Abstract
The utility model provides a digitized control switch power device for neon light. Currently, the neon light power device includes an inductance transformer and an electronic transformer, and has defects of large electricity consumption and incapable of supplying power to the fairly long and more light tubes. The utility model consists of a rectifying circuit, a filtering circuit, a digital switch circuit, a microcomputer control system, an intermediate frequency transformer distributor, a high-speed control switch and a decoder. The main operating principle is adopting a power supply with low voltage and intermediate frequency to make the neon light emit light with the same brightness as the traditional power supply. Regarding to the circuit control method, the power is organically combined with shutdown, which can not only realize the function of the common shutdown plate, but also can control the audio signal, thereby diversifying the scan. One group of power supply can take a neon light tube over 100 meters long, thereby greatly reducing the power total; besides, the utility model can work in server environments such as raining weather.
Description
Technical field
The utility model relates to a kind of control switching device that is used for neon light.In particular for the Digital Control switching power unit on the neon light.
Background technology
At present, the neon lamp power source device has two kinds of inductive transformer and electronic transformers.Its operation principle adopts and becomes 220V civil power transformation the 15000V operating voltage to supply with neon light tube, by the electrode discharge of neon light tube, and inert gas such as the helium in the activation pipe, neon and luminous.The shortcoming of this supply unit is that power consumption is big, and as inductive transformer band 10 rice lamp pipes, power is 350W, and each power supply can only be with 12 rice lamp pipes at most, and a billboard of going up km will have into hundred power supply power supplies.And, the operation under high pressure of existing neon lamp power source device, the device rapid wear, lamp tube service life is low, and the rainy day can not work.Because sequential mode is single, with low uncertainty during scanning jumping machine control circuit, with transformer, on line complexity between the fluorescent tube, the equipment cost is higher, and traditional spectacular sign requires power supply to be connected distance with fluorescent tube and is no more than 10 meters, and generally maintenance difficulty is big under the high-altitude.
Summary of the invention
In order to overcome the shortcoming of above said traditional spectacular sign power supply and scanning machine, it is a kind of fully by micro-processor controlled digitlization neon light Switching Power Supply control system that the utility model provides.
Groundwork principle of the present utility model is the power supply that has adopted the low pressure intermediate frequency, makes neon light tube emit light with the conventional power source same brightness equally.On the control mode of circuit power supply and jumping machine are organically combined, not only can realize the function of conventional jumping machine plate, and can control with audio signal, scanning is variation more.Under system controlled by computer,, under the three primary colors condition, can be combined into the countless versions color by regulating lighting tube brightness.The utility model is jumped dynamo-electric resource integrated as basic module with 8.Its main composition is: earlier the 220V civil power is modulated into the 250V DC power supply through current rectifying and wave filtering circuit, under microsystem control, produce 12V-180V intermediate frequency low-tension supply by digital switch circuit, the signal of this power supply is exported to the distributor of intermediate frequency transformer, distributor has 8 road output ports, and state fed back to microsystem in real time, signal is under the control of microsystem, export to 8 speed-sensitive switch controllers with giving the sequence switch signal that is first written in the EPROM chip, pass through decoder identification switch signal again, export to neon light tube.Neon light tube is under control of microcomputer, and according to the operation of sequential realization light on and off, The whole control system has realized that organically power supply is machine integrated with jumping.
The utility model has the advantages that:
1, energy-conservation.Because what adopt is the working power signal of low pressure intermediate frequency, voltage is adjustable between 12V-180V, and signal is an impulse wave, Gu relatively the traditional electrical sense transformer is energy-conservation more than 70% for this.
2, one group of power supply can be with the neon light tube more than 100 meters, and the power supply sum significantly reduces.
3, can in rugged environment, work, as can be in the rainy day operate as normal.
4, control mode variation.
5, the operating state detection is easy to maintenance, all adopts digital the demonstration.
6, scan mode is flexible, conventional jumping machine, audio frequency control, twilight sunset control, luminance transformation control etc.
7, owing to be the low-tension supply power supply, make the neon light tube life-span prolong.
