DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The problems and solutions to be solved by the present invention will become more apparent from the following detailed description of various embodiments shown in the accompanying drawings.

As described above, the present invention can facilitate the change of the position of sunlight even in a strong intensity of light emitted from sunlight or in an illuminance range in which a large amount of light is irradiated. In addition, the solar panel for producing solar power or the solar panel for producing heat provides an effect of making it easier to track the position of the solar light.

In describing a specific embodiment of the present invention, the configuration and operation thereof are illustrated by the drawings of the present invention will be described as at least one embodiment, whereby the technical spirit and core of the present invention Configurations and operations should not be limited.

For reference, in designating reference numerals in the drawings to be described in the present invention, it should be noted that the same components are given the same reference numerals as much as possible, even if shown in different drawings.

Hereinafter, with reference to the accompanying drawings for the solar light detection device for tracking the position of the present invention will be described in detail.

As the optical sensor used as one means for solving the problems of the present invention, various types such as CdS (cadmium sulfide cell) and phototransistor are used, and among them, the CdS applied to the present invention is irradiated. Depending on the amount of light, the capacitance of the resistor (or sometimes referred to as the 'resistance value') changes and the sensing operation takes place.

For example, most of the CdS has a resistance value of 5Ω (ohm) to 250KΩ (kiloohm), which operates by sensing a dose of light, and in the dark state, has a high resistance value and then is applied to the surface of the CdS. As the light irradiated becomes brighter, its internal resistance value is lowered, which is called a light-on type.

In other words, when the light emitted from the sunlight is irradiated on the surface of the CdS, the resistance value of the CdS decreases, and at this time, the current flowing through the CdS increases, and thus, the aforementioned Light-On Type operation is performed, and thus a detection signal is generated by converting an optical signal into a current signal.

Next, in the present invention, as a means for solving the problems of the present invention as described above, a pair of the first optical sensor and the second optical sensor for detecting the solar light for tracking the position of the solar light sensor holder The configuration installed in the following will be described.

1 is an exploded view showing an example in which a pair of optical sensors for detecting sunlight for tracking the position of sunlight according to the present invention are partially cut out respectively installed in the optical sensor holder.

First, the optical sensor holder (100) (100-1) of the present invention is located in the first and second light sensor 400 and the south and north directions for detecting the sunlight 700 located in the east and west directions made of a pair The second optical sensor 400-1 for detecting the sunlight 700 is installed, respectively.

At this time, since the optical sensor holder 100, 100-1 may be manufactured in various shapes such as a cylindrical shape, a square pillar, and a polygonal pillar, the shape of the optical sensor holder 100 and 100-1 may not be limited.

In addition, the first recess 121 is formed to be symmetrically separated at both sides with respect to the partition 300 fastened to the inner center portion of the body 110 provided in the optical sensor holder 100, 100-1. ) And the second recess 121-1.

Here, the partition wall 300 is to sufficiently generate the shadow generated by the sunlight 700 on the first groove portion 121 side and the second groove portion 121-1 side.

In addition, a filter unit 200 which is hypothesized to be in contact with the upper end of the body 110 to cover the first recess 121 and the second recess 121-1 is formed. .

In addition, the light emitted from the sunlight 700 through the filter unit 200 is the bottom surface (121a) (121a-) of the first and second recesses 121 and 121-1. It is characterized in that it is irradiated to a pair of the first optical sensor 400 and the second optical sensor 400-1, each seated in (1).

At this time, the detection signal for the sunlight 700 detected by the first optical sensor 400 installed in the first recess 121 is the agent for adjusting the balance of the resistance value of the first optical sensor 400. The first position tracking unit 810 provided in the position sensing and tracking unit 800 supplied through the first variable resistor VR1 and the first diode D1, and the second recess 121-1. The detection signal for the solar light 700 detected by the second optical sensor 400-1 may include the second variable resistor VR2 and the second variable resistor for adjusting the balance of the resistance of the second optical sensor 400-1. Characterized in that it comprises a position detection and tracking unit 800 consisting of a second position tracking unit 820 provided in the position detection and tracking unit 800 supplied through the second diode (D2).

Meanwhile, in the present invention, the first optical sensor 400 and the second optical sensor 400-1 may be any one optical sensor holder 100 (100-100) provided as a pair as shown in FIGS. 1 and 2. 1) are respectively installed, the first optical sensor 400 is to detect the light emitted from the sunlight 700 located in the east or south direction, and also the second optical sensor (400-1) Is configured to sense the light emitted from the sunlight 700 located in the west or north direction.

In other words, a solar panel apparatus for generating solar power or a solar panel panel for generating solar power according to the present invention includes a pair of first optical sensors 400 for sensing the solar light 700 located in the east-west direction. ) And a second optical sensor 400-1 are provided in the optical sensor holder 100, and a pair of another first optical sensor for sensing the sunlight 700 located in the north-south direction mentioned above. 400 and the second optical sensor 400-1 may be provided to be used in another optical sensor holder 100-1.

In addition, the first location tracking unit 810 provided in the location detecting and tracking unit 800 includes a first recess for the solar light 700 located in an east or south direction based on the partition 300. The first optical sensor 400 installed at 121 is characterized in that the detection signal is detected that the light emitted from the sunlight 700 is supplied.

In addition, the second position tracking unit 820 provided in the position detecting and tracking unit 800 has a second recessed portion for the sunlight 700 located in the west or north direction based on the partition 300. 121-1), the second optical sensor 400-1 is characterized in that the detection signal is detected that the light emitted from the sunlight 700 is supplied.

In other words, as shown in FIG. 7, the solar light 700 moves eastward or southward in a state where a DC driving power supply 830 is supplied to a position detection and tracking unit 800 called a bridge circuit. In this case, the light emitted from the sunlight 800 is irradiated to the sensing unit 420 of the first optical sensor 400 installed in the first recess 121.

Accordingly, while the resistance value of the first optical sensor 400 decreases, for example, a light-on type operation is performed, and as shown in FIG. 7, the first optical sensor 400 passes through the first optical sensor 400. As a result, the current (i1) flowing increases, and as a result, a detection signal converting a light (or 'light') signal into a current signal is generated, thereby generating sunlight 700 located in the east or south direction. The sensing operation will be made.

Subsequently, when the detection signal sensed by the first optical sensor 400 is supplied to the first position tracking unit 810, a driving motor (not shown) separately provided in the first position tracking unit 810 is omitted. By activating, a solar panel (not shown) that produces solar power or a heat collecting plate (not shown) that produces solar heat performs a position tracking operation toward the solar light 700.

Here, reference numerals R1 and R2 indicated in FIG. 7 as a reference are resistors, and the configuration and operation for tracking the partially described solar light 700 are not essential concepts of the present invention, and Detailed description will be omitted to avoid confusion with the present invention.

Meanwhile, as shown in FIGS. 1 and 2, a second optical sensor 400-installed in another optical sensor holder 100-1 located in a west or north direction in which a shadow is generated due to the partition 300. In 1), since the light emitted from the sunlight 700 is not irradiated, a change in the resistance value of the second optical sensor 400-1 (for example, a 'decrease' of the resistance value) As a result, as shown in FIG. 7, the current i1-1 passing through the second optical sensor 400-1 does not flow, and as a result, a detection signal is transmitted to the second position tracking unit 820. It will not be supplied.

In other words, because the sunlight 700 is not located in the above-mentioned west or north direction, this prevents the sensing operation of the sunlight 700 from the second light sensor 400-1. Position tracking operation for the sunlight 700 is also not made.

On the other hand, the filter unit 200 is a 'b' shape formed along the outer periphery of the filter unit 200 in the 'b' shaped first bent portion 123 formed on the upper end of the body 110 The second bent portion 223 of the shape is characterized in that the hypothesis (加 設) without flowing in contact with each other.

In this case, it is preferable to fix the first bent portion 123 and the second bent portion 223 by a separate bonding means so that rain water and dust do not flow from the outside.

In addition, the filter unit 200 is formed of any one of a flat surface or convex shape, the light emitted from the sunlight 700 is filtered (transmitted) in the range of 5% to 95% transmittance (Filtering) transmission It is characterized by consisting of translucent body as possible.

In addition, the filter unit 200 is similarly made of any one of a flat surface or convex shape, such as sunglasses (Sunglass) is colored on the surface of the filter unit 200, such as nickel, chromium, cerium, etc., It is characterized by consisting of a photosensitive member that absorbs the light emitted from the sunlight 700 to reduce the transmittance.

The reason why the filter unit 200 is used as a translucent body or a photosensitive member is as follows: a strong weather intensity of the light emitted from the sunlight 700 or a large amount of irradiated light is emitted. The second optical sensor installed in the first optical sensor 400 and the second groove 121-1 installed in the first recess 121 in the range (for example, illuminance of 10,000 lx or more). In order to increase the sensitivity for detecting the sunlight 700 in the 400-1).

In other words, if the filter unit 200 is made of a transparent body through which 100% of light passes completely, as described above, the intensity of light emitted from the sunlight 700 is very strong. In addition, in the illuminance range in which the amount of irradiated light is too large, shadows are generated on either side of the first light sensor 400 or the second light sensor 400-1 by the partition wall 300. Even though the light sensor holder 100 (100-1) surroundings are relatively too bright, the self-resistance values of the first optical sensor 400 and the second optical sensor 400-1 are both 0? This may result in a detection error.

5 and 6, the first optical sensor 400 installed in the first recess 121 and the second optical sensor 400-1 installed in the second recess 121-1. The straight portions 421a and 421a-1 of the sensing lines 421 and 421-1 generated in the sensing units 420 and 420-1 of FIG. 2 are installed in parallel with the partition wall 300 to thereby be installed. It may be desirable to uniformize the light irradiated from the sunlight 700 to the sensing lines 421 and 421-1 so that the sensing operation can be performed more easily.

In addition, the partition 300 is inserted through a cutout 210 formed in a rectangular shape in the center of the filter unit 200 as shown in FIGS. 4 and 5, and the body 110. It is characterized in that the fastening grooves 171, 172 (172-1) formed in succession to a predetermined depth and width on the bottom surface (121a) (121a-1) and the side of the inner center portion of the.

In this case, the partition 300 is preferably made of a metal material or synthetic resin of an opaque material because the shadow must be completely generated by the sunlight 700.

In addition, the partition 300 is installed in consideration of its size so that sufficient shadow can be generated in the filter unit 200 hypothesized by the sunlight 700 at the upper end of the body 110. Would be preferred.

On the other hand, the partition 300 is that the light emitted from the sunlight 700 is reflected or scattered in the interior of the first groove portion 121 and the second groove portion 121-1. In order to prevent this, as shown in FIG. 2, light is easily absorbed by the partition wall 300a of the portion entering the first recess 121 and the second recess 121-1 through the filter 200. Using a material composed of any one of black or black gradations, or on the surface of the partition 300a mentioned above, a black or black gradation that is easy to absorb light, as mentioned above. Iii) characterized in that the material consisting of any one of the coating (Coating) or coating treatment.

In addition, the first recess 121 and the second recess 121-1 also emit light emitted from the solar light 700 to the first recess 121 and the second recess 121-1. In order to prevent reflection or scattering in the interior, the first groove portion 121 and the second groove portion (including the bottom surface 121a, 121a-1) as shown in FIG. 121-1) is characterized by consisting of coating (coating), coating the material consisting of any one of black or black-based gradation that is easy to absorb light on the surface.

Of course, the body 110 provided in the optical sensor holder 100 (100-1) also in order to prevent the light emitted from the sunlight 700 is reflected or scattered (light), It may be desirable to construct a material made of any one of black or black gradations that are easy to absorb.

1 and 2, a first optical sensor 400 and a first optical sensor 400 and a second fixing groove 122-1 are provided on the lower portion of the body 110. It is characterized in that the cap (500) (500-1) for fixing the two light sensor (400-1) is firmly inserted.

At this time, the first fixing groove 122 and the second fixing groove 122-1 should not allow the transmission of light from the outside to the first optical sensor 400 and the second optical sensor 400-1 side. In particular, it may be preferable to bond the epoxy with silicon or the like so that rainwater does not flow in, and fix the same firmly.

Here, reference numerals 511 and 511-1 indicated in FIG. 1 as reference are lead lines 411 provided in the first and second optical sensors 400 and 400-1. 411-1 is a through hole.
