At present, the LED market has penetrated into general lighting, landscape lighting, backlighting, and even new areas such as security equipment, automobiles, and communications.
From the field of automotive lighting, the development of automotive industry technology is changing with each passing day, and its development direction is becoming more and more intelligent and green.
It can be said that automotive lighting is transforming from the traditional lighting field to the emerging LED field.
Osram, Philips and other lighting giants have released LED lighting products for automobiles, which are used in the application of taillights, directional lights and brake lights. The share of LED lighting for automobiles is also increasing year by year.
According to the statistics of the National Highway Traffic Safety Bureau, although the night driving time only accounts for 1/4 of the total driving time, the proportion of deaths caused by traffic accidents accounts for 1/2. In addition, the statistics of world automobile safety accidents It shows that the number of car traffic accidents in the world is more than 10 million per year, including about 500,000 deaths. The traffic accidents that occur at night are three times that of the daytime, and the accident rate when lighting conditions are poor is three times that of good lighting.
Because the LED lights are fast, they can reflect the condition of the car and the road in real time, leaving the driver with a longer judgment time. According to the measured speed of 100 kilometers, the rear car can shorten the braking distance by 7.5 meters. Effective prevention of rear-end collisions and reduction of vehicle safety accidents are of positive significance for improving the active safety of automobiles. Industry experts said. In addition, LEDs are controllable, such as light type, illumination range, and brightness, which can be linearly adjusted, while conventional xenon lamps are not.
In recent years, LED technology has been continuously developed, technical shortcomings have been overcome, and LED lights have become more and more intelligent. For example, some models of LED headlights are equipped with a contra-directional vehicle detection radar and a control computer. Even if the driver turns on the high beam, the opposite vehicle will automatically light down the light and even reduce the brightness.
Energy saving and environmental protection is another significant advantage of LED lights. According to the Ministry of Industry and Information Technology, as of the end of 2015, automotive lighting needs to meet the carbon dioxide emission reduction targets. Since the LED lamp is a cold light source, it has the advantages of low power consumption and long life, and consumes only 1/10 of the power of the conventional lamp, which can save fuel consumption. It is reported that if the daily energy-saving lamps are used, the energy-saving lamps can save energy by 4/5 compared with incandescent lamps, and the LEDs can save energy by 1/4. In the cars, the same daytime running lights, the energy consumption of LED components Only 1/20 of the halogen lamp.
In addition, LED lights have the advantages of high brightness, high temperature resistance, small size, high stability, no radiation, etc., and are recognized as green lighting. In the future, LEDs will be favored by more auto manufacturers, and will be more widely used in automotive applications. The LED automotive lighting market is promising.
LED lighting only needs microsecond level, it can be quickly illuminated on taillights and turn signals to achieve better warning effect. It is used on headlights and has higher response speed than xenon lamps and halogen headlights. Driving safety has a better guarantee.
LED small and rich changes fully meet the evolutionary needs of automotive manufacturers in design, breaking the shackles of the past lighting system for styling innovation, let us have more creative automotive products.
LEDs are especially suitable for automotive exterior lighting. They have an extremely long service life and are not sensitive to vibration and environmental influences. And the efficiency is extremely high. The output of the LED is extremely high and the energy consumption is very low. The efficient futuristic technology of LED with both fashion and reliability has made the car a focus of attention.
