Abstract

The invention discloses an LED light control device for plant illumination light source light distribution and a control method. The device comprises a power supply module, a control module, a driving module and a light supplementation module, wherein the power supply end of the power supply module is connected with the power end of the control module; the driving power supply end of the power supply module is connected with the power end of the driving module; the driving end of the driving module is connected with the power end of the light supplementation module; the control end of the light supplementation module is connected with the light supplementation control end of the control module; the driving control end of the control module is connected with the control end of the driving module; the driving module comprises a red light driving unit and a blue light driving unit; the red light driving unit drives a red light supplementation module in the light supplementation module; and the blue light driving unit drives a blue light supplementation module in the light supplementation module. The red light driving unit and the blue light driving unit are controlled respectively via the control module, intensity and illumination time of light emitted by the light supplementation module can be adjusted, and growth of the plant is promoted.

Description

technical field [0001] The invention relates to the field of LED circuit control, in particular to an LED lighting control device and control method for light distribution of plant lighting light sources. Background technique [0002] The LED plant lighting light distribution system uses LED (Light Emitting Diode) as the light source. LEDs have been widely used in the field of plant lighting. Compared with traditional light sources, LED has significant advantages such as energy saving, environmental protection, long life, small size, and fixed wavelength. With the improvement of the luminous efficiency of high-power LEDs, the luminous efficacy of power LEDs has nearly reached 100lm / W to 161lm / W, making it possible for LEDs to be used as plant lighting sources. [0003] The application of LED in the field of agriculture is gradually receiving widespread attention from all over the world. At present, LED-based plant lighting technology has made major breakthroughs, and LEDs...

Problems solved by technology

However, most of the research and development programs and products currently on the market still use the method of supplementary light time, supplementary light intensity and light quality constant, without considering the difference in the total light demand of different plants at different growth stages, resulting in insufficient supplementary light or The phenomenon of excessive fill light has not really solved the problem of low energy consumption and precise fill light
