ABSTRACT:
The invention relates to a gas-and/or vapor discharge lamp which is provided with a discharge tube and with a heat shield.
The heat shield is connected to a bimetal element of the lamp such that, when the temperature of the discharge tube is raised (or lowered) the heat shield is further removed from (or moved towards) the discharge tube. Accordingly the lamp reaches its operating condition rapidly after starting and in the operating condition fluctuations in the temperature are very small.
