detailed description

Please refer to FIG. 1 to FIG. 3 . FIG. 1 is a schematic view of a brake warning light 100 installed on a car 200 according to an embodiment of the present invention. The brake warning light 100 can be designed in different sizes for installation in different types of automobiles, such as cars, commercial vehicles, trucks and so on. In this embodiment, the automobile 200 is a sedan. The brake warning light 100 can be installed at the rear of the car 200, so that when the brake warning light 100 is activated, the attention of the cars behind can be drawn.

The brake warning light 100 is arranged at the rear position which can attract the attention of the cars behind to the greatest extent. In this embodiment, the brake warning light 100 is installed at the center of the rear of the automobile 200 , and is located between the two tail lights of the automobile 200 . Specifically, the brake warning light 100 is installed in the rear center of the trunk lid of the car 200, so as to directly face the cars behind and be more easily noticed by the drivers of the cars behind.

There are many ways to install the brake warning light 100 on the automobile 200. The brake warning light 100 can be installed and fixed on the automobile 200 directly through screws, glue, etc., and the installation structure can also be preset on the automobile 200 ( not shown), and then detachably connect the brake warning light 100 to the installation structure.

The light source of the brake warning light 100 is an LED light source. In this embodiment, the brake warning light 100 includes a single-sided LED light board 10 . An LED module 20 is installed on one side of the LED lamp board 10 . In this embodiment, several LED chips 22 are arranged in an array in the LED module 20 . These LED chips 22 can be arranged in a certain pattern, such as circles, squares, etc., or designed to be arranged in specific letters, numbers or characters.

The LED lamp board 10 is further equipped with a distance sensor 30 , and the distance sensor 30 is located on the same side of the LED lamp board 10 as the LED module 20 . The distance sensor 30 is used to detect the distance between the vehicle 200 and the vehicle 300 behind. The distance sensor 30 can be an infrared distance sensor, a laser distance sensor or the like. The distance sensor 30 is electrically connected to the LED module 20 . A predetermined value is set in the distance sensor 30, and when the distance between the automobile 300 and the automobile 200 at the back reaches the predetermined value, the distance sensor 30 sends a signal to the distance sensor 30 through a signal transmission unit (not shown). The LED module 20 sends a start signal, and the LED chips 22 in the LED module 20 are activated accordingly.

The signal transmission unit can be integrated into the brake warning light 100 . The signal transmission unit may include a signal transmitter directly electrically connected to the distance sensor 30 and a signal receiver directly electrically connected to the LED module 20 . When the distance sensor 30 senses that the distance between the car 200 and the car 300 behind is less than a preset value, the signal transmitter sends a signal to the signal receiver, and the signal receiver starts the LED module 20 after receiving the signal ; When the distance sensed by the distance sensor 30 is always less than the preset value, the signal transmitter continues to send a signal to the signal receiver, so that the LED module 20 continues to start; when the distance sensed by the distance sensor 30 When the value is greater than the preset value, the signal transmitter will no longer send a signal to the signal receiver, and the LED module 20 will not start.

The brake warning light 100 can be activated in various ways, such as lighting, bouncing, flashing, beeping of the brake warning light 100, or even making the brake warning light 100 swing, etc., so that the brake warning light 100 is more attractive , to warn the car 300 behind to avoid in time. In the present embodiment, activation of the brake warning light 100 includes lighting of the brake warning light 100 . When the distance sensor 30 on the brake warning light 100 senses that the distance is less than a predetermined value, the brake warning light 100 is turned on immediately.

In other embodiments, the LED chip 22 of the LED module 20 in the brake warning light 100 can display different values, symbols or characters according to the different distances detected by the distance sensor 30 .

Further, the signal transmission unit may also include a signal processor. The signal processor is used to process different signals received by the signal receiver, and then activate different LED chips 22 in the LED module 20 . For example, the LED chip 22 can display different numbers according to different distance values sensed by the distance sensor 30 . In this embodiment, the LED module 20 includes nine LED chips 22 , and the thirty LED chips 22 are arranged in a rectangular array of six rows and five rows. A hundred digits from 0 to 99 can be displayed in the LED chips 22 of the array. Therefore, the signal transmission unit can be set to process the distance value of 0 to 100 meters sensed by the distance sensor 30 into an integer value through the signal processing unit, and control the start-up of the corresponding LED chip 22 in the LED module 20 , and then display the integer value of the distance according to the distance value sensed by the distance sensor 30 . Please refer to FIG. 3 , which shows a schematic diagram of these LED chips 22 displaying the number "23" by blinking in one embodiment. Further, the LED chip 22 in the LED module 20 can be set as an LED chip 22 that emits different lights, so that the tens and ones digits of the displayed numbers display different colors for distinction.

In other embodiments, the brake warning light 100 can not only be installed at the rear of the automobile 200 for warning the automobile behind from rear-end collision caused by the sudden braking of the automobile 200 in front, but can also be installed on the side of the automobile 200. , in order to prevent two parallel vehicles from colliding due to the close distance.

The brake warning light 100 provided by the embodiment of the present invention is installed on the automobile 200, and a distance sensor 30 is installed on it. When the distance sensor 30 detects that the distance between the automobile 300 and the automobile 200 is less than the preset value, the distance sensor 30 sends a signal to the brake warning light 100, so that the brake warning light is activated to warn the cars behind, which prevents the cars behind from continuing to drive because they don't know the sudden situation of the cars in front. The distance of the car is getting closer and closer, causing a rear-end accident.
