Abstract: The incandescent lamp includes a glass bulb having a longitudinal axis and two filaments formed of a coil within the bulb supported with their longitudinal axes oriented parallel to the bulb's longitudinal axis. For supporting the filaments, three support wires are provided, each with an outer portion fixed to the bulb and extending parallel to the bulb longitudinal axis and an inner portion extending substantially perpendicular to the outer portion. The inner and outer portions of all three support wires are located in a single reference plane extending parallel to the bulb longitudinal axis. The filaments are joined to the support wires by four welded joints that can be applied in the single reference plane. The inner portions of the second and third support wires extend toward each other and are substantially aligned. The bulb has a glass seal portion through which the outer portion of the support wires extend and by which the outer support wire are fixed in a laterally spaced apart relation.
