Discharge starter for a fluorescent lamp and compact fluorescent lamp and corresponding fluorescent lamp mounts for such

摘要

A glow starter for fluorescent lamp and the corresponding lighting fixtures therefor are disclosed. The unique glow bottle of the invention comprises a stem assembly (1) having a short lead wire (2), a bimetal sheet (3) spot-welded on the short lead wire, and a long lead wire (4); an envelope (5), said stem assembly (1) being sealed within said envelope; and discharge gas (6) filled in the envelope (5) after vacuumization; the short lead wire (2) is coated with cesium-based compound (8) and a glass, ceramics or metal lantern ring(9) is disposed around the short lead wire (2). According to the invention, metal cesium with low work function is adopted, so the starting under a completely dark condition is implemented by means of field emission, and the requirements of environment protection are fully met because of replacing the radioactive material of the prior art with cesium-based compound; the release amount of cesium is controlled by using the lantern-ring structure, thus the electrical performance of the glow starter can comply with the regulations of the national or international standard.
