Both big brands have continuously launched a new car, and with the advancement of the car technology, the models on the market also have a variety of different headlights, including different light sources such as halogen lamps, HIDs, LEDs, may have many consumers for these light sources. The characteristics are not clear. This time introduces the advantages and disadvantages of these common headlights, but pay attention to these light sources and security are not directly related.
Traditional halogen lamp
Advantages: low cost, low color temperature
Disadvantages: short life, narrow irradiation range
Due to low cost, and will not make the opposite to the car, the halogen lamp often appears on the entry model, or some car factory uses the LED low beam with a halogen high beam, but because of the short life, and easy Fever, so it was eliminated.
HID Xenon lamp
Advantages: high brightness, high color temperature range
Disadvantages: short life, easy to scatter
This light source is currently, there is less seen on the market. Although the brightness is excellent in halogen lamps, there will be scattering conditions, which causes discomfort to the car driving, or even easily leads to an accident, so it is substituted by the LED, even compared to halogen The lamp is not common.
Advantages: low cost, low power consumption
Disadvantages: There will be limitations in the illumination angle
This is currently the most mainstream headlight source. It is also a long time than the above, and the shape can be more varied, but it is only necessary to pay special attention to the angle setting, otherwise it is easy to phenomenon. Even if many original headlights will have this situation.
Advantages: small size, brightness reaction
Disadvantages: high cost
As a higher headlight source, it is favored by many luxury brands, because the laser headlights inherit the advantages of the LED, even smaller, longer service life, and the brightness is quite amazing, just to create a laser headlight, must be complex The process, so the cost is high, and it has not yet been popular.
There is also a major focus, there is a confusion of universal consumers. It is to be aimed safely. In fact, the illumination distance is the key, while the halogen lamp does not lose HID and LED, Even some LED headlights do not take into account the illumination angle, the irradiation distance, and the reverse is not safe.
