20150041713 | INTERMETALLIC COMPOUNDS FOR RELEASING MERCURY - Materials, compounds, systems, and methods of dosing fluorescent lamps to reduce run-up time by improving mercury release rates. A pellet comprises a core and a coating on at least a portion of the surface of the core, the coating being formed from a powder of one or more intermetallic compounds comprising mercury. A method comprises providing a core and forming a coating on at least a portion of the surface of the core with a material comprising one or more intermetallic compounds comprising mercury and a metal selected from the group consisting of silver, copper, tin, zinc, bismuth, gold, platinum, palladium, nickel, manganese, and titanium. | 02-12-2015 |
20120194092 | DISCHARGE LAMP WITH LONG LIFE - Methods and apparatuses for starting a discharge lamp are disclosed. In some embodiments, a lamp has an outer envelope connected at one end to a base and enclosing multiple double-ended arc tubes. Each arc tube is electrically connected at one end to an electrical lead positioned proximate the base of the lamp and at the other end to an electrical lead positioned proximate the distal end of the envelope. A voltage pulse is applied to the electrical lead positioned proximate the distal end of the envelope. Random starting of the arc tubes may thus be effected so that each arc tube is about equally likely to start, promoting uniformity of arc tube usage and long lamp life. Multiple arc tubes may be bulbous and staggered in axial displacement for space efficiency, and a diffusing shroud may improve optical characteristics. A heat barrier may facilitate fast restrikes. | 08-02-2012 |
20100327729 | INFRARED HALOGEN LAMP WITH IMPROVED EFFICIENCY - Methods for improving the efficiency of infrared (IR) halogen lamps and IR halogen lamps having improved efficiency are disclosed. In a method of aligning a filament in a lamp body, the lamp body having the filament therein is rotated, and tubular end portions are heated and necked down which may assist in positioning the filament within the lamp and reduce end losses. IR halogen lamps formed from glass tubes having an OD less than 5 mm are also disclosed. The reduced diameter of the glass tubing increases the surface area for IR energy reflection and reduces end losses. Spuds or beads may be used to position the filament within the lamp. | 12-30-2010 |
