In order to ensure the safety when people crossing the street, a new LED light line with warning system is invented.
With the help of Light Line, a warning light installed in the pavement, crossing the road becomes safer for pedestrians. Working in parallel to the switch function for the standard traffic light, Light Line uses a red or green signal to show when the street can be crossed safely and without danger. This new warning light was developed by DSTA, a Spanish company that designs and manufactures LED solutions for traffic lighting and transports. The various colors in the signal light are provided by light emitting diodes from Osram Opto Semiconductors.
Pedestrians often step onto a road crossing when the traffic light has already switched to red, particularly during less busy traffic periods. This does not always have a happy ending. To reduce the resulting number of accidents, DSTA, the Spanish producer of light systems, has developed a solution with Light Line. In addition to the normal traffic light the Light Line signals to the pedestrian directly at his or her feet, indicating when it is possible to cross the street without danger. The warning light is integrated into the pavement and functions on a synchronized basis with the traffic light switch system. If the LED down light switches to red, the Light Line also switches to red and warns the pedestrian not to cross. As soon as the traffic light is showing green again, the Light Line also turns green.
This double light signal is intended to bring about a higher level of attentiveness among pedestrians, prompting them to not cross the road when the signal is red, even if no vehicles can be seen at that moment. To get a rapid and reliable light signal, DSTA opted for red and green Golden Dragon LEDs from Osram Opto Semiconductors. These LEDs provide operating times in the nanosecond range, so there are no delays in switching over which provides an increase in safety for pedestrians.
