Among them, vinyl houses have developed rapidly and are currently the most important horticultural facilities widely used in the whole country and are most widely used for the cultivation of vegetables. Flowers, flowers, (Fruit trees) are also used for cultivation.

The vinyl house mainly uses a polyethylene film as a covering material. In addition, a vinyl acetate film and the like are also used, but the transmittance of daylight is almost the same, but there is a large difference in the transmission of heat ray having a long wavelength. The highest transmittance is the polyethylene film, and the lowest is the vinyl chloride film, so the vinyl chloride film is much more advantageous than the polyethylene film considering the nighttime warming.

Since vinyl house is lightweight, skeleton material is greatly reduced compared to glass greenhouse, and construction cost is greatly reduced. In the past, bamboo and wood were used, but in recent years, iron pipes, steel pipes, and rigid PVC pipes have been widely used.

As described above, when harvesting the grains cultivated in greenhouses from April to September, the inside of the greenhouse becomes hot during the afternoon and forms a poor environment, so that the time available for harvesting is lower than that in the afternoon, Which is visually confirmed, was limited to 5:00 to 8:00 in the morning and 5:00 to 8:00 in the evening. That is, the specific grains including melon and the like are harvested from the coolest midnight to early morning time, and the quality is excellent and the period of maintaining the freshness is prolonged. Therefore, it is difficult to harvest the high quality of fresh water and the freshness of the fresh water.

In order to solve the above problems, there has been proposed a solar cell in which a lighting facility is installed in a vinyl house, a solar cell, a planar heating element utilizing the solar cell and an LED ≪ / RTI > discloses a vinyl house having light.

However, in the conventional art, the LED light is installed in the center of the ceiling of the vinyl house, on the left and right sides, or on the cultivation shelf to provide artificial light necessary for cultivation of the crop, There was a problem.

Further, in the related art, the LED lighting is fixed to the center of the ceiling of the vinyl house, the left and right sides thereof, or the cultivation shelf. When the vinyl house is formed long in the back and forth direction, Which leads to an increase in installation and management costs.
