How is the development status and trend of plant lighting?

In the field of plant lighting, as one of the fastest growing agricultural lighting fields in recent years, LED has obvious advantages in plant lighting because of its high luminous efficiency, low heat generation, small size and long life. With the maturity of technology, companies have moved from the general lighting market to the field of plant lighting. Plant lighting has broad prospects.

Then, in the process of development, what are the current problems of LED plant lighting? What is the proportion of LED in plant lighting? How is the future development trend of LED plant lighting compared with other light sources in plant lighting?

At present, the plant lighting lamps used in greenhouses are mainly high-pressure sodium lamps in the world. Domestically, they are mainly fluorescent lamps. LED lamps are practically few. In recent years, the growth rate of applications in the cannabis field has accelerated. Some plant factories also use LEDs. However, in general, LEDs currently account for a small percentage.

The first biggest feature is that the vegetables grown in the plant factory are very safe. Only in a controlled environment, it is illuminated with LED lights, and its environment and nutrient solution are controlled by humans. This is beyond the green vegetables, and there is no need to use any pesticides or herbicides in the plant, and our nutrient solution avoids the contamination of heavy metals in traditional soils. The second feature, because we are artificially created shortcuts, the air is filtered, the water is purified, and the dust and bacteria are very low. The third characteristic is that the products of the plant factory are very fresh. Compared with the losses caused by long-distance transportation of other traditional agricultural plants, the plant factory is placed around the big city. It can be completed within 12 hours from the receipt of the table, and the effect of planting vegetables at the door of the house is the same.

In addition, compared with traditional agriculture, plant lighting factories can be customized. Traditional agriculture is limited by the fact that climate and temperature change all year round. Although greenhouse greenhouses can now eat anti-season products, plant factories have no concept of season. The products are the same throughout the year and are highly efficient.
