the cavity section by the gas flow.

    摘要: Systems and methods for providing laser sustained plasma light sources are disclosed. Different from conventional laser sustained plasma light sources where one fiber size and one wavelength combination is used in the lamphouse to generate light for different bands and pixel sizes, switchable fiber sizes and wavelength combinations are provided for optimal power output in different wavelength bands and pixel sizes. More specifically, switchable fiber configurations are provided where larger fibers with higher pump powers are used for bigger pixel sizes and higher wavelength bands while smaller fibers are used for smaller pixel size and shorter wavelength bands. Additionally and/or alternatively, pumping schemes are provided where pump wavelengths close to the absorption peak of the gas fill are used for bigger pixel sizes while pump wavelengths away from the gas fill absorption peak are used for smaller pixel sizes.
