How to choose the configuration combination of practical automobile headlamp?
2020-09-25 17:46:31

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.

Compared with xenon lamp, LED lamp brightness is enough, lighting distance is relatively limited, generally less than 10 meters.

It is worth mentioning that led lamp has higher luminous efficiency, very energy-saving and environmental protection, but its ability to withstand high temperature is slightly weak, and its concentrating effect is slightly worse than that of xenon headlamp.

LED light has many advantages, such as convenient brightness adjustment, long service life and low calorific value, but its price is too expensive, which is common in high-end models and top equipped models.

Statistics show that the global automotive lighting market in 2015 increased by 5.8% compared with 2014, and the total amount was close to 23 billion US dollars. By 2020, with the outbreak of new energy vehicles, the size of automobile lighting market will increase to 30 billion US dollars. In 2020, the global automotive LED lighting market is expected to exceed 10 billion US dollars.

Laser headlamp

The irradiation distance of laser headlamp is twice that of LED headlamp, and it has all the advantages of LED headlamp. The single light source is smaller, which is more conducive to modeling, and has longer service life, higher utility, longer lighting distance and higher intelligence. The only drawback is that the cost is too high and there is still a long way to go before popularization. At present, Audi and BMW have demonstrated their laser headlamps on some models.

LED headlamp is small in size and energy-saving, and xenon headlamp is formed as a whole and has a long irradiation distance. Laser headlamp is the future development direction of lamp. If the cost problem can be solved, it is expected to be popularized. At present, halogen headlamp is the most popular in the market, and xenon headlamp and LED headlamp are mostly used in medium and high-end vehicles.

The most reasonable or according to the needs of their own vehicles, choose different car headlamp configuration combination. When driving at night, the headlights need to be used alternately. Xenon lamp and LED lamp can be selected for low beam lamp to ensure long-time stable lighting at night and uniform light source. Driving communication will be displayed through high beam,

It is better to use halogen lamp or LED lamp, because xenon lamp brightness start time is slow. Finally, in terms of atmosphere, beauty and practicality, LED headlights are absolutely attractive.
