  • Publication number: 20080265741
    Abstract: A semi-full helical luminous electronic energy-saving tube and an electronic energy-saving lamp using the tube are disclosed. The structure at the connection between the end of tube and the enclosure is a straight section. An inward bend of the straight section is achieved via an interface point between the straight section and the helical portion of the tube. The interface point includes a sharp, V-shaped 180° backward bend. By making use of the sharp inward bend, a sufficient space is left for the enclosure process.

  • Patent number: 6133676
    Abstract: A halogen bulb is composed essentially of a tubular halogen bulb having two conductive ends, a thick hollow glass envelope and a socket for holding securely the tubular halogen bulb in the thick hollow glass envelope. The thick glass envelope has a thickness ranging between about 2 mm and about 8 mm, which is made integrally or made of two component parts joined together. The thick hollow glass envelope may be provided with protuberances perpendicular to an outer surface opposite to the socket, and/or ventilation holes to reduce the temperature of the double-enveloped halogen bulb at work. The socket may be provided with one or more ventilation holes at the closed end thereof. A bracket is used inside the thick hollow glass envelope for holding the tubular halogen bulb such that the tubular halogen bulb is perpendicular to the longitudinal axis of socket.
