How to Detect the Advantages and Disadvantages of LED Plant

2021-08-05

Photosynthetic Photon Flux Density (PPFD), photoperiod and spectral distribution are of great importance to plant photosynthesis in plant cultivation. Therefore, in the process of plant cultivation, using LED to provide lighting, it is necessary to test the light quality and PFD by spectral elf-plant lighting, and then adjust the light source. It can not only effectively cultivate plant growth and morphogenesis, shorten the cultivation cycle, improve the quality, but also reduce a lot of energy consumption and reduce. Cost.
 
 
 
Photon quantum flux density (PPFD) refers to the light flux density in photosynthetic active radiation (PAR), which represents the number of photons incident in the wavelength range of 400-700 nm per unit area of time. PPFD is a key factor in detecting LED plant growth lamps.
 
 
Because PPFD is calculated from known spectra, not directly related to plant light response. In order to confirm the validity of illumination to plants, the effective spectral value of PAR must be weighted to obtain the effective photon flux density (YPFD), which will vary with the change of the reference PAR effective spectrum.
 
 
 
Lighting passport can provide you with necessary measurement information in the LED plant lighting industry
 
 
 
1. Effective Quantum Absorption Spectroscopy: Inspect the amount of light absorbed by plants, and more efficiently adjust the appropriate light to help plants grow healthily.
 
 
 
2. Photon quantum flux density of PPFD: Measure photosynthetic effective light or radiation energy to understand plant growth light source environment.
 
 
 
1. Built-in PAR reference spectra: built-in photosynthesis absorption spectra, chlorophyll alpha, chlorophyll beta, carotene alpha. Comparing the spectral differences of the current examinations
 
 
 
2. Analytical data: 2-1 Analysis of plant data differences at daily measurement points, labeled values and values. In YPFD section, different PARs can be switched to compare the data differences of different plant growth lamps by 2-2 analysis of absorbed light intensity.
 
 
 
3. Rapid comparison: Comparing the differences of two plant growth lamps 3-1 can observe the differences of original spectum and weighted spectum under Normalized mode 3-2 Compare PPFD, YPFD, Efficiency, R/B, R/FR, CCT, CRI (Ra), Illumination, Lambda p, etc. Lambda D
