Regarding.

1 and 2 show a conventional light emitting device of this type.

Reference numeral 1 denotes a band-shaped electric wire, which has a structure in which band-shaped conducting wires 4 and 5 are sandwiched between an electrically insulating front-side band-shaped body 2 and a back-side band-shaped body 3.

6 is an incandescent light bulb, and its bottom side is fitted into a light bulb mounting tube 7 made of soft synthetic resin.

8 and 9 are lead wires of the light bulb 6.

To attach the light bulb 6 to the strip wire 1, a part of the front strip 2 covering the conductors 4 and 5 is removed, and the lead wires 8 and 9 are connected to the front strip 2 from that part. 4 and 5, and then the light bulb attachment tube 7 is pressed onto the front side strip 2 and then heat-sealed.

However, such conventional light emitting devices have the following various drawbacks.

(a) Since the light bulb 6 cannot be removed from the electric strip 1, if the light bulb 6 burns out, it is not possible to replace only the light bulb 6, but the entire light emitting device must be replaced.

(b) Since the light bulb mounting tube 7 is heat-sealed to the front strip 2, the front strip 2 surrounding the bulb mounting tube 7 will also melt, creating ugly unevenness on its surface, and each strip 2, 3 is curved, resulting in a significant loss of aesthetic appearance.

(c) When the front side band-shaped body 2 is made transparent, the lead wires 8 and 9 can be seen as they are from the front side of the band-shaped electric wire 1, and this also significantly impairs the aesthetic appearance.

b) In order to insert the lead wires 8, 9 between the front side strip 2 and the conductor 4.5, the conductor 4,
Since we have to remove part of the part that covers 5,
Incomplete insulation may occur on the surface side of the band-shaped electric wire 1, and there is a possibility that an electric shock accident, an electric leakage accident, or a discharge accident will occur.

(E) The lead wires 8 and 9 are simply connected to the front side strip 2 and the conductor 4.
, 5, the lead wires 8.9 are only pressed against the conductive wires 4.5, so that the lead wires 8.9 may have poor contact with the conductive wires 4, 5.
