A device for intelligently controlling LED plant growth lighting

Abstract

The invention provides a device for intelligently controlling illumination of an LED plant growth lamp. The device for intelligently controlling illumination of the LED plant growth lamp comprises a control host, an LED light source module and a heat dissipation module, wherein the control host is used for controlling irradiation intensity; the LED light source module is used for driving an LED drive circuit and performing illumination according to a command; the heat dissipation module is used for conducting heat dissipation on the LED light source module; the control host controls the drive circuit and the LED light source module through a communication bus, adjusts irradiation intensity of the LED light source module according to a preset user command, and drives the LED light source module through the drive circuit. By means of the device for intelligently controlling LED illumination for plant growth, the LED irradiation intensity and the light quality ratio can be adjusted, the photoperiod can be set, and the most suitable light rays can be used for illuminating the plant so as to promote growth of the plant.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to a device for intelligently controlling LED plant growth lighting. Background technique [0002] Light environment is one of the essential environmental factors in plant growth and development. Light regulates plant growth and development by affecting plant photosynthesis, light quality composition and photoperiod. Relevant research data show that blue light with a wavelength range of 400-510nm in visible light has the largest absorption ratio of chlorophyll and carotenoids, and red light with a wavelength range of 610-720nm has a low absorption of chlorophyll, which has a significant impact on photosynthesis and photoperiod effects. The light of 315-400nm will cause less chlorophyll absorption of plants, affect the photoperiod effect, and prevent stem elongation. Therefore, under different light sources, the growth status of plants will be very different. There are four types of light effec...

AI Technical Summary

Problems solved by technology

[0004] 1. Low light efficiency, low bioenergy efficiency, poor controllability and high energy consumption;

[0005] 2. The light quality is fixed, and the ratio of red and blue light cannot be adjusted as needed to meet the specific requirements of different plants for light quality at each stage of growth;

[0006] 3. Traditional light sources all have heating characteristics, which will cause burns to plants when irradiated at close range, thereby affecting plant cultivation density; 4. Traditional light source lamps have poor uniformity, which may easily lead to poor consistency of plant growth;

[0007] 5. Plant supplementary light lamps with traditional light sources or ordinary LED plant growth lights require users to have high knowledge in agricultural plant supplementary light technology, which is not conducive to the application of products

[0008] 6. The lighting mode of LED plant growth lights in the market is fixed, which cannot simulate the light cycle and mode of natural light, and cannot achieve a good energy-saving effect
