Description

Modular Smart Street Lights

The present invention relates to a street light, and more particularly, to a modular smart street light configured to selectively assemble various modules including an LED module to a post.

The solar street light system belongs to a small solar power generation system and is composed of solar cells, charge controllers, batteries, LED lamps, etc., and energy produced from solar cells during the daytime when the sun is floating is efficiently used through the charge controller. It is configured to light the street by storing it in the battery and consuming the energy stored in the battery at night time after the sun goes down.

However, in general, since the solar panel of the solar street light system is separately installed at one end of the street light column, it is installed with the support frame, so the weight is heavy, and the street light column itself is easily collapsed by external pressure such as wind due to its own load applied to the street light column. There was this.

In addition, in the case of an offense area, an additional CCTV is installed independently on one side of the solar LED street light, but a separate wired/wireless communication device must be provided to transmit the image data captured by the CCTV to the outside, thereby communicating with the power facility. In addition, since it must be additionally installed, there is a problem that it takes a long time to install and requires a lot of cost.

In addition, conventionally, streetlights having various shapes may be installed on one road without a sense of unity, and accordingly, a problem has been raised that the urban landscape is deteriorated.

In addition, the support bar is configured to support the extension bar, one end of which is fixed to the second coupler and the other end of the extension bar.

These first and second couplers are spaced apart from each other up and down, each of which is one of a post (1), an alarm module (4), a CCTV module (5), a gateway module (3), and a cell module (6). Can be combined in an assembly way.

Hereinafter, the solar cell module 6, which is one configuration of the present invention, will be described in detail with reference to FIGS. 4 to 9.

It is preferable to assemble the solar cell module 6 according to the present embodiment at the top of the modular smart street light so that the light collection efficiency is improved.

The solar cell module 6 tracks the altitude and azimuth angle of the sun using a shadow, and based on this, controls the direction in which the solar panel 10 faces perpendicularly to the incident angle of sunlight, thereby increasing light collection efficiency. It is configured to give, and its main configuration is characterized in that it includes a light tracking unit 100, a driving unit 200, and a control unit 300 as shown in FIG. 4.

First, the light tracking unit 100 is configured on the solar panel 10 and is configured on the principle of tracking the incident angle of sunlight using a shadow generated by sunlight. Hereinafter, various embodiments will be described in detail. I will explain.

In addition, the driving unit 200 is connected to the solar panel 10 as shown in FIG. 4 to control the vertical angle and left and right rotation of the solar panel 10.

In this case, the driving unit 200 may be applied to various conventional techniques configured to control the angle of the solar panel 10 at various angles such as up, down, left and right, and a detailed description thereof will be omitted.

Subsequently, as shown in FIG. 4, the control unit 300 is connected to the light tracking unit 100 and the driving unit 200 to enter the solar panel at an incident angle of the sunlight tracked by the light tracking unit 100. It is configured to adjust the angle of the solar panel 10 by operating the drive unit 200 so that (10) faces vertically.

Meanwhile, the light tracking unit 100 is disposed horizontally on the plane of the solar panel 10 as shown in FIGS. 5A to 5B, and is disposed at the center of the solar panel 10 as shown in FIG. 5A. Can be.

At this time, when the light tracking unit 100 is disposed in the center of the solar panel 10, a space is generated in the condensing module (not shown) as much as the area where the light tracking unit 100 is disposed, so that the light collection efficiency may decrease. Bar, preferably, it may be configured to be disposed in the outer region of the solar panel 10 as shown in FIG. 5B.

Hereinafter, with reference to FIGS. 6 to 9, the light tracking unit 100, which is one configuration of the present invention, will be described in more detail.

First, the light tracking unit 100 according to the present invention is characterized in that it includes a base plate 110, a partition plate 120, and a sensing member 130, as shown in FIGS. 6A and 6B.

The base plate 110 is installed parallel to the solar panel 10 as shown in FIG. 5 and the like.

In addition, the partition plate 120 protrudes from the base plate 110, and the first plate 121, the second plate 122, the third plate 123, and the fourth plate 124 are at the same point. The first plate 121, the second plate 122, and the third plate 123 as shown in FIGS. 6 to 7 are configured to form a'十 (ten)' shape by extending from each of the four directions. And the fourth plate 124 allows the quadrant to be partitioned based on the center of the base plate 110.

That is, the base plate 110 is divided into a first quadrant (I), a second quadrant (II), a third quadrant (III) and a fourth quadrant (IV) by the partition plate 120.

In this case, the partition plate 120 includes the first plate 121, the second plate 122, the third plate 123, and the fourth plate 124 in a right-angled triangular shape, as shown in FIG. 6A. In some cases, as shown in FIG. 6B, the first plate 121, the second plate 122, the third plate 123, and the fourth plate 124 may each be configured in a rectangular shape.

Subsequently, the sensing members 130 are configured on each of the quadrants partitioned by the partition plate 120, and the solar region to which sunlight is directly irradiated to the corresponding quadrant and the sunlight are transmitted to the partition plate 120. It is configured to distinguish and sense the shadow area S generated by being covered, and at this time, an illuminance sensor or the like may be applied as the sensing member 130.

With the above configuration, the light tracking unit 100 can detect the direction in which the sun moves based on the shadow generated by the partitioning unit, and the control unit 300 drives the driving unit 200 so that the sensing member By adjusting the angle of the solar panel 10 so that the shadow area S generated in the 130 is minimized, the solar panel 10 can be controlled to always maintain a vertical relationship to the incident angle of sunlight.

Looking at the mechanism of the light tracking unit 100 in more detail, the incident angle of sunlight is irradiated perpendicularly to the light tracking unit 100 in a state in which the light tracking unit 100 is arranged as shown in FIG. 7 and then the second quadrant When moving to the (II) side, the shadow is generated only in the first quadrant (I), the third quadrant (III), and the fourth quadrant (IV) as shown in the drawing, so the sensing member 130 controls the sensing signal that senses it. By transferring to 300, the control unit 300 drives the driving unit 200 to change the angle of the solar panel 10 to the side of the second quadrant (II) where no shadow is generated (in the direction of the arrow indicated on the upper left of the drawing). ) To maintain the solar light incident angle and the solar panel 10 in a vertical relationship, and accordingly, the light collecting efficiency of the solar panel 10 can be improved.

At this time, the second quadrant (II) side corresponds to the range of 90° and 180° in the drawing, and if the sun moves in the direction of θ1 in the drawing, the solar panel 10 is in the direction of the arrow indicated on the upper left of the corresponding drawing. If this angular displacement occurs, a vertical relationship between the solar incident angle and the solar panel 10 can be maintained.

However, if the sun moves in the direction of θ2 less than θ1 or θ3 greater than θ1 within the range of 90° and 180° on the drawing, even in that case, the first quadrant (I), the third quadrant (III), and the fourth quadrant (IV) ), so if the angle of the solar panel 10 is simply adjusted to the second quadrant (II) side (in the direction of the arrow indicated at the top left of the drawing), the solar light incident angle and the solar panel 10 It becomes impossible to maintain a vertical relationship.

In order to compensate for this problem, in the present invention, as shown in FIG. 8, a rotating part 140 for rotating the base plate 110 may be further provided in the light tracking part 100. In this case, the rotating part 140 It may be configured to be rotationally controlled by the control unit 300.

That is, the control unit 300 deviates from the vertical relationship between the solar incident angle and the solar panel 10, as shown in FIG. 9A, and is formed by the partition plate 120 from among the first to fourth quadrants (IV). When a shadow is generated in the four quadrants, the base plate 110 is rotated clockwise or counterclockwise by controlling the pivoting unit 140, so that the shadows change from the first quadrants (I) to the fourth as shown in FIG. 9B. The moment when only two of the quadrants (IV) are generated, the driving of the rotating part 140 is stopped.

Thereafter, the controller 300 controls the driving unit 200 as shown in FIG. 9B to display the solar panel 10 on the opposite side of the shadow area S created in the two quadrants (displayed on the upper left of the drawing). By angular displacement in the direction of one arrow), the angular displacement of the solar panel 10 according to the positional displacement of the sun can be accurately achieved, that is, a more accurate vertical relationship between the solar incident angle and the solar panel 10 can be achieved. It becomes.

That is, as shown in FIG. 9B, when the shadow area S is generated only in the third and fourth quadrants (III) and (IV), the controller 300 operates the driving unit 200 to shadow the solar panel 10. When displaced toward the side of the second plate 122, which is the common opposite side of the area S (in the direction of the arrow indicated at the top left of the drawing), the shadow area S disappears in all quadrants at a certain point, and then the control unit 300 Stops the operation of the driving unit 200 so that the solar light incident angle and the solar panel 10 have a perfect vertical relationship.

On the other hand, as shown in Fig. 6A, the partition plate 120 is preferably configured in a form in which the center is highest and the height decreases toward each end. As shown in Figs. 7, 9A and 9B, If the angle of incidence is not in a vertical relationship with the solar panel 10, the shadow is generated in a form that gradually increases in area from the end of the partition plate 120, so that the sensing member 130 can more accurately recognize whether the shadow is generated. It becomes.

That is, when sunlight is covered by each plate and a shadow is generated, the shadow has a certain pattern in a triangular shape gradually increasing in area from the end of the partition plate 120 as shown in the drawing, so that the sensing member 130 It is possible to more clearly grasp whether or not a shadow is generated.

In other words, as the altitude or azimuth angle of the sun changes and the angle of incidence of sunlight increases away from the vertical relationship with the solar panel 10, the shape of the shadow maintains a triangular shape, but the height and area become larger, so the sensing member In (130), it is possible to estimate the moving distance of the sun based on the height and area of the shadow, so that more accurate data about the angular displacement that the solar panel 10 will proceed to have a vertical relationship with the incident angle of sunlight can be inferred. It becomes.

If the shape of the first plate 121 to the fourth plate 124 is formed in a general plate shape rather than a shape that decreases in height toward the end as in this embodiment, the first quadrants (I) to the fourth quadrants (IV) ), the shape of the shadow generated by the sun is not uniform, and the shape of the shadow is not regularly changed when the sun moves, so the sensing member 130 can only detect the presence or absence of the shadow for each quadrant, thereby accurately determining the distance of the sun. It becomes untraceable.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of the person skilled in the art using the basic concept of the present invention defined in the following claims are also present.
