Description

Greenhouse lighting equipment{LIGHTING FIXTURES FOR GREENHOUSE}

The present invention relates to a lighting device for a greenhouse, and more particularly, by irradiating light into one area of a greenhouse to harvest fruit trees, separate them and irradiate light to the other area to harvest fruit trees, and adjust the irradiation angle of light to harvest fruit trees. It relates to a lighting device for a greenhouse that can be easily harvested.

As is well known, a greenhouse is a building made to artificially control light rays, temperature, humidity, etc., which are the main growing environments of plants.

Greenhouses are capable of stimulating and suppressive cultivation of crops, so that they can continuously produce agricultural products throughout the year. High profits can be made in the area, and it is widely used for cross breeding by freely controlling the growth stages of various crops, and the relationship between the environment and crop growth is investigated by controlling the temperature, humidity, and light to investigate the reaction of the crops. It has economic, academic, and educational purposes, such as being able to research and using it as an educational facility by protecting and nurturing tropical and subtropical plants.

These greenhouses include glass rooms and green houses with heating devices. Among them, green houses have developed rapidly and are now widely used nationwide as the most important horticultural facilities, and are most often used for cultivation of vegetables, flowers and fruits. It is also used for cultivation of fruit trees.

Greenhouses mainly use polyethylene film as a covering material. In addition, vinyl acetate film and the like are also used, but the transmittance of sunlight is almost the same, but there is a big difference in the transmission of long-wavelength hot rays. The highest transmittance is polyethylene film and the lowest one is vinyl chloride film, so if you consider the warmth at night, vinyl chloride film is much more advantageous than polyethylene film.

Since the green house is light in the covering material, the skeleton material is greatly reduced compared to the glass greenhouse, and the construction cost is greatly reduced, so the facility area is increasing. In the past, bamboo or wood was used, but in recent years, iron pipes, iron materials, and hard PVC pipes are widely used.

As described above, when fruit trees grown in a green house are harvested between April and September, the inside of the green house is hot throughout the afternoon to create a poor environment. There was a problem that the dawn that can visually confirm is limited to between 5 a.m. and 8 a.m. and 5 to 8 p.m. In other words, certain fruit trees including melon, etc. are harvested from midnight to early morning when the temperature is cool, and the quality is superior and the period to maintain freshness is longer than when it is not. Therefore, the harvest rate of fruit trees is poor, and it is difficult to harvest fruit trees having excellent quality and freshness.

As a conventional technology for solving such inconvenience, Korean Patent Registration No. 1892541 (Registration Date August 22, 2018)'Greenhouse Lighting Device' and Korean Registration Patent No. 1980489 (Registration Date May 14, 2019) A'lighting device for harvesting melon' is disclosed.

However, the above-described prior art has problems in that the frame for supporting the lighting is made of the same or similar size as the width of the greenhouse, so that the volume is increased, transportation is cumbersome, and installation time is required.

In addition, since the above-described prior art cannot adjust the irradiation angle of the light source, there is a problem in that light cannot be irradiated to each desired area in the greenhouse for harvesting fruit trees.
