Problems solved by technology

[0005] At the same time, since optical wireless communication is in its infancy, there are still many technical bottlenecks that need to be overcome. For example, the time delay introduced by white LEDs doped with yellow phosphor will affect the rise and fall times of LEDs, directly affecting LEDs. The reduction of modulation bandwidth, as well as technical problems such as multipath effects

Description

technical field [0001] The invention relates to an LED lighting system with space light communication function, which belongs to the field of LED lighting and communication. Background technique [0002] Compared with existing incandescent lamps, LED has the advantages of long life, high humidity resistance, low temperature resistance, low power consumption and small size. LEDs are used for full-color displays, traffic signals, and many other means of illumination. High-efficiency blue and green LEDs based on InGaN are now commercially available. By mixing the three primary colors RGB, we can produce mixed light white LEDs. This white LED is considered to be an innovation and challenge to future lighting technology. According to Japanese international trade and industry estimates, if LEDs replace half of the incandescent and fluorescent lamps currently in use, Japan can save 60% of electricity and effectively reduce greenhouse gas emissions. In the European Union and the...
