Talking about the "breaking and building" of lighting and IOT

IOT has become a hot topic in recent years, which is due to the rapid development of low-cost sensors, microprocessors and wireless communication services. Once these IOT platforms are applied in any environment, massive data on energy use, environmental conditions and human activities will be generated. These data are of great value and can be used to provide new application functions. These functions can be simple or complex; It's as simple as an instruction to smart home products, "is the light still on in Jimmy's room?", It is as complex as an instruction sent to the building management system to control the lighting, air conditioning, HVAC, security system and space use of the whole building (the instruction control of space use usually requires real-time processing of space usage, temperature, carbon dioxide level, humidity level and other data). Statistically speaking, the number of IOT sensors is more than three times that of the global population (as shown in Figure 1), and the number of new IOT devices is expected to grow rapidly

IOT platform is becoming a disruptive force in the lighting industry, because lighting system has three attributes coveted by key parts of the emerging IOT Market: ubiquity, favorable position and energy consumption. In IOT, lamps and lanterns can be regarded as a dynamic system, which includes one or more "objects" (usually sensors), and these objects feed data to the control system through wired or wireless connections. Sensor data can be processed through cloud computing, but it is more likely to be processed locally (in lamps, rooms or other places in buildings) to shorten the time (delay) between sensing and system response and solve network security problems. The value of IOT to lighting companies comes from the use of sensors in lamps for data generation, creating intelligent services that consumers and building managers believe are indispensable. This is becoming more and more attractive to lighting companies, because solid-state lighting (SSL) itself is a disruptive technology, which is increasingly commercialized, and investors and shareholders of lighting companies are also looking for new non lighting ways to achieve revenue growth

these constantly developing new market opportunities mean that lighting supported by IOT is gradually entering the commodity lighting market, and almost all major lighting manufacturers and many small start-ups can provide such products. IOT products in the lighting industry are usually called "interconnected" or "intelligent" lighting systems. Most lighting systems supporting IOT include simple passive infrared (PIR) occupancy sensors and daylight sensors; But in the future, they may include more advanced integrated sensors (such as carbon dioxide sensors, infrared imagers, radar sensors). At present, different interconnected lighting products cannot be fully "interoperable", so products from different suppliers usually cannot work together on the same IOT communication protocol, even if they use an "open" (non proprietary) communication platform. Interoperability has been widely recognized, and IOT industry organizations are working to solve this problem

as IOT gradually penetrates the lighting market (and almost all other markets), we need to make significant progress in analyzing all the data generated by sensors. The analytical work of digesting information to provide value-added services will increasingly rely on machine learning (ML) and artificial intelligence (AI) to maximize the benefits of IOT platforms. Although ml/this will make the 3D printing structure obtained by reaction have no reprocessing ability, AI system itself is a disruptive technology, but they have just begun to be put into practical application. They are developing rapidly in other markets, such as autonomous vehicle, healthcare analysis and voice activated smart home technology, and will be applied to adaptive control of lighting and building management systems

summarizing the current situation, the curse of the past "may you live in an interesting era" certainly applies to today's entire lighting industry. This is the pain caused by the major disruption of three intertwined technology platforms: 1) constantly introducing new solid-state lighting technology, 2) gradually introducing the concept of IOT based on lamps, 3) using increasingly complex ml/AI embedded systems for lighting (and building management) control. Although practitioners in the lighting market will face challenges in the face of these upcoming changes, many people have realized that the long-term trend is clear:

lighting cannot escape the future IOT

IOT based services are the business areas of networking, telecommunications and information technology companies, which transmit sensor data to end users who provide value-added data services. These companies will ultimately address a wide range of interoperability issues, network platforms, privacy/network security, and data ownership management. Non lighting companies have strong capital (see Figure 2), have invested a lot of money in IOT and ml/AI technology, and are most likely to monetize an interconnected future - including lighting. Large alliances in the IOT industry are solving a wide range of IOT applications, but few of them are lighting companies

how should lighting be linked to IOT

unless lighting companies can maintain control over sensors and slots, the answer to this question is likely to be few. Of course, the design of lighting system will always be important, no longer just for energy conservation, but more and more considering human factors and possible Li fi technology. The consideration of energy is still very important, but it is only limited to the control level, and finally turns to the automatic lighting control system. The system will rely on complex occupancy sensors, IOT connections and ml/AI data analysis, use the concept of light response to save energy, and use occupancy sensing, tracking sensing and daylight sensing methods to provide color adjustable lighting design to improve people's health

does lighting and IOT have a bright side

4. Requirements for experimental machines and instruments:

there is still a lot of room for innovation and improvement in the lighting industry. This can come from embracing the virtual simulation of how to realize the teaching process of IOT, which is the key to whether virtual instruments can be introduced into the course teaching, including the continuous development of new lighting shape factors and new optical devices that can effectively carry out dynamic color mixing and light pattern shaping (such as lensvector and others). By working closely with IOT, it and lighting design software tool developers, the lighting community (designers and manufacturers) can help shape the future of the connected lighting industry

perhaps one of the best opportunities for lighting companies to benefit from the future of IOT is to have sensors and explore how to make the lighting of lamps become an integral part of the sensory ability of lamps. There is a new method to use the reflected light sensing of digital lighting to perform high-precision occupancy tracking and even generate pose detection data (such as standing, sitting, squatting). Through the improved lighting software design tool, taking into account the spectral reflection of the space surface, the light dose that compensates for glare and human eye health and well-being, the better lighting spectral power distribution can be calculated more accurately than other non light based technologies. When the lighting system can perceive its environment economically and effectively (ideally using low-cost color light and time of flight measurement to protect privacy), lighting will become an integral part of any IOT solution

in addition to ubiquity, advantage and energy consumption, the lighting industry can also generate valuable lighting based data and information for lighting control systems and other IOT systems in building management, health care operations, communications, and even gardening. By making perceptual lighting a requirement for the operation of IOT system, IOT solutions will need to adopt lighting system design and connection to achieve the maximum social benefits. However, if the lighting industry transfers the development and ownership of slots (and terminals) and sensors (and data) to other enterprises outside the lighting industry, it will miss major market opportunities. Lighting will gradually become a non intelligent commodity plug-in, and make wedding clothes for others' future IOT business

column comments:

an important direction mentioned in the article is that lighting will be closely combined with artificial intelligence and machine learning, and become a crucial link in the building IOT system. In fact, IOT lighting has a clue to the development of the whole community environment and even smart city. Philips Lighting has begun research and development in this field, and other lighting companies (such as gooe, low volatility and allowable emissions E) are also making efforts in this regard. Many lighting practitioners, including me, believe that IOT lighting will also be combined with humanistic lighting in the future, so that the personal lighting environment can be customized by users, and the public lighting environment can be intelligently adjusted to ensure the health and well-being of the public. Therefore, the gradual integration of IOT lighting and humanistic lighting will also become the only way for the development of the lighting industry

the article also puts forward a technical warning: the development and ownership of the physical interface (slots, terminals, etc.) technology and logical interface (sensor data transmission, translation, etc.) technology of lighting products must be within the industry. We can strengthen industry cooperation to make the physical and logical interfaces of lighting products meet the development needs of other peripheral equipment, but we cannot give up control of this field, because the physical and logical interface technology will have a very important impact on the research and development of lighting control protocols. If the interface technology is backward, if there are advanced control protocols developed in the lighting industry, I'm afraid it will not be effectively popularized because of the lagging interface technology. In short, the lighting industry should be a "sovereign" field. We should have the greatest freedom of self-development, and at the same time, we must develop and communicate with other external fields
