Which is better to change the car to xenon or led

with the rapid development of economy and technology, more and more people buy bicycles. However, in the process of buying a car, many people only pay attention to the brand and performance of the car, but ignore many details. For example, which kind of car lamp should I choose? Is it good to choose LED headlights? Or xenon headlights? Let's learn about LED headlights and xenon headlights first

xenon headlamp refers to high-pressure gas discharge lamp. Xenon lamp is a heavy metal lamp. It fills a variety of chemical gases, such as xenon, in the anti ultraviolet crystal quartz glass tube, and then increases the triggered voltage through the supercharger to instantly increase the on-board 12 volt power supply to 23000 volts, so as to protect the automotive power supply, stabilize the lighting of the lamp and improve the efficiency of use. This is xenon headlamp

1. Good lighting

it has more than twice the lighting effect of halogen bulbs

2. Strong safety effect

the improvement of vehicle lamp brightness also effectively expands the visual range in front of the vehicle, thus creating safer driving conditions. It can provide a wider and brighter lighting effect for the road, so that the driver can notice that the vehicle has driven to the roadside and see the obstacles ahead

3. It will not go out instantly

once the xenon lamp breaks down, it will not go out instantly, but will go out gradually (or turn on quickly), so that the driver can win time during driving at night and pull over in an emergency

its trade association is trying to gain recognition in the industry. 4. There will be no glare.

xenon headlights will not produce excessive glare (when the lens is installed) and will not interfere with oncoming drivers

disadvantages

1. Poor focusing performance

low penetration rate in rainy, snowy and foggy days

2. Automatic flameout

electromagnetic interference is generated due to excessive starting current. The ballast can be installed away from the engine or replaced with a low current starting ballast

led is a light-emitting diode, an electronic light-emitting device. Solid semiconductor chips are used as light-emitting materials to emit light directly through photon emission caused by carrier recombination. Nowadays, most automotive headlamps use LED light sources

1. Energy saving and low cost

led has high luminous efficiency, which is nearly twice that of fluorescent lamp. For the same daytime running lamp, the energy consumption of LED components is only 1/20 of that of halogen lamps. The cost of LED components has also been significantly reduced year by year, and the current cost and price are still falling by more than 20% per year

2. Good durability

led components have simple structure, excellent impact resistance and seismic resistance, are not easy to break, and can well adapt to various environments

it can be equipped with bending centers with different diameters. 3. The components are small, compact and convenient for layout and modeling design.

this is a huge advantage of LED. This advantage fully caters to the evolutionary needs of automobile manufacturers in design, breaks the shackles of lighting system on modeling innovation in the past, and enables us to have more creative automobile products

4. Extremely long service life

at present, the LED components used in automobiles can basically reach the level of 500 hours in such a period of development, while the well-known automotive lighting suppliers have been able to provide LED components with a service life of 100000 hours, which is equivalent to 11 years. Considering the service frequency of the light, basically in the design life of the whole vehicle, the LED components do not need to be replaced

5. Fast response speed

led only needs microseconds to light up. When used in tail lamps and steering lamps, it can light up quickly to achieve better warning effect. When used in headlights, it has higher response speed than xenon lamps and halogen headlights, and better guarantee driving safety

6. Good adaptability

it can be driven by low-voltage DC, with small load, weak interference, low requirements for the use environment and good adaptability

disadvantages

1. Heat dissipation problems

poor heat dissipation will greatly shorten the service life

2, strong directivity

due to the strong directivity of LED light source, the design of lamps needs to consider the special optical characteristics of LED

to sum up the advantages and disadvantages of xenon headlights and LED headlights, considering the price factor and scope of application, only half a headlamp with xenon weight of glass can meet most of the needs. However, from the perspective of scientific and technological progress, LED lamps are better than xenon lamps, but in fact, there is no unique answer, because everyone looks at things differently
