Where are the LED grow lighting mainly applied


Over the past decade, the LED lighting has developed rapidly, how to use the artificial light to control the growth of plant namely light environment control lighting technology has attracted attention. LED grow lighting technology as plant lighting is mainly used in two ways:
First of all, LED grow lighting as supplemental lighting for the plant photosynthesis when there is less sunshine;
Second, illumination induced for the plant light cycle, morphogenesis.
1, the traditional light source generates too much heat, such as the use of LED grow lighting and supplemental hydroponic systems, air can be reused and the excessive heat and moisture may be removed, the energy can be efficiently converted to photosynthetically active radiation, and ultimately converted into plant matter. Studies have shown that: thanks to the use of LED grow lighting, the growth rate of lettuce and photosynthetic rates have increased by more than 20%, the LED grow lighting for plant factory is feasible.
Compared with fluorescent lamps?the study found that LED grow lighting source with mixed wavelength, can significantly promote the growth of spinach, radishes and lettuce, improve morphological indicators; enables the largest bioaccumulation of beet?as well as the most significant accumulation of beet pigment and produce the most accumulation of sugar and starch in roots.
Compared with metal halide lamps, for pepper, basil plants growing under the LED grow lighting, there is a significant change leaf anatomy form, and with the increase in optical density?there is dramatically increasing in plant photosynthetic rate. LED grow lighting with composite wavelength can cause the increase in the number of stomata of marigold and sage.
2, induced illumination for the cycle and morphogenesis of plants,
LED grow lighting with specific wavelength can affect flowering time of plants, quality and flowering duration. LED grow lighting with certain wavelengths can increase the number of flower buds and flowering of plants; some LED grow lighting can reduce flowering response, the regulation of the peduncle length and flowering, helping the flowers advance into the market. This shows that the regulation of LED grow lighting attribute to the flowering and subsequent growth of plants.
3, aerospace research ecological life support system
Establishment of Controlled Ecological Life Support System (CELSS) is the fundamental way to solve how to support the long-term manned space life, the cultivation of higher plants is an important element for CELSS, the key to one of which is light.
Based on the special requirements of the space environment, the light source used in the cultivation of higher plants space must have a high luminous efficiency, light output is suitable for plant photosynthesis and morphogenesis, known as small size, light weight, long life, high safety and reliability record and no environmental pollution. Compared with cool white fluorescent lamps, high pressure sodium and metal halide lamps and other light sources, LED grow lighting can more efficiently converted the photosynthetically into the active radiation; addition, it has a long lifespan, small size, light weight and other characteristics, so LED grow lighting is enjoying a great popularity in the cultivation of plants in the ground and in space in recent years. Studies have shown that LED grow lighting system can provide illumination whose spectral energy evenly distribute? the energy conversion efficiency of light needed for plants is 520 times over the metal halide.
