Abstract
The invention discloses a light-emitting diode (LED) four-color light supplemental device of a plant. The light supplemental device of the plant comprises a red-light LED array, a blue-light LED array, a far-red-light LED array, a green-light LED array, a substrate 5 and a control circuit, wherein the red-light LED array, the blue-light LED array, the far-red-light LED array and the green-light LED array are sequentially and fixedly arranged on the substrate 5, and the control circuit is used for controlling the red-light LED, the blue-light LED, the far-red-light LED, and the green-light LED to supplement light. According to the light supplemental device of the plant and a light supplemental method of the plant, the four-color light LED with a specific specification is selected, not only are colored lights which have a plurality of wavelengths and specific effects on plants by means of centralization of a variety of photosynthesis considered, but also economy and practicability are further taken into account. Meanwhile, considering the comfort of the human eyes, the four-color light LED with normal colors such as red, blue, far-red and green are selected. When the color lights are selected, according to the power of the selected LED with various colors, a reasonable ratio of R / B, R / FR and R / G can be obtained through the control circuit, thus the photosynthesis of the plant and the comfort requirement of the eyes of human can be met, and the requirements of orientation of cultivation of the plant with the need of participation of human can be better met.
Description
technical field [0001] The invention relates to the field of application of LEDs in non-sunlight seedling cultivation in agriculture, and in particular to a device for supplementing light for plants. Background technique [0002] Different wavelengths of light have different effects on plant photosynthesis. The light energy absorbed by the light required for plant photosynthesis in the visible light spectrum (380-760nm) accounts for about 60%-65% of its physiological radiation light energy, of which Mainly red and orange light with a wavelength of 610-720nm (peak of 660nm) (accounting for about 55% of physiological radiation) and blue and purple light of wavelength 400-510nm (peak of 450nm) (accounting for about 8% of physiological radiation) is the absorption peak region. The 520-610nm (green) light has a very low rate of absorption by plant pigments. Far-red light (710nm ~ 740nm) LED has a great influence on plant morphogenesis and regulation of plant height growth. The...
