Car Head Lamps Different Types of Head Lights apart from halogen and LEDs, there are many options

Today we have advanced so much in technology that we are also getting to see automatic lights in cars. But there was a time when cars were fitted with carbide gas-burning lights. Let us know about the headlights used in cars at present.

Headlights are a very important part of the car . These are the eyes of the car in a way. Without these it is impossible to drive a car at night or in bad weather.

Today we have advanced so much in technology that we are also getting to see automatic lights in cars. But there was a time when cars were fitted with carbide gas-burning lights. Let us know about the headlights used in cars at present.

Halogen

Halogen headlamps are most commonly used in our country. This is because they are cheaper than other types of headlamps.

These headlamps consist of a capsule-shaped glass filled with halogen gas and tungsten filament.

When these are turned on, electricity passes through the tungsten filament which creates heat inside and the filament inside the bulb starts glowing. Halogen headlamps give off yellow light.

Xenon or HID headlamps

Xenon or HID (High Density Discharge) headlamps are like the CFL or compact fluorescent lights we used in our homes before the advent of LEDs.

Instead of filament, they contain xenon gas. When high voltage is passed through the two electrodes, the gas glows.

They emit more light than halogens but take some time to heat up. HID headlamps have blue-white illumination.

LED

Today more and more automobile manufacturers are adopting LED lighting in their cars. LED is called Light Emitting Diode.

These are very prevalent today as compared to other types of headlamps. They do not have any kind of fire and they use very little electricity.

They can also be changed to the smallest size. For this reason they are used in most DRLs (Daytime Running Lights).

Matrix Headlamps

Matrix headlamps are called adaptive LEDs. In these, many different LEDs are used with one camera.

Its camera keeps a constant eye on the vehicles coming from the front. As soon as a car is seen coming in front, its system turns off an LED that illuminates that car so that the front is not dazzled.

This does not require the driver to switch to low-beam, as it is automatic .
