The advantages and disadvantages of xenon lamps Introduction to the components of xenon lamps
Xenon lamps are often used in car lights, but they can also be used in other places. The main thing is that they are more transported. Maybe many people don't understand it. What are the advantages and disadvantages of xenon lamps? Next, BENWEI LIGHTING will explain it to you, and then there will be an introduction to the components of the xenon lamp to share with you, let's take a look.

Advantages and disadvantages of xenon lamps:
Compared with other types of car lights, HID xenon lamps have their own advantages and disadvantages. For details, let’s take a look at the following detailed introduction. I hope it will be helpful to everyone:
Advantages of hernia lamp:
1. The color temperature of xenon lamps ranges from 3000K to 12000K. The color temperature of 6000K is similar to sunlight, but contains more green and blue components, so it presents blue-white light. This blue-white light greatly improves road signs and signs. The brightness.
2. The brightness efficiency of HID is three times higher than that of halogen lamps, which has obvious effect on improving the visibility of driving at night and in fog.
3. The luminous flux emitted by the xenon lamp is more than twice that of the halogen lamp. At the same time, the efficiency of converting electric energy into light energy is also 70% higher than that of the halogen lamp. Therefore, the xenon lamp has a relatively high energy density and light intensity. The improvement also effectively expands the visual range in front of the car, thereby creating safer driving conditions.
4. Power saving 1/2, halogen lamp consumes more than 60W of power, xenon lamp only needs 35W of power.
5. Because the xenon lamp has no filament, it will not cause the problem of scrap due to broken filament. The service life is much longer than that of the halogen lamp. The service life of the xenon lamp is equivalent to the entire operating time of the car's average life cycle.
6. Once the xenon lamp fails, it will not be extinguished instantaneously, but will be extinguished by gradually dimming (or quickly lit), so that the driver can win time in the dark driving and stop urgently.
Disadvantages of hernia lamp:
1. The light-gathering property is not good, and there are two reasons for not light-gathering:
(1) Improper collocation of bulbs and lamp cups.
(2) The installation is not in place or the debugging is not good.
2. The fault light is on because the bulb of the original car has high power consumption (55W) and the power of the xenon lamp is low (35W), so after the modification, its power is not enough and the alarm is generated. As a xenon lamp, its starting current is 8A, while the original car It is 6.2A Kaicheng, so the circuit setting of the original car does not match, you need to go to the 4S shop to change the circuit mode.
3. Automatic flameout is caused by electromagnetic interference due to excessive starting current. This can be used to keep the ballast away from the engine or change to a low-current starting ballast during installation.
4. This problem is mainly reflected in the seahorse car series, especially the 323 and other cars, because it is powered by the dimming circuit and takes power directly from the battery. The power supply of the headlight circuit is too light, so it does not light up after the xenon lamp is installed. Install the loop, otherwise the high beam indicator will not turn on. After installing the telescopic lamp, if the loop is not installed correctly, it will easily cause the lack of high beam power supply and cause the light to shake, especially the telescopic lamp below 1,000 yuan, which is far away on uneven roads. The light jitter is more obvious, you can find a professional to install a circuit with the correct voltage, or buy a xenon lamp above 1,000 yuan to solve it.

Introduction to the components of the xenon lamp:
The principle of the xenon lamp is to fill the UV-cut anti-ultraviolet crystal quartz glass tube with a variety of chemical gases, most of which are xenon and iodide, and then pass the ballast to the car. The upper 12 volt DC voltage is instantly pressurized to a voltage of 23,000 volts, and the xenon electrons in the quartz tube are excited to dissociate through the high-voltage amplitude, and a light source is generated between the two electrodes. This is the so-called gas discharge. The white super-strong arc light produced by xenon gas can increase the color temperature of the light. It is similar to the sun's rays in daylight. The current required for HID operation is only 3.5A, the brightness is three times that of traditional halogen bulbs, and the service life is longer than traditional The halogen bulb is 10 times longer.
Generally speaking, HID xenon lamp consists of lamp holder (xenon bulb), electronic ballast (also called ballast, voltage stabilizer, adaptor, etc.), wire group control box, etc.:
1. Lamp holder: If you observe carefully, you will find that the HID xenon lamp holder has no filament. The current between the electrodes is used to promote the collision of xenon molecules to produce brightness. There is no problem of tungsten filament burnout (there is no tungsten filament. Xenon lights);
2. Programmable ballast: Using the 12V DC voltage of the battery, after a series of conversion, control, protection, boosting, frequency conversion and other actions, an instantaneous ignition high voltage of 23000V is generated to ignite the lamp holder, and then maintain 85V after lighting. AC voltage, starting current is about 8A, working current is about 4A. In 2013, the most intelligent electronic ballast launched on the market is the "program-controlled ballast", which uses modern computer technology to compile specific programs and implant chips to control the circuit, so that it can complete detection, calculation and automatic matching of xenon lamps, thereby Make the collocation between the two achieve the best performance.
3. Wire group: generally made of flame-retardant materials. By increasing the cross-sectional area of the power cord, the current passing capacity is improved, and the normal operation of the HID xenon lamp is ensured. Some H4 models are equipped with a relay wire group for work control. .
