Abstract

The utility model relates to a light decoration controller with an electronic storage, which in advance stores the changing condition of lights to be used into an electrically programmable read-only memory EPROM. The address of the electrically programmable read-only memory EPROM is given by a counter, with the effect of an impulse action generated by a pulse generator. The data stored in the address is output to a data line to control the switching on and off of a bidirectional controlled silicon. Thus, lights connected with the bidirectional controlled silicon generate brightness variation and various light effects. The light decoration controller with an electronic storage can generate hundreds of light decoration variations. The light decoration controller with an electronic storage which is suitable for the light control of advertisement propaganda, decoration of buildings, dance halls and stages can generate various light effects.

Description

Light decoration controller with programmed memory

The utility model is an electronics memory-type lamp decoration controller.

Existing various forms of lamp decoration controllers, its purposes literal that to be control is made up of light or the light and shade of pattern make it eye-catching, thereby reach enhancement people memory, advertisement or produce special visual effect before the lights.The structure of existing lamp dimmer is that the light variation that can produce is only several once making with Mechanical Contact formula or the hardware circuit that constitutes with electronic component basically.Adopt computer-controlled lamp decoration controller, though can produce multiple variation, its cost height, non-general user can take into account.

The purpose of this utility model provides a kind of cheap, but can produce the electronics memory-type lamp decoration controller that hundreds of light changes.

Of the present utility model being characterised in that, with the various lamp decoration situations of change that must use be stored in advance among the electrically programable ROM EPROM, under the impulse action that pulse generator produces, provide the address of electrically programable ROM EPROM through counter, the data of being deposited in this address are passed on the data wire, the break-make of control bidirectional triode thyristor, thus the lamp decoration light and shade of contacting mutually with bidirectional triode thyristor is changed, produce various lighting effects.

The utility model can be used for advertising, and decorating building, dance hall and stage are made the control lamp decoration, produces different lighting effects and uses.

Solution of the present utility model can further be illustrated with following accompanying drawing.

Fig. 1 is the circuit diagram of storage of the present utility model and driving part, and Fig. 2 is that pulse of the present utility model produces circuit diagram partly.

In Fig. 2, to form oscillator by the NE555 time-base circuit and produce pulse at the P point, this pulse is passed to the Bin input of the binary counter 74LS93 in the right, Fig. 1 bottom, thereby B at this binary counter, C produces binary code on the D output, the A of this code and EPROM2732 ₃-A ₈Level on the pin provides the address of EPROM2732 jointly, and making the data content that is stored in advance on this address among the EPROM2732 is that level state comes across delivery outlet D ₀-D ₇On, D ₀-D ₇Level after anti-phase again the conducting of the bidirectional triode thyristor that joins with it of control with end, work as D ₀-D ₇Last a certain position is as D ₃Level when being low level, then with D ₃Thereby the rp-drive that joins is output as high level and makes the bidirectional triode thyristor conducting that is connected with this rp-drive output, and the lamp decoration that this makes and this bidirectional triode thyristor is in series is luminous; As D ₃Level when being high level, then with D ₃The rp-drive that is connected ends the bidirectional triode thyristor that is connected with this rp-drive, thereby the lamp decoration that is in series with this bidirectional triode thyristor is extinguished.D ₀-D ₇The high and low level of output makes the bidirectional triode thyristor that is connected with them produce conducting and end behind rp-drive, these silicon controlled conductings with by making lamp decoration with each controllable silicon polyphone produce luminous or extinguishing, change thereby produce different light.The also available driven in phase device of rp-drive replaces, and just with the inner content changing of depositing of EPROM, high level changes low level into, low level changes high level into and gets final product.

The A of EPROM2732 among Fig. 1 ₃-A ₇The address divide in addition by the A output of the 74LS93 in the right and the A of the 74LS93 in the left side among Fig. 1, B, C, the level decision of D output, they have determined 32 groups of memory addresss, i.e. A ₃-A ₇By 00000 to 11111, every group of memory address has 8 memory cell, (is the A of EPROM2732 ₀-A ₂8 kinds of variations are arranged, by 000 to 111), work as switch S ₇When being in " circulation " position, the A of EPROM2732 ₈Be high level, provide 32 groups of memory blocks, work as switch S ₇The A of EPROM2732 is in low level when being in " demonstration " position, provides 32 groups of other memory block LEDs ₁-LED ₃₂Indication provides uses that group memory block.The output of the 74LS93 binary counter in the right among Fig. 1 also drives 16 simultaneously and selects a decoder 74LS154(only to use its 8 outputs, does eight and selects a decoder to use).Make on its 8 output lines an output low level is sequentially arranged, all the other are high level, behind rp-drive, sequentially make one of them the bidirectional triode thyristor conducting that is connected with rp-drive, make with the lamp decoration of this bidirectional triode thyristor polyphone luminous, order is gone down, make these 8 groups of lamp decorations luminous in turn, produce circulation and chase effect.

Use for convenient, added each control switch S ₂, S ₄, S ₆, S ₇Switch S ₆Setting be in order to satisfy the needs of 8 groups of circulation lamps of control and 4 groups of circulation lamps of control.Switch S ₂And S ₄Be to be made for locating and displaying a kind of or four kinds of variations or 32 kinds of variation circulation demonstration uses, work as S ₄And S ₂When being in " carry 1 " and " carry 2 " respectively, the lamp decoration controller provides 32 kinds of lamp decoration variations in proper order; Work as S ₂Be in " stopping 1 " S ₄The lamp decoration controller will be according to switch S when being in " stopping 2 " ₁And S ₃The pulse that provides determines only to show that a kind of variation.Switch S ₇Control A ₈High-low level, thereby select to adopt in " circulation " or " demonstration " type that a kind of, each type all can have 32 kinds of variations.The program of setting in " circulation " zone does not adopt 8 groups of light complete basically
