Prior art

Conventional pedestrian crossing lights have low brightness, which increases the risk of nighttime pedestrian traffic accidents, and when the lights are strongly illuminated, electricity costs are consumed. There is a limit to budget.

In addition, the conventional pedestrian crossing lights have constant lighting intensity regardless of the presence or absence of pedestrians, from lighting after sunset to lighting off before sunrise. There are inadequate disadvantages.

Since crosswalks are a frequent occurrence of night traffic accidents, it is very important to illuminate the lights brightly to prevent night pedestrian traffic accidents.

The 2005 National Police Agency statistics on pedestrian traffic fatalities and traffic accidents during pedestrian crossings show that the number of pedestrians died at night.

※ The number of pedestrian traffic accident deaths (2005 National Police Agency statistics)

Weekly: 875 people (35.6%)

Nighttime: 1,582 people (64.4%)

Total: 2,457 (100.0%)

※ Traffic accidents during crosswalk crossing (2005 National Police Agency statistics)

-369 deaths

-Injured: 9,797

Some local governments have introduced a method of installing one or more additional lighting lamps or using high-brightness lighting lamps with high power consumption in pedestrian crossings where many traffic accidents occur. In such a case, the electric bill is excessively consumed, which is a big burden on the local government. For example, when one 1,000W sodium lamp or two 400W sodium lamps are installed as lighting lamps, the electricity bill costs about 3 ~ 40,000 won per month. Since the pillars of illumination are installed on both sides of the crosswalk, a lot of electricity costs of about 6 ~ 80,000 won per month are consumed per crosswalk.

However, the government is now focusing on reducing electricity costs at night, such as encouraging streetlights to save energy, which makes it difficult for local governments to spend more on electricity by lighting up the lights to prevent crosswalk traffic accidents. The difficulty in catching both rabbits, such as reduced sidewalk traffic accidents and reduced electric energy, is urgently needed to develop a new lighting system to solve this problem.

The object of the present invention created to solve the above problems is as follows.

First, it is an object of the present invention to provide a means for minimizing the traffic accident at night crosswalk by automatically brightening the illumination of the crosswalk when there is a pedestrian.

Second, it is another object of the present invention to provide an economical lighting control device that can use energy efficiently by reducing unnecessary lighting intensity when there is no pedestrian.

Third, another object of the present invention is to provide a means for more reliably detecting the presence or absence of a pedestrian on a crosswalk.

Fourthly, another object of the present invention is to provide a means for providing basic lighting at all times even when the pedestrian detection unit temporarily loses a pedestrian detection function due to weather effects.

Fifth, another object of the present invention is to provide a means for interlocking control of lighting devices on both sides of a crosswalk.
