Japan uses blue LED to suppress suicide significantly (Figure)


In order to prevent the occurrence of a suicide incident, a blue lighting device was installed on the platform of JR Kawagawa Station.

According to the Kyodo News Agency on the 29th, because the blue light helps stabilize people's emotions, blue lighting equipment is gradually being promoted throughout Japan to curb suicide and criminal behavior. Since the Japanese railway company adopted the equipment at the crossing, the incident of suicide has been significantly reduced. People are increasingly expecting the effects of such soft lighting fixtures.

As a killer to prevent railroad crossing accidents, JR West Japan has installed light-emitting diode (LED) lighting equipment at its main sites on the Hanwha and Kansai lines since December 2006. The total number of stations installed has now reached 59.

Previously, accidents caused by bouncing suicides and forced passage of vehicles have emerged endlessly. To this end, the company not only exchanged alarms and railway gates for greater and more conspicuous, but also introduced a laser detection system for obstacles in crossings. In addition, blue lighting equipment is installed, hoping to play a psychological role. According to the company's Osaka branch, the chief of the electrical department, Mori and Leeji said: In order to prevent accidents, the methods that can be used have been tried.

It is understood that there were 35 suicides and accidents in the above 59 stations from April 2005 to the installation of blue lighting equipment, and only two occurred in December 2006. This is also said that: (this kind of lamp) is softer than the mercury light line, making it easy to adapt. And it consumes more electricity and is more environmentally friendly. Received a very high rating.

In fact, the first to implement such measures is Glasgow in the United Kingdom. In 2000, in order to improve the landscape, the city changed the color of the streetlight from orange to blue, and found that this brought the side effect of reducing the crime rate. In 2005, after noticed the case of Glasgow, the Nara County Police Department installed 3000 盏 blue security lights in about 100 places such as bicycle parking lots in residential areas and stations, and the crime rate in the surrounding areas dropped by 15 %. The county police explained that the blue light was very bright at night and the visibility was better. As a result of setting up a blue anti-theft light, residents began patrolling activities, and the awareness of conscious crime prevention was improved.

In addition, in order to heal the driver's fatigue and promote safe driving, China-Japan Expressway Company arranged 152-inch blue lighting equipment side by side at a distance of 1.8 km from the Tokyo entrance. It is said that the garbage bins in the famous high-speed old-age rest area of ​​the Jixian County have been reduced since the nearby lights were replaced with blue.

In this regard, Yuan Yongjingxiang, a color psychology counselor who has provided relevant advice to the Nara police, said: Blue can act on the parasympathetic nerves of human beings, and has the calming effect of calming people in a nervous state.

Regarding the blue light, Yuan Yong pointed out that red and orange would be exciting and have a tendency to contribute to suicide and crime. In turn, blue has a calming effect, perhaps preventing people who attempt to commit suicide by impulsive impulses.
