Description
Technical field
The present invention relates to car lighting technical field, particularly a kind of car lighting lamp.
Background technology
For automobile, lighting headlight is highly important part；At present, increasingly saying with automobile appearance fashion
Study carefully and develop, headlight is designed to the various moulding with aesthetic.Why automotive lighting can be in numerous LED application field
In show one's talent, be because its larger market scale and higher added value of product.With increasing for competing product, canal is sold
Road can also move towards diversification, whether orthodox car enterprise or new entrant, before more and more open market plane, constantly change
Enter itself, there is provided product and good service really up to the mark is only survival strategy, and LED illumination enterprise of China should hold automotive lighting development
Good opportunity, continuous lift technique competitiveness, one seat can be won in wide " blue sea " market of this piece.
2016, with the aggravation of competition competition, along with the price competition that the smoke of gunpowder rises from all around, LED illumination was into a piece of " red
Sea ", with automobile-used LED market scale sustainable growth, plus current ratio of average gross profit generally more than 20% so that LED manufacturers
Actively put into LED automobile illumination field.Counted according to related data, be with LED product permeability inside LED automobiles in 2016
85%, it is contemplated that rise to 90% to the year two thousand twenty.For LED tail-lights in permeability in 2016 close to 45%, the year two thousand twenty will be added to 67%.
LED daytimes portable lighter, fog lamp will rise to the 50% of the year two thousand twenty from 30% in 2016.LED headlight is by oozing from units in 2012
Saturating rate, 21% is risen to the year two thousand twenty is slow.As can be seen here, as the further breakthrough of technology, and people are got over to LED cognition degree
Come higher, LED will be increasing in the permeability of automotive lighting.In the near future, LED can with laser headlight,
Xenon headlight forms the gesture stood like the legs of a tripod, it could even be possible to turning into automotive lighting main flow.
At the beginning of 21 century, LED begins to be applied to small-power illumination, Japanese Toyota Company in automobile and is first applied to LED
The lower beam illumination of Lexus Chinese herbaceous peony illuminator.At present, only some a small number of high-grade car companies of foreign country are by great power LED headlamp commodity
Change, less enterprise carries out the research and development and production of LED headlamps at present in China.Its maximum problem is LED heat dissipation problem.
Current most of heat sink conceptions are more complicated, occupy substantial amounts of lamp body structure.LED light source has that low in energy consumption, controllability is strong, the longevity
The features such as long is ordered, is widely used in modern lighting field, it has also become the direction of countries in the world illuminating product development.With partly leading
The field such as the continuous development of body industry and the improvement of technology, LED forward directions high-power illumination such as automotive lighting strides forward.LED exists
In automotive illumination applications in addition to as interior trim ornament lamp, most important application is that to include steering indicating light, in-car reading lamp, automobile big
Automobile lamp including lamp and the 3rd brake lamp etc..
Most of white LED lamps are obtained using blue-light LED chip irradiation yellow fluorescent powder in the market, LED chip
With being produced in a manner of fluorescent powder packaging is together with.When being operated by the use of LED as light emitting source, LED chip meeting
Substantial amounts of heat is produced, if caused heat can not disperse well, epoxy resin and fluorescent material coking can be made, cause LED
Lamp brightness reduces, and shortens the service life of LED.The power of LED chip is bigger, and caused heat is also more, it is therefore desirable to
Large volume of heat abstractor carries out radiating treatment, and the volume of heat abstractor is more big also results in the final volume of LED light source
Become big, be very restricted application of the LED illumination in many fields.In addition, even if there is heat abstractor, to the shadow of fluorescent material
Sound is still larger, and the service life of LED is not also obviously improved.Therefore, in LED the defects of heat dispersion, LED light is caused
The development in source is very restricted.
