Which is brighter, xenon lamp or LED lamp

Of course, the xenon lamp is on!

The low-end of the xenon lamp can reach about 100 lumens.

LED flashlight 5W has a maximum of 50 lumens.

However, from the original consideration, LED lights are the first choice, and the power consumption is relatively low.

Xenon torches need to use lithium batteries, and the general xenon lamp lasts for about 60 minutes for two lithium batteries.

The cost of lithium battery is relatively high, and the cheapest section also needs 5 yuan. It's burning money every minute.

But the brightness can't be compared.

If you do need it, it is recommended to use a xenon lamp torch. In cost considerations, rechargeable lithium batteries can be used.

After I bought 3 high-brightness long-beam LEDs, I finally chose to buy xenon lamps. I really can't help it.

As far as brightness is concerned, LED and xenon are not comparable, I personally think that the penetration of xenon in rain and fog will be a little better, the advantage of LED is that it starts quickly, and xenon highlights take 1-2 seconds to reach the best state, but the service life of LED is generally shorter than xenon, LED will have a certain light decay in 1-2 years, and the brightness is not as bright as new.

If you pursue science and technology, the pursuit of new technology, it is okay to use LEDs, after all, many new cars now push LED headlights, but if you are a pragmatist, xenon is a better choice.

LED lights have an advantage in terms of luminous efficiency. However, the brightness of the LED lamp is sufficient, but the illumination distance is more limited than the xenon headlight, generally less than 10 meters. The xenon headlights are also bright, but slightly inferior to the LED headlights.

There are three types of car headlights commonly used in the market: halogen bulbs, xenon lamps, and LED headlights.

The halogen lamp is the bulb that is standard in the factory of the car, which can be said to be the first generation of car headlights; Xenon lamps are the second generation and LED headlights are the third generation.

The luminous principle of xenon lamp is: use a ballast to increase the voltage of the original vehicle from 12V to 23000V, and the high-voltage xenon gas produces arc light. Because the xenon lamp starts to increase the voltage, and the voltage needs to be increased a process, which also determines that the xenon lamp has a delay when it starts, that is, it must be slowly and slowly to be fully bright, with a delay of 5-15 seconds.

The luminous principle of LED lamps is: "light-emitting diode" emitting light, and "bright and power-saving" is the most significant feature of LED lights. The advantages of LED headlights are: fast starting, high brightness, good stability, and low energy consumption. The disadvantage is that it is currently more expensive.

But LED lights are a development trend in the future, so I personally think that LED lights are good.

Xenon headlight advantages:

1. The brightness is more than 300% higher than that of halogen lamps.

2. The tungsten-free structure also makes the life longer than that of halogen lamps.

3. It is more energy-saving and environmentally friendly than halogen lamps, and the power loss is saved by more than 40%.

4. If there is a fault in use, xenon, etc. will not be extinguished instantly, but will gradually dim until extinguished. This gives the driver on the road time to deal with headlight failures.

Xenon headlights disadvantages:

1. Poor light concentricity, and because it is too bright, it is easy to shake the driver of the opposite vehicle and cause accidents. However, the current xenon headlights are basically equipped with lenses, so this problem can be solved. But as far as I know, the Accord's xenon headlights are not equipped with lenses.

2. The penetration is too poor, in fog and ice and snow weather, the penetration of xenon headlights is very weak.

3. Delay effect. Because of the working principle of the xenon headlight, it takes 2-4s to light it. At high speeds, the horn is often useless, so you need to use the headlights to "shake" the vehicle in front, and it is completely impossible to rely on the xenon headlights.

Therefore, some manufacturers use xenon as an interface for low beam, while halogen is still used for high beam.

LED headlight advantages:

1. Long life, generally up to tens of thousands or even 100,000 hours. It has been argued that if LEDs are used for future car lighting, there will be no need to replace the lamps throughout the life of the car.

2. High efficiency and low energy consumption. The energy consumption of LED lamps is 1 20 times that of halogen lamps.

3. The light quality is high, it is an environmentally friendly product, basically no radiation, and the "green" light source.

4. The structure of LED is simple, the internal bracket structure, and the surrounding is sealed with transparent epoxy resin, which has good seismic performance.

5. There is no delay in lighting, and the light response speed is fast (nanosecond), which is suitable for objects with fast moving speed.

6. Suitable for low-voltage work, LED, which was first used in electronics, only needs a DC voltage of 12V to be lit, and there is no need to worry about the voltage of more than 20,000 xenon.

7. LED occupies a small size, and the designer can change the lamp mode at will, so that the car shape is diversified. Automobile manufacturers favor LEDs, which is completely determined by the advantages of LED itself.

LED headlights disadvantages:

1. The cost is high, the materials for a good LED headlamp should be sufficient, and the lamp beads are generally selected from imported wicks. The material of the lamp body, the fan, and the driver will all affect the heat dissipation effect.

2. In the past, it was difficult to popularize LED headlights, and the heat dissipation was not good, and the heat dissipation treatment was not good, and it was easy to fade. Affect the service life of the lights. Therefore, when choosing LED headlights, this part needs to be fully considered.

3. There is no industry standard, and the product quality is uneven;

4. The light type design is a little difficult; At present, most of the light on the market is dominated by two-sided light, and the light type design is not good, and the effect on the high beam is the same as that of xenon lamp.

Theoretically, LED lamps are brighter than xenon lamps; In fact, in most cases, xenon lamps are slightly brighter than LED lights. Under normal circumstances, the brightness of a xenon lamp can reach 3200 lumens; The brightness of the LED light can reach 3000 lumens. The reason for this is the heat dissipation problem between them.

The heat of the LED light should be dissipated in time, otherwise it will burn out instantly. Considering the cost, the power of LED lights will be comparatively smaller. If it is a high-power LED lamp, it is brighter than a xenon lamp, but there are few high-power LED lights.

LED lights are semiconductor cold light sources that emit light (the colder the cold light, the brighter it is). It has high luminous efficiency and long service life, but the power is difficult to amplify. Xenon lamp is a kind of high-pressure gas discharge lamp (hot light, the hotter the brighter), high light efficiency, basically no heat, high power, long service life.

Many times, LED lights look brighter than xenon headlights. This is because LED lights are brighter because of their high color temperature. But there is also a flaw, that is, poor penetration in rainy and foggy weather.

Therefore, in terms of specific use, the color temperature range of xenon headlights is wider and the effect is better. LED start: electrical energy is directly converted into light energy, which can be started instantaneously, without the need for pure delay, that is, it will be turned on when you click; b.

Temperature: The temperature of the LED headlight is about 90 degrees after 20 minutes of turning on (measured data) Brightness: The luminous efficiency of the LED headlight is 100-130lm W, the luminous efficiency is high, and the luminous brightness is about 4-6 times higher than the original halogen bulb.

Millions of car purchase subsidies.

Xenon lamps are brighter than LED lights.

In normal weather conditions, xenon headlights are brighter than LED headlights, and the illumination tone of xenon headlights is white, which improves the brightness of illumination, and can see the road signs and road potholes during driving more clearly, but the xenon headlights are not as strong as LED lights, and the light gathering is relatively low, but the brightness can be basically satisfied.

In harsh environments, the penetration of LED headlights is stronger, such as hail haze, heavy rain, sandstorm fog and other weather, so in this weather, the brightness of LED headlights is brighter than xenon headlights, which can maintain a high degree of recognition, but the heat dissipation ability of LED headlights is poor, and turning on LED headlights for a long time will cause the lights to be hot, and it is also more expensive.

On the whole, LED lights have more advantages. Here's why:

1. The energy consumption is only 1 20 of the halogen headlights.

2. Strong penetration, able to maintain high recognition in fog.

3. The service life is more than 100 times that of xenon headlights. Basically, your car is scrapped and the LED headlights are still working properly.

4. It can be turned on in an instant, and there is no need to wait for a while to turn on like a xenon headlight.

5. LED is a monomer structure, small in size, and can have more transformation forms in the design of automobile styling. The result of the xenon headlight is special, and the headlight will automatically go out when it encounters a fault, which is also a more troublesome problem.

What are LED Lights?

LED (Light Emitting Diode) is a solid-state semiconductor device that can convert electrical energy into visible light, which can directly convert electricity into light. The heart of the LED is a semiconductor wafer, one end of the wafer is attached to a stent cavity spike, one end is the negative ruler Yuanye, and the other end is connected to the positive electrode of the power supply, so that the whole wafer is encapsulated by epoxy resin.

A semiconductor wafer is made up of two parts, one is a p-type semiconductor, in which holes dominate, and the other end is an n-type semiconductor, which is mainly electrons here. But when these two semiconductors are connected, a p-n junction is formed between them.

When the current is applied to the wafer through the wire, the electrons will be pushed to the p-region, where the electrons will recombine with the holes, and then the energy will be emitted in the form of lingling photons, which is the principle of LED light emitting. The wavelength of light, which is the color of light, is determined by the material that forms the p-n junction.

Xenon lamps are brighter than LED lights.

In normal weather conditions, xenon headlights are brighter than LED headlights, and the illumination tone of xenon headlights is white, which improves the brightness of illumination, and can see the road signs and road potholes during driving more clearly, but the xenon headlights are not as strong as LED lights, and the light gathering is relatively low, but the brightness can be basically satisfied.

In harsh environments, the penetration of LED headlights is stronger, such as hail haze, heavy rain, sandstorm fog and other weather, so in this weather, the brightness of LED headlights is brighter than xenon headlights, which can maintain a high degree of recognition, but the heat dissipation ability of LED headlights is poor, and turning on LED headlights for a long time will cause the lights to be hot, and it is also more expensive.

Xenon lamps are better.

Xenon lamp is a heavy metal lamp, by filling the UV-resistant crystal quartz glass tube with a variety of chemical gases, such as xenon and other inert gases, and then through the supercharger to instantly increase the on-board 12 volt power supply to 23000 volts, at high voltage, xenon will be ionized and generate a light source between the two poles of the power supply.

Advantages:

1. High brightness: the brightness of xenon headlights is generally 3 times that of halogen lamps, which can reach 3000-4000 lumens.

2. Excellent color rendering: the color temperature is close to the color of sunlight, which is more comfortable for the human eye to accept.

3. Small light attenuation: annual light attenuation is less than 5%.

4. Low cost: The cost of Xingchun is lower than that of LED lights.

Disadvantages

1. The life expectancy of a group of xenon headlights is about 3,000 hours, while the life of LED lights is as high as 50,000 hours.

2. Fever: high calorific value, occasionally with high burn out of the lampshade.

3. Slow response: The response speed is slower than that of LED.

LED is an electroluminescent device that uses a solid-state semiconductor chip as a light-emitting material to directly emit light through the recombination of carriers to cause photon emission. LED headlights are lighting appliances made by using LED as a light source.

Advantages:

1. High brightness: higher brightness than halogen headlights, which is comparable to the brightness of xenon headlights.

2. Fast response: the headlights are lit up quickly, and they can be lit up in microseconds, which is safer.

3. More energy-saving: the luminous efficiency of LED is 80% to 90%, and the energy consumption is only 1 20 of halogen lamps, which can be driven by low-voltage direct current.

4. Long life: The LED components used in the car can basically reach the level of 50,000 hours, and the well-known automotive lighting manufacturers have been able to provide LED components with a life of 100,000 hours.

5. Small size: This is one of the most important advantages of LED headlights, all kinds of flowing turn signals, split headlights, and L-shaped headlights all make use of the small size of LED lights, which is convenient for layout and styling design.

Disadvantages

1. High cost: Compared with xenon headlights and halogen headlights, the cost is higher.

2. Heat dissipation: The heat dissipation of LED headlights is uneven, and it needs to be screened when purchasing.

Hernia lights, etc., are brighter than LED lights.

The differences between LED lights and hernia lights are:

1. Different ways of emitting light.

The xenon lamp emits light from a voltage of 12V or 24V through a ballast and instantaneously pressurizes it to reach a voltage of 20,000V. Breaks down the noble gas xenon and causes it to penetrate the emitted light. LED lamp emitting is through LED packaging technology, the chip is synthesized into patches, and the bright lamp beads are gathered in a small area to achieve luminescence.

2. The power consumption is different.

LED lights are more energy-efficient than hernia lights.

3. **Different.

Hernia lights are more expensive than LED lights.

LED lights are a bit brighter than xenon lamps

The distinctive feature of LED lamps is that they are composed of a large number, small volume and high brightness of the lamp particles, which are generally combined into a certain shape.

Advantages of LED lights:

1. Longer life. Normally, the shortest life can reach tens of thousands of hours and the longest can reach 100,000 hours.

2. The energy consumption is the lowest among all lamps, one-twentieth of that of halogen lamps. Therefore, LED lights are more environmentally friendly and energy-saving, and basically no radiation.

3. There is no delay in lighting, and it is suitable for combing objects with fast moving speed.

4. Low voltage operation. Only 12V DC voltage is required to light up.

5. Small size, can change the mode at will, so that the car shape is diversified.

6. The LED lamp adopts an internal bracket structure, which is sealed with transparent epoxy resin around it, with simple structure and good seismic performance.

Introduction of xenon lamps

Xenon wheel ruler lamp is also called HID gas discharge headlamp in the field of automobile lamps. It replaces the traditional tungsten filament with high-pressure xenon gas encapsulated in a quartz tube, providing higher color temperature and more concentrated illumination. Since a xenon lamp is a beam of arc light formed by activating xenon gas with a high-voltage current, it can continuously discharge between the two electrodes to emit light.

The power of the tungsten bulb of ordinary cars reaches 55 watts, while the xenon lamp only needs 35 watts, and the mountain tungsten lamp is reduced by nearly one and a half. Xenon lamps significantly reduce the burden on a vehicle's electrical system. Due to the low color temperature, the visual effect is yellowish, and the light penetration is stronger than that of the light with high color temperature, which can improve the driving safety at night and in foggy weather.
