Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art may easily implement the technical idea of the present invention.

The street lamp according to the present invention is implemented with a small number of light emitting diodes by transmitting the emitted light through the convex lens. Therefore, the street lamp of the present invention can reduce the heat problem.

1 is a block diagram showing a first embodiment of a street lamp according to the present invention. Referring to FIG. 1, the street light 10 includes a light collecting unit 11, a storage battery 12, a switch circuit 13, a detector 14, a light emitting unit 15, and a light emitting case 16.

The light concentrator 11 receives sunlight and generates a current according to the input sunlight. The generated current is transmitted to the storage battery 12. The light collecting unit 11 may include a plurality of solar cells SCELL1 to SCELL8.

Here, a solar cell is a semiconductor device that directly converts solar energy into electrical energy. When light of energy larger than the prohibited band is irradiated to the semiconductor junction region having the PN junction surface, conduction band electrons of the p-type semiconductor are excited to a valence band by the incident light energy. The excited electrons generate one electron hole pair in the p-type semiconductor. The electrons in the electron-hole pairs thus generated are transferred to the n-type semiconductor by an electric field existing between the p-n junctions, and thus current is supplied to the outside. Such solar cells may be crystalline silicon solar cells, amorphous solar cells, CIS cells, GaAS solar cells, CdTE solar cells, and the like.

The light collecting unit 11 illustrated in FIG. 1 includes eight solar cells SCELL1 to SCELL8. However, the present invention is not necessarily limited thereto. The light collecting part according to the present invention includes at least one solar cell.

The storage battery 12 receives electric current generated from the light condenser 11 and stores electric power. The storage battery 12 may be a lead storage battery, a Redox-Flow battery, a NaS battery, or the like. The storage battery 12 may be supplied with power from a separate power supply device (eg, a battery, a conventional power supply line), although not shown, when fully discharged. Meanwhile, the storage battery 12 may further include a charge blocking device (not shown) so as not to be charged above a predetermined power value.

The switch circuit 13 electrically switches between the battery 12 and the light emitting unit 15 in response to the sensing signal. The sense signal is here generated from the detector 14. For example, when a detection signal corresponding to illuminance below a predetermined value (night) is input, the switch circuit 13 electrically connects the storage battery 12 and the light emitting unit 15. As a result, the light emitting unit 15 may be supplied with power from the storage battery 12. On the other hand, when the detection signal corresponding to the illumination intensity larger than the predetermined value (day) is input, the switch circuit 13 electrically cuts off the battery 12 and the light emitting portion 15.

The detector 14 generates a detection signal by detecting whether the illuminance of the incoming sunlight is equal to or greater than a predetermined value. The detector 14 may be implemented with at least one photodiode. Here, the photodiode generates a corresponding voltage according to the input sunlight. The sense signal is determined by the voltage level generated. Although not shown, the detector 14 may be implemented inside the light collecting unit 11.

The light emitting unit 15 may be located at the bottom of the light collecting unit 11. The upper end of the light collecting part 11 is where sunlight is incident. The light emitting unit 15 generates light by using power supplied from the storage battery 12. The light emitting unit 15 includes a plurality of light emitting diodes LED1 to LED8.

The light emitting case 16 integrates and transmits the light generated from the light emitting unit 15. The light emitting case 16 may be implemented with glass or transparent plastic. In particular, the light emitting case 16 according to the present invention may include a convex lens 16_2. The convex lens 16_2 focuses the light generated from the light emitting diodes LED1 to LED8 into one focal point. The convex lens 16_2 may increase illuminance by condensing from the light emitting diodes LED1 to LED8.

The street lamp 10 according to the present invention may collect light generated from the small number of diodes LED1 to LED8 through the block lens 16_2. As a result, the street lamp 10 of the present invention may generate light having good characteristics by using a small number of diodes.

At this time, the position of the focus P may be set to be below the ground. The position of the focal point P is determined by the distance from each of the light emitting diodes LED1 to LED8 to the convex lens 16_2, the refractive index of the medium between the convex lens 16_2 to each of the light emitting diodes LED1 to LED8, and the lens. It is determined by the refractive index of.

The position of the focal point P shown in FIG. 2 is set below the ground. However, the focus of the present invention is not necessarily limited thereto. The focus of the invention may be set on the ground.

Each of the plurality of groups 100, 200, 300 includes a plurality of street lights. Here, each street light includes any one of the street lights 10 and 20 shown in FIG. 1 or 3. In addition, each street light includes a transceiver that transmits whether the street light is turned on through the wireless communication to the next street light. Such a transceiver wirelessly transmits a lighting signal indicating whether the streetlight is lit to the transceiver of the next street lamp.

In addition, at least one street light (180, 280, 380) of each group (100, 200, 300) communicates with the control room 400 with respect to the operating state of each of the groups (100, 200, 300) through a network communication network. Here, the network communication network may be a communication network such as the Internet, a wireless communication network, an RF wireless communication, and the like operated only by a communication company.

 Each group shown in FIG. 5 includes eight street lights 110-180. However, the group of the present invention is not necessarily limited thereto. The group of the present invention may include at least two street lights.

The following describes how the street light operation status of the first group 100 is managed. The first transceiver 112 of the first street light 110 determines whether the first street light 110 is turned on in response to the remote control signal of the control room 400. Here, the first transceiver 112 is implemented to receive a control signal from the control room 400 through wireless communication.

If the first street light 110 is turned on, the first transceiver 112 transmits a lighting signal to the second transceiver 122 of the second street light 120. On the other hand, if the first street light 110 is not lit, the first transceiver 112 does not transmit the lit signal to the second transceiver 122.

The second transceiver 122 of the second street light 120 receives a lighting signal from the first transceiver 112 and determines whether the second street light 120 is turned on. If the second street light 120 is turned on, the second transceiver 122 transmits a lighting signal to the third transceiver 132 of the third street light 130. On the other hand, if the third street light 130 is not turned on, the second transceiver 132 does not transmit the lighting signal to the third transceiver 132.

As described above, each transceiver transmits a lit signal to indicate whether it is lit or not to the next transceiver. Finally, the eighth transceiver 182 of the eighth street light 180 receives the lighting signal from the seventh transceiver 172 and determines whether the eighth street light 180 is turned on. If the eighth street light 180 is turned on, all of the street lights 110 to 180 of the first group 100 are turned on. Therefore, the eighth transceiver 182 transmits a signal indicating that all the street lights of the first group 100 are turned on to the control room 400. Here, the eighth transceiver 812 is implemented to transmit a signal to the control room 400 through wireless communication.

As described above, the second group 200 and the N-th group 300 are also managed in the same manner as the street lamp operating state of the first group 100.

The number of groups shown in FIG. 5 is three. However, the number of groups of the present invention need not be limited thereto. The number of groups of the present invention is at least one.
