Detailed Description
The invention is further described below with reference to the accompanying drawings and specific examples.
In an embodiment, referring to fig. 1-3, an atmosphere lamp assembly comprises a base plate 1, a functional layer and a plurality of light emitting lamp caps 7, wherein the functional layer is attached to the outer surface of the base plate 1 in shape, and comprises a soft cushion layer 2, a reflecting layer 3, a light guide fiber woven layer 4, a light homogenizing layer 5 and an outer coating layer 6 which are sequentially attached from inside to outside layer by layer;
in this embodiment, each functional layer has different functions, wherein the most important natural function is the light guide fiber woven layer 4; the light guide fiber weaving layer 4 comprises warps and wefts which are woven in a staggered mode, and the light guide fiber weaving layer 4 formed by weaving is soft and similar to cloth; in order to improve the light emitting brightness of the atmosphere lamp assembly, preferably, the warp and the weft are both light guide fibers, and both ends of the light guide fibers are light inlet ends; the light inlet ends of the light guide fibers belonging to the same warp or weft are converged into a plurality of optical fiber bundle ends, and an optical fiber bundle sleeve 41 is sleeved outside each optical fiber bundle end to prevent the light guide fibers in the optical fiber bundle ends from being separated; each optical fiber bundle end is butted with one light-emitting lamp holder 7, light rays emitted by the light-emitting lamp holders 7 enter from the light inlet ends of the light guide fibers and are emitted outwards from the side surfaces of the light guide fibers, and finally, the light guide fiber braided layer 4 has a surface light-emitting effect macroscopically;
the soft cushion layer 2 is arranged on the innermost side of the functional layer and is attached to the outer surface of the bottom plate 1, so that a buffering effect and good safety can be achieved when a user accidentally collides, soft and resilient touch feeling is provided when the user touches the atmosphere lamp assembly, user experience is improved, and the soft cushion layer 2 is preferably a sponge layer;
the reflecting layer 3 is mainly used for reflecting light emitted inwards by the light guide fiber woven layer 4, because the side surface of the light guide fiber is 360-degree light emitting around, namely nearly half of the light is emitted to the inner side direction, the light can be reflected by adding the reflecting layer 3, and the light emitting brightness of the atmosphere lamp assembly can be obviously improved; the reflecting layer 3 may be in the form of a part, for example, a white soft light cloth is attached to the light guide fiber woven layer 4; or be attached to the cushion layer 2, such as white reflective paint sprayed on the outer surface of the cushion layer 2; the scheme of the white paint sprayed on the outer surface of the cushion layer 2 is preferred in the embodiment, the spraying process is simple, additional parts cannot be added, and the cost is reduced;

the outer cladding layer 6 is arranged on the outermost side of the functional layer, mainly plays a role in protecting other functional layers on the inner side, and also has a decorative effect because the outer cladding layer can be directly seen by naked eyes; the outer cladding layer 6 is provided with a preset light-transmitting pattern part, and light rays emitted by the light homogenizing layer 5 can be emitted to the outside from the light-transmitting pattern part; the outer cover 6 of this embodiment is preferably a skin with an engraved pattern.
In this embodiment, the light emitting lamp head 7 is a light source of an atmosphere lamp assembly, and includes a housing 71, and a circuit board module and a light mixing lens 72 disposed in the housing 71; the shell 71 is internally provided with a cavity for placing the circuit board module and a light-emitting cavity for communicating the cavity with the outside, wherein the light-emitting cavity comprises a beam sleeve cavity part connected with the optical fiber beam sleeve 41 and a lens cavity part for fixing the light-mixing lens 72; the circuit board module comprises a PCB 73 and RGB-LED lamp beads 74 fixed on the PCB 73; the light inlet end of the light mixing lens 72 is close to the RGB-LED lamp bead 74, and the light outlet end of the light mixing lens 72 is contacted and abutted with the optical fiber bundle end; the three color light rays emitted by the RGB-LED lamp beads 74 enter the light mixing lens 72 to mix light, and the mixed light enters the light inlet end of each light guide fiber in the optical fiber bundle end.
The atmosphere lamp assembly can be applied to scenes of objects which are large in area, have complex curved surface surfaces and need surface lighting, such as door plate interior trim on vehicles or non-planar advertisement displays; wherein, each functional layer is soft and can be adhered to the bottom plate 1 and changed along with the shape change of the bottom plate 1; compare the face light-emitting scheme that adopts the ya keli board, this embodiment atmosphere lamp assembly cost is lower, the security performance is better.
Although the present invention has been described with reference to preferred embodiments, it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and various changes in form and details may be made within the scope of the appended claims.
