  • Patent number: 8592788
    Abstract: A plasma pinch extreme ultraviolet source using lithium vapor requires surrounding surfaces that are heated or cooled in order to evaporate the desired quantity of lithium, typically setting the vapor pressure of lithium at a pressure of a few torr. Two distinct surfaces within the whole set are designated as the electrodes that emit and receive the high current of the plasma pinch. A method is described whereby the temperature of these designated electrode surfaces is manipulated in order to condense lithium and provide a liquid metal protective layer to absorb both plasma and extreme ultraviolet heat thereby controlling electrode erosion. A further method is described that provides a protective flow of liquid lithium exactly on the axis of the pair of discharge electrodes.

    Abstract: The present invention relates to a luminous device with a heat pipe formed therein and a heat pipe lead for a luminous device. The present invention provides a luminous device including a heat pipe lead or electrode and a luminous chip mounted onto the heat pipe lead or electrode. The luminous device of the present invention further comprises a heat dissipation member, such as a heat radiating plate or thermoelectric device, installed at an end of the heat pipe lead or electrode. Therefore, through the heat pipe lead or electrode of the present invention, a higher heat dissipation effect greater can be obtained as compared with the conventional one. As a result, it is possible to reduce thermal stress on a luminous device and to prevent the occurrence of a phenomenon in which external impurities penetrate into the luminous device. In addition, the cooling efficiency and the light-emitting efficiency of a luminous chip can be maximized by further disposing a heat dissipation member outside the heat pipe.

    Abstract: Heat management devices and structures are disclosed that can be used in lamps having solid state light sources such as one or more LEDs. Some lamp embodiments comprise one or more phase change radiators that utilize the latent heat of fluids to circulate and draw heat away from the LEDs and radiate the heat into the ambient, allowing for the LEDs to operate at a lower temperature. Some phase change radiators according to the present invention can comprise a main radiator body and multiple radiator coolant loops mounted to the body. The present invention relies on the circulation of heated fluid through the radiator body to radiate heat from the LEDs. The heated liquid moves away from the LEDs and is circulated back to thermal contact with the LEDs thought the coolant loops.

A reflective mirror is arranged above the low-pressure mercury lamps so as to reflect the ultraviolet light emitted by the low-pressure mercury lamps. An exhaust passage defined by the reflective mirror suctions air around the low-pressure mercury lamps and exhausts the suctioned air to outside. The reflective mirror has a plurality of openings arranged along a longitudinal direction of the low-pressure mercury lamps, and a part of the openings has a size different from a size of other parts of the openings.

  • Patent number: 5504666
    Abstract: A light bulb cooling jacket is adapted to confine a light bulb in a space through which cooling liquid, such as water, may be circulated. The light bulb cooling jacket includes an shell having a rim, the rim defining an opening in the shell. A stopper fits in the opening in the shell and seals against the rim of the shell. The stopper has an aperture in it. The aperture is adapted to receive a portion of a light bulb, which is held and sealed in place in the aperture. The means employed to hold the bulb in place is adapted to engage a generally cylindrical portion of the light bulb, such as the neck of a standard 1000 W bulb. An important characteristic of the present invention that follows from this construction is that the light bulb cooling jacket may be used with a variety of standard high intensity light bulbs. Ports are provided in the stopper for introducing and withdrawing cooling liquid from the space enclosed by the shell and the stopper.

    Abstract: A magnetron having an anode cylinder, cooling fins fixed thereto, permanent magnets vertically superposed on the anode cylinder and a yoke, serving as a magnetic path, for surrounding these components. The cooling fins extend on the windward direction to facilitate a discharge of the air in the orthogonal direction to the air blowing direction by an arrangement such that an outer width of the fins and a width of the yoke or the former is equalized to a diameter of the anode cylinder. Also included are a dielectric heater having a heating space for accommodating materials for heating and a space for accommodating the magnetron, an inverter power supply and a cooling air blower. The cooling air is discharged to the heating space and/or to the outside via a vent hole formed in a partition wall after impinging on the anode cylinder while cooling the fins.

  • Patent number: 4994705
    Abstract: A water-cooled low pressure gas or mercury vapor lamp which utilizes a cooling system to keep the lamp cool in the area where useful radiation is emitted. This is accomplished by means of a cooling chamber directly adjacent to the gas or mercury vapor discharge chamber. A cooling fluid is injected into the cooling chamber through a cooling inlet and exits the cooling chamber through a cooling outlet after traveling the cooling chamber's entire length. The cooling fluid removes the heat generated by the radiation and allows the useful emission to be optimized.

  • Patent number: 4937490
    Abstract: An apparatus for producing high intensity radiation has electrodes positioned within an elongated cylindrical arc chamber across which an arc discharge can be established. Liquid is injected into the arc chamber to produce a vortex motion therein to form a cylindrical liquid wall adjacent to the chamber, which constricts the arc by cooling an outer periphery thereof. Gas is injected into the arc chamber to produce a vortex motion adjacent the cylindrical liquid wall. An exhaust structure actively exhausts the liquid and gas from the arc chamber to reduce turbulence and restriction of fluid. This permits attainment of higher flux densities in the arc, and/or extension of electrode life. Preferably, the liquid and gas are exhausted actively by means of an ejector pump which ejects pressurized liquid into the gas and liquid leaving the arc chamber.
