An electronic neon lamp transformer

Abstract

An electronic neon lamp transformer include a transformer body, A case is mounted on the outer surface of the transformer main body, A pow supply interface and a switch are arranged on that side of the shell, A voltage-changing coil is installed inside the shell, A reference ballast is installed on one side of the transformer coil, A neon lamp tube is mounted on one side of the shell, A lead is arrange between that neon lamp tube and the reference ballast, A thyristor is instal inside that neon lamp tube, A discharge needle is arranged at both ends of the neon lamp tube, At that bottom end ofthe discharge needle, an overvoltage protector is instal, through the thyristor inside the neon tube, it is possible to open the circuit farther away from the output or when one of the pipes burns out, When one end of the neon tube is open circuit, the corresponding output end of the neon tube can be discharged through the discharge needle, and the discharge high voltage is introduced into the overvoltage protector to protect the circuit through the design of installing the discharge needle at both ends of the neon tube.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an electronic neon lamp transformer. Background technique [0002] The advantages of electronic neon lamp transformers are: light weight, convenient manufacture, and saving metal materials. At present, the quality of electronic transformers produced in China is stable and has a certain scale, and some enterprises export them in batches. However, the brightness of electronic transformers produced by many units is not as bright as it should be, and it is a bit dwarfed when used outdoors. Electronic transformers are divided into two types: DC and AC. Due to the one-way conduction of DC electronic transformers, one end of the lamp tube is bright and the other end is dark. And because the output frequency of the electronic transformer will be affected by the length of the load lamp, in the same neon sign, the different lengths of each lamp will also cause uneven light colors and...

AI Technical Summary

Problems solved by technology

And because the output frequency of the electronic transformer will be affected by the length of the load lamp tube, in the same neon sign, the phenomenon of uneven light color will also occur due to the different length of each lamp tube.

[0003] The existing electronic neon lamp transformer is prone to damage in two cases. One is that when the place far from the output end is open or one of the tubes burns out, the output load increases slowly, eventually burning out the power supply. Another situation is that when there is an open circuit near the output terminal, a discharge phenomenon occurs between the two output terminals and the power supply is damaged. The existing electronic neon lamp transformer only has a design of a fuse to realize the circuit breaker protection of the line, which cannot satisfy these two conditions. In this case, the use effect is not good
