Description

A LED plant growth promotion system

technical field

The invention relates to the technical field of lighting fixtures, in particular to an LED plant growth promoting system.

Background technique

The growth of plants requires light, and light plays a key role in the growth process of plants. However, the time for plants to grow by relying on sunlight is limited after all, and the radiant energy of sunlight is obviously affected by weather changes, so it cannot be adjusted according to people's wishes. Prolonging the photosynthesis time of plants, let alone achieve 24-hour uninterrupted lighting. For example, in the northern region, due to the short light time in winter and cloudy, rainy, snowy, foggy and other weather, the crops will be seriously short of light, while the southern plants Lack of light will also occur in continuous rainy and plum rainy climates, which will cause crops to fail to perform photosynthesis.

On the other hand, the relatively large amount of light that the sun shines on the earth has a wavelength range of 350nm to 750nm, but not all light in the wavelength range can be used by plants. The organ of plants for photosynthesis is chloroplast, which captures light energy by its own main pigment - chlorophyll, and performs photosynthesis; chlorophyll mainly includes chlorophyll a and chlorophyll b, and its absorption spectrum has two peak areas, namely 400-480nm The blue-violet light region and the red-orange light region of 600-680nm. Therefore, in order to achieve the optimization of plant growth, it is required that the plant lighting source must have the luminescence spectrum of the above two peak regions at the same time.
