What are the advantages and disadvantages of car led lights
Advantages of car-led lights:
1.long life, generally can reach tens of thousands or even hundreds of thousands of hours. Some people think that if the future car lights use LED, the entire life of the car will not replace the lamps.
2.high efficiency and low energy consumption. LED light source does not need color filter can directly produce red, amber and other colors, no loss, power utilization rate of more than 80%.
Disadvantages of car led headlights:
The cost is high. Take LED reverse lights as an example, an LED reverse light is nearly 30 yuan, while the price of a bulb is only 3 yuan, many of which are the cost of LED lights. High prices lead to ordinary cars can not afford to install LED car lights, the market can not be promoted.LED car headlights are difficult to popularize, heat dissipation is not good, heat dissipation treatment is not good, easy to light decline. Affect the service life of the headlights.
LED can directly convert electricity into visible light, with a very high conversion efficiency. Many luxury brands use full LED as the light source of headlights, and after the promotion of the market, more brands also put LED to the small car market. Under the future market trend of energy conservation and environmental protection, LED light source is likely to become the mainstream.LED light source energy consumption is only 1 / 20 of the halogen lamp, life can reach more than 100000 hours, basically the car to scrap, lights can normal use, compared to xenon headlight volume is smaller, and can instantly light, for the safety of driving is very guaranteed, but the LED light source for cooling ventilation requirements is very high.
1.Energy saving: it is directly converted from light-emitting diode from electric energy to light energy, and the power consumption is only 1 / 10 of the traditional lamp, 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 in the spectrum, small heat, no radiation, small glare, and waste recycling, no pollution without mercury elements, can be safely touched, belongs to a typical green lighting led source.
3.Long life: there is no loose part of the lamp body, there is no filament light easy to burn, heat deposition, light decay and other shortcomings, under the appropriate current and voltage, the service life can reach 800,000-100,000 hours, more than 10 times longer than the traditional light source life.(With one replacement, lifelong use)
4.High brightness, high temperature resistance.(Electric energy is directly converted into light energy, small heat, fully touched by hand, safe and assured)
5.small volume. The meter can change the lamp mode at will, make the car shape diversification. Auto manufacturers favor LED, which is completely determined by the advantages of LED itself.
Six, good stability, strong led seismic performance: resin packaging, not easy to break, easy to store and transport.Seven, luminous purity is high, clear and bright color, no need for lampshade filter, light wave error within 10 nanometers.Eight, the reaction speed is fast, no hot start time, micro seconds can emit light, the traditional glass shell bulb has 0.3 seconds delay, can prevent rear-end, to ensure the driving safety.
