Abstract

A plantation growth lighting system comprised of laser diode (LD) array and automatic control unit is disclosed herein. The lighting system of the present invention is used for multi-layer hydroponic or soil-based plantation growth facilities to substantially improve the intensity of light. Since the light can be controlled to only distribute over the plants, the energy efficiency and the light intensity control of the present invention will be much better than the conventional lighting system in plantation growth facilities. As a result, the plurality of vegetal species will grow well with higher density within/without a closed environment.

Claims

1. A plantation growth lighting system comprised of laser diode (LD) array and automatic control unit.

3. The method of claim 1 could be used within or without closed environment.

4. The method of claim 1 could be used for higher density of plantation due to full control of laser diode array that we are using.

5. The method of claim 1 have higher energy efficiency for lighting which lead to less heat emit to the system

6. The method of claim 5 could lead to that the transpiration of plantation is reduced and less water is evaporated into the air. AS a result, water consumption is lowered.

7. The method of claim 1 further comprising:

a auto detect system that can find any human or pet'"'"'s proximity to the system, it thereby can switch to other light source to prevent any possible harm.

8. The laser diode array of claim 1 can be implemented with high-power laser diode and light-splitting devices, such as refraction beam head for laser.

9. The laser diode array of claim 1 can be replaced with high-power laser generator (further including all kind of laser generators, such as chemical laser generator and solid-state laser generator) and optical fibers.

10. The method of claim 1 covers all embodiments that use laser as light source to provide lighting for plantations. These optical devices, e.g. mirror, may reflect, refract or split the original laser beam to generate multitude of laser beams or light with intensity in the acceptable range for plants.

2. The laser diode lighting system of the present invention is used for multi-layer hydroponic or soil-based plantation growth facilities to substantially improve the intensity of light.
