With the continuous development of science and technology, now the functions on the car are more and more abundant, before the car was only equipped with halogen headlights, now many cars of about 100,000 yuan have been replaced with LED headlights. Halogen headlights are not far enough to illuminate the range, the light source brightness is dark, according to the reason, should be eliminated, why are there halogen lamps now?
First of all, let's understand the gap between halogen lamps and LEDs and car lights. The biggest difference between the two is the lighting principle is different, halogen lamps are added to the traditional incandescent bulb or halogen gas such as bromine, LED bulbs are light emitting diodes that will excite radiation after power, and energy will produce light.
The lighting effect of halogen lamps and LED lamps is quite different, because halogen headlights are equivalent to enhanced versions of incandescent lamps, so the lighting of halogen lamps is very close and the light efficiency is relatively low. The lighting intensity of LED headlights is greater and the power is greater, and the lighting effect of LED lamps is 2 to 7 times that of halogen headlights.
The third difference between halogen headlights and LED headlights is the difference in service life. Improving the luminous efficiency of halogen lamps requires increased heat, so the service life of halogen lamps is only about 500 hours, and the enhanced version of halogen headlights can illuminate for 2000 hours. The performance of LED headlights is not the same, as long as the light-emitting diode is not bad, this lamp can always be on.
At present, the led headlights on the market have reached 50,000 hours of lighting time, and the service life is 15 to 25 times that of halogen headlights. LED headlights are the product of science and technology, as long as the car companies do a good job of cooling and heat dissipation, such lights are difficult to damage.
Why not eliminate halogen headlights?
First, the price is cheap and the manufacturing cost is low.
Car companies need to control the cost when building cars, LED headlights although the lighting intensity is large, the service life is long, but the price of such lamps is very expensive. Medium to high-priced vehicles can be equipped with LED headlights as standard, but cheap cars can only use halogen headlights in order to control manufacturing costs.
Second, the effect is better in bad weather.
The lighting effect of LED headlights is farther away in the usual use process, but in extreme and bad weather conditions, the penetration and lighting effect of LED headlights may not be as good as halogen headlights. Some car owners will privately modify xenon headlights to make the bulbs shine through high pressure, and the advantages of such lamps are long life and higher brightness.
The types of xenon headlights are very complete, and some low-end cars use halogen headlights, but the owner can modify the lights by themselves. At their own expense, owners have replaced halogen lamps with LED headlights or xenon headlights, and some cars currently use laser headlights to illuminate the intensity farther.
Editor's Comments:
The owner can modify the lights, but the modified lights must be legal and compliant, and the owner needs to file with the vehicle management office before modifying the lights. Some car owners are extremely poor in quality, and deliberately do not add lenses when modifying the lights, although such lights are farther and brighter, but they will affect the normal driving of other owners.
Some car owners did not go to the vehicle management office for the record before modifying the lights, and the data of the vehicle was destroyed during the process of transforming the lights, and the lights were likely to be suddenly damaged during the driving process of the vehicle. The owner of the car modified the headlights without permission, and destroying the original structure of the lamps will also affect the annual inspection pass rate. I hope that everyone can modify the headlights under the scope of legal compliance, avoid safety hazards, and successfully pass the annual inspection.
