Japanese take advantage of the LED lights to communicate underwater

28.08.2013.

Previously want to talk underwater, we mostly use the ultrasound to send dialogue, but this method is very expensive. Divers are generally expressed in gestures, but which only can pass a simple meaning, moreover for the beginners, they may not remember clearly, they would be confused in the crisis and affect communication.

In order to solve the problem of underwater communication, with the help of the LED lights Okinawa, Japan, researchers have developed a set of system, which is used to transmit voice. The Principle is that the sound waves is converted into the LED lights, and then emit to the sensor received by the other and then the light is turn into the sound waves. If the light is blocked, leaving only noise.

The researchers said that the system can only communicate in one meter range at the early stage of development,. But then they took into account the volume, transmission speed, sound, and the diving depth and other factors, finally broaden the scope of application of the system.

Currently, even the distance between the two divers is 30 meters, this underwater communication tools still can be used, either at a depth of 30 meters underwater to communicate. Fully charged, then it can be used for four hours, the system can not only be used underwater, there is no problem that those who are on the shore talk with the divers underwater.

The researchers said that the current system is of large volume, they will be committed to developing a smaller mask to facilitate people to use in different industries.

There is no doubt that LED lighting technology as the third generation of the semiconductor applications also can be perfectly combined with the communication.Nowadays,the LED flood light and LED tube light is most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light so that fully guaranteed stabe and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection ,login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.
