Nowadays, more and more cars use LED headlights, so what are the advantages and disadvantages of LED

<>Let's talk about the luminous principle of LED headlights first, after power-on, the LED chip directly emits light (excitation chemical energy directly emits), and the electrical energy is directly converted into photoelectric through the LED chip, skipping the step of converting into thermal energy, therefore, the LED light source is also called the cold light source! The invention of LED headlights is inspired by the glowworm, a glowworm shines on its own at night, without electricity or burning oil, do you say save electricity? Therefore, LED technology is called the third lighting revolution, and in the future, our household lamps will also popularize LED.

The advantages of LED headlights are: high brightness, the brightness is 4-6 times that of the original car halogen bulb; The temperature is very low, generally 50-70 degrees, because the temperature is low, the performance is very stable, there is almost no light decay, instant start-up, no delay. Moreover, the paving is very uniform, just like the "5D car LED bulb C6F" that often has riders who get me here to help install it during this time, the paving is very uniform, and it will not be like the original car halogen bulb or xenon lamp piece by piece, sitting in the cab, looking very comfortable, not easy to visual fatigue.

There are often car friends who bring lights to me and ask me to help install, 99% of people are equipped with LED headlights, the advantage is still obvious.

1) Energy saving, low cost, LED luminous efficiency of 80% 90% is halogen lamps can not be compared, less power consumption, (2) long life, automotive LED components can basically reach the level of 50,000 hours, and well-known brands of automotive lighting business has been able to reach 100,000 hours, converted to 11 years, in consideration of the use of lighting frequency is basically in the design life of the whole vehicle. Longer service life than xenon headlights. Nowadays, many cars give up xenon headlights with LED lights, such as Buick Envision, Yinglang, etc.

3) Good durability, simple structure of LED components, good impact resistance and shock resistance, not easy to break (4) LED components are small in size, compact and easy to arrange and shape (5) Fast response speed, LED lighting only takes microseconds, LED headlights have a higher response speed than xenon and halogen lamps, and have a better guarantee for driving safety (6) Low brightness attenuation, high LED brightness, and lower luminosity attenuation than halogen lamps.

LED lights are beautiful and have the excellent characteristics of light intensity sufficient. But once it rains, then the penetration of LED lights is not so strong, the halogen headlights of ordinary cars are not enough compared to the light intensity of LED lights, but its penetration in rainy days is excellent.

Advantages: Energy saving and environmental protection, can improve visibility when driving at night.

Disadvantages: It is too dazzling, and when keeping a distance from the car in front, the driver of the car in front will feel that the light is too dazzling, resulting in the driver's vision of the car in front of him being obstructed.

1.The advantage is that it saves power, and the light is very bright, which provides a good view. 2.The disadvantage is that it is more expensive to replace.

1. Energy saving: It is converted into light energy directly by the light-emitting diode, which is only equivalent to 1 10 of the traditional lamp compared with the ordinary automobile bulb, which can better save fuel consumption and protect the automobile circuit from being burned out by excessive load current.

2. Environmental protection: There is no ultraviolet and infrared rays in the spectrum, neither heat nor radiation, small glare, and the waste can be **, no pollution does not contain mercury, it can be safely touched, and it is a typical green lighting LED source.

3. Long life: there is no loose part in the lamp body, there is no filament light burning, thermal deposition, light decay and other shortcomings, under the appropriate current and voltage, the service life can reach 8-100,000 hours, more than 10 times longer than the traditional light source.

Fourth, high brightness, high temperature resistance. The temperature of the light-emitting element is low, and there is no requirement for the high temperature resistance of the surrounding materials, and the ordinary headlights can easily exceed 200 degrees for 10 minutes.

Fifth, small size. The designer can change the lamp mode at will, so that the car can be varied. Automobile manufacturers favor LEDs, which is completely determined by the advantages of LED itself. The shape is highly malleable, leaving a lot of room for design.

6. Good stability and strong LED seismic performance: resin encapsulation, not easy to break, easy to store and transport.

7. High luminous purity, clear and vivid colors, no need for lampshade filtering, and the light wave error is within 10 nanometers.

8. Fast response speed, no hot start time, can emit light within microseconds, and the traditional glass shell bulb has a second delay, which can prevent rear-end collision and ensure driving safety.

9. Energy saving: Low power consumption and fuel saving.

10. The color temperature is closer to daylight, which is better visually.

Disadvantages of LED Car Lights:

First, LED lights are more expensive than ordinary lights.

Second, the popularization of automobile headlights is difficult, the heat dissipation is not good, and the heat dissipation treatment is not good, which is easy to fade, which affects the service life of the lights. The biggest problem of high-power LED lights is heat dissipation, cheap ones are not heat-resistant, and heat-resistant ones are not cheap. Although LED lights have a long lifespan, there is another factor that affects the life of LED lights is the voltage instability.

Therefore, the requirements for the electronic control components of LED lamps are high, and a large part of the cost is added.

Third, there is no industry standard, the quality of the product is uneven, and the same product is produced by 1-2 times with different LEDs.

Fourth, the luminous light type of LED lamps is not quite the same as halogen, and it is not realistic to directly replace halogen bulbs, because most of the reflective bowls of cars are designed according to halogen bulbs. If you load the car, you have to reinstall the lamp bowl or lens, which adds a lot of cost.

LED Lamp Principle:

LED is a semiconductor that can convert electrical energy into visible light, which changes the principle of tungsten luminescence of incandescent lamps and the luminescence of three primary color powders of energy-saving lamps, and uses electric field to emit light. According to the analysis, the characteristics of LED are very obvious, long life, high light efficiency, no radiation and low power consumption. The spectrum of LEDs is almost entirely concentrated in the visible light band, and its luminous efficiency can reach 80 to 90%.

The advantages and disadvantages of LED lights are as follows:

1. Advantages: long life, generally up to tens of thousands or even 100,000 hours, high light quality, environmentally friendly products basically no radiation;

2. High efficiency and low energy consumption, LED light source can directly produce the color required by automobile lamps without color filtering, without loss, and the power utilization rate is as high as 80%;

3. The disadvantage is that the heat dissipation is not good, the heat dissipation treatment is not good, and it is easy to fade, and the ** grid causes ordinary cars to not be able to install LED lights.

At present, the application of LED headlights on automobiles is very common, so what are the advantages of automotive LED headlights?

1. It is very energy-saving and environmentally friendly. The LED on the car is not only energy-saving, high luminous efficiency, low energy consumption, but also environmentally friendly, in line with the current social requirements.

2. The size is small and does not take up space. A single LED lamp is small in size, and can be arranged and combined through different light groups to achieve different visual effects.

3. The quality is durable and lasts for a long time. Due to the relatively simple structure of LED, it has strong adaptability in anti-impact and anti-impact, and the quality is reliable, which improves its durability.

4. Long service life. The normal LED light can be used for about 50,000 hours, which is enough to support the long-term use of the car, reduce the frequency of replacement, and make it more comfortable and worry-free.

5. Fast response. The time to turn on the LED headlights is about a microsecond, which is very conducive to the use of taillights and turn signals, which can give a longer reaction time to the oncoming cars, thereby reducing the probability of traffic accidents.

The advantages and disadvantages of LED car headlights and the disadvantages of car LED lights were infiltrated, and the information on the Internet about the advantages and disadvantages of LED car headlights and the disadvantages of car LED lights was also collected. Let's share it with everyone.

Disadvantages: 2. Heat dissipation, which will greatly shorten the life.

3.The power saving rate of low-end LED lamps is still lower than that of energy-saving lamps (CCFLs).

4.The initial purchase cost is very high.

5.Due to the strong directivity of LED light source, the special optical characteristics of LED should be considered in the design of lamps.

6.Advantages: 7Energy saving and environmental protection: energy consumption of LED lights.

8.Low cost and long life: the LED lights of the well-known manufacturer can last for several hours, which means that the basic car is still on when it is started.

9.Brightness: Much brighter than halogen lamps, the warning light used as a brake light is stress-free. (Strong penetration).

10.Low voltage: LED, the first electronic component, only needs the DC voltage to light up, so you don't have to worry about the xenon voltage anymore.

11.Instant Illumination: You'll need a xenon lamp to "light it up later". It can be used at any time.

Small single rolls: This is a favorite of the designers. It can be put together into a variety of favorite shapes, and it is the favorite of lamp manufacturers!
