Agricultural lighting system

Abstract

The invention relates to an agricultural lighting system. The agricultural lighting system comprises a power supply module, an optical environment control module, a spectrum acquisition module, an LEDplant growth lamp, an optical radiation illuminometer, a combined spectrum database and a processor. The power supply module provides power for the system; and the processor is connected with the optical environment control module, the spectrum acquisition module, the LED plant growth lamp, the optical radiation illuminometer and the combined spectrum database separately. According to the agricultural lighting system, spectrum of output light of the LED plant growth lamp and light radiation illuminance of the light receiving surface of a plant are monitored in real time by a spectrometer andthe light radiation illuminometer, and real-time monitoring data of the light environment are fed back to system software; and meanwhile, the adopted power supply system can further avoid the situation that the lighting system cannot work due to failure of power supply or circuit.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an agricultural lighting system. Background technique [0002] Based on the development needs of modern agriculture and the goal of promoting my country's transformation from a large agricultural country to a powerful agricultural country, the modernization of agricultural lighting is one of the main contents of agricultural modernization. [0003] In the field of agricultural lighting, compared with traditional light sources, the advantages of LED light sources are more prominent: using the characteristics of adjustable and controllable LEDs, concentrated effective wavelength irradiation makes bio-energy efficient. LED is a cold light source that can be irradiated at close range, which can greatly increase the plant cultivation density. The energy saving effect produced by the application of LED agricultural lighting is remarkable. From the characteristics of the LED lig...
