Gardening LED Lighting - Plants and Lighting

Hello everyone, in the first part of plants and lighting, we will discuss how plants see light clearly and how different aspects of lighting formulas can help optimize gardening lighting plans. Welcome to the first webinar on lighting and plant growth. I am KEN, the factory expert of VANQ gardening LED solutions. I work in VANQ and work in the urban agricultural planting center. Our work to promote growth by adjusting light and growth conditions has provided formulas for various crops. In the next 15 to 20 minutes, to effectively grow crops rich in vitamins and flavors, we will discuss the relationship between light and plant growth, and we will pay special attention to the following four topics that must first be paid attention to. What we will explain It is light and how to illuminate plants using light or growth, talk about inefficient lighting systems and the reasons why we use LEDs, and finally we will explain what the light formula is and how the light formula grows. The key component of formula light is that electromagnetic radiation is now only a small part of the visible spectrum, mostly between 380 and 780 nanometers. The light has many defined colors. According to the wavelength, we usually think of light as a particle containing energy, so the so-called photon is the basic particle or quantum of human light.

 

The sensitivity of the human eye to light is different from that of plants. It is particularly sensitive to green clowns and has a broader sensitivity. Photosynthesis is most effective under blue and red light, because we are most effective under blue and red light. Red light is relatively insensitive. We often use locks or cavities to quantify light, but this is not the most appropriate way to measure light and form a scientific vision. We prefer to use weak light to express the number of moles per square meter per second. The wavelength of incident photons is between 4 and 700 nanometers, and is commonly referred to as photosynthetic radiation or plants need light. The photosynthetic sugar formed through this process is used to maintain and grow the photosynthesis of photons. The pigment is stored in the plant. This energy is used to produce sugar from carbon dioxide and water. When oxygen is released, the light contains a lot of information, such as about the time of day, the progress of the season, or the development of the factory. Competitors already have a mechanism to respond to this information. Therefore, light can be used to manipulate plant development, such as morphology. When we want to guide plant development, we can change the light intensity time. We provide the spectrum or direction of light. From the moment of germination, the light throughout the life cycle of the plant will have different effects. From the beginning, the growth of plants determines the growth of plants. The growth direction of these plants is branching and flowering.

 

Certain reactions mediated by a large number of so-called photoreceptors are common. Other plants rely heavily on the plant family, and even usually cause various ultraviolet rays. The defense mechanism plants cause the accumulation of pigments and the accumulation of taste and aroma. Blue light inhibits stretching and stimulates the opening of domino muscles. The green light can enhance this effect. Red light easily penetrates leaves. When the plant is full, it will increase. Stretch the terrace and tend to bloom early. The distance between the relative proportions of red light and far-red light is also an important factor. Vigorous fire promotes the growth and expansion of seedlings to a certain extent. Some examples of how plants respond to monochromatic light often cause developmental delays. In the long run, the death of blonde hair needs some blue light. In addition to emitting red light to grow healthy plants, you can also use light to help color the lettuce on the left. , You will see a head of lettuce. In the Dutch winter version, the blue light in the greenhouse under low illumination will quickly cause red photosynthesis, while the light intensity under high light levels is very high, but with the penetration of carbon, the saturation of carbon dioxide limits the effect of different substances on certain substances. The reaction of these substances. The maximum photosynthetic rate of different plants is very shallow. Elsewhere, carbon dioxide began to limit photosynthesis. Here, you will see a graph where the average light intensity throughout the year is a red Dutch greenhouse, and the light intensity is too high to achieve the best photosynthetic hours per day. , When the light is too dark, it will become obvious immediately.

 

The lighting conditions of LED lights are almost never optimal.. The intensity is too low or too high, which means that growers will want to use auxiliary lighting at certain times of the day, and in other cases, we will have to use shielding screens to maximize growth. We need efficient lighting systems. Efficient lighting first includes lamps with high conversion efficiency. It needs to efficiently convert electrical energy into photons and minimize light loss. We need to provide effective spectrum that will eventually light up Hopalong's life, and require lower service requirements to make the lighting system efficient. The efficiency of the light source largely depends on the spectrum provided, because the energy of photons requires more wavelengths than wavelengths. More energy can produce blue and red photons. The maximum efficiency of blue LEDs is 3.6 micromoles per joule, and the number is the same. Compared with traditional LEDs, power LEDs have many advantages.

 

High-pressure sodium LEDs provide the same amount of light, which is reduced by 40%. Energy-saving lamps do not require any start-up time, they can provide uniform lighting and will not produce infrared radiation, because the spectrum can be adjusted to improve the quality of crops. The spectrum is displayed in the lower panel, and we compare the spectra in the upper left panel. Natural daylight and the two panels at the bottom of the upper right corner show the spectral characteristics of the LED. Blue and dark red, with dark blue, white D bread and far red. When making simple recipes, all recipes start with recipes required in certain plants. The characteristics of plants are very compact, and in other abundant places, early flowering is another major selling point. Higher levels of antioxidants may be an important argument. The price depends on this formula. It is possible to develop lightweight formulas most suitable for crops. In order to achieve the best results, the growth of plants is more than just determining the lighting plan. Determine plant growth, including various other parameters such as nutrient water substrate and grower’s climate. All these factors will always be considered and therefore will always be part of the secret of growth.
