• This kind of light emitting device was used in a building or a Christmas tree.
• the conventional light-emitting device had the following drawbacks, so the installation location was greatly restricted. For this reason, there is a problem in that it can be used only for an extremely narrow range of applications.
• the present invention overcomes this problem and provides a light emitting device used for a wide range of applications.
• the first disadvantage of the conventional light emitting device is that it is destroyed and its life is short.
• the light-emitting element of the light-emitting device 5 was broken by a glass bulb, and was easily broken, and the life was relatively short due to a poor discharge state or cut off of the filament. As a result, maintenance work, such as replacing tubes, was difficult.
• Fig. 13 shows a side view of the light-emitting element mounting part. To mount the light-emitting bulb 6 as a light-emitting element, first attach the socket 7 to the tape-like electric wire, and then attach the light-emitting bulb to this socket 7. 6 was installed. The length with the arc tube 6 attached is It was even one centimeter long. In addition, in FIG. 13, 7-1 is a terminal of the socket 7.
• a third disadvantage is that batteries are used as power sources.
• the luminous bulb was a Neon lamp, at least a voltage of 50 to 60 V was required to emit light, so that it could not be emitted with a dry cell.
• the electric current capacity of the incandescent lamp was large, and using a dry battery quickly consumed it, making it impractical. Therefore, it was operated with a large power supply such as a commercial power supply (voltage 100 V, 220 V).
