Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

The present invention relates to a lighting device using a solar cell with a burglar alarm function, and to a lighting device using a solar cell enhanced security by adding a burglar alarm function while being easily installed and removed in a garden without a power line. It is about.

Lighting device using a solar cell added to the burglar alarm function according to the present invention, the buried fixing part 20 and the support portion which is connected to one end of the support portion 10 and the support portion 10 installed on the ground and embedded in the ground A solar cell 40 and a cover part which are connected to the other end of the 10 and are attached to one side of the cover part parallel to the ground and the cover part 30 to convert sunlight into electrical energy. 30, the lighting unit 50 attached to the other surface, the battery unit 60 for storing electrical energy generated by the solar cell unit 40, and the theft alarm unit 70 for alarming theft notification when a theft signal is generated. Include.

1 illustrates an embodiment of a lighting apparatus using a solar cell to which the burglar alarm function is added according to the present invention. Referring to FIG. 1, a lighting apparatus using a solar cell to which the burglar alarm function is added will be described.

As shown in FIG. 1, the support 10 is installed vertically from the ground, and the embedding fixing portion 20 is connected to one end of the support 10 and embedded in the ground. In addition, the solar cell unit 40 and the cover unit 30 which are vertically connected to the other end of the support unit 10 and attached to an upper surface of the cover unit 30 parallel to the ground to convert sunlight into electrical energy. The lighting unit 50 attached to the lower surface of the) and the battery unit 60 for storing the electrical energy generated by the solar cell unit 40. Although the battery unit 60 and the burglar alarm unit 70 are not illustrated in FIG. 1, it will be described again below.

In addition, the end of the buried fixing portion 20 is formed to be pointed to be pointed to the ground 100, the cross section may be wider as it comes to the other end coupled to the support 10. By providing the shape of the long nail in this way there is an advantage that the insertion and removal from the ground is easy. However, it is easy to insert and remove, but when the lighting device is large or heavy, there is a disadvantage in that the stability to the ground is weak due to weak force.

FIG. 2 illustrates an embodiment of a buried anchor, which can overcome such disadvantages according to FIG. 2. That is, as illustrated in FIG. 2, the plurality of grooves are formed in the buried fixing portion 20 in a spiral manner, so that soil, etc., are formed in the groove 21 when the buried fixing portion 20 is stuck below the ground 100. While filling, the landfill fixing part 20 may be in close contact with soil and the like, and be more firmly and stably buried under the ground. At this time, the shape of the buried fixing portion 20 can be elastically adjusted to increase the fixing force.

On the other hand, a solar cell is a semiconductor device that converts solar energy into electrical energy and has a junction between a p-type semiconductor and an n-type semiconductor, and the basic structure is the same as that of a diode. When sunlight is incident on the solar cell from outside, the conduction band electrons of the p-type semiconductor are excited as valence bands by the incident light energy, and the excited electrons generate one electron-hole pair inside the p-type semiconductor. The electrons of the generated electron-hole pairs are transferred to the n-type semiconductor by an electric field existing between the pn junctions to supply current to the outside.

Products using these solar cells are easy to install because they do not require a separate wire, which is necessary for ordinary electric products, and are pollution-free because they operate with solar energy, and there is no electric charge because unlimited solar energy is available everywhere. And so on.

Therefore, the lighting apparatus according to the present invention attaches such a solar cell to the upper surface of the cover portion 30 to convert sunlight into electrical energy, the electrical energy converted by the solar cell unit 40 is the battery unit 60 ) Is stored. In addition, the lighting unit 50 may include at least one LED lamp, and the LED lamp may be used as a light emitting source by using the electrical energy converted through the solar cell unit 40.

In this case, the solar cell of the solar cell unit 40 uses a CIS-based solar cell instead of the conventional crystalline silicon solar cell. CIS solar cell is a solar cell coated with I-III-IV chalcopyrite compound semiconductor represented by copper-indium selenium (CuInSe), and CIS system has a direct transition energy band of 1 eV or more. It is a low-cost, high-efficiency solar cell that has the highest optical absorption coefficient among semiconductors and is highly optically stable, which can dramatically improve the economics of photovoltaic power generation. In this case, indium (In) may be partially or entirely substituted with gallium (Ga) or aluminum (Al), and selenium (Se) may be partially or entirely substituted with sulfur (S).

That is, the conventional crystalline silicon solar cell is weak to the increase in cost and strong wind by using a solar tracking device, the CIS-based solar cell can generate a sufficient amount of power even without a solar tracking function and the cost can be lowered.

Thus, in the present invention, by using a CIS-based solar cell instead of the conventional crystalline silicon solar cell, even if the amount of sunlight is weak, it is possible to store more electricity than the conventional crystalline silicon solar cell. Therefore, in the present invention, the solar cell unit 40 can be installed substantially horizontally on the ground by accumulating enough electricity even when the amount of sunshine is weak using the CIS solar cell.

In addition, in the present invention, by using a CIS-based solar cell to store enough electricity even when the amount of sunshine is weak, it is possible to reduce the production cost of the lighting device without using a separate solar tracking device, and to withstand strong winds better.

3 illustrates an embodiment of a lighting apparatus using a solar cell to which the burglar alarm function is added according to the present invention. Referring to FIG. 3, an embodiment of a lighting apparatus using a solar cell to which the burglar alarm function is added is described. Explain.

First, although the support 10 is shown in a cylindrical shape in FIG. 3, the present invention is not limited thereto and may be changed in various forms such as a circle, an ellipse, a cube, and the like.

In addition, if the solar cell unit 40 attached to the upper surface of the cover portion 30 is horizontal with respect to the ground, the shape around the cover portion 30 may be shaded as shown in FIG. It is possible and various design changes are possible. In addition, as described above, the solar cell unit 40 may be a CIS solar cell.

In addition, the battery unit 60 may be located between the cover unit 30 and the lighting unit 50, and although not shown, may be located inside the support unit 10.

On the other hand, the burglar alarm unit 70 includes a motion detector for detecting the movement of the lighting device itself or the movement within a predetermined distance from the lighting device, the motion detector generates a burglar signal when the movement is detected.

When the theft signal is generated, the burglar alarm unit 70 alarms the burglar notification, the burglar alarm unit 70 is a method of alerting the burglar alarm, audible alarm system using an alarm, a message for transmitting a message to a predetermined telephone number It may be at least one of a transmission method and a telephone connection method of playing a pre-stored content by calling to a predetermined telephone number such as 112. In addition to the audible alarm system, the burglar alarm unit 70 should have a built-in communication module, and can be changed in various forms in addition to the above-described method. 3 illustrates an example of alarming the theft notification in the form of an audible alarm using the speaker 77.

Lighting device according to the invention is easy to install but also easy to remove the risk of theft. This is especially true because there is no electrical connection because of the use of solar cells. Therefore, when the lighting device is moved to approach the lighting device or to remove the lighting device from the ground, theft alarm is generated by generating a theft signal. Accordingly, the motion detector includes at least one of a motion sensor, a horizontal sensor, and a distance sensor to detect the lighting device itself or movement around the lighting device to prevent theft.

However, whenever a dog or cat raised at home approaches the lighting device, the theft alarm sounds as well as the noise, and it is inconvenient to release the theft alarm every time. Therefore, it is desirable to prevent the alarm when a pet or a child approaches by installing a reclamation fixing part 20 deeply below the ground so that the pet or a child does not tilt even when riding a joke. .

In addition, as in the case where a dog or a cat in the house approaches the lighting device, even when the location of the lighting device is moved, it is inconvenient because the burglar alarm sounds as well as the burglar alarm must be released each time. Accordingly, the present invention is provided with an alarm setting unit 80 to receive a password from the user to set whether or not the operation of the burglar alarm unit 70.

4 illustrates an embodiment of a lighting apparatus using a solar cell to which a burglar alarm function including an alarm setting unit is added. When the alarm setting is released in the alarm setting unit 80 as shown in FIG. Even though the alarm does not sound. In addition, even if the alarm setting is not released, that is, even when the alarm setting unit 80 is configured to operate the burglar alarm unit 70, when the burglar signal is generated, the password inputted from the alarm setting unit 80 and preset If the passwords match, the alarm notification may be stopped by releasing the operation of the burglar alarm unit 70. As such, even when the alarm is set, convenience can be increased by allowing the alarm to be stopped by inputting a password as necessary.

FIG. 5 illustrates an embodiment of a lighting apparatus using a solar cell having a burglar alarm function provided with a housing. As illustrated, the present invention transmits and receives a signal at a distance separated from the buried fixing part 20. As shown in FIG. It may further include a housing (90).

The housing 90 is embedded below the ground and is not visible from the outside. Therefore, when the lighting device is removed, the lower end of the buried fixing portion 20 passes through the upper end of the housing 90, at which time signals can be transmitted and received to generate theft signal, thereby effectively notifying theft.

Accordingly, the housing 90 includes an RFID reader 91, the buried fixing portion 20 includes an RFID tag 92, and the RFID reader 91 recognizes the RFID tag 92. In this case, the theft signal is generated to notify the theft of the theft alarm unit 70.

Radio-Frequency IDentification (RFID) is an automatic identification technology (AIDC) that uses radio frequency to identify tags attached to objects and process desired information without direct contact. RFID technology provides fast recognition speed, long recognition distance, most obstacle penetrating functions except metals, and excellent usage time and data storage capability, so even if there is dirt under the ground, it can transmit and receive signals using radio frequency. There is an advantage.

RFID is also used to recognize information over long distances using radio waves and to identify the tagged object. In other words, it performs a function similar to a barcode. Therefore, in the case of using RFID, when installing a plurality of lights in a certain space can be identified by the lighting device, there is an advantage that the location of the stolen lights can be quickly known when theft occurs. In particular, such an effect may be maximized when the burglar alarm 70 performs the host computer role of the RFID system. Therefore, when the burglar alarm 70 serves as a host computer, the RFID reader 92 converts the received radio wave into digital information and transmits it to the burglar alarm 70, and the burglar alarm 70 In addition to alerting you to theft, you may also be informed of the location or information of the stolen lighting device in a message or sound.

RFID is classified into a passive type and an active type according to a method of obtaining an energy source of radio waves transmitted by a tag. The passive type obtains the transmit energy from the radio waves received from the reader, and the active type obtains the transmit energy from the internal battery. Passive tags are therefore battery-free, suitable for short-range communications within 10 m, inexpensive, and have a semi-permanent lifetime. Active tags, on the other hand, have a built-in battery in the tag that allows for tens of meters of remote communication, but they are expensive and have a limited lifetime. Therefore, the RFID used in the present invention preferably uses a passive type.

Meanwhile, instead of using RFID, the housing 90 allows the housing 90 and the burglar alarm unit 70 to perform wireless communication at predetermined time intervals, and when the distance measured by wireless communication is far more than a predetermined distance. Theft signal can be generated by recognizing that theft has occurred.

Accordingly, the housing 90 may include a transceiver for wirelessly communicating with the burglar alarm 70, a distance measuring unit for measuring a distance from the burglar alarm 70 measured by communication between the transceiver and the burglar alarm 70. It may include a signal generator for generating a theft signal when the measured distance deviates from the predetermined reference distance for a predetermined time. The distance measuring unit calculates a communication distance by measuring a transmission speed and time of the wireless communication, and the wireless communication is not limited to the type of wireless communication such as a communication method using an electromagnetic wave as well as a communication method using an electromagnetic wave.

As described above, the alarm setting unit 80 operates when the burglar alarm unit 70 is set to operate. However, when the theft signal is generated, if the password received from the alarm setting unit 80 and the predetermined password match, the operation of the burglar alarm unit 70 can be released or if the password is input in advance, the burglar alarm does not occur. It is desirable to avoid.

6 illustrates an embodiment of the anti-theft alarm, and an embodiment of the anti-theft alarm will be described with reference to FIG. 6. As illustrated, the burglar alarm unit 70 detects theft by remotely transmitting and receiving a signal from the location notification unit 72 and the location notification unit 72 that is detachably mounted to an exterior of the lighting device. The detector 73 may be included. At this time, the position notification unit 72 may be detachably installed as an exterior, but may be embedded in a lighting device, such as the inside of the support unit 10.

The burglar detection unit 73 is measured by a wireless communication with the transceiver unit 74, the transceiver unit 74 and the position notification unit 72 for wireless communication at a predetermined period toward the remote location notification unit 72. And a distance measuring unit 75 for measuring a distance from the position notification unit 72 and a signal generator 76 for generating a stolen signal when the measured distance deviates from the reference distance for a preset time. In this case, if the alarm setting unit 80 is configured to operate the burglar alarm unit 70, the burglar alarm may be released only when a preset password is input when the burglar alarm occurs.

6 illustrates only the configuration of the burglar detection unit, the location notification unit 72 may have the same configuration, and the burglar detection unit 73 and the location notification unit 72 perform only different installation locations. The role is the same. In this way, it is possible to effectively cope by measuring the distance by remotely transmitting and receiving, and notifying the occurrence of theft when moving away from the predetermined distance.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
