Description
Technical field
The utility model belongs to LED lighting technical field, relates in particular to a kind of lighting control circuit of vehicle-mounted button.
Background technology
Along with economic and scientific and technological development, automobile is more and more, requires more and more highlyer, particularly universal in the family of car Yi most cities, makes people require further raising to the various aspects of performance of car, and the requirement of body light light is also more come also to pay attention to.Automobile is often by day or when night occurs, luminance difference in vapour environment inside car is larger, vehicle mounted multimedia panel and button light remain unchanged substantially, this single brightness shows the instructions for use that cannot meet varying environment, and cause the lamplight brightness of vehicle mounted multimedia and body light light by inharmonious, directly affect sensory effects.For example, daytime is bright and clear, and display screen and button need to have enough brightness assurance displaying contents to see clearly; When night or car steering enter tunnel, very dark in automobile, the brightness of display screen and button need to be turned down, not dazzling to guarantee demonstration.
In most automobile, except light can not regulate automatically, in control button, use the LED lamp of the same model of same production batch also to have the difference of lamp brightness, therefore, in vehicle mounted multimedia, because the operating current of button light (LED) is constant substantially, controls the resistance of LED lamp current and also fix in same production batch.Based on cost factor, consider, the LED lamp of vehicle-mounted upper use generally has 3 ~ 4 brightness degrees, and in same grade, LED brightness also can be fluctuateed within the scope of certain.Even if the brightness of LED lamp is in same grade, self brightness value also can there are differences, and causes, when vehicle-mounted panel has a plurality of button, just there will be the phenomenon of brightness disproportionation.Owing to controlling the electric current of LED lamp, can not change, the brightness of button can not change substantially.When body light luminous environment occurs that light and shade changes, the lamplight brightness of vehicle mounted multimedia and body light light, by inharmonious, affect visual effect.
Summary of the invention
In view of this, the utility model provides a kind of and can regulate in real time with the variation of environment inside car brightness, and can coordinate the lighting control circuit of the vehicle-mounted button of multimedia light and body light light.
The design that the utility model is taked is: a kind of lighting control circuit of vehicle-mounted button, comprise the LED lamp, light sensor and the processor that are arranged in button, described light sensor comprises light sensor device R1 and light sensor R2, and light sensor R1 is all connected with processor with light sensor R2 and LED lamp; Light sensor R1 is arranged on by LED lamp, and light sensor R2 is arranged on the control panel in car.
As improvement of the present utility model, described light sensor is photo resistance.
As improvement of the present utility model, described processor is single-chip microcomputer.
As improvement of the present utility model, described LED lamp is light-emitting diode.
Compared with prior art, the vehicle-mounted LED display screen that the utility model can make and press key lamp brightness more even, the impact of the difference that can effectively weaken LED lamp self brightness on button; Light and the body light light of vehicle mounted multimedia are coordinated more, and can be regulated in real time according to the variation of environment inside car brightness the brightness of the light of button, sight equation when minimizing human eye is watched LED display and button, improves comfort level.

Embodiment
In order to allow those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further elaborated.
As depicted in figs. 1 and 2, a kind of lighting control circuit of vehicle-mounted button, comprises the LED lamp, light sensor and the processor that are arranged in button.Described LED lamp is light-emitting diode, described light sensor is that described processor is for receiving the strong and weak signals of light sensor output the single-chip microcomputer that the luminosity information of monochrome information in car and LED is processed, controlled for detection of the photo resistance R1 of body light brightness strong and weak signals with for detection of the photo resistance R2 of the strong and weak signals of the luminosity of LED.Light sensor device R1, light sensor R2 are all connected with processor with LED lamp; Control panel B is installed on the master station in car, control panel B is provided with control button C that can leaded light, button C derives the LED light that is positioned at the bottom of button C, the other light sensor R1 that is provided with of LED lamp, the control panel B that light sensor R2 is arranged in car is upper, the power of lamplight brightness in inspection vehicle.
Photo resistance R1 feeds back to respectively single-chip microcomputer by lamplight brightness strong and weak signals in inspection vehicle and photo resistance R2 by the strong and weak signals that detects the luminosity of LED, single-chip microcomputer is analyzed judgement according to the ambient brightness information of photo resistance R1 and photo resistance R2 detection, after single-chip microcomputer analysis, send LED control signal, adjust in real time the control electric current of LED lamp, change the brightness of LED lamp, the brightness of LED lamp and environment inside car are adapted, improve the comfort level of light.Adopt body light luminous intensity to detect and button in the mode that detects of the brightness such as LED improved the precision that environment inside car detects, make light coordination, reduced the sight equation of environment inside car.
In order to solve the brightness of LED lamp in same grade, the problem that self brightness value also can there are differences, the utility model employing LED lamp as shown in Figure 3 and the circuit of photo resistance connection.As shown in Fig. 3 circuit, in the input access series connection photo resistance of circuit, the output of photo resistance is in parallel with the base stage of four triodes respectively, a photo resistance of emitter series connection of each triode, the other end ground connection of photo resistance; The output of the collector electrode place in circuit in parallel of each triode; Between the collector electrode of the first two triode Q1 and output, connect successively photo resistance R3, LED 1 and LED 2 and the photo resistance respectively in parallel of the two ends of this photo resistance R3, LED 1 and LED 2; Between the collector electrode of latter two triode Q2 and output, connect successively photo resistance R4, LED 3 and photo resistance R5, in the photo resistance R4 of this series connection and the two ends of LED 3 photo resistance respectively in parallel; The voltage-stabiliser tube of having connected between the node connecting in input and photo resistance, the anodal access node of the first voltage-stabiliser tube, negative pole accesses the negative pole of the second voltage-stabiliser tube, the cathode node of the second voltage-stabiliser tube.Described circuit input end is connected with single-chip microcomputer the corresponding interface with output.
LED lamp is directly connected with photo resistance, by the photo resistance being connected with LED lamp, the brightness that monomer LED lamp sends is connected photo resistance by it and senses that rear change resistance value adjusts the electric current of connection LED lamp, change the brightness of LED lamp, make whole light reach balanced, the brightness disproportionation weighing apparatus of having avoided monomer LED lamp, affects visual effect.
It is more than preferably implementation of the utility model; it should be noted that; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding changes and distortion according to the utility model, but these changes and distortion all should belong to the protection range of the appended claim of the utility model.
