Method and apparatus for dimming with rate control for visible light communications (VLC)
A visible light communication (VLC) device for lighting and data transmission includes a dimming block and a light emitting device. The dimming block is configured to receive a desired brightness level, determine a data duty cycle for the data transmission based on the desired brightness level, determine a filler luminance value based on the desired brightness level, and generate dimming information for use by a second VLC device for decoding the data. The light emitting device is configured to convert the data, the filler luminance value, and the dimming information to visible light for transmission to the second VLC device.
