Inside and outside of the car lights, turn lights, brake lights, fog lights, headlamps, car instrument display and lighting etc.. The current market share of more than 10 billion yuan, 10 billion yuan market potential.
LED as a car headlights are mainly due to the low power consumption, long life and the characteristics of the corresponding speed. With the decrease of the cost performance ratio and the improvement of the luminous efficiency, the final LED will gradually realize the transfer from the interior of the car to the front of the rear to the front. With the huge capacity of the car, LED car market is facing tremendous development potential.
1) the advantages of LED automotive lamps
Tail light
The requirements of the tail light is not too high, but to be able to cause a certain attention, to do instructions and warnings.
Advantage
A, red and yellow LED technology are very mature.
B, LED volume is small, easy to use, to bring a lot of design space for the designer.
C, auto power supply for low voltage power supply, power supply circuit design is simple.
D, energy saving.
E, LED direction is good, in a certain range of high brightness, warning effect is obvious.
F, long service life.
Defect:
A, drive circuit is relatively complex (need PCB board), to the design of a certain form of trouble.
B, LED tail light repair.
C, the design of the spot has a certain difficulty (but not very difficult)
D, sealing requirements.
E, the price a little higher.
To sum up the technology of LED tail light is more mature, has been used for most of the car body manufacturers.
Interior lighting lamp
Car lamp is mainly used for car temporary lighting purposes, in the color index and color temperature requirements of small and even brightness requirements are not very high.
Advantage
A, a white light brightness and color rendering index, color temperature in the car completely suitable for short time use.
B, power design is simple.
C, LED volume is small, easy to use, to bring a lot of design space for the designer.
D, energy saving.
E, long service life.
Defect:
A, optical design has a little difficulty.
B, is not suitable for long time lighting, if long time lighting to consider a simple heat dissipation design.
C, poor maintenance.
D, point light source to make the appearance of the lamp and we used to light bulb has a certain gap, people's acceptance of the challenge.
E, the price a little higher.
To sum up, as the car lighting, LED has certain advantages than the traditional lighting.
The headlights
Headlights direction lamp, please refer to the tail; focal length lamp and focus lamp near the is of a strong light source type, mainly to ahead of the lighting.
Advantage
A, energy saving.
B, power supply circuit design is simple.
Defect:
A, heat problem is complicated.
B, brightness can not reach the requirements.
C, optical design complex.
D, the focal length and the focal length of the focal length lamp design contradiction.
E, sealing requirements strictly.
F, poormaintenance.
G, the price is high.
In summary, LED as a front headlight design there are a lot of technical problems, to have a certain technical strength to solve.
