LED plant growth lamp is a kind of artificial light source that uses LED (light-emitting diode) as light body to meet the lighting conditions required by plant photosynthesis. According to the type, belongs to the third generation of plant light lamps!
In the absence of sunlight, this lamp can act as sunlight, so that the plant can grow normally or better.
This KIND OF LAMP HAS STRONG roots, encourage, adjust the flowering period, color, promote fruit ripening, color, enhance the taste and quality of the role!
Light environment is one of the indispensable physical environment factors for plant growth and development. It is an important technology in the field of facility cultivation to control plant morphogenesis through light quality regulation. Plant growth lamp more has the effect of environmental protection and energy saving, LED plant lamp to provide photosynthesis for plants, promote plant growth, reduce the time of plant flowering and fruit, improve production! In the modernization, it is indispensable for crops. LED plant growth lamp has the following main technical points:
Picture
Color temperature and lumen of plant lamp
The color temperature and lumen of the plant lamp are seen by the human eye, and the photosynthesis of the plant to the light is not seen by the color temperature and lumen.
Picture
Effect of spectral range on plant growth
280 ~ 315nm: minimal impact on morphological and physiological processes
315 ~ 400nm: less chlorophyll absorption affects the photoperiod effect and prevents stem elongation
400 ~ 520nm (blue) : chlorophyll and carotenoid absorption ratio is the largest, which has the greatest impact on photosynthesis
520 ~ 610nm (green) : the absorption rate of pigment is not high
610 ~ 720nm (red) : low chlorophyll absorption rate, which has a significant impact on photosynthesis and photoperiod effect
720 ~ 1000nm: low absorption rate, stimulating cell elongation, affecting flowering and seed germination
> 1000nm: converted to heat
Photosynthetic Photon Flux (PPF) refers to the number of micromoles of photons emitted by artificial light sources per second in the wavelength band of 400-700nm, in umol/s. The PPF value measures both the total value of the lamp and the component at each interval of 100nm. This is because it is necessary to obtain the total PPF of the lamp, but also to understand the components of different wavelengths, that is, the light formula; It can only be measured using an integral sphere designed to test plant growth lamps
