[0009] As a further improved scheme of the utility model: a plurality of equal interval arrangement light transmission holes are arranged on the light shielding strip.

[0010] Beneficial effect: the light emitting electric wire of the utility model adopts the technical feature that the light emitting electric wire comprises two parallel arranged conductors, an insulating layer is arranged outside the conductor, a sheath is extruded and wrapped outside the insulating layer, at least one longitudinal electroluminescent wire is further arranged in the sheath between the two conductors, a longitudinal slot exposing the back of the electroluminescent wire is arranged on one side of the sheath along the electroluminescent wire, the light emitting electric wire further comprises a light shielding strip which can be embedded into the longitudinal slot and covers the electroluminescent wire, so that the two parallel arranged conductors in the light emitting electric wire of the utility model have the same power transmission effect as ordinary electric wires, and the electroluminescent wire between the two conductors will emit colored decorative light along the wire after being electrified, the light shielding strip is installed into the longitudinal slot in the section where colored decorative light is not needed, so as to shield the local light of the electroluminescent wire, thereby achieving the purpose of conveniently controlling the light emitting length and light emitting position and meeting the use needs of decoration engineering.

The technical feature that the electroluminescent wire is composed of an electroluminescent wire core and a colored fluorescent plastic sleeve wrapped outside the electroluminescent wire core makes the electroluminescent wire emit decorative light of different colors by using colored fluorescent plastic sleeves of different colors, so that the color is more rich and the decoration effect is better. The technical feature that the width of the back of the electroluminescent wire exposed in the longitudinal slot is less than the diameter of the colored fluorescent plastic sleeve prevents the electroluminescent wire from falling off from the sheath while ensuring that the light emitted by the electroluminescent wire can be fully irradiated. The technical feature that a transverse cutting groove or notch is arranged on the light shielding strip at every certain distance makes the light shielding strip be cut into appropriate length by tearing in the construction process, so that the construction is more convenient. The technical feature that a plurality of equal interval arrangement light transmission holes are arranged on the light shielding strip makes the light emitting electric wire of the utility model simulate the LED lamp strip to present the effect of string bead light emission, which overcomes the disadvantage that ordinary electroluminescent wires cannot emit light.
