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

The present disclosure relates to a lamp part fixing device and method for lamp components made of shape memory alloy. The device includes a main body that carries, for example, a main or auxiliary amalgam, getter, etc. located at a desired position within a discharge tube of a fluorescent lamp. For example, the amalgam can be advantageously located at preselected axial locations and/or within a diffusion path. The main body is configurable between a first configuration and a second configuration. The first configuration allows the mount to move within the discharge tube when the shape memory alloy is below an alloy transition temperature. The second configuration of the main body allows for controlled placement and immobilization of the device within the discharge tube when the shape memory alloy is raised above the alloy transition temperature. The device is shaped in a generally planar or non-planar configuration.
