Technical field
The utility model relates to the condenser motor vehicle signal lamp circuit monitoring device, belongs to machinery and electronic technology field, is particularly useful for the monitoring of motor vehicle signal lamp circuit.
Background technology
In order to improve driving and job security, power actuated vehicles such as automobile, trac. all are equipped with the signal lamp of reflection travel condition of vehicle such as backing-up lamp, brake lamp.Because most vehicles do not have perfect signal lamp circuit monitoring device, chaufeur can not in time be found faults such as tally circuit opens circuit, and the violating the regulations and traffic accident that causes thus happens occasionally.At present, more existing car light circuit checkers, but all there is corresponding deficiency, influenced it and applied.
The applying date is that the Chinese patent CN 2340644Y on August 25th, 1997 discloses a kind of " automobile lamplight automated watch-keeping facility ", is made up of three light-emitting diodes, three aerotrons, sample resistance etc.Whether sample resistance is connected in series to vehicle light circuit, normal through lighting different light-emitting diode reflection circuit.
The applying date is that the Chinese patent CN 2763129Y on December 10th, 2004 discloses a kind of " automobile lighting system real-time monitoring device "; Form by controller, supervision indicator lamp etc.; Controller is made up of solenoid, dry-reed tube; Solenoid is connected in series to vehicle light circuit monitoring open circuit fault, and it is normal to keep watch on the bright expression car light of indicator lamp circuit.
Above-mentioned utility model all need be connected in series subelement to vehicle light circuit, wiring inconvenience.
The applying date is that the utility model patent ZL200820016881.6 on January 22nd, 2008 discloses " a kind of motor vehicle signal lamp circuit monitoring device "; Form by cond, current-limiting resistance, discharging resistance and two light-emitting diodes, utilize the brightness of two light-emitting diodes to change the realization circuit monitoring.This patent adopts two light-emitting diodes lamp of giving instruction, and motor vehicle signal lamp or circuit just often light-emitting diode (5) is bright, light-emitting diode (5) did not work when open circuit fault was arranged, and influenced the warning effect.
Summary of the invention
In order to overcome the problem of wiring of above-mentioned car light circuit monitoring device and warning effect aspect, the utility model provides the condenser motor vehicle signal lamp circuit monitoring device.
The technical scheme that its technical matters of the utility model solution is taked is: the utility model comprises cond, current-limiting resistance, acceleration diode, light-emitting diode and discharging resistance; Current-limiting resistance, quicken after the diode parallel connection and capacitors in series; Parallelly connected after light-emitting diode, the discharging resistance series connection with cond, quicken the anode of diode and the anode of light-emitting diode and link to each other.Current-limiting resistance be used for limiting capacitance device charging current, reduce the utility model power consumption; Quicken diode and be used for accelerating cond through the motor vehicle signal lamp circuit discharge.
The beneficial effect of the utility model is that the utility model circuit is connected in parallel easy-to-connect with the motor vehicle signal lamp that needs monitoring; Change according to motor vehicle signal lamp switch connection and the brightness of breaking off the same light-emitting diode in back, realize the monitoring of motor vehicle signal lamp circuit.
Description of drawings
Fig. 1 is the schematic circuit diagram of the utility model.
Fig. 2 is the utility model and the motor vehicle signal lamp circuit connection diagram that needs monitoring.
1-current-limiting resistance among the figure, 2-quickens diode, 3-light-emitting diode, 4-cond, 5-discharging resistance, 6-safety device, 7-switch, 8-motor vehicle signal lamp.
The specific embodiment
The utility model comprises cond 4, current-limiting resistance 1, quickens diode 2, light-emitting diode 3 and discharging resistance 5; Connect with cond 4 in current-limiting resistance 1, acceleration diode 2 parallel connection backs; Parallelly connected after light-emitting diode 3, discharging resistance 5 series connection with cond 4, quicken the anode of diode 2 and the anode of light-emitting diode 3 and link to each other.
As shown in Figure 2, the utility model circuit two ends and the motor vehicle signal lamp 8 that needs monitoring are connected in parallel, the brightness that switches on and off back light-emitting diode 3 according to vehicle signal light switch 7 changes, and realizes the monitoring of motor vehicle signal lamp circuit.
If motor vehicle signal lamp 8 and safety device 6, switch 7 and circuit are all normal; When switch 7 is connected; Power supply gives cond 4 chargings through current-limiting resistance 1; The electric current of light-emitting diode 3 and brightness are along with the terminal voltage of cond 4 improves enhancing gradually, and after the terminal voltage of cond 4 no longer raise, it is maximum that the brightness of light-emitting diode 3 reaches; After switch 7 breaks off; Cond 4 is on the one hand through quickening diode 2 and current-limiting resistance 1, motor vehicle signal lamp 8 discharges; Simultaneously through light-emitting diode 3 and discharging resistance 5 discharges; Because motor vehicle signal lamp 8 resistance are very little, cond 4 discharges light-emitting diode 3 deepening rapidly immediately, are extinguished rapidly.
If light-emitting diode 3 does not work all the time when switch 7 is connected, safety device 6, switch 7 or power circuit generation open circuit fault are described; After switch 7 connection light-emitting diodes 3 are lighted; If can not extinguish rapidly along with switch 7 breaks off light-emitting diode 3; Explain that motor vehicle signal lamp parallelly connected with the utility model 8 or circuit have open circuit fault; And switch 7 breaks off back light-emitting diodes 3 and extinguishes slowly more, explains that the branch road of motor vehicle signal lamp 8 or circuit generation open circuit fault is many more.
