Patent ID: 7639126

Claim:
An apparatus for lighting a brake lamp for a vehicle using a non-contacting switch, the apparatus comprising: a brake pedal arm including a brake pedal at one end thereof; a pedal arm stop bracket integrally formed on the brake pedal arm at the upper side of the brake pedal arm; and a high-frequency type non-contacting switch that is separated from or comes in contact with the pedal arm stop bracket so as to be turned on or off depending on the operation of the brake pedal, wherein the non-contacting switch is a proximity sensor, and wherein the high-frequency type non-contacting switch includes: an electromagnetic coil generating a high frequency magnetic field depending on the operation of the brake pedal, after power is applied from a battery; an oscillation circuit oscillated in a predetermined frequency band due to the magnetic field generated by the electromagnetic coil; a detector circuit detecting the change of the magnetic field caused by the oscillation of the oscillation circuit; an integration circuit converting the change of the magnetic field detected by the detector circuit into a current signal; an amplifying circuit amplifying the current signal converted by the integration circuit; a signal output unit outputting the signal amplified by the amplifying circuit; and a connector through which the signal output from the signal output unit is transmitted to a brake lamp and an ECU of a vehicle.
