Research on Linear LED grow Light - BLE Semiconductor Lighting
There are four forms of light and LED grow light affecting plants: light quality, photoperiod, light intensity, and light quantity. Plant growth and yield (plant size, number of flowers, and other characteristics) are mainly affected by the amount of light received throughout the day. Photosynthesis is mainly affected by the amount of light and light strength. The following is an in-depth study of linear LED grow lights.
Basic knowledge of linear LED grow light
The effect of spectral range
The color temperature and lumens of linear LED grow lights can be seen from the human eye, and the photosynthesis of plants does not look at the color temperature and lumens. Remember to see that the holly seedlings under the purple light are the tallest, but the leaves are small and the roots are shallow, showing a malnourished appearance. According to reports, the red bulb and blue bulb of this light source are configured in a ratio of 9:1. Compared with ordinary plant lights, ordinary plant lights emit ultraviolet light and infrared light that are useless for plant growth, which wastes a lot of electric energy. LED grow lights use an electroluminescence mechanism. Under the same light intensity, LED plants The growth lamp saves more than 80% of electricity than the ordinary plant growth lamp. The lifespan of ordinary plant lights is generally only 1000-5000 hours, while the lifespan of LED grow lights can reach 100,000 hours, long-lasting, energy-saving, high light energy utilization, and does not produce light that is ineffective for plant growth. It is a real promotion of plants.
315 ~ 400nm ——> Less absorption of chlorophyll, affecting photoperiod effect, preventing stem elongation
400 ~ 520nm (blue) —> The absorption ratio of chlorophyll and carotenoids is the largest, which has the greatest impact on photosynthesis
520 ~ 610nm (green)—>The absorption rate of the linear LED grow light is not high
610 ~ 720nm (red)—>The absorption rate of chlorophyll is low, which has a significant impact on photosynthesis and the photoperiod effect
＞1000nm ——> Converted into heat
Based on the above basic knowledge, we can summarize some laws. The linear LED grow light required for plant photosynthesis has a wavelength of about 400 ~ 720nm. 520 ~ 610nm (green) light, the rate of absorption by plant pigments is very low. Linear LED grows lights have many uses and applications in many aspects, but there are also many aspects that we don't know, waiting for us to explore and discover.
Today, the linear LED grow light has been well developed. And the intelligence of linear LED grow lights is very high, and gradually tends to the unification of international standards. Therefore, different vehicles can integrate different linear LED grow lights from different suppliers. Whether it is a linear LED grow light, BLE Shenzhen semiconductor lighting Co., Ltd. linear LED grow light is an ideal choice.
