Is dynamic control the next step for LED?

 

What is dynamic control for LED?

Orchid grower Jan has purchased a Hybrid-LED system with 5% blue and 95% red LEDs, with an efficiency of 3.2 micromol/Watt. He provides standard 16 hours of light per day to his crop. In the measurement data, we see that the photosynthesis efficiency decreases after 13 hours. This means that 20% of the energy usage is less efficient. Although Jan has chosen a spectrum with high efficiency of 3,2 micromol/Watt, it is less efficient when considering the light utilization efficiency of the crop.

 

What is light utilization efficiency?

Light utilization efficiency is an important factor to consider when evaluating how efficiently the plant converts photons into growth. This can depend on the crop, the color of the LEDs, and the climate. You can determine this by measuring what is optimal for the crop and what gives the best return on your investment. One way to achieve optimal light usage is through dynamic control by individually dimming the different colors of LEDs in a fixture.

By implementing dynamic control, we observe a direct cost increase of 15-20% per fixture. The dynamic control is programmed based on the specific needs of the crop in your greenhouse. Therefore, it is essential to install the right sensors in your greenhouse. You can then view this information in MyLedgnd.

Does dynamic control of LED lighting provide a good return on investment?

Dynamic control of grow lights has many benefits for both the crop and your wallet.

  • Save energy and extend the lifespan of your LED ligh
  • Maximize the use of natural light with full spectral insight
  • Achieve more consistent crop results
  • Optimize and identify patterns, for example, more blue light in the morning or adjusting the red-to-far-red ratio based on PSS: the phytochrome balance
  • A crop-specific light recipe gives your plants exactly what they need at the right time
  • Quickly adjust to changing weather conditions
  • Learn more about your crops with the help of our experts
 

By programming the lighting based on the data in the greenhouse, we are setting the next level of sustainable lighting in greenhouse horticulture. It provides optimal results with the least energy consumption for lighting. Research shows that dynamic control of LEDs has led to yield increases of 10% and a net energy savings of 30%.
