Abstract
The utility model relates to a regulating device, particularly a regulating device capable of regulating the brightness degree of an instrument lamp of an automobile. The utility model comprises an instrument lamp and a control circuit of the instrument lamp, wherein a power supply circuit is connected with a regulating control circuit, which forms the control circuit. The regulating control circuit is connected with a light emitting diode. A variable resistor is arranged in the regulating control circuit. The utility model provides a regulating device capable of regulating the brightness degree of the instrument lamp according to radial strength outside an automobile window, and the structure of the utility model is simple. The utility model solves the technical problems that the brightness degree of the existing instrument lamp can not be regulated, and the use of the instrument lamp is not convenient existing in the prior art.
Description
Technical field
The utility model relates to a kind of control apparatus, relates in particular to a kind of control apparatus that can regulate the bright-dark degree of auto meter lamp.
Background technology
On automobile driver seat, display automobile speed is arranged, the instrument of automobile trapped fuel amount etc.Clearly know the situation of the each side of automobile for convenience under the situation that driver's light outside vehicle window is darker, usually be provided with light-emitting diode at the instrument place, by lighting the instrument data presented that light-emitting diode makes the driver read automobile, thereby understand the running state of automobile.But the brightness of existing instrument display lamp has just configured when automobile dispatches from the factory, and the bright dark degree of lamp is immutable.No matter the brightness outside the vehicle window is how, instrument panel lamp all is identical, like this can not be energy-conservation, and under the situation that light is very dark outside vehicle window, light can not change simultaneously.
Summary of the invention
The utility model has mainly provided a kind of simple and reasonable, can come the control apparatus of the light and shade of regulation meter lamp according to the power of the outer light of vehicle window; It is non-adjustable to have solved the instrument panel lamp shading value that exists in the prior art, the technical matters that can not conveniently use.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of light and shade control apparatus of auto meter lamp, comprise instrument panel lamp and instrument panel lamp control circuit, described control circuit is that power circuit is connecting the regulating control circuit, the regulating control circuit is connecting light-emitting diode, is provided with variable resistance in the described regulating control circuit.In the regulating control circuit, variable resistance is set, thereby regulates electric current, and then regulate the bright-dark degree that is connected ohmically light-emitting diode through this branch road.The bright-dark degree of instrument panel lamp can regulate according to the power of the light outside the vehicle window and driver's oneself eyesight level, has made things convenient for driver's use.
As preferably, described regulating control circuit is provided with the branch road of at least one, and branch road is that resistance is connecting light-emitting diode, and each branch road all is connected in parallel.
As preferably, the resistance in the described regulating control circuit is continuous adjustable resistance.The light and shade of lamp is a continually varying, brightens gradually or deepening gradually.
As preferably, the resistance in the described regulating control circuit is the stepping adjustable resistance.The stepping adjustable resistance makes that the variation of lamp is that stepping changes, and whenever stirs one grade, and the brightness of lamp changes once.
Therefore, the utlity model has simple and reasonablely,, so both saved resource, also made things convenient for the demand adjustment of driver simultaneously, make that driving is more smooth and easy according to oneself according to the bright dark degree that the intensity of the outer light of vehicle window is come the regulation meter display lamp.
Description of drawings:
Fig. 1 is a kind of electrical block diagram of light and shade control apparatus of auto meter lamp.
Fig. 2 is a kind of scheme drawings such as instrument of light and shade control apparatus of auto meter lamp.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Shown in attached Fig. 1 and 2, a kind of light and shade control apparatus of auto meter lamp comprises the circuit of instrument panel lamp 1 and control instrument lamp.The circuit of described control instrument lamp is that power circuit 5 is connecting regulating control circuit 6, and regulating control circuit 6 is connecting light-emitting diode 2.In regulating control circuit 6, be provided with variable resistance, change electric current by regulating variable-resistance resistance, thereby change the bright-dark degree of light-emitting diode by branch road 4.Be resistance 3 on each bar branch road 4 and link to each other, be provided with at least one such branch road 4 in the control circuit with light-emitting diode 2.
The motorist can adjust the bright dark degree of instrument panel lamp according to the power of the outer light of vehicle window and the hobby of oneself.
Claims (4)
