Abstract: A motorized bracket is intended to receive, in a support, a video projector and having a base, a first arm and a second arm. The first arm is connected to the base at a first motorized rotation axis. The second arm is connected to the first arm at a second motorized rotation axis and the second arm is connected to the support at a third motorized rotation axis. The motorized rotation axes each consist of a motor coupled to a geared motor assembly in direct engagement with the arm or the support that is to be controlled.

Abstract: A projector including a plurality of laser light sources and a projection engine fitted at the inlet with an integrating tunnel in which these laser light sources are connected in an offset manner to the projection engine through a bundle of optical fibres including a plurality of inlets and a single outlet, the bundle of fibres being fused at each of the inlets and the single outlet to eliminate the inter-fibre spaces therefrom, the inlets, fused in this way, of the bundle of fibres, being disposed at the focal planes of the outputs of the laser light sources and the single outlet, fused in this way, of the bundle of fibres, being placed in direct contact with the integrating tunnel via a homogenising plate.

Abstract: In a light projector including a laser diode module suitable for forming a light bundle of color and dimensions that are determined from parallel light beams from each of the laser diodes in the module, there is provided a light-tight box, an optical system constituted by an off-axis parabolic mirror for receiving the light bundle and for focusing it, after reflecting it in a perpendicular direction onto the inlet of a sole outlet optical fiber of the box.

Abstract: A diode lighting module comprising both a diode matrix mounted on a support plate and heat dissipator means for dissipating the heat given off by the diode matrix, includes a metal plate having an outside face in contact with the support plate and an inside face supporting a cellular metal foam including a plurality of calibrated holes passing through each cell in two perpendicular directions, and a vessel-forming box filled with the cellular metal foam and for which the metal plate constitutes a lid. The box has inlet and outlet orifices passing through the box to receive a cooling liquid, and a separator defining two separate cooling fluid flow zones in the cellular metal foam, a cooling fluid feed zone and a cooling fluid discharge zone, with passage from one of the zones to the other taking place through a cutout in the separator.

Abstract: A projector includes a diode light source for a projector. The light source comprises at least first, second, and third diode matrices respectively delivering at least first, second, and third light bundles at separate wavelengths and of determined dimensions. A first dichroic plate forms a first combined light bundle CLC1 from the first and second light bundles, a second dichroic plate forming a second combined light bundle CLC2 from the first combined light bundle and the third light bundle, and an off-axis parabolic mirror for receiving the second combined light bundle CLC2 and focusing it on a determined focal point forming an inlet point for a single optical fiber.
