What are the possible causes of “ineffective” the plant light?
① Irradiation distance
Many small partners will wonder: how far away should the lamp be from the plant? Is it possible to fill in the light wherever it hits?
In fact, the irradiation distance also determines the intensity of the light, and it is not “illuminated”. In the instructions for the use of general plant fill light, the irradiation distance reference is given, which can be adjusted according to the PPFD value of their own plants.
② Focus light and do not astigmatism
Although artificial light can simulate the solar spectrum, but can not completely replace the intensity of sunlight, so the limited light gathered on the plant, in order to reduce the loss of light energy and electric energy, faster to achieve the desired effect, which is why the same wattage, the same time, the effect is different.
To determine whether the light is focused, you can observe whether the light has a clear edge. At present, the “concentrating lens” is an effective optical technology for focusing the light, to achieve the purpose of improving the PPFD photon flux density, light intensity and uniformity, so as to meet the photosynthetic needs of plants faster.
“Full spectrum” is not universal
Plant fill light is mainly divided into full spectrum and red and blue spectrum, many small partners mistakenly believe that the full spectrum desk lamp and full spectrum ceiling lamp bought at home are the same
Although they are named the same, the full spectrum is not a fixed spectrum, for example, the full spectrum plant lamp has more green light energy, the red peak wavelength is 660nm, and the red peak wavelength of the ordinary white lamp is about 610nm, which is not suitable for plant growth.
④ “internal work” is not enough light decay serious
Those who have used the plant fill light lamp know that the fill light lamp has a long time and a large heat, the LED chip is easier to age, and it is gradually not bright, which is light failure, the PPFD value is decreased, the plant photosynthesis efficiency is reduced, and the effect and life are only “flash in the pan”.
When we choose the lamp, we can pay more attention to heat dissipation, and if there is a patented heat dissipation technology, it will be more guaranteed.
⑤ Imagine business promotion
For example, businesses in the promotion of 10 watts of light equivalent to 100 watts incandescent lamp, may be the best in the same power of plant light, but do not think that 10 watts can really replace the effect of 100 watts, is unable to achieve the desired effect.
