Description

Technical Field [0001] The present invention relates to a traffic signal assistance alarm device using a laser,

The present invention relates to a traffic signal assistance notification device using a laser, and more particularly, to a traffic signal assistance notification device using a laser, in which a vehicle driver stops when a traffic signal is stopped even in an environment where the driver ' To a traffic signal assisted notification device using a laser.

Traffic lights are usually installed on pedestrian crossings so that pedestrians and vehicles can use the roads together. The traffic lights stop the progress of the vehicle entering the pedestrian crossing and allow pedestrians to pass.

However, crosswalks and traffic lights that are currently being used are insufficient in pedestrian protection in areas where frequent nighttime or mist is present, and in particular, in the case of roads where the vehicle is not frequent, there are not many pedestrians who normally go to the crosswalk. Ignored cases frequently occurred.

In order to protect the night pedestrian passing through the crosswalk, a light is provided on the crosswalk to secure the view of the driver of the vehicle entering the crosswalk. However, in the fog area, it is difficult to secure visibility even during the daytime.

In spite of the driver's attention, if fog occurs, the visual field width and visual distance are short, making it difficult to secure a safe distance from the front car regardless of the driver's intention. Especially, Time is running out. As a result, traffic accidents with pedestrians crossing the pedestrian crossing are frequently occurring in fog areas due to accidental contact with the vehicle ahead.

Even if the performance of the headlight is excellent, it is very dangerous for the driver of the vehicle because the water particle reflects the light and obstructs the field of vision. Although the fog lights are used in such cases, the fog lights are more transparent than the headlights, and the angle of view is wide, so that the front view is advantageous. However, the driver's visibility is still short because the light is illuminated at a short distance. Therefore, it is difficult to expect a great effect in confirming the traffic signal.

In order to solve these problems, there have been proposed techniques for providing a driver's alertness so that the stop line of the crosswalk can be seen as a wall using a laser. However, the laser beam has a disadvantage in that it is not useful in an environment where the width is narrow and the fog is not generated, and the visibility is low in the environment where the fog is not generated.

In addition, the first strut 10 may be installed in the second delivery 9 and the second post 20 may be installed in the first delivery 7.

The laser emitting unit 30 is installed in the inner space of the first strut 10 and irradiates the laser beam L of a predetermined color toward the second strut 20. Generally, a laser beam (laser beam) has three major characteristics. First, the laser beam emits monochromatic light, ie, a single wavelength of light. Second, the laser beam is highly coherent with neighboring atoms having closely related relations. Third, the laser beam has good directivity (or straightness). Because of this, the laser beam does not spread but goes very far in parallel with the slender light. Since the intensity of light is not reduced even if the distance is long, the laser beam is used in equipment for measuring distance, position, and the like. The traffic signal assistant alerting device 1 according to the present invention uses this characteristic of the laser, and the laser beam L moves farther away from the LED or LED in a short viewing distance of the fog, It has the advantage of being able to. The laser beam (L) is a green laser having a single wavelength in the range of 530 nm to 555 nm which is good in visibility. The laser emitting unit 30 is operated in conjunction with the traffic signal lamp T by a control unit 60 to be described later.

Of course, the control unit 60 may be adapted to irradiate the laser beam from the laser emitting unit 30 until the red light is turned off from the blinking of the yellow light among the traffic lights.

The laser beam L transmitted through the fifth mirror is transmitted to the first and second columns 10 and 20 by the first to fourth mirrors 41 to 43 of the laser beam fence forming unit 40 20. The laser beam L reflected by the fourth mirror 47 is absorbed through the light absorbing portion 49. The fence shape of the laser beam formed by the laser beam fence forming unit 40 between the first strut 10 and the second strut 20 in a situation where a mist is generated around the crosswalk and the visual distance is short, It can be recognized from afar. Therefore, the vehicle driver can stop the vehicle driving through the fence formed by the laser beam even when the traffic light (T) is not visible from a distance due to fog.

The laser beam L from the laser emitting portion 30 toward the second support 20 is reflected by the first spot forming mirror 52 through the fifth mirror 51 and is reflected by the fifth mirror 51, And is transmitted to the second spot forming mirror 54 by the first mirror 41 provided in the second column 20.
