The band of the sun is divided according to the wavelength of the solar wave. According to the length of the wavelength, it can be divided into ultraviolet band, visible band and infrared band.
1. Wavelength is 200-370 nm (nanometer) band. It has strong penetration. It can reach the depth of human skin and cause skin melanin deposit, aging and fading.
2. The wavelength is 380-780 nm, which is a visible spectral band. It has no direct harm to human body.
3. The wavelength is 850-4000 nm. It has high heat.blob
This is a new type of plant growth supplement light, after application test, the plant light wavelength is very suitable for the growth of plants, flowering, results, plant growth light is the international leader in the use of semiconductor lighting principle, dedicated to flowers and vegetables in the production of high precision technology products.Generally, indoor plants and flowers are always getting worse and worse. The main reason is the lack of light irradiation. Through the LED lamp irradiation suitable for the spectrum required by plants, it can not only promote their growth, but also extend the flowering period and improve the quality of flowers. This high-efficiency light source system can be applied to greenhouse, greenhouse and other facilities in agricultural production. On the one hand, it can solve the disadvantages of insufficient sunlight that leads to the decline of the taste of greenhouse vegetables such as tomatoes and cucumbers. On the other hand, it can make the winter greenhouse jacket vegetables come to market before and after the Spring Festival, so as to achieve the power of anti-seasonal cultivation.Light of 400 ~ 520mm (blue) and 610 ~ 720nm (red) contributed the most to photosynthesis.Light at 520 ~ 610nm (green) is absorbed very little by plant pigments.Commercially available plant lamps offer both red and blue wavelengths of light, covering the range of wavelengths needed for photosynthesis. Visually, the lights are all pink.The following is the wavelength table of light emitted by LED of different colors: royal blue, royal blue, 445nm, 440nm~460mm blue, 470nm, 460~490nm, cyan, 505nm, 490~520nm, green, 530nm, 520~550nm, red, 627m, 620~645nmred-orange: 617nm 613~620nmAmber: amber 590nm 585~ 59nmFrom this table, we can easily find that the blue (470nm) and red (627nm) leds can provide the light needed by plants. Therefore, the ideal choice for LED plant lights is to use these two color combinations.
