High luminance electrodeless projection lamp |
| abstract |
An Electrodeless High Intensity Discharge (EHID) lamp for projectionnapplications. The lamp has a small (nominal dimensions: 2mm I.D., 3mm O.D., 6mmninternal length) capsule, which is constricted in a mid-portion thereof. Thenconstriction squeezes the plasma within the capsule and provides a higher powerndensity. This in turn produces a higher luminance in the center of the arc. This focalnpoint of the projection system is constant over the life of the lamp, owing to the factnthat the system is electrodeless. The arc tube or capsule is thickened in the vicinity ofnthe constriction to permit heat transfer through the vitreous silica (commonly callednquartz). The thickening carries the heat away from the now hotter mid-portion area.nThis thickening cools by virtue of increasing the thermal conduction through thenglass. |
