Recently, a Japanese plant factories began to use red, blue, green, RGB LED light source to light up the vegetables cultivated. According to the test, the vegetables grown in the way is more nutritious than the vegetables grown under the sun light. According to the scientists explained, because the LED lighting can regulate the wavelength of and brightness of the light, so it is more adapted to the needs of vegetable growth. Typically, are the main colors of the light that is necessary for plant growth are red and blue, the ratio is generally from 10:1 to 5:1. The sunlight contains a lot of ultraviolet and infrared, if exposed under the sun for too long time, which will also affect the normal growth of plants. The main advantage of LED lighting is that you can control the wavelength of light and brightness, but also be able to "pulse irradiation." The so-called "pulse irradiation" refers approach that is adopted to release high-speed light by switching LED power, which is similar to flash. the principle of "Pulse irradiation," is between the bright and dark to allow the plants to get more time to rest. Because plants is the same as the people and also need to rest so that recharge their batteries in order to make better growing. According to Japanese research data showed that the frequency of "pulse irradiation" shading remained at 1:2 / h, which is the highest rate for plants’ growth, 33% higher than the ordinary. Just use the "pulse irradiation," can make that the volume of vegetables grown increases 20-25%. And by adjusting the color and intensity of the LED light source, the vitamin content of the vegetables grown can reached more 1300% than the those of ordinary vegetables. such as leaf lettuce grown, , the content of the vitamin A, C, E respectively increase more 14 times, 3 times and 6 times than the unusual. Meanwhile, the "pulse irradiation" also saves electricity, preliminary estimates that the cost of production of vegetables has been let down refrain. Accordingly, scientists believe that LED lighting has a huge market space in the plant in the future. Japan applied LED lighting to grown vegetable ,which is worthy of a good way that not only both make vegetable vegetables grow faster, but also increase the nutrition of the vegetable, because the spectral characteristics of LED lighting, LED lighting can be well combined with plants to bring us a lot easier life, nowadays, the LED lighting has enjoyed a great popularity in our lives, most notably is the LED flood light as outdoor decoration and landscape lighting and LED tunnel light which is widely used to ensure traffic safety in tunnel, the highly integrated high brightness COB is adopted as the light source of LED floodlights and LED tunnel light to make sure that adequate lighting efficiency outdoor light,the low pressure constant drive is used to convert the AC into DC to significantly rise the electrical energy utilization and reduce the eye stroboscopic effects stimulating the human eye, the lampshades are covered with the quality tempered glass, which has the advantage of high temperature resistance, impact resistance, high definition so that fully qualified for the outdoor temperature and dusty environments, login www.lead-lighting.com/products/bid32-1.htm for more features of LED Tunnel light or return home to get other quality professional LED lighting.
