Definitions

• the present invention refers to a mobile lighting system, in particular a mobile lighting system of a commercial and/or residential environment .
• solar lighting is an essential aspect to give value, usability and functionality to a room, both in a commercial and in a residential environment. In environments where natural light is not sufficient to carry out domestic or work activities, it is necessary to intervene with artificial light.
• ducted lighting systems are known in the art which allow natural light to be transported to the darkest areas of the rooms, improving the habitability and healthiness of rooms without windows or skylights.
• ducted lighting systems are composed of a capturing element outside the building, a duct for the transport of light radiation and an emission element for the distribution of light in the environment.
• Another object of the present invention is providing a mobile lighting system as mentioned above, capable of following the path of the natural light source throughout the day, providing optimal lighting even when the light source is partially or totally obscured, or in the extreme hours of the day (sun low on the horizon) by conveying the light rays inside the conduit that would otherwise pass through the capturing dome.
• a final object is automatically providing artificial lighting of a commercial and/or residential environment on the basis of brightness specifications requested by the user.
• FIG. 1 shows a sectional view of a preferred embodiment of the system according to the present invention
• FIG. 2 shows a sectional view of FIG. 1;
• FIG. 3 shows a sectional view of a second embodiment of the system according to the present invention
• FIG. 4 shows a sectional view of FIG. 3.
• a mobile lighting system 1 is designed to provide lighting in a commercial and/or residential environment on the basis of brightness specifications requested by the user by means of a device 10 for capturing the luminous flux emitted by a natural light source 2 from sunrise to sunset, even in a partially and/or totally obscured condition of the natural light source 2.
• the system 1 according to the present invention is equipped with:
• a lenticular diffusing element 8 for example a lenticular or microprismatic diffusing ceiling light made of compact polycarbonate or methacrylate, connected at the top on the lower perimeter of the cylindrical duct 7 designed to favor the irradiation of the solar luminous flux coming from the cylinder duct 7 in the commercial
• the capturing device 10 consists of: a parabola element 4 equipped with a reflecting surface 4a, and a lower end connected with at least one rotary means 20; the reflecting surface 4a is internally composed of suitably shaped highly reflective aluminum sheets, preferably treated with Physical
• Vapor Deposition technology which allows depositing a system of optical layers composed of ultra-reflective silver and protected with silicon and titanium oxides, in order to obtain total reflection values higher than 98%, designed to favor the reflection on the internal surface of the cylindrical duct 7 of the solar luminous flux coming from the natural light source 2;
• the rotary means 20 consisting of: an electronic processing element 11, a mechanical movement element 12, a solar panel element 5 for feeding the rotary means 20, this rotary means 20 designed to induce a movement of the parabola element 4, by means of the mechanical movement element 12 and by means of the electronic control processed by the electronic processing element 11, favoring the optimal positioning of the parabola element 4 according to the position of the natural light source 2; and an electrical energy storage element 6, connected to the rotary means 20 designed to induce electrical energy required by the user.
• a second embodiment of the system is described, as shown in FIG. 3 and 4 by way of a non-limiting example, equipped with a cylindrical duct 7 characterized by a lower height dimension than the first embodiment, designed to allow adapting and inserting the system in a plurality of commercial and/or residential environments with different technical and construction requirements.
