Features of LED plant lights:

1. Different wavelengths of light have different effects on plant photosynthesis. The wavelength of light required for plant photosynthesis is approximately between 400-700 nanometers. Among them, 400-500 nanometers (blue) and 610-720 nanometers (red) contribute the most to photosynthesis.

2. Blue (470 nanometers) and red (630 nanometers) LED lights can provide specific wavelengths required for plant growth, so the combination of these two colors is considered to be an ideal choice. In terms of visual effects, the red and blue combination of plant lights presents a unique pink color.

3. Blue light helps promote the growth of green leaves, protein synthesis and fruit formation; while red light can promote the growth of plant roots and stems, help flowering and fruiting and prolong the flowering period, thereby increasing yields.

4. The red and blue LED ratio of LED plant lights is generally between 4:1 and 9:1, and a ratio of 6-9:1 can usually be selected.

5. When using plant lights to supplement the light for plants, the lamp is generally placed at a height of about 0.5-1 meters from the leaves. Continuous irradiation for 12-16 hours a day can completely replace sunlight.

6. The effect of using LED plant lights is very significant. The growth rate of plants is nearly 3 times faster than under natural conditions.

7. It solves the problem of lack of sunlight in greenhouses in winter, promotes the synthesis of chlorophyll, anthocyanin and carotene required for plant photosynthesis, enables fruits and vegetables to be harvested 20% earlier, increases the yield by 30% to 50%, and increases the sweetness of fruits and vegetables and reduces the occurrence of diseases and pests.

8. LED light sources, also known as semiconductor light sources, have a narrow wavelength and can emit light of a specific wavelength, so the color of light can be precisely controlled.

By irradiating plants individually, plant varieties can be improved.

9. LED plant growth lights have low power but high efficiency because they emit specific red and blue light in the full spectrum, while other traditional lamps emit full-spectrum light containing seven colors, and most of the light energy is wasted.

Therefore, the efficiency of traditional lamps is much lower than that of LED plant growth lamps. In addition, since the spectrum of traditional sodium lamps lacks blue light, and the spectrum of mercury lamps and energy-saving lamps lacks red light, the supplementary lighting effect of these traditional lamps is not as good as that of LED lamps. In contrast, the use of LED plant lights can save at least 90% of electricity and greatly reduce operating costs.

Comparison of several light spectra:

- Advantages of LED plant lights:

1. No driver or cooling fan is required, and it can be directly plugged into a standard power socket connector.

2. Plants need an environment with red and blue wavelengths when growing.

3. Compared with other ordinary lighting equipment, LED plant lights have gentle light and will not burn seedlings.

4. Compared with other plant lighting lamps, LED plant lights can save 10% to 20% of electricity bills.

5. Blue light can promote plant growth, while red light makes plants bloom and bear fruit.

The role of full-spectrum plant growth lamps: Full-spectrum plant growth lamps are an artificial light source with a full spectrum developed according to the growth law of plants and simulate the solar spectrum ratio. It has a wide radiation range, reaching more than 100 lumens per watt, which truly meets the requirements of green lighting. For agricultural greenhouses as supplementary lighting, it can enhance the light intensity at any time of the day to help plants always photosynthesize. Especially in the winter months, the effective lighting time can be extended. Whether it is dusk or night, it can effectively extend and scientifically control the light required by plants, without being affected by any environmental changes. In a greenhouse or plant laboratory, it can completely replace natural light and promote plant growth.

For indoor plants and flowers, the growth may become worse and worse over time, mainly due to the lack of sufficient light. If it is irradiated with a spectrum suitable for the plant, it can not only promote its growth, but also prolong the flowering period and improve the quality of flowers and trees. Because this light source has a strong color rendering, the flowers and trees are brightly colored under full-spectrum light, giving people a pleasing feeling.

Features of full-spectrum plant growth lamps: Full-spectrum plant growth lamps are developed based on the wavelength range of sunlight and the required illumination required for plant growth. Their reasonable use can not only breed and grow under conditions that are not suitable for plant growth, but also speed up the breeding of crops and shorten the growth cycle of crops, avoiding the occurrence of pests and diseases and deformed fruits. Full-spectrum plant lamps are artificial light sources with a full spectrum, and the resulting beams are most suitable for plant growth (including chlorophyll, anthocyanins and carotene). The floodlight effect of special floodlights makes the irradiated light effect evenly distributed, and the light effect is twice that of sodium lamps with the same wattage and seven times that of incandescent lamps.

Full-spectrum plant growth light source distribution:

- When each set uses 35 watts, the optimal irradiation radius is 4-5 meters, the optimal installation height is 2-2.5 meters, and the interval is 4-5 meters.

- When each set uses 70 watts, the optimal irradiation radius is 5-6 meters, the optimal installation height is 2.5-3 meters, and the interval is 5-6 meters.

- When each set uses 150 watts, the optimal irradiation radius is 10 meters, the optimal installation height is 5-7 meters, and the interval is 10-12 meters.

- When each set uses 250 watts, the optimal irradiation radius is 15-20 meters, the optimal installation height is 8-12 meters, and the interval is 15-20 meters.

Controlling plant morphology through light quality regulation is an important technology in the field of facility cultivation.

Full spectrum plant lights contain wavelengths of 400-420 nanometers, which help form anthocyanins and inhibit excessive elongation of branches and leaves; wavelengths of 450-460 nanometers can thicken stems and leaves and accelerate plant development; wavelengths of 550 nanometers promote oxygen growth and help tissues accumulate nutrients better; wavelengths of 580 nanometers promote root and early germination growth; and wavelengths of 650-660 nanometers are particularly suitable for the growth of plants as a whole, especially during the flowering and fruiting periods, it can increase growth rate (flowering 20 days earlier, harvesting 30 days earlier), increase the number of fruits by 25%-35%, and reduce the incidence of deformed fruits. As for the light absorption rate of 720-1000 nanometers, which is lower, it is mainly used to stimulate cell extension and affect the process of flowering and seed germination.
