Hello everyone, I am Dazhou, and today I will talk to you about car headlights.
1. There are several types of car headlights
There are three main types that are widely used on the market, namely halogen lamps, xenon lamps, and LED lamps.
2. Next, lets talk about the characteristics of each type of headlight 1) Halogen lamp
1. Structure
Halogen is added to the tungsten filament bulb, and the color temperature is yellowish.
2. Features
Advantages: low cost, strong penetration in rainy and foggy weather. Disadvantages: high power consumption, high temperature, low brightness, short lifespan, and obvious brightness decay over time.
2) Xenon lamp
1. Structure
High pressure stimulates the hernia to glow.
2. Features
Advantages: high brightness, long irradiation distance.
Disadvantages: Slow lighting time, takes several seconds to reach maximum brightness.
The disadvantage of slow lighting is mainly reflected in the fact that when meeting another car, you want to use high beam to flash the other person to remind him that he wants to overtake. The effect of xenon flashing lights is particularly poor. It is not very bright, and the other party may not see you flashing him.
3) LED headlights
1. Structure
LED is a light-emitting diode, which is now widely used in residential lighting.
2. Features
Advantages: power saving, fast lighting speed, small size, and can be designed into various shapes; Disadvantages: heat generation, requiring a radiator.
