Abstract

PURPOSE:To prevent previously a rear-end collision accident by constituting a circuit in such a way that rear brake lights are lit in correspondence to the OFF-state of a detecting switch in an ON/OFF operation of an accelerator pedal, so that the control operation of a preceding automobile can be quickly notified to the driver of a following automobile. CONSTITUTION:It is so arranged that when an accelerator pedal 4 is treaded down, the movable contact 3a of a switch 3 is disconnected from a fixed contact 3b, and when the accelerator pedal 4 is not operated, the movable contact 3a of the switch 3 is brought into contact with the fixed contact 3b to be closed. Accordingly, brake lamps are lit at the some time as a foot is removed from the accelerator pedal 4, and from this point of time engine brake starts to work. consequently, comparing with the case where the brake lamps are lit from the point of time when the brake pedal is treated down, the driver of a following automobile can quickly notice the braking of a preceding automobile, and the accidents such as a rear-end collision or the like can be previousuly prevented.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a lighting device for a brake light of an automobile.

(Prior Art) A conventional brake light lighting device for an automobile has a configuration in which the brake light is turned on when the driver operates the brake pedal. However, according to this conventional device, when a large number of cars are running in a row on a highway etc., the driver of the car in front depresses the brake pedal and the brake lights turn on, and then the driver of the car behind turns on. If the driver operated the brakes after seeing the brake lights on, the car following would not be able to brake in time.
This may cause a rear-end collision.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned points, and provides a brake light configured to promptly notify the driver of a following vehicle of the braking operation of the preceding vehicle. The present invention aims to provide a lighting device.

(Means for Solving the Problem) The present invention includes a switch that detects whether the accelerator pedal of an automobile is on or off, and a circuit that turns on a brake light at the rear of the automobile when the switch is in a state corresponding to the off state of the accelerator pedal. It is characterized by having the following.

(Example) Fig. 1 and MIJ Fig. 2 show an embodiment of the brake light lighting device of the present invention. 3 is a switch provided according to the present invention, and as shown in FIG. 2, when the accelerator pedal 4 is depressed (on) as shown by the two-dot chain line, the movable contact 3a of the switch 3 that moves together with the accelerator pedal 4 is turned on. The movable contact 3a of the switch 3 is separated from the fixed contact 3b and is closed when the switch 3 is not operated, as shown by the solid line, and comes into contact with the fixed contact 3b.

In this brake light lighting device, since an accelerator pedal and a brake pedal are installed side by side in a car, when a driver performs a braking operation, he or she first releases the accelerator pedal 4 and then depresses the brake pedal. As shown in FIG. 1, when the driver takes his foot off the accelerator pedal 4, the switch 3 closes and the brake light 1 turns on. In other words, the brake light 1 lights up from the time when the accelerator pedal is turned off before the brake pedal is depressed, and the engine brake is applied from the time when the accelerator pedal is turned off, so when the brake light 1 is turned on from the time when the brake pedal is depressed, as in the conventional case. Compared to this, the driver of the following car can quickly learn about the braking of the preceding car, and can prevent accidents such as rear-end collisions.

FIG. 3 shows another embodiment of the present invention, in which the circuit of FIG.
By providing a switch 5 that opens when the vehicle is stopped, the brake light 1 is kept from lighting when the vehicle is stopped. In this embodiment, this switch 5
The speed signal 6 is used as a means for operating the speed signal 6.
The control circuit 7 is configured to open the switch 5 when the vehicle indicates zero speed, and close the switch 5 when the signal indicates that the vehicle is running. According to this configuration,
Battery consumption can be prevented when the vehicle is stopped with the key switch 2 turned on for a long time.

(Effects of the Invention) As described above, the present invention includes a switch that detects on/off of the accelerator pedal of an automobile, and a switch that turns on a brake light at the rear of the automobile when the switch is in a state corresponding to the off state of the accelerator pedal. Since a circuit is provided, the driver of the following vehicle can quickly learn the braking operation of the preceding vehicle, and can prevent accidents such as rear-end collisions.
