What is the difference between plant growth lights and ordinary LED lights? Aug 31 , 2021

Plant growth is inseparable from a light source and needs photosynthesis. However, for many indoor cultivations, there is no sunlight and the sunlight is unstable. There is basically no light source in continuous rainy days, which is not conducive to plant growth and plant growth. The lamp was born under this situation, so what is the difference between the plant growth lamp and the ordinary LED lamp?

 1. The wavelength of the luminescence spectrum is different:

  Plant growth lamps are mainly red and blue components in the visible light spectrum. Ordinary lamps are just light-emitting diodes, and the spectrum is concentrated in the green part.

  The LED used in the field of plant cultivation also exhibits the following characteristics: rich wavelength types, just in line with the spectral range of plant photosynthesis and light morphology; spectral wave width half-width narrow, can be combined according to needs to obtain pure monochromatic light and composite spectrum, and can be concentrated The light of a specific wavelength irradiates the crops in a balanced manner; it can not only regulate the flowering and fruiting of the crops.

  It can also control the plant height and the nutrient composition of the plant; the system generates less heat and occupies a small space, and can be used in a multi-layer cultivation three-dimensional combination system to achieve low heat load and miniaturization of production space; in addition, its exceptional durability is also reduced Operating costs.

 2, different shapes

  LED is also called light-emitting diode. The core part is a wafer composed of P-type semiconductor and N-type semiconductor. There is a transition layer between P-type semiconductor and N-type semiconductor, which is called P-N junction. When the current flows from the LED anode to the cathode, the semiconductor crystal will emit light of different colors from purple to red. The intensity of the light is related to the current.

  3, different uses

  LED lamps can replace spiral-type hot-lamps or energy-saving bulbs, ranging from 5-40 watts, low-power thermal lamps, to 60 watts (only about 7 watts of electricity are required).

  LED plant lights help shorten the growth cycle of plants, because the light source of this kind of 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 wavelengths use 450-460nm and 460-470nm.

  Plant growth lights can 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 of plants.
