Abstract

PURPOSE:To secure the traffic safety of automobile by displaying the braking of an automobile backward of a car body to call the attention of a following car and make the existence of an automobile clear and soften the dazzling at the time of lighting a high-mounted stop lamp and quicken the preparation for braking of a following car during the traveling at night and in the case of emergency stop. CONSTITUTION:During the operation of a brake, after lighting all of light emitting diodes 1 of a high-mounted stop lamp 2 for a constant time, the light of the light emitting diodes 1 in series or in parallel with each other are put out per a unit from the end or intermittently. Or, all of the light emitting diodes 1 in series or in parallel with each other are lighted for a some seconds, and thereafter, the voltage is lowered to lower the luminous intensity of the whole of the high-mounted stop lamp to about 30cd. The high-mounted stop lamp 2 is thereby lighted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high mounted stop lamp lighting system having an auxiliary role of a stop lamp for preventing rear-end collision of a rear vehicle by displaying the braking of the vehicle on the rear side of the vehicle body. However, when the vehicle is mounted on the rear part of the car in an easy-to-see place and the car running at night recognizes an obstacle ahead or stops suddenly, the car is braked by a brake to call attention to the following car. In addition to clarifying its existence, it softens the glare that is felt when the high-mounted stop lamp is lit, promotes braking preparation for the following vehicle, and ensures the traffic safety of the vehicle.

2. Description of the Related Art High-mounted stop lamps have been obliged to be mounted on automobiles in the United States from around 1985 in order to assist the stop lamps. There is a risk of dazzling, and when driving a car, it was necessary to operate it without extra dazzling to the driver of the following vehicle in order to ensure safety.

It is necessary to be able to confirm the lighting from a distance of 100 meters behind in the daytime, and therefore many efforts have been made to increase the brightness.

However, the lighting is often lost due to continued overheating, which neglects the attention of the following vehicle and is very dangerous.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a high-mounted stop lamp having a light emitting diode as a light source is wired in a lighting mode control circuit to control a lighting mode, and a certain amount of time is maintained while a brake is depressed. After turning on the lamp for all hours, turn off the light emitting diodes in series or in parallel from the end for each unit or intermittently, or turn on all the light emitting diodes in series or in parallel for several seconds, and then lower the voltage to reduce the entire lamp. The light intensity of the car is lowered to about 30 cd, and when a car running at night recognizes an obstacle ahead or stops suddenly, the car is braked by a brake to alert the following car and the existence of the car is clarified. And soften the glare that is felt when the high-mounted stop lamp is lit, and encourage braking preparations for the following vehicles. It is intended to ensure the passing safety.

[0006]

The present invention provides a high mounted stop lamp 2 having a light emitting diode 1 as a light source.
To the lighting mode control circuit to control the lighting mode,
While the brake is stepped on, after all the high-mounted stop lamps 2 are turned on for a certain period of time, the series or parallel light emitting diodes 1 are turned off from the end in units a, b, c, or intermittently, Alternatively, it is a lighting system of a high mounted stop lamp in which all the light emitting diodes 1 connected in series or in parallel are lit for several seconds, and then the voltage is lowered to lower the luminous intensity of the entire high mounted stop lamp 2 to about 30 cd.

[0007]

[Operation] The contents of the present invention will be described in detail with reference to the drawings. A high-mounted stop lamp 2 having a light-emitting diode 1 as a light source is wired to a lighting mode control circuit to control a lighting mode, and while a brake is applied. After all the high-mounted stop lamps 2 are turned on for a certain period of time, the series or parallel light emitting diodes 1 are turned off from the end for each of the units a, b and c, or intermittently turned off, or the series or parallel light is emitted. The diode 1 is fully lit for a few seconds, and then the voltage is lowered to reduce the luminous intensity of the entire high-mounted stop lamp 2 to about 30 cd. Is.

Since the high mounted stop lamp 2 may dazzle the driver of the following vehicle when the luminance ratio is increased, the light source is a light emitting diode in the present invention, so the high mounted stop lamp 2 is fully lit for several seconds. Then, the unit a is turned off as shown in FIG. Further, as shown in FIG. 3, the units b and c are turned off. Then, the luminous intensity is lowered to the range of 30 cd while leaving the central portion 3. Therefore, as shown in FIG. 5, the luminous intensity is 30 cd while maintaining the afterglow on the way.
It goes down to the range of.

Further, since the light source is a light emitting diode, all the lights are turned on for a few seconds, and then, as shown in FIG. 4, every other light emitting diode 1 is turned on and every other one is turned off.
Therefore, the luminous intensity falls to the range of 30 cd. That is, as shown in FIG. 5, the luminous intensity decreases to the range of 30 cd while maintaining the afterglow on the way.

Further, since the light source is a light emitting diode, as shown in FIG. 1, the light is fully turned on for several seconds, and the light intensity of the entire high-mounted stop lamp 2 is lowered to the range of 30 cd in order to lower the voltage. That is, as shown in FIG. 5, the luminous intensity decreases to the range of 30 cd while maintaining the afterglow on the way.

[0011]

The present invention is configured as described above, that is, the high-mounted stop lamp 2 having the light-emitting diode 1 as a light source is wired to the lighting mode control circuit to control the lighting mode and while the brake is applied. After turning on all the high mounted stop lamps 2 for a certain period of time,
The series or parallel light emitting diode 1 is turned off from the end for each unit a, b, c, or intermittently, or the series or parallel light emitting diode 1 is fully turned on for several seconds, and then the voltage is lowered to be high mounted. Since the lighting system of the high-mounted stop lamp is designed to reduce the luminous intensity of the entire stop lamp 2 to about 30 cd, the luminous intensity can be reduced to 30 cd, and care is taken not to dazzle the driver of the following vehicle. As a result, it is possible to promptly alert the following vehicle, prevent the lack of lighting, and prevent the rear-end collision of the following vehicle during night driving.

Since the high mounted stop lamp 2 needs to be able to confirm the lighting from a distance of 100 meters behind in the daytime, it is necessary to make an effort to increase the brightness. However, if the light source bulb is strong, it is overheated. In many cases, the lighting was lost due to the continuation of the vehicle, and the attention of the following vehicle was neglected, which was very dangerous.
Since a light emitting diode is used as the light source, these drawbacks have been resolved. In addition, in order to reduce the glare felt when the high-mounted stop lamp 2 is lit and to improve the visibility of the following vehicles when the high-mounted stop lamp 2 is lit, first turn all lights on at the initial stage of lighting, and then set the brightness up to 30 cd. Because it is down, it is now possible to drive safely and comfortably in driving a car.
