| 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 |
