Abstract
The utility model relates to a photo frame luminescent lamp, in particular to a special-shaped lamp based on singlechip control, and belongs to the field of photo frame decoration. A plurality of luminescent lamps (1) are connected to a QFP (Quad Flat Package) STC89C52 singlechip by a driving circuit; the STC89C52 singlechip is connected with a power supply; the luminescent lamps form the special-shaped lamp (2); and the special-shaped lamp (2), the STC89C52 singlechip and the power supply are arranged in a photo frame (3). The special-shaped lamp has an attractive housing, is simple in structure, low in cost, convenient to place and carry, high in practicability, and high in reliability, and can realize intelligent control.
Description
Technical field
The utility model relates to a kind of photo frame electroluminescent lamp, and is particularly a kind of based on monolithic processor controlled special-shaped lamp, belongs to photo frame and decorates the field.
Background technology
Electroluminescent lamp miscellaneous has brought color to the city on the market at present, but existing electroluminescent lamp is all to adopt that the serial or parallel connection of electroluminescent lamp glimmers etc., more convenient when being used for the large article decoration, but problem miscellaneous can appear when decorating for little article such as photo frames, light-emitting mode is single, uses very inconvenient.
The utility model content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is: provide a kind of and can overcome defects, and intelligent, practical, reliability is high, simple in structure based on monolithic processor controlled special-shaped lamp.
The technical scheme that its technical problem that solves the utility model adopts is:
Describedly comprise electroluminescent lamp based on monolithic processor controlled special-shaped lamp, it is characterized in that: described electroluminescent lamp accesses the STC89C52 single-chip microcomputer of QFP encapsulation by drive circuit, the STC89C52 single-chip microcomputer connects power supply.
Described have 4 I/O mouths based on monolithic processor controlled special-shaped lamp employing STC89C52 single-chip microcomputer, and each I/O has 8; The single-chip processor i/o mouth can be expanded, and cost is low; The driving of LED, after the light-emitting diode conducting, tube voltage drop is in the 1.7-2V left and right, luminous power is relevant with the drive current size, for safety with satisfy power consumption demand, general Current Control shows if Light-Emitting Diode is dynamic scan at 3-10mA, for guaranteeing good brightness effects, drive current can be larger.LED is connected with single-chip microcomputer, and after the single-chip microcomputer electrification reset, I/O exports high level, after preventing electrification reset, and whole LED controlled lighting not, so, the negative electrode of LED is connected with the single-chip microcomputer pin, when single-chip microcomputer pin output low level, LED is lit.Can drive the load of 20mA due to STC single-chip processor i/o mouth, so all LED directly drive by single-chip microcomputer.
Described electroluminescent lamp is several, and several electroluminescent lamps form special-shaped lamp, and described special-shaped lamp, STC89C52 single-chip microcomputer, power supply are arranged in photo frame.The abnormity lamp can be realized the picture heart, horse race lamp, flicker, arrow wear " heart ", colored ribbon is around texts, be set in photo frame and decorate.
Described electroluminescent lamp is the LED lamp of multiple luminous integrated mode.Cost is low, realization is easy.
Described power acquisition power supply adaptor, stabilized voltage power supply, Switching Power Supply or battery.Optimization power supply adapter wherein, cost is low, attractive in appearance being easy to carry.
The beneficial effect that the utility model has is: the described LED lamp that adopts varied of single-chip microcomputer design to show based on monolithic processor controlled special-shaped lamp, this lamp is arranged in heart by many LED, consist of an arrow and colored ribbon with seven color LED in the middle of " heart " shape pattern, utilize Single-chip Controlling LED to light order, can realize picture " heart ", horse race lamp, flicker, arrow wear " heart ", colored ribbon is around texts.The utility model is simple in structure, cost is low, attractive in appearance being convenient to of shell put, carried, and can realize that intellectuality is controlled, practical, reliability is high.
Description of drawings
Fig. 1 is the utility model structural principle block diagram;
Fig. 2 is the utility model structural representation;
In figure: 1, electroluminescent lamp 2, special-shaped lamp 3, photo frame.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Fig. 1-2, based on monolithic processor controlled special-shaped lamp, comprise electroluminescent lamp 1, described electroluminescent lamp 1 accesses the STC89C52 single-chip microcomputer of QFP encapsulation by drive circuit, and the STC89C52 single-chip microcomputer connects power supply.
Described electroluminescent lamp 1 is several, and several electroluminescent lamps form special-shaped lamp 2, and described special-shaped lamp 2, STC89C52 single-chip microcomputer, power supply are arranged in photo frame 3.
Described electroluminescent lamp 1 is the LED lamp of multiple luminous integrated mode.Power acquisition power supply adaptor, stabilized voltage power supply, Switching Power Supply or battery.
Operation principle and use procedure:
The LED lamp bank is listed as intentionally is fixed in photo frame after the shape such as type, arrow punching, connect power supply, single-chip microcomputer work, single-chip microcomputer is controlled the LED lamp by drive circuit, LED lights successively, and namely first LED lights, and continues for some time, then second LED lights, simultaneously, first LED extinguishes, and every LED lights certain hour, combine like this, just produce the flowing water effect.Can adopt a cyclic program to realize, every duration that lamp is lighted, can adopt software delay to obtain.
Other glittering patterns all realize by the STC89C52 mcu programming.
