ABSTRACT:
The light emission of a gas-discharge lamp is controlled effectively by the action of a cooling organ making use of a Peltier element having its cold side thermally connected with a portion of the wall of the lamp and having its hot side thermally connected with means for discharging heat to the ambient, together with means for sensing the temperature at said wall portion and for regulating correspondingly an electrical current to the Peltier element.
