Full-spectrum grow lights are lighting sources for plant growth developed by simulating the solar spectrum. The ratio of visible light in the spectrum from 380NM to 780NM red light is reasonable, and the light wave color spectrum simulates the solar spectrum, and the shape of the light is like daylight at about 10 o'clock in the morning. Color, strong color rendering, small color temperature difference, high luminous efficiency and large luminous flux.
Shenzhen AMERI has successfully introduced full-spectrum grow lights into the market and created a professional grow lights brand-AGLEX. In practical applications, AGLEX full-spectrum grow lights can fully meet the requirements of greenhouse plants to supplement light.
It is not difficult to see from the spectrogram that the incandescent lamps used by growers for a long time have uneven distribution of the spectrum, but the spectrum is relatively comprehensive. Under the condition of reaching the illuminance, it still has a certain effect on the growth of plants, but the light efficiency is too low and energy High consumption and short service life. Sodium lamps, energy-saving lamps, large curve changes, uneven spectral distribution, LED plant lights have certain advantages in the ratio of red and blue, but the spectrum is incomparable with sunlight, and the cost is high. The light color is purple and the brightness is low. Full-spectrum plants The lamp, whose spectral distribution simulates the solar spectrum, is an ideal supplementary light source for agricultural greenhouses, agricultural research institutes, agricultural ecological gardens, and landscape plants in large-scale offices.
The role of light compensation points:
The light compensation point is the illuminance value when the photosynthetic intensity and respiration intensity of the plant are equal.
Above the light compensation point, photosynthesis of plants exceeds respiration and can accumulate organic matter. Below the light compensation point, the respiration of plants exceeds photosynthesis. At this time, instead of accumulating organic matter, the stored organic matter is consumed.
If the plant is below the light compensation point for a long time, the plant will gradually wither and cause death. When the temperature rises, the respiration effect increases, and the light compensation point rises.
Therefore, when cultivating plants in a greenhouse, the temperature should be avoided when the light is insufficient, so as to reduce the light compensation point and facilitate the accumulation of organic matter.
The light compensation point of the plant group is also higher than that of a single leaf. Because there are many leaves in the group, they shade each other. When the light intensity is weak, the upper leaves can still perform photosynthesis, but the lower leaves have strong respiration and weak photosynthesis, so the whole group The light compensation point rises.
