(1) Luminous efficiency
Scientists are constantly working hard to increase the electro-optical conversion efficiency of every kind of electrical equipment, so that LED grow lights can achieve this performance. Under the same environmental illumination, LED grow lights consume less energy and can give plants better growth. .
The LED grow light has the characteristics of energy saving and environmental protection and is really loved by thousands of people, but mankind has never stopped the pace of progress.
Starting from the needs of plants, the luminous efficiency of LED grow lights is more important. Plant growth is not suitable for all spectra. They only absorb what they need. This requires us to produce LED grows from Starting from the actual needs of plant growth, it is best to provide the spectrum required for plant growth at that time for each growth stage of each plant.
(2) Uniformity of illumination
Every plant needs to receive light, and better every plant receives light and the light is even, otherwise some plants will grow poorly if there is insufficient light, and the other part grows normally, so if you want to make the plant grow better, then the light is even The uniformity of illumination must be maintained. The uniformity of illumination can be divided into the uniformity of the distribution of different light wave band chips in the LED grow growth lamp and the distance distribution between the LED grow lamps.
The chip distribution is generally based on the LED grow light supplement light plant characteristics. After the lamp bead ratio is obtained, how to intersect the chips is calculated, and finally distributed in the grow light according to a certain rule and packaged on the COB panel, making a single unit LED grow lights illuminate the main area with uniform light quality and light intensity distribution.
The arrangement of the spacing between the LED grow lights is mainly determined according to the light intensity of the edge of a single LED grow light, combined with a reasonable installation height to ensure the uniformity of light during large-area planting.
(3) Reliability of heat dissipation
Low-power LED grow lights do not need to take special heat dissipation measures, and only need to do a basic heat dissipation structure, because the prerequisite for low heat generated by LED grow lights is low power, but high-power LED grow lights are different, although relatively For traditional plant lights, the heat generated is reduced a lot, but compared to the grow lights and plants, long-term use will not only cause great damage to the lamps, but also have the risk of burning plants when exposed to close distances, so It is still necessary to take special heat dissipation measures.
Reliable heat dissipation performance can bring us convenience in the following aspects:
Relatively prolong the service life of LED grow lights, the service life of LED grow lights is about 50,000 hours.
The effective heat dissipation configuration of LED grow lights can also help control the ambient temperature. If heat dissipation measures are not taken for the grow lights, the local temperature around the lamp will be slightly higher for a long time, and the growth state of the plant will definitely be different from other places, which is not conducive to The overall temperature control of the greenhouse or plant factory.
When purchasing LED high-power grow lights, the reliability of heat dissipation is a very important technical indicator, which will have a direct and serious impact on the yield and quality of later planted crops.
(4) Rationality of light distribution
The LED grow light chip plays a direct role in supplementing light for plants. It can be said that the light of the LED grow light is based on the chip.
The light distribution includes the chip spectrum and the chip matching. The chip spectrum is the light-emitting band after the chip is produced. The most important wavelength is between 610nm and 720nm, and the wavelength is between 400nm and 520nm. These two wavelengths are red and blue. Can promote plant photosynthesis, mainly affect the flowering and fruiting of plants.
In fact, it is the ratio of red and blue lamp beads of LED grow lights. At present, everyone refers to the data based on the ratio of sunlight spectrum, and adjusts flexibly according to the field planting situation and crop types and functions. The ratio of red to blue light of the sun is 6-8: 1 or so, people refer to this, flower foliage or leafy vegetable plants, the configuration is less than 6-8:1, let the blue light a little bit, blue light has a promoting effect on the growth of plant leaves. For flower viewing, choose 6-8:1 or more for supplementary light during the flowering period, so that there will be more red light, and red light has a significant effect on the flowering and fruiting of plants. For other growth stages, follow the sunlight reference ratio, and choose 6-7:1.
(5) Environmental suitability
As the name implies, LED grow lights can be used in a planting environment. What kind of performance is required to meet the requirements of various environments.
The environmental applicability of LED grow lights can be roughly analyzed from the planting area, plant characteristics and plant growth environment.
According to the size of the planting area, the main decision to use the shape of the LED grow light, the current LED plant light are square, round and foldable design. The square LED grow light is suitable for dense planting of plants in an area, maximizing the area and even light. The round LED grow light can illuminate a single plant in all areas of the plant in all directions, which not only meets the plant's demand for light supplement, but also reduces the waste of electricity and light energy. The foldable LED grow light is suitable for planting in a large area without wasting space and making the planting effect better.
According to the characteristics of plants, positive plants need to provide sufficient light during flowering/fruiting/rapid growth stages. At this time, LED high-power plant lights are often used to supplement light to meet their growth needs.
Depending on the type of plant, the growth environment of plants will have huge differences in light, air, nutrition, humidity, etc. You need to pay attention to it. For example, if you are doing hydroponics, the relative humidity of the environment will be higher, which requires plant lights to have Certain waterproof performance, the same in other environments.
Nothing is absolutely perfect. As a manufacturer of LED grow lights, what we have been doing is: discover the needs of users-meet the needs of users-feedback from users-solve problems encountered by users --Provide better products and services--Provide users with better LED object lights, and provide better light environment for plants.
