Research and application of LED plant grow light spectrum
In the past, plants only grew according to the season, but now under LED grow light, plants can change the growth cycle. Why? The study of light begins with the spectrum
The research basis of light is spectrum. The application quality of light needs spectral analysis. The spectrum of LED plant light is particularly important. The manufacturer’s design ability of grow lights spectrum determines its market competitive position. The spectrum of LED plant grow lights needs to be specially designed according to the planting process and cannot be imitated.
Plant factory technology is divided into planting equipment technology and planting process technology. Plant grow lights spectrum technology is an important correlation point between planting equipment and planting process. It needs to be clear that planting process determines spectrum design. The design and manufacture of LED plant lamp is to ensure that the light quality required by planting process can achieve the best efficiency, These characteristics of led grow lights determine the complexity and diversity of plant spectral design.
Spectral applications are divided into visual applications and non visual applications. Lighting belongs to visual applications and plant lighting belongs to non visual applications,
The usual theory of plant photosynthesis is to study the wavelength range of 400nm-700nm, and the sunlight spectrum plays an important reference role in the spectrum design of indoor plant grow lights, but it is not dependent. Trying to imitate the sunlight spectrum to plant growth light is a futile and inefficient practice.
Because the spectrum of LED grow light source can be designed according to the requirements of planting technology. At the same time, the spectrum of LED grow light source can realize the control of variable spectrum through dimming technology. LED grow light source is the only led plant lamp light source that can realize variable spectrum at present. The technology of variable spectrum of indoor plant lamp is mainly aimed at light form control and has little effect on energy saving, Ordinary plant lamps can also save energy through the adjustment of photoperiod, and the application cost of variable spectrum will increase a lot.
After the spectral form of the led grow light is determined, the highest YPF or PPF corresponding to this spectral form can be calculated, which is very important for evaluating the application of LED plant grow lights and the main method for comparing the performance of LED plant grow lights with other types of grow lights,
The spectral design of LED plant growth lamp is the equipment support ability required by the planting process, which is related to the market competitiveness of the plant lamp manufacturer. It is the main feature to measure the manufacturer’s technology and process. The spectral design of plant grow light led reflects the manufacturer’s selection of LED chip and package, the spectral analysis and calculation ability of grow light led , the light distribution design of grow lamp, and the control of light quantum subfield uniformity, The comprehensive manufacturing level of driving technology, heat dissipation technology, product reliability control and installation structure design indicates the technical strength of the manufacturer’s products in the market. Applying the above aspects to evaluate plant lamp products can reduce investment risk and procurement risk
