Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle-mounted LED light bar, concretely relates to a vehicle-mounted LED light bar with emergency warning stroboscopic mode. BACKGROUND

[0002] In the process of driving, the safety warning device of the vehicle is like a loyal guard, which plays a vital role in ensuring driving safety. The traditional vehicle-mounted LED light bar mostly only has ordinary constant illumination function, like weak light on the calm lake surface, which barely meets the basic lighting needs in daily driving environment. However, once an emergency occurs, such as sudden braking, its shortcomings are exposed. At this time, they cannot timely and effectively send strong warning signals to the rear vehicles, and it is difficult to break the dullness in the normal state, so that the rear vehicle drivers cannot react, which easily causes rear-end traffic accidents and brings serious threat to the life and property safety of the drivers and passengers.

[0003] Some light bars claimed to have warning function, but their actual performance is not satisfactory. Their triggering mode is like a dull sense, which is not sensitive enough, and often responds slowly after an emergency occurs, missing the best warning opportunity. Moreover, their warning effect is not significant enough, and the signals they send are like a drop in the ocean in complex traffic environment, and are difficult to penetrate the surrounding noise and interference to attract the attention of other drivers. On busy urban roads, vehicles flow endlessly, and various lights and sounds are intertwined. These ineffective warning light bars are easily submerged in them and cannot play their due role.

[0004] In addition, the existing vehicle-mounted LED light bar also has many problems in installation and structural design. The installation process is complicated, like a high-difficulty engineering operation, which requires a lot of time and effort, and even professional personnel may be needed to operate, which brings great inconvenience to the car owner. At the same time, its function extension is poor, like a solid mold, which is difficult to flexibly adjust and upgrade according to the diversified use requirements of modern cars. With the continuous strengthening of the development trend of car intelligence and individualization, such backward design obviously cannot keep up with the pace of the times and cannot meet the pursuit of car owners for convenient installation and rich functions.
