Pay attention to various issues before and after purchasing LED grow lights
LED grow light aging test
LED grow 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 grow lights is to allow them to be used efficiently and normally, and the main factors that affect their normal use are the rate of dead lights. , Heat dissipation, high efficiency and stability of luminescence, etc. The main test methods are all done by increasing the voltage and current.
LED grow light luminescence test
The main influencing factor is the rectification and voltage division capability of the internal power supply. As long as the power supply is of high quality, the LED grow light can guarantee high efficiency and normal light within its rated service life, and the general power supply will be equipped with an over-voltage automatic power-off device, LED grow The lamp chip has the possibility of leaks during the packaging process, so a flashing test must be carried out to ensure stable, normal and efficient operation.
LED grow light heat dissipation test
The heat dissipation performance of the LED grow light is directly related to its service life and the luminous efficiency of the lamp beads. If you want to see its heat dissipation performance, try an experiment to increase the temperature to an equilibrium state in a certain space for a period of time, and its internal structure will not be destroyed, and at a certain level Within time, the temperature of each part of the LED grow light will not increase with the prolonged high-intensity working time.
LED grow light dead light rate test
After the finished LED grow light is produced, there is no problem with the light in normal operation, but a short period of high voltage may be encountered during the work process, or the light may be suddenly cut off. Make sure that this common situation occurs. The lamp can still work normally. It needs to be tested before the LED grow lamp leaves the factory to detect whether the power supply configuration is qualified, the welding position is firm, and the assembly wire bearing capacity reaches a certain standard.
Before buying LED grow lights
One is that the spectrum of LED grow lights can be modulated in a certain proportion according to plant growth requirements.
The second is that the LED grow light is a cold light source that can be irradiated close to the plant. After continuous practice, the distance is determined to be 30 to 50 cm, which can ensure the light intensity and the illuminated area at the same time.
The third is strong controllability, which can precisely control the light intensity, light quality and light cycle, which is suitable for factory-based production.
The fourth is energy saving, environmental protection, long life, small size and light weight.
Fifth, there are various installations (light boards, light strips, light tubes and bulbs), which are suitable for all kinds of facility agricultural projects.
After-sales attention of LED grow lights
Pay attention to the power of LED grow lights. Power will affect the light intensity. Under certain conditions, the light intensity affects the progress of photosynthesis. Then it depends on the characteristics of the plants. If plants are more light-loving, choose high-power to meet the light demand, otherwise choose normal power.
Pay attention to the fill light time when filling light. Different plants have different requirements for lighting time. This is the same as the above power. Seeing the characteristics of the plants, plants that are more light-loving must take a longer time to fill the light. Otherwise, normal fill light is fine, and the plants also need to rest, pay attention to staying Set a certain amount of time for the plants to rest.
Pay attention to safety issues. The blue light of LED grow lights is the same as other electronic products, which is harmful to human eyes. This aspect needs to be paid attention to, so you need to wear anti-blue goggles to protect your eyes.
The harm of blue light:
1. Blue light will aggravate the disease in the macular area of the retina;
2. Blue light can cause damage to the fundus after cataract surgery;
3. Blue light can cause blurred vision and cause visual fatigue;
4. Blue light can cause glare;
5. Blue light can inhibit the secretion of melatonin and disturb sleep.
No matter what we buy, we always want to buy something suitable for ourselves, so we must understand before and after the purchase. The same is true for purchasing LED grow lights. The understanding of the product will at least make you not lose or choose a more satisfactory one. product.
