  • Patent number: 8833105
    Abstract: A method for making a vacuum insulated glass window assembly is provided in which an exposed end of a pump-out tube of a vacuum insulated glass window assembly is sealed using a laser that is applied to the end of the pump out tube in controlled sequential manner as opposed to a short duration, high-powered application of a laser. In particular, a method is disclosed in which a multiphase sequential variable power application of laser energy to an exposed end of a pump-out tube for controlled exposure times and decreasing laser trace diameters produces a more controlled melting of the tube glass to reduce or eliminate undesirable outgassing that may occur during a high-power short duration exposure of laser energy to the end of the pump-out tube to seal the tube.

  • Patent number: 8702465
    Abstract: The manufacture of an electrodeless bulb involves one end of a tube closed off, and a first neck is formed in the tube close to the closed end. A second neck is formed in the tube, close to the still open end; a metal halide pellet of known size is dropped into the tube and the tube is evacuated. With the vacuum being maintained heat is applied to the closed end, causing the metal halide pellet to sublime and with it the impurities. The impurities are drawn off, the vacuum being maintained and the metal halide condenses in the tube between the necks. Once the tube is cool, the evacuation is discontinued and the tube is refilled with noble gas and the quartz tube is sealed off at the second neck.

The ceramic burner comprises a discharge vessel enclosing a discharge space that is provided with an ionizable filling comprising one or more halides. The discharge vessel comprises a ceramic wall arranged between a first and a second end portion. The first and the second end portion are arranged such that current supply conductors are passed through the end portions to respective electrodes arranged in the discharge space for maintaining a discharge. The ceramic wall of the discharge vessel comprises a tube for introducing the ionizable filling into the discharge vessel during manufacture of the ceramic burner. The tube projects from the ceramic wall and is provided with a gastight seal. The effect of using the tube is that it enables the gastight seal to be arranged away from the ceramic wall of the discharge vessel at a projecting end of the tube.

  • Publication number: 20120040585
    Abstract: A method of assembling an airtight LED light bulb has the steps of: connecting a stem device with an LED device, drying the LED device, connecting the stem device with a bulb envelope, extracting air in the bulb envelope via a pipe, filling the bulb envelope with nitrogen or inert gas via the pipe, sealing an opening of the pipe which is located outside the bulb envelope to make the bulb envelope completely airtight and connecting a cap with the bulb envelope. Because the bulb envelope is airtight, moisture in the environment can not damage the LED device, and the steps of extracting air in the bulb envelope via the pipe and filling the bulb envelope with nitrogen or inert gas via the pipe are feasible. Consequently, the LED device will not easily be oxidized or dampened, so the lifespan of the airtight LED light bulb can be prolonged.

  • Patent number: 8072139
    Abstract: Disclosed is a method for sealing a light-emitting device wherein formation of air bubbles in a light-emitting device module can be prevented by performing no gelation after fitting of a cover member. This method also enables to seal a light-emitting device by using a gel sealing material composed of a gel precursor which uses a solvent. Also disclosed is a light-emitting module formed by such a sealing method. In this method for sealing a light-emitting device, gelation of the gel precursor of a gel sealing material is performed before placing the precursor on the light-emitting device, and thus no gelation is necessary after fitting of a cover member. Consequently, a gel precursor having high viscosity that is difficult to be used in an injection method can be used in this method. Furthermore, a substance which requires use of a solvent can be used as a gel precursor of a gel sealing material.

  • Patent number: 7524229
    Abstract: A method of manufacturing a gas discharge tube by closing an opening of a glass tube by forming a glass layer with outer peripheral shape identical to the outer peripheral shape of the glass tube on an end face of the glass tube. An open end face (opening) of the glass tube is pressure-welded to a dry film containing a low melting point glass powder and a binder resin, and then the glass tube is lifted up to transfer the dry film for closing the opening to the end face of the glass tube. A phosphor support member is inserted into the glass tube from a side opposite to the end face and then an end of the phosphor support member is caused to adhere to the dry film. The binder resin is burnt off, and the dry film is vitrified to produce a low melting point glass layer.

Heating and melting from a side is carried out. The opening end of the glass tube is connected to a piping passage component for discharging air and introducing an inactive gas through a rotatable magnetic fluid seal unit. Secondary welding is carried out with the rotation of the glass tube around an axis. The glass tube rotated with respect to secondary side heater is uniformly heated, molten and softened circumferentially, and welded along the arc tube body outer periphery.
