Ambient lights are mainly used to enhance the atmosphere, and there is also a kind of ambient light that also has the function of lighting warnings, such as door control warnings and seat belt warning lights. Ambient lights are usually placed in the dashboard, door panels, ceilings, and door pedals.

[0003] The basic structure of the atmosphere lamp known to the inventor includes a housing, a PCB board, a light guide plate, a reflective film, a uniform light film and a light-shielding aluminum plate. The PCB board, the light guide plate and the reflective film are arranged in the installation cavity of the housing, the light-shielding aluminum plate is arranged on the port of the housing, the uniform light film is arranged on the back of the light-shielding aluminum plate, and the PCB board has a light-emitting LED. The atmosphere lamp is connected to the circuit, the signal is turned on, the LED on the PCB is lit, the light is transmitted through the light guide plate and reflected on the reflective optical surface of the light guide plate and the reflective film, and then illuminates the area on the exterior surface that needs to be illuminated, thereby completing the lighting of the pattern on the film.

[0004] The existing ambient light extension is relatively limited, basically it is displayed by a single color of light, and there are also lights with multiple colors, but the internal structure is complex and the circuit layout is cumbersome. In addition, the existing parts assembly requires the use of double-sided tape and glue filling, and the process is time-consuming and long; by stamping the metal aluminum parts and then using UV glue to bond the stamped aluminum parts as the assembly appearance parts; after the PCB board and the wiring harness are welded, they are installed in the corresponding position of the shell, and the positioning on the shell ensures that the assembly position of the PCB board is accurate; the light guide plate is assembled with the reflective film and the uniform light film and installed on the shell, and the relative position of the light guide plate is also ensured by the positioning on the shell; the appearance parts and the assembled back shell are connected and sealed with glue, and the wire outlet holes of the back cover are sealed with glue. During the process, the sealing between the components may be poor, or the sealing is easy to decrease after a period of use. Summary of the invention

Of course, more than three luminous colors can be realized on this basis.

[0020] The light guide plate is preferably arranged in the following structure: the internal cavity of the bracket has a first partition and a second partition in sequence from top to bottom, the side of the bracket close to the PCB board is provided with a first plug-in port and a second plug-in port in sequence from top to bottom, the first light guide plate is arranged on the first partition through the first plug-in port, and the second light guide plate is arranged on the second partition through the second plug-in port.

[0021] To limit the movement of the light guide plate, the inner wall of the bracket has a first buckle and a second buckle, a gap for the first light guide plate to be inserted is formed between the first buckle and the first partition, and a gap for the second light guide plate to be inserted is formed between the second buckle and the second partition.

[0022] Furthermore, a first limiting plate for limiting the further insertion of the first light guide plate and a second limiting plate for limiting the further insertion of the second light guide plate are longitudinally arranged in the internal cavity of the bracket.
