Abstract: An electrodeless fluorescent lamp includes a coil assembly which comprises a hollow ferrite core (30), and a coil (31). The core is retained on a base (32) by a coil former (34) surrounding the core. The core (30) is retained in the former (34) by a circlip (33) or by projections. The coil (31) is wound on the former. Pins (36) to which the coil is soldered connect the coil to an energising circuit.

Abstract: 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. By operating the lamp in this region, a reduction in the operating power of the lamp causes a fall in temperature and hence an increase in the vapour pressure of the mercury to effect dimming of the lamp.
