Do you know these knowledge points of plant growth lamps?

1. The led grow light full spectrum market from 2018 to 2020 is mainly affected by the rapid growth of the hemp market. At the same time, the direction of the professional market has also evolved from Indoor (indoor) to Greenhouse (greenhouse).
2. The brand-only theory of lamp bead chips is not the healthy development direction of plant planting. After the lamp bead efficiency reaches 2.0, the blind pursuit of parameter improvement will not be of great significance to planting.
3. To make a plant light, you must first know what "light" is. The response between light energy and receptors is what needs to be studied for plant cultivation.
4. There is no best spectrum, only the most suitable. On the basis of certain light quality conditions, light quantity>light quality, which means that the spectrum is the same, and the planting effect will be improved after increasing the power. However, one of the major advantages of LED plant lights is energy saving. For practical applications, LED plant growth lights can maximize plant absorption efficiency and minimize energy waste.
5. Plants are highly adaptable (the difference between animals is that animals have mobility), the first and second generations will show differences, so in this case, the requirements for lighting on the planting environment will be different.
6. The equipment has parameter attributes. It is unreliable to evaluate the quality of plant lights based on self-feeling without parameters and light color.
7. Plant light spectrum technology-planting technology spectrum technology (core technology)-planting conditions
Quantity of light-PPFD of the canopy
Light quality-SPD, spectral form
Light cycle-bright cycle, dark cycle
8. Only by mastering DLA can we discuss planting technology, and only with stable planting technology can we realize planting industrialization.
9. The difference between DLA and DLI:
(1) DLI-Sunlight Dose-Geographical Location
(2) DLA-artificial light dose-light source design
Calculation formula: DLA=0.0036 X PPFD X photoperiod (hour) [Unit: mol/m2d]
10. The energy supply method has changed the traditional planting process, and planting quality and planting cycle have become goals.
11. Three elements of planting technology spectrum technology:
Germplasm (object)-DLA (energy)-environment (condition)
Under the same germplasm and the same environment, the least spectral components are the best. Energy saving! The highest energy efficiency!
12. Plants absorb only 13% of sunlight, and the green light band of sunlight is sufficient. If it is a greenhouse to fill light, when the plant lamp is designed, the spectral composition may not contain the green light band, so that it can also save energy Consumption.
13. Light has no color, and white light does not exist.
