Thermal barrier and parts fixing in compact fluorescent lamps

摘要

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.

主权项

1. A lamp assembly comprising:
a lamp base having a compartment; a lamp source supported by the lamp base; a power control module received in the lamp base compartment and operatively connected to the lamp source; and an insulative cement layer surrounding the lamp source and fixing the lamp source to the lamp base, the insulative cement layer extending between the lamp source and the power control module across substantially an entire cross section of the lamp base and having a thickness to insulate the power control module from heat generated by the lamp source.
