DETAILED DESCRIPTION

[0037] In order to elaborate technical contents, realized objectives, and effects of the present disclosure, the following will further explain the present disclosure in combination with accompanying drawings and implementations. Apparently, implementations described herein are merely some implementations, rather than all implementations, of the present disclosure.

[0038] In the present disclosure, orientations or positional relationships indicated by terms “up”, “down”, etc., are all based on orientations or positional relationships illustrated in the accompanying drawings. These terms are mainly used to better describe the present disclosure and implementations thereof, and are not used to limit that an indicated device, element, or component must have a specific orientation, so these terms cannot be construed as limiting the present application.

[0039] Referring to FIG. 1, a light source module for an atmosphere light is provided in the present disclosure, and the light source module is disposed at an edge of a light-guiding glass 1. The light source module includes multiple light-guiding blocks 2 and light-emitting diode (LED) particles 4. The multiple light-guiding blocks 2 are arranged along a side edge of the light-guiding glass 1 to constitute a curved light-guiding structure 3, and the curved light-guiding structure 3 has a radian matching the side edge of the light-guiding glass 1. The LED particles 4 are disposed at at least one end of the curved light-guiding structure 3, and lights emitted by the LED particles 4 are uniformly dispersed by the light-guiding structure 3 to be incident into the light-guiding glass 1.

[0040] In the present disclosure, the light-guiding glass 1 may be a toughened or an ordinary inorganic glass, or an organic glass. An entire safety of a glass can be improved by selecting a structure of a laminated glass. The light-guiding glass 1 is a curved glass, and light-guiding glasses 1 of different vehicle models have different curvatures. In the present disclosure, each light-guiding block 2 is a transparent optical element made of a light-guiding material, preferably polycarbonate (PC) or poly(methyl methacrylate) (PMMA). The multiple light-guiding blocks 2 are disposed at the side edge of the light-guiding glass 1. In an idea of dividing the whole into parts, multiple independent light-guiding blocks 2 are arranged and combined to constitute the curved light-guiding structure 3, and the curved light-guiding structure 3 refers to a light-guiding-block set composed of all light-guiding blocks 2. In this way, multiple independent light-guiding blocks 2 are combined to constitute the curved light-guiding structure 3, so a position and an angle of each independent light-guiding block 2 can be adjusted according to curvatures of different light-guiding glasses 1 to adjust the radian of the curved light-guiding structure 3 to match glasses with different curvatures, such that the multiple light-guiding blocks 2 are universal and different light-guiding strips need not to be developed for different types of light-guiding glasses 1.

[0041] The LED particles 4 are light source elements that provides light for a glass. In an implementation, the LED particles 4 can be disposed at two ends of the curved light-guiding structure 3 as in a conventional solution. Referring to the related art, the LED particles 4 are disposed at two ends of a light-guiding strip, and lights are transmitted from the two ends of the light-guiding strip to a middle of the light-guiding strip, such that a light intensity at a position away from the two ends is bound to be attenuated.

[0042] In an implementation of the present disclosure, referring to FIG. 1, the light source module further includes at least one curved circuit board 5, and a circuit is disposed on a surface of the at least one curved circuit board 5. The LED particles 4 are uniformly distributed on the surface of the at least one curved circuit board 5, and the LED particles 4 are coupled with an external power source through the circuit on the surface of the at least one curved circuit board 5, such that the external power source can supply power to the LED particles 4 to make the LED particles 4 emit lights. In the implementation, the number of the LED particles 4 is equal to the number of the multiple light-guiding blocks 2. It can be understood that in other implementations, the number of the LED particles 4 may also be greater than the number of the multiple light-guiding blocks 2 to enhance an effect of adjusting atmosphere. The at least one curved circuit board 5 and the curved light guiding structure 3 can either form a directly fixed connection structure, or a relatively fixed connection structure, that is, the at least one curved circuit board 5 and the curved light-guiding structure 3 are fixed relative to each other through being fixed to other structures. In FIG. 1, the at least one curved circuit board 5 is implemented as two curved circuit boards 5, and the two curved circuit boards 5 are spliced to cover an entire curved light-guiding structure 3. A single curved circuit board 5 may also be used to cover the entire curved light-guiding structure 3. However, a radian and a length of a single curved circuit board 5 can be reduced and a difficulty of preparing the single curved circuit board 5 can be reduced by using multiple curved circuit boards 5. The LED particles 4 are uniformly distributed at the at least one curved circuit board 5, and at least one LED particle 4 exists between the each light-guiding block 2 and the at least one curved circuit board 5.

[0043] In the above implementation, referring to FIG. 2 to FIG. 5, the each light-guiding block 2 defines a concave portion 22, each LED particle 4 protrudes from the surface of the at least one curved circuit board 5, and each protrusion LED particle 4 is just accommodated in the concave portion 22 of the each light-guiding block 2, such that a distance between the each light-guiding block 2 and the at least one curved circuit board 5 is shortened, and more lights emitted by the each LED particle 4 enter the each light-guiding block 2, which enhances an luminous effect.

[0044] In the above implementation, referring to FIG. 2 to FIG. 5, the multiple light-guiding blocks 2 each are designed to have a protrusion column 21, the at least one curved circuit board 5 defines through holes 51 corresponding to the columns 21, and the column 21 of the each light-guiding block 2 penetrates through each through hole 51 to make the each light-guiding block 2 fixedly connected with the at least one curved circuit board 5. Specifically, the column 21 can be fixed to the at least one curved circuit board 5 by a hot staking process.

[0045] In the above implementation, the at least one curved circuit board 5 is disposed on a surface of the curved light-guiding structure 3 away from the side edge of the light-guiding glass 1. In other words, a plane where the surface of the at least one curved circuit board 5 is located may be substantially regarded as a plane perpendicular to the light-guiding glass 1, or the surface of the at least one curved circuit board 5 is substantially parallel to a plane where the light-guiding glass 1 is located and a side surface of the at least one curved circuit board 5 is opposite to the side edge of the light-guiding glass 1, that is, for example, referring to FIG. 9, a distance exists between the side surface of the at least one curved circuit board 5 and the side edge of the light-guiding glass 1 in the horizontal direction.

[0046] In the above implementation, referring to FIG. 6 to FIG. 9, the each LED particle 4 includes a light-emitting surface 41, the each light-guiding block 2 includes a light incident surface 23, and the light incident surface 23 faces the light-emitting surface 41, a projection of the light incident surface 23 on a plane parallel to the light incident surface 23 overlaps a projection of the light-emitting surface 41 on the plane parallel to the light incident surface 23, and an area of the light incident surface 23 is designed to correspond to an area of the light-emitting surface 41, such that lights emitted from the light-emitting surface 41 all enter the each light-guiding block 2. In other words, lights emitted by the each LED particle 4 are emitted through the light-emitting surface 41, and then incident into the each light-guiding block 2 through the light incident surface 23 of the each light-guiding block 2 to transmit.

[0047] In the above implementation, referring to FIG. 6 to FIG. 9, the each light-guiding block 2 further includes a light outlet surface 25, the light outlet surface 25 faces the side edge of the light-guiding glass 1, a projection of the light outlet surface 25 on a plane parallel to the light outlet surface 25 overlaps a projection of the side edge of the light-guiding glass 1 on the plane parallel to the light outlet surface 25, and the light outlet surface 25 is designed to correspond to the side edge of the light-guiding glass 1, such that lights emitting from the light outlet surface 25 are all guided into the light-emitting glass 1. In other words, after being transmitted in the each light-guiding block 2, the lights incident from the light incident surface 23 are emitted through the light outlet surface 25 and then all incident into the side edge of the light-guiding glass 1.

[0048] In a structural solution of the each light-guiding block 2, referring to FIG. 6 to FIG. 8, the each light-guiding block 2 has a corner structure of 90°. In this case, the at least one curved circuit board 5 is disposed below the curved light-guiding structure 3, and the plane where the surface of the at least one curved circuit board 5 is located can be substantially regarded to be parallel to the light guiding glass 1. In this case, the lights emitted by the each LED particle 4 are incident into the each light-guiding block 2 through the light incident surface 23 of the each light-guiding block 2, and the lights are dispersed and transmitted in the each light-guiding block 2. After being reflected by a reflecting surface 24 of 45°, the lights change a direction and are emitted from the light outlet surface 25 to enter an edge of the light-guiding glass 1 much close to the light outlet surface 25. The each LED particle 4 and the at least one curved circuit board 5 are disposed below the each light-guiding block 2, such that a longitudinal space is made use of and a lateral space at the edge of the light-guiding glass 1 is saved.

[0049] In another structural solution of the each light-guiding block 2, referring to FIG. 9, the light incident surface 23 is parallel to the light outlet surface 25, and the each light-guiding block 2 is correspondingly designed to have a cuboid structure, such that the lights emitted by the each LED particle 4 can be transmitted to the side edge of the light-guiding glass 1.

[0050] It can be understood that in other implementations, the each light-guiding block 2 can have a structure in other shapes, which is not limited in the implementations.

[0051] Generally, smaller arrangement distance between light-guiding blocks 2 of the implementations is better. However, if two adjacent light-guiding blocks 2 are arranged at a certain distance, although no light-guiding material and LED particle 4 exist between the two adjacent light-guiding blocks 2, a dark area which may be perceived by human eyes will not exist in a middle area, which is also an acceptable solution. A certain distance between two adjacent light guiding blocks 2 not only can reduce the number of light-guiding blocks 2 used and the number of LED particles 4 used, but also can reduce accuracy requirements when the light-guiding blocks 2 used are arranged and improve efficiency. Therefore, distance d between two adjacent light-guiding blocks 2 is preferably 0-20 mm. Distance d in FIG. 1 of the present disclosure is 20 mm, and distance d in FIG. 3 to FIG. 4 is about 0 mm.

[0052] An ambient glass is further provided in the present disclosure, and the ambient glass may be a vehicle sunroof glass, an ambient glass mounted on a building, etc. Referring to FIG. 10, the ambient glass includes a light-guiding glass 1 printed with a reflective pattern and the light source module of any of the above implementations. The light source module is configured to emit uniform lights from a side edge of the light-guiding glass 1 to an interior of the light-guiding glass 1. The reflective pattern may be a printed ink or other materials. Lights emitted by the light source module are homogenized by the multiple light-guiding blocks 2 to be incident into the light-guiding glass 1 and reach the reflective pattern on a glass surface, and then the lights are refracted and emitted, which results in playing a role in adjusting atmosphere. In addition, the ambient glass further includes an exterior glass 7. The exterior glass 7 is stacked with the light-guiding glass 1 and is configured to isolate the light source module from the outside, thereby having a protective function.

[0053] In the above implementation, referring to FIG. 10, the ambient glass further includes a cover plate 6. The cover plate 6 is connected with the exterior glass 7 and the light-guiding glass 1 through an adhesive 8, the cover plate 6, the exterior glass 7, and the light-guiding glass 1 cooperatively define an accommodation cavity, and the light source module is mounted in the accommodation cavity. Referring to FIG. 6, when the LED particles 4 are uniformly distributed on the surface of at least one curved circuit board 5, the multiple light-guiding blocks 2 are fixedly connected with the at least one curved board 5, and the multiple light-guiding blocks 2 are also fixedly connected with the cover plate 6. Referring to FIG. 7, the multiple light-guiding blocks 2 are fixedly connected with the at least one curved circuit board 5, and the at least one curved circuit board 5 is fixedly connected with the cover plate 6. Referring to FIG. 8, all of the multiple light-guiding blocks 2 and the at least curved circuit board 5 are fixedly connected with the cover plate 6. A manner of fixed connection may be clamp connection, screw connection and other fastener connection, or welding and any other fixed manners, which is not limited in the present disclosure.

[0054] In the above implementation, referring to FIG. 6 and FIG. 8, the multiple light-guiding block 2 each are provided with a protrusion 26, the cover plate 6 is provided with clamping portions 61, and the protrusion 26 is inserted into each clamping portion 61 to make each light-guiding block 2 fixed to the cover plate 6.

[0055] Since the present disclosure adopts the above technical solutions, the present disclosure has following beneficial effects.

[0056] The multiple independent light-guiding blocks are combined to constitute the curved light-guiding structure, so a position and an angle of each independent light-guiding block can be adjusted according to curvatures of different light-guiding glasses to adjust the radian of the curved light-guiding structure to match different glasses, such that the multiple light-guiding blocks are universal and different light-guiding strips need not to be developed for different types of atmosphere lights.

[0057] The light incident surface of the light-guiding block is designed to match the light-emitting surface of the LED particle, and the light outlet surface of the light-guiding block is designed to match the side edge of the light-guiding glass. No matter how a relative position of a circuit board and the light-guiding glass changes, the multiple light-guiding blocks can transmit all the lights emitted by the LED particles to the light-guiding glass.

[0058] The above description is only to provide a better implementation of the present disclosure, rather than to limit the present disclosure. The present disclosure is not limited to the above examples. Changes, modifications, additions, or replacements made by those of ordinary skill in the art within a substantive scope of the present disclosure also belong to the protection scope of the present disclosure.
