Abstract

Mini-type decorative bulb capable of emitting light through entire circumferential face, including a main body made of blank glass tube. A bead is disposed in the main body for locating two conductive wires. The conductive wires partially extend out of the main body for connecting with a power source. Inner sections of the conductive wires extend into the main body for connecting with tungsten filaments. When a wick composed of the bead, the conductive wires and the tungsten filaments is magnetically attracted and located in the main body, top end of the glass main body is blown and rounded to form a dome face through which light can pass. The other end of the main body is clamped and closed to form a flat end which can be easily plugged into a bulb seat.

Claims

1. Mini-type decorative bulb capable of emitting light through entire circumferential face, comprising a main body made of blank glass tube, a bead being disposed in the main body for locating two conductive wires, the conductive wires partially extending out of the main body for connecting with a power source, internal sections of the conductive wires extending into the main body for connecting with at least one tungsten filament, when a wick composed of the bead, the conductive wires and the tungsten filament is magnetically attracted and located in the main body, a previously clamped and sealed top end of the glass main body being blown and rounded to form a dome face through which light can pass, the other end of the main body being clamped and closed.

2. Mini-type decorative bulb capable of emitting light through entire circumferential face as claimed in claim 1, wherein the other end of the main body opposite to the dome face is clamped and closed to form a flat end which can be easily assembled with a bulb seat.

3. Mini-type decorative bulb capable of emitting light through entire circumferential face as claimed in claim 1, wherein two tungsten filaments are connected with inner sections of the conductive wires and positioned in different color sections, the conductive wires above the upper tungsten filament and the conductive wires between the tungsten filaments being formed with arched sections.
