If a person has a pair of beautiful big eyes, it will certainly improve a lot of points for his appearance. Similarly, for a car, a pair of bright headlights, like its eyes, depends on its appearance. Many vehicles also have different lamp light sources according to different configurations. Generally speaking, the common light sources are halogen, xenon and led. In that case, how are the three light sources different?
No.1 halogen light source
Halogen light source is one of the most common lamp light sources. Generally speaking, it is called halogen headlamp. Because the main component inside the lamp body is tungsten, it is also called tungsten halogen lamp or quartz lamp. It evolved from ordinary incandescent lamps.
Principle: the halogen lamp used in the vehicle headlights flushes halogen gas, such as iodine, bromine and other medium gases, into the interior of the lamp body. Because the tungsten wire will sublimate at high temperature, the halogen gas will have a certain chemical reaction with the sublimated tungsten at this time, and the tungsten wire that has become a gas will solidify on the original tungsten wire to continue to be used, This is similar to the balance of energy, so that the service life of the lamp can be extended for a certain period of time.
Features: simple structure, low manufacturing cost, acceptable low beam brightness, soft and uniform light, poor high beam brightness, good penetration effect in rainy and foggy weather due to yellow light. However, low overall brightness and short service life are the biggest disadvantages of halogen light source headlamps.
No.2 xenon light source
First, popularize a common sense. Many car fans will say "xenon" as "hernia". It must be remembered here that "xenon" is a kind of chemical gas with extremely inactive chemical properties, and "hernia" is a disease commonly known as "small intestine gas"! Remember! Remember! Remember!
Principle: the headlamp with xenon light source is called "hid gas discharge point headlamp" in the automotive field Its light-emitting principle is that the arc generated by the high-voltage arrester between the two electrodes emits light. A quartz tube filled with high-voltage xenon gas replaces the traditional tungsten wire, resulting in a higher color temperature and more concentrated light.
Features: the structure is more complex than halogen light source headlamps, and the manufacturing cost is higher. Generally, its brightness is more than three times that of ordinary halogen headlamp. Long service life.
No.3 LED light source
LED is the first to be known. Most of them are on mobile phones, computers and TV screens. When LED was just beginning to popularize, the electronic equipment carrying this technology was not cheap. LED light source is gradually popularized in office, home and other places where light is used due to its energy saving, long service life and soft and non dazzling light. Then I got on the bus.
Principle: LED is an abbreviation. Its full name is light emitting diode, which is translated as "light emitting diode". This is a solid-state semiconductor device. Its ability is to convert electrical energy directly into visible light. According to the different materials of inorganic semiconductors, the color of visible light emitted is also different.
Features: power saving, long life, high brightness. However, the manufacturing cost is the highest among the three lamp light sources. Therefore, the LED light source will not be selected as the headlamp light source on the general vehicle model. It is more used on daytime running lights. Maintenance costs are under control.
Searching for a vehicle light supplier, wholesaler, manufacturer from China, you can get high-quality products at a nice price.
