Abstract (en)
[origin: EP0961075A2] The spotlight uses at least one energy-saving gas discharge lamp (18) and is positioned in a cooled environment, with an auxiliary lamp unit (20), e.g. a halogen lamp positioned within a common reflector housing, for providing a light and heat output during the run-up phase of the energy-saving gas discharge lamp. The light and/or heat output of the auxiliary lamp unit be reduced continually over a timed interval, initiated by a sensor detecting the overall brightness and/or temperature of the energy-saving gas discharge lamp.
