FIG. 1 is a perspective view showing a solar LED lighting apparatus according to an embodiment of the present invention. FIG. 2 is a view showing a state of coupling between an LED substrate and a cover according to an embodiment of the present invention. 1 is a block diagram illustrating an internal configuration of a solar LED lighting apparatus according to an embodiment;

Referring to the drawings, a solar LED lighting apparatus 10 according to the present invention includes a solar panel 40 and an LED module 20, wherein the solar panel 40 is configured to convert sunlight into electric energy The solar panel 40 according to the present invention comprises an electricity generation panel 41 for generating electric energy from sunlight and a current detection panel 42 for detecting the amount of generated electric energy.

Here, the electricity generating panel 41 receives light from the sunlight to generate electricity. The generated electric energy is charged through the charging circuit 50, and the charged electric energy is then transmitted to the LED module 20 And lighting is performed.

In addition, the current detection panel 42 is provided to measure the current intensity of the electric energy generated when the light is received from the sunlight.

The intensity of the light is utilized for on / off control for turning on or off the LED 30 through the control unit 30. The controller 30 according to the present invention can greatly enhance the efficiency of the LED 30, The sunrise / sunset time according to latitude and longitude can be pointed out and turned off through the latitude and longitude information where the LED lighting apparatus 10 is located, and the amount of current detected through the current detection panel 42 And determines whether the current light is turned on or off when it is lower or higher than a predetermined set current amount.

First, explain the process of point and turn off according to sunrise / sunset time through latitude and longitude information.

A latitude and longitude input unit 90 for inputting latitude and longitude information corresponding to the installation position, an RTC clock 100 for receiving time information, and an RTC clock 100 And a control unit 30 for calculating sunrise and sunset time information for each installation position of the solar LED lighting apparatus 10.

The control unit 30 calculates the sunrise and sunset time information for each installation location of the solar LED lighting apparatus 10 by reading the time from the RTC clock 100. The control unit 30 controls the sunset, (70) and (80), and the point is turned off at the correct time.

Of course, the controller 30 stores the sunrise and sunset times according to latitude, longitude and date.

In addition, the control unit 30 receives the latitude and longitude of the area where the streetlight is installed through the latitude / longitude input unit 90 from the user.

Then, the RTC clock 100 outputs the current date data and the current time data, thereby obtaining the current date data and the current time data.

Therefore, the control unit 30 invokes the sunrise / sunset storage time by latitude / longitude using the data from the latitude / longitude input unit 90 and the RTC clock 100, and calculates the sunrise and sunset time and the current time data The solar LED lighting apparatus 10 is blinked as a basis.

On the other hand, when the latitude and longitude are stored in advance in the control unit 30, only the corresponding cities such as Seoul, Busan, Daegu, Gwangju, Incheon, Daejeon, Suwon, Ulsan, And it is automatically turned on / off according to the sunset sunrise time.

The control unit 30 may perform on / off control of the LED module 20 through the amount of current detected from the current detection panel 42. The current detection panel 42 includes a plurality of current detection panels 42, .

The current detection panel 42 shown in FIGS. 1 and 2 is preferably positioned at the edge of the solar panel 40 and at the center of each corner so that each current detection panel 42 is widely distributed.

Accordingly, the control unit 30 detects each current amount of the plurality of current detection panels 42, calculates the average current amount thereof, compares the current amount with the set amount of on or off set current, .

This is because the current amounts of the entire current detection panel 42 are summed up for more accurate current amount detection, and the average current amount is calculated by dividing the total number and compared with the set current amount for lighting or off, .

The current amount of any one of the current detection panels 42 is set to 10% or more of the average current amount of the remaining current detection panels 42 in case that the specific current detection panel 42 is damaged or an error occurs when the average current amount is calculated. Or more of the average current amount is excluded in the calculation of the average current amount.

The control unit 30 also stores the detected current amount characteristic table with respect to the use time of the current detection panel 42 when specifying the set current amount as the detected current amount gradually decreases according to the use time of the current detection panel 42 , It is preferable to count the use time of the current detection panel 42 and to specify the set current amount corresponding to the use time.

That is, even if the same light is irradiated to the current detection panel 42 as it is used for a long period of time, the amount of current detected is gradually reduced. The distribution curve of the detected current amount with respect to the use time is stored in the control unit 30, With reference to the distribution curve.

In this way, the control unit 30 controls the turning on / off of the solar LED lighting apparatus 10 based on the latitude and longitude and the sunset / sunrise time designated by the date, or controls the current detection panel 42 of the solar panel 40 It is preferable to set it so that it is turned on or off when it satisfies any one of the two conditions.

Thus, when there is no shade or no clouds, the point is turned off by the latitude and longitude and the sunset / sunrise time by day, but when the lightness is decreased due to the shadow or cloudy clouds, the latitude and longitude and the sunset / The light is emitted a little earlier and the light is turned off a little later, so that it is suitable for the installation environment and can be controlled to go out.

In addition, the LED module 20 may further include a transparent cover 60 as shown in FIG.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to those precise embodiments, and many alternatives, modifications, and variations will be apparent to those skilled in the art. I will understand.

Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
