The lighting device for a road according to the present invention comprises: a light-emitting unit formed to emit light towards the ground of a road below a sight level of a driver in an edge of a road, and having a color LED including a white light emitting diode (LED) and at least one color of red, green, and blue or a predetermined particular color; a weather signal receiving unit for receiving a weather signal corresponding to a change in a weather situation of a determined region; and a lighting control unit for controlling ON/OFF operation of each of a white LED and a color LED according to the weather signal received through the weather signal receiving unit.

Description

TECHNICAL FIELD [0001] The present invention relates to a road lighting apparatus,

The present invention relates to a road lighting apparatus and a lighting control method thereof, and more particularly, to a road lighting apparatus and a lighting control method thereof that are installed below a driver's eye level of a road railing, an outer wall, The present invention relates to a road lighting apparatus and a lighting control method thereof that can warn and warn a driver in a situation where the weather becomes worse, such as fog or rainy weather.

Generally, roads are mainly used by automobiles and pedestrians. Among them, roads refer to the roads the automobile travels, and India refers to the roads the pedestrians pass.

The driver of the vehicle traveling at a high speed can easily identify the lane and other driving vehicles during the day in which the vicinity can be easily identified. However, at night when the vicinity is difficult to identify, the driver and the road user can easily identify And should be installed near the road so that the road can be used safely.

Therefore, a conventional street lighting device such as a streetlight is provided to illuminate the road and its surroundings so that the road user can easily identify the surroundings.

On the other hand, the road lighting device should improve the visual environment of road users such as driver and pedestrians at night in order to enable road users to use the road safely and comfortably.

However, the conventional lighting apparatus has been designed so that an illumination bulb is provided at the upper end of a pole (pole) installed at a considerable height to illuminate the roads all the way. However, such an illumination device has a problem in that it unnecessarily wastes illumination efficiency because the light source is designed to shine widely from an upper position too far from the road to all directions, that is, to the road as well as the road.

In addition, in the above-described illumination device, when the fog occurs, the progress of the light is scattered due to the water droplet in the air, so that the illumination efficiency of the road is significantly lowered. As a result, the user of the road can effectively Not only can not be identified, but also causes a reflection of light in the field of view of the driver of the vehicle, which causes various safety accidents.

At this time, the visible level measuring unit 160 may include a visible signal transmitting unit 162 and a visible signal receiving unit 164 as shown in FIG. In this case, the visible signal transmitting unit 162 transmits the visible signal of the set intensity in the direction of the visible signal receiving unit 164, and the visible signal receiving unit 164 receives the visible signal received from the visible signal transmitting unit 162 The degree of visibility can be classified into different values and the corresponding weather signal can be transmitted to the weather signal receiving unit 120. [

The tilt adjusting unit 170 adjusts the tilt of the light irradiating unit 110. That is, the tilt adjusting unit 170 can change the direction of the light toward the road surface by adjusting the inclination of the light irradiating unit 110.

The tilt control unit 180 controls the tilt of the tilt adjusting unit 170 based on the wake-up signal received through the wake-up signal receiving unit 120. For example, when it is determined that the set area is darkened based on the weather signal received through the weather signal receiving unit 120, the tilt control unit 180 controls the light irradiation unit The inclination of the tilt adjusting unit 170 can be controlled such that the inclination of the tilt adjusting unit 170 is adjusted upward by a predetermined angle. However, the method of controlling the tilt control unit 170 by the tilt control unit 180 is not limited to the method described above, and the tilt control unit 170 may be controlled using various methods.
