  • Publication number: 20090079316
    Abstract: An outer envelope for accommodating at least one light-emitting body and a control gear with electrical components is suggested, the outer envelope comprises a wall at least partially of a glass material, in which the glass wall of the outer envelope is covered with a coating of powder varnish of poly-ester-blocked isocyanate for uniform spherical luminous intensity distribution, protecting the envelope against mechanical shocks and providing for shatter containment. A lamp with an outer envelope for accommodating at least one light-emitting body and a control gear with electrical components is also suggested. An improved compact fluorescent lamp comprises a discharge tube arrangement, a ballast circuit, a base and a substantially bulb-shaped outer envelope.

  • Patent number: 6906460
    Abstract: A device for retaining a mercury source in the discharge space of a low-pressure discharge lamp is disclosed. The mercury source retaining device comprises a holder, which has an inner space communicating with the discharge space and a receiver opening for receiving a mercury source. The retaining device further comprises resilient clamping means for clamping the holder in a tubular space segment of the discharge space and resilient retaining means at least partially blocking the receiver opening. The resilient retaining means are adapted for allowing a passage of the mercury source in a direction towards the inner space of the holder, but block the movement of the mercury source through the receiver opening in a direction out of the holder.

  • Patent number: 6628054
    Abstract: A lamp base in combination with a low pressure discharge lamp is provided. The low pressure discharge lamp comprises a glass envelope which has an end portion and an axis. A stem is melted into the end portion of the envelope in a gas-tight manner in order to form a seal region. The stem is mounted with an electrode and includes a current in-lead which is connected to the electrode. The lamp base comprises a metallic base shell which is fitted to the seal region. A resilient insert is disposed substantially in the base shell. The resilient insert embraces the seal region ant least partly, and fits resiliently to an interior surface of the base shell. The insert has means suitable for positioning the lamp base in cooperation with further means formed on the surface of the seal region.
