Research on Heat sink of Led Plant Growth Lamp

LED plant growth light is an artificial light source that uses LED (Light Emitting Diode) as the illuminant to 

meet the lighting conditions required for plant photosynthesis. According to the type, it belongs to the 

third generation of plant fill light! Usually, it is composed of LED PCB light source module plus power supply ,

fan and this high power Skived fin heat sink.

Light environment is one of the important physical environmental factors that are indispensable for plant growth 

and development. Controlling plant morphology through light quality regulation is an important technology in the

 field of facility cultivation; plant growth lights are more environmentally friendly and energy-saving. LED grow lights

 give plants Provide photosynthesis, promote plant growth, shorten the time for plants to bloom and fruit, and

 improve production! In modern construction, it is an indispensable product for crops, and its light attenuation is 

also an important issue. Among them, the selection of heat sinks And unreasonable design will lead to serious light 

attenuation.

There are many types of LED wavelengths, which are exactly in line with the spectral range of plant photosynthesis

 and photomorphology; the half-width of the spectral wave is narrow, and pure monochromatic light and composite 

spectrum can be obtained by combining as needed; it can concentrate light of a specific wavelength to irradiate

 crops evenly; not only It can adjust the flowering and fruiting of crops, and can also control the plant height and 

the nutrients of plants; if a high-power Skived fin heat sink is used, the heat dissipation area is large, the system 

heat is less, and the space is small. Low heat load and miniaturization of production space.

As the fourth-generation new lighting source, LED has many characteristics different from other electric light sources,

 which also makes it the first choice for energy-saving and environmentally friendly light sources. LEDs used in the field 

of plant cultivation also exhibit the following characteristics: rich in wavelength types, which just coincide with the 

spectral range of plant photosynthesis and photomorphogenesis; measuring the photosynthetic luminous flux density

 (PPFD) spectral width of plant growth lamps produced by plants is narrow at half width, which can be Combining pure

 monochromatic light and compound spectrum as needed, it can concentrate specific wavelengths of light to irradiate 

crops in a balanced manner; it can not only adjust crop flowering and fruiting, but also control plant height and plant

 nutrients; the system generates less heat and takes up space Small, it can be used in multi-layer cultivation

 three-dimensional combination system, realizing low heat load and miniaturization of production space; in addition,

 its strong durability also reduces operating costs. Due to these remarkable features, LEDs are very suitable for plant 

cultivation in controlled facility environments, such as plant tissue culture, facility horticulture and factory seedling 

raising, and aerospace ecological life protection systems.

LED grow lights can help 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 bands for plants, red light wavelengths use 620-630nm and

 640-660nm, blue light wavelengths use 450-460nm and 460-470nm. Measure the wavelength of the plant growth lights.

 These light sources allow plants to produce the best photosynthesis, and the plants get the best growth state. 

Experiments and practical applications have shown that, in addition to providing supplementary light for plants during 

the lack of light, it also allows plants to obtain the best growth conditions. In the process of growth, plants promote the 

differentiation of multiple lateral branches and buds, accelerate the growth of roots, stems and leaves, accelerate the 

synthesis of plant carbohydrates and vitamin synthesis, and shorten the growth cycle.

With the rapid increase in global demand for organic food, vigorously developing organic planting is an opportunity 

for more and more producers. At the same time, considering energy issues and the greenhouse effect, appropriate

 lighting structures and heat dissipation solutions should be selected. Winshare Thermal can provide customers 

with A complete set of designs.
