Claim 0:
1. A multi-lighting projection warning device for vehicle turning, comprising:
a composite lamp combined with a range indicator light, a contour indicator light, and a text or pattern indicator light; and
a control unit connected to the composite lamp to enable functions of controlling rotation and start-stop lighting of the composite lamp;
wherein the composite lamp is arranged on one side of a vehicle and projects lighting to a visual blind spot when the vehicle is turning to form a warning area;
wherein the range indicator light is used to illuminate an entire range of the warning area;
wherein the contour indicator light is used to clearly mark a contour of the warning area;
wherein the text or pattern indicator light projects text or pattern on the warning area to enhance warning effect;
wherein the control unit is connected to an external audible alarm, an internal audible alarm, a first visual alarm and a second visual alarm;
wherein the control unit is further connected to a blind spot detector, a steering angle detector and a rotating speed detector, the blind spot detector is for detecting an object which is entering the warning area, the steering angle detector is for detecting a turning angle of a steering wheel of the vehicle, the rotating speed detector is for detecting a rotational speed of a wheel of the vehicle, and the steering angle detector and the rotating speed detector are configured to be activated after the object is detected by the blind spot detector;
wherein the control unit is configured to send out a first audible and visual warning message through the external audible alarm, the internal audible alarm and the first visual alarm when the object is detected by the blind spot detector;
wherein the control unit is further configured to determine whether, after the steering angle detector and the rotating speed detector are activated, the turning angle of the steering wheel of the vehicle is greater than a predetermined angle and the rotational speed of the wheel of the vehicle is higher than a predetermined speed;
wherein, when the turning angle of the steering wheel of the vehicle is greater than the predetermined angle and the rotational speed of the wheel of the vehicle is higher than the predetermined speed, the control unit sends out a second audible and visual warning message through the internal audible alarm and the second visual alarm.
