LED plant lamp
LED plant lamp is a special lamp with a specific spectrum wavelength designed to replace sunlight with light emitted by LED light-emitting elements to promote photosynthesis of plants and create a light environment suitable for growth and development of plants. LED plant lights can well control the spectral wavelength and can fully meet the needs of plants for light. The spectral wavelength required for plant photosynthesis is usually in the range of 400 ~ 720nm. The blue light of 400 ~ 520nm and the red light of 610 ~ 720nm contribute the most to the photosynthesis of plants. The red and blue wavelengths of LED plant lights are just in this range, which can provide plants with spectral wavelengths suitable for their growth to promote plant growth. At the same time, LED plant lights also have energy-saving properties (high photoelectric conversion efficiency, power consumption is 1/4 of fluorescent lamps, 1/10 of sodium lamps), spectral tunability, good point light source, luminescence (low heat), good Moisture resistance, small size, long life (more than 30,000 hours), etc.
Plants "walk" from outdoor to indoor.
Studying the growth behavior of plants outdoors not only covers a large area, but also has many uncertain factors, and the research parameters of plant cultivation cannot be fully quantified. Indoors are completely different. What kind of problems does each plant need in different growth periods, what kind of humidity, what kind of light, what kind of light quality already grows best, and under what circumstances What are the different changes? With these quantitative parameters, different plants can be planted in various growth states according to the different needs of human beings. Only plant lights can make plants "walk" from outdoors to indoors. At present, only LED plant lamp can make indoor research reach the highest efficiency.
LED plant lamp installation height
The installation of LED plant lamp must be scientific in order to effectively improve the light utilization rate of plant lights. In order to ensure the light intensity of plants, the plant light should be placed as close as possible to the plant, and the distance should be set according to the power of the plant light. Generally, the closer the distance between the plant lamp and the plant, the higher the light utilization efficiency. Use LED plant lights to fill the light. Since the LED has little heat energy, it will not burn the plants. It can be irradiated at a close distance, and the shortest distance can be 10 cm. Generally, for plant lights with power less than 8W, the irradiation distance is about 0.5 meters, and for plant lights with power greater than 8W, the irradiation distance can be between 0.7-1 meters.
LED plant lamp fill time
Depending on the growth period and growth environment of the plant, the time it takes to supplement light varies. Indoors where the light is not strong but can shine into the astigmatism of the sun, the fill-in time should be no less than 5 hours; the balcony with less than 4 hours of light (only in the morning or the afternoon half day), the fill-in time should be no less than 4 hours ; Shady areas and indoor areas without sunlight should be filled with light for no less than 10 hours. Generally, the time for supplementing light during the growth period of plants is longer and the dormancy period is shorter. On cloudy, rainy, and foggy days, the light should be supplemented for no less than 10 hours. One more thing to note is that since most plants photosynthesize during the day and grow at night, there is generally no need to supplement light at night.
When the growth and development of plants are affected by factors such as weather, seasons, etc., there is insufficient light, and normal photosynthesis cannot be carried out to store organic matter, growth and development cannot proceed normally, and severe conditions may directly wither and die. With the emergence of LED plant lights, plants get rid of the limitation that they can only rely on the sun to grow normally. In addition, it can also increase crop yields, shorten plant growth cycles, and produce high-quality, high-volume, environmentally-friendly crops.
