「電球」が提案されている。提案された電球を次に示
す。[0003] Three lead wires 103, 10 from the base 102 side.
Since the wires 6, 108 project in a cantilever manner, these wires 103, 106, and 108 swing greatly toward the tips (upper ends) when subjected to vibration. The shield 104 further away from the base 102 has a large amplitude, and if the shield 104 is not firmly welded to the common conductor 103, a response delay occurs in the shield 104 with respect to the common conductor 103,
The amplitude is further increased, and the stress of the passing beam filament 105 disposed along the amplitude is increased, resulting in shortening the life. Therefore, a “bulb” disclosed in Japanese Utility Model Laid-Open Publication No. 64-2356 has been proposed. The suggested bulb is shown below.
