I have. In order to realize such a light-emitting device, it is necessary to combine not only a light-emitting body such as an LED, but also a pedestal for fixing it, a power supply such as a battery, and a plurality of accessory devices such as a blinking switch circuit. is there.

For example, in the case of causing LEDs to emit light, conventionally, it has been necessary to separately provide not only individual LEDs but also additional devices such as a power supply and a control device, and to connect all of them with wires. In addition, in the case of a battery-integrated type in which accessories such as batteries are integrated with the LED, the wiring is completed by itself, but it is necessary to replace the battery or to obtain waterproofness for outdoor use It was necessary to separately provide a waterproof seal and the like.

[0004] Conventionally, when a wall surface of an advertisement or the like is decorated by using a light emitting device, a fluorescent lamp or a neon tube is used, so that not only an auxiliary device such as a transformer or a control device is provided but also from inside the building. Power lines and control lines had to be provided through the wall. For this reason, a large amount of money was required to be commissioned to a specialist, and there were many restrictions such as the need to change the design of the wall decoration according to the shape and structure of the building. Further, in the conventional technology using a fluorescent lamp, a neon tube, and the like, daily maintenance such as replacing a broken one is indispensable.
