The invention relates to an LED lamp with an adjustable light emitting spectrum. The LED lamp comprises a center bracket, a left bracket, a right bracket, a first blue light chip with an emission wavelength of 430nm and a second blue light chip with an emission wavelength of 453nm. The first and second blue light chips are both electrically connected with the center bracket. The outer sides of the first and second blue light chips are provided with a red fluorescent powder region having forwarding central wavelengths of 642nm and 662nm and being formed by mixing red fluorescent powders with forwarding central wavelengths of 630nm and 670nm. The first blue light chip is connected electrically with the left bracket. The second blue light chip is connected electrically with the right bracket. The outside of the red fluorescent powder region is coated with a transparent packaging portion. The upper ends of the center bracket, the left bracket and the right bracket are fixed in the transparent packaging portion. The LED lamp with the adjustable light emitting spectrum can control the first or second blue light chip to work independently for light supplement for different plants, and is high in the light utilization rate and good in versatility.
Description
technical field [0001] The invention relates to a light source for supplementary light growth of plants, in particular to an LED lamp with adjustable emission spectrum. Background technique [0002] At present, there are more and more companies making plant growth lights. From the appearance alone, it is impossible to see the pros and cons of the products, but from the technical point of view, they are quite different. Some products simply arrange red light beads and blue light beads interspersed to form the so-called superimposition of red and blue light spectra; Arrangement of the quantity, combined into red light, blue light, and far-red light and superimposed in a certain proportion; some products even superimpose many spectra of different wavelengths into the so-called full spectrum. [0003] We know that the chlorophyll that plants participate in photosynthesis is mainly divided into chlorophyll a and chlorophyll b. Whether it is the spectrum received by chlorophyll a...
