Abstract

A high-pressure discharge lamp has a discharge vessel that is enclosed, with an interspace, by an outer bulb. The end of the outer bulb is provided with a lamp cap. The lamp has an ignition circuit including a series connection of a glow starter and an ohmic impedance. The ohmic impedance is formed by a halogen incandescent lamp. The mutual orientation of the glow starter and the ohmic impedance is such that heat produced by the ohmic impedance is at least partly intercepted by the glow starter.
