Automobile atmosphere lamp with variable transmissivity

Abstract

The invention belongs to an automobile lamp, and particularly relates to an automobile atmosphere lamp with variable transmissivity, which changes the color in an automobile and the transmissivity of the automobile atmosphere lamp through an electrochromic device so as to change the light intensity of an automobile trim. The automobile atmosphere lamp comprises an optical module (1), a light source driving module (2), an electrochromic module (3), an electrochromic driving module (4), a cover plate (5) and a shell (6), wherein the light source driving module (2), the electrochromic driving module (4), the optical module (1) and the electrochromic module (3) are all arranged in the shell (6); the light source driving module (2) is electrically connected with the optical module (1); the electrochromic driving module (4) is electrically connected with the electrochromic module (3); the optical module (1) and the electrochromic module (3) are connected with the cover plate (5), and the cover plate (5) is connected with the shell (6).

Description

technical field [0001] The invention belongs to an automobile lamp, in particular to an automobile atmosphere lamp with variable transmittance. Background technique [0002] With the popularity of automobiles, people's requirements for automobiles are no longer limited to driving performance and safety performance, and they are paying more and more attention to the personalization and comfort of automobiles. As a kind of widely favored automotive interior decoration lights, car ambient lights have been applied in many car models, mainly divided into monochromatic ambient lights and multi-color ambient lights. For multi-color ambient lights, it can cooperate with different photoelectric control strategies to emit different colors of light under different driving conditions, especially when driving at night, which can increase the experience of car drivers and passengers. [0003] Car atmosphere lights are classified according to the light source, which can be divided into la...

Problems solved by technology

For the laser ambient light, the laser light source is used with the flexible optical fiber. The laser light source emits light and is exported through the optical fiber. Its advantages are uniform light emission, small fiber diameter, low light attenuation, long light guide distance, simple design, but high cost.

As for the LED ambient light, there are mainly two schemes. The first one is to use LED light source and hard light guide to realize. The LED light source adopts side-emitting light and is placed on one side of the light guide. , which has the advantages of low cost and mature technology, but high light attenuation, short light guide distance, and large diameter opening; the second is realized by using LED light source and silicone soft light guide. , surrounded by white opaque silica gel, and then filled with silica gel, the light emitted by the light source is directly transmitted through the silica gel. many, high cost

However, the optical components of these three ambient light solutions are exposed, directly visible to the occupants of the car, without metallic color, and the appearance color of the optical components cannot be changed, especially during the day, which affects the driving experience
