particularly, under the condition that a distance detection device is not arranged on a vehicle behind the vehicle, when the rear vehicle is close to the rear vehicle and has a collision risk with the vehicle, the projection graphic information can be displayed to the rear vehicle for watching through an information display lamp arranged at the rear part of the vehicle, the rear vehicle judges that the rear vehicle has a potential rear-end collision risk after observing the projection graphic information on the ground 20, measures such as braking and decelerating can be adopted to reduce the risk, necessary measures such as decelerating or adjusting the driving direction can be timely adopted according to the situation to avoid the rear-end collision accident, and the accident probability is directly reduced.
The invention takes the information display car light as a device for transmitting warning information to the outside, and visible patterns or characters are displayed on the ground 20 or the surfaces of other objects projected by light, thereby providing a way for sending warning to the surroundings, the car can simultaneously send out dangerous signals in time before a collision accident occurs, and the surrounding cars can adopt corresponding measures to further reduce the danger of the accident occurrence after knowing, and the probability of the accident occurrence is reduced; meanwhile, the transmission of distress information and the like among running vehicles can be realized by projecting the graphic information for identifying distress, so that the information interaction among the vehicles is facilitated, measures are taken together to reduce the probability of traffic accidents, and the driving safety is favorably improved.
When the vehicle runs to a road section with dense pedestrians, specific graphic information such as warning signals can be projected on the ground 20 at the periphery of the vehicle, surrounding pedestrians can notice related warning information, and therefore alertness can be improved, surrounding vehicles can be recognized in the first time, and the vehicles can avoid timely to reduce danger, so that probability of traffic accidents is reduced, lives and properties of the pedestrians can be guaranteed, and traffic efficiency is improved.
The embodiment further integrates the function of sending signals, increases the overall functionality and value, and is more favorable for meeting the requirements of consumers and market promotion.
Referring to fig. 1, in some embodiments, the projection direction of the projection module 200 is inclined downward. When the projection direction of the projection module 200 is set obliquely downward, the projection beam 13 passing out of the car light body 100 can directly strike the ground 20 to project visual projection graphic information, which is convenient for the outside to view.
