Embodiment Construction

[0012] Such as figure 1 The neon light transformer shown includes a neon light tube 1 , electrodes 2 , a transformer and a neon light power supply 3 , a power supply 3 is connected between the two electrodes 2 , and a transformer is connected between the power supply 3 and the neon light electrode 2 . The transformer is an autotransformer 4, the output end of the power supply 3 is connected to some turns of the individual winding of the autotransformer, and the electrode 2 is connected to the boost output end of the winding.

[0013] The autotransformer 4 includes a plurality of boost output terminals, each of which is connected to an output node 5 .

[0014] A rotary switch 6 is arranged between the electrode 2 and the boost output terminal of the transformer, and the rotary switch can select the output node 5 of the boost output terminal to be connected. The boost output node connected to both ends of the electrode is rotated by the rotary switch 6, so that the voltage a...

Abstract

The invention relates to neon lamps, in particular to a neon lamp transformer. The neon lamp transformer comprises a neon lamp tube, electrodes, a transformer body and a neon lamp power source. The power source is connected between the two electrodes, and the transformer body is connected between the power source and the neon lamp electrodes. The transformer is a self-coupled type transformer, the output end of the power source is connected to part of wire turns of an independent winding of the self-coupled type transformer, and the electrodes are connected to the boosting output end of the winding. After above structure is used, the self-coupled type transformer is simple in structure, and a voltage output end can be arranged freely. Meanwhile, a plurality of boosting output points are arranged on the winding of the self-coupled type transformer, thus a plurality of input voltages can be selected on the neon lamp electrodes, and the purpose of adjusting the luminance of a neon lamp can be achieved.

Description

technical field [0001] The invention relates to a neon lamp, in particular to a neon lamp transformer. Background technique [0002] The neon transformer is an important part of the neon lamp, which provides high voltage to both ends of the neon lamp tube. Commonly used iron-core transformers have complex structures, and the output of iron-core transformers is single. The luminance of common neon lights is monotonous, which is not conducive to improving the advertising effect, especially when used indoors. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-output neon lamp transformer. [0004] In order to solve the above-mentioned technical problems, the neon lamp transformer of the present invention includes a neon lamp tube, electrodes, a transformer and a neon lamp power supply, a power supply is connected between the two electrodes, a transformer is connected between the power supply and the neon ...
