Brief description of the drawings
The accompanying drawing for constituting a part of the present utility model is used for providing being further understood to of the present utility model, and this practicality is new
The schematic description and description of type is used to explain the utility model, does not constitute to improper restriction of the present utility model.
In accompanying drawing：
Fig. 1 shows the structural representation of the utility model LED color control device.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
With reference to shown in Fig. 1, the utility model LED color control device is used to control outside three-color LED 0, including man-machine friendship
Mutual device 1, MCU2, the first A/D converter 3, the first current sampling circuit 4, the second A/D converter 5, the second current sampling circuit
6th, the 3rd A/D converter 7 and the 3rd current sampling circuit 8, MCU2 include a PWM, the 2nd PWM and the 3rd PWM, the first electric current
The one end of sample circuit 4 connects a PWM of MCU2, the R ends of the outside three-color LED 0 of other end connection, the second current sampling circuit 6
One end connects the 2nd PWM of MCU2, the G ends of the outside three-color LED 0 of other end connection, the connection of the one end of the 3rd current sampling circuit 8
3rd PWM of MCU2, the B ends of the outside three-color LED 0 of other end connection, the first A/D converter 3 is connected to MCU2 and the first electric current
Between sample circuit 4, the second A/D converter 5 is connected between MCU2 and the second current sampling circuit 6, the 3rd A/D converter 7
It is connected between MCU2 and the 3rd current sampling circuit 8.In the technical program, human-computer interaction device 1 is touch-screen.
To prevent being influenceed to make curent change by environment temperature etc., MCU2 is fed back to come real-time adjustment PWM using current sample
Electric current is reached the value of stabilization, RGB color is reached the color value of setting.Touch-screen is used simultaneously, electricity is set by touch-screen
Stream preset value (or the color value after electric current conversion), user can easily adjust.
From above-described embodiment as can be seen that advantage of the present utility model is：
Arbitrarily adjustment LED color can be conveniently realized on the touchscreen, objective interface is easy to operate.
Specific embodiment of the utility model has been described in detail above, but the utility model is not restricted to the above
The specific embodiment of description, it is intended only as example.To those skilled in the art, any equivalent modifications and substitute also all
Among category of the present utility model.Therefore, the impartial conversion done in the case where spirit and scope of the present utility model are not departed from
And modification, should all cover in the range of the utility model.
