Multifunctional agricultural LED (light-emitting diode) lighting device

Abstract

The invention belongs to the technical field of agricultural lighting, and particularly discloses a multifunctional agricultural LED (light-emitting diode) lighting device. The multifunctional agricultural LED lighting device comprises an LED light source module, a control module, a high voltage generator, a blue light intensity sensor, a red light intensity sensor, an LED driving module, an external timing and counting device, a power module and a switch module, wherein an red light LED, a blue light LED, an ultraviolet light LED and a white light LED are arranged on the LED power module. According to the multifunctional agricultural LED lighting device, the modules are matched with each other to achieve the effects of light supplementing, pest killing, sterilizing and disinfecting and the like in the growth process of plants. The multifunctional agricultural LED lighting device integrates the functions of light supplementing, pest killing, sterilizing and lighting, thus meeting the requirements on the development of a plant factory.

Description

technical field [0001] The invention belongs to the technical field of agricultural lighting, and in particular relates to a multifunctional LED agricultural lighting device. Background technique [0002] Different plants have different requirements for light during the growth process, and even the same plant has different requirements for light at different growth stages. In some plant factories, in order to meet the light demand for plant growth, people began to use artificial light sources to supplement light for plants, such as the technologies disclosed in my country's patent application numbers 201110050443. LED lighting source. [0003] On the other hand, in order to prevent pesticide residues, light means to kill insects has begun to be applied. For example, a LED insecticidal lamp is disclosed in my country's patent application number 201020202549.6. The LED light sources used are yellow, green, blue, purple, and white. LED, and pests are only most sensitive to the ...

Problems solved by technology

[0003] On the other hand, in order to prevent pesticide residues, light means to kill insects has begun to be applied. For example, a LED insecticidal lamp is disclosed in my country's patent application number 201020202549.6. The LED light sources used are yellow, green, blue, purple, and white. LED, while pests are only most sensitive to the phototaxis of 330-400nm wavelength, and the light utilization efficiency of other colors is relatively low

[0004] To sum up, it can be seen that the LED devices currently used in agricultural lighting have single functions and cannot meet the continuous development needs of plant factories.
