A xenon arc lamp for a motion picture projector is cooled by providing the anode end of the lamp with a shroud that forms part of a support for that end of the lamp. Cooling air flows into the shroud along the support arm and enters the shroud through a slot in its side wall. The shroud provides an annular air space around the anode end of the lamp and has an annular air outlet through which the cooling air leaves as a "sheet" of laminar air flow which tends to adhere to the surface of the bulb, thereby providing precise cooling. In this way, arc instability is avoided or minimized, while lamp life is extended.

Méthode de refroidissement d'une lampe à arc au xénon destinée à un projecteur de cinéma, dans laquelle l'extrémité anodique de la lampe est dotée d'un carénage qui fait partie d'un support pour cette extrémité de la lampe. L'air de refroidissement entre dans le carénage le long du bras de support, par l'entremise d'une fente dans sa paroi latérale. Le carénage assure une poche d'air annulaire autour de l'extrémité anodique de la lampe et comporte une sortie d'air annulaire par laquelle l'air de refroidissement sort sous forme d'une « feuille » d'écoulement d'air laminaire, qui tend à adhérer à la surface de l'ampoule, assurant ainsi un refroidissement précis. De cette façon, on évite ou minimise l'instabilité d'arc, tout en prolongeant la durée de vie utile de la lampe.
