LED light wavelength is very suitable for plant growth, LED light flowering, fruit. LED lamp manufacturers are environmentally friendly, and there are no harmful substances of mercury. The assembly parts of LED bulb can be easily disassembled, and can be recycled by others without recycling by the manufacturer. No strobe. Pure DC operation eliminates the visual fatigue caused by the stroboscopic of traditional light source. Reduce line loss, no pollution to power grid. Power factor ≥ 0.9, harmonic distortion ≤ 20%. EMI meets the global indicators, reducing the power loss of power supply lines and avoiding the high-frequency interference pollution to the power grid.
The LED light bar can save energy significantly. Using super bright high-power LED light source and high efficiency power supply, it can save more than 80% power than traditional incandescent lamp, and the brightness is 10 times of incandescent lamp under the same power. The super long life is more than 50000 hours, which is more than 50 times of the traditional tungsten lamp. Led adopts high reliable advanced packaging technology eutectic welding to fully guarantee the long life of LED. The luminous visual efficiency can be as high as 80lm / W, a variety of LED color temperature optional, high color rendering index, good color rendering. With the passage of time, the flowering status of indoor plants is getting worse and worse, which is mainly due to the lack of light.
Through the spectral LED lamp required by plants, it can not only promote the growth of plants, but also extend the flowering period and improve the quality of flowers. The application of high efficiency light source system in greenhouse, greenhouse and other facilities of agricultural production can also solve the problem of insufficient sunlight in tomato, cucumber and other greenhouse vegetables taste decline. Different wavelengths of light have different effects on plant photosynthesis. Photosynthesis of plants requires light with a wavelength of about 400-700 nm. 400-500 nm (light blue) and 610-720 nm (red) contributed the most to photosynthesis. Blue (470 nm) and red (630 nm) LEDs, which can provide the required plant light, so the ideal choice for LED lights is to use a combination of two colors. In visual effect, the combination of pink, red and blue of plant light.
Blue light promotes the growth of leaves, red LED light is conducive to flowering and fruiting, and prolongs the flowering period. LED lamp manufacturers are environmentally friendly, and there are no harmful substances of mercury. The assembly parts of LED bulb can be easily disassembled, and can be recycled by others without recycling by the manufacturer. No strobe. Pure DC operation eliminates the visual fatigue caused by the stroboscopic of traditional light source. Reduce line loss, no pollution to power grid. Power factor ≥ 0.9, harmonic distortion ≤ 20%. EMI meets the global indicators, reducing the power loss of power supply lines and avoiding the high-frequency interference pollution to the power grid. The red blue ratio of LED lamp is generally 4:19:1, which is the appropriate ratio. Generally, 4 ≤ 7 ≤ 1 is selected. Over the years, in the field of plant artificial light sources, including high-pressure sodium lamp, fluorescent lamp, metal halide lamp, incandescent lamp, etc., the disadvantages of these light sources are high energy consumption, high operation cost, energy cost accounts for about 50% - 60% of the total operation cost. Therefore, improving the luminous efficiency and reducing the energy consumption has become an important topic in the field of plant artificial lighting. According to the statistics of the Ministry of agriculture, the total area of plant tissue culture in China is more than 20000000 square meters, with an output value of 20 million yuan. With the development of modern agriculture, the demand for agricultural lighting is still growing, but the power consumption is significantly increased. With the concept of energy-saving lighting deeply rooted in the people's mind, agricultural market opportunities and the huge energy consumption of traditional agricultural lighting technology have brought new challenges, providing a good opportunity for the development of new agricultural lighting applications.
