  • Patent number: 8525408
    Abstract: To stabilize the illumination fluctuation rate of a short arc type discharge lamp of the type having a pair of electrodes disposed inside an arc tube in a manner of facing each other and a hydrogen getter, by absorbing hydrogen gas in an arc tube without causing a decline in the performance of the short arc type discharge lamp arising out of a hydrogen getter, the hydrogen getter is formed of a hollow container made of a material that allows the transmission of hydrogen with a getter material sealed tightly inside the hollow container, and a holder for the hydrogen getter is held on the electrode with the hydrogen getter fixed in the holder.
    Type: Grant

  • Patent number: 8288946
    Abstract: To provide a flickerless discharge lamp which can remove hydrogen by a simple and safe means even if the lamp is a large discharge lamp with high pressure when lit, the discharge lamp has a pair of electrodes and a hydrogen getter (4) in the interior of an arc tube, the hydrogen getter (4) being formed of a container (41) made of metal which is hydrogen permeable and a hydrogen absorbent body (42) that is composed of a metal which can absorb hydrogen that is enclosed inside of the container (41) and is fixed to an inside wall of the container (41).
