Natural light guiding system used for plant cultivation

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.
