Abstract
The invention provides a system of generation of multi-channel analog output signals, from a single analog input signal, and the controlled activation of peripheral devices responsive to the multi-channel analog output signals. A single-channel to multi-channel analog-to-analog converter is provided to convert the single analog input signal to multiple output channels. Uni-directional coupling is used for coupling and mixing the multi-channel outputs and transferring the mixed outputs to a data bus. Signals on the data bus are used to drive the multiple peripheral devices.
Claims35
Lighting apparatus comprising:
- an analog input;
- a plurality of driving circuits each capable of driving a light source;
- a control circuit configured to provide a plurality of analog output signals in response to an analog input signal presented at the analog input, the control circuit embodying a plurality of mappings, each of the mappings relating values of one of the analog output signals to values of the analog input signal presented at the analog input;
- wherein each of the plurality of driving circuits is connected to be controlled by one of the analog output signals;
- wherein the mappings are such that, for each of the analog output signals, changing the value of the analog input signal within a range causes the analog output signal to vary according to a profile specified by the one of the plurality of mappings associated with the analog output signal.
