Definitions

  • This invention is related to the field of daylighting. More specifically, the invention comprises a lighting system that transports daylight into the buildings which replaces or comply with the artificial lighting.
  • Fibre optic daylighting systems represent a new and innovative method of bringing direct sunlight into a building.
  • Solar collectors for passive or hybrid daylighting systems are responsible for capturing direct sunlight and channeling it into one or more optical fibres for transmission to end uses within the building.
  • Fresnel lenses When Fresnel lenses applied to solar collection, they refract incident sunlight from the entire face of the lens to a single focal point behind the opposite side of the lens. To transmit collected sunlight the exposed end of an optical fibre, or a bundle of several small fibres.
  • This system can be installed with any sun collimator that allows to use fresnel lens to focus light on fibre optics. We explain two options to describe our project well under different conditions.
  • heliostats to coliimate light which is a device that includes adjustable mirrors to keep reflecting light toward a predetermined target.
  • Modern heliostats are controlled by computers. The computer is given the latitude and longitude of the heliostat's position on the earth and the time and date.
  • the computer calculates the direction of the required angle- bisector, and sends control signals to motors, often stepper motors, so they turn the mirror to the correct alignment. This sequence of operations is repeated frequently to keep the mirror properly oriented.
  • the other option is a web-connected, intelligent sun tracker. Tracking is performed autonomously using an onboard GPS. Reflective louvers pan and tilt, redirecting sunlight where desired as a stationary beam throughout the day.
  • Collimated sun beam is being directed to the fresnel lens and focuses on an optical fibre harness to distribute sunlight to the fixtures.
  • Heliostat and sun tracker do not belong to our invention but are used to complete its function.
  • FIG.1 Isometric view of GPS sun tracker option
  • FIG.2 Isometric view of Heliostat option
  • FIG 1. shows an isometric view of one of the present solutions in an assembled state. It is configured to light up a meeting room as an example where is 3 hanging lamps at the top of the table and 4 picture lamps on the walls.
  • GPS sun tracking system (1) has louvers pan and tilt according to the data that it collects via internet to collimate coming sunlight in any direction throughout the day.
  • the fresnel lens (2) is our custom made design, designed particularly for this daylight project, thin, special lens which is made from UV cured P A like material(refractive index: 1.527nm). We measured lux levels from the surface of the lens and the focus from the same distance at noon time as 10.000lux from the surface, 18.000 lux from the focus.
  • the focusing lens (3) is used for concentrating light into fibre optics. It is a simple small piano- convex lens.
  • the high quality fibre optic cable harness is used to connect lighting fixtures to the lens system (4) and connect to light generators to the fixtures (5)(9).
  • the core material is PMMA.
  • Fiber optic led light generators (8) were used for lighting up area when there is no sunlight outside. This allows the user by adjusting the power of led generator it can be used combining with the sunlight when sunlight not sufficient.
  • FIG 2. shows an isometric view of our second suggestion which is completely same solution except heliostat system (10).
  • heliostats are big mirrors that reflects light on a specific direction in any position of sun.
  • Ability of rotating can be created by a motor which directed by a computer program that includes position data of the sun and calculates the angles that heliostat will scan periodically.

Abstract

La présente invention concerne un système d'éclairage intérieur combinant lumière du jour et lumière artificielle qui comprend: un système de poursuite solaire qui collimate la lumière solaire sur la partie supérieure d'une lentille de Fresnel puis concentre, par la lentille de Fresnel, la lumière sur une lentille plan-convexe qui se situe en dessous de la lentille de Fresnel. La lentille plan-convexe concentre le faisceau dans le système à fibres optiques qui transporte la lumière solaire dans le bâtiment et se raccorde aux appareils d'éclairage.
