What are the types of car lamps?

External lamps Combination lamps, cars assemble headlights, front turn signals and front indicator lights together, which is called combination headlights. The rear turn signal, brake light, rear position indicator light, rear fog light, and reversing light are assembled together, which is called combination rear light.

Fog lights: Fog lights are installed near or slightly below the headlights. When visibility is low, such as fog, snow, heavy rain or dust, it is used as a light to illuminate the road and signal oncoming cars. Most of the lamps are yellow, because the yellow light waves are long and have good fog permeability. The power of the bulb is generally 35W.

Mainly include: headlights (including high beam and low beam), front light, rear light, license plate light, instrument light, turn signal, brake light, hazard warning flash, reversing light, front fog light, etc. First of all, let's talk about the most common lighting headlights at the front of the car, which is the most commonly used light when driving.

There are four types of car headlights, namely halogen headlights, xenon headlights, LED headlights and laser headlights. Halogen headlights are currently the most commonly used type of automotive headlight source by major automobile manufacturers in all kinds of cars. Because the price of halogen lamps is relatively cheap, they are very suitable for some low-priced economic models.

Classified by light source · Halogen headlights Halogen headlights, also known as tungsten halide headlights, are a variant of incandescent lamps and are widely used in the field of automotive lighting.The principle is to use the current of the resistance to heat up, and when the temperature is high enough, it emits a wavelength of blackbody radiation in the visible light frequency band.

What are the types of headlights: The main purpose of headlights is to illuminate the roads and objects in front of the car to ensure driving safety. It can also use the alternating transformation of high beam and near beam as a night overtaking signal. Headlights are installed on both sides of the head of the car, and each car is equipped with 2 or 4.

What kind of bulb is better to use for car low beam lights?

1. First of all, let's talk about the advantages of xenon lamps: First, xenon lamps present blue and white light, which greatly improves the brightness of road signs and signs; secondly, the brightness intensity of xenon lamps is higher than the price, which effectively expandsThe visual range can ensure safe driving to the greatest extent. Of course, the most impossible thing not to mention is the power-saving xenon lamp.

2. The LED light is good. Halogen lamp is an upgraded version of incandescent lamp. The brightness is low, luminous yellow, and the electrical energy conversion efficiency is low, but the cost is low. Only the low-configuration model is about to be eliminated by the market. The principle of Led is more complex. Through the pn junction, the start-up is fast, the electrical energy conversion rate is higher, the service life exceeds the scrapping life of the vehicle, and the size is small.

3. In fact, there is no difference between good and bad. Early vehicles were all halogen headlights. With the slow upgrading of headlights, they are now basically LED headlights. The lights of halogen lamps are more concentrated, but compared with LED lamps, they are worse in terms of brightness. LED lights are stronger than halogen headlights in terms of brightness and aesthetics. Lamp.. Halogen lamps are easy to heat up.

4. From the perspective of the feeling of use, the hernia lamp is better, and the LED lamp has a better service life from the perspective of economy and environmental protection. It can be said that both have their own advantages and disadvantages.

5. LED light bulbs are better. This car can replace the led light source of the loom light separately in the later stage. As long as it is adjusted well, the lighting effect will be improved to a certain extent compared with the original car. The LED lamp is a cold light source, which will not damage the headlight assembly. The luminous point is fixed, which can solve the problem of astigmatism.

What are the models of car light bulbs

There are many models of car light bulbs, mainly divided into H and D, according to the lamp Distinguish between the number of feet and clamp teeth. Common models include HHHHH11 and so on. Different types of light bulbs are used in different positions.

HHH7 is three different models of light bulbs, all of which have halogen lamps and xenon lamps.

H4 is a double-filament tripod bulb. The near-light and high-beam are in one bulb. The standard is low-beam 55W and high-beam 60W; or near-beam 90W and high-beam 100W. Motorcycles are generally H4, 35W both far and near, or 35W far and 25W near.BAY15d, BA15d, BA15s, B13d and B10d are used for signal lights (brake steering).

Baojun 530 headlight bulb H7. There are many models of car light bulbs. Their main differences are the difference in bulb base, interface and external dimensions. Common models include HHHH900900D2S, D2C, etc.

Car lights are one of the important safety devices for vehicles. Different models of lights have different functions and uses. Generally speaking, car lights are divided into the following models: Headlights: Headlights are the main lighting equipment for vehicles, which can illuminate the road ahead from a long distance.

How many bulbs are there in the headlights of the car?

The headlights are installed on both sides of the front of the car, and each car has 2 or 4 headlights.The light bulb power of the high beam is 45~60W, and the low beam is 25~55W. Fog lights: Fog lights are installed near or slightly below the headlights.

Car headlights are generally divided into low beam and high beam. The single-light system uses one light bulb, and the double-light system uses two light bulbs.

There are two and four headlights in the car. It depends on what model of LED headlights are used. If it is a high and near beam integrated, it is a double light, and the headlight model is H4, that is to say, one lamp can achieve high and near beam, then, one on the left and one on the right, two on both sides.

Two. Car headlights are generally divided into low beam and high beam. The low beam bulb model is H7, and the high beam bulb model is H1. The function of high beam and low beam is to illuminate the road ahead of the vehicle.Road, the effective distance of lighting of the lom lamp should be 50 meters, and the effective distance of the lighting of the high beam lamp should be 150 meters.
