The plant growth lamp is an application area derived from LED products. The principle of plant growth lamp is to make use of several large bands of plant photosynthesis to make up the light, so that plants can get greater photosynthesis within the same time. Greenhouse plants fill up the lamp. The wavelength of 400-520nm and the wavelength of 610-720nm are particularly important for plant photosynthesis. In order to meet the needs of plant growth, the LED plant fill light is highlighted in two spectral bands of 400-520nm and 610-720nm. The overall lighting is shown as red blue mixed color, which can more effectively fill the light for plant growth.

With the continuous optimization and upgrading of agricultural institutions in China, agricultural development tends to be more modern and intelligent. Among them, the plant growth lamp as a substitute for sunlight to plant growth and development environment of a perpetual lamp, has been the concern of the growers and welcome. It is understood that in 2020, the LED perpetual lamp market will reach 1 billion 400 million yuan, which means that farmers and plant growers including China will use LED plant light. Compared with the traditional plant lamp, led wavelength type is rich, and the spectrum can be adjusted to have more specific nutrition spectrum for plants, which is suitable for different needs of light for different plant growth. It has many advantages, such as high light efficiency, low heat, small volume, long life, etc. it has obvious advantages in aoming light supplement. By adding light to plants by plant growth lights, the occurrence of diseases and pests and malformed fruits can be reduced, the crops can be blooming or fruit early, plant light bulbs will be on the market early, the output of vegetables and fruits will be increased, and the economic benefits of planting operations can be effectively raised.
