Lamp capable of promoting plant growth and method for promoting plant growth utilizing lamp

Abstract

The invention discloses a lamp capable of promoting plant growth. The lamp capable of promoting the plant growth comprises a lamp body which is provided with a man-machine interaction interface, a light source, a light modulator, a light sensor, a power supply unit and a controller, and the man-machine interaction interface is used for setting illumination parameters needed by a plant; the light source comprises red light LED particles and blue light LED particles, the light modulator is connected with the light source and used for setting and adjusting output power for red light and blue light, the light sensor is used for sensing light intensity in the outside world| and transferring a sensing signal to the controller, the power supply unit comprises a first power supply and a second power supply and is used for providing the power supplies for the red light LED particles and the blue light LED particles, and the controller provides required illumination for promoting the plant growth by cooperating with all the parts. By means of the lamp capable of promoting the plant growth, the illumination required by the plant growth is automatically supplemented, and errors caused by manual adjustment are avoided. According to the lamp capable of promoting the plant growth, distribution power of the red light and the blue light is set according to the growth period of the plant, the light source is effectively utilized, and the energy conservation and the environment protection are achieved.

Description

technical field [0001] The invention relates to the technical field of lighting lamps, in particular to a lamp for promoting plant growth and a method for promoting plant growth by using the lamp. Background technique [0002] Light environment is one of the indispensable environmental factors for plant growth and development. Controlling plant morphogenesis through light quality regulation is an important technology in the field of cultivation. [0003] Effect of spectral range on plant growth: [0004] 280nm--315nm has minimal impact on morphology and physiological processes [0005] 315nm--420nm has less chlorophyll absorption, which affects the photoperiod effect and prevents stem elongation [0006] 420nm--500nm has the largest absorption ratio of chlorophyll and carotenoids, and has the greatest impact on photosynthesis [0007] The absorption rate of 500nm--620nm pigment is not high [0008] 620nm--750nm chlorophyll has a high absorption rate, which has a sig...

AI Technical Summary

Problems solved by technology

[0007] The absorption rate of 500nm--620nm pigment is not high

[0009] 750nm -- 1000nm has low absorption rate, stimulates cell elongation, affects flowering and seed germination

The plant growth lamp has the following problems: 1. The light intensity of the plant growth lamp cannot be adjusted according to the change; 2. The proportion of light of different wavelengths required by the plant cannot be adjusted according to the plant growth cycle, such as during the growth and development period of the plant and flowering, fruiting The specific gravity of the wavelength of light required during the period is different. If it cannot be adjusted in time, the plant growth lamp cannot be used with maximum efficiency; 3. The process of making the light source is complicated, and if it is damaged, it is not easy to replace
