Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to taillights for automobiles. In recent years, with the development of expressway networks, rear-end collisions on expressways have become more important. This is thought to be due to the fact that at night, the driver of a car following the car in front fixes his or her viewpoint on the taillight of the car in front, causing a hypnotic effect and losing the sense of distance from the car in front. It was getting worse.

The present invention has been made in view of the above-mentioned points, and a plurality of light fixtures are arranged next to each other to form a single tail light, and one of the plurality of light fixtures is randomly selected and set at a certain time. By turning on the taillight, then randomly selecting the same or another light and repeating these actions, the point of view of the driver of the following vehicle is shifted by randomly changing the location of the taillight that lights up. This provides a taillight for a car that prevents hypnotic effects and prevents the user from losing the sense of distance from the vehicle in front.

The details of the present invention will be explained below with reference to _the embodiment _shown in _FIGS . It was the taillight of a car.

1 is a random number generator which randomly generates only one of nine numbers from 1 to 9 at regular intervals, and sends a signal to a decoder 2 which decodes the generated number. The decoder 2 is the random number generator 1
It receives the signal, decodes the numerical value, and outputs the signal only to the output terminal T (t ₁ , t _{2 .} . . t ₉ ) corresponding to the numerical value.

H (h ₁ , h ₂ ... h ₉ ) is the output terminal T (t ₁ , t ₂ ...
... _t9 ) and is operated by the signal output from the decoder 2. Once the signal is received, the holding circuit is connected to each of the random number generators 1 and 9) and is operated by the signal output from the decoder 2. It is designed to act as a retainer. D (d ₁ , d ₂ , ... d ₉ ) is a drive circuit that turns ON upon receiving the signal held by the holding circuit H, and energizes the corresponding lamp lx so that the lamp lx lights up. It's getting old.

Therefore, the lighting time of the lamp lxX is the same as the time during which the signal is held in the holding circuit H.

3 is a switch that turns the taillight L on and off, and is connected in series with the power source 4, and also operates the random number generator.
It is circuited to turn on and off.

To explain the operation of the structure of the present invention as described above, when the switch 3 is turned on to turn on the taillight L, the random number generator 1 connected to the switch 3 is activated and any one of 1 to 9 is activated. A numerical value is generated at random and sent to the decoder 2.
The decoder 2 decodes the numerical value and sends a signal only to the output terminal Tx corresponding to this numerical value.
A holding circuit Hx connected to Tx holds the same signal until the next random number is generated. Meanwhile, drive circuit Dx
Turn on the light fixture connected to this drive circuit Dx at this time.
Only lx will turn on. Next, the random number generator operates again and randomly generates any one of the numbers 1 to 9 as before. At the same time, the holding circuit Hx, which had been operating up until now, turns OFF, and the lamp lx goes out. As described above, the decoder 2 decodes this generated numerical value and sends a signal only to the output terminal Ty corresponding to this numerical value, and the holding circuit Hy connected to the output terminal Ty generates the next random number from the same signal. hold until During this time, the drive circuit Dy is turned on, and at this time, only the lamp ly connected to this drive circuit Dy lights up.
Thereafter, the lights lz, lα, and lβ start blinking in the same way repeatedly, and the parts of the taillight L that are illuminated are changed one after another.

As described above, according to the automobile taillight according to the present invention, it is possible to randomly change the illuminated part of one taillight, and by moving the viewpoint of the driver of the following vehicle, the hypnotic effect on the driver can be prevented. It is an excellent device for ensuring safety when the vehicle is running, as it prevents rear-end collisions without causing a loss of distance between the vehicle and the vehicle.
