The technical problems achieved by the present invention and the practice of the present invention will be more clearly understood by the preferred embodiments of the present invention described below. The following examples are merely illustrated to illustrate the present invention and are not intended to limit the scope of the present invention.

1 is a schematic diagram showing the overall configuration of a winker light using a solar cell according to the present invention.

As shown in FIG. 1, the winker light using the solar cell according to the present invention includes a solar panel 10 and a battery, and is charged at night after charging the battery with the power of the solar panel 10 during the day. A power supply control box 20 for supplying power to the LED, a plurality of high brightness LED lamps connected in a line in a transparent PVC tube, a light emitting hose 40 indicating a hazardous area, a power supply control box 20 and a light emitting hose ( 40 is connected to the connector 30, the light emitting hose 40 is respectively provided and consists of a PCB (50) containing an optical sensor for automatically controlling the operation of the light emitting hose by detecting light.

Referring to FIG. 1, the solar panel 10 is attached to one surface of the power supply control box 20 to convert solar energy into electrical energy and provide the power supply control box 20. The power supply control box 20 charges the battery (NI-MH 2.4V 3000mAh) with the electric energy of the solar panel 10 and provides the power of the battery to the light emitting hose 40 at night. In the embodiment of the present invention, the power supply control box 20 is to be connected to the light emitting hose 40 of the 10m length to both sides can be in charge of a total of 20m,

The light emitting hose 40 is connected to 24 high-brightness LEDs in a 10 m long transparent PVC tube in a line and is connected to a power supply control box 20 through a connector 30. The hose used in the present invention has excellent transparency and is characterized by excellent night visibility. In addition, each light emitting hose 40 is provided with a PCB (50) including an optical sensor to automatically operate and stop according to the installation position of the hose.

FIG. 2 is a block diagram illustrating a detailed configuration of the PCB 50 including the optical sensor shown in FIG. 1, and FIG. 3 illustrates a specific circuit of the PCB 50 including the optical sensor according to the present invention. It is a circuit diagram.

PCB 50 including the optical sensor of the winker light using the solar cell according to the invention is supplied with a power from the solar panel 10 as shown in Figure 2 to the battery built in the power supply control box 20 When the battery and the charging unit 21 to charge, the light sensor unit 23 for detecting the presence or absence of light, and the light sensor unit 23 detects light (that is, during the day), the power is shut off and there is no light (that is, LED at the flip-flop unit 25 and the flip-flop unit 25 to generate the LED flashing signal according to the oscillation signal of the oscillation unit 24 when the power is supplied. It is composed of an output control unit 26 for transmitting a flashing signal to the light emitting unit (42). The light emitting unit 42 is high brightness LEDs installed in the light emitting hose 40, and when the LED blinking signal is transmitted from the output control unit 26, the light emitting unit 42 flashes accordingly to indicate a dangerous area or a construction area.

Referring to the operation of the winker light of the present invention in detail with reference to the circuit of Figure 3 as follows.

During the day, the solar panel 10 converts solar energy into electrical energy to charge the battery through the diode D1 of the charging unit 21. In addition, when light is detected during the day, the photo transistor Q3 of the light sensing unit 23 is turned on so that the collector of the Q3 transistor is low. Accordingly, a reverse bias is applied to the Q2 transistor to turn off the Q2 transistor, thus supplying power. Since the FET Q1 of the control unit 22 is cut off and power cannot be supplied to the flip-flop IC U1, the LED of the light emitting unit 42 does not blink.

At night, the photo transistor Q3 of the light sensing unit 23 is turned off, and the collector of the Q3 transistor becomes high. Accordingly, a forward bias is applied to the Q2 transistor so that the Q2 transistor is turned on, and thus, the power supply control unit 22 FET Q1 is turned on to supply battery power to the flip-flop IC (U1). The flip-flop IC U1 oscillates at a frequency determined by the time constant of the resistor R3 connected between the osc1-osc2 terminals and outputs an LED blink signal to out1 and out2 to flash the LEDs of the light emitting unit 42.

As described above, according to the present invention, the battery is charged by the solar panel 10 during the day, and at night, the photo transistor Q3 is turned off and the FET transistor Q1 of the power supply controller is turned on to turn the battery on the flip-flop IC U1. Power supply of the, and the flip-flop IC (U1) generates a LED flashing signal to flash the high-brightness LED installed in the light emitting hose 40 to indicate a construction area or a dangerous area.

The winker light of the present invention can be operated at low voltage and low current so that two light emitting hoses can be operated at the same time, and can be used for three or more consecutive days when charged once, and can be used for seven or more days when using only night.

The present invention has been described above with reference to one embodiment shown in the drawings, but those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
