Description

TECHNICAL FIELD [0001] The present invention relates to a dimming control system and a dimming control method,

The present invention relates to a system and a method for controlling the illuminance of an LED lamp tunnel, and more particularly, to a system and a method for controlling the illuminance of an LED lamp tunnel by detecting the failure of each tunnel in a tunnel, raising the illuminance of surrounding tunnels, To a dimming control system and method, such as an LED tunnels, which allow the road surface brightness in the entire section to be maintained above a reference value.

As the speed of increase of vehicles in Korea has increased tremendously, various roads of vehicles have been expanded, opened, and newly established. As the roads are opened or newly constructed, mountainous areas with comparatively low land costs are used according to geographical and economic conditions. As a result, most of the roads are being opened and expanded.

When the vehicle passes through a tunnel, a rapid change in the brightness of the inside and outside of the tunnel causes the driver to be temporarily unable to accurately recognize the object ahead. This complication has a problem that the driver temporarily gives visual impairment to cause a traffic accident, or the driver operates the braking device to decelerate the speed, thereby causing traffic congestion.

Fig. 1 is a view showing a configuration of a general tunnel illumination.

The inside of the tunnel is divided into a boundary portion, a transition portion, a base portion and an exit portion along the traveling direction of the vehicle, and an entrance connection portion and an exit connection portion are located at the tunnel entrance and exit. The tunnel lighting consists of a boundary lighting section that allows observation of an object inside the tunnel in a state adapted to the bright brightness of the outdoor area and an entrance lighting section which comprises a transition section illumination section for giving a luminance background to the observed object in a state of visual adaptation. An exit section illumination that provides a luminance background to overcome the visual disturbance caused by the high brightness of the outdoor visible through the tunnel exit during the daytime, And an entrance connection illumination and an exit connection illumination installed on the exit access road so that the situation inside and outside the tunnel can be determined.

Korea Industrial Standard KSC 3703 specifies the tunnel lighting standards. Entrance lighting refers to lighting installed in addition to the basic lighting for the purpose of solving the visual problem in the vicinity of the tunnel entrance during the daytime. The basic sub-illumination refers to the illumination that ensures almost uniform brightness over the entire section of the tunnel in order to ensure the visibility of the driver in the tunnel during day and night. Exit lighting refers to the lighting installed in addition to the basic sub-lighting as necessary to solve the visual problems caused by the glare of outdoor high brightness visible through the tunnel exit during the daytime.

In KSC 3703, the average road surface brightness is defined in each section of boundary / transition part / base part / exit part of the tunnel according to the luminance outside the tunnel and the average traveling speed of the vehicle on the road.

FIG. 2 is a view showing a conventional tunnel lighting system for satisfying the road surface luminance in the tunnel specified in KSC 3703 according to the luminance outside the tunnel. Conventional tunnel lighting systems control the road surface brightness in tunnels with a spike control system.

As shown in Fig. 2, in the case of the tunnel illumination system including the first to twenty-first to sixth tunnels 26 and the like, the first wiring 27 and the second tunnel 27 are provided in the first tunnel 21 to the sixth tunnel 26, And a second wiring 28 are respectively provided. 2, the first wiring 27 connects all the first tunnels 21 to the sixth tunnels 26, and the second wiring 28 connects the first tunnels 21 and the third tunnels 26, Only the tunnels 23 and the fifth tunnels 25 are connected. The control unit (not shown) measures the external luminance of the tunnel. If the measured external luminance is higher than the reference luminance, the control unit controls the switch 29 so that the power supply B + is supplied to the first wiring 27, And controls the switch 29 so that the power supply B + is supplied to the second wiring 28 when the external brightness is lower than the reference luminance, thereby lowering the illuminance of the tunnel illumination.

In the conventional tunnel illumination system, a plurality of wirings are connected to a plurality of tunnels of uniform illumination in advance, and power is supplied to one of the plurality of wirings according to the external luminance, And controls the illuminance. 2, the actual tunnel illumination system is constructed with very complicated wiring in consideration of the change in the external luminance depending on the night / day, the season, the weather and the like, and switching to a preliminary tunnel in case of failure such as a tunnel .

The conventional tunnel illumination system selectively turns on or off the power supply B + to the first wiring 27 and the second wiring 28 according to the external luminance, thereby lighting or turning off the tunnels connected to the wiring. That is, the conventional tunnel illumination system illuminates the interior of the tunnel with a plurality of tunnels and the like having a uniform illuminance, and adjusts the number of tunnels or the like to be turned on according to the external luminance so that the road surface luminance in the tunnel section satisfies the standard.

In such a conventional tunnel lighting system, if any of tunnels or the like that are lighted is turned off due to a failure, the brightness of the road surface illuminated by the failure tunnel becomes darker than the reference value, thereby hindering safe operation of drivers. In addition, since a preliminary tunnel or the like must be additionally connected in case of failure of an arbitrary tunnel or the like, the wiring of the tunnel illumination system becomes complicated.

SUMMARY OF THE INVENTION It is an object of the present invention, which has been devised to solve the above-mentioned problems of the prior art, to provide a tuning system for a tunnel, And to provide a dimming control system and method, such as an LED tunnels, which can satisfy the above-mentioned requirements.

A dimming control method such as an LED tunnel according to the present invention includes a first step of collecting status information of a plurality of LED tunnels installed in a tunnel and detecting a faulty LED tunnel and the like, And a second step of raising the temperature.

As described above, according to the present invention, when the LED in the tunnel is broken, the illuminance of the surrounding LED tunnels is raised, so that even if the faulty LED tunnels are not replaced or the tunnels are not switched to the spare tunnels, So that it is possible to provide an optimal driving environment for the driver.
