Currently, there are three main types of truck headlights: halogen, xenon, and LED. So, what are the advantages of the headlight sources mainly used in these three types of trucks?

First of all, halogen headlights, also known as tungsten-halogen headlights, are widely used in the field of automotive lighting. Their brightness is relatively low, but they have the advantages of low cost, easy maintenance and replacement. Most of our domestic trucks are equipped with halogen headlights, and only a few high-end models will choose other light sources.

In fact, the halogen lamp is a variant of the incandescent lamp used in our home, and it also relies on the chemical reaction between the tungsten wire and iodine or bromine after sublimation. The cooled tungsten will re-solidify on the tungsten wire, so the tungsten wire will not decompose prematurely, which is why the life of the halogen lamp is longer than that of the incandescent lamp.

Xenon lamp, also known as xenon lamp, is a high-pressure gas discharge lamp, which belongs to heavy metal lamp. The xenon gas is installed in the crystal glass tube, and then the vehicle power supply is instantly increased by 23000 volts through the supercharger. Xenon will be ionized and a light source will be produced under the two-stage power supply. Optically, the luminous flux is more than twice that of halogen lamps.

Xenon lamps do not have tungsten filaments, but rely on electricity and gas. By ionizing the xenon, a light source is created between two electrodes and the gas is released. The light color produced by xenon gas is white super arc light, which is close to sunlight during the day. Moreover, the operating current of the xenon lamp is only 3.5 amps, which is very bright, but more expensive.

LED headlights, as the name suggests, are headlights that use LEDs as the light source. In fact, before LEDs were used as headlights, they have been used in daytime running lights, brake lights, reading lights and even turn signals for a long time, and the effect is very good. Now, after verification, LED light sources have been used in automotive headlights, and were first used in passenger cars.

The biggest advantage of LED is fast response, so as a brake light, it can increase the safety distance of 4-6 meters. In terms of anti-vibration, power saving and service life, leds are stronger than other lights. Moreover, the LED brightness is high and the color is relatively cool. Turning on the light at night will not attract flying insects. However, the cost of LED headlights is relatively high, and they are not widely used in trucks now.

As an important technology, car lights have a history almost synchronized with automobiles. Not only have various technological breakthroughs, but with the advancement of technology, the types of headlights are also increasing and becoming more intelligent. But generally speaking, cardholders can choose the type of headlights according to the road conditions they often drive, and the one that suits them is the best.

What are the main parts of the engine?

The main parts of the engine include: crank connecting rod mechanism: connecting rod, crankshaft, bearing bush, flywheel, piston, piston ring, piston pin, crankshaft oil seal.

Several classifications of filter element types

PP filter element is also called PP melt-blown filter element. The melt-blown filter element is made of polypropylene superfine fiber hot-melt entanglement. The fibers randomly form a three-dimensional microporous structure in space. The pore size is distributed in a gradient along the filtrate flow direction. , fine and fine filtration in one body, can intercept impurities of different particle sizes. The precision range of the filter element is 0.5-100μm, and its flux is more than 1.5 times that of the peak room filter element with the same precision. It can be equipped with different types of end cap joints to meet the needs of various engineering installations.

Engine Parts Classification

The engine is the heart of a car. I believe this understanding should apply to many friends. Although the momentum of new energy electric vehicles is in full swing, it is subject to some factors that have not broken through in key technologies and the infrastructure is not perfect. For traditional For fuel vehicles, the engine is indeed a key part, but for many friends who are not engaged in the automotive field, or even engaged in the automotive field but not in the engine field, the engine is still a relatively complicated thing.

How to maintain the shock absorber?

The shock absorber is a vulnerable part during the use of the car. The performance of the shock absorber will directly affect the driving stability of the car and the life of other parts. Therefore, we should keep the shock absorber in good working condition. The following methods can be used to check whether the shock absorber is working well.

How to choose truck accessories?

The outer packaging of authentic truck parts is of good quality. The writing on the packaging box is clear and the overprinting color is bright. Some manufacturers also put their own marks on the accessories. Some important components, such as generators, distributors, fuel injection pumps, etc., are also equipped with instruction manuals, certificates of conformity and inspector's stamps to guide users in correct use and maintenance. Be careful not to buy counterfeit and shoddy products.
