Description

Plant cultivation lighting device with LED

The present invention relates to a plant cultivation lighting apparatus using LEDs and a method for plant cultivation using the same, and more specifically, to promote the germination, flowering, and growth of plants by appropriately mixing the ratio for each specific wavelength band of light emitted from the LED It relates to a plant cultivation apparatus and method.

Incidentally, incandescent lamps, fluorescent lamps, halogen bulbs and high-pressure sodium bulbs have been used for lighting for plant growth, but recently, it is a semiconductor light emitting diode for plant cultivation that replaces them. It can produce the effects of chloroplasts and can have a disastrous economic impact from energy savings and environmental protection. The plant growth and growth apparatus of a lighting device having such a light emitting diode for plant cultivation has been investigated for the growth and growth of plants by irradiating light with the optimum wavelength band and brightness according to the characteristics of the plant and the parameters to be controlled. A plant growth and growth apparatus using a light emitting diode that can be configured and controlled by a control unit has been disclosed (Patent Document 1), and similar documents provide various types of light emitting optimal wavelengths according to plant types and growth processes. Combining LEDs at an appropriate ratio, and one or two or more LEDs selected from LEDs such as red, blue, green, white, infrared, and ultraviolet rays are arranged on the board at an appropriate ratio and replaced according to the plant type or growth situation. There is a document (Patent Document 2) configured to be able to.

In addition, it is a closed LED plant factory, which is designed to produce pigments in small spaces for efficient production and short time cultivation. LED lamps with far-infrared light 730nm, red light 660nm, blue light 450nm with low power consumption Documents such as a plant cultivation device that improves plant growth promotion and consumes less power, such as a literature on high efficiency plant cultivation system (Patent Document 3) in a light enclosed space, are shown.

However, the plant growth apparatus according to the prior art, the following problems occur. As described above, in the related art, in order to produce a light source having a wavelength required for plant growth, germination, and flowering, a control unit must be installed through a network, and the control unit is integrated with the system and operated. This approach is theoretically possible but not practical, and leads to inefficiency. In order to construct the light source of the required wavelength with the control system, the size and the cost are increased, and the unused light source occupies unnecessary space when the required wavelength is being driven while the productivity balance is not met. In addition, the space in plant growth must maintain high humidity, and thus the replaceable parts cannot be free from aging or failure. In addition, the composition of the plant cultivation method in which the blue, red, and near-infrared light of 730 nm wavelength is mixed is effective in the growth part of certain plants, but causes problems in seed germination, and thus can be used in a limited way. According to a study, in 1952, HA Boswick and SB Hendricks measured the effect of light on the germination of lettuce seeds, and 670 nm red light had the greatest germination promoting effect, and 730 nm near-infrared light had a red light facilitation effect. It has been found to have an extinguishing effect. In addition, when the light of the two wavelengths cross each other for one minute, the germination rate was determined according to the wavelength of the last light irrespective of the number of times. Therefore, it can only be used in limited places locally.

Such a prior art has been developed for the use of plant factory control system, it can be seen that it is difficult to use in farms growing general plants. In addition, the structure of complex system form not only causes frequent breakdowns, but even if it is introduced, the structure is incapable of producing profits due to excessive investment costs and technical limitations. This is a problem of investment cost-effectiveness in foreign countries, and it is a fact that several institutions are trying to solve it.

Referring to Figures 1 to 14, the semiconductor light emitting diodes affecting plant production are selected and optimized. Since most light sources are developed for humans, sensitivity-based units are used, and photosynthesis does not respond to ordinary light sources. In order to construct the luminosity necessary for plant cultivation, it is necessary to use units corresponding to the characteristics of photosynthesis. All plants have growth requirements determined by growth photosynthesis and chlorophyll, and the leaves and fruits form. Plants grown under good conditions are thick in leaves, rich in vitamins and have a clear color or shape. The wavelength of light of the maximum effect of this plant photosynthesis is about 670 nm and about 430 nm, and the maximum effect of chlorophyll synthesis is about 655 nm and about 440 nm.
