  • Publication number: 20140333200
    Abstract: The geometry of a High Intensity Discharge (HID) arc tube is controlled to improve lamp color control and temperature distribution. In some embodiments, conical sections located at the transition zones near the electrodes are included to provide tunnel-like body-leg interface portions. The body-leg interface portions are shaped so as to advantageously control the temperature distribution along the internal surface of the discharge chamber wall so that it monotonically decreases resulting in a stable local cold spot location at the body-leg interface.

  • Patent number: 8823264
    Abstract: A lamp has microwave resonant body (11) of transparent quartz. The body has a central bore (16), having a sealed plasma enclosing bulb (17) inserted in it. The bulb is of quartz also and has an external diameter which is a close fit in the bore. The bulb itself is of drawn quartz tube (18) and as such has a smooth internal bore (19). End caps (20) are fused to the tube and encapsulate a charge of a material excitable to form a light emitting plasma in the bulb when microwaves are fed into the body via an antenna (7) in a bore (21) in the body. The body is sized to establish resonance within the Faraday cage in the body (11), bulb (17) and fill containing void (22) within the bulb. There is negligible gap between the bulb and body, whereby they can be regarded as one for resonance purposes. The bulb is fixed in the body by welds (23).

    Abstract: 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.
