Hereinafter, the present invention will be described in detail to enable those skilled in the art to easily understand and reproduce the present invention.

1 is a block diagram of a vehicle lamp failure safety providing apparatus according to an embodiment of the present invention.

As illustrated, the vehicle lamp failure safety providing apparatus includes a battery 100, a vehicle lamp 200, a switching unit 300, and a controller 400. The battery 100 is a component for supplying power to the vehicle as a whole. The vehicle lamp 200 is a lighting means exposed to the outside of the vehicle, and includes a headlamp lamp 210, a headlight lamp 220, a taillight 230, a turn signal 240, and a brake lamp 250 as shown. can do. The switching unit 300 is a configuration for supplying the vehicle battery 100 to the vehicle lamp 200, the headlamp lamp 210, the headlight lamp 220, the taillight 230, the turn signal 240 and the brake lamp The plurality of switches 310, 320, 330, 340, and 350 correspond to the one-to-one correspondence with the 250. Each of the switches 310, 320, 330, 340, and 350 is switched to the first terminal (terminal A) or the second terminal (terminal B) according to the switching control signal. The controller 400 is a controller for controlling the switching unit 300 to provide vehicle lamp failure safety.

First, the A terminal and the B terminal side checks the voltage value at both ends and transfers it to the controller 400. The controller 400 receives a voltage value transmitted from the A terminal and the B terminal side, and determines whether the voltage value is within a preset reference operating voltage range. As a result of the determination, if any one of the voltage values transmitted from the A terminal and the B terminal side is out of the reference operating voltage range, the controller 400 transmits an error message to the status display output unit 500. The status display output unit 500 receives the error message and outputs it to the outside. Here, the status display output unit 500 may be a display means such as a liquid crystal display (LCD) or a light emitting diode (LED), or may be a speaker for audio output. In addition, the controller 400 determines which of the terminals A and B is out of the reference operating voltage range. When the determination result is the A terminal, the controller 400 controls the switching unit 300 to switch to the B terminal. If the determination result is the B terminal, the controller 400 controls the switching unit 300 to switch to the A terminal.
