LED communication is expected to be 10,000 times the bandwidth of wifi after 4 years.

Recently, some lighting experts said at the industry exchange conference that LED visible light communication can be promoted and applied in 2018. Speakers are optimistic about the domestic market prospects of LED.

China is the fastest growth of the LED market <br> <br> at the conference, OSRAM Lighting Co., Ltd. Semiconductor Division Senior Technical Manager Chen Wencheng analysts said, thanks to the LED costs drop faster than other light sources, LED market penetration The rate is increasing rapidly. “By 2020, LED market penetration will reach 70%, and mainland China and Taiwan are the fastest growing markets.”

LED communication is expected to be promoted four years later. "Visible light communication is an emerging optical wireless communication technology that modulates signals onto LED visible light for transmission." Experts said at the meeting. He believes that LED can not only be used in the field of lighting, but also can be cross-integrated through the communications industry and the Internet of Things.

Visible light communication technology (VLC) refers to a communication method that uses light in the visible light band as an information carrier, does not use a transmission medium such as a fiber channel, and directly transmits optical signals in the air, and has high safety performance and energy saving in short-distance communication. With a wide range of applications, the bandwidth is 10,000 times that of wifi and 100 times that of 4G. For example, to achieve theoretical speed, it takes only 0.1 second to download a 1G movie.

15A 125V GFCI Receptacle with LED light indicator does not protect against circuit overload, short circuits, or shocks. For example, you can still be shocked if you touch bare wires while standing on a non-coducting surface such as a wood floor.

Automatic fault alarm, if GFCI malfunction, the LED will flash, the power will be cut off.
