Embodiment 1

[0043] Such as Figure 4 with Figure 5 As shown, a light emitting structure 6 capable of realizing various optical functions includes a moving carrier 1, a light source group 3 and a light guide 2, and the moving carrier 1 is suitable for driving the light source group 3 to perform reciprocating linear motion.

[0044] In this embodiment, the moving carrier 1 includes a mounting base 101a, a sliding bar 102a slidably connected to the mounting base 101a, and a driving mechanism for driving the sliding bar 102a to reciprocate. The light source group 3 is fixed on the sliding bar 102a, installed The seat 101a is fixed on the vehicle body 4 . A sliding groove 104a is provided on the mounting base 101a to ensure the linear motion of the sliding bar 102a. Since the sliding bar 102a needs to reciprocate, the length of the sliding groove 104a is greater than that of the sliding bar 102a, and the light sources of different colors are arranged along the moving direction of the sliding...

Embodiment 2

[0048] Such as Image 6with Figure 7 As shown, the light source group 3 in this embodiment is installed on the endless transmission belt 101b, and the movement track of the endless transmission belt 101b is a track shape, and the endless transmission belt 101b is tightened by two power wheels 102b, and the power wheels 102b can be fixed with the car body 4 One of the power wheels 102b is driven by the driving motor 103b to rotate, and the other power wheel 102b rotates as a driven wheel. The light source group 3 is evenly distributed on the endless transmission belt 101b. The arrangement of the light source group 3 is the same as that in the first embodiment. Since the endless transmission belt 101b is constantly circulating, the light source can completely cover the endless transmission belt 101b.

Embodiment 3

[0050] The moving carrier 1 in this embodiment is a polyhedral structure 101c rotating around the central axis 102c, and the cross section of the moving carrier 1 is a regular polygon. The light source group 3 is installed on the outer surface of the moving carrier 1 .

[0051] Such as Figure 1-Figure 3 The moving carrier 1 shown has a hexagonal prism structure, and its end face is a regular hexagon. The driving source drives the central axis 102c of the moving carrier 1 to rotate, so that the light source group 3 installed on the moving carrier 1 rotates.

[0052] There are two ways to arrange the light source group 3 on the moving carrier 1:

[0053] The first arrangement is as figure 1 with figure 2 As shown, the light source group 3 is installed on a surface parallel to the central axis 102 c on the moving carrier 1 , and light sources of different functional colors are located on different sides of the moving carrier 1 . The light source group 3 is installed on six s...

Abstract

The invention discloses a light-emitting structure capable of achieving multiple optical functions and a vehicle lamp. The light-emitting structure comprises a moving carrier, a light source set and a light guide body fixed to a vehicle body. The light source set is composed of a plurality of light sources with different functional colors, and the moving carrier drives the light source set to move and adjusts the light sources with the different functional colors to be right opposite to the light guide body so that the light-emitting structure can display different functions. According to the light-emitting structure capable of achieving the multiple optical functions and the vehicle lamp, by changing the positions of the light sources, the light sources with different functional colors are moved to a certain characteristic position and then matched with the light guide body, the different optical functions are achieved, the structure is simple, and the occupied space is small.

Description

technical field [0001] The invention relates to the technical field of vehicle lighting, in particular to a light-emitting structure capable of realizing various optical functions and a vehicle lamp. Background technique [0002] With the advancement of LED technology, LED light sources are currently widely used in the car lighting industry. Due to market competition and the needs of consumer groups, the functions of car lights have evolved into more and richer changes and applications. Different design structures Different functional effects can be reflected on the car lights. Taking the thick-walled light guide as an example, the combination of thick-walled light guide and LED light source can realize multiple light colors or multiple functional distributions on the same light-emitting surface. [0003] In the existing technology, in order to achieve different light colors or functions in a unified light-emitting area, a single-chip front-to-back distribution or a multi-c...
