Light emitting block

摘要: A light emitting block of this invention includes, mounted in a main body (1), solar batteries for (2) generating electric power, an double layer capacitor (3) storing the planar member (4), and emission control circuit controlling lighting portion (4). In daytime, receive ambient sunlight through surface (1A). The power accumulates (3). At nighttime, (4A) (4) automatically emits with stored (3), to make shine. in-system function provided by simplifies construction maintenance, maintains even time blackout, which provides improved response emergency situations. is mellow eye, improvement design.
