Description

  The present invention relates to an illumination device using a semiconductor light emitting element for use in outdoor cultivation and house cultivation, and to a light shielding clip for causing the illumination device to acquire light shielding properties. Semiconductor light emitting elements include electroluminescence (EL) and laser diode (Laser Diode). 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 provided red and blue LEDs alternately distributed on a base as a light source, and provided continuous light similar to the sun and made it possible to control the work related to 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.

  Although it is a plant factory that seems to change the history of crop cultivation at once, this does not eliminate the cultivation of open-air cultivation and small-scale house cultivation that have been cultivated so far. 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 receive peach fruits, and even if they are worn, they suffer from damage such as poor coloring and sugar content. In addition, the cultivation of tomatoes causes problems such as leaf dying and ripening. Some may have symptoms of the chief. The lack of rays is a big problem. Currently, there is an urgent need to solve such problems and advance outdoor cultivation and house cultivation.

US Pat. No. 6,921,182 (FIG. 6) US abstract 2001-47618 (FIG. 1)

  In other words, there is a need for an illuminating device that is optimal for outdoor cultivation and house cultivation, and that can be easily installed to compensate for the lack of sunshine. Therefore, I thought to use the LED lamp of the above form for outdoor cultivation and house cultivation. However, the type that is firmly fixed to the ceiling or wall of the plant factory is not so flexible that it can be used immediately when needed for outdoor cultivation or house cultivation, and lacks flexibility.

  In general, light emission from a semiconductor light emitting element such as an LED has directivity. However, a general LED that emits light toward the front resin lens, such as a shell type, may generate scattered light from this resin lens. Depending on the object, strong light is seen even from an oblique rear side of the LED. I can do it. Therefore, we want to illuminate even after sunset or before dawn. At this time, even if the reflected light from the cultivated plants is unavoidable, the light directly seen from the LED resin lens can be seen obliquely from the rear. I want to make this as invisible as possible. It is also a problem that dazzling white light leaks from the open ground or house, but some people see the blue light and the spectacle where red light leaks even if not so dazzling as a kind of strange.

  Then, this invention makes it a subject to provide the lighting fixture suitable for open field cultivation and house cultivation, and to reduce as much as possible the light seen from diagonally behind this lighting fixture at the time of lighting.

  The above problem is that a plurality of semiconductor light emitting elements and electric wires for supplying electric power to the semiconductor light emitting elements are housed in a long casing having translucency in the illumination direction, and both casings are behind the casing. This is achieved by providing an illumination device with a shade in outdoor cultivation and house cultivation, characterized in that a shade for blocking light leaking from the edge to the back is provided. The long length may be several meters to several tens of meters or tens of centimeters. This is an arbitrary length because it depends on the conditions of the open ground and house. In addition, there is a case where a short one is connected to make a long one. The illuminating equipment housed in the long casing is less likely to get caught between the branches and leaves of the plants and between the house pipes, ropes and nets. Therefore, there is a feature that it is much easier to handle than connecting LED lamps connected with electric wires barely. There are casings that can be bent freely, those that can be bent a little, those that cannot be bent, etc., but they may be freely selected depending on the application. For example, an LED is used as the semiconductor light emitting element. Then, the light from the LED can help to solve the shortage of sunlight. Although not an essential requirement of the present invention, a commercial power supply is generally used for the power supplied to the LED. You may use the power source which farmers can obtain by themselves, such as wind power generation and small-scale hydroelectric power generation. If Smart Grid (trademark) becomes widespread, it will be possible to supply solar power generated in sunny areas to the lighting device of the present invention in rainy areas.

  Put this luminaire on an open-air cultivation plant, hold it on a rope that is passed between it, hang it on an agricultural net, hang it on a pillar of a house, etc. It can be used just by covering the top. It is possible to install it between plants. This illuminating device has the advantage that it is relatively easy to extend in an open field or house, or that the shape when placed on a plant is free. It is easy to install and remove during busy farming. In addition, when it is made to follow the above-mentioned agricultural net, when an agricultural implement is hooked on this long illuminating device, the agricultural net will be hooked together or it will be hooked first and will be pulled with the agricultural net. Therefore, the agricultural net acts to protect the lighting equipment. Although LED light is irradiated toward the plant from this illuminating device, the light applied to the shade among the light leaked obliquely rearward from the both edges on the short side of the casing is blocked by the shade. The degree of shading in the shade can be designed as needed from a maximum of 100 percent shading to a lower shading.

  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 or LED matrix including wiring can be formed by surface mounting (surface mount can be said to be long in two directions). Other methods may be adopted. In particular, it is desirable that waterproofness is imparted to those used in open spaces. A plurality of LEDs may be connected in series, a plurality of groups connected in series may be connected in parallel, or the like. Moreover, it can comprise so that LED and an electric wire can be extended using an extension connector etc. FIG. Since this is a general technique, a detailed explanation is omitted. The emission color of the LED is not limited to white, and it is arbitrary such as using a general research result and mixing a red LED having a wavelength of 660 nanometers and a blue LED having a wavelength of 460 nanometers in a ratio of about 4 to 1. . The light emission time and light emission pattern of the LED can be controlled. In addition to DC lighting, for example, pulse lighting of 400 microseconds may be used. Since the techniques already disclosed in the above-mentioned Patent Documents 1 and 2 and the existing techniques are used as a reference, further explanation is omitted to avoid complication. Or you can use what is currently under development or technology that will appear in the future. Such an LED is incorporated into a long casing. In addition, it is possible to illuminate a plant by providing a prism, a reflector such as glossy white or a mirror, a light diffusion cap, etc. without directing the light emitting part of the LED directly to the plant to be illuminated. is there. In addition, when using high output LED, it is good to take a heat dissipation measure.

  In order to attach this lighting fixture to a house pipe, rope, agricultural net, etc. as described above, an adhesive that supplies this lighting fixture to a place along the rope, etc. Adhesive tape for winding and fixing both, hook and loop fastener, wire, soft vinyl string with wire (vinyl tie), binding band such as Insulok (registered trademark) and bead band, clips such as eyeball clip, net hook, etc. Arbitrary attachments such as hooks and spiral tubes may be used. There is also a method of attaching a rope or an agricultural net between the shade and the adhesive tape. In addition, although it is a long illuminating device, if it is configured to be detachable for each unit, it is easy to extend the unit unit or replace it at the time of repair.

  The shade back can be used to attach the illuminator to a rope or agricultural net. However, in the case where the back portion of the shade is not used, since this lighting device is long, it is necessary to hang the adhesive tape, the wire, the binding band, and the net hook as described above around the lighting device. At this time, the shade may be tightened and deformed with these attachments. If you do not like this, it is recommended to provide a notch in the shade to avoid pressure on the shade by the fixture. If the fixture is positioned and tightened at a portion having the notch, the fixture is less likely to tighten and deform the shade. It is also possible to make the gaps in the notches invisible so that the shades in the notches overlap somewhat. Both are useful for improving the light shielding performance. In order not to block the light of the LED with the fixture, it is preferable that the notch is provided at a part removed from the LED.

  Alternatively, the shade may be broken by hand. A portion of the shade where the fixture is positioned and to be tightened can be cut to provide a notch for releasing the fixture. For this purpose, a shading material having a hand cutting property is used. For example, slip sheets with aluminum foil or polyethylene cloth can be used. It is convenient and convenient because it can be cut by hand without using tools such as firewood.

  The shade may be curved in the illumination direction. The curve has a fold with a corner and a curve that bends gently. In either case, the shade appears to effectively shield the light.

  The casing may be attached to the inside of a light shielding net or a light shielding film as a shade. That is, the shade net or the shade film itself is the shade. There are various types of light-shielding nets, such as those with a light-shielding rate of 40% to 100%, for example, and a desired one may be used. In addition to the light shielding net, a polyethylene light shielding film or the like can be used. A light shielding sheet disclosed in JP-A-2007-92245 is also helpful. In addition, you may make it provide the illuminating device provided with such a light-shielding net | network and a light-shielding film so that it can detachably attach to a cultivation plant as a light-shielding curtain. For example, a tunnel-like lead pipe is erected and attached so that the light-shielding curtain can be manually closed and opened along the lead pipe. Alternatively, it is convenient that the shading curtain is automatically opened and closed by providing motor-driven opening / closing means. Further, if an illuminance meter is provided so as to be able to control the opening / closing means, it is possible to perform control such that the light shielding curtain is closed at sunset or the light shielding curtain is opened at sunrise. Plant factory technology can be used for illumination after sunset.

  In addition, the above problem is that a plurality of semiconductor light emitting elements and an electric wire for supplying power to the semiconductor light emitting elements have a long casing having translucency in the illumination direction and light shielding in the anti-illumination direction. Provided with a holding part for supporting the stored lighting equipment in outdoor cultivation and house cultivation by concavely bending the light-transmitting side on the side having translucency, and also provided with an attaching part for attaching to a column or rope It is also achieved by using a light shielding clip. Since the surface side having light shielding properties is convexly curved in the backlit direction of the casing, it is possible to receive a line of sight from the oblique rear side on the surface side having light shielding properties. For this purpose, the casing is held while being pressed by the clamping portion of the light shielding clip. The casing sandwiched between the light-shielding clips in this way is attached to a column or rope by the light-shielding clip attachment part. In addition, as an illumination device used for the light-shielding clip, an illumination device that can be bent when pressed by the holding portion is used. Note that bending is also included in the curvature.

  Open-air cultivation and house cultivation follow the sun's appearance and weather, but according to the lighting device of the present invention, in the case of insufficient sunlight, the semiconductor light-emitting element can be turned on during the day, or after sunset or before dawn. And you can make up for the shortage. This can reduce plant stress (fatigue). On the other hand, as described in Japanese Patent Laid-Open No. 5-21822, the sunlight is used as it is to control the growing environment, and as disclosed in Japanese Patent Laid-Open No. 7-79646, the air pressure is set inside so as not to be adversely affected by the weather and the climate. There is an invention of a farm that covers a cultivation area with a roof that is laid out. Even if it is not such a large scale, it is sufficiently possible to make it possible to perform illumination management like a plant factory using artificial light in ordinary grounds and houses targeted by the present invention.

  In order to easily attach the lighting device of the present invention to a rope or an agricultural net, for example, a net hook may be attached to the lighting device in advance. If the net hook is attached to the rear side of the shade, the above-described problem of deformation of the shade does not occur even if there is no notch.

  An illuminating device provided with a shade for blocking light leaking from both edges on the short side of the casing is accommodated in a long casing having translucency in the direction of illumination. This is the first idea proposed. In addition, the present invention is the first to propose a light-shielding clip that holds an illuminating device in a concave curve in the illuminating direction and forcibly blocks the line of sight from behind. This makes it easy to install and remove anytime if necessary in outdoor cultivation or house cultivation, and can reduce the light seen from diagonally behind. Has a remarkable effect. The industrial benefits of the present invention are immeasurable.

  The present invention widely uses semiconductor light-emitting elements. In the embodiment described below, an example using LEDs among them will be taken up.

  The LED 20 is positioned on the flexible substrate 2 to form an LED string including wiring by surface mounting. The front and back surfaces are made of silicone resin, and the front surface side translucent layer 10 and the back surface side white layer 11 Then, the tape-shaped LED lamp 1 is formed. A connector 26 is provided at the end of the substrate 2 in the longitudinal direction so that a plurality of the LED lamps 1 can be connected. A black silicone resin sheet having a width wider than the width of the tape-shaped LED lamp 1 in the short direction is provided on the back surface of the white layer 11 of the tape-shaped LED lamp 1, and shades 12 are provided on both sides of the tape-shaped LED lamp 1. Form. In order to make this part easy to understand, it is shown by a mesh line in FIGS. Moreover, the notch part 13 for letting a binding band pass was provided in the location which opposes the both edge part vicinity of the tape-shaped LED lamp 1 of this shade 12. FIG. This pair of notches 13 is provided at a plurality of locations in the longitudinal direction of the shade 12. As shown in FIG. 3, the LED string is a unit in which three LEDs 20 and one resistor 21 are connected in series and connected to a plus-side wiring 22 and a minus-side wiring 23. It is. A plurality of units of LED strings are connected in parallel to form a tape-shaped LED lamp 1. The plus side wiring 22 is connected to the connection terminal 25 of the connector 26 of the tape-shaped LED lamp 1 shown in FIG. 1, and the minus side wiring 23 is connected to the connection terminal 24 of the connector 26. This drive power supply is 12 volts DC. Light emitted from each LED 20 is illuminated from the translucent layer 10. However, the light that is going to go diagonally backward from both edges of the tape-shaped LED lamp 1 is blocked by the shade 12. Instead of providing the shade 10 on the back surface of the white layer 11, the shade may be separately connected to both edge portions of the white layer 11 instead. Alternatively, the back surface of the substrate 2 may be directly covered with the shade 12 instead of providing the white layer 11 on the back surface of the substrate 2.

  FIG. 4 is an explanatory diagram of a state in which the illumination device of this embodiment is used. Here, the bird net N is directly covered directly over the fruit tree T. At this time, the tape-shaped LED lamp 1 with the shade 12 is placed so that the side of the translucent layer 10 faces the fruit tree T. In other words, the binding band (not shown) is passed through the notch 13 so that the shade 12 faces outward, and is attached to the bird net N with the binding band. The binding band may not be passed through the notch 13 but may be attached to the bird net N by hanging on the outer edge of the shade 12. In this case, the binding band deforms the shade 12 to provide some light shielding performance. May decrease. In FIG. 4, bird nets N and fruit trees T are not requirements of the present invention.

  A plurality of so-called bullet-type LED lamps 4 are connected to vinyl-coated electric wires 42 and 43 with their lead wires 40 and 41 in the same polarity, and are accommodated in a transparent PVC tube 30 to form a tube-shaped LED lamp. 3. All the LED lamps 4 are aligned in such a posture that the emitted light is directed in substantially the same direction (FIG. 5 shows only one LED lamp 4, but the other lamps are also substantially aligned in this direction. ). In order to prevent the LED lamp 4 and the electric wires 42 and 43 from moving in the tube 30, a configuration example using a heat shrinkable tube will be given. As the heat shrinkable tube, a polyolefin tube may have a relatively high transparency. A black shade 31 made of PVC that is curved in the direction of the tube-shaped LED lamp 3 is attached to the back surface of the tube-shaped LED lamp 3 (portion corresponding to the back side in FIG. 5). The shade 31 has a width that is greater than the width in the short direction of the tube-shaped LED lamp 3, and is curved so that both edges cover the line of the tip of the lens of the LED lamp 4. A slit-like notch 32 was provided from both edge portions of the shade 31 to the vicinity of the attachment location of the shade 31, and a circular hole 33 was formed at the end thereof.

  In FIG. 5, this use state is also shown. Since the lighting device of this embodiment is attached to the reinforcing rope R provided on the agricultural net, and the lighting device and the rope R are bound by the wire W. However, at this time, the wire W is passed through the notches 32 on both sides of the shade 31 so as not to be deformed by crushing the shade 31 with the wire W or the like. FIG. 5 shows a state where the wire W reaches the circular hole 33. In FIG. 5, the rope R and the wire W are not requirements of the present invention. In this way, the shade 31 can keep the curve in the direction of the tube-shaped LED lamp 3 and can well block the light going out obliquely backward.

  An LED string including wiring is formed by surface mounting on the flexible substrate 27 and the LED string including the wiring is formed. The LED string is fitted into a concave portion of the lower case 50 made of resin on the back surface side, and the transparent resin on the front side is placed thereon. An upper case 51 made of the product is covered and bonded from the side where the concave portion is formed to form the LED lamp 5 with the case. A black shade 52 made of polyethylene cloth having hand cutting properties is attached to the back surface of the lower case 50 of the LED lamp 5 with case. The shade 52 has a width that is greater than the width in the short direction of the cased LED lamp 5.

  In FIG. 6, both sides of the black shade 52 are shown as being manually shredded to the vicinity of the cased LED lamp 5. The cut section 54 of the cut section 53 is drawn with hatching. Wires and vinyl ties are passed through the slits 53 on both sides. This prevents the shade 52 from being crushed and deformed. Further, since it is not necessary to provide the notch 32 and the circular hole 33 as in the second embodiment, the manufacture is easy, and it is also a great advantage for the user that the slit 53 is easily provided at a desired position.

  Here, the tape-shaped LED lamp 1 of the first embodiment in which the shade 12 is not formed is used. A thread 60 for passing the tape-shaped LED lamp 1 through the agricultural light-shielding net 6 is provided at an appropriate interval, and the tape-shaped LED lamp 1 is stopped here. The shading net 6 and the threading ring 60 used here are made of polyethylene, and the threading ring 60 is provided on the warp (warp) of the shading net 6 as shown in FIG.

  It can be said that the light shielding net 6 is an extremely large shade for preventing the light of the LED 20 from leaking obliquely behind the tape-shaped LED lamp 1. In addition, in the case of performing illumination management such as an artificial light utilization type plant factory even during the daytime, the light shielding net 6 also serves as a sunlight shielding means. A light-use house can be realized, and it is possible to plan and cultivate plants even in open spaces and small houses.

  As shown in FIG. 8, the agricultural net 7 is formed by cutting out the portion that becomes the mesh 70 from the colored soft PVC sheet. Between the mesh 70 and the mesh 70, the substrate 2 portion on which the LED 20, the resistor 21, and the wirings 22 and 23 used in the first embodiment are fixed with an adhesive, and a transparent coating 71 is placed on the substrate 2 in the longitudinal direction. The illuminating device of the present embodiment is obtained by adhering the adhesive portions 72 of the two edges with airtightness. As can be seen from FIG. 8, since the whole is almost flat and has little catch, it is convenient to cover directly on a plant or on a frame made of a pipe standing on the plant. The agricultural net 7 plays the role of a shade for preventing the light of the LED 20 from leaking obliquely backward. Instead of the agricultural net 7, a fence net knitted from polyethylene or the like, which is generally used at construction sites, can be used.

  By the way, the agricultural net 7 of the present embodiment is formed by cutting a portion that becomes the mesh 70 from the soft PVC sheet, but the LED lamp can be used as it is without making the mesh 70 (not shown). It is possible to provide a lighting device with a shade in open field cultivation and house cultivation according to the present invention, in which an agricultural sheet is integrated.

  In this embodiment, the state of use is shown in FIG. 9, but the clip 8 is used to attach the tape-shaped LED lamp 14 to a column, rope, net or the like while providing light shielding properties thereto. This clip 8 has a shape similar to a binding clip used for bundling electric wires and the like, and a sphere 83 is provided at each end of both arm portions 82 and 82 of a deformed Ω shape made of nylon 66. It has a shape. When the arm portions 82 and 82 are twisted with the two spheres 83 and 83, the arm portions 82 and 82 are crossed to form a dharma-shaped ring 80, but the two spheres 83 and 83 interfere with each other. Therefore, the crossed state of the arm portions 82 and 82 cannot be solved naturally. On the other hand, the diameter of the thick part on the inner periphery of the Dalma-shaped ring 80 is narrower than the lateral width of the tape-shaped LED lamp 14, so that the tape-shaped LED lamp 14 is passed through the tape-shaped LED lamp 14. It is necessary to curve in the width (short) direction. That is, the tape-shaped LED lamp 14 is passed through the concave side toward the translucent layer 15, but steps 81, 81 (clamping portions) are provided on the inner periphery of the Dalma-shaped ring 80 in order to determine the position of the tape-shaped LED lamp 14. Here, both edge portions of the tape-shaped LED lamp 14 are conveniently hooked and clamped here. A thin portion on the inner periphery of the dharma ring 80 of the clip 8 is an attachment portion 84 for attachment to the rope R.

  The tape-shaped LED lamp 14 used for the clip 8 of the present embodiment has the LED 200 positioned on a flexible substrate 29 to form an LED string including wiring by surface mounting, and the front and back surfaces are made of silicone resin. The light-transmitting layer 15 on the front surface side and the black layer 16 on the back surface side are covered and are flexible as a whole. By the clip 8, the surface side of the black layer 16 is convexly curved and the surface side of the translucent layer 15 is concavely curved, so that the line of sight from obliquely behind can be blocked. This is a substantial shade.

  The present invention is not limited to the above-described embodiments, and various variations can be given within the scope of the idea. For example, the present invention can be provided as a set or set attached to an agricultural net used for insectproof, birdproof, windproof, etc., and these are also within the scope of the present invention. If it is necessary to further increase the strength in the longitudinal direction of the present invention, a reinforcing member such as a metal wire or carbon fiber wire may be provided in the longitudinal direction of the casing. Further, when providing a notch in the shade, it is also possible to provide a guide line for cutting by hand or making a notch with a cutter to make this notch. There is also a method in which the casing is passed through the casing without passing through the shade. In this case, the mounting tool is not directly related to the shade. For example, a laser diode can be used instead of the LED of the above-described embodiment.

  The present invention can be used on the surface of a pond or underwater such as a ginger or the ocean. This is because the light emitted from the semiconductor light emitting device is applied to the underwater animals and plants. It can also be used to purify water by growing specific microorganisms. In addition, it is possible to configure a protective light that emits yellow light. It prevents the damage of straw and promotes the growth of cultivated plants. In addition to yellow light, insecticides use yellow-green light. Even in such a case, it is important to reduce as much light as possible from the obliquely rear side of the lighting device. These are also within the scope of the present invention. The present invention has such a wide range of applications and brings great industrial benefits.
