The headlights on the market today are mainly divided into three types: halogen lamps, xenon lamps and LED headlights. What is the difference between these three types? As a Blowing Mould China Wholesaler, let's talk about it below. Generally, when the car is shipped from the factory, it is equipped with the original car halogen bulb, which is usually 55W.
The principle of a halogen lamp is to inject a halogen gas such as iodine or bromine into the bulb. At a high temperature, the sublimated tungsten wire chemically reacts with the halogen, and the cooled tungsten re-solidifies on the tungsten wire to form a balanced cycle, avoiding the tungsten wire. Premature rupture. Therefore halogen bulbs are longer than incandescent lamps.
The halogen lamp supply voltage is usually divided into AC 220V and DC 12V, 24V.
The halogen lamp is an improvement of the incandescent lamp, which maintains the advantages of the incandescent lamp: simple, low cost, easy adjustment and control of brightness, and good color rendering (Ra = 100). At the same time, halogen lamps overcome many of the disadvantages of incandescent lamps: short life and low luminous efficiency (generally only 6% to 10% can be converted to light energy, while the rest are lost in the form of heat).
Xenon headlights are currently the form of lights commonly used in mid- to high-end cars. Because of the high brightness of xenon lamps, they are usually equipped with lenses, and the light emitted is very focused, so they are loved by everyone, and the color is also compared. Unlike ordinary halogen lamps, the light is white.
Xenon lamps are irritated by high-voltage currents, so they have a longer life and better energy savings than halogen lamps. And the brightness is greatly improved by 300% compared to the halogen lamp. However, due to the higher technology, the cost of production is much more expensive than that of halogen lamps. But its brightness still makes many people like it.
Before the LED headlights did not come out, people used xenon lamps, which was a last resort. The temperature of the xenon lamp was very high, 300-400 degrees. The lamp holder was baked, and the lampshade was baked yellow, and it was very Power consumption. You should know that the xenon lamp is used to increase the original 12V voltage to 23000V through the ballast and then stimulate the arc to illuminate. How much energy is needed to raise the 12V to 23000V? Therefore, especially when the xenon lamp is started, the pressure on the battery is very large. This is also the reason why the xenon lamp has a delay and cannot be fully lit when it is powered on. Because the voltage is raised in a process, it can only be fully illuminated after being energized.
