Electric energy into machinery to promote the fan rotation
The rotor of the DC cooling fan includes the DC cooling fan blades, which is the source of the air flow, the fan shaft, which is used to support the balance blade rotation, the rotor ring, the permanent magnet, the key to switch the speed of the magnetic level, Fixed magnetic ring. In addition, it also includes the support of the spring, through which the components are fixed to the tuberculosis to rotate the entire part, the motor part, the production rotation direction, and the dynamic size of the rotation speed key. Its speed performance, control is simple. DC Fan Portable Dc Fan ,Dc Usb Led Fan, 12 Volt Dc Fan, Dc Ceiling Fan Ningbo APG Machine(appliance)Co.,Ltd , http://www.apgelectrical.com
Chen Yansheng, vice chairman and secretary general of China Lighting Association, said that since Edison invented the light bulb more than 100 years ago, the lighting has experienced the heat source and gas source, and entered the solid-state light source stage at the beginning of this century. It can be said that every advancement in lighting is the result of innovation. Nowadays, with the application of LEDs to the field of lighting, digital technology and interconnected technology are more easily integrated, and intelligent lighting has begun to enter the public eye.
Intelligent lighting is the solution <br> <br> intelligent lighting system concept is very young, the history of Europe and America and other developed countries, but also intelligent lighting even in just a few years only. However, there is no doubt that smart lighting will have an important impact on the upgrading of the lighting industry and the improvement of people's lives.
"For the society, intelligent lighting will provide new ideas for energy saving and emission reduction; for the people, intelligent lighting will improve the living environment and quality of life, creating a more comfortable lighting environment for people." Chen Yansheng said that in recent years, Intelligent lighting has achieved significant growth and is valued by the industry. The United States established the Intelligent Lighting Engineering Research Center in 2008. Since 2011, Europe has held an annual intelligent lighting conference. Although the country is slightly behind the developed countries, many companies are already working on smart lighting.
However, Chen Yansheng believes that the current intelligent lighting is still in its infancy, and everyone is groping forward, so the products produced are also relatively primitive, such as the so-called smart bulbs. In fact, intelligent lighting is not a simple light bulb or lighting equipment. In the future, true intelligent lighting should be a system solution, which is an intelligent lighting system that varies with different lighting environments.
For example, he said, assuming a bathroom, no one is lit, but when the person opens the door, the light inside will automatically light up. This is the simplest example of intelligent lighting. Another example is the underground parking lot. Under normal circumstances, the illumination of the light is not high. When the car comes in from the entrance, the forward passage will be illuminated by strong light; when the car passes, the light will automatically darken and no human operation is required. And like conference room lighting, the lighting will change in time according to different conference scenes such as discussion and screening PPT.
Challenges into opportunities rational development of intelligent lighting intelligent lighting <br> <br> prospects, the industry has been identified is the future development trend of lighting. At present, many lighting companies are planning to transform and upgrade to smart lighting.
At present, the intelligent lighting industry is in a state of full bloom, such as infrared transmission, WiFi, Bluetooth, ZigBee, etc. The establishment of standards requires a process, and there is no consensus yet. However, the ZigBee network protocol has the highest voice in the industry and is expected to become the mainstream in the future.
Domestic companies are entering the field of intelligent lighting, and opportunities and challenges coexist. Chen Yansheng pointed out that enterprises must turn challenges into opportunities, constantly adjust and optimize their talent structure and knowledge structure. On the one hand, they actively introduce professionals in Internet and communication; on the other hand, they must cooperate with other enterprises and other fields, and actively participate in international Exchange and learn from foreign counterparts. At the same time, he reminded some companies that are on the sidelines, should not blindly invest, and must rationally look at the current hype of intelligent lighting.
Chen Yansheng hopes that all sectors of the society will create a healthy and rational development environment for intelligent lighting, so that enterprises can carry out research and development work with greater concentration and pragmatism. 
Cooling fan, is through the DC voltage and electromagnetic induction, from electrical energy into machinery to promote fan rotation fan.
Rely on the coil and IC constantly switch, induction magnetic ring from the drive fan rotation.
Challenge to Opportunity Intelligent Lighting Needs Rational Development
Innovation is the driving force for economic and social development, and innovation has far-reaching implications for all walks of life. The same is true for the lighting industry, and the active implementation of innovation is crucial to the further development of the intelligent lighting industry.
