The introduction of the modulating control could not be more timely. Many growers are struggling with the high energy prices, which are often forcing them to not use their light installations or to restrict their use. It is impossible to predict how long the overly strained situation will go on. What is clear is that every opportunity to save energy and make installations work more efficiently should be used. Large-scale replacement of HPS lights with LEDs is one example of this.
“LED installations use significantly less power per micromole of PAR light supplied, but the final efficiency also depends on how you use them,” says Kevin de Kok, Priva consultant. "Modulating control offers the greatest flexibility to make optimal use of the lighting installation. A dimmable LED installation is a requirement for this.”
Modulation and dimming
Modulation involves adapting different light sources (solar and LED) to meet the light demand. With separate software, LED lighting can already be dimmed. Connext 914 allows lamps to modulate based on the light the crop is already getting from the sun. The software uses data from the PAR sensor or Solarimeter for this purpose. By dimming LED light, the available amount of light is distributed evenly throughout the greenhouse. That is a big advantage over turning off some of the HPS lamps.
“Such broad functionality is unique," adds Marcel Beekenkamp, Technical Consultant. “But we didn’t stop there. The modulating control is fully integrated into Connext 914’s light and screen control. With this expansion, fixed spectrum LED fixtures and far-red light from almost all common manufacturers can be controlled. Because of the integration in Connext, we can also connect it relatively easily to the company-wide electricity management. This, in turn, opens up new perspectives in cost savings and the optimal use of the available installations.”
