The specific embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Referring to Fig. 1, be a concrete sketch map of forming of fluorescent lamp in the embodiment of the invention.As shown in the figure; This fluorescent lamp comprises fluorescent tube part 1 and power pack 2; Said fluorescent tube part 1 comprise glass tube 10 with two that are arranged in said glass tube 10 two ends first with electrode (figure be expressed as first first with electrode 101 and second head with electrode 102), said power pack 2 provides said two head with being electrically connected between electrode and the power supply 3.
Wherein, fluorescent tube part 1 also comprises at least one backup electrode, as comprises that first backup electrode, 111, the first backup electrodes 111 are positioned at glass tube 10 and first with electrode 101 near first; Power pack 2 also comprises intelligence control circuit 20; Intelligence control circuit 20 is used for when detecting said first first during with electrode 101 faults, and said power supply 3 and said first head are switched to being electrically connected between said power supply 3 and said first backup electrode 111 with being electrically connected between the electrode 101.Wherein, the electrode that can claim to be in power supply status of electrically connecting is a working electrode, and promptly working electrode is that in running order head is with electrode or backup electrode.
Shown in Fig. 1 a, be that the fluorescent lamp that comprises a plurality of backup electrodes is formed sketch map.Wherein, a plurality of backup electrodes are separately positioned on its corresponding head with near the electrode.Comprise respectively that at two electrode tips first is first with electrode 101, first backup electrode 111; (n is a nonnegative integer to 2n+1 backup electrode 121; As 1,2,3......); Second first with electrode 102, second backup electrode, 112, the 2n+2 backup electrodes 122 (n is a nonnegative integer, as 1,2,3 ...).When first first with electrode 101 or second head during with electrode 102 faults, power pack 2 can switch to working electrode with first backup electrode 111 and second backup electrode 112; When first backup electrode 111 or second backup electrode, 112 faults, power pack 2 can switch to working electrode (n=1) with 2n+1 backup electrode 121 and 2n+2 backup electrode 122; And the like, when comprise in the fluorescent lamp a plurality of backup electrodes to the time, can switch successively.
Electrical connection when solid line is represented head with the electrode operate as normal among Fig. 1; When dotted line is represented first head with electrode 101 faults; First backup electrode 111 replaces first head with electrode 101 work (at this moment; First head is in off position with electrode 101, and second head still keeps being electrical connectors be in duty with electrode).
The component relationship of only illustrating shown in Figure 1, as shown in Figure 2, partly comprise the concrete structure sketch map of an end of first backup electrode for fluorescent tube among Fig. 1.Concrete; The fluorescent tube part also comprises the stem stem of fixed electrode, is useful on the exhaust nozzle of exhaust on the stem stem, in this example simultaneously; First head is electrically connected with power pack through contact conductor a, b with electrode; First backup electrode is electrically connected with power pack through contact conductor a, c, and when needs switched to first backup electrode with first head with electrode, it was just passable only need the electrical connection of contact conductor b to be switched to contact conductor c.
Shown in Fig. 2 a, first with electrode and backup electrode also not common electrode go between, promptly first head is electrically connected with power pack through contact conductor a, b with electrode, first backup electrode is electrically connected with power pack through contact conductor c, d.
Wherein, the number of the backup electrode that fluorescent tube part 1 comprises can be first with number of electrodes purpose positive integer doubly, i.e. 2 positive integer times.Fluorescent tube part 1 comprises 4 of backup electrodes altogether; Wherein two (as comprise first backup electrode 111 as the first first backup electrode with electrode 101; The 3rd backup electrode), two as the second first backup electrode (as comprising second backup electrode, the 4th backup electrode) with electrode 102.By that analogy, when fluorescent tube part 1 comprised more a plurality of backup electrode, these backup electrodes were respectively as two first subsequent use with electrode, and etc. number be placed in head respectively with near the electrode.Wherein, these backup electrodes when being provided with can according to after the method setting shown in Fig. 2 c stated, also can adopt other method setting, can be equidistant like electrode spacing at the electrode of same end, can be not equidistant or the like yet.
Shown in Fig. 2 b, be the front view and the side view of the part of the fluorescent tube in the specific embodiment of the present invention, the glass tube in this example is spiral glass pipe (also can be U-shaped pipe, straight tube etc.).Shown in Fig. 2 c, be the B-B profile of the part of the fluorescent tube among Fig. 2 b.In the present embodiment, first first all has backup electrode with the electrode and second head respectively with electrode, and with the shared lead-in wire of backup electrode separately (be respectively common electrode lead-in wire 1 and common electrode and go between 2).And, from Fig. 2 c, can find out, first first with electrode and second first with the distance of moving towards along glass tube between the electrode greater than the distance of moving towards along glass tube between first backup electrode and second backup electrode.
