Vehicle ambient lighting

Abstract

The invention discloses a vehicle ambient lighting. The vehicle ambient lighting is characterized by comprising a shell, a support, a first light guide plate, a first shading film, a second light guide plate, a PCB and a shading plate, and the first shading film is arranged on the back face of the first light guide plate; the second light guide plate is positioned below the first light guide plate; the PCB is arranged on one side of the support and at least provided with a first LED lamp and a second LED lamp, the first LED lamp is close to the first light guide plate, and the second LED lampis close to the second light guide plate; the shading plate is arranged at a port of the shell to package the first light guide plate, the second light guide plate and the support in the shell, and the shading plate is provided with a first area pattern and a second area pattern which can transmit light. The PCB is provided with the LED lamps with at least two colors, the light-emitting styles ofthe patterns can be controlled through the corresponding light guide plates, pattern display incompatible with multiple colors is achieved, and the internal structure is compact and reasonable.

Description

technical field [0001] The invention relates to a vehicle interior decoration, in particular to a vehicle atmosphere lamp. Background technique [0002] People have higher and higher requirements for the personalization of vehicle interiors, so the application of ambient lights in vehicle interiors is becoming more and more common. The ambient light is mainly used to enhance the atmosphere, and there is also an ambient light that also serves as a lighting warning, door control warning, and seat belt warning light. Ambient lights are usually placed on the instrument panel, door panels, ceiling 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. On the port of the shell, the light uniform film is arranged on the back of the light-shielding aluminum plate, and there are LEDs that can emit light on the PCB. ...

AI Technical Summary

Problems solved by technology

[0004] The extension of the existing atmosphere lights is relatively limited. Basically, they are displayed with a single color of light, and there are also lights of multiple colors, but the internal structure is complicated and the wiring layout is cumbersome.

In addition, the existing parts assembly needs to be pasted with double-sided tape and glued, and the process takes a long time; by stamping and forming the metal aluminum parts, use UV glue to bond the stamped aluminum parts as an assembly Appearance parts; after soldering the PCB board and the wire harness, put them into the corresponding position of the shell, and ensure the correct assembly position of the PCB board through the positioning on the shell; assemble the light guide plate, reflective film and uniform light film into the shell together In addition, the positioning on the shell is also used to ensure that the relative position of the light guide plate is accurate; the appearance parts and the assembled back shell are connected and sealed with glue, and the outlet holes of the wiring harness at the back of the back cover are glued and sealed. Maybe the sealing is not good, or the sealing is easy to drop after a period of use
