The Quanzhou LED technology center developed a light source for plant growth

Recently, the in Quanzhou LED industry technology innovation strategic alliance technology center, the staff tried to environmental protection and energy saving LED light source for plant lighting, and has achieved initial success. Processing technology, under the appropriate wavelength LED light source, the growth rate and survival rate of plants is expected to improve to 20-50% and about 30% of the energy savings.Currently make up for the lack of sunlight in the greenhouse, greenhouse cultivation, with the light source is generally fluorescent, high pressure sodium and incandescent light source spectral energy distribution is based on the needs of the human eye to light, does not comply with the plant growth .Plant photosynthesis, light wavelength 400-700nm, and blue (470nm) and red (630nm) LED, just to provide light for plants, the former can promote green leafy growth, which helps to bear fruit and extend the flowering period. LED lights through the development of suitable plant the required spectra, not only may issue a narrow light waves of monochromatic light, and any combination of the different needs according to the flora and fauna.LED light irradiation for plant-available spectrum, can not only promote their growth and improve the fruits quality, to ensure that the greenhouse vegetable taste-season to cultivate, but also greatly reduce the cost of plant breeding, LED plant growth lamps have a higher photoelectric conversion efficiency power consumption is 1/4 of the fluorescent lamp, sodium lamp 1/10. If the LED alternative to traditional electric light plant Seedling Nursery, its one-time total market size will reach 200 billion yuan.
