Abstract

In a plant cultivation apparatus having artificial lighting, since extraneous light has not been actively used, artificial lighting and extraneous light are used in combination. SOLUTION: LED is used for artificial lighting, and multiple detectors that detect the intensity of extraneous light are mounted in the LED lighting panel. When the output of the photodetector at that time is larger than a predetermined value, the LED in the area covered by the photodetector is controlled to be turned off. When the LED lighting is turned off, a means to control the lighting of the LED covered by the photodetector when the photodetector output becomes smaller than a predetermined value has been introduced.

Description

  The present invention relates to a plant cultivation apparatus that forms a multi-stage plant cultivation space at the top and bottom and controls the intermittent lighting of LEDs according to the size of external light in each cultivation space.

Multi-stage plant cultivation equipment with various lighting facilities is used in practical tests. However, since these plant cultivation apparatuses are premised on artificial lighting already installed in the apparatus, there is no need for a function for effectively utilizing external light such as sunlight.
Moreover, it is expected that the plant growth can be stabilized and the quality of the cultivated plant can be made uniform by blocking the surroundings of the apparatus from the external light and carrying out the plant cultivation using only the artificial lighting laid.

  However, in order to grow plants using only artificial lighting without using extraneous light such as sunlight, the artificial lighting is always turned on. was there.

  The problem to be solved is to save power consumption of the artificial lighting installed.

  The present invention compares the signal from the light intensity detector mounted in the LED lighting panel with a value corresponding to a predetermined light intensity in the control unit when the LED lighting is turned off for a certain time at a certain time interval, If the value of the signal from the detector is large, the LED in the region corresponding to the detector is turned off, and if it is small, the power is saved by turning on the LED.

  In the plant cultivation apparatus of the present invention, the output signals of a plurality of light intensity detectors mounted on the LED lighting board change depending on the direction of the external light. Therefore, by turning on or off the red LED and the blue LED mounted in the area near the detector according to the external light intensity, finer management of light irradiation to the plant becomes possible.

It is explanatory drawing which showed the whole plant cultivation apparatus. It is explanatory drawing which showed the apparatus for plant cultivation. It is explanatory drawing which showed the LED illumination board. It is explanatory drawing which showed the method to a culture medium and liquid supply.

  The intensity of external light can be detected by mounting multiple light intensity detectors on the LED lighting board and turning off the LED lighting at regular time intervals and for a certain time. By this method, the LED lighting board is divided into multiple areas corresponding to the detectors, and the LEDs mounted in each area are turned on or off collectively for each area, making it possible to carry out more detailed lighting management for plants. .

  FIG. 1 is a conceptual diagram showing the whole of the present invention. By using a transparent material as a partition wall with the outside, sunlight is irradiated to a multi-stage plant cultivation area, and this light can be used effectively.

  FIG. 2 shows devices related to multi-stage plant cultivation installed inside and outside. That is, it is a control part which sends out a control signal by the signal processing of the shelf which provides a multistage plant cultivation space, the water tank for culture solutions divided | segmented for each shelf, and various detectors, and its result.

  FIG. 3 shows an LED illumination substrate. By mounting red and blue LEDs substantially evenly, arranging a plurality of photodetectors and dividing the LEDs into the number of detectors, lighting / extinguishing control can be managed finely.

  FIG. 4 shows the medium on the upper shelf and the method of supplying liquid. The remaining amount of the liquid supply on the shelf is collected, returned to the water tank, and the culture solution is circulated by the pump in the water tank. Further, by detecting the liquid temperature and pH in the aquarium, it becomes possible for the grower to appropriately take an optimum action.

  By effectively using external energy, it is possible to reduce plant cultivation costs.
