Description
Technical field
The present invention relates to technique of display field, more particularly, the present invention relates to a kind of LED exterior vehicle lights system.
Background technology
LED (Light Emitting Diode) is a kind of solid-state semiconductor devices, and it can be directly luminous energy electric energy conversion.The heart of LED is a semiconductor wafer, and one end of semiconductor wafer is attached on a support (as negative pole), and the other end of semiconductor wafer connects the positive pole of power supply, and whole wafer is got up by epoxy encapsulation.
Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, and inside it, occupy an leading position in hole, and the other end of semiconductor wafer is N-type semiconductor, at this side mainly electronics.Time these two kinds of quartz conductors couple together, between them, just form one " P-N junction ".
When electric current acts on this wafer by wire time, electronics will be pushed to P district, and in P district, electronics is with hole-recombination, then will send energy with the form of photon, the principle of LED luminescence that Here it is.And the wavelength of light determines the color of light, determine by forming P-N junction material.
Such as, LED has been used to make LED digital display board, and LED has been used to the LED-backlit module etc. making flat-panel monitor.Such as, LED digital display board can for showing score during sports tournament in real time.
In addition, LED is advantageously used in automotive lighting and instruction.LED car lamp refers to and adopts LED to be the car light of light source.The feature that brightness is high, color category enriches because LED has, low-power consumption, life-span are long, LED is widely used in automotive field.Common exterior vehicle lights has: head lamp, fog lamp, registration mark light, backing-up lamp, brake lamp, steering indicating light, Position indication lamp, flank indicator, parking lamp and Warning light and day portable lighter.The photochromic general employing of outside light fixture is white, orange-yellow and red; Perform the vehicle of special duty, as fire extinguishing tanker, police car, medical truck, breakdown van, then adopt and there is the preferential redness by power, yellow or B light flashes Warning light.
Exterior vehicle lights, no matter be outside instruction car light or exterior illumination car light, the traffic safety for vehicle is all very important.On the one hand, if outside instruction car light cisco unity malfunction, then the vehicle travelled in its vicinity cannot know next step traveling action of this vehicle, thus easily causes collision.On the other hand, if vehicle lighting car light when night running damages, then not only may look down upon the road oneself travelled, and opposite likely can not be caused to sail the attention of the vehicle come, thus cause potential safety hazard.
But in chaufeur general idea or when not having experience, the outside that chaufeur oneself sometimes cannot discover oneself indicates car light or exterior illumination car light to there occurs damage, brings very large potential safety hazard to thus the safety of chaufeur and vehicle.
Therefore, wish to provide a kind of effectively can detect vehicle outside instruction car light and the mode of operation of exterior illumination car light whether normal and by timely for testing result driver, thus prevent the solution of the potential safety hazard that chaufeur is not known and caused because outside instruction car light and/or exterior illumination car light are damaged.
Summary of the invention
