That is, the battery unit 400 is configured to charge the electric energy generated from the solar battery unit 300 during the day and to supply the charged electric energy to the lighting unit at night.

For example, the battery unit 400 is charged for 4 to 5 hours during the day, and is supplied with electrical energy to the illumination unit 500 for 10 to 12 hours at night. At this time, the battery unit 400 is configured to charge the solar energy for about 4 to 5 hours without continuously charging the solar energy during the day when the sun is floated.

The heat dissipating unit 530 is provided with a plurality of heat dissipating fins 531. The radiating fins 531 are spaced apart from each other along the periphery of the lighting body 510 and have a large contact area with the outside air.

In this way, the control unit 600 can be controlled from an external device through a communication network. Therefore, the operator can easily control the solar cell street lamp 1000.

For example, an operator installs an app for controlling the solar cell street lamp 1000 on a portable terminal, and then various settings such as the brightness of the lighting of the solar cell street lamp 1000, It can be easily adjusted.

Meanwhile, the solar cell street lamp 1000 may further include a human body sensing unit 700. The human body sensing unit 700 is coupled to a lower portion of the streetlight body unit 200.

The human body detecting unit 700 may include a human body detecting sensor 710 and a fixed frame 720. That is, the human body detection sensor 710 is coupled to the lower portion of the streetlight body 200 by the fixed frame 720 to detect presence of a person around the solar cell streetlight 1000. Here, the fixed frame 720 is formed with an insertion hole 722 so that the human body detection sensor 710 can be inserted into the insertion hole 722.

The human body detection sensor 710 may be a passive infrared ray (PIR) sensor. That is, the human body detection sensor 710 may be configured to detect presence or absence of a person around the solar cell street lamp 1000 by using infrared rays emitted from the subject.

The human body detection sensor 710 may selectively adjust the brightness of the illumination unit 500 according to the presence or absence of a person from the human body detection sensor 710 in conjunction with the control unit 600.

For example, when the human body sensing unit 700 can not recognize the person around the solar cell street lamp 1000 in the evening when the night is dark, the controller 600 is configured to maintain the brightness of the illumination unit 500 at the minimum brightness, When the sensing unit 700 recognizes that the person approaches the solar cell streetlight 1000, the illumination unit 500 may be adjusted to the maximum brightness for 10 to 15 seconds.

5 is a configuration diagram of a solar battery unit according to an embodiment of the present invention.

Referring to FIG. 5, the solar cell unit 300 may include a solar panel 310 and a relay 320. The solar panel 310 is configured to convert light energy emitted from the sun into electric energy.

The solar panel 310 is affected by the solar radiation and generates the power generation voltage V _g . Therefore, in the nighttime without sunlight, the generation amount of the solar panel 310 is minimized, the generation voltage V _g is close to 0V, and the generation voltage V _g generated from the solar panel 310 according to the increase of the solar radiation amount after sunrise .

The relay 320 is instantaneously switched in accordance with the power generation state of the solar panel 310 so as to provide the boosted voltage to the load.

The relay 320 may include a normally closed contact 321, a common contact 322, a constantly open contact 323, and an inductor 324. The common contact point 322 may be connected to the normally closed contact point 321 or may be connected to the normally open contact point 323 according to the strength of the magnetic field generated from the inductor 324.

In other words, when the generated voltage V _g generated by the solar panel 310 flows into the inductor 324 with a voltage value less than a predetermined value, the intensity of the magnetic field generated from the inductor 324 is weak, So that it remains connected to the normally closed contact 321.

Alternatively, when flowing to the power voltage (V _g) predetermined over voltage to the inductor 324, generated in the solar panel 310 becomes larger the intensity of the magnetic field generated from the inductor 324, common contact 322 is NO And is connected to the contact point 323. That is, when the current flowing from the solar panel 310 to the inductor 324 is equal to or higher than a predetermined voltage value, the common contact 322 connected to the normally closed contact 321 is disconnected from the normally closed contact 321, (323). The switching of the connection between the three points of the normally closed contact 321, the common contact 322 and the normally open contact 323 of the relay 320 is referred to as 'contact switching'.

The normally closed contact 321 may be connected to one end N4 of the power setting resistor Rp 330. [ Accordingly, when the normally closed contact 321 is connected to the common contact 322, the current I ₁ flows through the power setting resistor Rp 330. When the connection to the common contact 322 is broken by the switching of the contact The current I ₁ becomes zero.

That is, the current I ₀ flowing through the solar cell 310 = I ₁ + I ₂ And the current I ₀ flowing through the solar cell 310 after the switching of the contacts = I ₂ + I ₃ .

The common contact point 322 is a contact which can be selectively connected to the normally closed contact 321 or the normally open contact point 323 and the common contact point 322 is connected to the one end N2 of the solar panel 310.

The normally open contact point 323 is in an open state that is not connected to the common contact point 322 before the contact point of the relay 320 is changed. The normally open contact point 323 is connected to the common contact point 322 through contact switching and closed. That is, normally, when the relay 320 is disconnected from the common contact 322, when a voltage exceeding a certain level is reached, the contact is switched and connected to the common contact 322.

When the NO contact 323 is a load resistor (R _L), one end is connected to (N5), NO contact 323 after the contact switch 340 is connected to the common contact 322, a load resistance (R _L) The current I ₃ flows through the resistor 340.

Here, the load resistance (R _L ) 340 may be the battery unit 400. In other words, when the generation voltage V _g is generated from the solar panel 310 to a voltage value equal to or higher than a predetermined value, the electric energy generated from the solar panel 310 is charged in the battery unit 400. That is, the battery unit 400 can be charged at a time when a high voltage is generated. Therefore, the battery unit 400 can be charged in a short time, and the service life of the battery unit 400 according to charging and discharging can be extended.

One end N1 of the inductor 324 is connected to the solar panel 310 and the other end N3 of the inductor 324 is connected to the inductor downpressing resistor Rs 350. [ This inductor step-down resistor (Rs) 350 can limit the current flowing in the inductor 324 to protect the relay 320. Here, the current I ₂ flowing in the inductor step-down resistor (Rs) 350 has the same value as the current flowing in the inductor 324.

The free wheeling diode 360 may serve to discharge electrical energy remaining in the inductor 324 to prevent the elements around the inductor 324 of the relay 320 from being destroyed.

The reflux diode 360 is connected in parallel with the inductor 324. One end N1 of the reflux diode 360 is connected to the solar panel 310 and the other end N3 is connected to the inductor downpressing resistor Rs 350. [

In the solar cell street lamp 1000, a solar battery 300 is provided to generate electricity from solar energy to operate the illumination unit 500.
