Abstract:
1. An infrared ray IR switching device adapted for an apparatus, the IR switching device electrically connected to an apparatus, comprising: an IR transmitter for emitting an IR signal with an emission power, wherein the emission power is adjustable; an IR receiver for receiving a reflected IR signal to generate a response signal, wherein the reflected IR signal is generated after the IR signal is reflected and the response signal comprises a first signal as the IR receiver receives the reflected IR signal while the response signal comprises a second signal as the IR receiver does not receives the reflected IR signal; a processor for processing the response signal and for generating a processing signal after processing the response signal; and a controller for switching the apparatus according to the processing signal; wherein the apparatus is switched on when the IR receiver generates the response signal comprising the first signal and the second signal: the apparatus is switched off when the IR receiver generates the response signal comprising the first signal and the second signal again.
