car headlights are standard parts, if not we driving at night lights will be how the scene it? After a while it changes for hundreds of years, has grown from the initial kerosene lamp, incandescent and now laser headlights, enough can be said to become a brilliant collection of magnificent history of the development.
for the car, the headlights like its eyes, especially at night with the lights is essential auto parts, led headlights is a common fixture in the market, and xenon headlights it is more of a fire lights, we often hear their names in the car modification, then what car xenon headlamps and LED headlights which is better? What are the advantages and disadvantages of it? gave you under the following .
First introduced to what xenon headlights and LED headlamps. It refers to a high-pressure xenon headlights gas discharge lamp. Xenon lamp is a heavy metal, by filling the inert gas such as xenon gas in the quartz glass tube quartz UV variety of chemical gases, then through the booster will increase the trigger voltage of 12 volt vehicle power instantly increased to 23,000 volts, to the car power protection effect, and the stable lamp emission, to improve the efficiency of use.
The LED light source is a light emitting diode headlights which we know, is an electronic light emitting device. Use of solid semiconductor chip as a light emitting material, the composite occurs through the carrier-induced emission of photons emitted directly, now led light car headlights most used are used.
For the xenon headlights, the advantage is obvious, since the xenon headlights do not need to tungsten light source, after full authentication practice xenon headlights long service life, brightness , does not produce unwanted glare, it has the following advantages:
1) good illumination, halogen lamp having more than twice the luminous efficacy;
2) the effect of strong security, to improve the brightness of the lights of the car is also effective to expand visual range in front of the car, thereby creating a safer driving conditions. To provide a road wider and brighter lighting effect, the driver noted that the vehicle has traveled to the roadside obstacle ahead and see;
3) is not extinguished instantaneously, a xenon lamp without the extinction of the event of failure, but by way of off progressively darker (or flash lighting), so that drivers can win the driving time in the night, to pull the emergency;
4) does not yieldHealth glare, xenon headlights will not produce excess glare (the case of a lens is mounted) will not interfere with the driver of an oncoming vehicle. But one thing we must pay special attention, xenon headlights must be used with the lens, concentrating mainly plays a role. However, if the lens is not used, xenon headlights scattered light emitted not only not achieve good lighting effects, will flash to a vehicle in the line of sight, what is absolutely dog in the manger element. In addition, xenon lights are bright enough, but the impact of weather problems it brings are still unable to solve, because the light from xenon lamps are generally white or even bluish, and in the rain and fog weather penetration is not obvious.
For LED lamps, because of its high luminous efficiency, a large brightness beam cohesive strength, which makes the irradiation distance LED headlight is remarkable . The main advantages are the following:
1) energy saving, since the light emitting diode by the electric energy directly converted into light energy, compared with ordinary automobile lamp power consumption is only about 1/10 of a conventional lamp, better fuel savings protection automotive circuits are not burned excessively high load current;
2) environmental Protection: no ultraviolet and infrared spectra, neither heat nor radiation, glare is small, and recyclable waste, no pollution, no mercury elements, safe touch, typical of the green illuminating light led sources;
3) long life: light body and no loose parts, there is no filament burn, thermal deposition, light fades and other shortcomings, the appropriate current and voltage a service life of up to 8-10 million hours of more than 10 times lifetime than conventional light sources;
4) high intensity, high temperature. Low temperature of the light emitting element peripheral material is not required high temperature performance, Common headlight opening 10 minutes easily surpass 200 degrees; Fast
5) response speed, led lighting only microsecond, with taillights and turn lights on It can quickly achieve a better warning effect lighting by front headlights, xenon lamps and halogen headlamps compared with a higher response speed, for better driving safety protection; good
6) stable , led strong seismic performance: the resin package, difficult to break, easy storage and transport. H
7) emitting purity, clear and bright color, shade without filtering, error is within 10 nanometers of light waves;
8) of low energy / power consumption can be fuel-efficient. But its high cooling requirements, if poor heat dissipation dramaticallyShortened life expectancy. And the higher initial purchase cost, maintenance is not very convenient.
The above is about the car xenon headlamps and LED headlights which is good, and both the advantages and disadvantages of introduction, two headlights in use have different effects can be selected, choose according to their needs when we in the choice the headlight is the best fit.
