At present, more and more facilities have installed such led high pole lights. Actually, it's not just lamps. The application of led lights is very wide. It can be said that as long as there is a need for light, they can be replaced by led high poles, which can be roughly divided into led manufacturer lighting, led commercial lighting, led advertising lighting, led agricultural lighting. Especially led agricultural lighting includes plants, animals, algae. At present, it is mostly applied to plants, covering the cultivation, growth, flowering, and fruiting stages of plants. With the contamination of available land and scarce resources, growing vegetables indoors, flowers are becoming more common and can be grown off-season. Nowadays, the development of science and technology has transformed modern high-tech agriculture from food in the past, and this breakthrough point is: the successful application of led high poles in current agriculture.
Mainly used in plants are high-pressure sodium lamps, metal halide lamps, most of which are hundreds of watts and kilowatts. These light sources contain many unnecessary wavelengths, their biological light efficiency is very low, and energy consumption is large, which are absorbed by plants. Only a dozen percent, and harmful gases will be emitted during use. LED has the advantages of narrow wavelength, pure light quality, high luminous efficiency, rich wavelength types, convenient spectral energy modulation, and low heat generation, small volume, long life, etc., which is convenient for concentrating the wavelengths required by plants for balanced close-range irradiation. For plant production, intensive plant production can be achieved with high efficiency, low heat load and compact space, reducing the use of plant hormones or other chemicals.
