Industrial wisdom has become an irreversible trend of the times. In the lighting industry, smart lighting has leapt to the mainstream development trend. Taking LED lights as an example, before 2014, the primary goal of the lighting industry was to increase power. However, after the power reaches 100 lumens per watt, the upward speed has slowed down. The primary goal of research and development is to expand the application level and focus on Smart lighting related fields. According to statistics, in 2016, the penetration rate of LED lamps was about 31%. By 2019, the penetration rate of LED lamps was estimated to be about 49%. It has been able to compete with traditional lighting, with an output value of about 72.6 billion US dollars, of which wisdom lighting The output value is estimated to be about 8.7 billion US dollars, the ratio is only about 12%, there is still a lot of room for growth. At present, the ratio of smart lighting used in the commercial market and the home market is 62% and 26% respectively. In a few years, the ratio of the household market will gradually increase. It is estimated that by 2019, the ratio of the two will be adjusted to 50%. 32%, the trend of growth and decline is very obvious. In fact, wisdom lighting has been seen everywhere, people are no strangers. For example, the mobile phone can control the brightness and brightness of the light bulb through digital control, and the lighting equipment of several spaces uses infrared detection. When someone enters, it will automatically turn on immediately; when everyone leaves, it will automatically turn off. However, true intelligent lighting does not require human control, and can accurately sense the surrounding situation and signal changes, and automatically make appropriate adjustments. Even different people enter the space of the device's intelligent lighting, and can release different light according to their state. Therefore, the current wisdom lighting technology is still in its infancy, and the realm of wisdom lighting is still far away. In recent years, more and more international manufacturers have invested in smart lighting technology and application research and development. As smart lighting is a new field and uses many ICT components, participants in addition to lighting manufacturers, including many ICT manufacturers, the competition is fiercer, and in the global smart lighting industry supply chain, Taiwanese manufacturers can borrow hardware. The device card position is more advantageous at the package end, but at the illumination end, it is still weak. Another weakness of Taiwanese manufacturers is that they are less adept at creating, imagining, and developing new applications for smart lighting. In the foreseeable future, Taiwanese manufacturers should stick to and strengthen their existing advantages and make up for the weak. When there is much to do, smart lighting can also become a new niche for the lighting industry and the ICT industry. Smart lighting can also be classified as a part of the Internet of Things. As the Internet of Things is on the rise, the level of attention is increasing. According to the definition of the Internet of Things, everything can be interconnected by each other. According to the new generation network protocol IPV6, it can provide 2 128-square-degree websites. It is said that even if everything is as small as a grain of sand, it has its own website. Smart lighting gives the Internet a link, allowing LED bulbs to have their own web address and form a network, which has far more functions than traditional lighting. In addition to lighting, smart lighting can also be used for communication and positioning. In the era when wireless communication is not yet popular, when the ship is docked, the crew must continue to use the manual method to light the Morse code and send messages to the port staff, which can be called visible light communication. Modern visible light communication can help with electronic circuits. The speed is 100 million times faster than the traditional method, that is, the amount of information can be transmitted more than 100 million times in the same time. Communication with smart lighting does not require turning the LED light on and off. As long as the brightness of the light bulb changes slightly, the sensor can sense it. In terms of technology, it is only necessary to control the current intensity, and the technology is not difficult. At present, because smart lighting is not widely used in communication, dimming and communication functions belong to two chips, and it is expected to be integrated into one in the future, which has little impact on volume and cost. However, in wireless communication, smart lighting competitors, such as WiFi, are vulnerable to the exclusion of existing technologies, and it is not easy to get behind. Therefore, for the extended application of smart lighting, the Institute of Technology prefers positioning, especially indoor positioning, and has cooperated with hospitals such as Changhua Christian Hospital to develop indoor positioning systems. Outdoor positioning has become quite popular, and the accuracy has been increasing. The highest penetration rate is GPS, but indoor positioning has just started, and the accuracy is not good. The technology most commonly used for indoor positioning is WiFi, but its accuracy is only 5 to 10 meters. The principle of intelligent lighting for indoor positioning is that each bulb has an address, and its accuracy can be improved to Within 1 meter, the probability of error is greatly reduced. Under the support of the Ministry of Economic Affairs and Science and Technology Project, the Taiwan Industrial Research Institute and the Changhua Christian Hospital jointly developed the “Smart Hospital Nursing Handover VLC Positioning System†to help the nursing staff reduce the shift time. Previously, every time the nurses of Changhua Christian Hospital handed over, because the various instruments were located in different positions, it was just a matter of counting the equipment. It took about ten minutes. In the long run, the time spent was considerable, and the nursing staff was exhausted. In order to make the nurses work more smoothly, Changhua Christian Hospital tried a variety of solutions. This year, Changhua Christian Hospital installed the “Smart Hospital Nursing Handover VLC Positioning System†and installed LED lights in all corners of the hospital to locate the instruments with LED lights. When the nurses are on duty, they only need to browse the electronic shift table interface at the nursing station. It can be seen whether the instrument is positioned, and the shift time can be shortened to 2 minutes at the earliest. Considering that the hospital is not every space, it lights up like a nursing station all day long; Changhua Christian Hospital is equipped with LED lights at the door of each room, and the movement track of the instrument can be confirmed through the "Smart Hospital Care Handling VLC Positioning System". Even if some spaces are turned off, the instrument inventory can be successfully completed, the caregiver can shift, and there is no need to turn on the light count. In addition to medical institutions, Taiwan Institute of Technology also actively promotes the development of new applications of smart lighting with other industries, with a view to reducing the manpower, material resources, or service quality required. The next industry to be expected is to be a museum or art museum. . Many of the professional guides of museums and art galleries have been replaced by low-cost audio guides. When people visit museums and art galleries, they will rent an audio guide. When they come to a display or art, they will hear the voice introduction and related information as soon as they wear the headphones of the audio guide. The Taiwan Institute of Technology is trying to replace the audio navigation equipment with a tablet computer, replacing the voice data with images and video materials, which makes the visitors more impressive. In the future, if museums and art galleries install smart lighting positioning systems, and LED lights are installed in each exhibit and artwork, the tablet will automatically play the image with the theme when the visitors stop at the exhibits and artworks. ,video material. In addition, because the outdoor positioning is more GPS, the system and interface are different from the intelligent lighting positioning system. The Institute of Technology has begun to integrate the two, so that the outdoor positioning and indoor positioning can be seamlessly connected to each other, so that users can move freely without having to use Two sets of positioning systems. Some people may ask if it is possible to perform outdoor positioning in the street lighting device intelligent lighting positioning system, and it is no longer necessary to integrate two kinds of positioning systems. This proposal focuses on the replacement of street lights with LED lights, and the implementation is difficult. The bottleneck includes street lights that are much higher than indoor lights, and are susceptible to background light such as daylight, and the cost of construction is much higher than using GPS. , does not meet economic benefits. The smart lighting positioning system has huge business opportunities, and international companies such as South Korea Samsung have rushed to develop new applications. Samsung is now trying to build a smart lighting positioning system in the merchandiser store and install a sensor interface on the trolley. It is hoped that consumers who use the trolley can quickly find the exact location of the product to be purchased in the merchandise, saving considerable time. Physical strength and help to relieve crowds of people during peak times. However, in the mass merchandiser store to build a smart lighting positioning system, if you want to accurately locate each item, the technology still needs to be improved. Because the effective range of the intelligent lighting positioning system technology is about 2.5 meters, but the distance between the floor and the ceiling of the retail store is mostly 5 meters; how to break through the obstacles of insufficient signal strength, so that all goods can be accurately positioned, no As for the flaws, it is still a big challenge. In addition to lighting, communication, positioning, another function of intelligent lighting is applied to health care, treatment, also known as human-induced lighting, or "light therapy." In the past, the direction of lighting technology was bright. In the future, the direction is to make users feel comfortable and promote their health. For human lighting, ITRI is focusing on the treatment of mood disorders, treatment of sleep disorders, treatment of osteoporosis, etc. In the future, we hope to cut into the commercial and home markets at the same time. Treated with light, since ancient times, such as baby jaundice, sun, radiation can be cured. In the early years, people only knew it, but they did not know why. After research by scientists, it was discovered that blue light is the natural enemy of Huang Qi. At present, infants suffering from jaundice do not have to be exposed to strong light, and with appropriate amount of blue light, that is, have the same effect, and no longer need to endure the discomfort caused by strong light. Emotional disorders, sleep disorders, osteoporosis and other three diseases are known to relieve the condition through sunshine, but it is not known what kind of light is the key to treatment. The focus of research and development of the Taiwan Institute of Technology is to find out the light that can cure these three diseases through scientific methods, so as to adjust the LED lights. The biggest advantage of "light therapy" is that the treatment is the same as staying indoors, and Under the guidance of a doctor, it can be implemented at home, and the patient's acceptance is quite high. The causes of emotional disorders are very complicated, and the number of patients is increasing. In the United States, the amount of medication has jumped to the second largest number of diseases. In addition, the Nordic countries that lack sufficient sunshine for many years have a higher rate of morbidity than other countries. Philips has launched a white light bulb similar to the sun for the Nordic market, trying to offer new treatment options. In addition to promoting human-induced lighting to medical institutions, the Taiwan Industrial Research Institute is also actively researching and developing products available at home, and has penetrated the health care market from the medical market. The further extension of lighting for people is the development of differentiated lighting for the elderly and office lighting. Taking the lighting of the elderly as an example, the eyes of the elderly are less sensitive and require a brighter lighting environment. If the brightness is the same as that used by young people, it will inevitably cause inconvenience. The establishment of intelligent lighting positioning systems in medical institutions, or the implementation of human-induced lighting, can be regarded as a part of the wisdom of medical services, and is also the only way for traditional hospitals to transform into smart hospitals, with the younger and more aging. The wave is coming, it will be the fundamental way to solve the shortage of hospital manpower. International manufacturers are actively investing in the development of new applications of smart lighting. In addition to hospitals, the main battlefield will lock in schools and homes in the future. What is certain is that after several years, new applications of smart lighting will spring up and become lighting industry, ICT. A new engine for industry advancement and profitability!
