Automotive knowledge: simple analysis of LED lights and their advantages and disadvantages

There are manycarLED car lights are installed (LED car lights refer to car lights that use light-emitting diodes as the light source), so how good is it? What are the advantages and disadvantages?

Advantages and disadvantages of LED car lights

The advantages of LED car lights are: long life, generally up to tens of thousands or even 100,000 hours. Some people think that if LEDs are used in car lighting in the future, there will be no need to replace lamps throughout the life of the car; high efficiency and low energy consumption. LED light source can be directly produced without color filterCar lightsThe required red, amber and other colors are lossless, and the power utilization rate is as high as 80% or more; the light quality is high, which is an environmentally friendly product and basically has no radiation, "green" light source; the LED has a simple structure, an internal support structure, and transparent surrounding Epoxy resin sealing, good seismic performance; no delay in lighting, fast response speed (nanosecond), suitable for fast moving objects; suitable for low voltage work, can be used in cars; LED takes up small volume , The designer can change the lamp mode at will to make the car diversified. Automobile manufacturers' favor of LEDs is entirely determined by the advantages of LEDs themselves.

The disadvantages of LED car lights are: high cost; poor heat dissipation, poor heat dissipation treatment is easy to light decay. Affect the service life of car lights; no industry standards have been issued, and product quality is uneven.

At present, the global automotive traditional light source lighting accounts for about 20% of the total output of the entire lighting source, so the automotive market is the most promising LED lighting segment.Experts believe that by 2013, all cars in the worldtaillightMore than 95% will use LED taillights. The entire market size of automotive LED taillights will reach an annual output value of 2.3 billion yuan. However, whether LED car lights can expand the market in the short term is not only determined by car manufacturers and car lamp manufacturers, but the most important thing is the progress of the entire LED technology itself. Only when the LED itself reaches a certain level in technology, can car lighting companies Only when automobile manufacturers produce car lights that are really suitable for mass production can they adopt car lights that meet their needs, and the LED car light market can really start. After reading the analysis of the editor, everyone knows more about LED car lights, right?
