| 摘要 |
The invention concerns an electrical appliance in particular a car radio, wherein are provided several components (12, 14, 16, 18,20) communication with one another, at least two of said components communicating with each other by means of light signals. The light signal transmission can be operated, for addressing specific components, by beam, i.e. by light diffused by radiation in a beam or by optical fibres (26), or, for accessing all the components, on a common channel by wavelength division multiplex or still by any other known addressing and accessing process in communications technique. |
