Abstract: The lamp cooling system uses a cooling gas stream directed onto the lamp flask (18b), while the latter is rotated at a rate of between 650 and 950 rotations per min. Pref. the lamp flask (18b) is spherical, with a dia. of 3.048 cm. Jets (30a, 30b) spaced around its surface are used to provide the cooling gas stream. The rotation is effected via an attached shaft (18a) coupled to an electric motor. USE/ADVANTAGE - Plasma lamp stimulated by microwaves or HF waves to stimulate emission in UV, visible, or IR range, preventing overheating to extend working life.
