Car headlights are generally spotlights or flashing lights

It should be a spotlight, not a flash.

Spotlight. The LED components on the car can basically reach the level of 50,000 hours, and the car lighting industry has been able to provide LED components with a life of 100,000 hours.

LED lighting only needs microseconds, used in taillights and turn signals can be quickly lit to achieve better warning effect, used in headlights, compared with xenon lamps and halogen headlights have a higher response speed, for driving safety has a better guarantee.

Is it better to spot or flood? It depends on the environment. In fact, you take a closer look at the assembly of the headlights of the car.

The low-beam reflector is wider, and the high-beam reflector is narrower, that is to say, when the automobile headlight manufacturer produces the headlight assembly, it is decided: the low-beam should be wider, the high-beam should be focused, and the farther should be illuminated.

In the words of your question, the high beam requires a spotlight, and the low beam requires a little more flood. For example, the "automotive LED headlight E2", which is very popular on the market now, is that the low beam paves the road wide, and the high beam focuses on the far. I am a car repairer, from time to time a car friend comes to me with this lamp to ask me to help install, I am more impressed by this lamp.

If you want to change the headlights, first make sure what type of headlights your car uses. Headlight models such as H1, H3, H4, H7, H8, H9, H, etc. On the manual or headlight assembly, the headlight model is engraved next to the headlight position, if you don't know, you can take a look.

Of course, you can also check it online.

The interface of the headlights of the car is unified, as long as the model is right, it can be installed.

If you don't pay attention to typing a lot of words, it is equivalent to practicing five-stroke typing or doing the popularization of headlight knowledge. Of course, I hope it can help you a little.

The 2mm ultra-thin design (the distance between the two lamps facing away from the emitting surface of the lamp bead) makes it very concentrating and the light pattern is the same as that of halogen lamps.

It's better to focus on the light, you can look farther. Floodlights always don't seem to be bright.

First, it is the same lamp, and now the cars are all high and low beam integrated headlights. 2. Working principle: There are two beams of light in the integrated lamp, which means that there are two beams of light in a single bulb.

Turn on the high beams at night when there are no street lights on the side of the road or the road is straight and far away, and the view is dark, and turn forward one block to get the high beams.

Its working principle is: the light emitted by a group of beams is reflected by the lampshade mirror and shoots straight forward, which is commonly known as "high beam"; The other group is the polarized beam, the light emitted to the visor blocks the upper part of the lampshade reflector, and the light reflected is diffused downward to the ground, which will not cause dazzle to the driver of the opposite car, this light source is commonly known as "low beam".

On the left side of the steering wheel there is a set of light combination switches, at night, the combination switch rotates forward one square is to turn on the dashboard light, and one grid is rotated to be low beam, (each brand of car combination switch is not the same, but it is roughly the same, and there are ** arrows are easy to operate). The low beam can be turned on at night when there are street lights on the road, and the low beam can also be turned on when there are pedestrians on the side of the road at night, and the low beam lights are turned on on narrow roads and narrow bridge curves.

If you turn on the high beams when you meet a car at night, you must turn off the high beams and wait for the car to finish before turning on the high beams, if you don't turn off the other party, you will be shaken by the high beams, affecting the other driver's line of sight, and accidents may occur, which is also the standard of civilized driving.

This is not certain, different models have different lighting configurations. Some models are equipped with high and low beam integrated headlights, then its high beam and low beam are the same bulb, which is longer than the ordinary bulb.

There are many different types of light bulbs in cars, some of which are one bulb and some are not, depending on the model.

For example, the old Great Wall C30 uses a headlight bulb of H4, which has two filaments in the same bulb.

Some of the car's light bulbs are a bulb and some are not. The difference is: some are one, and the H4 bulb is far and low beam together.

The H1 and H7 bulbs are separated. Car bulb is a bulb that ensures driving safety and illuminates the road when the car is driving at night, and the car bulb brings you safety and comfort while driving. Some models are equipped with high and low beam integrated headlights, its high beam and low beam are a bulb, there are two filaments in a bulb, one is the high beam filament, and the other is the low beam filament, which is longer than the ordinary bulb.

But now most of the models are independent of the high and low beams, so it is easy to distinguish. H4 type bulb, many low-end cars are in use, the headlights only have one set of bulbs (one on the left and one on the left), and then there are two groups of light groups in one bulb. Only one set of filaments is lit in the low beam state, and two sets of filaments are lit together in the high beam state.

This bulb has a dual-power design. Split bulbs, common lamp types with h1, h7, etc., are single lamps.

One car with two headlight clusters. Generally, the low beam is on the outside, the reflector is large, and the high beam is on the inside, and the reflector is small. In the low beam state, only the low beam group is turned on, and in the high beam state, the low beam and high beam group are turned on at the same time.

The design of the xenon headlights, which itself has only one lamp, also does not have dual power. Instead, a light visor was added. (Photo by photo:.)

This is uncertain. Different models have different lighting configurations. Some models are equipped with integrated high and low beam headlights, so its high and low beams are one bulb, which is longer than ordinary bulbs.

There are many different types of car bulbs, some are just bulbs and some are not, depending on the specific model.

For example, the old Great Wall C30 uses a headlight bulb of H4, which integrates far and low beams, and there are two filaments in the same bulb.

Some car bulbs are bulbs, and some are not. The difference: some are integrated, and the H4 bulb is a combination of high and low beams.

The H1 and H7 bulbs are separated. Car bulbs are light bulbs that ensure driving safety and illuminate the road when driving at night. Car bulbs bring you safety and comfort while driving.

Some models are equipped with integrated headlights. Its high and low beams are one bulb, but there are two filaments in one bulb, one for the high beam and one for the low beam. This type of bulb is longer than a regular bulb.

But most of the models are now independent of the distant smile buried light and low light, so it is easy to distinguish. Many low-end cars use H4 bulbs with only one set of bulbs (one on the left and one on the right) and then two sets of lights in one bulb. Only one set of filaments is lit in the low beam state, and two sets of filaments are lit together in the high beam state.

This bulb has a dual power supply design. Split bulbs, common lamp types are H1, H7, etc. , that is, a single light.

A car with two headlight clusters. Generally, the low beam is on the outside, the reflective bowl is large, and the high beam is on the inside, and the reflective bowl is small. In the low-beam state, only the low-beam group is on; In the high beam state, the low beam and high beam group are turned on at the same time.

Xenon headlights are designed with only one lamp and no dual power supply. But a light barrier was added.

Millions of car purchase subsidies.

Are car headlights the same as low beams No, headlamps include low beams. Because the headlamp is commonly known as the headlight, also known as the car LED daytime loss imitation lamp. Headlamps are the eyes of a car, which is not only related to the external image of a car owner, but also closely related to safe driving at night or in bad weather conditions.

Headlights generally refer to headlights, i.e., both high and low beams are headlights. Note: When the car is in use, the requirements for the headlights are:

Good lighting to avoid the glare of oncoming drivers. Therefore, the following points should be paid attention to when using headlights: (1) Keep the headlamp lens clean, especially when driving in rain and snow, dirt such as mud and dust will reduce the lighting performance of the headlamp by 50%.

Some models are equipped with headlights, wipers, and sprinklers. (2) When the two cars meet at night, when the two cars are 150m apart, the headlights and high beams should be turned off and switched to the low beams to ensure driving safety. (3) In order to ensure the performance of the headlamp, check and adjust the beam of the headlamp after replacing the headlamp or after every 10,000 kilometers.

4) Regularly check whether the bulb, line socket and ground wire are oxidized and loose to ensure that the connector has good contact performance and reliable grounding. If the contacts are loose, when the headlamp is turned on, the current shock will occur due to the on/off of the telemarketing lease, and the filament will be burned out. If the contacts are oxidized, the brightness of the bulb will decrease due to the increased pressure drop at the contacts.

Car headlights are not mega dipped low beams:

1. In order to ensure the safety of driving at night, the headlights should ensure that the front of the car clan is bright and uniform, so that the driver can identify any obstacles on the road 100 meters (or more) in front of the road;

2. The headlamp should have an anti-glare device to avoid passing at night, dazzling other drivers and accidents;

3. Automobile headlamps are generally composed of light sources (bulbs), reflectors, light distribution mirrors (astigmatism mirrors) and lamp housings.
