Description

  The present invention relates to a luminaire using a semiconductor light emitting device to compensate for the lack of sunshine in outdoor cultivation and house cultivation. Semiconductor light emitting elements include electroluminescence (EL) and laser diode (DL). In the present application, a semiconductor light emitting element will be described as an LED (Light Emitting Diode) (light emitting diode).

  In recent years, research and development has been thriving to promote growth by applying artificial light to cultivated plants in buildings. For example, US Pat. No. 6,921,182 enhances plant growth by arranging an orange first LED group, a red second LED group, and a blue third LED group at an appropriate ratio and illumination angle. This is an inexpensive and highly efficient LED lamp. US abstract 2001-47618 also uses red and blue LEDs alternately distributed on the base as a light source to provide continuous light similar to the sun and to control the work associated with light emission. Is. For semiconductor light emitting devices such as LEDs, depending on the type of plant, selectively using light of a specific wavelength that is convenient for the growth of each plant, or controlling the light intensity, illumination time, etc. The feature is that it can be easily performed. Such an LED lamp is provided in the form of a panel in which LEDs are assembled or in the form of a light bulb, and is firmly fixed to the ceiling or wall surface of a so-called plant factory. Recently, even in large-scale house cultivation with various facilities, an example of using an LED lamp fixed to a support column has come out.

  Although it is a plant factory with the momentum that seems to change the history of crop cultivation at once, the cultivation of open land and house cultivation (those with small scales of equipment and tunnel struts) that have been cultivated so far will be lost It does not mean that However, there is a big problem of lack of sunshine in outdoor cultivation and house cultivation. If there is a lack of sunshine due to long rain or cloudy weather, the cultivated plants will be adversely affected. If stable sunshine is not obtained, for example, peach farmers do not wear peach fruits, and even if they are worn, they suffer damage such as poor coloring and sugar content. In addition, tomato cultivation causes problems such as leaf dying and tearing. Some may have symptoms of the chief. The lack of sunlight is a big problem. Currently, there is an urgent need to solve such problems and advance outdoor cultivation and house cultivation.

  According to Japanese Patent Application No. 2009-192895, the present inventor needs an easy-to-install illuminating device to compensate for the lack of sunshine in outdoor cultivation and house cultivation. It was pointed out that LED lamps in conventional plant factories were not easily used when needed for outdoor cultivation and house cultivation, and lacked flexibility in application. Then, a new lighting device for plant cultivation was proposed. In addition, Japanese Patent Application No. 2010-158288 proposed the optimal power supply for such a lighting fixture.

  Japanese Patent Application No. 2009-192895 discloses an agricultural net for covering a plant together with electric wires for supplying power to a plurality of semiconductor light emitting elements to supply power to the semiconductor light emitting elements in order to compensate for the lack of sunlight in outdoor cultivation and house cultivation. It is attached as a lighting fixture for plant cultivation. The equipment used in the open ground and house should not be a hindrance to farming, should not be bothersome to handle, and can be easily installed or removed even by grandpa grandma who is the bearer of the current open ground and house. .

  The fact that this invention is really important is supported by a later issue of the Nihon Keizai Shimbun published on January 25, 2010, titled “Farm agriculture into the“ solar industry ”.” Agriculture and forestry are positioned as leading industries.

  In this way, with the eye on the plant factory now, the proposal of a lighting device that can grow plants that focus on open field cultivation and relatively small-scale house cultivation is an extremely important advance in this field. there were. Therefore, in order to further expand the options, the present inventor has a different type from the above-mentioned invention, and can be easily installed and used even by grandpa grandma who is the bearer of the current open space and house, or without thinking about the power supply I thought I wanted to help make up for the lack of sunshine by providing lighting equipment to grow such plants. An object of the present invention is to solve such problems.

  The above-mentioned problem is that a power supply unit including a solar cell, a secondary battery for storing the output of the solar cell, and a point-off unit that controls turning on / off of a semiconductor light emitting element described later, and the power supply unit An illuminating unit having the semiconductor light emitting element for illuminating the plant by emitting light using the output of the secondary battery, and for supporting the illuminating unit and standing in the soil beside the plant This is achieved by providing a lighting device to compensate for the lack of sunshine in outdoor cultivation and house cultivation. The solar cell of the power supply unit is arranged at the top of the lighting device as a preferred embodiment. The illumination unit is formed by using, for example, an LED as a semiconductor light-emitting element for plant growth, and being attached in such a direction that light emitted from the LED hits a plant to be illuminated. You can start using this luminaire by placing the props in the cultivated soil near the plants and screwing them up. The electric power generated by the solar battery is stored in the secondary battery, and this electric power is supplied to the LED by turning on the extinguishing means. By applying the light emitted from the plant-growing LED to the plant to be illuminated, it is possible to help solve the shortage of sunshine, thereby reducing the stress (fatigue) of the plant. Since LEDs generally do not generate much heat, they can be illuminated close to plants. This lighting device is simply the same as the past work of inserting Ibo bamboo (registered trademark) into the soil of a cocoon or planter, because it only stands by inserting a pillar or screwing it into the soil near the stem or trunk of the cultivated plant In this way, it can be easily installed by anyone. In addition, a plurality of lighting fixtures for plant growth can be distributed and installed at any place in the field. Since the power supply unit is equipped with a solar cell, the electricity bill is free and wiring for the power supply is basically unnecessary.

  In addition, as said support | pillar part, the support | pillars, such as a resin-coated steel pipe, the tunnel support | pillar used as a resin-coated iron wire, etc. can be utilized for this invention as it puts in the soil and stands. If the tip of the column is sharpened, it will be easier to pierce the ground. As the extinguishing means of the power supply unit, a general contact type switch, an optical sensor switch equipped with an optical sensor to turn on the switch when the environment becomes dark, a timer switch to turn on at a set time, etc. are used. I can do it. The optical sensor can be designed using a solar cell. More complicatedly, the optical sensor switch and timer switch are combined to turn on, for example, from sunset to 3 hours after yesterday's sunset time, or from 3 hours before yesterday's sun rise time to sun rise. It is possible to design such as For the daylight rising time and sunset time, the time when the optical sensor switch was operated yesterday is recorded in the storage unit of the timer.

  Optimized according to the type of plant and the purpose of breeding, such as using red LED alone or mixing red LED and blue LED, for example, 4 to 1 Just do it. LEDs with various wavelengths have been developed. Based on the photophysiology of plants, red has a wavelength in the range of 660 nm ± 50 nm, and blue has a wavelength in the range of 470 nm ± 50 nm. is there. Furthermore, it can comprise so that the light emission time and light emission pattern of LED can be controlled. In addition to lighting continuously, there may be flicker. For example, in addition to the technique described above, the existing technique can be used as a reference, so that further explanation is omitted to avoid complication. Such an LED illumination unit is provided around the power supply unit and the support unit that supports them. It should be noted that when mounting the LED in such a direction that the light of the LED hits the plant to be illuminated, the LED may be directed directly to the plant to be illuminated, but without this, if a prism or mirror is provided, It is possible to direct light toward the plant. Or you may make it provide the mechanism which can control the direction of a prism, a mirror, or LED.

  Next, the support column can be provided so that the height can be adjusted according to the growth of the plant. For example, if it is desired to illuminate the plant from above, the illuminator should be adjusted to increase its height in accordance with the growth of the plant. For this purpose, the strut part can be configured to be extensible and fixed at an appropriate length like an antenna, for example, or the strut part is divided into parts like a fishing rod, and the parts are added and connected What is necessary is just to comprise so that it can expand | extend. Alternatively, the height can be adjusted even if the column portion is configured like a scale. Alternatively, for example, if it is desired to prevent the shadow of the leaf from being applied to the solar cell during plant growth, the same configuration as described above may be used. In addition, in order to adjust so that it may be in a position higher than the height of the plant in which a solar cell grows, you may comprise so that adjustment which makes a solar cell part high upwards with respect to an illumination part can be performed. Or you may comprise so that a solar cell part may be isolate | separated and a wire may be stretched upwards and it may be hung on this.

  Next, the illumination unit may be provided along the support column. This is a configuration when it is desired to illuminate the plant from the side. For this, a plurality of LEDs are used. Several LED can be comprised by connecting each LED lamp with electric wires, such as a vinyl covering wire. An electric wire called a flat cord in which conductive wires covered with a resin film are bundled in a band shape can be used. Alternatively, an LED string including a wiring can be configured by surface mounting (Surface Mount). Other methods may be adopted. A plurality of LEDs may be connected in series, a plurality of groups connected in series may be connected in parallel, or the like. For example, such an LED is embedded in the surface of the support column in the longitudinal direction, or is stored in a support column composed of a transparent pipe. Alternatively, it can be realized by suspending the tape-like LED or the tube-like LED from the upper part of the illumination device.

  Next, the said illumination part shall be provided in the horizontal direction so that the arrangement | sequence of a plant may follow. For example, if an illuminating part is provided on the top of the supporting part so that it has a T-shape between the supporting part and the illuminating part, several plants lined up along the fence on both sides of the supporting part that are placed in the soil. You can take on the illumination.

  Next, the erasing means can be a remote control switch. As described above, it is possible to design the power supply unit to be a general contact type switch. However, in a situation where a plurality of lighting fixtures are distributed and installed in a wide field, it is not easy to turn each unit ON / OFF. Therefore, the illuminating device for plant growth of the present invention is provided with a communication unit, and a command from the remote controller is received so that the extinguishing means turns on / off the illuminating unit. Accordingly, it is possible to simultaneously turn on / off a plurality of illumination devices. A wireless or far-infrared type can be arbitrarily employed for the communication unit. The illuminating device of the present invention can stand alone by the column part, and the illuminating part for plant growth can be configured so as not to be supplied with power from the outside with a power supply part, which hinders agricultural work. Since it is difficult, it may be desirable to avoid connecting adjacent lighting devices with a line just for the extinction means.

  Next, the extinguishing means can control the semiconductor light emitting element to emit light in pulses. Pulse emission, which is different from continuous illumination, is used in plant factories for the purpose of further promoting photosynthesis by efficiently combining light and dark reactions. Since the LED can blink at high speed, it is easy to apply pulsed light emission to the present invention. For example, with a multivibrator or a positive feedback operational amplifier, for example, pulse light emission with a period of 400 μs is performed without dropping the light amount. This is convenient from the viewpoint of energy saving.

  Next, the semiconductor light emitting element may be a red LED alone, but may be a combination of a plurality of types of LEDs having different emission colors. The photosynthesis that plants perform is that chlorophyll receives light energy and produces sugar from water and carbon dioxide. This chlorophyll reflects green light in the sunlight spectrum but easily absorbs red and blue light, and red light in the vicinity of a wavelength of 660 nm is particularly effective for photosynthesis. However, blue light having a wavelength of around 470 is effective when germination or leaves are formed. Therefore, for example, if two types of LEDs having different emission colors are combined, a combination of red and blue is common. For insect removal, depending on the type of insect, a green LED or a yellow LED may be combined. Moreover, the structure which is set as white LED which combined red, blue, and green LED is possible. It should be noted that a plurality of types of illuminating parts, which are combinations of LEDs according to special purposes such as the type of cultivated plant, each growth stage, and the desire to enlarge the leaves, can be configured to be exchangeable.

  Next, the semiconductor light-emitting element for plant growth may be composed of a plurality of types having different emission colors, and the extinguishing means may be provided for each type of the semiconductor light-emitting element. Although it varies depending on the plant to be cultivated, experience for the optimal luminescent color (wavelength) according to the purpose of promoting germination, promoting leaf growth, inducing flowering, suppressing flowering is now being accumulated. Therefore, the erasing means can be used conveniently by displaying the switch for each emission color or performing the display for each purpose. This can also be applied when the remote control switch has a plurality of types of switches. In addition, it is possible to design the program to have a microcomputer so that the control of changing the emission color can be performed in a programmable manner based on the experience of the farmer who will perform the outdoor cultivation and house cultivation according to the present invention.

  Next, the direction of the solar cell of the power supply unit may be variable. The solar cell may be provided horizontally or provided with an inclination of, for example, 30 degrees with respect to the inclination angle, but it is more convenient if the inclination angle of the solar cell is provided so that the user of the lighting device can adjust it. . Similarly, the azimuth angle can be adjusted by the user. In this case, it is convenient to have a compass.

  Next, the top can be formed in a substantially spherical shape so as not to catch the net. A net may be hung or removed on vegetables, but it is not preferable that the net gets caught in such a case. As a countermeasure, for example, if the mesh is a 4 cm square net, it is designed to have a substantially spherical top with a diameter of 10 cm. If a solar cell is arranged on the top, a transparent, substantially spherical cover of a required size that allows sunlight to pass therethrough may be attached.

  The present invention also includes a power source unit including a solar cell, a secondary battery for storing the output of the solar cell, and a point-off unit that controls turning on / off of a semiconductor light emitting element to be described later. An illuminating unit having the semiconductor light emitting element for illuminating and growing the plant by emitting light using the output of the secondary battery, and supporting the illuminating unit and standing in the soil beside the plant An illuminating device comprising a supporting column part, and a cultivation land that is intended to grow the plant and to stand the illuminating device near a plant stem or trunk using the supporting column part, It can be provided as an illumination system to compensate for the lack of sunshine in outdoor cultivation and house cultivation. Various ideas as described above can also be applied to this illumination system.

  With this invention, a new type of illuminating device suitable for plant growth, which can be easily installed and used by grandpa grandma who is the bearer of the current outdoor field and house, or does not need to think about power supply Was provided.
