The present invention relates to a lighting device and a management system for plant cultivation, and more particularly, to an LED lighting system capable of promoting and managing plant growth by automatically adjusting the wavelength of light according to the growth cycle of a plant.

Plants grow through photosynthetic activity that uses light energy to synthesize glucose from carbon dioxide and water. Photosynthesis is divided into a light reaction that requires light and a dark reaction that does not require light. Here, the light reaction converts light energy into ATP molecules and NADPH2 molecules in the grana of the chloroplast to supply energy, inorganic phosphoric acid, reducing power and hydrogen to the Calvin cycle of the dark reaction. And, the dark reaction obtains bioenergy necessary for growth by synthesizing glucose using ATP and NADPH2 molecules in the stroma of the chloroplast.

At least one LED light 251 is assembled or built in any one surface of the upper frame 250 (eg, the surface in the direction of the seating frame 210 ) to supply light in the direction of the cultivated plant.

The first height adjustment bar 221 is fixed and configured in a state in which one side in the lower direction is attached to one side of the seating frame 210 , and the other side in the upper direction is opened to face the upper frame 250 direction. .

The second height adjustment bar 222 has an upper side attached to one side of the upper frame 250 , and the other side of the lower direction is raised and lowered in a state of being assembled to the other side of the first height adjustment bar 221 . configured to be In this way, the height of the upper frame 250 coupled to one side of the second height adjustment bar 222 may be adjusted by the lifting operation of the second height adjustment bar 222 .

As such, the lifting structure of the second height adjustment bar 222 is not limited to any one of the above forms, and can be applied by changing it to various forms and structures.

In addition, as shown in FIG. 3 , the LED lighting device 200 includes an interface module 206 , a height sensing unit 230 , a lighting height detection module 224 , an MCU 205 , a converter 202 , and a channel. It further includes a control module 203 , a height adjustment module 108 , and the like.

The interface module 206 may include a remote wireless communication unit, a keypad, a display panel, a memory, a microprocessor, and the like, and may be configured to be linked with a main board embedded in the upper frame 250 or the seating frame 210 . The interface module 206 performs wireless communication with the wireless repeater 300 and the mobile communication terminal 400 .

Alternatively, the current growth cycle of the cultivated plant is determined by reflecting the height value. That is, the growth cycle is determined whether the cultivated plant is in one of the germination phase, growth phase, flowering phase, and fruiting phase.

[Table 1]

Next, the MCU 205 reads the optical compensation point (PPFD) corresponding to the determined growth cycle from the database set as shown in Table 1 above, and generates an output amount control signal according to the light emission control information according to the read optical compensation point. Thus, it is transmitted to the channel control module 203 .

And, g is the red wavelength occupancy ratio optimally set according to the growth cycle of the cultivated plant. In other words, x may be a ratio occupied by a red wavelength in the LED lighting of a combination of a red wavelength and a blue wavelength. If, among 10 LEDs, there are 3 red wavelength LEDs and 7 blue wavelength LEDs, x is 30% and the substitution value may be 0.3.

When the illuminance value required for the cultivated plant is calculated through Equation 1 as described above, the MCU 205 calculates the output amount of the corresponding LED light 251 using the control function shown in Equation 2 below. do.

[Equation 2]

E = I/d ² ,

I = hW,

W = Ed ² /h

Here, W is the output amount of the LED light 251. In addition, the aforementioned E is an illuminance value required for the cultivated plant, and I is a luminance value set according to the output amount (W) of the LED light 251 . And, d is the distance (or the height of the LED light 251) between the potted plant and the LED light 251 in which the cultivated plant is planted. In addition, h is a proportionality constant.

In this way, the MCU 205 calculates the output amount (W) of the LED light 251 by substituting the required illuminance value (E), the luminance value (I), the height value (d), etc. in Equation 2, and then the LED light The on/off duty ratio of the LED lighting 251 is set to correspond to the output amount W of 251 and an output amount control signal including duty ratio information is generated.

In addition, MCU 205 generates a height control signal of the LED light 251 for changing the height of the current LED light 251 by reflecting the growth cycle and height value of the plant, and raises the generated height control signal to a height. sent to the control module 108 .

The height adjustment module 108 changes the height of the LED light 251 of the upper frame 250 as well as the second height adjustment bar 222 by rotating at least one motor according to the height control signal.

Meanwhile, the converter 202 converts the commercial power source 201 from the outside into a DC driving power source 202 having a preset voltage level and supplies it to the channel control module 203 . The converter 202 may be configured as an AC/DC converter or the like.

The channel control module 203 receives an output amount control signal including duty ratio information from the MCU 205 . Accordingly, the channel control module 203 generates an on/off dimming control signal for each of two or more LEDs such as red, green, blue, and white configured in the LED light 251 according to the duty ratio of the output amount control signal, and on/off Controls the on/off dimming operation of two or more multi-channel LEDs such as red, green, blue, and white according to the dimming control signal.

When the height detection control signal is received from the MCU 205 , the height sensing unit 230 transmits an infrared signal to the first and second infrared transmitters H1 and L1 . At the same time, the first and second infrared receivers H2 and L2 receive infrared signals. At this time, since the height sensing unit 230 is lifted by the lifting operation of the second height adjustment bar 222 , when the infrared signal reflected only by the second infrared receiver L2 is received, the height detection signal is transmitted to the MCU 205 . do. Accordingly, in the MCU 205 , the MCU 205 is the height of the binding point between the first height adjustment bar 221 and the second height adjustment bar 222 based on the height of one lower end of the first height adjustment bar 221 . , and the height of the height sensing unit 230 configured in the second height adjustment bar 222 may be calculated to calculate the size or height value of the cultivated plant.
