Description

System for crime prevention with using streetlight apparatus

The present invention relates to a street light device having a crime prevention function and a crime prevention system using the same. More specifically, the street lamp device in which the light emission angle and light emission intensity are adjusted according to the occurrence of an event, and the event occurrence area and the surrounding area based on the event occurrence information. It is about a crime prevention system that controls the light emission angle and light emission intensity for a street lamp device.

CCTVs are installed in downtown areas and alleys of residential areas to actively respond to crimes while monitoring people coming and going, and using these CCTVs, a crime prevention system is being built.

In the case of downtown, at night time when there is a lot of traffic, light is emitted by street lamps even in areas where sufficient brightness can be maintained even without street lamp lights to maintain the same brightness as daytime due to light emission from building lights and neon signs of businesses. There is a problem in that unnecessary power is consumed according to the operation.

On the other hand, in the early morning hours when business is closed, the lights of buildings and businesses are almost turned off and the streets are illuminated with light emitted from intermittently installed street lamps, so there are partially dark areas where street lights do not reach, and crimes occur in these dark areas. In this case, there is a problem in that it is difficult to understand the situation through CCTV, etc., even if CCTV is installed in an adjacent location.

In addition, in order to sufficiently illuminate the alleys in residential areas where there are few people at night, it is necessary to install the streetlights as densely as possible. Due to this, there is a problem that the elderly or women who come and go in the alleys of sparsely populated residential areas have a fear that they may be the targets of crimes.
