A compact fluorescent lamp (CFL) including an insulating barrier between heat sources and heat sensitive components. The heat sensitive barrier is in the form of an insulative layer of cement applied between the heat generating components of the CFL and one or more heat sensitive components of the CFL. The cement can also fix or secure various components within the lamp thereby eliminating the need for some or all of the support structure of a conventional CFL.

Thermal barrier and parts fixing in compact fluorescent lamps

A lamp assembly having a CFL light source includes an outer envelope received around the light source. The outer envelope includes a first enlarged portion dimensioned for receipt about the light source and a second narrowed portion adapted for connection with a lamp base. A platform receives a first end of the CFL light source and supports the CFL within the envelope, the platform including a tapered perimeter portion dimensioned for abutting engagement with an interior surface of the envelope.

Holder for integral compact fluorescent lamp with outer bulb

The invention relates to the discharge tube of a compact fluorescent lamp which discharge tube, being sealed hermetically and provided with appropriate fill, comprises at least two tube portions connected with each other, and electrodes are placed at the ends of the first and last tube portions, and lead wires protrude through the glass wall of the discharge tube to the electrodes. The invention also relates to a method for closing at least one of the tube portions forming a part of the discharge tube of a compact fluorescent lamp. The essential feature of the discharge tube according to the invention is that at least one of these tube portions is closed by a curved surface having tangents which, starting from the axis of the tube portion and extending to the cylindrical wall thereof, make a monotonously decreasing angle with the axis of the tube portion.
