Description

Lighting device for rotary plant cultivation {LIGHTING DEVICE FOR ROTARY TYPE PLANT GROWING DEVICE}

The present invention relates to a lighting device for a rotary plant cultivator, and more particularly, to minimize light loss by installing lighting modules constituting a lighting cartridge mounted along the central axis of the rotary plant cultivator without a protective cover, By installing a transparent light-transmitting cover on the top of the lighting cartridge, when the rotary plant cultivator rotates 360°, residual nutrient solution will be prevented from falling into the lighting cartridge due to gravity and at the same time, the light transmission efficiency of the cultivated plants will be prevented from being lowered. It relates to a lighting device for a rotary plant grower capable of

Conventional plant cultivation was possible only in limited spaces such as vinyl houses, glass greenhouses, and open fields. For example, in the case of a plastic greenhouse among conventional plant cultivation, plants do not grow uniformly because a constant temperature is not maintained due to the temperature difference between the top and bottom of the inside, or the cultivation environment such as sunlight, moisture, and wind is not constant. Growth was also delayed.

In order to overcome these limitations, recently, plant factories and smart farms have been actively introduced.

Gravity sensor cell present in the crop by rotating the cultivation cartridge around the central light source with a structure that allows gravity movement using the rotating structure of a plant factory-type smart farm in an optimal growth environment such as temperature, humidity, and nutrient solution suitable for each crop's characteristics (Gravisensors) artificially stimulates the growth substances (Auxin hormone) generated to stand upright according to the movement of gravity and thereby promotes the growth rate of crops there is a bar

In the rotary plant cultivator, as the cylindrical rotating body rotates, the cultivation cartridge passes through the nutrient solution tank provided at the bottom. When it rotates around the light source in the center while holding the nutrient solution, the remaining nutrient solution reaches the top at 12 o'clock. While falling as water droplets due to gravity, they may flow into the lighting device. Therefore, conventional lighting devices are equipped with a transparent acrylic (or PC, glass) cover that surrounds the outside of the LED substrate in a circular shape in order to prevent failure of the LED substrate (or PCB board) due to leakage of nutrient solution.

However, since about 10 to 15% of the LED irradiation light is lost without passing through the cover due to the cover, there is a problem in that the lighting efficiency cannot be maximized.

Korean Patent Publication No. 10-2021-0065673 proposes a rotary hydroponic cultivation device including a lighting unit composed of a bar-shaped lighting module disposed on a rotating shaft of a driving frame. However, in the prior art, there is a problem in that the lighting module itself has a structure in which a protective cover is provided, and light loss that is irradiated to cultivated plants still occurs.

As described above, the bar-type LED lighting device, which is generally installed in a rotary plant cultivator, surrounds the outside of the LED substrate to prevent nutrient solution from flowing into the LED lighting device and causing failure of the LED substrate (or PCB board). is equipped with a transparent acrylic (or PC, glass, etc.) cover, and since about 10 to 15% of the light irradiated from the LED lighting device is lost without passing through the cover, the problem of not maximizing the lighting efficiency occurs. did

However, in the present invention, since the protective cover surrounding the outside of the substrate 101 is not provided, there is an effect of minimizing the dimming loss of the LED chip 102 .

The lighting cartridge 10 includes a PAR lighting module 111 having a light source emitting photosynthetically active radiation, a UV lighting module 112 having a light source emitting ultraviolet (UV), infrared, At least one IR illumination module 113 having a light source emitting IR) may be provided.

Photosynthetically effective light (or photosynthetically effective radiation) irradiated from the PAR lighting module 111 means visible light effective for photosynthesis showing a wavelength range similar to the visible light range of 380 to 760 nm with a wavelength between 400 and 700 nm.

More specifically, these wavelength bands can generally be divided into three wavelengths: blue light (400-500 nm), green light (500-600 nm) and red light (600-700 nm), and the blue light wavelength (around 450 nm) specialized for leaf and stem growth. A red light wavelength (approximately 650 nm) specialized for florescence differentiation, leaf and stem maturation, and root growth is irradiated. The LED chips 102 may be mixed at a preset ratio and mounted on the substrate 101 .

The light irradiated in the above wavelength band is generated according to the state of light as well as photosynthesis, the phenomenon of controlling the differentiation process, the release of dormancy of seeds and spores, the timing and direction of cell division, the growth rate, and the form of light such as differentiation of cells and organs. It can induce a photomorphogenesis response.

A total of 12 lighting modules 11 are sequentially arranged with two PAR lighting modules 111, one UV lighting module 112, two PAR lighting modules 111 and one IR lighting module 113 Since the rotary plant cultivator R rotates 360° around the lighting cartridge 10, the light emitted from the lighting modules 11 can be equally irradiated to the cultivated crops at a constant rate with a time difference.

Therefore, there is an advantage that can overcome the limitations of economic feasibility and profitability due to excessive installation costs and light energy costs of lighting equipment used in existing plant factories or smart farms.

The ratio of the lighting modules 111, 112, and 113 is determined by the user's selection by pulse control (energy saving and growth promotion effect by turning on/off pulsed light), dimming control (light intensity control growth and functional enhancement by growth period), Light wavelength control (optimal light amount control by light wavelength selection for growth and functional component enhancement), light intensity control (irradiation intensity-micromolar control for each crop and growth period to improve growth and functionality and save energy) and irradiation time control (irradiation period and Improvement of growth and functionality and energy saving through time control) can be changed and applied in various ways by each or integrated control system in an optimal control method (development into artificial intelligence, AI agriculture) by plant cultivation data.

In the cartridge support 20, one or more cooling fans 21 may be installed at a portion coupled to the lighting cartridge 10, and the cooling fan 21 removes heat generated from the lighting cartridge 10. It can play a role in cooling and releasing it to the outside.

In addition, in order to prevent sufficient heat dissipation by the cooling fan 21 due to a narrow internal space of the lighting cartridge 10 formed in a substantially rectangular shape, a heat sink (not shown) is installed on the rear surface of each lighting module 11. It is also possible to improve heat dissipation efficiency by further bonding.

It can be designed as wider as the length.

Since the light transmission cover 31 is not mounted on all of the lighting cartridges 10, but only covers the lighting modules 11 disposed on the upper surface, the lighting modules in the other directions except for the lighting modules 11 in the upper direction. The light control efficiency of the s 11 can be 100%, and light control loss can be minimized as the upper lighting modules 11 and the light transmission cover 31 are formed of a transparent material.

One end of the pair of cover supports 32a and 32b may be coupled to and fixed to the lighting cartridge 10 and the other end may be coupled to and fixed to the light transmission cover 31 .
