Gas discharge lamp

A mercury discharge lamp includes an amalgam for controlling the mercury vapour pressure within the lamp, the amalgam being selected and positioned within the lamp to provide a substantially optimum vapour pressure of mercury at the temperature of the amalgam corresponding to the maximum rated operating power of the lamp. The optimum vapour pressure is close to a minimum (B) at the temperature corresponding to maximum operating power, and adjacent a region (D) of steeply rising mercury vapour pressure with falling temperature.

Low-pressure mercury vapor discharge lamp with amalgam capsule having amalgam chamber

An amalgam capsule (16) for a low-pressure mercury vapor discharge lamp (1) has a closed end and an opposing end with an opening (21) to allow passage of mercury vapor between the amalgam plug (18) and the discharge space (3) of the lamp (1). A glass rod (19) placed in the capsule (16) restrains movement of the amalgam plug (18), and projections (20) in the inner wall of the capsule (16) restrain movement of the glass rod (19). The presence of the amalgam capsule (16) in the discharge space (3) enables highly-loaded, substantially temperature-independent operation of linear fluorescent lamps such as T8 lamps.

Device with a liquid-cooled high pressure vapor discharge tube.

Single unit compact fluorescent lamp

The compact fluorescent lamp is supplied directly from the mains via an electronic circuit fitted in the base (4) of the lamp itself. The fluorescent tube is wound in a coil (1) and enclosed in a protective outer sleeve (2). The outer sleeve is held clear of the fluorescent soil by spacers (3) distributed along the length of the lamp. The lamp is cooled by allowing air to enter the interior of the protective outer sleeve through holes (8) formed at the edge where the outer sleeve joins the lamp base (4). The equalisation of pressures inside and outside the outer sleeve improve the mechanical strength of the outer sleeve, making handling safer.
