Nobel Prize winner LiFi will be a killer application of 100 million light crystal electric grab

Recently, Nobel prize winner in 2014, the second prize in physics, Nakamura Shu, he predicted that the next killer LED industry applications in optical communications (LiFi). The lights of the future home will be able to carry the signal to become the last mile of data transmission. Or you can download movies and music under the street light. Taiwan LED manufacturers including EPISTAR, Everlight, Lite has been in the development of technology, no problem, just waiting for the market to mature.

Home LED lamp can carry signal

LED industry legend Nakamura Shuji (Nakamura Shuji) last year, won the Nobel prize, is he found blue plus yellow phosphor, greatly enhance the formation of brightness white light, a change in the past LED can emit red light and weak green dilemma, also let the application scope of LED is open.

The earliest LED due to lack of blue light and brightness is too low, can only be used in the low price of home appliances dashboard, mobile phone keypad backlight. After the discovery of blue light, the LED industry has 2 huge wave of growth, the first is the backlight, the application of pen, television, mobile phones. Peak in 2010, Taiwan LED plant revenue, profit in the year hit a new high. Followed by lighting, led by CREE, PHILPS in the past 2 years, has introduced a lower price, better light effect LED lighting products, replacing Edison in more than 100 years ago invented the incandescent bulb.

Currently LED TV penetration rate of up to 100%, backlight market tends to mature. Lighting market because of the need for time to change the light, stable and slow growth, no explosive theme. In the lack of obvious momentum in the 2 applications, the domestic LED factory stock prices recently lying on the ground.

Where is the next hope for the LED industry? Perhaps based on the consideration of trade secrets, crystal chairman Li Bingjie in last month's 2015 LED Taiwan process exhibition, the global LED industry, said: I am also thinking. "But last week, Nakamura Shuji, who was invited to Taiwan by the University of communications, gave the answer.

Nakamura said: LED next killer application is optical communications (LiFi). The existing mode of communication, fiber optic cable communication with microwave wireless communications (such as WiFi), but the 2 major drawbacks of WiFi is vulnerable to interception, microwave harmful to the human body.

With LED light as the carrier signals, you do not have these problems, as long as the signal is blocked, the light is blocked, the naked eye can perceive immediately, more security. In addition, LED light does not microwave, does not harm the human body, it will not interfere with the instrument, currently in hospitals, aircraft and other conditions of the engine room is higher, have been used.

Although the application of LED optical communication is still in the early stages of development, however, the industry said that the future if the popularity, as long as there is light, there is a signal. For example, open the table lamp, can download video. Standing under the street lamp can check the map on the Internet; in the supermarket shelves, but also through the light to send different product information to consumers. Even under the surface of the ocean, as long as the light can be transmitted signal.

At present, Taiwan factory including EPISTAR, Everlight, Lite, the new century, all existing solutions or working on LED optical communication, be prepared to meet the new market, eager for a fight, will end mature consumer applications.
