Abstract

The present invention relates to a flat wall-mounted sun-tracking and light-guiding device with built-in sensors, which comprises a sun-tracking and light-guiding member, a sun-tracking controller, a light concentrator, and a switchable light emitter. The sun-tracking and light-guiding member owns the function of tracking the sun and is coupled to the sun-tracking controller. The light concentrator faces the sun and is used for concentrating the sunlight. In addition, the light concentrator is connected with the sun-tracking and light-guiding member. The light concentrator includes a light-guiding optical fiber, which is used for guiding the concentrated sunlight. Besides, the switchable light emitter is connected with one end of the light-guiding optical fiber. The switchable light emitter can be disposed indoors or on plant chambers for lighting the interior or plants using the sunlight guided by the light-guiding optical fiber.

First claim

What is claimed is:

1. A wall-mounted sun tracking and light guiding apparatus, comprising:
a sun-tracking controller;
a sun-tracking and light-guiding member, coupled to said sun-tracking controller, including an east-west driving mechanism and a south-north driving mechanism, said east-west driving mechanism disposed on a base, said south-north driving mechanism disposed on said east-west driving mechanism, and said sun-tracking controller controlling the driving of said east-west driving mechanism and said south-north driving mechanism;
a light concentrator, connected with said south-north driving mechanism, and including a light-guiding optical fiber and a plurality of light-sensing optical fibers; and
a switchable light emitter, including a light-emitting plate and a plurality of photosensors, said light-emitting plate connected with one end of said light-guiding optical fiber, and said plurality of photosensors connected with one of end of said plurality of light-sensing optical fibers.

2. The wall-mounted sun tracking and light guiding apparatus of claim 1 , wherein said sun-tracking controller includes one or more microprocessor.

3. The wall-mounted sun tracking and light guiding apparatus of claim 1 , wherein two or more east-west driving rods and an east-west driving-mechanism platform pass through said east-west driving mechanism.

4. The wall-mounted sun tracking and light guiding apparatus of claim 3 , wherein said two east-west driving rods are connected between said east-west driving mechanism and said east-west driving-mechanism platform, and one of said two east-west driving rods is combined and moved linkedly with an east-west gear.

5. The wall-mounted sun tracking and light guiding apparatus of claim 4 , wherein said east-west driving mechanism includes an east-west motor frame; said east-west motor frame includes an east-west geared DC motor; and said east-west gear is connected with an axle center of said east-west geared DC motor.

6. The wall-mounted sun tracking and light guiding apparatus of claim 1 , wherein two or more south-north driving rods and said light concentrator pass through said south-north driving mechanism.

7. The wall-mounted sun tracking and light guiding apparatus of claim 6 , wherein said two south-north driving rods are connected between said south-north driving mechanism and said light concentrator, and one of said two south-north driving rods is combined and moved linkedly with a south-north gear.

8. The wall-mounted sun tracking and light guiding apparatus of claim 7 , wherein said south-north driving mechanism includes a south-north motor frame; said south-north motor frame includes a south-north geared DC motor; and said south-north gear is connected with an axle center of said south-north geared DC motor.

9. The wall-mounted sun tracking and light guiding apparatus of claim 1 , wherein said light concentrator includes four light-testing optical-fiber connectors connected with said plurality of light-sensing optical fibers.

10. The wall-mounted sun tracking and light guiding apparatus of claim 1 , wherein said light concentrator further includes a light-concentrating lens having a filtering film on one surface for filtering and allowing the visible light with wavelengths between 400 and 750 nanometers to pass through.
