The future development trend of LED is smart bulb

Bill. Gatsby's mansion, famous for its high intelligence, has been sought after for many years, and now, at least in terms of lighting, you won't have to envy him soon. Recently, international semiconductor lighting (LED) The forum was held in Shanghai and the topic focused on intelligent lighting: since it was invented by Edison, light bulb, a commonly used household appliance, has become more and more irrelevant to the progress of the times. However, with the emergence of a series of new technologies and business models, let the light bulb be injected into the mobile Internet gene. As Liu Jianping, the relevant person in charge of Philips Lighting, said, the lights of ordinary families may soon be better than those in Gates mansion, and now they are in the early stage of a great change. The light bulb replays the story of mobile phone and TV. By sorting out the introductions made by Philips, Osram, Haier and other companies in the Forum, an industrial revolution built around the light bulb has revealed its framework, its core is to implant chips and communication modules in the bulb to make it have the characteristics of the internet of things. In this revolution, the value that lamps can provide is far from being limited to breaking the darkness. For example, in the lighting system of some European shopping malls, Wi- The light bulb of Fi chip actually becomes an indoor positioning system, which fills the deficiency that GPS signals cannot penetrate into the room. Since each light bulb has a fixed position, by talking to a smartphone, it can identify where the consumer is and design a shopping route according to the demand. Want to make a pizza? The light bulb positioning system can guide you to find flour, sausage and sauce as soon as possible. The more interesting stage of smart bulbs is still at home. Imagine that a lamp that can automatically adjust its working state according to various preset scenes will create more romance at dinner and be more sober at study, after the baby falls asleep, it will automatically adjust to a dark night light. Is this lighting experience attractive enough? And these are not just legends. Just over A week ago, LIFX, the model company of American smart light bulb, got the round financing of Sequoia Capital of 12 million dollars, which shocked the world. LIFX's bulb can fully realize the above functions. It can even play a security role. When the owner goes out, LIFX will automatically light up and extinguish according to daily habits to scare the thief. Osram's Chen Wencheng said: intelligent lighting itself has unlimited possibilities. Haier's Xiong gengchao said that the stories that happened on mobile phones and televisions in the past are also repeating the simple and clumsy non-intelligent devices in the light bulb market in just a few years, it was quickly replaced by intelligent machines combined with mobile Internet. Intelligent lighting can understand people and environment. A few years ago, it was said to ordinary people that LED may have to be explained, but now it is probably not needed. LED lights have increasingly entered the lives of ordinary people. Yan Jun, executive deputy secretary-general of the National LED Lighting Industry Alliance, said that the current LED penetration rate for home lighting is nearly 10. In fact, it is precisely because of LED that lighting has gained the opportunity to combine with mobile Internet. Wang binqiu, consulting director of LED Industry Alliance, told reporters that unlike tungsten lamp and fluorescent lamp, LED's luminous, driving and control components adopt a large number of digital technologies, and their brightness and color temperature can be controlled, this is the foundation of intelligent lighting. The past 10 years have been the beginning of LED lighting in China. Ruan Jun said that at present, the industrial scale of domestic LED has exceeded 250 billion yuan, with an average annual growth rate of 39, and the brightness under the same power consumption has also increased by nearly 6 times. The original intention of the country to develop LED is to save energy. Under the same illuminance, the power consumption of LED is about 90% lower than that of incandescent lamp. However, Ruan Jun said that the energy efficiency ratio of LED may have reached the bottleneck at present, which means that the technology-driven development model in the past 10 years is almost over and needs to be promoted in the future. The key application that can impress the market is intelligence. Chen Wencheng said that LED is born for intelligence. The intelligence he thinks is not only intelligent control, he said: In the past we controlled light, but in fact light also controlled us. A study shows that light has many non-visual effects, such as controlling emotions, issuing warnings, and regulating circadian rhythms. A European university has added some blue background light to the ceiling of the library. Tests have found that this helps to improve learning efficiency. Of course, energy conservation is still a focus of intelligent lighting. At present, 15 of the electricity consumption in the city is used for street lamps, and intelligent lighting developers are trying to make street lamps automatically reduce brightness according to traffic flow, time period, weather, etc. : real intelligent lighting can understand the environment. An open industrial ecology is needed. Some studies believe that there will be 26 billion interconnected intelligent terminals in the world in 2020, compared with 1 billion in 2009, which means there are still more than 20 times of vacancies to be filled. Haier is committed to the research and development of smart home. Xiong gengchao believes that lights may be an important entrance to smart home. In the future, in addition to the hardware of the smart lamp, many soft services will be grafted. Philips, Osram and Haier all stressed that they will provide development interfaces for intelligent lighting lamps to attract applications around Apple and Google to design APP: we need to build a developed industrial ecology. However, this industry is still in its early stage, and there are many undecided patterns. For example, what kind of language does smart light need to use to talk to smartphones, Pad, etc? There are currently 8 kinds of wireless communication protocols available. If the manufacturers say everything, then the convenience of buying a light bulb and screwing it on will no longer exist because it will not find the organization. Of course, price is also a problem. A Philips APP can be used to control the light bulb, Tmall to sell 499 yuan, and many ordinary LED bulbs have been achieved 10 yuan shipping. Of course, for electronic products, the speed of price reduction may exceed people's imagination. Ten years ago, the price of LED was dozens of times that of today.
