It is configured to drive the light emitting unit configured with the light emitting diodes, and to diffuse the light emitted from the light emitting unit to the diffusion surface to propagate light to a wider space.

However, the conventional solar-embedded light emitting device having the above configuration simply charges the electric energy output from the solar cell which converts solar light energy into electrical energy during the day to a rechargeable battery, which is a secondary battery, and the electricity charged in the storage battery at night. It is configured to drive the oscillation unit as energy to flash the light emitting unit consisting of a plurality of LEDs in a specific pattern.

The general rechargeable battery has been widely used as an electric storage device of solar cells because of its high energy density of 20 to 120 Wh / kg and the ability to repeatedly discharge and charge the battery, but the charge and discharge characteristics are limited to 1000 cycles. There was a hassle to replace the new one after a certain period of use. In addition, the solar buried light emitting device described in the above patent document could not control the flashing pattern of the LED light emitting part from the outside. That is, the conventional solar light is manufactured in a sealed form so that rainwater does not penetrate into the interior and is buried, and thus, the flashing pattern of the solar light cannot be changed from the outside.

In the solar light 10 configured as shown in FIG. 2, a process of charging and discharging a voltage between the supercapacitor 16a and the battery 16b will first be described.

In the daytime, the solar cell 14 converts the light energy of the sun into electrical energy (Solar_V) and outputs it. Since this electric energy (Solar_V) is a light energy conversion, it is generated only during the day, and at night the level is zero volts (0V). When the electric energy Solar_V is normally output, the supercapacitor 16a and the battery 16b charge each of them. That is, during the day, the battery is charged, and at night, the charged capacitor discharge voltage CAP-V and the battery discharge voltage BAT_V are output.

Decide For example, when the electric energy Solar_V is output at a predetermined level or more, for example, when the voltage is 0.7 volts or more, it is recognized as a charging mode and outputs the capacitor discharge voltage CAP-V and the battery discharge voltage BAT_V. By blocking all of them so as not to discharge, the electric energy (Solar_V) output from the solar cell 14 is continuously charged to the supercapacitor 16a and the battery 16b.

If there is no voltage of the electric energy solar_V, the capacitor discharge voltage CAP_V output from the supercapacitor 16a is given priority to be output as the driving voltage VDD of the light emitting unit 18, and the capacitor discharge voltage. When the level of CAP_V falls below 0.7 volts, the battery discharge voltage BAT_V output from the battery 16b is supplied to the driving voltage VDD of the light emitting unit 18. When the voltage level of the battery discharge voltage BAT-V falls below 0.7 volts, the output of the battery discharge voltage BAT_V is cut off to protect the battery 16b.

The light emitting unit 18 in the solar light 10 operated by the driving voltage VDD as described above blinks by the light emission control unit 15 that receives the data packet transmitted from the remote controller 20 and controls the blinking of the corresponding LED.

In the case of transmitting the data packet including the LED abnormality detection signal ED from the light emitting unit 18 to the remote controller 20, the unique packet includes its own identification code.

On the other hand, the remote control 20 for transmitting and receiving data to and from the light emission control unit 15 of the solar light 10 includes a memory 22, which stores a plurality of flashing pattern information as shown in FIG. A keypad (24) for selecting any one of a plurality of unique patterns for selecting one of the plurality of solar lights (10) and a plurality of flashing patterns stored in the memory (22); RF transceiver 1 (11) in the solar light (10) in the solar light 10 through the 2 (21) to the RF packet by reading the unique information and the flashing pattern information corresponding to the information output from the keypad from the memory 22 A remote control controller (MCU) 23 for receiving a data packet transmitted from the light emission controller of the solar light 10 through the RF transceiver 2 21 and displaying the state on the LCD display 25.

The MCU 12 of the solar light 10 configured as shown in FIG. 2 reads the parameters in step S12 after initializing in step S11 of FIG. 4. That is, the data packet is received through the RF transceiver 1 (11) and stored in the memory 22. Thereafter, the MCU 12 reads the data packet stored in the memory in step S13 to analyze the emission color and the pattern, and generates driving data of the pattern analyzed in steps S14 to S17. For example, after generating a color to be turned on and a flashing cycle (for example, 1 second on), the pattern data generated in step S18 payloads to the LED flashing control unit (13).

At this time, the LED flashing control unit 13 selectively switches the switches of the driver SW according to the payloaded pattern data, that is, the color and the flashing period, so that the red, green, and blue LEDs 18a, 18b, 18c). The technique of controlling the color by controlling the red, green, and blue LEDs 18a, 18b, and 18c is obvious to those skilled in the art, and thus a detailed description thereof will be omitted.

In step S20, the red, green, and blue LEDs 18a, 18b, and 18c are controlled to selectively drive switches of the driver SW connected to the red, green, and blue LEDs 18a, 18b, and 18c to emit corresponding colors. One MCU 12 searches for whether the timer has exceeded the set flashing period. For example, if the set flashing period is 1 second, as soon as the lit time exceeds 1 second, the process jumps to the above-described step S13, reads the data packet stored in the memory 22, and analyzes the corresponding light emission color and pattern to perform the above-described process.
