Description

Fused LED street light device for secondary accident prevention system{Street lamp having secondary traffic accident prevention system}

The present invention relates to an LED street light device, and more specifically, a secondary accident prevention system fusion LED street light that prevents a secondary traffic accident of a subsequent vehicle in advance in the event of a traffic accident by using the LED street light installed on the roadside. It is about the device.

In general, street lights installed at regular intervals on roadsides are road facilities that are installed for the safety and security of vehicles or pedestrians driving the road at night by illuminating the road at night.

Vehicles operating on highways among roads where such street lights are installed usually travel at a speed of more than 100 km/h, so it is difficult for the driver to quickly recognize an accident in the event of an accident in front, The possibility of secondary collisions is inherent.

In particular, because the clock is not good on a foggy day or at night, it is often possible to avoid a second accident due to an increase in the stopping distance because the driving speed is high even if an accident vehicle in front is found and the speed is reduced. .

In addition, since the accident situation cannot be grasped on a curved road, etc., even when the clock is good, secondary accidents may also occur.

For this reason, a large number of accidents more than multiple collisions occur on the highway, but conventionally, no means are provided to prevent such a series of collisions.

In particular, the proportion of secondary traffic accidents occurring after the primary traffic accident continues to increase, and the main factor in the secondary traffic accident is neglect of the driver's forward attention.

However, even though the driver is paying attention to the front view, there are cases in which it is impossible to cope with the blind spot and insufficient action after the first accident, or because the driver is aware of the accident at too close a distance. The damage is much greater than the first car accident, fatal, and the mortality rate is also high.

On the other hand, conventionally, the vehicle is provided with a traffic safety tripod as shown in FIG. 1, and the traffic safety tripod is folded and stored in the trunk of the vehicle.

The traffic safety tripod 10 forms a triangle, and is provided with a support portion for standing a tripod on the back.

Therefore, the traffic safety tripod 10 allows the driver of the vehicle coming from the rear side to recognize the accident situation in front of the vehicle when the triangular reflector 11 on the road faces backward when installed at the rear of the accident vehicle. It will perform the function of inducing bypass.

However, such a traffic safety tripod 10 is installed directly at a certain distance from the rear end of the vehicle by the driver of the accident vehicle. In this process, there is a problem that the driver is at risk of a second accident.

2 and 3, the LED housing 300 according to the present invention is provided at the upper end of the support 100 and the support 100, the module housing 200 to be provided with the LED module 300 to be described later is embedded ).

Here, the pillar 100 is a pillar installed vertically on the ground, and its upper end is formed to be vertically bent for connection with the module housing 200, and in this embodiment, only the upper end of the bent pillar 100 is It will be shown to replace the description of the prop 100.

Traffic accident detection systems 400 and 500 are configured in the module housing 200, and vehicle traffic detection units 410 and 510 for detecting the vehicle speed are included in the traffic accident detection systems 400 and 500. Is included.

Therefore, in the traffic accident detection system 400 or 500, it is possible to determine whether or not a traffic accident has occurred by the vehicle speed detection units 410 and 510.

That is, in the course of a traffic accident, the speed of the vehicle is rapidly decelerated and slowed down or stopped. Accordingly, if the vehicle speed is continuously monitored, it is possible to determine whether a traffic accident has occurred.

Accordingly, the vehicle speed detection process may be performed by the vehicle speed detection unit 410 included in the traffic accident detection system 400 as shown in FIG. 4.

As shown in FIG. 4, the vehicle speed sensor 410 according to an embodiment of the present invention includes a vehicle motion sensor, a clock generator 412, a map information database 413, and a calculator 414. Can.

The vehicle motion sensor is a device for determining the speed of the vehicle, and may be suitably configured as a camera. Hereinafter, a camera will be described as an example of the vehicle motion sensor.

The camera 411 means a photographing means for photographing image information of a vehicle, and the clock generator 412 means a means for providing a clock so as to grasp the photographing time.

In addition, the map information database 413 is a storage medium in which location information necessary for operating the vehicle speed sensor 410 is stored, where road map information, street light installed location information, intersections and pedestrian crossing locations are stored. have.

The operation unit 414 may be installed in any street light or may be constructed in a server form capable of communicating with each street light through wire or wireless.

In particular, when the camera 411 is installed on a street light to photograph a vehicle, it is possible to check an image of the vehicle photographed at regular intervals.

When photographing with the camera 411, the photographing time information generated by the clock generator 412 is stored together with the image of the vehicle.

The photographed vehicle image and photographing time information are input to the calculation unit 414. The calculating unit 414 calculates the speed of the vehicle by using the received vehicle image and shooting time. The calculation unit 414 calculates the speed of the vehicle passing through each streetlight by using the location of each streetlight received from the map accuracy database 413 and the distance between the streetlights and the time required for a specific vehicle to pass between each streetlight. Pay.

As a result, the calculation unit 414 continuously calculates vehicle information in the section between each street light and monitors whether there is a section in which the speed is rapidly reduced, and when a section in which the speed is rapidly decreased occurs, a traffic accident occurs in the section. In response to this, the red LED warning light 420 provided in the module housing 200 is flashed to inform the rear driver that a traffic accident has occurred in the front.

On the other hand, even when the vehicle is waiting for a signal while passing through an intersection or a pedestrian crossing, the vehicle speed is reduced.

At this time, in the process of calculating the speed of the vehicle, the calculating unit 414 refers to the map information database 413 and checks whether an intersection or a pedestrian crossing exists in a speed reduction section of the vehicle, thereby reducing the speed by the intersection or the pedestrian crossing. If confirmed, it is not judged as a traffic accident even if the vehicle speed is reduced.

The above-described vehicle speed calculation process by the vehicle speed detection unit 410 is described based on one vehicle, but may be simultaneously performed for a plurality of vehicles photographed by the camera 411. That is, it is also possible to simultaneously calculate the speed of each vehicle while individually recognizing the vehicle through signal processing of the captured image. By calculating the speeds of several vehicles at the same time, it is possible to more accurately determine whether the vehicle has stopped due to a signal waiting at an intersection or a pedestrian crossing, or has stopped due to a traffic accident.

The operation unit 515 may be installed in any street light, or may be constructed in a server form capable of communicating with each street light by wire or wireless.

The strength of the Wi-Fi signal detected by the Wi-Fi receiving module 512 installed in the street light depends on the distance between the street light and the vehicle. That is, when the distance between the vehicle and the street light is close, the strength of the received Wi-Fi signal is counted. On the contrary, when the distance increases, the strength of the Wi-Fi signal is weakened.

That is, since the strength of the Wi-Fi signal varies according to the distance between the transmitting end and the receiving end, if the calculation according to the triangulation method is performed using the signal received from the Wi-Fi receiving module 512 installed in at least three street lights, the position of the vehicle is determined. It can be specified more accurately.

When matching the location of the specified vehicle to the map provided by the map information database 514, it is possible to calculate the path and the moving distance of the vehicle. Meanwhile, when the calculated moving distance of the vehicle matches the time information provided by the clock generator 513, the vehicle speed can be calculated.

That is, the second heat sink 340 is provided with a support block 344 fixedly installed on the upper surface of the second heat sink 340, and between the second rotation shaft 370 and the support block 344 is provided in the support block 344. In a state in which a bearing (not shown) is interposed, the second rotating shaft 370 is coupled to be rotatably provided, and the pinion gear 380 is fixedly coupled to the front end of the second rotating shaft 370 and fixed to the rear end. The second sprocket wheel 371 is axially coupled and fixed.

The second rotation shaft 370 provided as described above is provided at the center of the ring gear 220, thereby being the rotation center of the rotated module housing 200 and the LED module 300.

Meanwhile, when the second rotation shaft 370 is rotated, the pinion gear 380 and the second sprocket wheel 371 are interlocked and rotated at the same time, and the second sprocket wheel 371 is the first of the first rotation shaft 150. It is connected to the sprocket wheel 151 and the chain 152 to be interlocked.

Therefore, when driving the motor 110, the rotation of the driving gear 120 is a ring gear 220 -> interlocking gear 140 -> first rotating shaft 150 -> first sprocket wheel 151 -> chain (152) -> second sprocket wheel 371 -> second rotation shaft 370 -> pinion gear 380 -> while being sequentially transmitted to rack gear 351, the module housing 200 is rotated, and at the same time The light blanking plate 350 is drawn out.

At this time, the rotation of the module housing 200 is rotated around a second rotation shaft 370 provided with a bearing interposed in the support block 344, and a light blanking plate that is simultaneously withdrawn from the rotation of the module housing 200 The light blocking plate 350 provided on the opposite side to the rotational direction of the module housing 200 is provided to the 350. That is, as shown in FIGS. 10 and 11, when the module housing 200 is rotated to the right and intends to intensively provide illumination to the right area, that is, the accident area, the light-blocking plate on the left of the light-blocking plates 350 on both sides The 350 is drawn out and the light is blocked from being irradiated to the left region, so that the light can be concentrated and irradiated to the accident region.

On the other hand, the operation of the motor 110 as described above may be automatically operated in conjunction with the traffic accident detection system 400, 500, or remotely the operation of the motor 110 by using a communication means in the outdoor lighting control center. It can also be controlled.

The operational relationship of the secondary accident prevention system fusion LED street light device according to the present invention as described above will be described.

First, since the operational relationship of the traffic accident detection system 400 and 500 has been described in detail in FIGS. 4 and 5 described above, repeated description thereof will be omitted, and traffic accidents may be caused by the traffic accident detection system 400 or 500. When it occurs, the operation relationship of the LED street light device will be described.

That is, in the LED street light device of the present invention, the vehicle speed detection unit 410 and 510 of the traffic accident detection system 400 and 500 provided therein detects the speed of the vehicle driving on the road to determine the presence or absence of a traffic accident. When the traffic accident is detected, the red LED warning lights 420 and 520 provided in the module housing 200d are blinked to inform the rear driver of the traffic accident.

In addition, a large amount of heat is generated from the LED of the LED module 300 that is lit when the LED street light device is operated, and the PCB on which the LED is mounted. At this time, high temperature heat is generated from the LED, but this heat is the LED. Rapid heat conduction is performed by the first heat sink 320, the second heat sink 340, and the heat pipe 330 provided in contact with the upper surface of the module 300 to radiate heat.

In particular, the plurality of heat pipes 330 provided between the first and second heat sinks 320 and 340 are provided adjacent to each other in the center of the first heat sink 320 corresponding to the position of the LED, and thus are generated in the LEDs. By rapidly dissipating high-temperature heat, it is possible to prevent damage to the LED module 300 and shortened life due to temperature increase.

On the other hand, the LED street light device as described above, as shown in Figures 8 and 9, the LED module 300 is in a state facing the outdoor light in a state facing the ground, the light shielding plate 350 is the second heat sink (340) All of them are raised to the upper part and are operated in a provided state.

In this state, the LED street light device detects a traffic accident and at the same time, the module housing 200 is rotated to intensively illuminate the traffic accident area. That is, when the module housing 200 is rotated to the accident area, the light shielding plate 350 provided on the opposite side to the rotation direction of the module housing 200 along with the rotation of the module housing 200 is drawn out to the light source side. By covering, it is possible to intensively illuminate the light into the accident area by preventing dispersion of light.

If this is described in detail with reference to FIGS. 10 and 11, when the motor 110 is driven and the drive gear 120 is rotated counterclockwise as in FIG. 11, the ring gear fixed to the inner circumference of the module housing 200 (220) is also rotated in a counterclockwise direction, the module housing 200 is rotated counterclockwise as shown in FIG. 11 in a state coupled to the support 100 to provide illumination to the right area (accident area), The left area (non-accident area) obscures light to prevent light dispersion.

At this time, the module housing 200 rotated in a state coupled to the support 100 rotates around the center of the ring gear 220, that is, the second rotation axis 370.

On the other hand, in addition to the movement of the module housing 200 as described above, the light shielding plate 350 on the left is withdrawn when the module housing 200 is rotated on the basis of FIG. 11, which is rotated when the ring gear 220 is rotated. The meshed interlocking gear 140 is rotated counterclockwise, and the first rotational shaft 150 fixed to the interlocking gear 140 is also rotated counterclockwise like the interlocking gear 140, and the first rotational shaft 150 The first sprocket wheel 151 fixed to) is also rotated counterclockwise.

Then, the second sprocket wheel 151 connected to the first sprocket wheel 151 and the chain 152 is also rotated counterclockwise, and the second rotation shaft 370 to which the second sprocket wheel 371 is fixed is a support block The pinion gear 380 fixed thereto is rotated counterclockwise while being rotated counterclockwise in place in a fixed state coupled to 344.

As a result, as the pinion gear 380 is rotated counterclockwise, the gear portion 381 of the pinion gear 380 is engaged with the rack gear 351 of the left light shielding plate 350 to bring the light shielding plate 350 into account. The LED light source is lowered to the side, and the right light blanking plate 350 is made of the power because the inorganic gear 382 of the pinion gear 380 is located in the rack gear 351 of the right light blanking plate 350. 2 The heat sink 340 is maintained at the upper position.

At this time, the LED module 300 is rotated integrally as the module housing 200 separately from the second rotating shaft 370 around the second rotating shaft 370, and the pinion gear 380 is the LED module 300. At the same time as the rotation of the second rotation axis 370, the LED module 300 is rotated integrally in the same direction. In this process, both the LED module 300 and the pinion gear 380 simultaneously rotate the second rotation axis 370. Since it is rotated as a reference, malfunction caused by interference between the pinion gear 380 and the rack gear 351 can be eliminated.

In addition, the light-blocking plate 350 is drawn out from the moment when the gear portion 381 of the pinion gear 380 rotated as above is engaged with the rack gear 351 of the light-blocking plate 350.

Accordingly, as described above, the LED module 300 is rotated by the module housing 200 to illuminate the light to the accident area as much as possible, while the pinion gear 380 is rotated at the same time as the LED module 300 is rotated to the non-accident area side. By drawing out the light shielding plate 350 of, the dispersion of light is blocked, so that light can be more intensively irradiated to the accident area.

It is clear that modification and improvement are possible.
