In general, streetlights are very important facilities to provide convenience to vehicle drivers and pedestrians and to prevent accidents by identifying roadways, roads and surrounding roads, which are installed between the roads and between the roads and the surrounding roads of the buildings.

Background Art [2] Conventionally, a street lamp is composed of a strut installed along a side edge of a sidewalk of a sidewalk, a horizontal support fixed to the upper end of the support and extending in the direction of the road, and a lamp installed at the end of the horizontal support.

Since the height, such as height, can not be adjusted because the support, the horizontal support and the lamp are both fixed, it is necessary to dismantle the existing lamp when the height of the lamp is adjusted due to the change of the surroundings. And wastes time.

In addition, a typical street light has been used as a commercial power source through an underground distribution line. Recently, as a part of green technology, a solar cell module is installed at the top of a pillar so that electricity generated from a solar cell module Street lamps have been developed to reduce environmental pollution and to install street lamps in areas where commercial electricity is not supplied.

However, in the prior art 1, since the solar cell is fixed on the support, the sun's orbit continuously changes in direction and altitude from the sunrise to the sunset, and thus the sunlight can not be effectively collected. As a result, And a large area solar cell module must be used in order to obtain necessary electric power, resulting in an increase in facility cost.

As a prior art related to a streetlight using a conventional solar cell module, Korean Unexamined Patent Application Publication No. 10-2003-0042653 (published on June, 2003) discloses a solar photovoltaic charging device and a streetlight using the same. 2 ") is disclosed.

However, in the prior art 2, since the current collector plate is only horizontally rotated, the current collector plate can not be accurately directed to the sun in consideration of the fact that the orbit of the sun continuously changes in direction and altitude from sunrise to sunset, And the power generation efficiency is lowered. In order to obtain the required power amount, the solar cell module having a large area needs to be used, resulting in an increase in facility cost.

On the input side of the third electromagnetic clutch 710 And the input side and the output side of the first, second and fourth electromagnetic clutches 510, 610 and 810 are separated from each other.

The horizontal rotation support 150 coupled to the output side of the second electromagnetic clutch 710 is rotated horizontally by the rotation of the upper motor shaft 420 coupled to the input side of the third electromagnetic clutch 710, The second gear box 160 coupled to the upper portion of the rotating column 150 and the solar cell assembly 300 coupled thereto rotate horizontally (see FIG. 7).

On the other hand, the rotational force of the lower motor shaft 410 is transmitted to the input side of the first electromagnetic clutch 510 where the input side and the output side are separated, but the rotational force is not transmitted to the output side,

The rotational force of the upper motor shaft 420 is transmitted to the input side of the second electromagnetic clutch 620 where the input side and the output side are separated from each other, but the rotational force is not transmitted to the output side,

The rotational force of the upper motor shaft 420 is transmitted to the input side of the fourth electromagnetic clutch 810 where the input side and the output side are separated, but the rotational force is not transmitted to the output side, so that the later- .

The drive motor 40 is operated to rotate the lower motor shaft 410 and the upper motor shaft 420 to rotate the fourth electromagnetic clutch 810 The input side and the output side are in contact with each other, and the input side and the output side of the first to third electromagnetic clutches 510, 610 and 710 are separated.

The first drive bevel gear 820 coupled to the output side of the sixth electromagnetic clutch 810 is transmitted to the rotational shaft of the upper motor shaft 420 coupled to the input side of the fourth electromagnetic clutch 810, The rotating shaft 840 is rotated by the gear action of the bevel gear 820 and the second driven bevel gear 830 and the rotating arm 850 coupled to the rotating shaft 840 and the solar cell assembly 300 coupled thereto, (See Fig. 8).

On the other hand, the rotational force of the lower motor shaft 410 is transmitted to the input side of the first electromagnetic clutch 510 where the input side and the output side are separated, but the rotational force is not transmitted to the output side, The rotational force of the upper motor shaft 420 is transmitted to the input side of the second electromagnetic clutch 620 where the output side is separated from the output side of the second electromagnetic clutch 620. However, The rotational force of the upper motor shaft 420 is transmitted to the input side of the third electromagnetic clutch 710 where the output side is separated, but the rotational force is not transmitted to the output side, so that the above-described solar battery horizontal rotation operation is not performed.

Further, when the control unit 920 outputs a combination of the up / down operation command, the up / down rotation operation command for lighting, the horizontal rotation operation command for solar cell and the up / down operation command for solar battery, The horizontal rotation operation and the solar cell vertical rotation operation can be performed in combination of two or more.

On the other hand, when the solar cell module 320 is installed so that the sun is oriented in accordance with the direction of the sun corresponding to the time of the first installation and the altitude data, and the current time is between the sunrise time and the sunrise time, The control unit 920 controls the solar cell horizontal rotation driving means 700 to rotate the solar cell module 320 horizontally in the clockwise direction as viewed in the drawing and controls the solar cell vertical rotation driving means 800, By causing the module 320 to rotate up and down, the solar cell module 320 can be accurately oriented toward the sun (see FIGS. 7 and 8).

The control unit 920 stops the horizontal rotation and the vertical rotation of the solar cell assembly 300 by the solar cell horizontal rotation drive means 700 and the solar cell vertical rotation drive means 800. [

When the sunset time has elapsed, the solar cell assembly 300 is maintained in a stopped state until the next sunrise time, or rotated in advance to match the direction and altitude of the sun of the next sunrise time, State can be maintained.

In this way, the solar cell module 320 accurately directs the sun according to the direction and altitude of the sun in real time while following the sun's orbit from the sunrise time to the sunset time until the sunset time, The power generation efficiency can be maximized.

The illuminance sensor 910 senses the illuminance of the road surface such as a road, a sidewalk, a crosswalk, a crosswalk, and the like, and transmits the illuminance detection signal to the controller 920. The controller 920 controls the elevation operation command and / So that the above-described lifting and / or lowering operation such as illumination can be performed.

Meanwhile, the control means 900 may further include an input unit (not shown) so that when the illumination light up and down rotation operation mode is input to the input unit, the above-described illumination light up and down rotation operation may be performed.

By adjusting the illumination direction as described above, it is possible to change the illumination direction of the roadway, the sidewalk, the crosswalk, etc., and effectively illuminate according to the traffic volume and the walking amount of the roadway, the sidewalk and the crosswalk.

While specific embodiments of the invention have been illustrated and described, it will be obvious that the invention may be varied in many ways by a person of ordinary skill in the art.
