Heliospectra case study

The impact of dynamic lights on photosynthesis

Dr. Shizue Matsubara at the Forschungszentrum Jülich in Germany is using Heliospectra’s adjustable LED lighting system which allows you to program rapid and dynamic fluctuations in light intensity. The programmable LED lights are being used to study how these changes in light intensity can affect the process of plant performance and photosynthesis. Dr. Matsubara’s goal with her study is to understand what changes are made throughout different lighting environments. Below are a few key findings and observations made from using the LED lights.



LED lights expand research opportunities
Prior to using Heliospectra’s intelligent LED lights, Dr. Matsubara felt that her research was limited due to the types of lights that were available for research. When using Heliospectra lights, you have the ability to program the light intensity which can be changed frequently over the course of a day or even weeks. This dynamic lighting condition represents a natural light environment that helps with plant growth. Researchers are able to see how the photosynthetic apparatus develops and adjust its properties.

Wavelength specifications
Dr. Matsubara is currently using seven different wavelengths through Heliospectra LED lights. Matsubara explains in her research that there are many wavelengths in natural light, it’s very limiting to only be able to use one. Having the capability to determine what the plant’s response would be under a specific wavelength it’s crucial for quality research. Heliospectra lights allow you to select certain wavelengths and manipulate the intensity.

Less energy, more research
Heliospectra lights do not generate much heat compared to other strong lighting sources. This enables you to adequately study the effect of light intensity on plants separate from the effects of heat. If heat is generated by the lights, you are unable to control the temperature if the leaves heat up. While using Heliospectra LED lights, Dr. Matsubara found she didn’t have to be concerned with raising the temperature of the plants. Halogen lamps, for example, emit far more heat than photosynthetically active lights.
