2., when warning front vehicle, laser module sends red laser, through shaping optical module device conversion laser shape and dispersion angle, projects bright red triangular form, have stronger warning function to front vehicle at automobile tail;
3., when this car travels, relative vehicle speed measurement module can measure the relative speed of a motor vehicle with rear car, and calculate rear car braking safe distance according to this car speed meter, and utilize laser module angle adjuster to adjust the distance of ground red laser bright line and this car according to this, remaining a safe distance behind the car in front to rear car provides alert;
4., when rear car too close, setting regions crossed by vehicle, then relative vehicle speed measurement module trigger alarm signals, and sound and light flash will warn this car and rear car driver.
Present invention improves conventional light source:
1, directivity is poor, irradiation area is relative with shape fixing;
2, penetrating capacity is poor, and the distance that traditional fog lamp can irradiate is very limited;
3, restricted lifetime, only has 300 to 500 hours;
4, function singleness, does not have the above defects such as auxiliary alarm function.
Because laser has stronger bite and visuality under misty rain weather, large-sized laser red triangular of the present invention possesses warning function more better than traditional fog lamp, and vehicle early warning distance significantly increases.Meanwhile, under fair weather, can form bright red bright line on car rear ground, when rear car distance surmounts red bright line, automobile itself can be sounded and light flash, to warn this car and rear car driver.
