摘要:
A compact fluorescent lamp includes an inverted compact fluorescent light source housed within an outer envelope. Locating the first and second ends of the coiled CFL source positions the electrodes within a substantially spherical outer envelope at a location remotely spaced from the ballast compartment. In this manner, only small diameter first and second lead wires that mechanically and electrically engage the electrodes pass through small dimensioned passages in a separation member in the outer envelope cavity. This substantially reduces the thermal stress on the components.

An electric lamp comprises an inner assembly including a light source and a control gear circuit. An outer envelope encloses the light source and at least a part of the control gear and has a predetermined wall thickness and an end portion. The outer envelope is comprised of two parts separated along a circumferential line. The two parts of the envelope are connectable and sealable to form a uniform outer envelope with a seal region. The seal region has a wall thickness and is merged in a surface portion of the two parts of the envelope so that the surface unevenness of the seal region is not greater than 0.5 millimeters, and the maximum difference of the wall thickness of the seal region with respect to the wall thickness of the outer envelope is not greater than 0.3 millimeters.A method for manufacturing an electric lamp as described above is also disclosed. During connecting, and sealing the two parts of the envelope by a welding process, the two parts are brought into a contacting position and compressed further by a first axial distance; and then the two parts are pulled apart from each other by a second axial distance in order to merge the seal region in a surface portion of the two parts, wherein the second axial distance is larger than the first axial distance.

A bulb-shaped outer envelope for accommodating at least one lamp including a light-emitting body and a control gear is disclosed. The envelope has a substantially spherical section for receiving the light-emitting body, and an elongated end section for receiving at least a part of the control gear components. The elongated end section is provided with a neck section. A substantially tubular neck-extension portion connects to an inner surface portion of and protruding from the neck section. The neck-extension portion is suitable for accommodating a remaining part of the control gear components. In a method for the manufacture of a glass outer envelope, a flare that is normally used in the manufacture of incandescent lamps is turned around by 180°, put into a skirted bulbous envelope, melted into the envelope while the skirt is detached and the flare is formed into a neck-extension portion. A self-ballasted compact fluorescent lamp with the bulb-shaped outer envelope is also disclosed. A part of the ballast components are disposed in the neck-extension portion of the outer envelope.

Plastic housing and base construction, especially for compact fluorescent lamps and operating units thereof comprising a housing (1) which is a cup-like body and a base (2) having a metal base shell (26) and at least one metal central (3) or end contact part (4, 5). The base shell (26) is electrically insulated from the central (3) or end contact parts (4, 5). The base (2) also includes a plastic insert body (20) which is open at its upper end and closed at least partially at its lower end. The diameters of the plastic insert body (20) decrease in at least one step and it has a cylindrical or slightly conical mantle portion (24) in the region of its upper end. The base shell (26) includes a thread-free opening portion (27) the inner diameter of which fits to the mantle portion (24) of and is pulled over and fixed to the plastic insert body (20). The metal central contact part (3) or each end contact part (4, 5) is fixed to the lower end of the insert body (20) which has a rim (22) at its upper end for connecting to the housing (1). The housing in turn has a connection end (11) for receiving the insert body (20).

The discharge lamp has a discharge tube filled with a fill gas and sealed in a gas-tight manner and a cap part made to be suitable for connection to a socket. This cap part has a housing made by a shell and a closing member fixed thereto, and electrical contact components. The shell has openings for receiving the end portions of the discharge tube legs into the housing and the shell is made to be suitable for supporting the discharge tube mechanically. The electrical contact components are embedded in the housing and connected in the inner space of the housing to the electrodes of the discharge lamp and protrude from the cap part. The cap part contains mechanical support component(s) for fixing the discharge lamp in the socket. The mechanical support component(s) forms (form) a part of the shell and the portions of the electrical contact components protruding from the cap part are placed in an outwardly open indentation defined by an indented plate portion of a bordering plate of the cap part, preferably of the base plate of the closing member.
摘要:
A lamp assembly provides both instant light through use of an incandescent/halogen lamp source and an energy saving type light provided by a compact fluorescent lamp source. Both light sources are enclosed within a common envelope or outer bulb. The sensor member monitors a temperature of the cathode and mercury reservoir of the compact fluorescent lamp source in order to determine when to terminate power to the incandescent lamp source.

A compact fluorescent lamp comprises a discharge tube arrangement with at least one discharge tube. The tube is formed of glass, encloses a discharge volume filled with a discharge gas and has a fluorescent phosphor coating disposed on the inner surface of the tube. The tube forms a continuous arc path and has electrodes disposed at each end of the arc path. The lamp also comprises a ballast circuit connected to the electrodes by lead-in wires and to a supply voltage by lead-out wires for controlling the current in the tube. A bulb shaped outer envelope comprises a substantially spherical portion, which encloses the tube arrangement and an elongated end portion, which encloses the ballast circuit. The end portion of the outer envelope has a neck portion with an open end on a base side for receiving a base shell. The open end of the neck portion is closed and terminated by a closing and neck reinforcing means of a material compatible with the material of the outer envelope, which has a substantially circular opening. The lead-out wires are led through the substantially circular opening to a base shell for connecting said lamp to said supply voltage through a socket.A method for manufacturing a compact fluorescent lamp as described above is also disclosed. In the proposed method the open end of the elongated portion of the outer envelope is closed and terminated with a closing and neck reinforcing means comprising a substantially circular opening for leading through the lead-out wires.
