LED Plants Growth Lights

Wednesday 03rd February 2021 Back to list

LED plant growth lamp is an artificial light source that uses LED (light emitting diode) as the luminous body to meet the lighting conditions required for plant photosynthesis. In an environment lacking sunlight, plant growth lights can act as sunlight, allowing plants to grow and develop normally or better, have strong roots, promote growth, regulate flowering and flower color, promote fruit maturity, color, and improve taste and quality!

Light is one of the important physical environmental factors indispensable for plant growth and development. Controlling plant morphology through light quality regulation is an important technology in the field of cultivation. Plant growth lights are more environmentally friendly and energy-saving. LED plant lights provide photosynthesis to plants, promote plant growth, shorten the time it takes for plants to bloom and bear fruit, and increase production. In modernization, it is an indispensable product for crops.

Led plant growth lights have the following characteristics:

1. There are many types of wavelengths, which coincide with the spectral range of plant photosynthesis.

2. The pure monochromatic light and compound spectrum can be obtained according to the required combination.

3. It can concentrate light of specific wavelength to irradiate crops evenly.

4. It can regulate the flowering and fruiting of plants, and also control plant height and plant nutrients.

5. The plant growth lamp generates less heat and occupies a small space. It can be used in a multi-layer cultivation three-dimensional combination system to achieve low heat load and miniaturization of production space.

LED plant growth light helps shorten the growth cycle of plants, because the light source of this light is mainly composed of red and blue light sources, using the most sensitive light band of plants, red light wavelengths use 620-630nm and 640-660nm, blue light The wavelengths used are 450-460nm and 460-470nm. These light sources are used to make plants produce the best photosynthesis, and the plants get the best growth state. Experiments and practical applications have shown that in addition to supplementing the light during the lack of light, they also promote the growth of plants during the growth process. The differentiation of side branches and buds accelerates the growth of roots, stems and leaves, accelerates the synthesis of plant carbohydrates and vitamins, and shortens the growth cycle.

In traditional agricultural production, ordinary electric light sources are generally used to supplement the light and the application of different covering materials and other agricultural technical measures, such as the use of monochromatic fluorescent lamps or colored plastic films, and changing the light environment to regulate the growth and development of plants in the facility cultivation environment. However, these measures have problems of varying degrees, such as lack of analysis of specific spectral components, resulting in impure light quality processing, inconsistent light intensity, close to or even lower than the light compensation point of plants, and low energy efficiency of the illumination light source. A large number of research results on the application of LEDs in plant facility cultivation environments show that LEDs can solve these problems and are particularly suitable for artificial light-controlled plant facility cultivation environments.

Using plant growth lights, farmers who grow vegetables in greenhouses can arbitrarily set or prolong the photosynthesis of the plants according to their own time, especially on rainy and hazy days, the plants can also grow normally. Similarly, people can also apply plant growth lights to plant factories and flower gardens.
