Car Led Headlight Modification Knowledge (On)

Many car owners are dissatisfied with their car headlights, or they have been used for a long time and need to be replaced. At this time, car headlight modifications are often required. Of course, more importantly, due to the consideration of safe driving at night, more and more owners have joined the ranks of car headlight modification. It is very common to modify LED headlights for automobiles. Of course, it also includes the modification of halogen headlights and xenon headlights. China LED auto headlights manufacturers will introduce specific modification methods and precautions for you.

Car headlight classification:

Automotive headlights mainly include halogen, xenon, and LEDs. Among them, LED headlights are mainly used in low-end and mid-end cars. Xenon headlights are common in some high-end vehicles, and halogen headlights are only used in very few new vehicles.

Automotive LED headlights

LED is the abbreviation of Light Emitting Diode, commonly known as light-emitting diodes. They often appear in the role of light boxes, signboards and indicators and backlights of various electrical appliances. Important composition. Compared to xenon lamps and halogen lamps, LEDs have higher luminous efficiency and consume only 1/20 of the energy of halogen lamps. In addition, the cost of LED components has also been significantly reduced year by year, and the current cost and price are still at a rate of more than 20% per year decline.

Halogen headlights

Halogen lamps are actually a special type of incandescent lamps. The principle is that when a current is passed through the resistor, it will generate heat, and when the temperature is high enough, it emits blackbody radiation with a wavelength in the visible light band. There are generally two types of halogen lamps: iodine tungsten lamps and bromine tungsten lamps. When the incandescent lamp is lit, although the filament temperature does not exceed the melting point and boiling point of tungsten, a small amount of tungsten will still volatilize at high temperatures. When volatilized tungsten atoms meet the cooler bulb shell, it will condense and settle, and a layer of black tungsten film will be accumulated over time. Ordinary incandescent lamps have been used for a long time.

Xenon headlights

The full name of Xenon headlight is HID (High Intensity DischargeLamp) gas discharge lamp. It uses the supporting electronic ballast to instantly raise the 12V voltage of the car battery to a trigger voltage above 23KV. Stable light, providing stable automotive headlight lighting system.

Compared to ordinary halogen bulbs, xenon bulbs have two significant advantages:

On the one hand, xenon bulbs have three times the light intensity of ordinary halogen bulbs, but consume only two thirds of them;

On the other hand, xenon bulbs use almost the same light color as daylight, creating better visual conditions for the driver. Xenon lamps provide a wider range of light and greater light intensity, which greatly improves driving safety and comfort.

The Xenon lamp is composed of a light bulb, a stabilizer and a supporting line. Now they are all purchased in sets and can be used with the plug of the original car. However, the shape of the xenon headlight bulb is different from that of the original halogen bulb, and the focusing point will also change. Therefore, after the replacement of the xenon bulb, the original lamp bowl cannot effectively focus the light, so the light usually appears scattered In this way, the effect of the Xenon headlights is very small, but it is very dazzling when viewed from the outside of the car. Not only did not get the expected results, but it caused great safety risks at night. Most traffic accidents are Caused by lights.
