Abstract

La présente invention se rapporte au domaine technique de l'éclairage de scène et concerne un système de dissipation de chaleur pour une lampe à décharge gazeuse. Le système comprend structurellement un réflecteur parabolique, un corps de lampe disposé à l'intérieur du réflecteur parabolique, un dispositif d'alimentation en air et un dispositif de guidage d'air en communication avec le dispositif d'alimentation en air. Le dispositif de guidage d'air comprend un canal d'air de réflecteur parabolique et un mécanisme de changement de canal d'air. Le canal d'air de réflecteur parabolique délivre de l'air le long du corps de lampe d'un côté du réflecteur parabolique vers l'autre côté du réflecteur parabolique pour être refoulé hors du réflecteur parabolique. Le mécanisme de changement de canal d'air change une direction de guide d'air dans le canal d'air de réflecteur parabolique, de sorte que le canal d'air de réflecteur parabolique soit modifié dans une direction circonférentielle du réflecteur parabolique. Le système de dissipation de chaleur pour lampe à décharge gazeuse selon l'invention est capable de changer le canal d'air dans une direction axiale, de sorte que de l'air puisse être distribué à toutes les surfaces du corps de lampe, et par conséquent, le corps de lampe a une distribution de température uniforme sur la même section transversale dans une direction perpendiculaire à un axe optique. De plus, l'air forme un écoulement vers le bas selon l'attraction gravitationnelle, ce qui refroidit uniformément toutes les surfaces, réduit les différences de température sur les surfaces extérieures du corps de lampe, et réduit la probabilité de détérioration de l'ampoule.
