For example, traffic police who install width lights, chassis lights, interior atmosphere lights, ranger lights, reading lights and teary-eyed lights will not check unless you change cars too much, which will affect the traffic police's command of traffic at night.

1, Introduction:

LED lamp refers to the light source inside and outside the car using LED technology for external and internal lighting. External lighting equipment involves thermal limit and EMC problems, and there are many complicated standards for unloading load test. LED car lights can be widely used to create an indoor environment, with a service life of 50,000 hours. The LED structure is firm, which is not easily affected by vibration, and the brightness of light output will not decrease obviously during use. LED lamps are suitable for various lighting applications of automotive electronics, including headlights (high beam and low beam), fog lamps, tail lamps, brake lamps, turn signals, daytime running lamps, pedal lamps, instrument lamps, license plates, door lamps, interior lamps, width lamps, navigation, entertainment systems, backlights and indicator lamps.

2. Advantages

1. Energy-saving: Light-emitting diodes directly convert electric energy into light energy, which consumes only110 less than ordinary automobile bulbs, thus saving fuel consumption and protecting automobile circuits from being burnt out by excessive load current.

Second, environmental protection: there are no ultraviolet rays and infrared rays in the spectrum, with low calorific value and small radiation and glare. Moreover, the waste can be recycled, pollution-free and mercury-free, and can be safely contacted. It is a typical green lighting led light source.

3. Long service life: the lamp body has no loose parts, and there are no shortcomings such as easy burning, thermal deposition and light decay of the filament. Under proper current and voltage, the service life can reach 8-65438+ 10,000 hours, which is more than 10 times longer than the traditional light source. (with the characteristics of one-time replacement and life-long use)

Fourth, high brightness and high temperature resistance. (Electric energy is directly converted into light energy, with low calorific value, which can be completely touched by hand, so it is safe and secure. )

Fifth, the volume is small. Designers can change the lamp mode at will, which makes the car shape diversified. Automobile manufacturers favor LED, which is completely determined by the advantages of LED itself.

Sixth, the stability is good, and the led has strong seismic performance: it is encapsulated by resin, which is not easy to be broken and easy to store and transport.

Seven, the luminous purity is high, the color is clear and bright, there is no need for lampshade filtering, and the light wave error is within 10 nm.

Eight, the reaction speed is fast, and it can emit light in microseconds without hot start time, while the traditional glass bulb has a delay of 0.3 seconds, which can prevent rear-end collision and ensure driving safety.
