Why do the lamp beads of plant lights have two colors?

The Importance of Dual-Color Lamp Beads in Plant Lights

In the field of horticultural lighting, the design of plant lights often incorporates lamp beads that emit two distinct colors, typically red and blue. This dual-color approach is not merely aesthetic; it serves critical functions in promoting plant growth and health. This article explores the reasons behind the use of two colors in lamp beads and their impact on plant development.

The lamp beads of plant lights have two colors, red and blue, because these two colors of light have a specific promoting effect on plant growth. ‌

‌Red lamp beads‌: mainly emit red light, with a wavelength of around 630nm, which can promote plant photosynthesis, germination, flowering and fruiting. Red light helps plant photosynthesis and is one of the key factors in plant growth and development.

‌Blue lamp beads‌: mainly emit blue light, with a wavelength of around 450nm, which can promote plant germination. Blue light is particularly important for the early growth stage of plants, which helps the growth and morphology of plant stems and leaves.

The combination of these two colors of lamp beads simulates the red and blue light components in natural light, which can maximize the growth and development of plants. This combination not only increases the growth rate of plants, but also helps to increase the yield and quality of crops. In addition, the combination of red and blue is visually pink, which is more comfortable for human vision, and can also meet the growth needs of plants, realizing an ideal state of harmonious coexistence between man and nature‌1.

In summary, the plant lamp uses red and blue lamp beads to simulate the red and blue light components in natural light to maximize the photosynthesis and growth and development of plants, while taking into account the visual comfort of the human body, to achieve an efficient, environmentally friendly and humanized lighting solution.
