(1) Whether the lighting environment is reasonable is one of the important reasons that affect the harvest of vegetables in the greenhouse. Under the irradiation of LED plant lights, plants will undergo photosynthesis, absorb carbon dioxide, exhale oxygen, and accumulate organic matter; in the absence of light, they will perform respiration. It absorbs oxygen, exhales carbon dioxide, and consumes organic matter. When the two balances are equal, the light compensation point of the plant is reached. At this time, the plant cannot accumulate organic matter and grow smoothly. When the light compensation point is not reached, the consumption of organic matter in the plant is greater than the formation of organic matter, and the plant cannot grow normally and appears sick, withered, or even dead. When the plant is thicker than the light compensation point, the plant grows normally. In the absence of sunlight or insufficient sunlight, LED plant lights can be used to supplement light to ensure sufficient light environment, combined with carbon dioxide concentration, moisture, temperature, humidity, etc., to allow plants to perform normal photosynthesis to help their growth.
(2) Choose plant varieties for planting according to market demand. Choosing the right plant varieties is the first step to open the market. Reasonable use of different types of LED plant lights to fill light, and good time to market is an important part of occupying the market.
(3) One thing to pay special attention to is that the air circulation in the shed, especially in order to save costs, using traditional plant lights, will produce some harmful gases, which will have a bad impact on the human body. Some traditional plant lights will produce high temperature when irradiated by them, and the temperature in the shed will be too high, which will cause the loss of vegetable water, which is not conducive to growth; some harmful gases such as ammonia and so on, these harmful gases produced by fertilizers can also be too high. Will adversely affect the growth of vegetables.
Why do plant supplementary lights undergo aging test? Why do plant supplementary lights conduct aging test? Aging test refers to a test process that simulates the various factors involved in the actual process of the product that affect the use of the product, and conducts a test process that strengthens the corresponding conditions. The most common is the aging test for plastics, the main methods are light aging, damp heat aging and hot air aging.
LED plant lights are electronic and electrical products, and their aging test is different from the aging of plastic materials. The most important thing in the use of LED plant lights is to allow them to be used efficiently and normally, and the main factors that affect their normal use are dead lights. Efficiency, heat dissipation, high efficiency and stability of luminescence, etc. The main test methods are all done by increasing the voltage and current.
LED plant light dead-light rate test. Generally speaking, after the LED plant light is produced into a finished product, there is no problem in the studio under the rated voltage and current, but it is inevitable that there will be a short-term high voltage during use, or sudden In the case of power failure, to ensure that the lamp can still work normally after this common situation occurs, it is necessary to do a test before the LED plant lamp leaves the factory to detect whether the power supply configuration is qualified, the welding position is firm, and the assembly wire can withstand a certain level standard.
