When driving, the lamp is not only a tool for lighting, but also a signal for communication on the road. Another important thing after the driver's license test is to fasten the seat belt. From the attention paid to the operation of the lamp, we can see that the lamp plays a role in driving safety at night.

If the driving light is too weak at night, it will not only affect our driving vision, but also accelerate visual fatigue. At the beginning, it is easy to make a wrong judgment, causing no small hidden danger to the driving safety. If the lights are too dark, they will get stuck during the annual inspection of the vehicle.

People who have no experience in lamp transformation often fall into misunderstanding in the transformation process. While determining their own needs, they should also pay attention to meeting the vehicle inspection specifications and not causing negative impact on other vehicles on the road.

Headlamp purchase elements

At present, there are three kinds of headlamp bulbs for household vehicles, halogen lamp, HID lamp and LED lamp, among which hid lamp is also called xenon lamp. If you want to know which lamp to choose, you should first know the differences between the three lamps, and these differences are also the key elements of choosing headlights!

How should the three lights be selected?

Next, let's take you through the following five aspects to understand what key elements should be paid attention to when upgrading your vehicle's headlights:

1. light intensity

Generally speaking, the illumination intensity of halogen lamp is about 1000 lumens, that of xenon lamp is about 4000 lumens, and that of LED lamp can reach more than 6000 lumens.

The lamp in my home used to be a halogen lamp, and the halogen lamp will gradually decay with the use of brightness, which is also the main reason why I want to change to a lamp with greater brightness.

In terms of brightness, LED lamps are preferred, followed by HID lamps and halogen lamps.

2. lamp power

The light-emitting of vehicle lamps is also a process of energy conversion, in which part of electricity is converted into light and part of electricity into heat.

At present, the mainstream halogen lamps generally consume about 55W of power, and the heating temperature is general.

The mainstream xenon lamp consumes about 35W of electricity, and the heating temperature can reach a high temperature of 300-400 ℃. This is because the xenon lamp is illuminated by a strong voltage, which produces relatively high heat and relatively low electro-optical conversion ratio.

Mainstream LED lamps generally consume about 25W of electricity, and the electro-optical conversion ratio is relatively the highest. The general temperature is about 60 ℃. Because of its low heating degree, it is also called a cold light source, which is also reflected in the LED table lamps at home.

Generally speaking, the higher the heating degree of the bulb is, the more unfavorable it is in terms of safety. The lower the temperature can also avoid the hidden dangers of vehicle safety.

3. light color temperature

Generally speaking, the color temperature of halogen lamp is about 3000K, that of xenon lamp is 3500k-8000k, and that of LED lamp is 4000k-6500k.

3000K light is yellow and warm, 5000K light is similar to natural light, and 6500k light is whiter than light.

Theoretically, the penetration is relatively good in rainy and foggy days, but due to the weak illumination intensity, the penetration effect of halogen lamp is worse than that of xenon lamp and LED lamp.

4. lighting effect

As the most traditional halogen lamp, the illumination is very uniform, but relatively speaking, the illumination width is also the lowest.

Xenon light photography for halogen lamps, the middle light is brighter, while the two side light photography is darker.

The illumination of LED lamp is relatively uniform, but its illumination capacity is often the widest among the three.

5. service life

Relatively speaking, the production cost of halogen lamp is the lowest, but the service life is also the lowest. Generally, the service life is about 500 hours. The process of weakening the service light of halogen headlamp is also the process of losing the life of halogen lamp.

The service life of xenon lamp is relatively long, which can generally reach about 3000 hours. However, compared with it, it needs to install ballast during upgrading, and the comprehensive cost is relatively increased.

The cost of one-time replacement of LED lights is high, but the service life is the longest among the three. It can even be said that sometimes when the car is scrapped, the lights have not been scrapped. Taken together, the cost sharing is the lowest.

Before, my home was a halogen lamp. After driving for many years, the brightness lost, and the light felt dark.

Based on the above points and my family's demand for improving the brightness of driving at night, LED headlights are preferred.

However, after deciding to purchase LED lights, you should also pay attention to some other purchase elements about LED lights.

Other elements needing attention in purchase

Lamp interface

Generally speaking, there are mainly H1, H3, H7, H11, HB3, hb4 and other models of small household car headlights, and the differences of these models are often related to their own car models.

The interface model of your car can be found in the vehicle maintenance manual, telephone the 4S store, and communicate with relevant customer service.

Heat dissipation mode

Although the LED lamp is called a cold light source, it also needs heat dissipation. The brightness of the LED lamp source is also affected by temperature. There are generally two heat dissipation methods for LED lamps, one is passive heat dissipation, and the other is active heat dissipation.

Passive heat dissipation is conducted by copper or aluminum lamp body with strong thermal conductivity and copper aluminum braided belt.

In addition to copper or aluminum lamp body heat dissipation, active heat dissipation also adds fans for heat dissipation, so the cooling effect is relatively better.

Lamp purchase and installation

Based on the above factors, the 6500k LED headlights are finally purchased for my car.
