How to choose the one that suits you better?

If a person has a pair of beautiful big eyes, it will certainly improve his appearance level a lot of scores, also for the car, a pair of bright headlights, just like its eyes, the level of appearance depends on it. Many vehicles have different light sources depending on the configuration. In general, the common light sources are halogen, xenon and LED. So, what's the difference between the three sources of light? Which one should you choose for your daily life? Xiaobian today to everyone said.

1. halogen light source

Halogen light source is one of the most common light sources for car lamps. Generally speaking, it is called halogen headlamp, because the main component inside the lamp body is tungsten, so it is also called tungsten halogen lamp or quartz lamp. Evolved from ordinary incandescent lamps.

Principle: used in vehicle head lamp on the halogen lamp inside the lamp body into the halogen gas, similar iodine, bromine, and so on medium gas, due to the tungsten filament at high temperature for sublimation, halogen gas at this time would have a certain chemical reactions and sublimation of tungsten, tungsten to solidification has become gas could continue to use in the original tungsten filament, similar to the energy balance effect that the service life of the lamp to a certain time.

Features: simple structure, low manufacturing cost, near brightness is ok, the light is soft and even, far brightness is poor, because the light is yellow, the penetration effect is good in rain and fog weather. However, low overall brightness and short service life are the biggest drawbacks of halogen headlamps.

2. Xenon light source 

First popularize a common sense, there are many car fans friends will be "xenon" said "hernia". Here must remember, "xenon" is a chemical nature of the very inactive chemical gas, "hernia" is a commonly known as "intestinal gas" a disease! Remember that! Remember that! Remember that!

Principle: xenon headlights in the automotive field have a very high name called "HID gas emission point headlights." The principle of luminescence is that the high-voltage discharger between the two electrodes generates electric arc luminescence. Instead of the traditional tungsten filament, a quartz tube filled with high-voltage xenon gas is used to emit light with higher color temperature and more concentrated light.

Features: more complex structure than halogen headlamps, higher manufacturing cost. It is usually three times brighter than a normal halogen headlamp. It also has a long service life.

3. LED light source

When leds were first introduced, mostly to mobile phones, computers and television screens, none of the electronic devices that carried them were cheap. LED light source due to energy saving, long service life, and the characteristics of soft light is not dazzling gradually began in the office, home, and other places with light popularity. Then I got on the bus.

Principle: LED is an acronym, which translates as light Emitting Diode. This is a solid-state semiconductor device that is capable of converting electrical energy directly into visible light. Depending on the material of the inorganic semiconductor, the visible light emitted varies in color.

Features: power saving, long life, high brightness. But manufacturing costs are the highest of the three options. Therefore, the LED light source will not be chosen as the headlamp light source in general vehicle models. It is more used in daytime traffic lights. Maintenance costs are under control.

How to choose?

First look at the budget, in the purchase of the same model with different configurations, in the case of adequate budget to choose a better light source. Secondly, it is practical. Taking independent brands as an example, many models are equipped with xenon light source. Generally speaking, xenon light source is better than halogen. So you can turn on the lights and get a feel for it. In my opinion, LED headlights are not important. It is better to have a daytime running light. Ordinary halogen headlights are enough for daily use at night.
