LED Lighting in horticulture

Solid-state LED lighting offers a number of benefits to the horticulture industry, including increased yields, earlier flowering, faster root growth/ germination, better control of plant growth, and more economical use of space.

LED lighting is also highly energy-efficient, helping horticultural producers to lower electricity consumption, especially during the high consumption periods of autumn and winter.

Philips Lighting in horticulture

Philips has been developing light sources for horticulture for many years and continues to invest heavily in horticultural lighting. In R&D for Lamps, Lighting Electronics and LED, a team of engineers works full-time to improve existing lamp and gear concepts and to develop new lighting systems for horticultural lighting.

Specialists such as plant physiologists and technical engineers have been trained in the key horticultural countries to provide full support to growers and breeders.

Light and plant growth

Light is essential for plant growth. Natural sunlight is the cheapest source available, but for horticulture it is not always attainable in sufficient quantities. Therefore, the use of artificial light has become very common in order to increase production and quality.

Plants have a completely different sensitivity to light colors than humans.With regard to plant growth, light is defined in terms of small particles, also called photons or quantum. The energy content of photons varies, depending on wavelength (light color spectrum).

For one optical energy, almost one and a half as many red photons can be produced compared with blue. This means that often red light sources produce more efficient light photons than blue light sources.

However the plant has also various sensitivity for various colors of light, and that influences different light-sensitive activities as well. Using the efficient light sources for plants, effective light recipes are important to obtain the optimal results in plant production.

Properties of light

The main properties of light that make the plant grow well/flower are:

Light uniformity:

When using artificial lighting, uniformity and constant quality of the light spectrum is very important for a constant quality of crop production.

Light quantity / intensity:

The growth of a plant is strongly determined by the total number of photons that it absorbs in the PAR region. In winter there is often too little natural light for plants to grow and continue to produce good flowers and fruits.

Day length:

With many plants, the time of flowering is influenced by the photo-period. For example, a chrysanthemum plant will only bloom when the night is long.We call them “short day plants”. However when you apply long day light to them, the flowering will be suppressed.

Spectrum:

The mix of colors in the light (spectrum) also strongly influences the development of a plant.

Application fields

City Farming

(Leafy vegetables and soft fruits)
  • High yields

    With high and stable yields, reduces production costs and continuously stabilizes supply.

  • Sustainable supply

    Shortens delivery time and provides fresh vegetables from a local supply.

  • Multilayer cultivation

    Improves land use rate and increases the yield per unit area by multilayer cultivation.

  • Energy efficiency

    Efficient use of energy can effectively reduce the electrical system load and energy costs and many more applications.

  • More flavour

    Improves quality, nutrient content and flavor.

Vegetables and Fruit

(high wire and  leafy vegetables, herbs and soft fruits)
  • Interlighting

    High wire vegetable production (cucumber and tomato) with interlighting.

  • Complements natural light

    Effectively complements natural light with a spectrum and light intensity combination designed to promote plant growth.

  • Improves plant yield

    Stabilizes and improves plant quality and yield, enabling growers to increase their profits.

  • maximise the light

    The scientifically designed illumination angle and light position allow plants to make maximum use of the light.

  • Energy efficiency

    Efficient use of energy can effectively reduce the electrical system load and energy costs and many more applications.

Benefits of growing with LEDs

Light frequency tuning

Light is an important horticultural production tool and a key factor in plant research. LEDs are set to play a major role in horticultural lighting.

With LED lighting, the growth light – spectral output – can be tuned, which makes it possible to apply the optimum ‘light recipe’ at every stage of a crop’s growth.

Increased yields & early flowering

Together with effective heat management, long lifetime, high luminous efficiency and energy efficiency, LEDs open up tremendous opportunities for growers and breeders.

For the commercial horticulture market this means increased yield, early flowering, faster (root) growth, and more economical use of space.

Increase planting area in limited spaces

In addition, while producing light, LEDs generate less heat, making temperature control in the plant space easier and more economical.

At the same time, LEDs can be installed near plants, to increase planting area in limited spaces.

LED lighting brings new opportunities to horticulture

  • Light spectrum: Provides the best ‘light recipe’ at each growth phase
  • Light intensity: Provides the illumination intensity that crops need
  • Effective heat management: Enables greater control over the climate in the greenhouse or climate chamber and reduces the need for cooling
  • High luminous efficiency: As LEDs produce only a little radiant heat, it is possible to position the light source close to the crop without burning the leaves
  • Long lifetime: Reduces the need to replace lamps
  • Energy efficiency: Lowers energy costs and helps protect the environment
  • Robust: Dustproof and moisture-proof, and no risk of glass in your crops
  • Optical design freedom: Since a LED is only a micro-chip, it fits easily into any application and can increase uniformity
