Natural light guiding system used for plant cultivation

1. A natural light guiding system used for plant cultivation, comprising a chasing light and collecting light device and at least one lighting device connected to the chasing light and collecting light device, wherein the at least one lighting device includes:

a hollow lampshade, wherein the cross-sectional area of the lampshade is gradually reduced relative to a height thereof, a top plate mounted to a top of the lampshade and having at least one through hole defined therein; the lampshade being a pyramid structure and assembled by multiple modular trapezoidal plates, each trapezoidal plate having two bevel edges respectively having a connecting flange formed thereon, wherein every two adjacent connecting flanges abut and is secured to each other;

at least one optical fiber connected to the chasing light and collecting light device;

at least one collecting lens barrel disposed on the top of the lampshade, a free ends of the at least one optical fiber connected to the at least one collecting lens barrel, the at least one collecting lens barrel disposed in the at least one through hole and projecting light into the lampshade, the light from the at least one collecting lens barrel extending through a hollowed bottom of the lampshade;

at least one LED light source mounted onto an inner periphery of the lampshade, the at least one LED light source electrically connected to a power source and providing an auxiliary lighting effect when a natural light source is not enough.

2. The natural light guiding system used for plant cultivation as claimed in claim 1 , wherein the lampshade comprises multiple reinforcing members each having a slot longitudinally defined therein, the abutted connecting flanges received in a slot of a corresponding one of the multiple reinforcing members and secured by multiple bolts.

3. The natural light guiding system used for plant cultivation as claimed in claim 1 , wherein the lampshade comprises a partition disposed on the top plate and the partition is separated from the top plate such that a receiving space is defined between the top plate and the partition; the at least one LED light source electrically connected to at least one transformer, wherein the at least one transformer is received in the receiving space and electrically connected to a power source.

4. The natural light guiding system used for plant cultivation as claimed in claim 2 , wherein the lampshade comprises a partition disposed on the top plate and the partition is separated from the top plate such that a receiving space is defined between the top plate and the partition; the at least one LED light source electrically connected to at least one transformer, wherein the at least one transformer is received in the receiving space and electrically connected to a power source.

5. The natural light guiding system used for plant cultivation as claimed in claim 3 , wherein the at least one LED light source has a back separated from the inner periphery of the lampshade and the at least one LED light source has a series of fins formed on the back thereof for providing a heat dissipation effect to each of the LED light source.

6. The natural light guiding system used for plant cultivation as claimed in claim 4 , wherein the at least one LED light source has a back separated from the inner periphery of the lampshade and the at least one LED light source has a series of fins formed on the back thereof for providing a heat dissipation effect to each of the LED light source.

7. The natural light guiding system used for plant cultivation as claimed in claim 5 , wherein there are multiple lighting devices and the lampshade of each of the multiple lighting devices has multiple collecting lens barrels disposed thereon, and wherein the chasing light and collecting light device includes a first plate, a second plate and a third plate sequentially separated from one another, multiple condensers and an automatic tracking sensor mounted onto first plate, the second plate including multiple through holes defined therein, wherein each through hole in the second plate aligns with a corresponding one of the multiple condensers, the third plate including multiple concentrators mounted thereon, wherein each concentrator aligns with a corresponding one of the through holes in the second plate and each concentrator has multiple optical fibers connected thereon, each concentrator connected to a corresponding one of the multiple collecting lens barrels.

8. The natural light guiding system used for plant cultivation as claimed in claim 6 , wherein there are multiple lighting devices and the lampshade of each of the multiple lighting devices has multiple collecting lens barrels disposed thereon, and wherein the chasing light and collecting light device includes a first plate, a second plate and a third plate sequentially separated from one another, multiple condensers and an automatic tracking sensor mounted onto first plate, the second plate including multiple through holes defined therein, wherein each through hole in the second plate aligns with a corresponding one of the multiple condensers, the third plate including multiple concentrators mounted thereon, wherein each concentrator aligns with a corresponding one of the through holes in the second plate and each concentrator has multiple optical fibers connected thereon, each concentrator connected to a corresponding one of the multiple collecting lens barrels.
