LED grow light color are orange,red and blue or a full with white,a small amount of infrared or ultraviolet sterilization, promote the photosynthesis of plants, also called nutrition lights, plant growth lamp. Led aquarium lamp ledaquariumlight is mainly Lan Baiguang, blue light to simulate the moonlight, irradiation coral. Plants and corals to provide the needs of the growth of the artificial nature of the sun in the need to provide nutrients. However, would like to remind that the wavelength of the light is suitable for plant growth is special, do not think that as long as it is red and blue can be irradiated plants, not to make the red and blue light is to make the plant lights. Because not all plants can be used as a light plant, bad plants The loss outweighs the gain. In addition, the green light is suitable for the sleep of plants.
Scientists have found that the blue region and the red region is very close to the efficiency of plant photosynthesis curve, is the best source of plant growth. General indoor raising flowers and plants, always raise more and more poor, main reason is the lack of light irradiation, by suitable for plant required spectrum of LED light irradiation can not only promote the growth of the, but also to extend the flowering period and improve flower quality. Such as life cycle only a day or two of the flower, under the irradiation of the LED lamp, florescence can extended to 20 days led plant growth lamp power is small, but high efficiency, because the light emitted by the full spectrum, that is to say seven kinds of colors, and plants need but only the red and blue light, so most of the traditional lamp light waste, so the efficiency is very low. And led plant growth lamp can emit plants need specific red and blue, so efficiency is very high, which is why plant led grow light a few watts of power than tens of watts or even hundreds of watts of light effect is better. Another reason is that the traditional sodium lamp MH spectrum inside the lack of blue light, mercury lamp and energy-saving lamp spectra and lack of red, so traditional fill light effect are compared with the LED lamp a lot worse, and compared with the traditional lamp to more than 90% of the electric energy is saved, the operation cost is greatly reduced. (excerpt) red and blue light specific wavelength light source, determines the suitable for plant growth.
Now generally used in the indoor pot planting, greenhouse cultivation, breeding, and change the plant flowering, flower planting, the night landscape lighting. Many American customers are used to grow medical “aunt”. Special lighting in foreign countries, led plant lights are very popular. Although the central illuminance value without the sun so direct, but in the interior, LED lamps light than the general utility. 100W LED lamps is equivalent to about 250W high pressure sodium lamp, energy saving is necessary, that is a little expensive, but with customers the delicate crops or coral than, also insufficient for weakness: plant light regulating plant growth is generally the greenhouse to regulate growth rhythm, promote early, early flowering. Greenhouse is characterized by high temperature and humidity, the temperature of the day to 4~50 degrees is very common, humidity of nearly 100%. To promote the plant results of LED, semiconductor element is to pay attention to a grim challenge: but I want to remind you friends of the flowers and not all plants are suitable for plant lights shine, plant lights really can promote the growth of plant roots, leaves and stems, change and promote plant flowering period. But it’s not good to. Generally recommended for use in the interior need to add light to the plants, and do not leave the plant near, so as not to heat up too fast, burn plants.
