Full-automatic illumination device for plants

Abstract

The invention discloses a full-automatic illumination device for plants. The device comprises more than one irradiation units, a controllable constant-current power supply, a water pump, a sensor group, a display circuit, a key control circuit and a microcomputer circuit, wherein each irradiation unit comprises a light-emitting diode (LED) light source circuit board, an aluminum substrate and a plurality of LED light sources. The LED light sources are welded on the LED light source circuit board, the LED light source circuit board is connected to the controllable constant-current power supplywhich is controlled by the microcomputer circuit, and the light intensity of the LED light sources is automatically regulated by the microcomputer circuit. For the full-automatic illumination device for the plants, the number of the irradiation units can be selected according to an irradiation area, and more than two irradiation units are connected by electrical appliances and used in a combined mode. Different illumination modes can be selected by the device according to different plant types, and the light intensity and the irradiation methods of the LED light sources can be automatically regulated by the microcomputer circuit according to an ambient temperature, light intensity and humidity, so that plant growth is promoted optimally. The device performs full-automatic control, has a good heat radiating effect, and can be widely applied to plant growth irradiation.

Description

technical field [0001] The invention relates to the fields of electronic technology and biotechnology, in particular to a fully automatic control plant lighting device. Background technique [0002] In agricultural production, the application of artificial light sources has a long history. With the rapid development of LED technology, the preparation technology of high-power LEDs has become increasingly mature. It is of great economic value to use LEDs as light sources for plant lighting. However, my country's application of LEDs to agriculture is in its infancy. Studies have shown that blue and red LEDs can promote plant growth, adjusting the combination of blue and red LEDs, and adding a certain proportion of ultraviolet light on the basis of the optimal combination of blue and red light is more conducive to the growth of plants. grow. At present, this research is in its infancy, and there are the following problems: (1) The existing plant lighting devices cannot be full...

AI Technical Summary

Problems solved by technology

At present, this research is in its infancy, and there are the following problems: (1) The existing plant lighting devices cannot be fully automatic dimming

Different plant growth cycles and different external environments have an impact on the lighting conditions of plants. Existing devices cannot automatically adjust according to these factors, and cannot optimally promote plant growth; (2) Existing plant lighting devices cannot be widely used under different plant lighting

Different plants have different requirements for the intensity of light of different wavelengths, and fixed light intensity cannot be used for different types of plant illumination; (3) The existing plant devices do not solve the heat dissipation problem well
