Visible Light Communication and Smart Lighting and Their Industrialization

1. Market and Technical Pain Points

Modern wireless communication, after hundreds of years of research, has brought great convenience to modern life, but still faces some unresolved challenges, such as: restricted zones for underwater wireless communication, severe co-channel electromagnetic interference in complex industrial environments, and the vulnerability of wireless communication to eavesdropping and localization.

2. Application Prospects of Visible Light Communication Technology

Currently, China's intelligent visible light communication lighting market is in its nascent stage, with continuously growing market demand. In the military sector, there are no domestically developed, controllable, or mature commercial products available to supply the military; both the United States and the United Kingdom have specialized companies operating in this field. The industrial sector is monopolized by Japan's Hokuyo and Germany's Pepperl+Fuchs. In the civilian sector, companies such as Philips and Cree lead industry development. In the realm of smart lighting, China's new infrastructure market is enormous.

• Compared to Wi-Fi, LiFi has significantly reduced anti-interference and penetration capabilities. If the light path between the transmitter and receiver is blocked, data transmission stops immediately, let alone penetrating walls.

• Visible light is not suitable for bidirectional information transmission, as it is difficult to transmit return signals. If reverse signals are to be transmitted over the network, each lamp must be connected to a network cable. For signal return, the receiving device must also be equipped with a light bulb, and precise alignment is required; otherwise, the speed will not increase. Therefore, unidirectional transmission is more suitable for Li-Fi, applying visible light technology in scenarios where information return is not required.

• Due to the lack of relatively mature chips, the equipment used by researchers in the Fudan Laboratory is as large as two laptops. To miniaturize the equipment, the chips must be shrunk, which requires financial support for chip technology R&D.

Advantages of Infrared Light Transmission:

• Strong directionality, allowing interference to be avoided by controlling the direction;
• Short transmission distance avoids complex routing and conflicts;
• All-weather transmission, resistant to rain, snow, fog, etc.

2. Subsea Optical Communication Base Station

• provides communication coverage for underwater operations;
  

• Diving entertainment provides safety assurance;

• Underwater scientific research base station, underwater sensor network.

3. Technological Innovation

• proposes a subwavelength ideal LED model;

• has successfully developed a subwavelength vertical structure LED with a thickness of 225nm and an emission wavelength of 411nm;

• The new LED structure improves luminous efficacy, reduces junction capacitance, lowers LED heat generation, and extends the LED's 3dB bandwidth;

• Underwater visible light communication system, first equipped with this LED to verify 60Mbps high-speed communication in a 10-meter water tank.
