What Is Full Spectrum Plant Light?

full spectrum plant light

A full spectrum plant light is a kind of lighting source which is beneficial to the growth of plants and is developed to simulate the solar spectrum. Full-spectrum means covering all the components of the visible light band of the sun, namely red, orange, yellow, green, blue, indigo violet, corresponding to the wavelength range of 380nm-780nm. Plant light, also known as plant growth lights and plant fill lights, are different but different. The most vegetable lamps in the market are high-pressure sodium lamps and LED lamps. However, LED lamps are the main direction of development, with many advantages. The appearance of a plant light is mainly to supplement the light for plant growth.

Sunlight and full spectrum plant light

A full-spectrum plant light is a kind of lamp that provides a light source for plant growth and development according to the natural law of plant growth and the principle that plants use sunlight for photosynthesis. Even with the development of technology, there is still a big gap between the function and efficiency of full-spectrum plant light and sunlight, but with further research, the gap is getting smaller and smaller, and the full spectrum plant light we produced can better promote the growth of plants.

The structure of sunlight

We all know that the sunlight is white, but in fact, the “white light” contains seven kinds of color light – red, orange, yellow, green, blue, indigo, and purple. Therefore, the meaning of “imitating the sun” and “full-spectrum” is that the light of the plant light and the sunlight are the same, But we human eyes certainly can’t see the seven colors of light directly.

Prism – using the refraction principle of light, we can see the seven colors of light after passing the sunlight through the prism. Some time ago, a friend bought a plant fill light, and then took it home to test with a prism. Finally, he concluded that the full spectrum plant fill light is fake.

Why does my friend say that? The light refracted by the plant fill lamp through the prism is not seven colors, so it is concluded that the plant light is deceptive.

First of all, I admire my friend for his clear thinking and flexible use of what I learned in middle school. I can think of measuring the light composition of plant light through the prism refraction principle in middle school; Secondly, I would like to correct the error in the understanding of full-spectrum plant fill lamp by ordinary people and plant lighting industry (or friends who are good at plant planting).

The structure of spectroscopic light

In the plant lighting industry, whether it is to open online stores or to make export trade or offline wholesale, the “full spectrum plant fill light” refers to the visible light band, from blue to red light band of various components are included, here we should pay attention to, is “included” (LED plant to fill light energy is concentrated in red and blue band). The spectral components of sunlight, visible light of each band component are very sufficient, attention is “sufficient”.

See the figure below

From the as like as two peas, the plant lights are almost the same as those of the sun’s light. But in the industry, the plant light that covers all visible bands is called the “all-optical spectrum plant light”. Let’s go back to the above matter of using a prism for the light scattering test. Because the “full spectrum plant light” contains all the bands of visible light, after scattering out, it will generally go out seven color bar facula, but some monochromatic light components are more, high intensity, easy to observe, some components are less, low intensity, difficult to observe.

As like two peas, what is the reason why these plants do not make the light of plant light the same as the sun? This is going back to what is a plant light? The topic of what to do?

Although other visible light can also affect plant growth, the blue band and the red band have the most significant effect on plant growth. Therefore, in the research and development of plant light, to improve the utilization of energy, highlight the blue band and red band of light components. The light components of plant light with a red-blue ratio are completely red and blue bands. However, with the improvement of LED chip technology, the technology of LED intelligent lamp beads is mature. In the same lamp, there are lamp beads that produce different bands of light. Through chip control, we can produce the full spectrum we want. This kind of full-spectrum technology is very popular and has been introduced into the market in a large number. Now many factories use full-spectrum plant lamps.

Therefore, to sum up, as “plant light” and “small white”, we should correctly understand the conceptual difference between full-spectrum and solar spectrum of plant fill lamp and its practical significance in the application.

What is a light compensation point

Light compensation point is the light value when the energy consumed by plant respiration and the energy produced by plant photosynthesis is at the same level

At the light supplement point, when the light intensity decreases, the photosynthesis will also decrease, the respiration will exceed the photosynthesis, and the organic matter consumed by plants is more than the organic matter produced. Above the light compensation point, photosynthesis exceeds respiration, and plants produce more organic matter than they consume. Organic matter accumulation.

If it is lower than the light compensation point for a long time, the plant will consume the accumulated organic matter for a long time. After the stored organic matter is completely consumed, the plant will wither or even die. When the temperature is low, the plant activity is low, the photosynthesis is slow, and the compensation point is low. When the temperature is high, the plant will experience high cell activity, fast photosynthesis, and high compensation point. The compensation point is directly related to the temperature. Therefore, to reduce the plant activity, promote the accumulation of organic matter and reduce the light compensation point, temperature control is very necessary, especially when the light is not enough.

There are many leaves of plants in the colony sheltering each other, and it is difficult for the leaves below to get enough light. All the leaves below have weak photosynthesis and strong respiration. Moreover, the more the colony, the more the leaves below, the more the leaves under respiration, so the light compensation point of the whole colony will rise. However, there is no occlusion problem in monocotyledons, the leaves can get enough light and photosynthesis is strong, so the light compensation point is decreased.

The role of the full spectrum plant grow light

All-optical growth plants produce light that simulates the ratio of the solar spectrum, which corresponds to the principle of plant growth. The full spectrum artificial light source developed by moonlight has high power and a wide range, which really meets the requirements of green energy-saving lighting.

For greenhouse planting, light is controllable, and supplementary light can be enhanced at any time in 24 hours, which can help plants carry out photosynthesis for a long time, accumulate organic matter rapidly and grow rapidly. In winter, the lack of sunlight, greenhouse plants can not grow normally, this time light compensation is the very necessary, effective, and scientific design of light compensation time and intensity, can make up for the lack of sunlight, let crops grow fast without environmental impact. Greenhouse experiments show that full spectrum plant light can replace sunlight and promote plant growth.

After the application test, the light generated by moonlight full spectrum plant light has a very high degree of fit with the light required for plant growth, which can effectively promote the growth, flowering, and fruiting of plants. Under normal circumstances, indoor plants will grow worse and worse in the absence of light and even wither and die. If the appropriate spectral illumination can be added, the growth of plants will not be affected. If the spectrum is scientifically modulated, the flowering period can be prolonged and the quality of plants can be improved

The office halls or conference halls of large enterprises are usually decorated with flowers and plants. Due to the lack of light, it is difficult to keep the activity of flowers and plants for a long time. Moonlight full-spectrum lighting lamps can perfectly solve this problem. Moonlight lighting has a beautiful appearance. The light source can provide the light for photosynthesis for plants, and under the full light, the flowers, plants, and trees are colorful and pleasing to the eye.

The characteristics of the full spectrum plant grow lamp light are

MOKOLight full spectrum plant grow light is an all-optical plant grow light based on the wavelength range of sunlight required by plant growth and the illumination needed. The rational use of this light can make plants grow and develop under the condition of insufficient or no light. If it is regulated scientifically, it can speed up crop breeding, shorten the time required for flowering and fruiting, and improve the quality of crops.

  1. The full spectrum plant light produces a complete spectrum of the light source, and there is always light needed by plants. The light beam produced by the full spectrum plant light is suitable for common plants and can be used for photosynthesis with chlorophyll, anthocyanin, and carotene of plants.
  2. The professional floodlight, which can produce the floodlight effect with uniform distribution of light efficiency, is 7 times the incandescent lamp with the same power and 2 times the sodium lamp.

The distribution of all light sources for plant grow light

35W for each set: the interval is 4-5m, the best irradiation radius is 4-5m, and the best installation height is 2-2.5m.

70W for each set: the interval is 5-6m, the best irradiation radius is 5-6m, and the best installation height is 2.5-3M.

150W for each set: the interval is 10-12m, the best irradiation radius is 10m, and the best installation height is 5-7m.

250W for each set: the interval is 15-20m, the best irradiation radius is 15-20m, and the best installation height is 8-12m.

The principle of the full spectrum plant grow light:

A light environment is one of the important physical environmental factors for plant growth and development. It is an important technology in the field of protected cultivation to control plant morphogenesis through light quality regulation.
