On the other hand, the switch 153 protrudes to the outside through a hole formed in the case body 152 so that the user can operate on and off by hand. In addition, the case body 152 is provided with a lens hole 143, the lens 142 is mounted, the light of the LED lamp 141 passes through it to brighten the surroundings.

And the case fixing ring 151, the outer periphery of the upper surface has two connection rings that can be fixed by inserting the wires are integrally made to face each other, can be made to hang the hook made of wire.

And the mounting ring is coupled to the outer periphery of the case body, it is configured to support the lampshade at the bottom, it is screwed to the case body outer periphery to easily attach and detach the lampshade.

In the present invention, a general solar cell system that collects sunlight by solar cells and utilizes them as lighting uses conventional techniques. Soon, such a conventional technology, as described in the prior art in Korean Patent Nos. 10-257628 and 10-299947, installs a storage battery between a solar cell and a load, and charges the power generated by the solar cell in the storage battery. It was designed to supply stable power to the load even on rainy days or at night.

The voltage detection unit detects the voltage output from the solar cell and outputs a detection signal to the control unit. The control unit compares the detection signal of the voltage detection unit with a predetermined level inside the predetermined level. If the detection signal is low, the lamp lighting signal is output. That is, when the surroundings become dark, the output voltage of the solar cell is lowered. When the output voltage is lower than the predetermined level, the lamp is switched on. On the contrary, when the detection signal is higher than the predetermined level, the lamp is determined to be sunrise and the lamp is switched off. At this time, it is preferable that the control unit has a protection circuit to prevent overcharging and overdischarging for protection of an auxiliary charging unit such as a capacitor, and maintains the detected output voltage for a predetermined time in order to prevent an instantaneous malfunction of the system. At sunrise, the voltage detector of the solar cell turns off the lamp by outputting a lamp off signal because the detection signal is higher than a predetermined level. Therefore, since the lamp is turned off during the day and the solar cell voltage detector has a lower detection signal than the predetermined level, the lamp is turned on by outputting a lamp lighting signal. Since the voltage detection unit is also conventionally known, detailed description thereof will be omitted.

Therefore, the present invention can continuously supply power by using solar cells, and the lampshade can be easily disassembled and assembled, so that lampshades of various designs can be installed, and after removing the lampshade for students' teaching materials or leisure Because it can be used for the purpose, it is environmentally friendly to reduce the cause of polluting the environment and to maintain the clean nature by illegally dumping the used battery.
