Abstract:
1. A lighting block using solar cells, comprising: a case including a light transmission section, light being emitted and received through the light transmission section; a light emitting assembly mounted within the case adjacent an inner surface of the light transmission section, the light emitting assembly allowing transmission of sunlight through the light transmission section, wherein the light emmitting assembly includes a light guide plate mounted adjacent the inner surface of the light transmission section and light sources that irradiate light through a side wurface of the light guide plate; a solar cell assembly mounted within the case adjacent the light emitting assembly, the solar cell assembly receiving sunlight passing through the light transmission section and the light emitting assembly, and generating electric power; a capacitor installed within the case and storing the electric power generated by the solar cell assembly; and a controller installed within the case and controlling the supply of stored electric power to the light emitting assembly; wherein the light guide plaate includes a light reflecting assembly substantially parallel to the light transmission section and realized through protrusions formed on a surface of the light guide plate farthest from the light transmission section, the protrusions reflecting light from the light emitting assembly through the light transmission section.
