A fluorescent lighting device includes an arc tube, an exhaust tube extending from the arc tube, and an amalgam. A resistive heater is located adjacent to at least one of the arc tube and the exhaust tube. A power supply circuit is operatively coupled with the resistive heater. When the fluorescent lighting device is switched from an OFF state to an ON state, the power supply circuit temporarily energizes the resistive heater, thereby heating the at least one of the arc tube and the exhaust tube while the resistive heater is energized, and automatically de-energizing the resistive heater after said heating.

Amalgam heater for 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.

Lamp part fixing by shape memory alloy in the discharge tube of fluorescent lamps

A hybrid lamp apparatus is presented having a primary lamp circuit with a CFL and an electronic ballast, as well as a Halogen or incandescent secondary lamp circuit with a control circuit that shuts off the secondary lamp a time period after powerup, where the secondary lamp time period varies according to the amount of time the apparatus was previously unpowered.

Hybrid lamp power circuit

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 fixed within the assembly by a fixing mechanism that spaces the lights sources from each other such that heat from one source does not negatively affect the second light source or any other portion of the assembly.
