What You Should Know Before Using Led Light In Greenhouse

Why is LED light supplement more energy efficient?

As a cold light source light, LED light can convert electrical energy directly into light energy without excessive heat generation during the process, so energy consumption is less. At the same time, high-pressure sodium lamps and red and blue LED supplementary lights are used to supplement the top of the plant canopy. Both can achieve the same output, but the LED only needs to consume 75% of the energy.

What is the scope of LED supplement light?

It can improve the quality of pepper, tomato and eggplant seedlings and improve the quality of grape fruit. Make the cucumber color more vivid. LED supplemental light can improve the quality of the fruit. Among them, the blue light supplementation treatment has the fastest fruit development, the fruit's single-grain quality is higher, and the sugar content is the highest. The ultraviolet supplemental light treatment has the largest single-grain quality at the fruit maturity stage.

How does LED supplement light affect plant growth?

The ideal choice for LED fill light is to use a combination of blue and red.

• Different wavelengths of light have different effects on plant photosynthesis. The light required for photosynthesis of plants has a wavelength of about 400-700nm. 400~500nm (blue) light and 610~720nm (red) light contribute the most to photosynthesis.

• The blue and red LED fill lights can just provide the light needed for plant growth. Therefore, the ideal choice for LED fill lights is to use a combination of these two colors. In terms of visual effects, the red and blue combination of the fill light is pink; blue light can promote the growth of green leaves, and red light helps to blossom and fruit and prolong the flowering period. The ratio of red to blue of LED fill light is generally between 4:1 and 9:1, usually 4 to 7:1.


Why is the price of LED supplement light relatively high?

Longer service life, high safety, no harmful elements, more environmentally friendly. LED fill light has been continuously upgraded and developed. As a fourth-generation new semiconductor light source, LED adopts DC drive, with a service life of more than 50,000 hours and low attenuation. As a cold light source, it can be close to plants. In contrast, LED fill light is safer, does not contain harmful elements, and is more environmentally friendly.
