The present invention relates to an LED traffic light system having a built-in remaining time display function.

According to the recently published 'Comparison of Traffic Accidents in OECD Member Countries', Korea and Japan ranked first and second in the 'Traffic Accident Rate per 10,000 Cars' section. This is attributed to the fact that after the IMF bailout, the economy gradually showed signs of recovery and economic activity became active, resulting in an increase in the accident rate along with the frequency of vehicle operation.

The worrying point is that despite the expansion of traffic safety facilities and the improvement of traffic conditions, which are never short of economic growth, the overall traffic culture has worsened, with the number of casualties increased by three times in recent decades. There is a situation.

On the other hand, traffic accidents and casualties were reported to decrease slightly in 2001 and 2004, when the number of traffic violations was greatly increased. This is because the regulation leads to the right driving habits.

However, there is a problem that requires a lot of manpower for the purpose of preventing traffic accidents in order to continuously crack down on traffic law violations, and unmanned enforcement equipment is also easy to install, such as the need to embed loop sensors on the road. There was a problem that takes a lot of installation cost.

In addition, there is a problem that the current CCTV monitoring the situation of the intersection, but had to be installed separately from the traffic light, the current CCTV has a limited viewing angle, so it was too difficult to cover all parts of the intersection, which is why Often, video alone failed to identify the cause of the traffic accident.

In addition, the current traffic light signals only the colors of green, red, and yellow, so the remaining time of the signal, especially the remaining time of the green signal, cannot be known accurately, causing the speeding in the car and jumping away from the crosswalk. Create inconveniences and risks of crossing.

Recently, a device for displaying a remaining time on a traffic light has been studied due to the above problems.

However, the traffic light having the remaining time indicator according to the prior art has to be provided with a separate space for the remaining time indicator, and the conventional traffic lights must be replaced with the case as a whole, the traffic signal and the remaining time indicator There is a problem that the driver's field of view is dispersed because the spaces are spaced apart from each other so that the traffic signal and the remaining time cannot be grasped at a glance, which may cause a traffic accident.

On the other hand, conventional traffic lights use a color filter to collect the light of a white light bulb, which is a traffic light source, in a reflector and to display the standard index red, yellow, and cyan colors of the traffic light. However, such a conventional incandescent light bulb signal lamp uses a low-efficiency incandescent light bulb, so the power consumption is high, the life of the light bulb is short, at least once every six months to replace the maintenance and repair costs associated with replacing the light bulb.

In addition, since the bulb has a characteristic of suddenly shutting down, planned maintenance is not possible, and there is a high social loss due to the concern of traffic safety accidents and the disturbance of traffic flow, and the light enters through the color filter under the strong summer sun. The light is reflected by the reflector and radiated outside the signal, which may cause the traffic light to be mistaken, which may cause an accident.

Recently, due to the above problems, researches and experiments on LED traffic lights using semiconductor LED lamps have been steadily made.

Traffic lights are rapidly being replaced by regular light bulbs with LED lights. In addition to the advantages of low power and high brightness, LED traffic lights can provide a variety of additional functions because they are easy to control electronically.

However, even in the case of a conventional LED traffic light, when some LED lamps are abnormal, the parts are not lit, so that the overall visibility is lowered. there was.

It is possible to monitor in real time at the control center and at the same time reduce the amount of image information stored in the storage through the image control unit, while traffic accidents are generated at the intersection through the image information stored around the red signal of the traffic light. In order to effectively identify the cause of accidents In order to use the LED lamp of low power and high brightness as a light source of the traffic light, and to display the remaining time at the traffic light itself without having a separate remaining time indicator, a plurality of LED signal modules and a plurality of LED display modules may be used. In combination with each LED module by separating the LED lamps to control the lighting by LED lamps in the event of abnormality in some LED lamps by turning on other LED lamps that do not have a built-in camera capable of emergency switching The present invention provides an LED traffic light system capable of displaying the remaining time.
