Yet, the jockey of above-mentioned electrion fluorescent tube and its transformer has its shortcoming as follows, promptly, same district two discharge lamps are to accept the antipodal generating positive and negative voltage of the same Circuit Fault on Secondary Transformer two outputs identical but polarity of size, for example, the one fluorescent tube LP11 in the first high-pressure discharge lamp area under control carves a positive voltage of accepting the first transformer T1, the first output T11 at a time, and another adjacent electrion fluorescent tube LP12 of this district accepts the antipodal negative voltage of this transformer T1 second another phase place of output T12 at the same time, because the electrion fluorescent tube of same district is very close on arrangement space, its potential difference to each other (is 500V with every electrion fluorescent tube for example greatly again, maximum instantaneous has the potential difference of 1000V between the generating positive and negative voltage of its adjacent electrion fluorescent tube), institute causes negative effect interfering with each other so that can produce noise.Electrion fluorescent tube in second district also has identical shortcoming.
The utility model content
The utility model promptly is because the shortcoming on the jockey of above-mentioned existing two high-pressure discharge lamp areas under control and its transformer, and design provides a kind of cross connection device, make the electrion fluorescent tube of each same district all respectively can keep the voltage of homophase, do not have the problem of squeezing mutually.
Characteristics of the present utility model are, the cross connection device of this pair high-pressure discharge lamp area under control and a plurality of transformers, wherein, each high-pressure discharge lamp area under control respectively includes many electrion fluorescent tubes, the secondary side of each transformer respectively has two outputs, first output of each transformer is connected to each electrion fluorescent tube in the first high-pressure discharge lamp area under control respectively, second output of each transformer then is connected to each electrion fluorescent tube in the second high-pressure discharge lamp area under control respectively, according to this, make the electrion fluorescent tube of each same district all respectively can keep the voltage of homophase, its potential difference is little, there is not the problem of squeezing mutually, very safe in the use, and avoid negative effect because of voltage-phase difference and noise jamming that the voltage drop produced thereof etc.

Embodiment
Structure of the present utility model, characteristics and effect thereof, the embodiment of adjoint Fig. 2 is described in more detail as follows.
Figure 2 shows that the connection diagram of the cross connection device of the two high-pressure discharge lamp areas under control of the utility model and a plurality of transformers.Show that of the present utility model pair of high-pressure discharge lamp area under control includes the first high-pressure discharge lamp area under control LP1 and the second high-pressure discharge lamp area under control LP2, wherein, the first high-pressure discharge lamp area under control LP1 includes many electrion fluorescent tubes for example LP11 and LP12, and many electrion fluorescent tubes that the second high-pressure discharge lamp area under control LP2 also includes identical number are LP21 and LP22 for example.The utility model also includes transformer T1 and the T2 with each district's electrion fluorescent tube number equal number, and the primary side of these transformers T1, T2 respectively is connected to one drive circuit 1,2, and these drive circuits connect with holding wire 3, and are synchronization action.The secondary side of these transformers T1, T2 respectively has two outputs, first output of each transformer is connected to each electrion fluorescent tube in the first high-pressure discharge lamp area under control respectively, and second output of each transformer then is connected to each electrion fluorescent tube in the second high-pressure discharge lamp area under control respectively.That is the first output T11 of the first transformer T1 and the first output T21 of the second transformer T2 are connected to two fluorescent tube LP11 and the LP12 of the first high-pressure discharge lamp area under control LP1 respectively; The second output L2 of the first transformer T1 and the second output T22 of the second transformer T2 then are connected to two fluorescent tube LP21 and the LP22 of the second high-pressure discharge lamp area under control LP2 respectively.
According to above-mentioned cross connection device of the present utility model, make the electrion fluorescent tube of each same district all respectively can keep the voltage of homophase, for example, the two fluorescent tube LP11 of the first high-pressure discharge lamp area under control LP1 and LP12 can obtain the positive voltage or the negative voltage of homophase simultaneously, and the two fluorescent tube LP21 of the other second high-pressure discharge lamp area under control LP2 meanwhile and LP22 also can obtain the negative voltage or the positive voltage of homophase simultaneously, between each electrion fluorescent tube of its each same district, potential difference is minimum, there is not the problem of squeezing mutually, very safe in the use, and can avoid in the prior art negative effect because of voltage-phase difference and noise jamming that the voltage drop produced thereof etc.
