Device brightness regulating circuit is operated relatively complicated using manually controlling.
Utility model content
The utility model is to overcome above situation insufficient, it is desirable to provide a kind of technical solution that can solve the above problem.
A kind of display brightness adjusting control circuit, including hold manually, controller, outer lumenmeter, rheostat, backlight and
The input terminal of interior lumenmeter, the controller is connect with manual end, outer lumenmeter and interior lumenmeter respectively by conducting wire, the control
The output end of device processed is connect by conducting wire with backlight, and rheostat is equipped between controller and backlight.
As a further solution of the present invention: the manual end includes mode conversion key and brightness regulating button,
Middle mode conversion key switching automatic mode and manual mode, brightness regulating button include up-regulation button and two kinds of down button.
As a further solution of the present invention: the detection probe of the outer lumenmeter is mounted on the back side of display,
Face the rear area of display.
As a further solution of the present invention: the rheostat is automatic varistor.
As a further solution of the present invention: the backlight is LED light source, it is equipped in front of backlight interior
The detection probe of lumenmeter.
Compared with prior art, the utility model has the beneficial effects that
The utility model can simplify the control adjusted to display brightness, can be certainly without using the operation that person is excessive
The dynamic light for issuing suitable light intensity, effectively protects the eyes of user.
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the utility model structure diagram.
In figure: holding 1, controller 2, outer lumenmeter 3, rheostat 4, backlight 5 and interior lumenmeter 6 manually.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of display brightness adjusting control circuit, including hold 1 manually,
The input terminal of controller 2, outer lumenmeter 3, rheostat 4, backlight 5 and interior lumenmeter 6, the controller 2 is distinguished by conducting wire
It being connect with manual end 1, outer lumenmeter 3 and interior lumenmeter 6, the output end of the controller 2 is connect by conducting wire with backlight 5,
And rheostat 4 is installed between controller 2 and backlight 5.
The manual end 1 include mode conversion key and brightness regulating button, wherein mode conversion key switching automatic mode and
Manual mode, brightness regulating button include up-regulation button and two kinds of down button.
The detection probe of the outer lumenmeter 3 is mounted on the back side of display, faces the rear area of display.
The rheostat 4 is automatic varistor.
The backlight 5 is LED light source, is equipped with the detection probe of interior lumenmeter 6 in the front of backlight 5.
The working principle of the utility model is:
The utility model is outer under mode with an automatic light meter by holding 1 switching hand-operating light mode and mode with an automatic light meter manually
Lumenmeter 3 monitors the brightness of external environment, which is passed to controller 2.Controller 2, which is computed, obtains light filling intensity, and
It the result is converted to control signal and passes to rheostat 4, is adjusted by rheostat 4 and flows through the electric current of backlight 5, controlled with this
The light intensity of backlight 5, and interior lumenmeter 6 is installed at backlight 5, the light intensity data of backlight 5 is fed back to control by interior lumenmeter 6
Device 2 processed.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting
Related claim.
