    摘要: A fluorescent lamp (10) has an elongated glass envelope (12) with a mount structure (14) sealing each end (16) of the envelope (12). The mount structure (14) comprises a glass base (18) with two spaced apart lead-in wires (20, 22) sealed into the glass base (18) and extending into the envelope (12). An electrode (24) is connected between the lead-in wires (20, 22) within the envelope (12) and an electrode shield (26) surrounds the electrode (24). The electrode shield (26) has an open top (26a) and an open bottom (26b) and a wall (26c) that is substantially equidistantly spaced from the electrode (24). A support member (28) is attached only to the shield wall (26c) and to one of the lead-ins, for example, (22), thereby making the shield (26) electrically active when the lamp is operating.
