With reference to the accompanying drawings, describe split-pole fluorescent lamp of the present utility model in detail.
Shown in Fig. 1 (a), on split-pole fluorescent-lamp tube 2 of the present utility model, be close to and be provided with the split-pole made from electric conductor 1.Split-pole 1 can be shown in the profile of Fig. 1 (b) like that, envelope a smaller part circumference of fluorescent tube with conducting strip, so that half circumference, also can be shown in Fig. 1 (c) like that, form split-pole 1 on the fluorescent tube by some narrow conductive strips or lead axially are attached at along fluorescent tube.The length of lead can equate, also can be different.Under the situation about being uneven in length of lead, its length of can successively decreasing regularly.The derivation lead-in wire that label 3 expressions are drawn from split-pole 1, label 4 expressions are positioned at the metal end at fluorescent tube 2 two ends.One end of split-pole 1 and lead-in wire 3 all is connected on the metal end.
When the fluorescent tube of fluorescent lamp is annular, split-pole 1 can be made the ring shaped conductor of being close on the fluorescent tube 2.When the fluorescent tube of fluorescent lamp is the H type fluorescent tube of the short and small compactness shown in Fig. 1 (d), can correspondingly split-pole 1 be made the U type electric conductor of being close on the fluorescent tube 2 that matches with lamp tube shapes, its shape is shown in Fig. 1 (e).Lead-in wire 3 links with an end of split-pole 1.
Split-pole 1 can form its conductive layer as aluminium foil by foil, also can be by the conducting powder that is sprayed on tube outer wall or the inwall, and for example carbon dust or metal powder form conductive layer, this conductive layer dual-purpose can be come refracted ray like this, to increase positive lumen number.
But which kind of shape no matter described split-pole 1 have, and the one end generally all will begin from an end of fluorescent tube to extend, and its other end then can arrive, and also can not arrive the other end of fluorescent tube.
