LED light board blue lightThe main application areas are:
Research and experimentation:
Used for scientific research scenarios such as monochromatic wavelength testing and plant fill lights, supporting precise spectral control
Typical parameters: 300 * 500mm aluminum substrate, equipped with 336 SMD2835 LED beads
Agriculture and Biological Cultivation:
As a light source component for artificial climate chambers/incubators, regulating plant growth cycles
Core mechanism of action:
Photosynthesis regulation:
Blue light (450-470nm) is a key wavelength range for chlorophyll synthesis and photosynthetic pigment absorption in plants, and its intensity is second only to red light for biological use
By regulating photosensitive pigments and cryptochrome, it affects stomatal opening and leaf photosynthetic efficiency
The impact of morphological construction:
Inhibit stem elongation and reduce excessive growth (such as a decrease in stem height of lettuce)
Promote leaf thickening and chloroplast development, increase chlorophyll a/b ratio
Synergistic effect with other light qualities:
Red blue light combination:
Red blue mixed spectrum (such as 7:3 ratio) is more effective in increasing wheat tiller number and lettuce dry matter accumulation than monochromatic light
It should be noted that excessive blue light can inhibit nitrogen assimilation and should be balanced with red light
Full spectrum supplement:
Full spectrum LED light board (including green light) can improve canopy penetration, especially suitable for high-density planting scenarios
The experiment showed that the balance of plant development in the full spectrum group was significantly better than that in the ordinary LED group
Notes:
Dose control:
It is recommended that the proportion of blue light should not exceed 30% of the total light intensity, as excessive use can lead to slow growth
The demand for different varieties varies greatly, such as leafy vegetables requiring a higher proportion of blue light
