led grow lights for indoor plants

With the development of artificial intelligence, plant lighting technology and mature, LED lighting source plants because of its small energy consumption, high light efficiency, long service life and can realize low cost according to demand the dimming and customized design, have gradually replaced sodium lamp as the represent the trend of the traditional plant lighting light source, in recent years, development is a hot industry chain; Many domestic and foreign enterprises have also laid out the field of plant lighting, and its application market has gradually become a new direction of LED industry development, such as: landscape lighting, aquarium lights, home or plant factory plant supplement light and total replacement growth lights.

Shenzhen Refond Optoelectronics has always adhered to the principle of leading technology, and constantly committed to the research and development of new hot spots, new technologies and new products. The latest LED plant lighting products can effectively meet the needs of the current plant lighting market. Recently launched a number of LED plant packaging products, including 2835, 3030, covering 450nm, 660nm, 730nm and other plant lighting main bands and full spectrum series or customized spectrum products.

Let's take you to learn about LED plant lighting, Refond plant lighting products and applications.

What is LED plant lighting

Plant growth mechanism:

Plant growth is mainly chlorophyll using light energy, carbon dioxide and water synthesis of organic matter; Light morphology (spectral characteristics, irradiation conditions and intensity, etc.) is used to control stem growth, flower formation, seed germination, etc.

From the spectrogram of plant photosynthesis, it can be seen that photosynthetic pigments (chlorophyll-A, chlorophyll-B, carotene, etc.) of plants have strong photosynthesis at 440-470nm and 620-660nm light waves, especially at 450 and 660nm, there are photosynthetic absorption peaks. At the same time, it was found that 730nm could promote the elongation of stems, increase the length and width of leaves, and control the whole process from germination, vegetative growth to flowering. Therefore, the mainstream band of LED plant lighting is WLP450nm, 660nm, 730nm, and to meet the whole growth cycle of plants, covering plant growth PAR365-780nm, but also covers 365, 410, 530, 590, 620, 640nm and other supplementary band products; However, the spectrum of pure single color light products is narrow and cannot meet the growth needs of plants. It is necessary to match specific spectrum according to the growth cycle and characteristics of various types of plants and meet certain irradiation distribution intensity, commonly known as "light food" for plant growth.

LED plant lighting packaging device products are mainly divided into PAR365-780nm monochromatic light devices, chip plus phosphor color or full spectrum devices, and RGB, RGBWW and other dimming combination devices.

The difference between plant lighting and regular lighting

Conventional lighting mainly focuses on the sensory values of human eyes (color, brightness, etc.), while plant lighting is a combination of plant growth and photosynthesis and humanized environment. In addition to the brightness (lm) and light effect (lm/W) of basic conventional lighting, it also focuses on the needs of plant growth. There are parameters such as band, spectral combination, photosynthetic photon radiation flux and density (PPF, PPFD). Compared with conventional illumination, the important evaluation parameters are photosynthetic quantum quantity PPF(μmol/s) and PPF/W(μmol/s) of luminance per unit time.

Plant lighting industry chain

LED plant lighting industry chain involves artificial intelligence control, plant growth characteristics research, light ratio research, light source device development and plant lighting module development. With its advantages in the field of LED packaging, Refond Optoelectronics continues to layout LED plant lighting packaging, modules, etc., and can provide customized plant lighting technical solutions according to customer requirements.

Refond plant lighting products

On the basis of its rich products, Refond Optoelectronics can provide customized design solutions according to the "personality" requirements of customers' plant lighting fixtures, and realize packaging device solutions with different package sizes, power, wavelength and spectrum requirements, covering the mainstream of the market, such as 2835/3030/3535 package sizes. Related to 0.2W-1W or even higher power type color light, white light, dimming and other plant lighting packaging devices. And the introduction of plant lighting products special test equipment, in order to accurately meet the needs of new product research and development and customer product design, can provide more professional and more accurate plant lighting packaging devices and lighting technology solutions.
