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.
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.
