It is impossible to grow plants in greenhouses with sufficient light at every time period. Generally, in winter, there is less light. This will not only affect the growth cycle of plants, but also the plant yield will greatly decrease, and the planting benefits will change. low. However,yaorong LED grow lights can bring enough light for greenhouse planting.
The light source of yaorong LED grow light is mainly composed of red and blue light sources, and the main influences on plants are: blue light wavelengths 450-460nm and 460-470nm, red light wavelengths 620-630nm and 640-660nm. Red light can promote the metabolism of stems, and greatly promote the flowering and fruiting of plants. Blue light mainly prevents plants from growing, promotes the formation of plant dry matter, and has a significant effect on the growth of rhizomes.
In the case of insufficient light in the greenhouse, use yaorong LED grow lights to fill light, but you need to pay attention to:
1. The roof of greenhouses is cleaned regularly to clean the "roof garbage", otherwise the transparency is not enough, it will have a great impact on the light and temperature in the shed, and then affect the photosynthesis and respiration of plants.
2. At the same time, reflective measures can be taken in the greenhouse to improve the effective utilization of LED grow lights. Use reflective materials when setting up the frame, keep the middle bracket upright, and slightly tilt the north and south brackets, which can increase the light utilization rate. 5- -10%, reused by grows.
Realize the high-efficiency LED grow light to illuminate plants?
LED grow lights are lights used to illuminate planting plants. Plant growers hope that their plants can grow better. The purpose is to give plants growth to achieve the ideal state of light, and efficiently and evenly condense the light on each plant. on. How to achieve high-efficiency LED grow lights to illuminate plants?
1. Distribution of LED grow lights
The uniform distribution of LED grow light beads is to ensure that the light energy is evenly irradiated on the plants. The lamp beads are mainly composed of red and blue lamp beads. If the positions of the lamp beads of different spectrums are not reasonably and evenly distributed, the growth status of the plants in the irradiation area of the LED grow light will be different, and the meaning of using the LED grow light will be lost.
How to control the distribution of lamp beads in LED grow lights? First determine the number of LED grow light beads, and then determine the ratio of red and blue lamp beads according to the needs of planting plants, and then install them on the lamps evenly. If it is a small area to fill light, it can ensure the uniform light in the middle, if it is a large area to fill light, ensure that the surrounding light is even, so that the adjacent LED grow lights can be superimposed, just to achieve the desired effect.
2. The physical reaction of optical equipment
The LED grow light can also realize the efficient use of light under the condition of uniform illumination. The main physical principles used are light reflection and light refraction.
LED grow lights use light reflection and refraction to not only make the light more uniform, but also achieve high luminous efficiency. They mainly use reflectors and metal substrates used in COB. The principle of LED grow lights reflect the light emitted by the light source into a beam of light, increasing the local area. Light intensity, the reflective effect of the metal substrate is also to maximize the light energy emitted by the LED grow light beads to be used by plants, and the reflected part is auxiliary light, which also has the function of fixing the lamp beads and heat dissipation.
The principle of light refraction of LED grow lights is mainly to use optical lenses, the principle of which changes the propagation trajectory of light, generally single lens and retest lens are used, which can control the light distribution very accurately.
The advantages of LED grow lights over traditional plant growth lights are more efficient and even in terms of illumination, and they also have advantages in terms of volume, dimming, and less heat.
Use LED grow lights to better supplement light for plants, full-spectrum or customized red and blue ratios to meet all the spectra of plant growth stages, which can effectively shorten the plant growth cycle.
