LEDs are a fourth generation new type of illumination source, which has many advantages over the past generation of illumination products, such as energy saving, safety, long life, high light efficiency, etc. Due to its revolutionary innovation, the global illumination market of LEDs at the present stage is getting more and more popular to consumers, and especially under the global greenhouse effect and energy-tight large environment, LEDs stabilize the core position of illumination series products.

It is well known that in nature, various plants must rely on sunlight to provide energy to grow more flourishing. According to the biological theory, the illumination is helpful for accelerating chlorophyll in the plants to absorb various nutrients such as water, carbon dioxide and the like, and more carbohydrates are synthesized to further promote the growth of the plants. In conclusion, light exposure is an important physical factor essential for any plant growing from germination to maturity. The plant lamp is produced because the plant lamp can simulate the sun illumination, and the core of the plant lamp is that the plant lamp can be artificially regulated and controlled, the growth speed of the plant can be pertinently increased or the form construction of the plant can be controlled by adjusting the illumination state of the plant lamp, so that the plant lamp is an important technology in the field of modern plant cultivation.

Scientists have summarized the effect of different wavelengths of light on plants by studying their core principles in photosynthesis. The influence of 280-315 nm on the form and physiological process is extremely small; chlorophyll with the wavelength of 315-400 nm (purple) has little absorption, influences the photoperiod effect and prevents the stem from extending; the chlorophyll and the carotenoid with the absorption ratio of 400-520 nm (blue) is the largest, and the influence on photosynthesis is the largest; the absorptivity of the 520-610 nm (green) pigment is not high; the absorption rate of chlorophyll of 610-720 nm (red) is low, and the chlorophyll has obvious influence on photosynthesis and photoperiod effect; the absorption rate of 720-1000 nm is low, cells are stimulated to be prolonged, and flowering and seed germination are influenced. However, in the conventional agriculture, because the backward farming technique and the lack of related equipment, a great deal of labor is spent in farming, and the labor cost is greatly increased. In the 21 st century where this high-tech development was rapid, labor had to be liberated from traditional agriculture and replaced with more "intelligent" agricultural equipment.

Therefore, with the help of modern science and technology, design a can remote control, intelligent control's semi-automatization LED plant lamp, all have historical meaning to the reform of traditional agricultural technology and innovation.
