Abstract:
An example of a power and modulation circuit utilizes a very high frequency switching power converter to supply drive current power to cause a solid state light source to emit light. The power converter is configured to convert power from a power source to direct current to supply via the output to the light source, at least in part by a switching function of the power converter at a very high frequency rate. The circuit, in such an example, also includes a control circuit coupled to be responsive to input data and control operation of the power converter so that the current output to drive the light source modulates the light emitted from the light source to also carry the input data.
