Detailed Description

In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Referring to fig. 1 and 2, the embodiment of the present application provides a flat panel light fixture 100, and the flat panel light fixture 100 may be used for illumination, decoration, and the like. The flat panel lamp 100 includes a light-transmitting housing 10, a light guide plate module 30, and a light source module 50. The light guide plate module 30 and the light source module 50 are disposed in the light-transmitting housing 10, and the light source module 50 is configured to emit light, which is guided out through the light guide plate module 30 and transmitted to the outside through the light-transmitting housing 10, so as to achieve a decorative or/and illumination effect.

Referring to fig. 3, in the present embodiment, the light-transmitting housing 10 may have a substantially flat plate shape, which is used to define the overall outline shape of the flat panel lamp 100. The light-transmitting housing 10 is provided with a receiving cavity 101, and the receiving cavity 101 is used for receiving the light guide plate module 30 and the light source module 50. The light-transmitting housing 10 is made of a light-transmitting material, for example, the material of the light-transmitting housing 10 may include inorganic glass, organic polymer, fiber nanocomposite, and the like. As an example, the light-transmitting housing 10 may be made of at least one material selected from glass fiber reinforced plastic, resin, acryl, etc., so that the light-transmitting housing 10 may be substantially transparent or translucent so that light inside the light-transmitting housing is transmitted out, resulting in a clearer light profile.

In the present embodiment, the light-transmitting housing 10 includes a light-guiding panel 12 and at least one first light-guiding side 14.

The light guide panel 12 is used as an outer surface of the flat panel lamp 100, and has a substantially flat plate shape. The light guide panel 12 is used for covering the light guide plate module 30 and allowing light in the light guide plate module 30 to transmit to the outside through the light guide panel 12, so as to form a surface-emitting light effect. The specific outline of the light guide panel 12 may be polygonal, such as triangle, quadrangle, pentagon, hexagon, etc., and may also be other irregular patterns, for example, the outline of the light guide panel 12 is a pattern defined by straight line segments and curved line segments together, etc., and in the illustrated embodiment, the outline of the light guide panel 12 is substantially regular hexagon. It should be understood that the specific contours of the light guide panel 12 should not be limited to the examples listed in this specification.

The first light guiding side 14 is disposed on a side of the light guiding panel 12 facing the accommodating cavity 101, the first light guiding side 14 is configured to allow light of the light source module 50 to pass through, and when the light of the light source module 50 passes through the first light guiding side 14 and passes through to the outside, a linear luminous light effect can be formed. In the present embodiment, the first light guiding side 14 is substantially in a strip shape, and the dimension in the length direction thereof may be substantially greater than the dimension in the width direction or the thickness direction, for example, the dimension in the length direction of the first light guiding side 14 is greater than three times the dimension in the width direction, so that the structure thereof is substantially in a strip shape, thereby being used for guiding out light to form the light effect of line illumination. The first light guiding side 14 is fixedly connected to the light guiding panel 12 and protrudes with respect to the surface of the light guiding panel 12, and specifically, the first light guiding side 14 may be substantially perpendicular to the light guiding panel 12. Therefore, the first light guiding side 14 is located in the accommodating cavity 101 and divides the accommodating cavity 101 into at least two accommodating chambers 1011, and the accommodating chambers 1011 are used for accommodating the light guiding plates in the light guiding plate module 30.

In the embodiment of the present application, the number of the first light guiding sides 14 should not be limited by the specification or the drawings in the specification, and the number may be one or more. Specifically, the number of the first light guiding sides 14 may be N, where N is a positive integer greater than or equal to 1, for example, N is 2 or greater than 2. By providing N first light guiding sides 14, the housing cavity 101 may be divided into at least N housing chambers 1011, so that at least N corresponding light guiding plates are provided. The N first light guiding sides 14 may also form N light emitting lines, which is beneficial to enriching the light effect of the flat panel lamp 100. In this embodiment, the N first light guiding sides 14 are arranged at intervals on the surface of the light guiding panel 12. As an example, the N first light guiding sides 14 may be arranged substantially radially about a predetermined center point O. For example, each first light guiding side 14 may include a first end 141 and a second end 143 opposite to each other, where the first ends 141 of the N first light guiding sides 14 are connected to each other, and the connection node of the first ends 141 of the N first light guiding sides 14 is a predetermined center point O, and the second end 143 of each first light guiding side 14 extends in a direction away from the center point O. Since the first light guiding side 14 is substantially flat in this embodiment, the above arrangement makes the N first light guiding sides 14 radially arranged about the center point O. The included angle between each adjacent two of the first light guiding side edges 14 is substantially the same, i.e. the distance between the second ends 143 of each adjacent two of the first light guiding side edges 14 is substantially the same. In particular, in the embodiment shown in fig. 3, the number of the first light guiding sides 14 is three, and the three first light guiding sides 14 are arranged in a substantially linear radial manner with respect to the center point O. Of course, in other embodiments, the first light guiding side 14 may also be in an arc shape, for example, when the first light guiding side 14 is in an arc shape, the N first light guiding sides 14 are arranged in a spiral radial shape with respect to the center point O; for another example, when the first light guiding side edges 14 are wavy, the N first light guiding side edges 14 are radially arranged outwards in a wavy manner with respect to the center point O.

The N first light guiding sides 14 may be assembled or integrally formed. For example, the first ends 143 of the N first light guiding sides 14 are all connected together (i.e., at the center point O), or the first ends 143 of the N first light guiding sides 14 may be disposed substantially around the center point O but spaced apart from each other. The N first light guiding sides 14 and the light guiding panel 12 may be assembled or integrally formed. For example, the light guide panel 12 and the first light guide side 14 are connected together by an adhesive or a fastener after being respectively molded; alternatively, the light guide panel 12 and the first light guide side 14 are made of the same material through an injection molding process or a compression molding process, and the light-transmitting housing 10 is formed as a unitary structure.

In this embodiment, the light-transmitting housing 10 may further include a second light guiding side 16, where the second light guiding side 16 is disposed on a side of the light guiding panel 12 facing the accommodating cavity 101. The second light guiding side 16 is used for allowing the light of the light source module 50 to pass through, and when the light of the light source module 50 passes through the second light guiding side 16 and passes through to the outside, the linear luminous light effect can be formed. In the present embodiment, the second light guiding side 16 is substantially strip-shaped, and the dimension in the length direction thereof may be substantially greater than the dimension in the width direction or the thickness direction, for example, the dimension in the length direction of the second light guiding side 16 is greater than three times the dimension in the width direction, so that the structure thereof is substantially strip-shaped, thereby being used for guiding out light to form the light effect of line illumination. The second light guiding side 16 is fixedly connected to the light guiding panel 12 and protrudes with respect to the surface of the light guiding panel 12, and in particular, the second light guiding side 16 may be substantially perpendicular to the light guiding panel 12.

In the embodiment of the present application, the number of the second light guiding sides 16 should not be limited by the specification or the drawings in the specification, and the number may be one or more. When the number of the second light guiding sides 16 is plural, the plural second light guiding sides 16 are sequentially connected end to jointly define the accommodating cavity 101. Specifically, the number of the second light guiding sides 16 may be M, where M is a positive integer greater than or equal to 2, for example, M is 2 or greater than 2, and M is an integer multiple of N. The (M/N) second light guiding sides 16 are sequentially connected between the two adjacent first light guiding sides 14, such that the (M/N) second light guiding sides 16 and the two first light guiding sides jointly surround and define a corresponding accommodating chamber 1011, and the accommodating chamber 1011 is used for accommodating a corresponding light guiding plate in the light guiding plate module 30. The M second light guiding sides 16 may also form M light emitting lines, and the light emitting surfaces formed by the light guiding plates corresponding to the light emitting lines formed by the M second light guiding sides 16 and the N first light guiding sides 14 may customize various light effects: for example, the solid geometry light effect is formed, which is beneficial to enriching the light effect expression of the flat panel lamp 100.

In the embodiment shown in fig. 3, the number of the second light guiding sides 16 is six, the number of the first light guiding sides 14 is three, and each two second light guiding sides 16 are sequentially connected between two adjacent first light guiding sides 14, so that the two second light guiding sides 16 and the two first light guiding sides 14 jointly encircle to define a corresponding accommodating chamber 1011. When the plurality of light guide plates in the light guide plate module 30 are respectively disposed in the corresponding receiving chambers 1011, it is advantageous to form a hexahedral solid geometry light effect. In the present embodiment, the M second light guiding sides 16 and the light guiding panel 12 may be assembled or integrally formed. For example, the light guide panel 12 and the second light guide side 16 are separately formed and then joined together by an adhesive or a fastener; alternatively, the light guide panel 12 and the second light guide side 16 are made of the same material by an injection molding process, a compression molding process, or the like.

Referring to fig. 4, the light guide plate module 30 is disposed in the accommodating cavity 101 of the light-transmitting housing 10, and is used for guiding the light of the light source module 50 to the light-transmitting housing 10, so as to form the light effect of the light emitting surface after the light penetrates the light-transmitting housing 10 and is emitted. The light guide plate module 30 includes at least two light guide plates 32 disposed at intervals, and the at least two light guide plates 32 are arranged on the same plane so as to form a surface-emitting light effect. When the two light guide plates 32 are arranged in the accommodating cavity 101, the light guide panel 12 covers the light emitting surface of the light guide plate module 30/the light guide plate 32. The light guiding gap 301 is formed between two adjacent light guiding plates 32, the light guiding gap 301 is used for accommodating the first light guiding side edge 14, when the first light guiding side edge 14 is disposed in the light guiding gap 301, part of light of the light source module 50 can be sequentially emitted through the light guiding plates 32 and the light guiding panel 12 to form a light emitting surface, and meanwhile, other part of light of the light source module 50 can be emitted through the first light guiding side edge 14 to form a light emitting line, so that a light effect of combining the light emitting surface and the light emitting line can be formed. When the brightness of the light rays corresponding to the at least two light guide plates 32 is different, since the light emitting line formed by the first light guide side 14 is between the two light guide plates 32, the light emitting line can be highlighted between the at least two light emitting surfaces, and the combination of the at least two light emitting surfaces and the light emitting line can form a stereoscopic light effect with a more layered sense (as in the example shown in fig. 5), so that the light effect expression of the flat panel lamp 100 can be enriched.

Referring to fig. 4 again, in the embodiment of the present application, the number of the light guide plates 32 is N, where N is a positive integer greater than or equal to 1, for example, N is 2 or greater than 2. The number of the light guide plates 32 may be substantially the same as the number of the first light guide sides 14, so that the N light guide plates 32 are disposed in the N accommodating chambers 1011 formed by the N first light guide sides 14 in a one-to-one correspondence manner, such that the N light guide plates 32 are sequentially distributed around a predetermined center point O, and each of the first light guide sides 14 is located between two adjacent light guide plates 32. The light guide plates 32 in this embodiment are provided with three light guide sides 14, the light guide plates 32 are of a diamond structure, the three light guide plates 32 are sequentially distributed around a predetermined center point O, and can form a regular hexagonal light emitting surface structure together, when the light of the light source module 50 is emitted through the three light guide plates 32 and the three first light guide sides 14, the combination of the light emitting surfaces and the light emitting lines can form a visual stereoscopic light effect as shown in fig. 6, in which a stereoscopic hexahedral graph (in which different gray scales are used to reflect the color or brightness difference between different light emitting surfaces) can be observed from human eyes.

Referring to fig. 4 again, the light guide plate 32 includes a light incident surface 321 and a light emergent surface 323, the light emergent surface 323 is disposed opposite to the light guide panel 12, and the light incident surface 321 is configured to allow light of the light source module 50 to enter and the incident light is emitted from the light emergent surface 323. In the present embodiment, the light-incident surface 321 is provided as a peripheral wall of the light guide plate 32 substantially along the thickness direction of the light guide plate 32, and is adjacent to the light-emitting surface 323.

Further, the light guide plate 32 may further include a back surface 325 (fig. 2) facing away from the light emitting surface 323, the back surface 325 is located at a side of the light guide plate 32 facing away from the light guide panel 12, and the light inlet 321 is connected between the back surface 325 and the light emitting surface 323. The back 325 is provided with a texture reflecting net structure, and the texture reflecting net structure is used for diffusing light rays in the light guide plate 32, so that the condition of specular reflection can be broken through the texture reflecting net structure, when the light rays of the light source module 50 enter the light guide plate 32 through the light inlet surface 321, the light rays can diffuse to various angles due to the action of the texture reflecting net structure when the light rays propagate in the light guide plate 32, and the light rays can uniformly exit through the light outlet surface 321 to form a light emitting surface with uniform brightness.

Referring to fig. 7 to fig. 9, in the present embodiment, the light incident surface 321 is disposed at a side of the light guide plate 321 away from the light guide gap 301, so as to avoid the light incident surface 321 being located between the light guide plates 32, thereby facilitating the layout of the light emitting units of the light source module 50. In contrast, the light inlet surface 321 is located at the opposite outer side of the light guide plate 32, that is, the light inlet surface 321 of one light guide plate 32 is located at the side of the light guide plate 32 not adjacent to the other light guide plates 32, so that the light inlet surface 321 is disposed at a distance from the inner wall of the second light guiding side 16 of the light-transmitting housing 10, a predetermined gap 160 is formed between the light inlet surface 521 and the corresponding second light guiding side 16, and the predetermined gap 160 is used for accommodating a part of the structure of the light source module 50, so that the structure of the flat lamp 100 is more compact.

Further, the light guide plate 32 further includes a plurality of side surfaces 327 (fig. 4), the side surfaces 327 are connected between the back surface 325 and the light emitting surface 323, and the light entering surface 321 and the plurality of side surfaces 327 together form an outer sidewall of the light guide plate 32. The side surface 327 is located on a side of the light guide plate 32 facing the light guide gap 301, and the side surface 327 of one light guide plate 32 is disposed at a distance from the side surface 327 of the light guide plate 32 adjacent to the light guide plate 32. The light guide plate 32 may include a plurality of light incident surfaces 321, for example, two or more light incident surfaces 321 and side surfaces 327, which together define the outer contour of the light guide plate 32 into a polygonal geometry, so as to facilitate formation of stereoscopic light effect. In the present embodiment, the light guide plate 32 has a substantially diamond shape, and one light guide plate 32 includes two light inlet surfaces 321 and two side surfaces 327, and the length dimensions of the light inlet surfaces 321 and the side surfaces 327 are substantially the same.

Further, the light guide plate module 30 may further include a light reflecting layer 34, wherein the light reflecting layer 34 is disposed on at least one of the back surface 325 and the side surface 327, and the light reflecting surface of the light reflecting layer 34 is disposed toward the inside of the light guide plate 32 for re-reflecting the light propagating to the back surface 325 and/or the side surface 327 to the inside of the light guide plate 32. The retroreflective layer 34 may be retroreflective paper that may be attached to the back 325 or/and the side 327. Alternatively, the light reflective layer 34 may be a reflective coating applied to the back 325 or/and the side 327. By providing the light reflecting layer 34, light can be prevented from leaking from the side surface of the light guiding plate 32 except the light emitting surface 323, for example, when the light reflecting layer 34 is provided on the side surface 327, light can be prevented from leaking into the light guiding gap 301 through the side surface 327, so that gap light mixing is effectively avoided, and the outline of the light emitting surface formed by the light guiding plate 32 is clear; by providing the light reflecting layer 34, light loss during propagation of light in the light guide plate 32 can be reduced, and the light utilization rate is high.

The light source module 50 is disposed on a side of the light guide plate module 30 facing away from the light guide panel 12. In the embodiment, referring to fig. 10 and 11, the light source module 50 includes a first light source 52 and a second light source 54, the first light source 52 is disposed opposite to the light-in surface 321 of the light guide plate 32, the light emitted by the first light source 32 enters the light guide plate 32 through the light-in surface 321, and is emitted through the light-out surface 323 and the light guide panel 12, and the light of the second light source 54 is emitted through the first light-guiding side 14. The first light source 52 and the second light source 54 respectively provide incident light for the light guide plate 32 and the first light guide side 14, so that the combined light effect of surface light emission and side light emission can be realized, and the light of the first light source 52 and the light of the second light source 54 can be respectively and independently controlled, thereby being beneficial to realizing multiple light effects. Further, since the second light source 54 provides the incident light for the first light guiding side 14 alone, the brightness of the first light guiding side 14 can be customized according to the requirement, when the color or brightness of the second light source is different from that of the first light source 12, the display of the light emitting line of the first light guiding side 14 is more prominent compared with the light emitting surface on the light guiding panel 12, the light emitting line is combined with the light emitting surfaces corresponding to the at least two light guiding panels 32, so that the three-dimensional light effect can be formed, and the light effect expression of the flat panel lamp 100 is enriched.

In the embodiment shown in fig. 11, the light source module 50 may further include a substrate 51, the substrate 51 is disposed on a side of the light guide plate module 30 facing away from the light guide panel 12, and the first light source 52 and the second light source 54 are disposed on the substrate 51. The substrate 51 may be a printed circuit substrate on which conductive traces may be provided for electrical connection with the first light source 52 and the second light source 54. The first light source 52 is disposed on a side of the substrate 51 facing the light guide plate 32, and is disposed at an edge portion of the substrate 51. Since the light inlet surface 321 of the light guide plate 32 is located between the light outlet surface 325 and the substrate 51, the first light source 52 can be disposed towards the light inlet surface 321, and the first light source 52 and the light guide plate 32 are substantially arranged on the same plane, so that the size of the flat panel lamp 100 in the thickness direction can be effectively reduced. In the present embodiment, the number of the first light sources 52 is plural, the plurality of first light sources 52 are disposed in one-to-one correspondence with the plurality of light incident surfaces 321, and the light of each first light source 52 is incident into the light guide plate 32 through the corresponding light incident surface 321.

The first light source 52 includes a plurality of first light emitting units 521, and the plurality of first light emitting units 521 are sequentially arranged at intervals along the extending direction of the corresponding light incident surface 321. The first light emitting unit 521 may be an LED light emitting unit, and a light emitting side thereof is disposed toward the light incident surface 321. Since the light-entering surface 321 is disposed opposite to the inner wall of the second light-guiding side 16 of the light-transmitting housing 10 at a distance, a predetermined gap 160 is formed between the light-entering surface 521 and the corresponding second light-guiding side 16, and therefore, the plurality of first light-emitting units 521 are disposed in the predetermined gap 160, and the first light-emitting units 521 face away from the second light-guiding side 16, so that as much light of the first light source 52 as possible can be incident on the light-guiding plate 12.

Further, referring to fig. 9 again, in order to avoid the light of the first light source 52 from leaking out through the predetermined gap 160, the flat panel light fixture 100 may further include a light shielding layer 72, and the light shielding layer 72 may be located on a side of the first light source 52 facing away from the substrate 51. Specifically, when the first light source 52 is disposed in the predetermined gap 160 and the light guide panel 12 is covered above the predetermined gap 160, when light from the first light source 52 enters the light entrance surface 321 along the plane of the substrate 51, a small portion of the light may be reflected by other portions and propagate in a direction away from the substrate 51, and at this time, by disposing the light shielding layer 72 on a side of the first light source 52 away from the substrate 51, for example, between the first light source 52 and the light guide panel 12, the light emission of this portion can be blocked, and while ensuring the light utilization efficiency to some extent, a space is provided between the light emitting surface formed by the light guide panel 32 and the light emitting line formed by the second light guide side 16, so that a contrast is formed, and the stereoscopic impression of the generated pattern is more remarkable in the full-bright state of the flat lamp 100, as shown in fig. 12.

Further, in the present embodiment, the light transmittance of the light shielding layer 72 is smaller than that of the light guide plate 32, and is smaller than that of the light guide panel 12, so as to shield light to form a display light effect of a bright-dark contrast. The light shielding layer 72 may be made of a non-transparent material, such as a light shielding material, and the specific form thereof may be: a light shielding coating, a light shielding tape, a light shielding cloth, a light shielding plate, and the like. The light shielding layer 72 may be attached to the inner surface of the light guiding panel 12 and correspondingly cover the predetermined gap 160, or the light shielding layer 72 may be attached to the outer surface of the light guiding panel 12, or the light shielding layer 72 itself may be a plate made of a light shielding material and fixed in the light transmitting housing 10.

Referring to fig. 11 again, in the present embodiment, the flat panel lamp 100 may further include a diffusion plate module 74, and the diffusion plate module 74 is disposed between the light guide panel 12 and the light guide panel module 30 of the light-transmitting housing 10. The diffusion plate module 74 is used for diffusing the light emitted from the light guide plate module 30 so as to make the light of the light emitting surface more uniform. The diffusion plate module 74 may also be used to mount the light shielding layer 72, for example, the diffusion plate module 74 may cover the predetermined gap 160, and the light shielding layer 72 may be disposed on a side of the diffusion plate module 74 facing away from the predetermined gap 160 or a side facing toward the predetermined gap 160.

As an example, the diffusion plate module 74 may include at least two diffusion plates 741 disposed at intervals from each other, and the at least two diffusion plates 741 are arranged on the same plane. The diffusion plate 741 may be a diffusion plate, in which chemical particles may be disposed as diffusion particles, so that light is continuously refracted, reflected and scattered in two mediums with different refractive indexes when passing through the diffusion layer, thereby generating an optical diffusion effect. Or, the diffusion plate 741 may be a microstructure light diffusion plate, and the surface of the diffusion plate may be provided with microstructure features arranged in an array, so that light rays are refracted in different directions when passing through, the light travelling route is changed, light rays are fully scattered, and a softer and uniform irradiation effect is achieved, wherein the microstructure array may comprise at least one of the following structures: v-shaped groove arrays, U-shaped convex groove arrays, pyramid arrays, circular ring arrays, microlens arrays and the like. The number of the diffusion plates 74 is the same as that of the light guide plates 32, and at least two diffusion plates 74 are stacked on at least two light guide plates 32 in a one-to-one correspondence manner, so as to make the light emitted from the corresponding light guide plates 32 more uniform. Further, a through groove 7410 is formed between two adjacent diffusion plates 741, the through groove 7410 is opposite to and communicates with the corresponding light guiding gap 301, and the through groove 7410 is used for partially accommodating the corresponding first light guiding side 14. The first light guiding side 14 is disposed through the corresponding through slot 7410 and the corresponding light guiding gap 301, so as to be exposed on a side of the light guiding plate 32 away from the light guiding plate 12, so as to guide out the light of the second light source 54.

The second light source 54 is fixed to a side of the substrate 51 facing away from the light guide plate module 30. In this embodiment, the substrate 51 is provided with the avoidance groove 510, the avoidance groove 510 is opposite to and communicates with the corresponding light guiding gap 301, and the second light source 54 is disposed adjacent to the avoidance groove 510. The first light guiding side 14 sequentially penetrates through the through groove 7401, the light guiding gap 301 and the space avoiding groove 510 and is exposed on one side of the substrate 51 away from the light guiding plate module 30, so that the light of the second light source 54 can enter and penetrate through the first light guiding side 14 to exit. The number of the second light sources 54 may be the same as the number of the first light guiding sides 14, for example, the number of the second light sources 54 is multiple, the multiple second light sources 54 are disposed in one-to-one correspondence with the multiple first light guiding sides 14, and the light of each second light source 54 is emitted to the external environment through the corresponding first light guiding side 14, so as to form the light effect of the light emitting line.

Referring to fig. 13 and 14, in the present embodiment, to increase the light utilization rate of the second light source 54, the first light guiding side 14 may be exposed on a side of the substrate 51 facing away from the light guiding plate 32, for example, an end surface of the first light guiding side 14 is flush with a surface of the side of the substrate 51 facing away from the light guiding plate 32, so that the light of the second light source 54 located on the side of the substrate 51 can be directly incident on the first light guiding side 14.

In other embodiments, the first light guiding side 14 may protrude from a side of the substrate 51 away from the light guiding plate module 30, so that a part of the structure of the first light guiding side 14 and the second light source 54 may be disposed at opposite intervals, so that the light of the corresponding second light source 54 may be directly incident to the first light guiding side 14, the efficiency of light guiding is higher, and the brightness of the light emitting line corresponding to the first light guiding side 14 is higher. Further, in such an embodiment, a light reflecting member (not shown) may be disposed on the side of the first light guiding side 14 away from the second light source 54, and the light reflecting surface of the light reflecting member faces the inside of the first light guiding side 14, so as to avoid mixing the light of the second light source 54 with other light, and improve the utilization efficiency of the light of the second light source 54.

The second light source 54 includes a plurality of second light emitting units 541, and the plurality of second light emitting units 541 are sequentially arranged at intervals along the extending direction of the corresponding first light guiding side 14.

In the present embodiment, the light source module 50 may further include a third light source 56, where the third light source 56 is configured to provide incident light to the second light guiding side 16, that is, the light of the third light source 56 is emitted through the second light guiding side 16 to form the light effect of the light emitting line. Because the second light guiding side 16 and the corresponding first light guiding side 14 are arranged around one light guiding plate 32, at this time, the luminous wire corresponding to the second light guiding side 16 and the corresponding first light guiding side 14 surrounds the luminous surface corresponding to the light guiding plate 32, so that the stereoscopic vision light effect with a relatively clear edge angle is formed.

The third light source 56 is disposed on the side of the substrate 51 facing away from the light guide plate 32, and is disposed at an edge portion of the substrate 51. The end of the second light guiding side 16 corresponding to the third light source 56 is exposed on the side of the substrate 51 facing away from the light guiding plate module 30, so that the light of the third light source 56 can enter and penetrate the second light guiding side 16 to exit. The number of the third light sources 56 may be the same as the number of the second light guiding sides 16, for example, the number of the third light sources 56 is plural, the plural third light sources 56 are disposed in one-to-one correspondence with the plural second light guiding sides 16, and the light of each third light source 56 is emitted to the external environment through the corresponding second light guiding side 16 to form a light emitting line.

In this embodiment, to improve the light utilization rate of the third light source 56, the second light guiding side 16 may be exposed on a side of the substrate 51 facing away from the light guiding plate 32, for example, an end surface of the second light guiding side 16 is flush with a surface of a side of the substrate 51 facing away from the light guiding plate 32, so that the light of the third light source 56 located on the side can be directly incident on the second light guiding side 16.

In other embodiments, the second light guiding side 16 may protrude from a side of the substrate 51 away from the light guiding plate module 30, so that a portion of the second light guiding side 16 and the third light source 56 may be disposed at a distance from each other, and the light of the corresponding third light source 56 may be directly incident to the second light guiding side 16. Further, in such an embodiment, a light reflecting member (not shown) may be disposed on the side of the second light guiding side 16 away from the third light source 56, and the light reflecting surface of the light reflecting member faces the inside of the second light guiding side 16, so as to avoid mixing the light of the third light source 56 with other light, and improve the utilization efficiency of the light of the third light source 56.

The third light source 56 includes a plurality of third light emitting units 561, and the plurality of third light emitting units 561 are sequentially arranged at intervals along the extending direction of the corresponding second light guiding side 16. The third light emitting unit 561 may be an LED light emitting unit, and its light emitting side is disposed toward the direction in which the second light guiding side 16 is located. Further, the third light emitting units 561 of the third light source 56 are arranged at the edge portion of the substrate 51, and the distance between the third light source 56 and the outer periphery of the substrate 51 is greater than the distance between the first light source 52 and the outer periphery of the substrate 51, i.e. the third light source 56 is relatively closer to the central portion of the substrate 51, so that the first light source 52 and the third light source 56 are staggered in the thickness direction, which can avoid light cross-talk and facilitate the layout of conductive traces on the substrate 51.
