The Characteristics and Advantages Analysis of LED Grow Lights
First, I want to share a funny story about the radish and light with all. Long long ago, in order to found a boyfriend, the radish had to lose weight everyday .And one day the LED grow lights became she's boyfriend, they are very happy to live together. However, the radish had been growing in weight since the lights became she’s boyfriend .And the weight from the 1 pound to 5 pounds, the radish thought she was really fat and was considering whether to break up with the grow light. . . . . .
After sharing a simple but funny story, we are entering the topic
一：The Characteristics of LED Grow Lights
1.The effects of light wavelengths on the photosynthesis of plants are different. The light required for photosynthesis of plants has a wavelength of about 400-700 nm. The 400-500 nm (blue) light and 610-720 nm (red) contribute the most to photosynthesis.
2.Blue (470nm) and red (630nm) LED, just provide the light required by the plant, so the ideal choice is to use these two color combinations. In terms of visual effects, the red and blue combination plant lights appear pink.
3.Blue light helps plant photosynthesis promote green leaf growth, protein synthesis, and fruit formation. Red light promotes plant rhizome growth, helps flowering and prolongs flowering, and increases yield.
4.The ratio of red and blue chips of LED plant lights is between 4:1 and 9:1, usually 6-9:1.
5.When the plants light is used to fill the plants, the height of the leaves is generally about 0.5-1 meters. Continuous irradiation for 12-16 hours every day can completely replace sunlight.
6.The effect is very significant, the growth rate is nearly three times faster than the natural growth of plants.
7.To solve the problem of lack of sunlight in winter in greenhouses, promote the chlorophyll, anthocyanin and carotene needed for photosynthesis of plants, harvest fruits and vegetables 20% earlier, increase the yield by 3 to 50%, and increase the sweetness of fruits and vegetables. And reduce pests and diseases.
8.LED grow light source, also known as a semiconductor light source, this light source wavelength is relatively narrow, can emit a specific wavelength of light, so it can control the color of light. Using it alone to irradiate plants can improve plant species.
9.LED plant growing lamp power is small, but the efficiency is very high, because other lights emit full spectrum, that is to say there are 7 colors, and plants need only red and blue light, so most of the traditional light energy Wasted, so the efficiency is extremely low. The LED plant grow lights can emit specific red light and blue light that the plants need, so the efficiency is very high, which is why the power of a few watts of the LED plant grow lights is better than the power of several tens of watts or even several hundred watts of power. Another reason is the lack of blue light in the traditional sodium lamp spectrum, and the lack of red light in the mercury lamp and energy-saving lamp spectrum, so the traditional light-filling effect is much worse than the LED lamp, and compared to the traditional lamp to save more than 90% of energy, run The cost is greatly reduced.
二：The Advantages of LED Grow Lights:
1. No standard outlet connector for a drive or cooling fan is required.
2. The environment of red blue wavelengths is required for the growth of plants.
3. Compared with other general lighting equipment, the LED plant light line is gentle and does not burn the seedling plants.
4.Compared with other plant lights can save 10% to 20% of the electricity.
5.Blue light can promote plant height, and red light results in plant flowering.
Finally, may be we can guess whether the radish has broke up with the grow light?
