Problems solved by technology

[0004] 1. The research and use of current light sources are mostly limited to the visible light (400nm-760nm) region, while ignoring the impact of electromagnetic radiation other than the visible light band on biology, and the selectivity is small in practical applications;
[0005] 2. If figure 1 As shown, many LED chips with different wavelengths are generally used to fit the target spectrum. It can be seen that there are overlapping bands between the wavelengths used to fit the target spectrum. The more overlapping bands, the more waste of efficiency. In order to make the fitting The curve is closer to the target spectrum, and the number and specifications of LED chips in the light source will inevitably increase further, thereby increasing manufacturing costs and further reducing performance
Moreover, the target spectral curve is only a relatively optimized spectrum that is more suitable for biological growth. In fact, there is a maximum absorption peak in the demand of biological electromagnetic radiation. The way of fitting the spectrum is essentially similar to that of The method of spreading the net to cover the maximum absorption peak of the electromagnetic radiation by the organisms has greatly improved its efficiency compared with blind lighting, but there is still a large waste inevitably.

Embodiment 1

[0034] Such as image 3 Shown is the emission spectrum diagram of the all-electromagnetic wave control device for the purpose of controlling the flowering period of strawberries and improving the fruit setting rate. It can be seen that the characteristic peak wavelengths of its emission are two, respectively 660nm and 730nm, and its half-wave width is 15nm. Its characteristic peak wavelengths of 660nm and 730nm are obtained by mixing quaternary semiconductor materials to form different energy bands, and electron transitions in different energy bands generate radiation.

[0035] Such as Figure 4 Shown is the comparison table of using other LED plant growth lamps and the full electromagnetic wave control device adopted in this embodiment. In this table, other LED lamps are integrated with multiple chips to fit the tomato growth spectrum, so its The power values ​​are all large, the highest power value reaches 70W, and the least is 15W. Such as Figure 5Shown is the growth s...

Embodiment 2

[0037] Such as Figure 6 Shown is the emission spectrum of the full electromagnetic wave control device with leafy vegetables as the cultivation object. It can be seen that there are two characteristic peak wavelengths of its emission, which are 450nm and 660nm respectively, and its half-wave width is 15nm. By adjusting the radiation intensity and ratio of the two peak wavelengths, the quality and yield of leafy vegetables can be improved. When the blue-red light ratio is 100:0, the characteristic wavelength of 450nm plays a role to promote the synthesis of proteins and organic acids; when the blue-red light ratio is 66:34, it stimulates the biomass accumulation in the roots and increases the phenolic content of lettuce. Promote the growth of leafy vegetables after transplanting; when the blue-red light ratio is 34:66, increase the content of vitamins and anthocyanins; when the blue-red light ratio is 0:100, the characteristic wavelength of 660nm plays a role, and the photosyn...

Embodiment 3

[0039] Such as Figure 7 Shown is the emission spectrum of the all-electromagnetic wave control device with white-feathered broiler as the training object, which is controlled by the PWM module to emit only one characteristic peak wavelength of 540nm (radiation intensity is 36molm-2s-1). Such as Figure 8 Shown is the effect of white light, red light, blue light and green light (540nm) on the feed-to-meat ratio of white-feathered broilers. It can be seen that under the irradiation of the peak wavelength of 540nm, the feed-to-meat ratio of white-feathered broilers is significantly reduced.

Abstract

The invention discloses an efficient large-wave-band biostimulation device. The electromagnetic wave radiation wavelength of the device is between 265 nm and 800 nm, the growth and development of organisms are promoted or suppressed by transmitting electromagnetic waves with specific characteristic peak wavelengths to the organisms, and the semi-wave peak widths of the electromagnetic waves provided by the device are extremely narrow, so that the maximum stimulation effect to the organisms is realized by using the minimum energy, and great energy saving is realized. Furthermore, the radiation intensity of each wave band is regulated and controlled in the manner of adjusting drive current at a duty ratio, so that energy consumption is further reduced while light supply according to time and requirements for the organisms is realized. The efficient large-wave-band biostimulation device can be applied to the fields of plant culture, animal breeding, medical treatment and the like, and has extremely high economical efficiency and practicability.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to a high-efficiency large-band biostimulation device. Background technique [0002] As an ecological factor, light is increasingly accepted and valued for its impact on living things. Taking plants as an example, light is not only used as an energy source to control the photosynthesis of plants, but also as a trigger signal that affects all aspects of plant growth and development, from seed germination to deetiolation to the effect on vegetative morphology (stem growth). and leaf extension), onset of the 24-hour rhythm, gene expression, gravitropism and phototropism, etc. Taking animals as an example, light has a very significant effect on regulating the endocrine of animals. When the ratio of day to night changes greatly, the control of hormones in animals will be disturbed, causing discomfort. For example, in birds, it is generally believed that birds have two photoreceptors: one is th...
