Traditional artificial lighting is mainly carried out by incandescent lamps, halogen lamps and high-pressure sodium lamps. These traditional light sources have the disadvantages of single emission wavelength and high energy consumption. As a new type of artificial lighting, Yaorong 1000w LED plant light has more advantages and advantages compared with traditional plant light.
Yaorong 1000w LED plant light can adjust the spectrum to form the best environment for plant growth; increase the spatial cultivation density, suitable for multi-layer cultivation three-dimensional combination system; the heat generated is small, and the plants can be irradiated at close range without being burned .
Analysis on the design elements of Yaorong 1000w LED plant light
Spectral distribution
Different light sources have different spectral energy distribution peaks, and their effects on plants are correspondingly different. The wavelength range required for plant growth and development is 400-700 nanometers, of which red light (600-700 nanometers) and blue light (400-500 nanometers) are the main wavelengths of photosynthesis. Since the quantum efficiency of red light is higher than that of blue light, the proportion of red light is higher than that of blue light in the application of Yaorong 1000w LED plant light.
Ultraviolet light with a wavelength of less than 400nm and far-red light with a wavelength of 730nm, although not directly driving photosynthesis, can be used as environmental signals to affect plant growth and metabolism.
Effective lighting techniques
1. Install evenly distributed
Measure the floor area. Multiply the length by the width to get the square meters of the planting area. You can make the right choice based on how much power to provide per square meter, that is, how many Yaorong 1000w LED plant lights are installed per square meter. In this way, each lamp can be evenly distributed, so that the outer edge will receive strong light, so that the light will be more uniform, and the growth of plants will be more effective.
2. Illumination distance
The illumination distance of the Yaorong 1000w LED plant light is very important. You need to adjust the points for different plants at different stages, and you must also unify the distance to make the light even more uniform. If the distance is not well controlled, it may damage the plants. Grow. The general recommendation is that the germination stage distance: 60 cm, the seedling stage distance: 75 cm, the growth stage distance: 45 cm, and the flowering stage distance: 30 cm.
3. Lighting time
The lighting time of Yaorong 1000w LED plant light is mainly determined by plants, and it is divided into two types, positive plants and negative plants. Positive plants are more light-loving, and the lighting time can be longer when supplementing the light, usually 18/6 (on/off) or 20/4 (on/off). For negative plants, the lighting time is normal, usually 12/12 (on/off).
4. Dimming level
The dimming of Yaorong 1000w LED plant light can make plants grow better at each stage, the general germination rate: 30%; seedlings: 50%-75%; growth: 75%-100%; flowering: 100%. Give plants the best growth status.
5. Humidity, temperature
Photosynthesis and transpiration rate are directly affected by temperature, humidity and airflow. Find the best temperature and humidity for your plants between 75*-85*F and 50%-70% humidity, and have sufficient airflow to replenish carbon dioxide.

Yaorong 1000w LED plant light intensity
Light intensity mainly affects the photosynthesis rate of plants, which in turn changes the morphology of plants. Plants’ demand for light intensity is usually expressed by light compensation points and light saturation points. When the light intensity light saturation point, the transpiration speed increases. Plants close their stomata to prevent excessive water loss, trigger oxidative stress and cause greater damage to photosynthesis.
Light intensity not only affects the photosynthesis rate of plants, but also affects the quality of fruits. Low light conditions can adversely affect plants.
Yaorong 1000wLED Plant Light Cycle
Photoperiod is an important signal source for regulating plant growth and development. The flowering time of plants is closely related to the season. Winter jasmine blooms in early spring, while chrysanthemum does not bloom until autumn. This is related to the fact that plants adjust themselves by experiencing periodic changes in light time. The growth cycle is related. It has a profound effect on plant seed germination, plant flowering time and plant dormancy. Photoperiod affects the elongation of plant stems and the level of internal growth hormone, and induces the expression of genes that promote vegetative growth. By appropriately extending the photoperiod.
Photoperiod is also an important factor in inducing plant dormancy. Strawberries grow longer due to the short sunshine time, while woody plants such as poplars and mulberries will dormant due to the reduced sunshine time.
Yaorong 1000w LED plant light quality
Light quality specifically refers to the corresponding spectral distribution of light received by plants. It also has an important influence on plant photosynthesis and morphogenesis.
Most of the solar spectrum is in the range of 300-2600 nm, and the visible spectrum is 380-720 nm. Light with a wavelength of 400-700 nm can be used for photosynthesis by plants and become photosynthetic effective radiation. For ultraviolet light with a wavelength of less than 400 nanometers and infrared light with a wavelength of 700 to 800 nanometers, although they cannot directly drive photosynthesis, they can be used as environmental signals to affect plant growth and metabolism.
Red light can greatly promote the growth of cotyledons and the elongation of apical hooks, and can increase the growth rate of leaves, but simple red light irradiation will limit the expansion of leaves. By supplementing red light, the plant height of tomato and yellow light seedlings can be significantly increased.
Blue light mainly affects the growth and development of plant rhizomes. The number of roots of crop seedlings under blue light irradiation, blue light can increase the root vigor and absorption area of seedlings. Blue light has an inhibitory effect on the elongation of the stem. Compared with white light, blue light significantly reduces plant height, but can increase stem thickness.
Yaorong 1000w LED plant light can not only emit monochromatic light with a narrow light wave, but also can match the light quality according to the needs of plants, which not only gives plants better growth, but also has a promising market prospect.
