Nine characteristics of Yaorong LED plant light
LED plant light is a kind of plant growth lamp, which is a plant growth lamp made of LED (light emitting diode) material.
The plant growth lamp is a light source that adopts artificial supplementary light measures when the natural light is insufficient during the growth process of the plant. Fluorescent lamps and sodium lamps are widely used, but because of the light efficiency and pollution, they are gradually being used by LED plant growth lamps. Replaced.
Research on LED as supplementary lighting for plant photosynthesis. Traditional artificial light sources generate too much heat. For example, LED plant growth lights are used to supplement lighting and hydroponic systems. Air can be recycled, excess heat and water can be removed, and electricity It can be quickly transformed into effective photosynthetic radiation, and finally into plant matter. Studies have shown that the use of LED lighting can increase the growth rate and photosynthesis rate of lettuce by more than 20%, and it is feasible to use LEDs in plant factories.
Compared with fluorescent lamps, LED plant light sources with mixed wavelengths can significantly promote the growth and development of spinach, radish and lettuce, and improve morphological indicators; it can maximize the bioaccumulation of sugar beet, and the betatin accumulation in the hair root is the most significant, and it is in the hair root. Produces the highest sugar and starch accumulation.
Compared with the metal halide lamp, the anatomical morphology of the stems and leaves of the pepper and perilla plants grown under the LED plant lamp with the corresponding wavelength has undergone significant changes, and as the optical density increases, the photosynthetic rate of the plants increases. .
Principle of LED grow light
It is made according to the principle of sunlight required for plant growth and photosynthesis. Plant photosynthesis is mainly based on absorbing red and blue light, and LED plant lights are mainly based on red and blue lamp beads.
In the case of insufficient light, plants will develop stunted, yellow leaves, and stop growing. If the corresponding artificial light supplement measures are not taken, it will directly bring huge economic losses. As a new type of light source for plants, LED plant lights can not only supplement light for plants, but also completely replace sunlight to provide plants with the necessary photosynthesis. The spectrum.
When using LED plant lights, you must first determine three points: one is that plants need supplementary light, the other is that plants are worth supplementing light, and the third is that plants are suitable for supplementing light with LED plant growth lights. Need to add light needless to say, almost all plant growth and photosynthesis require the participation of light, that is, almost all plants can use LED plant lights to fill light; plants worthy of supplementing light requires the plant itself to have a higher value or The future has a higher value, which is to engage in scientific research; suitable for using LED plant lights mainly refers to clusters of dwarf bead plants. If it is a tall and strong plant like adult yew, it is not very suitable to use LED plant growth lights to supplement light. If it is used to cultivate seedlings, it is also a good choice.
Features of LED grow lights
(1) High light conversion efficiency, energy saving and environmental protection
(2) LED plant growth lamps generate less heat, have relatively slow light decay, and have a service life of more than 50,000 hours
(3) Use LED plant lights to induce and adjust the photoperiod of plants, so that plants can grow in a controlled manner
(4) LED plant lights can provide plants with the wavelength range required for specific plant growth,
(5) LED plant lights can supplement light for plants with insufficient light and help plants grow normally
(6) The use of LED plant lights can make plants completely separated from the outdoors and realize indoor planting, which is of great significance to the space planting industry
(7) The LED plant light has a wide variety of wavelengths and can be made into the spectrum required by the plant that is consistent with the spectral range of the plant's light morphology.
(8) Use the spectrum provided by LED plant lights for flowering and fruiting plants to allow plants to perform photosynthesis, which can increase their yield and quality
(9) The use of LED plants in the nursery stage can effectively prevent plants from growing excessively
LED plant growth lights have opened up a new world in the field of plant lighting supplement light. Although many advantages are integrated, due to the current indoor planting technology and cost constraints, it is still in the budding stage. There are still many market and technical problems. To solve it.
