HC Security Network News in 1995, listed on Netscape's browser makers officially opened the curtain of the Internet investment boom, and was followed by frenzied speculation in the capital market for Internet companies. At that time, there was a cartoon saying that several beggars were begging in New York, and people passing by gave them some coins from time to time. One of the clever shackles is different. He hangs a sign on his chest, which only says .com, and he receives one after another cash check. Burning money is a new term coined in this context, which is the Internet bubble that was said that year.
What changes will the lighting Internet of Things bring to the LED industry?
For the Internet of Things as an extension of the Internet, it naturally follows the general principles of the network economy. As a new thing, the Internet of Things does not have some basic conditions for its current development environment; however, in some cases people need to increase the scope of his ability control, and an important role of the Internet of Things is to increase people's ability control. range. So, is the Internet of Things a bubble or a technological revolution? What changes will the LED industry produce in the future?
For investment, the bubble is only related to the enthusiasm of the investment, and has nothing to do with the object being invested. Even the best investment investors face a crazy investment, there will be a so-called bubble. Take Microsoft as an example, it is undoubtedly an excellent investment target with good prospects and good revenue. But if fanatical investors fire Microsoft's share price to 100,000 yuan, then Microsoft will become a bubble in the capital market. From an industry perspective, there are still different voices. Many people believe that the time for launching the Internet of Things is not yet mature. In fact, this is the result of observing the Internet of Things from a narrow perspective.
I think that the time to start the Internet of Things is not yet mature. It is to evaluate the Internet of Things from the perspective of whether a company that is a production unit should enter a new field. From this perspective, their views are justified. Just as our country has established a development zone, the first thing to do in the development zone is to build the basic environment, including water, electricity, access, and land. If even the water and electricity have not been opened, it is obviously unrealistic to say that this development zone is a fertile land suitable for investment.
The objection of the conclusion is the difference in observation angle
For the Internet of Things, what we lack now is such an objective environment suitable for development, mainly reflected in the following aspects. First, the standard issue has not been resolved. This is equivalent to a game without rules, not only makes the entrant feel overwhelmed, but also hides huge risks, the initial investment is likely to disappear because of the standard changes. Second, there are still huge obstacles in terms of hardware devices. This is mainly reflected in the fact that various sensors have not entered a virtuous cycle, both technically and in terms of cost, and these depend on the market for cultivation. Again, it is also difficult in terms of software. The key technology of data processing, artificial intelligence technology, is far behind the requirements of people at the current level. More importantly, the concept is still under the guidance of a separate, independent and closed mind.
Without versatility and interactivity, there is naturally no need for interconnection. Who will access an endpoint that has no effect on itself? A major feature of the network economy is economies of scale. A large number of users and a large number of applications are prerequisites for the utility of the network economy to be exerted. For the Internet of Things as an extension of the Internet, it naturally follows the general principles of the network economy. As a new thing, the Internet of Things does not have these basic conditions in terms of its current development environment. Therefore, the Internet of Things is considered to be an advanced concept and understandable.
New forms of urban innovation
The current Internet of Things is similar to the beginning of the Internet development in the past. If there is no warrior who dares to innovate, the Internet of Things will undoubtedly become the flower in the mirror. Pies don't fall off the sky by themselves. Under the support of demand, most of the problems facing the Internet of Things are now overcome. Technical problems can be solved through innovation; cost issues can be solved by scale; number of users can be solved by increasing the application; business model problems can be solved through practice.
Smart city is the result of a new generation of information technology innovation applications including Internet of Things, mobile Internet, wireless communication, big data, cloud computing under the latest urban innovation form.

From infrastructure, IoT integration, system application, and terminal reproduction, the integration, integration, integration, and integration of software and hardware systems deconstruct the challenges and pain points of urban construction and achieve the goal of smart city construction.
Large integration means that a smart city is a giant system. In terms of structure, including infrastructure, information resources, application services, security systems, institutional mechanisms, standards and norms, it also includes economic, social, cultural, political, and ecological fields. Large integration means that a smart city is an organic system. Information systems in various fields are not simply stacked, but a scientific system integration method is adopted to realize the organic connection and interconnection of isomorphic and heterogeneous systems. Large synergy means that the construction process of a smart city is a dynamic process. Each system can work together to efficiently handle various types of affairs. At the same time, various systems are scalable and open, and thus can be developed and upgraded.
The focus of smart cities is on smart services and management. The systemized and networked smart city terminal can not only collect various big data, but also serve as an end-use application service for people's livelihood. It can be extended to every corner of the city with precise, visible and interactive effects, such as streets. , commercial districts, plazas, schools, hospitals, communities, tourist areas and other places to support the city's safe and reliable operation.

Visible light communication system
A LED light connects the world
Light can be illuminated, can also transmit data and images, use the light to access the Internet, no longer the plot of science fiction movies! Under the support of the Technical Department of the Ministry of Economic Affairs of Taiwan, the "LED visible light communication system" developed by the Industrial Research Institute, the visible light communication module The equipment is on the LED luminaire. Through LED illumination, it can reach a transmission capacity of about 100 Mbps per second when the transmission distance is about 3 meters, so that the LED lamp has the characteristics of energy-saving lighting and intelligent communication, providing broadband Internet access, indoor navigation and service. Personnel location management. Combined with the mobile phone, it can also assist the store to carry out commercial applications such as positioning services, so that LED is not only the popular fried chicken in the lighting industry, but also the star of the next generation wireless communication!
At present, the "visible light communication system" mainly uses LED lamps with low power consumption and long life, and transmits data through the visible light emitted. Therefore, in addition to the communication network and the LED light link at the transmitting end, and the data is converted and transmitted with visible light, and at the receiving end, a visible light receiver is also provided for receiving the interpreted data and transmitting it to a computer or a mobile phone and the like. in. If there is a need for data uploading, it can be transmitted by means of infrared, Wi-Fi or increased visible light depending on the application field.
This system integrates communication and lighting, allowing the communication of data to have a new spectrum; and the visible spectrum of electromagnetic waves, not only does not require expensive spectrum license (License-Free), not with existing Wi-Fi, Zigbee, Bluetooth and other communication technologies use the same frequency band to avoid mutual interference, and even harm to the human body. It is more suitable for use in hospitals, airplanes and other fields that are more susceptible to electromagnetic waves.
The "visible light communication system" developed by the Institute of Information and Communication of the Industrial Technology Research Institute mainly uses LED lamps with low power consumption and long life, and transmits data through the visible light emitted. In addition, since the data transmitted through visible light and the LED light wave have directivity and a certain illumination angle, as long as the receiving end leaves the illumination range, or the visible light of the LED is blocked, the transmission will be immediately interrupted and suspended, unlike Wi- Communication technologies such as Fi can be used in a wide area. The "visible light communication system" is more capable of data and network security, and can be used in conference room communication systems that require confidentiality. At the same time, because the LED's illumination range is limited, it can be effectively recognized by the light, and it can be used as a tool for accurate indoor positioning.
The many features of this technology can be used in a wide range of applications. For example, in the restaurant to improve the efficiency of the dispatcher, in order to serve the needs of the nearest guests, or to ensure that the building security personnel have inspections at important locations. In various stores and stores, you can also send merchandise offers or promotional information through the "visible light communication system", and consumers can receive messages only through their mobile phones. This time in the demonstration of the declassified technology treasure, it is subtly a five-dimensional space for the alternative display of communication channels. Other special application fields include signal transmission in the water, allowing divers to transmit sound and other information through the light, to navigate the water, and to improve safety. Or, for the monitoring of the state of the sea, the application of underwater engineering, etc., it is also possible to store the image and other data first, and then collect the underwater unmanned vehicle to collect the data. At this time, it can be transmitted through visible light and reduced. The cost of building a network cable.
