[0005] The technical problem to be solved by the utility model is to realize a high-mounted brake lamp that can display different colors.

[0006] To achieve the above object, the technical solution adopted by the utility model is: a high-mounted brake lamp, a light-transmitting mask is provided on the outer side of a strip-shaped housing. Installation brackets are provided at both ends inside the housing. A light source installation area and a slot for fixing a light guide bar are provided on the installation brackets. Both ends of the light guide bar are fixed in the slots. At least two different-color LED light sources are installed on the light source installation area, and the LED light sources all irradiate towards the light guide bar.

[0019] The following, with reference to the drawings, through the description of the embodiments, the specific embodiments of the utility model, such as the shapes, structures of the various components involved, the mutual positions and connection relationships between the various parts, the functions and working principles of the various parts, the manufacturing process and the operation and use methods, etc., are further described in detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the utility model.

[0020] The overall structure of the high-mounted brake light is as Figure 1 shown. One side of the strip-shaped housing 5 is open, and together with the mask 3, it forms a brake light assembly for placing components such as the light guide bar 2. The mask 3 is also strip-shaped as a whole, and both ends are fixed on the housing 5 through a snap structure. The overall size of the lamp is slightly longer than 50 cm, and it can be specifically designed according to the needs of the vehicle model. The effect is obvious during dynamic operation. The housing 5 is provided with a mounting structure for cooperating with the body sheet metal parts.

[0021] At both ends inside the housing 5, there are mounting brackets 4. On the mounting brackets 4, there are light source installation areas and card slots for fixing the light guide bar 2. The light source installation areas can fix the LED light source 1 and the circuit board used in cooperation with it. The end faces at both ends of the light guide bar 2 face the light source installation areas directly, so that the LED light source 1 can irradiate the light guide bar 2 directly. When the light guide bar 2 emits light sufficiently, there are laterally extending buckles at both ends of the light guide bar 2, and the light guide bar 2 is fixed in the card slot through the buckles, realizing the fixation of the light guide bar 2. There is a gap between the end faces at both ends of the light guide bar 2 and the LED light source 1, which can ensure the heat dissipation effect of the LED and avoid overheating. Inside the housing 5, there is a strip-shaped support frame for supporting the light guide bar 2. The back of the light guide bar 2 is fixed on the strip-shaped support frame, and the front faces the mask 3. In this way, the light guide bar 2 can be fixed in the housing 5 more reliably. Because the light guide bar 2 is a slender strip-shaped structure, reliable fixation can avoid the light guide bar 2 shaking during driving and reduce the probability of problems such as deviation, deformation, and abnormal noise.

[0022] LED light sources 1 are fixed in the light source installation areas of the mounting brackets 4 at both ends inside the housing 5, and two LED light sources 1 are installed in each light source installation area. Two different types of particles are arranged at both ends. One is red light that meets the light color regulations of brake lights, and the other is any other of the RGB three primary colors. For example, the two LED light sources 1 are a blue LED and a red LED respectively. Light-emitting LED particles are arranged at both ends to ensure uniform light emission when the light guide bar 2 is lit.

[0023] As Figure 2 shown, inside the housing 5 or inside the vehicle, there is an MCU for controlling the LED light source 1. The signal output end of the MCU is connected to each LED light source 1 through a signal line. The MCU controls the different LED particles at both ends to be lit in a specific timing sequence to achieve a color mixing and flowing effect. The high-level brake light that can participate in the rhythm effect mainly uses the traditional light guide light-emitting form. In addition to the original red light sources at both ends, an additional blue light source is added. According to the optical RGB color mixing principle, when receiving the vehicle rhythm signal, the blue light source and the red light source perform a bright and dark cycle in combination with different brightness and lighting timings to achieve a colorful color mixing effect, so as to improve the attractiveness of the motor vehicle under unlocking or other working conditions.

[0024] The specific working mode can be designed according to needs. For example, the LED light source 1 can adopt a 3PI N wire harness, with positive and negative electrodes + rhythm signal pins. When: 1 / The rhythm signal adopts a high-low level form; 2 / When it is in a low level or floating state, the high-level brake light performs conventional lighting. The MCU outputs signals respectively to control the two red LEDs on both ends to emit light. Generally, 2 pieces of 0.5W red light LED light sources 1 are used; 3 / When it is in a high level, the high-level brake light performs preset rhythm lighting. The MCU outputs signals respectively to control the red and blue LEDs on both ends to emit light alternately. When the red LED on one end is lit, only the blue LED on the other side is lit. Then, the supply current of the LED particles is adjusted according to a linear ratio (when the current on one side increases, the current on the other side decreases) to realize the movement of the mixed light area. The moving speed depends on the linear ratio of the current adjustment.

[0025] The present invention has been described exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
