  • High intensity arc discharge lamp having clip member to secure base to outer lamp envelope
    Patent number: 5550422
    Abstract: A modified base construction for a high intensity arc discharge lamp is described enabling a single piece screw type conductive base member to be directly secured to the outer lamp envelope. The simplified base construction employs a conductive clip physically attached to the outer lamp envelope which provides a locking engagement between the assembled lamp parts.

  • Horizontal burning metal halide lamp
    Patent number: 5539271
    Abstract: An improved arc tube for a horizontal burning metal halide arc discharge lamp is disclosed to avoid light output fluctuations which otherwise occur during lamp operation. The improved arc tube construction employs opposing planar pinch seal regions which are angularly displaced with respect to each other while further positioning the opposing discharge electrodes below the longitudinal central axis of the arc tube member.
