KR20170127113A - video traffic light on road with laser light source - Google Patents

Abstract

The present invention relates to technology related to a laser light source using a signal which is directly projected onto the ground in order to complement the visibility of an existing traffic light and distinguish vehicle lines on the intersection at night. The present invention can give a discernible signal at night by permeating a dynamic animation to the ground surface of a road by using a laser in a current traffic light. Prior inventions for a traffic light using a laser are required to install equipment for laser emitting and blocking devices in a predetermined part of a road. The present invention does not need to install additional installations on a road or a sidewalk as shown on [drawing 1] by using a top-down laser emitting method shooting a laser from the top to bottom by using a traffic light or a lighting device which is installed already. Moreover, the present invention protects the view of a driver and can be used by emitting a laser behind a proceeding direction by making the view of the driver coincide with the direction of the laser. A system of the present invention: includes a step of transmitting a dynamic image on the ground in a road ground projection dynamic traffic light using a laser light source; and provides an auxiliary image of signal transmission.

Description

Technical Field [0001] The present invention relates to a dynamic light source,

The present invention relates to a signal generator using a dynamic laser, and more particularly, to a signal generator using a dynamic laser for generating an animation effect on a road surface using a laser at night intersection and generating a signal in parallel with a conventional signal will be.

Generally, a traffic light is installed at an intersection so that a pedestrian and a vehicle can use the road together. The traffic light controls the progress of the straight-ahead / left-turn vehicle and allows pedestrians to cross the intersection.

Another technique for protecting pedestrians in a crosswalk is to use a laser to make the stop line of a crosswalk look like a wall, thereby providing a driver's alertness.

According to an aspect of the present invention, there is provided an apparatus for generating an intersection signal using a laser, comprising: a signal input unit for receiving a signal change of a signal lamp installed at an intersection; A control unit for receiving and analyzing a signal of the signal input unit and controlling the laser to be sprayed on the road surface according to the signal; And a laser launching unit configured to be in the same direction as the driver's field of vision according to the control signal of the control unit and to emit a dynamic laser beam in each lane behind the vehicle traveling direction.

According to the present invention, while it is difficult to visually recognize a signal by equalizing a traffic light at night, a laser transmits an accurate signal to a driver with laser light of a different color according to green, yellow, and red to the driver, and a straight lane and a left turn lane And informs the driver of the maintenance and change of the lane accurately.
