Halogen headlamp: when it comes to the history of halogen headlamp applied to automobile, it can be traced back to the 1970s, which is also the most common light source type of automobile headlamp among various automobile manufacturers.

The headlamp regulator refers to the situation that the illumination direction of the headlamp deviates from the standard direction under the influence of the trunk load, long-time vibration, high and low road conditions.

The structure of automobile headlamp, the headlamp is an important lighting lamp, traffic regulations have requirements on the headlight's luminosity and illumination range, the lighting effect directly affects the traffic safety of you and others. There are two main types of headlamp: enclosed type and bulb replaceable type. Closed type refers to that the bulb,

There are many kinds of automobile headlight, among which halogen headlamp and LED headlamp are the most common. What is the difference between them?

Simple structure, low manufacturing cost, low market price, mature technology! Yellow color in rain, snow, fog and other extreme weather penetration effect is strong, so most halogen lamps are used in fog lamps. (the biggest advantage is the strong penetration)

LED lamp is the abbreviation of lighting emitting diode, commonly known as light emitting diode. Compared with xenon lamp and halogen lamp, LED has higher luminous efficiency and energy consumption is only 1 / 20 of halogen lamp. In addition, the cost of LED components has been greatly reduced year by year, and the cost and price are still falling by more than 20% per year.

The external application of automobile is also in continuous development. LED has been applied to brake lamp, tail lamp, turn signal lamp, reverse lamp, high brake lamp, etc., among which brake light, tail lamp and high brake light have large application scale. As a vehicle headlamp lighting, due to the need for high-power LED, it is restricted by technology and led cost performance, especially in the fields of optics, electronic control and thermal management. It will take three to five years to popularize, and the industry only starts to apply on some luxury high-end models. In addition to tail lights and high-level brake lights that are widely used at present, LED will also be widely used in turn signal and reverse lights in the future. In 2010, the market scale of domestic LED automobile lamps may exceed 1 billion yuan, and the annual output value of 3 billion yuan may be formed in five years. According to iSuppli's "2010 led special report" released in 2009, it is estimated that by 2013, about 95% of new cars in the world will use led in one or more tail lights

The headlamp is one of the most important parts of the car, but it is easy to ignore. As one of the most important parts of the car, it can be maintained in a good condition only by adding more maintenance at ordinary times. The following sorted out some knowledge of car headlight maintenance, I hope to help you.

The dark and turbid lampshade not only affects the beauty, shortens the visibility of light, but also seriously affects the driving. Dirty light will change the angle and range of light, not only affect the driver's own field of vision, but also affect the view of the opposite vehicle, thus causing tragedy in the meeting. Therefore, cleaning your lights regularly is not only for your own consideration, but also for others.

Luminous flux (brightness): the brightness of high-power LED car lights is generally between 1000-3000lm, with ultra-high brightness, which makes it safer for car owners to drive in rain, fog and night.

Check whether the size of the bulb package has the name of the manufacturer, address, telephone number, implementation standard, trademark number, packaging design, beautiful printing, and whether various brands are matched by well-known automobile factories.

Car lighting can be divided into two categories according to their uses: lighting and signal lights. The exterior lamp refers to the headlamp, the front fog lamp, the license plate lamp, and the interior lamp refers to the ceiling lamp, instrument lamp, etc. The signal lamp is also divided into external signal lamp and internal signal lamp. The external signal lamp refers to the direction indicator, brake lamp, tail lamp, width indicator lamp and reversing lamp. The internal signal lamp generally refers to the indicator light of instrument panel, mainly including steering, oil pressure, charging, braking, door closing prompt and other instrument indicators.

Car is an indispensable means of transportation for us to travel now. There are too many car lovers who care about their cars. As an important part of the car, the car lamp has a great influence on the car. The automobile bulb manufacturer will introduce the knowledge about the selection of the light color temperature. The color temperature is the most general indicator of the spectral quality of the light source. The color temperature is the absolute temperature K When a standard blackbody (such as platinum) is heated, the color changes gradually from red, orange, yellow, green, blue, indigo (blue violet) and purple when the temperature rises to a certain degree. Using the characteristics of this light color change, when the light color of the light source is the same as that of the black body, we call the temperature of the blackbody at that time as the color of the light source is the color temperature of the light source.

This should start from the shortcomings of xenon headlamp, which has a fatal disadvantage, namely astigmatism. Although the effect of "astigmatism" can only be seen by the driver of the opposite vehicle, it is very dangerous. Friends who are blinded by the headlights must have had a profound feeling. When the light of the opposite vehicle makes them unable to see the road ahead, it is easy to cause danger, so the astigmatism of xenon headlamp is a very dangerous problem. Therefore, you will find that models with xenon headlights are generally equipped with lenses. Only when used with lenses can the problem of astigmatism of xenon headlamps be weakened.

Automobile halogen bulb contains halogen gas such as iodine or bromine. At high temperature, sublimated tungsten wire reacts with halogen, and the light emitted is yellow, showing warm light color and relatively dark. If you want to improve the brightness of halogen headlamp, you can only solve the problem by replacing the brighter bulb. Relatively speaking, the brightest halogen lamp in the car is the bright halogen lamp, which can increase the light by 20%, which is better than ordinary halogen lamp and incandescent lamp.

With the development of automobile science and technology, the types of automobile headlights are constantly improved. Halogen headlamp, xenon headlamp, LED headlamp and laser headlamp have appeared successively, which have been applied in different vehicle models. Different types of headlamp sources have their own advantages and disadvantages. So, which of these kinds of headlights is the best light source?

Now automobile manufacturers will launch different configuration versions for the same model, so as to open the price to meet the different needs of consumers. However, some models only differ in a few unimportant configuration, but the price of the car is higher than 120000, so many friends will choose the suitable model and then refit it by themselves. Of course, the car less refers to legal modification, such as replacing the central control screen and installing reversing image. However, there is one configuration, we do not recommend upgrading and refitting, it is halogen headlamp.

The problem of automobile headlamp aging has been troubling car owners. Today, we will talk about the aging of automobile headlights. Why does the aging of automobile headlights turn yellow? In order to avoid the aging of automobile headlights, what problems should be paid attention to when using a car? How to repair automobile headlamp after aging?

In the case of fog in the headlights, we can not worry too much. After the lights are turned on for a period of time, the fog will be discharged from the lamp with the hot gas through the trachea, which basically will not damage the headlamp and the electrical circuit.
