How do LED Grow Lights Work?
LED grow lights are an artificial light source that uses LEDs (light-emitting diodes) as the light-emitting body to meet the light conditions required for plant photosynthesis. By type, it belongs to the third generation of plant supplemental light fixtures!
Why can LED plant grow lights help plants grow?
Light as a kind of energy, plants provide material and energy for their own growth and development through photosynthesis, which affects the formation of assimilation force, stomatal opening, enzyme activation, etc. in the process of photosynthesis. Light as an external signal affects many aspects of plant growth and development such as groundward and rightward, gene expression, and seed germination, so light is crucial to plant growth.
Effect of spectral range on plant growth
The color temperature and lumens of plant lights are seen from the human eye, while the photosynthesis of light by plants is not dependent on color temperature and lumens. The plant’s perception of light lies in the spectrum. Plants bathed in sunlight are not interested in all of the solar spectrum. The main influence on plants is visible light with wavelengths between 400 and 700 nm, a region of the spectrum often referred to as the effective energy region for photosynthesis.
280 ~ 315nm: minimal effect on morphological and physiological processes
315 ~ 400nm: little chlorophyll absorption, affecting the photoperiodic effect and preventing stem elongation
400 ~ 520nm (blue): the largest ratio of chlorophyll to carotenoid absorption, and the greatest impact on photosynthesis
520 ~ 610nm (green): the absorption of pigments is not high
610 ~ 720nm (red): low absorption of chlorophyll, significant effect on photosynthesis, and photoperiodic effect
720 ~ 1000nm: low absorption rate, stimulates cell lengthening and affects flowering and seed germination
>1000nm: converted into heat
Why do you need LED grow lights?
Light environment is one of the important physical environment factors indispensable for plant growth and development, and controlling plant morphology and establishment through light quality regulation is an important technology in the field of facility cultivation. In environments where there is a lack of daylight, these lights can act as daylight to enable plants to grow and develop normally or better. LED grow lights have the function of strengthening the roots, promoting growth, regulating flowering period and color, promoting fruit ripening and coloring, and improving taste and quality. LED grow lights have the function of environmental protection and energy-saving. LED grow lights provide photosynthesis to plants, promote plant growth, shorten the time used for flowering and fruiting, and improve production. In modern construction, it is indispensable for agricultural crops.
It is based on the influence of light on plants and their “preference” for light, LED grow lights use technology to achieve artificial light instead of sunlight. We can design light formulas for different plants according to their species to meet their light needs at different stages of growth, flowering, and fruiting. We are a LED grow lights manufacturer, please feel free to contact us if you need them.
