Detailed description of the invention
Fig. 1 is the layered structure schematic diagram of the utility model embodiment LED card.
Fig. 2 is the driving circuit figure of the utility model embodiment LED card.
The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments.
Specific embodiment
Referring to Fig. 1, LED card provided by the utility model includes card body, and card body is disposed with protection from top to bottom
Film 1, upper printing layer 2, middle layer 3, lower printing layer 4 and lower protective film 5 include circuit substrate 6, upper intermediate PVC in middle layer 3
Layer 31 and lower intermediate layer of PVC 32, circuit substrate 6 is embedded between intermediate layer of PVC 31 and lower intermediate layer of PVC 32, in circuit base
LED light 61 is provided on plate 6.Upper printing layer 2 and lower printing layer 4 are PVC polyvinyl chloride layer.Specifically, one can be selected first
Certain thickness PVC polyvinyl chloride layer is opened as middle layer 3, and the middle part of middle layer 3 is carried out according to the shape size of circuit substrate 6
Hollow out forms a hollow-out parts, circuit substrate 6 is then placed into hollow-out parts, finally by upper printing layer 2, lower printing layer 4, centre
Layer 3 and upper protective film 1, lower protective film 5 paste compacting to form the LED card.
Referring to fig. 2, programmable chip 62, VCC power supply 63 and multiple LED light 61 are provided on circuit substrate 6, each
Resistance 64 is provided between a LED light 61 and VCC power supply 63, LED light 61, resistance 64 are connected in series in circuit.Programmable core
One output pin of piece 62 is electrically connected with one end of LED light 61, and the other end of LED light 61 is electrically connected with resistance 64.
In the present embodiment, the voltage of VCC power supply 63 is 3.3 volts or 5 volts, and the output pin of programmable chip 62 can be with
High level signal is exported, also exportable low level signal.When the output of the output pin of programmable chip 62 is low level,
The output pin and VCC both ends of power of programmable chip 62 just produce a voltage difference, such as 3.3 volts of voltage difference, the voltage
Difference is that LED light 61 is powered, and LED light 61 is made to shine.When the output pin of programmable chip 62 exports high level, it can compile
The voltage difference very little that the output pin and VCC both ends of power of journey chip 62 are formed, LED light 61 do not shine.
LED light 61 is light emitting diode, and the quantity of LED light 61 is 30 to 40, the output pin of programmable chip 62
The quantity of quantity LED light 61 is equal.Output pin is arranged correspondingly with LED light 61, the voltage levels of output pin output
It can be controlled by the program inside programmable chip 62, the adjustable output of the height by controlling output pin output voltage is drawn
The size of voltage difference between foot and VCC power supply 63, to adjust the brightness of LED light 61.Each output pin is one corresponding
LED light 61, and each output pin is mutually independent, the voltage value of output can pass through the program in programmable chip 62
It is adjusted, the voltage value of output pin output is different, and the voltage difference at corresponding 61 both ends of LED light is just different, LED light 61
Brightness it is just different.When the voltage value of output pin output is equal with the voltage value of VCC power supply, LED light 61 both ends at this time
Voltage difference is zero, and LED light does not shine at this time；When the voltage value of output pin output is zero either low level, LED light at this time
The voltage difference at 61 both ends is 63 voltage of VCC power supply, and the brightness of LED light at this time reaches maximum.By being compiled in programmable chip 62
Enter different programs to control the voltage value of each output pin, to control the brightness of each LED light 61.Pass through control
The brightness of each LED light 61 reaches the card display effect that user wants.
It in the present embodiment, can be by can if being desirable for LED card shows the effect that cup water level slowly rises
It is incorporated into program in programming chip 62, makes way for the corresponding output pin of the LED light 61 output low level signal of cup bottom part,
The corresponding output pin of LED light 61 of upper part exports high level signal, and the LED light of bottom part is allowed first to shine；Then again
The high level signal for allowing the corresponding output pin of LED light 61 of upper part to export is changed into low level signal, such upper end
The LED light 61 divided lights, and so circulation executes above-mentioned steps, to reach the display effect that cup water level slowly rises.If needing
LED card is allowed to show the number of number or variation, it is only necessary to it is incorporated into program in programmable chip 62, it is aobvious required for allowing
The corresponding LED light 61 of number shown shines, and specific practice is that corresponding output pin is allowed to export low level signal, remaining is defeated
Pin exports high level signal out.
In the present embodiment, the power supply mode of VCC power supply 63 can power for induction coil, or battery module supplies
Electricity.Specifically, when LED card is close to the radio-frequency antenna region of card reader, which enters radio frequency field cutting magnetic induction
At this moment line mainly generates induced current by the inductance coil cutting magnetic induction line on card, at this point, LED light 61 shines, so,
LED card card face during transaction will form a preset luminous pattern.As it can be seen that when user uses the LED card
When piece carries out credit card transaction, induced current can be generated after carrying out electromagnetic induction between inductance coil and the induction coil of card reader,
The induced current is used to provide electric energy to LED light 61.Certainly, when LED card leaves the radio-frequency antenna region of card reader, inductance
There is no electromagnetic induction between coil and the induction coil of card reader, inductance coil no longer generates induced current, LED light 61 by
It is supplied in no power supply, to stop shining and restoring to the original state, realizes and secrecy processing is carried out to the personal information of LED card
Function brings different experience effect to user.
In the present embodiment, be additionally provided with resistance 64 on circuit substrate 6, resistance 64 can prevent when VCC power supply 63 with
When voltage difference between the output pin of programmable chip 62 is excessive, the phenomenon that LED light 61 may be breakdown, for LED light
61 play the role of protection.
Finally it is emphasized that the above is only the preferred embodiment of the present invention, it is not limited to this reality
With novel, for those skilled in the art, the utility model can have various change and change, all in the utility model
Spirit and principle within, any modification, equivalent substitution, improvement and etc. done should be included in the protection model of the utility model
Within enclosing.
