The main function of the LED grow light is to replace the sun to fill the grow with light, so it is more important for the LED grow light lighting technology, the following is a detailed analysis for you.
Spectral distribution
A large number of studies have shown that red light and blue light are the two most important spectra for grow growth. grows generally rely on the chlorophyll in the leaves to absorb the irradiated light, so the spectrum selection of the LED grow light can be customized according to the proportion. Generally, it is the irradiance of 400-500nm blue light and 600-700nm red light, and the spectral composition, range, peak wavelength and color temperature of the selected combination of grow lighting need to be determined.
Packaging technology
Good jade also needs gold to inlay. With a good LED grow growth lamp chip, of course, it also needs good accessories and a reasonable layout of the lines and parts in the LED grow growth lamp. The LED grow growth lamp of Yaorong Technology adopts cob technology. With the addition of lens and reflector, the light can be concentrated more efficiently to reach the highest efficiency.
Photoperiod
Illumination and specific spectral wavelengths significantly affect the growth and development of grows, and the photoperiod also has a profound impact on the growth and development of grows. Affect the flower bud differentiation, flower induction and floral differentiation, grow dormancy, vegetative growth and physiological differentiation of grows. Therefore, when using LED grow lights to illuminate grows, it is necessary to provide corresponding supplementary light for each cycle, so that the grows can grow better.
Chip performance
This is the core component of the LED grow growth lamp, which will directly affect the life of the LED grow growth lamp and the light supplement effect. Yaorong Technology’s LED grow growth lamp adopts the OSRAM/SAMSUNG imported brand lamp bead chip, which makes the performance better. To a comprehensive upgrade.
Illuminance
grows receive different light levels, which will directly affect grow growth and structural characteristics. As the illuminance increases, the photosynthetic rate will continue to rise until the light saturation point. The light intensity affects the morphological structure, flower bud differentiation and fruit yield of crops. Illumination affects the growth and development of crops, and the degree of impact varies with the types and characteristics of crops. Due to the different requirements of grows for illuminance, proper illuminance can give grows better growth.
Light uniformity
Because LED grow lights have strong directivity and may have uneven spatial light color distribution, in large-area growing occasions, the uniformity of radiation on the illuminated surface of the grow should also be investigated to obtain a high-quality uniform lighting environment.
Cooling technology
Heat dissipation is very important to electronic products. If the heat dissipation is not good, the internal circuit may be burnt directly, which will also affect the light decay of the lamp beads and shorten the service life of the LED grow growth lamp. The LED grow growth lamp of Yaorong Technology adopts a hollow design, and there is no problem in heat dissipation.
The common forms of LED grow lights are:
Bulbs, light bars, panel lights, light strips, downlights, light grids, etc.
The application areas of LED grow lights are:
grow tissue culture, leafy vegetable production, greenhouse light supplementation, grow factory, seedling factory, medicinal grow cultivation, edible fungus factory, algae cultivation, grow protection, space fruits and vegetables, flower cultivation, mosquito repellent, etc.
LED grow lighting formula elements for high-quality grow growth
1. Light intensity: grow growth is affected by light intensity (photosynthetic active radiation energy PAR and photosynthetic quantum flux PPF).
2. Light quality: different colors of light (wavelength) have a great influence on grow growth, so the light quality should be adjusted according to the growth needs of crops.
3. Uniformity of illumination: In horticultural production, stable and uniform artificial illumination is the prerequisite to ensure normal and stable production.
4. Light position: A suitable light position helps grows to absorb light and improve the efficiency of photosynthesis.
But in the process of using, we must pay attention to the use time of the LED grow light, proper use time and correct use method, so as to bring more unexpected effects.
grow supplement light is to replace the sun to supplement the light when the light is insufficient. Under normal conditions of sunlight, the grow can be supplemented with light for 5-6 hours in the morning and evening when the light conditions are weak. The sun can be used during the day. Add light to grows. If there is insufficient light on rainy or cloudy days, you can use LED grow lights all day long, but also pay attention to leave time for grows to rest at night.
When using LED grow lights, you should also pay attention to the light requirements of different types of grows. If it is a grow that loves light and requires a long time, you must pay attention to the light time when using LED grow lights.
For light-loving grows, it is necessary to use LED growth lights to supplement light for grows at 6:00-10:00 and 17:00-00:00, because 10:00--17:00 is the sunlight that meets their growth needs Time period, so it takes about 11 hours for the grows to fill in the light.
LED grow lights will generate a certain amount of heat. If they get too close, they will burn the grows and cause some damage to the grows. If the distance between the LED grow light and the grow is too far, it will greatly reduce the light utilization rate, thereby weakening the light supplement effect. If the heat of LED grow lights is less than other grow lights, but there will be a certain amount of heat. If the distance is too far, it will also affect the effect of fill light.
The effect of LED grow lights is very significant, and the growth rate is almost 3 times faster than that of ordinary grows that grow naturally. LED grow lights are generally suspended at a height of about 0.5-1 meters from the leaves, and they need to be continuously illuminated for 12-16 hours a day to completely replace the sun. In the winter when there is often no sunlight, the use of LED grow lights in greenhouses can also grow green vegetables, which can improve the sweetness of vegetables and fruits, reduce diseases and insect pests, and increase the yield by 30 to 50%.
