Description
FIG. 1 is a perspective front View of a filament bulb;
FIG. 2 is a front View thereof;
FIG. 3 is a left side View thereof;
FIG. 4 is a rear View thereof;
FIG. 5 is a right side View thereof;
FIG. 6 is a top plan View thereof; and,
FIG. 7 is a bottom plan View thereof.
In the drawings, the broken lines depict environmental subject
matter only and form no part of the claimed design.
Disclaimer: The glass plunger surrounding the filament, the lamp
holder beneath the filament as well as the screw base are shown in
broken lines because they are not part of the claimed design, but
are considered necessary to show the environment in which the
design is associated.
Secondly, in the center of the filament bulb several groups of
vertically oriented LED wires are shown wherein each group contains
of three LED wires. Only one group of three LED wires is shown in
solid lines. The purpose of showing only one group of three LED
wires in solid lines is that the second and any further group of
three LED wires are identical to said group of three LED wires that
is shown in solid lines. Therefore, any repetition of said group of
three LED wires--that is shown in solid lines--is shown in broken
lines.
Thirdly, the vertically oriented wire support bar in the center of
the filament bulb that connects the ends of each of the LED wires
is part of the claimed design and, therefore, shown in solid
lines.
