Data e.g. street and traffic condition information, transmission device for road traffic, has control device blanking light emitting diode according to data protocol, where data is provided in form of protocol into control device

摘要

The device has a transmitting device (2) with a light emitting diode (LED) (3) for emitting light, and a receiving device (4) with a photo diode (5) for detecting the light in a visible wavelength range. A control device (8) is provided for blanking the light emitting diode according to the data protocol. Data to be transmitted is provided in the form of data protocol into the control device.
