Abstract

Selon l'invention, une structure de douille (1902) est disposée dans un ou plusieurs éléments de lampe détachables (1900) d'une lampe, dans laquelle structure de douille la chaleur produite par la source de lumière ou les sources de lumière de l'élément de lampe est conduite. La structure de douille conduit bien la chaleur ou a des parties qui conduisent bien la chaleur. La lampe a une formation (1903), qui a au moins partiellement la forme de la forme externe de cette structure de douille, de telle sorte que la structure de douille peut être disposée dans cette formation. A l'aide de cette formation, la structure de douille est amenée à proximité d'une substance de refroidissement transportée par un agencement de refroidissement (1906, 1901) de la lampe, ce par quoi le refroidissement est rendu plus efficace. La substance de refroidissement est amenée dans la formation, de telle sorte que la substance de refroidissement refroidit la structure de douille, qui, par exemple, à un trou (1906), à travers lequel passe la substance de refroidissement. Par conséquent, la formation a un agencement d'étanchéité (1904), lequel empêche la substance de refroidissement de sortir de la formation quand l'élément de lampe n'est pas en place dans la lampe. L'agencement d'étanchéité est configuré de façon à s'adapter dans la formation, et il recouvre les surfaces de la formation. L'agencement d'étanchéité peut avoir des ouvertures, ce par quoi, lors de la rotation de l'agencement d'étanchéité en place dans la formation, il peut être disposé dans les positions dans laquelle les ouvertures sont dans l'agencement de transport pour la substance de refroidissement ou dans laquelle les parois de l'agencement d'étanchéité ferment le passage de la substance de refroidissement.
