What is the difference between Plant Grow Lamps and Normal LED Lights ?
Difference A: the wavelength of the emission spectrum is different. The plant growth lamp is mainly composed of the red and blue components in the visible spectrum, the ordinary light is only the light emitting diode, and the spectrum is concentrated in the green part.
Difference B: different purposes. Normal lamps can replace spiral incandescent lamps or power-saving bulbs. There are 5 to 40 Watt low-power incandescent lamps, and plant lamps can enable plants to produce the best photosynthesis, obtain the best growth state, and promote the differentiation of multiple lateral branches and buds during plant growth.
1、 What is the difference between plant lamp and normal lamp?
1. Different emission spectrum wavelengths:
The plant growth lamp is mainly composed of red and blue components in visible spectrum. Ordinary lamps are only light-emitting diodes, and the spectrum is concentrated in the green part.
LEDs used in the field of plant culture also show the following characteristics: rich wavelength types, just consistent with the spectral range of plant photosynthesis and light morphogenesis; The half width of spectral wave is narrow, and pure monochromatic light and composite spectrum can be combined as required,; It can focus light of specific wavelength to irradiate crops evenly; It can not only regulate the flowering and Fruiting of crops.
It can also control plant height and plant nutrients; The system has less heat and small occupied space, and can be used in multi-layer cultivation three-dimensional combination system to realize low heat load and miniaturization of production space; In addition, its strong durability also reduces the operation cost.
2. External difference
LED is also called light emitting diode. The core part is a chip 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.
According to the luminous intensity and working current, it can be divided into ordinary brightness (luminous intensity < 10mcd), high brightness (luminous intensity 10 ~ 100mcd) and ultra-high brightness (luminous intensity > 100mcd). Its structure is mainly divided into four parts: the structure of light distribution system, the structure of heat dissipation system, driving circuit and mechanical / protective structure.
Research on LED as supplementary lighting for plant photosynthesis traditional artificial light sources produce too much heat. For example, with LED supplementary lighting and hydroponic system, the air can be recycled, and too much heat and water can be removed.
Electric energy can be efficiently transformed into effective photosynthetic radiation and finally into plant matter. The results show that the growth rate and photosynthetic rate of lettuce are increased by more than 20% by using LED lighting. It is feasible to use led in plant factory.
3. Different uses
LED lamps can replace spiral incandescent lamps or energy-saving bulbs, from 5-40 watts, low-power incandescent lamps to 60 watts (only about 7 watts).
Led plant lamp helps to shorten the growth cycle of plants, because the light source of this lamp is mainly composed of red and blue light sources, and the most sensitive light band of plants is adopted. The red light wavelength is 620-630nm and 640-660nm, and the blue light wavelength is 450-460nm and 460-470nm.
These light sources enable plants to produce the best photosynthesis and obtain the best growth state. Experiments and practical applications show that in addition to supplementing light for plants during the lack of light, they also enable plants to promote the differentiation of multiple lateral branches and buds, accelerate the growth of rhizomes and leaves, and accelerate the synthesis of carbohydrates and vitamins, Shorten the growth cycle.
