ABSTRACT:
This invention is related to a lamp bulb with optical pattern, which consists of a bulb body, a filament and a conducting wire. The filament in the bulb body was conducted out from the tail of the bulb body by the conducting wire. The head of the bulb body is a solid, the outside is a convey arc and the inside is a triangle. The filament is connected to the conducting wire in a straight line. The bulb of the present invention has a higher luminosity and can use fully the light emitted from the filament. Because of the special structure in the bulb body, the light beam emitted by the bulb forms beautiful patterns. For example, it can form directly eye-shaped or solar eclipse-like aureola halo patterns.
