The benefits of choosing Yaorong Technology LED plant lights
With the increase of agricultural productivity in China in recent years, greenhouses have developed rapidly. However, due to the low temperature in winter in the north and the short time of sunshine, they cannot meet the needs of crop growth. Although the temperature in the south is higher, there is a lot of rain in winter and spring. Days, there will also be insufficient sunshine, and domestic greenhouses generally need to be supplemented with light. In traditional agricultural production, ordinary electric light sources are generally used to supplement light and apply different covering materials and other agricultural technical measures, such as the use of monochromatic fluorescent lamps or colored plastic films, and changing the light environment to regulate the growth and development of plants in the facility cultivation environment . These measures have different degrees of problems. If the lack of analysis of specific spectral components leads to impure light quality processing, inconsistent light intensity, close to or even lower than the light compensation point of plants, the energy efficiency of the illumination light source is very low. Plant lights can solve these problems, and are especially suitable for artificial light-controlled plant facility cultivation environments.
One,The working principle and use of plant lights
When plants photosynthesize, they need red and blue light instead of green light. The light environment is one of the important physical environmental factors that are indispensable for the growth and development of plants. Th LED plant light source is mainly based on the photosynthesis curve of the plant photosynthesis and the percentage of light absorbed by the photosynthetic pigment to determine the composition and ratio of light quality to provide plants Good light environment. At present, the mainstream plant lights are LED plant lights and fluorescent plant lights.
After application test, the wavelength of led plant light is very suitable for plant growth, flowering and fruiting. Generally, indoor plants and flowers will grow worse and worse with time. The main reason is the lack of sunlight. Illumination by LED lamps suitable for the required spectrum of plants can not only promote their growth, but also prolong the flowering period and improve the flowers. Quality. Mainly can be summarized into three points:
1) As a supplementary light, provide supplementary light for plants in the case of insufficient external light, and maintain sufficient light for plant growth.
2) Extend the light time. For mid-day and long-day plants, natural light cannot provide enough light time. Plant lights can extend the light time to achieve the best photoperiod of plants.
3) Use greenhouses or plant laboratories. Instead of natural light, it can promote the growth of plants.
two,Various performance comparisons
We use professional equipment to measure the luminous flux, luminous efficiency, and red, green, and blue light occupancy data of fluorescent plant lights and Yaorong Technology LED plant lights, and conduct specific comparison analysis. The specific comparison results are as follows.
2.1 Appearance comparison
We can see through the comparison of fluorescent lamp type plant lamp and Yaorong Branch LED type plant lamp that the shape of fluorescent lamp type plant lamp is ring, because only the downward emitted light can effectively illuminate the plant, so its effective light effect And the luminous flux is only about 50%.
2.2 Comparison of luminous flux and luminous efficiency
The luminous efficiency and luminous flux of the fluorescent lamp type plant lamp are slightly higher than that of the LED type plant lamp, but because only the downward emitted light can effectively illuminate the plant, the real luminous effect and luminous flux of the fluorescent lamp type plant lamp are only its own About 50% of it.
Through experiments comparing the luminous efficiency and luminous flux of the fluorescent lamp type plant lamp and the LED type plant lamp, it is obvious that the effect of the LED type plant lamp is better.
2.3 Comparison of the occupancy ratio and relative spectrum of red, green and blue light
It is found that the actual effect of Yaorong Technology’s LED plant light is better than that of the fluorescent plant light. We further compared the red, green and blue light occupancy ratio and spectrum diagram. The sum of the red and blue light required by the plant, the LED plant light occupancy rate is as high as 99.50. %, while the fluorescent lamp type plant lamp only accounts for 53.90%, and the fluorescent lamp type plant lamp also contains 46.10% of the green light Yaorong Technology LED plant lamp which is not needed for plant growth, has a better effect on plant growth.
The wavelengths of fluorescent lamp type plant lamps are very dispersed, so although all kinds of light are available, the occupation ratio is not concentrated, while the wavelength of Yaorong Technology LED plant lamps is very concentrated, and the light emitted is mostly red and blue light. The photosynthesis effect is better. Yaorong Technology LED plant lights can also be equipped with different proportions of color to light occupancy ratios according to different types of plants. Therefore, the effect of Yaorong Technology's LED plant light is better.
2.4 Comparison of other parameters
From the above comparison, it can be seen that the real effect of Yaorong Technology's LED plant lamp on the photosynthesis of plants is far superior to that of the fluorescent lamp plant lamp. The electric power and lifespan of the two kinds of plant lights have obvious advantages and disadvantages
The electrical power of Yaorong Technology’s LED plant lights is only 47.8% of that of fluorescent plant lamps, so it saves more electricity; the lifespan of Yaorong Technology’s LED plant lights is about 20 times that of fluorescent plant lights, which is more durable.
three,Concluding remarks
This article introduces the two mainstream plant lights at present, which are fluorescent-type plant lights and LED-type plant lights. Through the comparison and analysis of their performance with professional measuring instruments, it is found that although the luminous efficiency and luminous flux of the fluorescent lamp type plant lamp are slightly higher than that of the LED type plant lamp, due to the shape of the fluorescent lamp type plant lamp, only the downward emitted light can be effectively irradiated For plants, therefore, the real luminous efficiency and luminous flux of the fluorescent lamp type plant lamp is only about 50% of its own, and the LED plant lamp of Yaorong Technology has a better effect. The sum of the red and blue light occupancy rate of Yaorong Technology's LED plant lamps is as high as 99.5%, while the fluorescent lamp type plant lamps account for only 53.9%, and the fluorescent lamp type plant lamp also contains 46.1% of the green light that is not needed for plant growth. Therefore, Yaorong The high-tech LED plant light has a better effect on plant growth. At the same time, Yaorong Technology LED plant lights have the characteristics of long life, small size and light weight. Yaorong Technology LED plant lights have better effects, are more conducive to the growth of plants, and are suitable for actual production.
