How will we grow food in the future?
OSRAM horticulture lighting takes on the challenges of the 21st century
The world’s population is growing. The available farmland is diminishing. The urbanization is increasing, and with it the transportation distances and expenditures. The ability to provide enough food will become a challenge in the next 30 years. Traditional agriculture will not be able to provide the people in future cities with enough healthy nourishment. We are in need for new and better systems to meet the food supply demand.
Urban farming and indoor vertical farming are good examples of such solutions. We will grow tomatoes, melons, lettuce and the like in the midst of big cities. These plants will need to be fed primarily with water and light. Compared to conventional agricultural solutions, indoor farming achieves significant increases in energy efficiency and can, thus, help vegetable and fruit cultivation in the metropolises of the world to become viable.
OSRAM's main areas of horticulture lighting
We provide lighting systems for vertical farming. By using the right light recipes, it is possible to influence the development of plants, from their growth patterns to their appearance and nutrient content.
We help to explore how light sources influence plant development. Our research luminaires enable tailor-made light recipes for specific plant types. The technologies from OSRAM are used by the NASA, and by growers of medicinal plants.
The plant-Cube makes it easy to grow healthy and tasty lettuce, herbs, and vegetables at home. Dependent on the type of seed inserted the smart box automatically creates the optimal growing conditions.
We deliver systems to commercial growers around the world. Therefore we are combining horticulture lighting ledership with expertise in technologies, sensors and connectivity.
We work with researchers and growers at the forefront of the controlled-environment agricultural revolution to provide products and systems that optimize crop development.
Key to find the best light recipes are self-learning software algorithms that create and optimize digital plant models in order to cultivate tailor-made salads, herbs, vegetables and fruits.
Horticultural lighting solutions, systems and components that we offer already today
Commercial horticulture by Fluence Bioengineering, Inc.
By acquiring Fluence Bioengineering, Inc. in 2018 we took an important step in our quest to become the leading provider of intelligent plant growth solutions. “Fluence is opening the floodgates to a huge future market,” said Stefan Kampmann, CTO of OSRAM Licht AG. “Its extensive knowledge of the horticulture market and possible applications, combined with OSRAM’s expertise in lighting technologies, sensors and connectivity, will position us as a leading horticultural solutions provider.”
LED-based solutions from Fluence help growers meet their yield and sustainability goals by increasing harvests up to 25 percent, reducing energy costs by as much as 50 percent and, through the targeted use of light, improving the quality and nutritional content of plants.More about Fluence - one of the world’s leading suppliers of smart grow lighting [link to Fluence's website]

People want fresh and nutritious vegetables, beautiful floral arrangements, and fragrant herbs all year round, possibly even at the touch of a button with the latest trends in e-commerce. Fortunately, the art and science of growing plants is evolving with new digital and smart technologies for vertical farms, hydroponic greenhouses, and small gardening systems, enabling the optimization of crop development and farms to sprout in big cities and even in people’s homes.
Ongoing light research, sensor technology, and cloud computing allow horticulture professionals to meet the increasing demands of today’s consumers, and provide everything from LED grow lights to complete solutions.More information on OSRAM's horticulture lighting applications More about PHYTOFY RL, our horticultural lighting system used by the NASA
Study: The financial impact of vertical farming
What if all of New York’s annual lettuce consumption was produced in local vertical farms? - OSRAM developed a special application study for New York and examined four different technology scenarios regarding lettuce production. The calculation of the environmental and socio-economic impacts of the four scenarios was done together with KPMG using established monetization approaches.
The result is clear: Compared with open-field farming, vertical smart LED farms make the biggest positive contribution to society: A total of €322 million could be saved, if all citizens of New York City consumed lettuce produced in LED vertical farms. Annually!More about the financial and also social advantages of vertical farming over open-field farming
How does light affect plant growth?
- Light quantity
The amount of light affects the photosynthesis process in the plant. This process is a photochemical reaction within the chloroplasts of the plant cells in which CO2 is converted into carbohydrate under the influence of the light energy.
- Light quality regarding spectral composition of the light
The spectral composition of the different wavelength regions (blue, green, yellow, red, far red or invisible e.g. UV or IR) is important for the grows, shape, development and flowering (photomorphogenesis) of the plant. For the photosynthesis, the blue and red regions are most important.
- Light duration
The timing / light duration which is also called photoperiod is mainly affecting the flowering of the plants. The flowering time can be influenced by controlling the photoperiod.
Every plant has its own light requirements, therefore plant-specific ‘light recipes’ are being researched extensively. By using the right light, it is possible to influence the development of plants, from their growth patterns to their appearance and nutrient content.
What is horticulture lighting?
Horticulture lighting is used to support, increase and enable the growth of plants by illuminating them with artificial light. LED Light is a very efficient way and upcoming solution for this application! Horticulture lighting is used -
- as supplemental lighting: To supplement natural daylight and raise grow light levels in order to enhance photosynthesis and thereby improve growth and quality of plants in greenhouses
- as photoperiodic lighting: To control the light period by extending the natural day length with artificial light
- for cultivation without daylight: To totally replace daylight with artificial light for ultimate climate control
What are the optimum wavelengths?
Horticulture lighting is focusing on LEDs with mainly 450nm, 660nm and 730nm wavelength.
- The 450nm and the 660nm are providing the energy for the plant to life and grow. The amount of light is not measured in lumen but in amount of photons. The common unit in horticulture lighting is µmol/s in the range of 400-700 (photosynthetically active region).
- The 730nm is necessary to control the growth of the plant.
