Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamps, in particular to a high-brightness luminous vehicle logo device. Background Art

[0002] The car logo is an important symbol for identifying the vehicle and an important part of the car's exterior decoration. With the development of technology and the improvement of aesthetic requirements, luminous car logos are gradually becoming standard equipment for vehicles. The use of luminous car logos can facilitate the identification of car brands at night, help improve the appearance quality of the entire vehicle, and create a good brand image.

[0003] Existing luminous car logos usually use a mask with a light beam scattering effect to achieve uniformity of luminescence. Since the scattering coating or material will greatly reduce the luminous brightness, it cannot reach the same brightness level as the daytime running light. For example, a car logo luminous lamp disclosed in Chinese patent CN219955122U includes a lampshade, a decorative ring, a LOGO panel, a bracket, an LED circuit board and a shell. The lampshade and the shell are fixedly installed, and an installation cavity is formed between the lampshade and the shell. One side of the lampshade is set as the outer side, and one side of the shell is set as the inner side. The decorative ring, the LOGO panel, the bracket, and the LED circuit board are installed in the installation cavity from the outside to the inside. The LOGO panel is fixedly installed on the inner side of the decorative ring. The inner side of the decorative ring is fixedly connected to the bracket. The inner side of the bracket is fixedly provided with an LED circuit board, and the LED circuit board is provided with an LED light source. The LOGO panel is a milky white translucent material. The outer layer of the LOGO panel is provided with an aluminum layer. By arranging a reflective bowl structure on the bracket, the light emitted by the LED light source is evenly reflected to the LOGO panel, so that the car logo luminous lamp has a beautiful effect during the day and more uniform light at night. It can be seen that the luminous logo achieves luminous uniformity through the LOGO panel. However, the use of the LOGO panel made of milky white translucent material will greatly reduce the luminous brightness and cannot reach the same brightness level as the daytime running lights. Therefore, how to improve the utilization rate of light efficiency and achieve the effect of the luminous logo with the same brightness level as the daytime running lights is the current problem to be solved.

Specifically, a stretched concentrator optical structure 22 is provided on the rear end surface of the light guide 2 facing the light source PCB circuit board 3, that is, the light incident surface, and the stretched concentrator optical structure 22 is used to concentrate light to form a high-brightness luminous area; a light entrance groove 221 is provided on the stretched concentrator optical structure 22, and the light entrance groove 221 is used to collect light, and a plurality of optical pattern areas 2211 are provided on the bottom surface 2212 of the light entrance groove 221; the light source PCB circuit board 3 includes a plurality of evenly distributed LED light-emitting particles 32, one optical pattern area 2211 corresponds to one LED light-emitting particle 32, and the optical pattern area 2211 is used to diffuse the central light beam of the LED light-emitting particle 32 to improve the uniformity of the overall light emission; the light efficiency utilization rate is improved by stretching the concentrator optical structure 22, and a high-brightness luminous area is obtained without significantly increasing the light source power; the uniformity of the brightness of the luminous area is improved by the optical pattern area 2211.

Specifically, the second mounting structure 53 includes a mounting foot 531 and a snap-on buckle 532 disposed on the mounting foot 531, and a corresponding snap-on groove is disposed on the vehicle body grille. The snap-on buckle 532 snaps into the snap-on groove, so that the luminous vehicle logo device is mounted and fixed on the vehicle body grille. In this embodiment, three second mounting structures 53 are disposed at the rear of the frame 51, and one second mounting structure 53 is disposed on one side of each first mounting structure 52, and the extension piece 521 is connected to the mounting foot 531, and the strength of both is increased by the connection.

[0032] In order to improve the appearance, the modeling pattern area 11 is convex outward, so that the front end surface of the modeling pattern area 11 is higher than the front end surface of the non-modeling pattern area 12. Thus, the modeling pattern area 11 presents a three-dimensional layered feeling during the day.
