Industry 4 major trends LED enterprise will be two intelligent development
In the Internet concept, the German academic and industry first proposed the &ldquo at the Hannover industrial exhibition in 2013. The core of this concept is &rdquo (CPS), which integrates all kinds of digital information, resources, products and people, so as to establish a highly efficient and fast information, digital products and services. This concept was quickly spread to Europe from Germany and began to affect the world.
1, the content of intelligent LED lighting
The traditional LED had already appeared in 1962, and a LED product can only emit a low luminosity, and now the light has been spread all over the visible, infrared and ultraviolet light. In recent years, with the emergence of new technologies such as Internet, cloud computing, people are not satisfied with the basic functions of high brightness, low energy consumption, long life and low power, but more to LED and advanced things and cloud computing technology, from human psychology, physiology and sociology, considering the individual comfort, light biological safety and other conditions to improve learning, working and living conditions of the social benefits of reducing air pollution protection environment, that is LED intelligent.
And in the context of industry 4, combined with the traditional LED homogenization of the past ten years of serious overcapacity problems, we have not just the development and demand of LED products is still in the light of their own performance, but efforts to combine with other industrial technology, in order to obtain a composite function of LED smart light, thus the LED industry capacity to carry out the diversion. So far, there are two main diversion direction. The first is to break through in the field of agricultural lighting, and the second is to develop the field of optical communication.
2, LED agricultural intelligence
In agriculture, we know that light is one of the most important environmental factors for plant growth and development, and it has a direct regulatory effect on the growth and development of plants. Currently known environmental factors, such as relative humidity, temperature, light intensity and light quality, are closely related to the growth and development of plants. In these factors, the quality of light directly affects the growth of plant stem, lateral branching, leaf growth and pigment deposition, and other major growth indicators. And the integration of these optical quality, mainly through the continuous intensity of red light, blue light, and the path of the hormone signal on the plant has a profound impact on the physiological response and thus the plant's growth and development plays a controlling role.
Using LED as the advantages of artificial light source for plant growth is that it has high energy conversion efficiency, DC power supply, small volume of products, is the use of, long service life, determine the wavelength and light intensity / mass ratio to reconcile low heat output. Some of the crops has been LED light culture, such as pepper, spinach, wheat dwelling, etc.. The research shows that the red light has an important effect on the development of the organs of photosynthesis in plants, and it can also increase the amount of starch in plants. It is also reported that the use of far infrared radiation can improve the antioxidant properties of rice husk. This indicates that the specific light radiation can increase the nutritional composition of food.
Overall, in the long run, there is a trend to replace the traditional lighting source with LED. Intelligent lighting system based on LED can be widely used in biological research of plants or animals; and this kind of intelligent system can also be used to determine the intensity and quality of light intensity for specific plant growth. It can be predicted that the agricultural intelligent system based on &ldquo will be the LED, the industrial 4.0&rdquo, and the important embodiment of the application in agriculture.
