Features of Full Spectrum LEDs

Full-spectrum LEDs greatly enhance the continuity and integrity of the spectrum by complementing the missing short-wave purple, cyan, short-wave green, and long-wave red parts of the spectrum, making the color gamut wider and closer to the full spectrum of sunlight.

Features of Full Spectrum LEDs

Short-wave "violet light" helps the human body synthesize vitamin D and promote the body's absorption of calcium. The violet light with a wavelength of 400? 420nm also helps plants form anthocyanins and resist the elongation of branches and leaves. Long-wave "red light" can promote the overall growth of plants during the flowering and fruiting stages.

The blue light band in the ordinary LED spectrum is relatively large, and excessive blue light and improper use of lighting fixtures can cause visual damage. Blue light suppresses the secretion of melatonin, which may lead to insomnia. Full-spectrum LED lamps can not only effectively reduce the blue light hazard of lighting LED light sources.

The wavelength of 280-315nm is already ultraviolet light, which has the function of directly suppressing the growth of various animals, plants and even fungi; the light wave of 315-400nm is also far-ultraviolet light, which absorbs less chlorophyll and prevents stem elongation; 400-520nm ( Blue) wavelength can directly make plant roots and stems develop, has the largest absorption ratio of chlorophyll and carotenoids, and has the greatest impact on photosynthesis; 520-610nm (green) The absorption rate of green pigments is not high; 610-720nm (red) It has a significant impact on photosynthesis and plant growth speed; wavelengths such as 720-1000nm belong to infrared wavelengths, which have low absorption rates for plants and can directly stimulate cell extension, which will affect flowering and seed germination; >1000nm--> is close to the thunder The wavelength of the emitted light has been converted into heat.

In addition, full-spectrum LEDs contain a small amount of ultraviolet light, which can effectively prevent pests and diseases.

The previous plant lights were mostly red-blue combination, all-blue, and all-red, which were used to cover the wavelength range required by plants for photosynthesis. In recent years, full-spectrum LED grow lights have become popular.
