LED Plant Lighting for an Ideal Growth

LED Pflanzenbeleuchtung Tomate

A large choice of fresh fruits and vegetables in winter? Lush house plants in dark rooms? For many of our demands concerning plants the sunlight in our latitudes is not enough. The solution: An ideal LED Plant Lighting adds the missing sunlight through artificial lighting to reach an adequate growth.

However, to grow, plants need a specific lighting: They can perform photosynthesis in the so-called PAR spectrum. This spectrum is wider than the spectrum of light visible for humans; especially the red and blue components are important. This is why greenhouses often use a mixture of red and blue light. The disadvantage is that humans cannot properly work in such a purple light to, for example, examine the quality of plants. Experts continue to quote that the rest of the PAR spectrum is also important for plants.

Here, the advantages of a LED Plant Lighting come into play. While fluorescent lamps have a set spectrum, the combination of various LEDs can create a white light in which plants can grow properly and humans can work effectively. The light can even be adjusted to specific types of plants. By using sensors it is possible to tailor the additional light to the sunlight in order to dim the artificial lighting on sunny days and, thus, save costs. It is also possible to increase or decrease plant growth on demand through a light control. Due to their high service life LEDs are also practically maintenance-free.

An LED Plant Lighting can, thus, help to improve the life cycle assessment of fruits and vegetables because they can be planted locally and do not need to be transported thousands of kilometres into supermarkets. A combination of plants and general lighting is also useful in other areas. Plants do not only look good in a lobby, but also improve the climate and decrease the sound level.

Increase the vitamin C content of plants with an ideal LED Plant Lighting

Tomatoes often do not get enough sunlight in greenhouses. This leads to poor growth and, thus, a large part of the harvest needs to be sorted out. If you shine artificial LED light on tomatoes, additionally to natural daylight, the growth improves and the vitamin c content of these tomatoes doubles.

Interesting facts: Photosynthetically active radiation (PAR):

Electromagnetic radiation (EMR) (380-780 nm) is mostly used by plants for photosynthesis. This EMR area (380-780 nm) mostly coincides with the area of radiation visible for humans (380-780 nm), which represents approximately 50 percent of the global radiation. PAR is being absorbed by chlorophyll and pigments, which absorb in the red and blue spectral range; green, however, is being reflected. PAR is mostly quoted from 400-700 nm in W/m².

Since PAR controls the primary production and, thus, the carbon fixation of terrestrial and marine vegetation, it influences the energy and water exchange (evapotranspiration) between the vegetation and the atmosphere. In climate research, the photosynthetic active radiation is an important factor for the calculation of the carbon accounting of terrestrial and marine vegetation.
