| 20090253335 | TUBULATION-FREE GAS FILLED ELECTRODE OR LAMP - A method of making a tubulation-free gas filled electrode or lamp having the steps of providing a glass or quartz tube having a first end and a second end opposite the first end; inserting a cathode into the first end; crimping the first end thereby securing the cathode and making the first end airtight; securing a solid plug inside the tube second end but leaving a gap between the plug and tube through which gas can pass; evacuating air from inside the tube by drawing it through the second end past the plug; charging the tube with a gas; and sealing the plug gap to make the second end airtight. | 10-08-2009 |
| 20110183576 | METHOD OF PACKAGING ELECTRON EMISSION DEVICE - An electron emission device including a first substrate, a second substrate, a gas, a sealant, and a phosphor layer is provided. The first substrate has a cathode thereon, and the cathode has a patterned profile. The second substrate is opposite to the first substrate and has an anode thereon. The sealant is disposed at edges of the first substrate and the second substrate to assemble the first and second substrates. The gas is disposed between the cathode and the anode and configured to induce a plurality of electrons from the cathode, wherein the pressure of the gas is between 10 torr and 10 | 07-28-2011 |

| 20100003885 | High intensity discharge lamps, arc tubes, and methods of manufacture - The present application discloses high intensity discharge (“HID”) lamps, arc tubes, and methods of manufacture. The application relates to HID lamps, arc tubes, and methods of manufacture wherein a precise amount of fill gas may be contained in the light-emitting chamber of the arc tube so that the pressure of the fill gas contained in the arc tube at substantially room temperature may be precisely controlled at pressures greater than about one-half atmosphere. | 01-07-2010 |
| 445040000 | With heating, e.g., to outgas | 2 |
| 20100197188 | FURNACE AND METHOD FOR PRODUCING A DISCHARGE LAMP - The invention relates to a furnace ( | 08-05-2010 |
| 20130040529 | Electrode-less Incandescent Bulb - 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. | 02-14-2013 |

| 20090298376 | METHOD FOR LED-MODULE ASSEMBLY - A method for LED-module assembly comprising the steps of providing a base portion with a base inner surface and a cover with a cover inner surface which together define a module interior, the cover having at least one opening therethrough; putting a sealing member into the module interior; positioning an LED lens into the cover opening; aligning an LED emitter and the LED lens within the module interior; sealing the module interior by securing the base portion with respect to the cover. The LED emitter is powered for imaging of the LED module to test light-output characteristics. A specific type of the LED lens is selected and its type and orientation are verified. The step of vacuum testing checks for water-air/tightness of the sealing of LED-module interior. A central database provides assembly and testing parameters to automated tool(s) performing each particular step. Each LED module includes a unique machine-identifiable module-marking with which the data related to each individual LED module is associated and stored in the central database. | 12-03-2009 |
| 20120040585 | Method of Assembling An Airtight LED Light Bulb - 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. | 02-16-2012 |
