Low voltage electronic scanning neon lamp

The utility model relates to a kind of Low-voltage Electronic scanning neon light, especially electronic instrument and electric vacuum technology field.

At present, our employed high-pressure glass vacuum neon light, its fluorescent tube domestic demand is filled a certain amount of pernicious gas mercury (mercury vapor), use this high pressure neon light and will light, just must be equipped with the high pressure of 10000-20000V, use very dangerous, and fitting operation is also very inconvenient, can't move when especially working at all, can not adjust control and obtain multi-functional demonstration it as required, key be the function that it does not have scanning, the control appliance volume is big, the cost height, the single tube power consumption is very big, and maintaining is also all very difficult.

The purpose of this utility model is to provide a kind of novel Low-voltage Electronic scanning neon light again at the problem that above-mentioned high pressure neon light is occurred, it is simple in structure, control voltage is low, it is dangerous to solve existing high pressure neon light, the cost height, problems such as poor reliability can not scan, single power consumption is big, and the narrow and function of the scope of application is few.

The purpose of this utility model realizes with following method, on control circuit, use for complete machine with low-tension supply, change into by the electric component high voltage control and to use the electronic component low voltage control, make the electrode of neon light tube change an electrode outlet line into by two electrode outlet lines, use the intermediate frequency excitation technique and realize the flicker of novel Low-voltage Electronic scanning neon light, lighting functions such as scanning and Chang Liang.

Below in conjunction with accompanying drawing the utility model is further described.
