What are the signs that the xenon lamp ballast is broken?

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

The failure of the xenon lamp ballast has the following characteristics: 1. The bulb does not light up, and the replacement of a new bulb does not light up, which indicates that the ballast may be broken. 2. The xenon lamp can be lit normally, but the fault alarm light of the instrument panel is also on, which means that there is a problem with the ballast.

3. The xenon lamp flashes or often goes out or the upper and lower lights do not turn on at the same time, which also indicates that the ballast is faulty.

When the ballast squeaks during operation, this is the sound of the transformer inside the ballast, which is normal. However, if the sound is too loud, it can be heard outside with the cover closed, which means that the transformer still has quality problems, please rest assured that this does not affect the use, if it is serious, replace the ballast.

A method for judging whether the ballast is damaged.

1. When the xenon lamp is not lit, unscrew the bulb that is not lit and replace it with a new bulb, if the new bulb is on, it is the problem of the bulb; If it doesn't light up, there is something wrong with the ballast.

2. Check the interface of the ballast harness, if the socket is loose or the line is problematic, the ballast will fail; If the plug is normal, then it is a problem with the ballast.

The ballast is an important component of the xenon lighting system, also known as the HID electronic ballast. When the xenon lamp doesn't come on, is the bulb broken or the ballast broken? Many car owners will have this kind of doubt, and the following will teach you how to judge that the ballast is broken.

A method for judging whether the ballast is damaged.

1. When the xenon lamp is not lit, change the unlit bulb to unscrew off and replace it with a new bulb, if the new bulb is on, it is the problem of the bulb; If it doesn't light up, there is something wrong with the ballast.

2. Check the interface of the limb ballast harness, if the socket is loose or the line is problematic, the ballast will fail; If the plug is normal, then it is a problem with the ballast.

Xenon lamp ballast fault characteristics

Fault 1: After installation, the headlights work normally, but the instrument panel headlight fault alarm light is on.

This is a very common fault, which may be due to the mismatch between the xenon lamp and the ballast, and the xenon lamp and the ballast of the same voltage should be selected.

Fault 2: After installation, the bulb flashes or often goes off or the left and right lights are not on at the same time.

Most of the causes of this failure are line problems, which may be caused by excessive starting current of the ballast. At this time, it is necessary to check whether the working current of the headlight line is normal.

Is the yellowing of the xenon lamp a bad stabilis? Yellowing of the xenon lamp is not a damage to the ballast. The following is an extension of information about xenon lamps:

1. Definition: Xenon lamp, also known as HID gas discharge headlamp in the field of automotive lamps. It replaces the traditional tungsten filament with high-pressure xenon gas encapsulated in a quartz tube, providing higher color temperature and more concentrated illumination.

2. Color temperature: The color temperature of xenon lamps is between 4000K and 6000K, which is much higher than that of ordinary headlight bulbs. It has high brightness, the light color of the 4300K xenon lamp is white and yellowish, due to the low color temperature, the visual effect is yellowish, and the penetration of the light is stronger than that of the lamp with high color temperature, which can improve the driving safety at night and in foggy weather.

3. Power saving: Xenon lamps are more power-saving, most of the xenon lamps are 35W, and the light emitted is more than 3-5 times that of 55W halogen lamps, which greatly reduces the load of the power system, saves 40% of power loss, and improves the performance of electric lamps accordingly. @2019

The ballast of the xenon lamp is an indispensable part of the HID (High Pressure Gas Discharge Lamp, in this case, the xenon lamp).

HID is mainly composed of bulbs, ballasts, power adaptation lines and accessories. The moment the xenon lamp power is turned on, the ballast instantly boosts the 12V voltage on the car to 23000V, and uses this high-intensity voltage to activate the HID bulb to produce strong light between the two poles, so that the bulb achieves high brightness illumination.

The volume of the xenon lamp ballast is very small, only a quarter of an ordinary computer optical drive, with the development of modern manufacturing technology, now Olatun has introduced a new ultra-thin ballast, the size is only 72mm*61mm*13mm, only 13mm thickness.
