The present invention relates to moving head projectors comprising a base (4,104), to which base a yoke (6,106) is rotationally connected, which yoke (6,106) is rotationally connected to a head (8,108), which head (8,108) comprises a light source placed partly inside reflective means, which reflective means forms a light beam, which light beam passes through light forming means, which light beam furthermore passes through at least one lens before the light beam leaves the projector. The object of the invention is to achieve a primarily closed moving head projector, where air from the outside is prevented from entering the inner volumes of the projector. Furthermore, the object is to prevent the use of blowing means. Cooling of all optical and electrical components in the moving head projector can take place by means of natural heat convection and heat radiation. Thus, the moving head projector can operate without active cooling means e.g. without blowing means. This automatically leads to a very low projector noise level. |
