The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, 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 belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Referring to Fig. 1, be a concrete schematic diagram 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, described fluorescent tube part 1 comprises glass tube 10 and is arranged in two of described glass tube 10 two ends first with electrode (figure be expressed as first first with electrode 101 and second first with electrode 102), and described power pack 2 provides described two firstly to use 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 described first first during with electrode 101 faults, and described power supply 3 and described first head are switched to being electrically connected between described power supply 3 and described 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 in running order head with electrode or backup electrode.
As shown in Figure 1a, be that the fluorescent lamp that comprises a plurality of backup electrodes is formed schematic diagram.Wherein, a plurality of backup electrodes are separately positioned near its corresponding first using 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 is first with electrode 102, second backup electrode 112,2n+2 backup electrode 122 (n is a nonnegative integer, as 1,2,3 ...).When first head used electrode 102 faults with the electrode 101 or second head, 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 the first first electrode 101 of using and works (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 comprises the concrete structure schematic diagram 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, be useful on the exhaust nozzle of exhaust on the stem stem, in this example simultaneously, first head is electrically connected with power pack by contact conductor a, b with electrode, first backup electrode is electrically connected with power pack by contact conductor a, c, and when needs switched to first backup electrode with first head with electrode, it was just passable only the electrical connection of contact conductor b need to be switched to contact conductor c.
Shown in Fig. 2 a, first promptly first head is electrically connected with power pack by contact conductor a, b with electrode with electrode and backup electrode also common electrode lead-in wire not, and first backup electrode is electrically connected with power pack by contact conductor c, d.
Wherein, the number of the backup electrode that fluorescent tube part 1 comprises can be that head uses number of electrodes purpose positive integer doubly, and promptly 2 positive integer doubly.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 standby with electrodes, and waited near the first usefulness electrode of being placed in respectively of number.Wherein, these backup electrodes can also can adopt other method setting according to the method setting shown in Fig. 2 c described later when being provided with, can be equidistant as electrode spacing at the electrode of same end, also can be not equidistant or the like.
