Auto lamp manufacturers to introduce the LED lamp market outlook
Light emitting diode)
Is a kind of low field in recent years, the rapid rise of type electric semiconductor light-emitting devices, is a kind of semiconductor to electric energy into visible light, it broke through the tungsten filament incandescent light shine with the principle of energy-saving lamps sanki toner glow, and adopts the electric light.
LED the spectra of almost all concentrated in the visible light spectrum, its luminous efficiency can reach 80%
Because of its long life, high light efficiency, low energy consumption, no radiation, no pollution, fast response characteristics, LED has been widely applied to the LED lamp lighting field.
Today, LED has been used in a lot of cars, the main brake lights, tail lights, turn signals, clearance lamp, back light, daytime running lights, fog lights, before the car headlights, reading lamp, can also be used for instrument and interior atmosphere decorative lighting.
In automotive lighting, predicts 2016, the LED will account for most of the automotive lighting (
Including reversing light and license plate lamp)
LED lights for all LED design has been more and more used in the factory car, in addition, the LED can also provide independent local lighting for car objects, such as dome light, reading lamp, grab handle, lock, switch, cup, belt buckles, mirror frame, seat atmosphere lamp, etc. , use is becoming more and more widely.
With the traditional vehicle lights,
Such as halogen lamp)
Compared, such as the LED energy saving, long life, maintenance-free, explosion-proof, easy to control and environmental protection advantages, combined with its own unique LED cold light feature, make the appearance of lamps and lanterns will not deformation, because long-term heat so as to improve the life of a complete set of lamps and lanterns.
LED is inherently has the advantages of small volume, is applied to the front headlights when the lamps and lanterns for the whole volume, more be narrowed further up valuable space engine space and other related equipment.
Existing halogen bulbs is designed by the discharge type bulb more, total length of about 300 mm in the headlight, and on the design of concept cars, LED lamps and lanterns is only 125 mm long.
The advantages of small volume, making the lamp design more flexible and, in turn, create different visual impressions for car body modelling, break through the traditional lamp design circle.
In addition, because the light faster than light bulbs, so quickly to the back of the vehicle brake message, help to improve the driving safety.
Therefore, LED to the automobile lighting system has brought a revolutionary development opportunity, will replace tungsten filament lamp, halogen lamp in an all-round way.
Currently widely used LED main color is white, blue, red and green, etc. , as the technology improved, brightness has gradually increased, color is also more and more rich, so the LED has a very good prospect in the application of auto lamp.
LED as a new type of light source to replace the traditional halogen light source on the technology is ripe.
From the current LED products market, the high cost of high brightness LED, car light source of the large number of demand for the LED brightness requirements, will undoubtedly raise the cost of car light source, however, with the development of LED product, industrial high brightness LED the increase of production capacity, price of LED products have a large range of fall, its good performance makes the LED light source will become the mainstream of car light source products.
