Description
Technical field
The utility model relates to that a kind of to be used to control common fluorescent lamp bright dark to realize that static lamp box presents the dynamic lamp house controller of dynamic colorful variation, belongs to the advertising equipment field, is specially adapted to plane lamp box advertisement.
Background technology
The StoreFront signboard is the most general field of lamp box advertisement applications, static use the lamp house cloth air brushing, lights lamp box evening, uses meteor lamp or neon light dynamically, and the former brightness is not enough and change stiffly, and latter's effect on daytime is not good enough, involves great expense and damage easily.Can judge by analysis the electronic fluorescent lamp ballasting circuit, fluorescent lamp also can be realized the dynamic effect as neon light, and can select the glow color more much more than neon light by pad pasting, the lamp box effect of making thus on daytime is just as common lamp box, evening, effect was just as neon light, and low cost, only expensive slightly than common lamp box, by the design of lamp box picture and the selection of light color, establishment light and shade flicker control program, can produce colourful variation effect, be the development trend of lamp box advertisement.But the problem that this advertising lamp box exists at present is: ballast all is mounted on the daylight lamp holder, and dispersed placement, give and install and keep in repair and brought very big inconvenience, particularly be difficult to realize centralized control, form complicated change system for a lot of fluorescent tubes of needs, just be difficult to realize.
Summary of the invention
The purpose of this utility model provides a kind ofly to be convenient to installation and maintenance and can to realize central controlled dynamic lamp house controller to the advertising lamp box that many fluorescent tubes are formed.
The technical scheme that realizes above-mentioned purpose is: a kind of dynamic lamp house controller, comprise casing and circuit board, it is characterized in that: circuit board is made up of integrated module type electric ballast group drive plate and flicker control circuit board, the flicker control circuit board links to each other with each ballast with plug by many group leads, to control lighting and blanking of corresponding fluorescent lamp, integrated module type electric ballast group drive plate and flicker control circuit board all are inserted in the casing.
After adopting technique scheme, each ballast of control fluorescent tube is made modular organization formation electric ballast group and is installed concentratedly in the circuit board, and by organize leads with the flicker control circuit board more and link to each other with plug, flicker control circuit by the flicker control circuit board can be realized centralized control to the ballast group, thereby realize centralized control to many fluorescent tubes in the lamp box, because integrated module type electric ballast group drive plate and flicker control circuit board all are inserted in the casing, in case ballast takes place to be damaged, as long as integrated module type electric ballast group drive plate is extracted out in casing, the ballast that more renews both can, and again the integrated module type electric ballast group drive plate fixed is inserted casing and get final product, thereby install and keep in repair quite convenient.Be integrated with multichannel ordinary electronic ballasting circuit on the electric ballast drive plate, electronic ballast circuit adopts 2 output transformers that power output is distributed to 2 fluorescent lamps, the control signal that the flicker control board is come is connected to the switch for fluorescent lamp control circuit, control the break-make of corresponding fluorescent tube shunt capacitance, thereby controll day light modulation switch, note, when fluorescent lamp cuts out, electric ballast is still in work, filament of fluorescent lamp still has electric current to flow through, just voltage is reduced to deficiency so that the fluorescent material build-up of luminance, so again, the build-up of luminance fluorescent tube is as long as cut off shunt capacitance, get final product with a little higher than voltage of normally lighting, the fluorescent tube blackout that can avoid causing because of the frequent build-up of luminance of light is damaged, and then has prolonged the useful life of fluorescent tube.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, 2, a kind of dynamic lamp house controller, comprise casing 1 and circuit board, circuit board is made up of polylith integrated module type electric ballast group drive plate 3 and a flicker control circuit board 5, each piece feature board is powered separately, flicker control circuit board 5 links to each other with each ballast with plug by many group leads, to control lighting and blanking of corresponding fluorescent lamp, integrated module type electric ballast group drive plate 3 and flicker control circuit board 5 all are inserted in the casing, tank floor has the empty and electric power incoming line hole of fluorescent tube outlet, and installed inside has air switch at the bottom of the case.
As shown in Figure 3, the flicker control circuit on the flicker control circuit board is made up of single-chip microcomputer 6, address decoding circuitry 7, output latch circuit 9, output driving circuit 10 and 485 bus control circuits 8 of tape program memory.As shown in Figure 4, integrated module type electric ballast group drive plate 3 is made up of ordinary electronic ballasting circuit, power distributing circuit and switch for fluorescent lamp control circuit.
As shown in Figure 5, the switch for fluorescent lamp control circuit is by electric bridge B1, B2, B3, magnetic ring coil L21, L22, triode Q3, Q4, capacitor C 10, C11, C12 and resistance R 21, R22, R23 form, and when electric current flows through coil L22, induce voltage on magnetic ring coil L21.
