METHOD AND APPARATUS FOR DIMMING WITH RATE CONTROL FOR VISIBLE LIGHT COMMUNICATIONS (VLC)

摘要

A visible light communication, VLC, device and a method performed by a VLC device for lighting and data transmission is provided. A first stream of bits is received and a first switchpoint for transmitting the first stream of bits and first filler data is determined, wherein the first filler data is based on a brightness level, and The first stream of bits and the first filler data are transmitted, by red green and blue, RGB, light emitting diodes, LEDs, wherein the first filler data begins to be transmitted at the first switchpoint. A second stream of bits is received, wherein the second stream of bits is different than the first stream of bits, and a second switchpoint for transmitting the second stream of bits and second filler data is determined, wherein the second filler data is based on the brightness level. The second stream of bits and the second filler data are transmitted, by the RGB LEDs, wherein the second filler data begins to be transmitted at the second switchpoint, wherein a naked eye of a human cannot detect flicker of the VLC device.
