| 20110159918 | ANTI-BLINDING DEVICE HAVING WIRELESS COMMUNICATION FUNCTION - Disclosed is an anti-blinding device having a wireless communication function to allow a user to conveniently use a wireless communication cellular phone during operation. The anti-blinding device includes a main control device, a light transmission control device, first and second receiving/transmitting unit to perform signal conversion and transmission between a cellular phone and the main control device, and voice input and output devices. The main control device outputs alarm light and a ringtone using a lamp and the voice output device if it is determined that a digital signal transmitted from the second receiving/transmitting unit is an incoming call signal, and if the digital signal is a voice signal, transmits the digital voice signal to the voice output device.
