LED visible light communication how to help counter the physical retail store

Recently, green apple bookstore of the city of San Francisco with LED lighting technology manufacturer Bridgelux (Bridgelux) and beacon indoor positioning technology developer ByteLight company, reorganized the lighting system store, let customers walked into the store feel special surprise. Light, what kind of changes in the shopping experience?

First of all, each customer enters the bookstore will receive instant welcome messages and insight of the people's preferential information, and all this is done through the LED lighting system. The company has 120 special LED lighting fixtures in the 2400 square foot store. An indoor positioning module is installed in the LED device. These modules contain a chip that can control the output of LED light, so that the LED light source emits more than 300GHz ultra high frequency flash line. The human eye can not perceive the light, but the smart phone lens can be perceived. Through the strength of the visible light signal, the software can clearly locate the location of the customer, and according to the customer's line, with light as the carrier, to push the customer's mobile phone related information. This is the current concern of scientists "visible light communication" technology.

In this technology, when the customer into the store, his position was immediately sensed, and received a welcome message. When he enters a certain area, he can receive the relevant information in the region. LED lights not only help customers precise positioning, but also as a medium for the transmission of the customer's smartphone push useful information.

In addition to the precise positioning of the precise positioning push information, green apple bookstore in the LED lighting system is also the light level, to bring customers to upgrade the lighting experience. Green apple bookstore owner, said: custom lighting experience can help us to deliver outstanding aesthetic sense, but also bring tangible economic benefits for us. "And visit the green apple store customers have said," the replacement of the LED lighting system, all kinds of book store seems to become more beautiful, cover more rich and colorful, people can not help but take a closer look at it. "

Visible light communication technology refers to the use of visible light as an information carrier, the use of fiber optic cable and other transmission media, but the direct transmission of optical signals in the air communication. LED visible light communication is visible light emitting diode than fluorescent lamp and incandescent lamp switching speed based on the characteristics of the LED with the large display, indoor and outdoor lighting equipment, signal and car taillights from the observed with the naked eye to the light wave signal to high-speed modulation of information transmission and modulation, and then use the photodiode such as photoelectric converter receiving optical carrier signal and obtain information.

LED lighting is a light-emitting diode lighting, is a semiconductor solid-state light-emitting devices. LED is made of gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and other compounds. When the electron and the hole are combined, the visible light can be radiated, and the light emitting diode can be used as a light emitting diode. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. And this is the most used metal gallium.

As an important raw material for semiconductors, gallium has been widely used in the fields of radio communication, optical fiber communication, automotive radar, LED lighting, solar cell and so on. For Japan and South Korea, both in manufacturing and electronics, the importance of gallium is self-evident. As one of the advantages of China's resources, the purchase and storage of gallium has also been concerned about the government and non-governmental organizations, such as the Pan Asian non-ferrous metals exchange. Since its establishment in 2011, the Pan Asian non-ferrous metals exchange will be listed as one of the listed species, and through its own platform advantages, with the strength of private capital to participate in the purchase and storage of gallium.

Now, the development trend of the strong impact of e-commerce worldwide, in 2013, Chinese e-commerce transactions exceeded 10 trillion yuan, an increase of 26.8%, of which retail sales network of more than 1 trillion and 850 billion yuan, an increase of 41.2% (according to the Ministry of Commerce Chinese e-commerce report "(2013)"). Retail stores, including department stores, shopping centers, shopping malls, supermarkets, etc., are trying to seek the hands of e-commerce from the hands of customers to recover the panacea.

The United States Green Apple store in the Amazon e-book and dominate the market situation, a new ", through the visible light communication" lighting system to provide a more comfortable and more personalized shopping experience, adding new vitality to the bookstore, this is also the "visible light communication technology to advance the practical application in. In the future, with the continuous innovation of the LED lighting industry, new applications continue to emerge, the potential demand for gallium metal can not be ignored.
