LED plant growth lamp

Abstract

The invention provides an LED plant growth lamp which comprises a lamp panel, an LED lamp and a control device. The LED lamp is mounted on the lamp panel and is electrically connected with the control device; a power source, a control circuit, a keyboard and a display device are arranged in the control device, and the control circuit comprises a switch, a single chip microcomputer, a real-time clock circuit, a detection circuit, an optical isolation dimmer, a regulating circuit and a communication circuit; and the power source, the keyboard, the display device, the real-time clock circuit, the detection circuit, the optical isolation dimmer, the regulating circuit and the communication circuit are electrically connected to the single chip microcomputer. The LED plant growth lamp has the advantages that the single chip microcomputer measurement and control technology is adopted, so that the light intensity, the light quality and the light cycle of an LED light source are adjustable, and requirements of growth periods of different plants are met; and illumination, temperature and humidity detection, control and regulating links are set for the LED plant growth lamp, devices such as an air-conditioner, a fan and a humidifier can be automatically started/stopped to provide suitable environments for growth of the plants, and accordingly the LED plant growth lamp is high in intelligence level and has a good practical function.

Description

technical field [0001] The invention relates to a plant growth lamp, in particular to an intelligent LED plant growth lamp. Background technique [0002] my country has gradually applied LED lights to the field of modern agricultural production in the first ten years of the 21st century. Because it has low energy consumption, long life, and can adjust the light quality and quantity according to the needs of crops, it can promote crop production and development, and significantly improve Therefore, it is receiving more and more attention from people. [0003] There are records that different wavelengths of light have different effects on plant photosynthesis. The light needed for plant photosynthesis has a wavelength between 380 and 780 nanometers; while blue-violet light with a wavelength between 380 and 520 nanometers and a wavelength of 610 nanometers Red-orange light between ~780 nm contributes the most to photosynthesis. [0004] Blue LEDs typically emit blue light with...
