Embodiment
Below, describe automotive lighting provided by the utility model portion trouble-shooter in detail with reference to accompanying drawing.
Fig. 2 is made of battery 10, input part 20, Lighting Division 30, reference voltage generating unit 40, test section 50, control part 60 and expression portion 70 for expression comprises the automotive lighting portion control system block diagram of automotive lighting provided by the utility model portion trouble-shooter.
The following describes the function of each frame unit shown in Figure 2.
Reference voltage generating unit 40 responds described input voltages (IN) and output reference voltage (Vref).That is, be used to measure the supply voltage of supplying by battery 10.
Whether the lamp that test section 50 is used to detect Lighting Division 30 breaks down, and output detects voltage (SEN).For example, test section 50 can flow into the size of current of Lighting Division 30 and respond described size of current from input part 20 and export detection voltage (SEN) by detection.
Whether expression portion 70 notifies the described Lighting Division 30 of driver to break down by the described control signal of response (CON).Expression portion 70 can be by accomplished in many ways, can be by light-emitting diode formations such as (LED), and be installed on fascia etc. and inform visually whether described Lighting Division 30 breaks down, perhaps also can acoustically warn described Lighting Division 30 whether to break down by loud speaker formations such as (speaker).
Fig. 3 is the circuit diagram of the reference voltage generating unit 40 of expression the utility model automotive lighting portion trouble-shooter shown in Figure 2, is made of two resistance (R41, R42) and voltage stabilizing didoe (ZD).IN represents that input voltage, Vref represent reference voltage among Fig. 3.
The following describes circuit working process shown in Figure 3.
Two resistance (R41, R42) are used for distributing input voltage (IN) by predetermined value.Voltage stabilizing didoe (ZD) is used to prevent that reference voltage from surpassing predetermined voltage stabilizing value.
That is, reference voltage generating unit 40 shown in Figure 3, when input voltage (IN) surpasses predetermined value, the reference voltage (Vref) that output has predetermined voltage stabilizing value; When input voltage (IN) during less than predetermined value, output device has the reference voltage (Vref) of the magnitude of voltage that described input voltage (IN) distributed by two resistance (R41, R42).
Even supply voltage reduction that reference voltage generating unit 40 batteries 10 are supplied or other reasons and input voltage (IN) is reduced, and detection voltage (SEN) reduction that causes test section 50 to be exported thus, can prevent that also the driver from thinking that the lamp of Lighting Division 30 breaks down by mistake.
Fig. 4 is the block diagram of the test section 50 of expression the utility model automotive lighting portion trouble-shooter shown in Figure 2, constitute by resistance (R51), amplifier 52 and signal generation 54, and signal generation 54 by two resistance (R52, R53) and voltage stabilizing didoe (ZD) constitute.
The following describes the function and the course of work of unit in each frame shown in Figure 4.
Amplifier 52 is used to amplify the voltage at resistance (R51) two ends and exports the voltage of amplification.At this moment, resistance (R51) uses the resistance with fully little resistance for the action that does not influence Lighting Division 30.
Signal generation 54 responds the voltage of described amplification and exports and detect voltage (SEN).Promptly, utilize two resistance (R52, R53) voltage distribution with described amplification is a predetermined value, and work as the magnitude of voltage that distributed when surpassing predetermined voltage stabilizing value, output device has the detection voltage (SEN) of described predetermined voltage stabilizing value, when the magnitude of voltage of described distribution during less than predetermined voltage stabilizing value, output device has the detection voltage (SEN) of described distribution magnitude of voltage.
That is, whether the test section 50 of the shown in Figure 4 automotive lighting of the present utility model portion trouble-shooter electric current that flow into resistance (R51) by detection detects Lighting Division 30 and breaks down.If, constituting when part or all breaks down in one of Lighting Division 30 or the above lamp, the electric current by described resistance (R51) can diminish or not circulate.Voltage decreases when therefore, the both end voltage of described resistance (R51) can be more working properly than Lighting Division 30.Thus, judge by the both end voltage that detects described resistance (R51) whether the lamp that constitutes Lighting Division 30 breaks down.
And, by amplifying the voltage at described resistance (R51) two ends, and respond the described voltage that is exaggerated and export and detect voltage (SEN), thereby break down and also can detect even Lighting Division 30 has a part in the middle of a plurality of lamps and the described a plurality of lamps.
In other words, Fig. 2 is to shown in Figure 4 automotive lighting of the present utility model portion trouble-shooter, by utilizing test section 50 to detect the electric current that flow into Lighting Division 30 from input part 20, and respond described electric current and export and detect voltage (SEN), and utilize control part 60 to judge the size of described detection voltage (SEN), judge thus whether the lamp that constitutes Lighting Division 30 breaks down.Described judged result is warned the driver by expression portion 70.
And, preferably further comprise reference voltage generating unit 40, to be used to detect and output reference voltage (Vref) from input voltage (IN) size of described input part 20 outputs.At this moment, described control part 60 judges whether to break down by more described detection voltage (SEN) and described reference voltage (Vref), even other reasons such as the battery 10 supply voltage reduction of supplying and cause described detection voltage (SEN) to reduce can not think that also the lamp of Lighting Division 30 breaks down by mistake thus.
Though top reference preferred embodiment of the present utility model is described, but the technical staff author of technical field should be understood that under the situation of thought of the present utility model that does not break away from the petition to be put down in writing and scope and can carry out various modifications and changes to the utility model under the utility model.
In sum, whether the Lighting Division that automotive lighting provided by the utility model portion trouble-shooter can make the driver learn and be installed in automobile external breaks down, and whether this breaks down more useful for the stop lamp that judgement is installed in the automobile rear, and when described stop lamp is made of a plurality of lamps, also can detect even have only the part lamp to break down.
