    Abstract: In a plant growing system, a first light source irradiates a plant with light having a peak wavelength in a range from 380 to 560 nm and a peak wavelength in a range from 560 to 680 nm and a second light source irradiates the plant with far-red light having a peak wavelength in a range from 685 to 780 nm. Further, a control unit controls the first and the second light source to perform respective irradiation operations and a time setting unit sets a first and a second time zone in which the control unit controls the first and the second light source to perform the respective irradiation operations. The first time zone ranges from a first predetermined time before sunset to a second predetermined time after sunset, and the second time zone starts after the first light source completes its irradiation operation.

  • Publication number: 20150128490
    Abstract: An improved method to produce artificial light for plant cultivation, an illumination device with a semiconductor light emission solution and device suited for plant cultivation in a greenhouse and/or dark growth chamber environment are described. The best mode is considered to be a lighting device with LEDs that produces an emission spectrum similar to the photosynthetically active radiation (PAR) spectrum in a dark growth chamber. The methods and arrangements allow more precise spectral tuning of the emission spectrum for lights used in plant (310, 311) cultivation. Therefore unexpected improvements in the photomorphogenetic control of plant growth, and further improvements in plant production, especially in dark growth chambers, such as basements, are realized.

  • Publication number: 20140123554
    Abstract: A physical method for maintaining the freshness of vegetables and fruits via the technology of the optical signal and optical signal generator are disclosed. By adopting the computer programmable pulsed scanning signal generator, it controls the light-emitting device mounted with red, green and blue light sources group to generate optical signal with pulsed or pulsed periodical scanning combined spectrum. The optical signal irradiates the fresh-cut fruits and vegetables preserved in the storage assembly at room temperature or at controlled temperature and humidity. By regulating the optical signal with periodical pulsed spectrum or pulsed scanning spectrum or periodical pulsed scanning combined spectrum, the irradiated vegetables and fruits obtain photon energy needed in light reactions of photosynthesis from the lighting environment of artificial optical signal which is in bright and dark periodic variation.

  • Publication number: 20140090293
    Abstract: Agribusiness like most markets is very competitive. In particular, agricultural products that have a short shelf life create an added pressure to sell and ship more quickly. By using mirrors and other reflective material, the cost of production is reduced, while improving the quality and quantity of plant production. This process of using mirrors and reflective material improves plant growth and production beyond other indoor or outdoor growing systems. This process may be the most efficient system by growing plants in a sterile, pesticide-free, and easily accessible facility, significantly reducing labor costs. By controlling every facet of the growing process, commercial production can occur in virtually any kind of outdoor weather conditions, while making best use of land and natural resources, potentially affecting agribusiness globally. Because this process has national and global consequences, the use of mirrors and reflective material for plant production needs to be patented.

    Abstract: The present invention provides an illuminating device that makes it possible to reduce the number of members for regulating a polarization state and can irradiate light having natural color shades without decreasing energy efficiency of light irradiation, and a plant growth regulation method using the illuminating device. The illuminating device of the present invention includes a light-emitting light source and a polarization state regulation member that regulates a polarization state of the light-emitting light source, in which the polarization state of a wavelength region of a portion of emission wavelengths is changed to circular polarization, and a degree of circular polarization of light in a wavelength band for regulation among the light rays to be irradiated is 0.3 or higher. In a preferable embodiment, a width of at least one wavelength band for regulation of the polarization state regulation member is from 60 nm to 250 nm.

  • Publication number: 20130298459
    Abstract: The system of the indention is applied to sunless enclosed spaces suitable for agricultural use. A growing zone is seeded with a particular crop variety. The crop growth is optimized by receipt of a specific light emissions. A light emitting computer comprising an array of light emitting devices, a microprocessor, a radio frequency receiver and a storage device is disposed optimally over the growing zone to bath the zone uniformly in the specific light emission for optimal growth. A radio frequency identification tag is placed within the growing zone to electrically define the growth zone for the light emitting computer. The RFID tags emit a crop variety specific radio frequency that is received by the radio frequency receiver. The appropriate light emission profile related to the radio frequency is retrieved from a digital look-up table. The emitting computer then emits the light emission profile.

    Abstract: Method and lighting device for providing artificial light optimally to plants is achieved effectively by moving both the lighting device (2, 3 and 4) and its emission pattern to maximize incident light on the plants (5, 6 and 7) being cultivated. The horticultural lighting device illuminates plants so that the lighting device is moved vertically and at least one light emitter (3 and 4) and/or reflector (2) is rotated to maximize light exposure from the lighting device on the plants (5, 6 and 7). In the best mode the movable and rotatable lighting device is used to grow very high plants. The lighting device (2, 3 and 4) is moved by a motor programmed to change the position of the lighting device and the orientation of the emission pattern in accordance with the growth cycle of the plants in the greenhouse (350) to maximize incident flux on the plants.
