Description

HID xenon lamp comprehensive detector

technical field

The invention relates to a test tool for the ignition voltage of a motor vehicle lighting ballast and a fire arc containing xenon lamp, specifically a HID xenon lamp comprehensive detector.

Background technique

There are many reasons why the xenon lamp cannot work, such as electric leakage of the lamp wire, insufficient high voltage of the ballast, insufficient fire arc, failure of subsequent current supply, automatic power-off protection caused by overheating, and there is no special maintenance master in the after-maintenance market. It is judged that the complete replacement of the ballast and the xenon lamp will cause a lot of pressure on the manufacturers and dealers, and it is also not conducive to the after-sales service of the products.

Contents of the invention

The purpose of the present invention is to provide a HID xenon lamp comprehensive detector, which has the function of quickly detecting various indicators of the ballast.

The present invention is realized by the following technical scheme: the HID xenon lamp comprehensive detector consists of a host, an ammeter, a voltmeter, a control module, an indicator light, a switch, a power socket, a discharge iron, a scale, a combustion chamber, a garbage port, and a light bulb wire , Stabilizer line composition.

It is characterized in that ammeter and voltmeter are installed on the inclined panel of the main engine, a combustion chamber is designed on the front panel, the switch is connected with the signal terminal of the control module, the output terminal of the ammeter and the positive terminal of the voltmeter are connected in parallel with the power input of the control module, The negative pole of the voltmeter, the negative pole of the power base and the negative pole of the power supply line are connected in parallel; The fifth and sixth pins of the module are connected, the seventh and eighth pins of the control module are respectively connected with two discharge irons, the indicator light is connected with the feedback terminal of the control module, and one is installed on the left and right sides of the combustion chamber. Discharge iron, a ruler is installed at the upper position corresponding to the discharge iron on the left.

Connect the positive and negative poles of the power input line of the ballast high-voltage discharge detector to the 12V DC output power supply, the output line of the ballast to the ballast line of the ballast high-voltage discharge detector, and the power line of the ballast to the power base , the lead wire of the xenon lamp is plugged into the bulb wire.

First loosen the fastening screws on the discharge iron, adjust the distance between the discharge irons, measure with a ruler, the distance between the two discharge irons is 7mm, then fasten the screws on the discharge irons, tear off a corner of a newspaper at random The newspaper is stuck in the paper jam slot of the combustion chamber, press the switch once, the control module receives the signal, firstly:

In the first step, the control module conducts the ballast output line and connects the pin 7 and pin 8 of the control module,

The second step is to turn on the power of the power base, and the ballast will work.

1. The discharge iron must emit sparks, if not, it indicates that the high-voltage energy of the ballast is insufficient, and the ballast must be replaced;

2. There is spark, but the discharge time is less than 2 seconds, because the capacity of the time capacitor is too small, the ballast must be replaced;

3. There is a spark, and the control module switches on the electric power of the power base 3 times in a row every 1 second, so that the ballast is turned on 3 times. At this time, the electric arc generated by the ballast must ignite the newspaper, and the burnt paper ash passes through Clean out the garbage port below, if not, it indicates that the high-voltage fire arc of the ballast is not strong enough to spread the xenon gas rapidly, affecting the lighting effect, and the ballast must be replaced;

4. If there is no high voltage and the current is as high as 10 amperes, it is an internal short circuit of the ballast, and the ballast must be replaced;

For the above four points, the control module sends 12V voltage through the feedback terminal, and the red indicator light is on;

The third step, when the above two steps are successfully passed, the control module cuts off the power of the power base, and at the same time disconnects pins 7 and 8, and turns the output line of the ballast to connect with pins 3 and 4 , to complete the connection between the output wire of the ballast and the xenon lamp; then, turn on the power socket again,

1. When the ballast works, the xenon lamp flashes once and then goes out, indicating that the subsequent current supply of the ballast is insufficient, and the ballast must be replaced;

2. If it is on, the pointer of the ammeter should be about 3.5A, and it will drop to about 3A after one minute. If the current is too high, it will cause the vehicle to run out of power or the xenon lamp will fail to start. It is necessary to replace the ballast or increase the wiring harness Or increase the output power of the rectifier to match the power of the ballast;

For the above two points, the control module sends 12V voltage through the feedback terminal, and the red indicator light is on;

At the same time, the voltage of the voltmeter should be within 70V~110V. If it exceeds this voltage, the internal tube pressure of the xenon bulb body is too high, which will cause the ballast to work for a certain period of time. Turn off the power to prevent the transformer from burning. , the control module sends 10V voltage through the feedback terminal, and the yellow indicator light is on. In this case, the xenon lamp must be replaced to reduce the tube pressure and meet the working requirements of the ballast;

Step 4: When the tested ballast works for 30 minutes, the current drops below 2.8A, indicating that the temperature of the transformer inside the ballast is too high, and the ballast must be replaced, or the ballast must be installed in a place with good ventilation in the vehicle. to facilitate heat dissipation;

Step 5: After the tested ballast works for a certain period of time, the tube pressure of the xenon lamp at this time is within the normal range, and the ballast stops working, indicating that the control part of the ballast is damaged, and the ballast must be replaced , at this time, the control module sends 12V voltage through the feedback terminal, and the red indicator light is on;

After passing the test for 40 minutes and completing the above steps, the control module cuts off the power of the power socket and resets all connecting pins. At this time, the control module sends a voltage of 8V through the feedback terminal, and the green indicator light is on, indicating that the tested The ballast and xenon lamps are normal.

The beneficial effect of the present invention is that it has the functions of effectively detecting the ignition voltage of the ballast, the supply of the fire arc and the subsequent current, and the tube voltage of the xenon lamp bulb, and the control module sends different voltages to the indicator according to the detected results. Light, to light red, yellow, green three LED lights to indicate different states.
