Abstract: A lighting device includes a series of optical waveguides, each optical waveguide being adapted to guide light rays between an entry face and an exit face, the optical waveguides being formed of a first subassembly and a second subassembly produced separately and each including a portion of the series of optical waveguides and including structural elements to retain the optical waveguides in position. The first subassembly and the second subassembly are adapted to be assembled to form the lighting device by cooperation of the structural elements, and the first subassembly includes a first structural element adapted to connect proximal ends of the optical waveguides and a second structural element distinct from the first structural element and adapted to connect distal ends of the optical waveguides.

Abstract: A lighting device includes a series of optical waveguides, each optical waveguide being adapted to enable light rays to be guided between a light entry face and a light exit face. The lighting device is formed of at least two subassemblies produced separately and each including a portion of the series of optical waveguides and structural elements for retaining the optical waveguides in position, the two subassemblies being adapted to be assembled to form the licihting device by cooperation of the structural elements. Additionally, a lighting module and a lighting system includes such a lighting device.

Abstract: The present invention involves the preparation of a pharmaceutical liposomal system in an aqueous solution which contains a substance or polymer with mucomimetic and/or mucoadhesive properties. Due to the components and characteristics of the formulation described in this present patent it can be used as a precorneal tear film substitute. This invention is included in the pharmacy and medicine areas.
