and the notch of the light guide plate, which is internally provided with a light source, is arranged and butted with the longitudinal light emitting part.

Wherein, the light scattering piece is transparent or non-transparent light-transmitting material.

Further, the longitudinal light emitting piece is made of a light-transmitting material; or,

the longitudinal light emitting piece is made of transparent material; or,

the longitudinal light emitting piece is a combined structure of a transparent material and a light-transmitting material.

Further, the light guide plate is of a planar structure; or,

the light guide plate is of a curved surface structure.

The light guide plate further comprises a surface decoration layer, at least one surface of the light guide plate is covered with the surface decoration layer, hollow grooves corresponding to the light scattering traces are formed in the surface decoration layer, and the light outlet piece is in butt joint with the light scattering traces through the hollow grooves; or,

By adopting the technical scheme, the technical scheme of the invisible three-dimensional luminous mark provided by the invention has the following positive effects:

through test tests, after the light emitting piece is covered on the light scattering trace of the same light source, the light guide plate and the light scattering trace on the light guide plate, the light emitting intensity of the light emitting piece is more than 2 times of the light emitting intensity of the light scattering trace before the light emitting piece is not covered. The scheme positively utilizes the test result.

2, the structure of the groove or the nick on the light guide plate is equivalent to the box body of the traditional luminous mark, the depth of the groove or the nick is equivalent to the thickness of the box body of the light box, and because the light of the light source is transversely transmitted in the light guide plate, the light source is not required to be arranged in the groove or the nick, the light emitting piece butted with the groove or the nick can uniformly emit light no matter the depth of the groove or the nick, and because no light source is arranged in the light guide plate, any narrow and small-sized luminous pattern can be realized, which is incomparable to the traditional luminous mark. The scheme also actively utilizes the phenomenon and combines the test results, breaks through the structural barrier of the traditional luminous mark, and can be applied to more luminous marks with high requirements, high standards, delicacy and small size.

In the luminous mark, by utilizing the light guide principle of a transparent material and utilizing the corresponding light scattering traces arranged on the light guide plate to fold light transversely transmitted by the light scattering traces to 90 degrees and then scatter the light perpendicular to the plate surface, and then by utilizing the light emitting piece with good light absorption and light transmission characteristics, the light longitudinally scattered by the light scattering traces is concentrated on the light emitting piece to be displayed, so that the defect of insufficient light emission caused by poor light absorption characteristics of the traditional transparent plate and the light scattering traces is overcome; because the light sources are intensively arranged at the periphery of the light guide plate, the number of the light sources can be more or less, the number of the light sources is related to the luminous intensity of the light emitting parts, the light sources indirectly polish all the light emitting parts through the light scattering marks, and all the light longitudinally scattered through the light scattering marks is uniform light without light spots. The luminous sign light source that has improved traditional lamp house structure can only depend on the application defect in the box, leads to the light source quantity big, and the box is heavy, and processing is loaded down with trivial details.

The U-shaped notch groove with the corresponding shape can be designed as required, the LED light source is directly placed in the notch groove, and light emitted by the light source enters the light guide plate through the groove side wall section in the U-shaped notch groove. And then, the light emitting pieces with corresponding shapes are butted at the notches of the U-shaped notches, so that the light guide plate not only perfectly integrates the light source into the light guide plate to form an integral structure, but also the notches can be used as a light source carrier and simultaneously the light emitting pieces butted with the notches of the light guide plate can be used as a part of a light emitting pattern. The traditional transparent plate luminous mark with the carved patterns needs to be separately provided with a U-shaped clamping groove component internally provided with a light source, the transparent plate with the carved patterns is embedded into a clamping groove of the component, and light of the light source in the clamping groove component can enter the transparent plate. Compared with the traditional identification of the structure, the structure of the technical scheme is more concise and reasonable, and the cost is lower.

The light emitting part can be made into light emitting parts with certain thickness, height or different light transmittance and light transmission colors according to the effect requirement, for example, the light emitting part made of transparent material with certain thickness or the light emitting part formed by combining the transparent material and the transparent material with certain thickness, thus, the light emitting parts in various forms do not need the light scattering traces for connecting the light emitting parts on the light guide plate, and the whole luminous mark can not only realize different brightness and light colors of the corresponding parts of the luminous pattern in vision, but also reflect stereoscopic impression and layered impression and make the luminous mark with higher artistic effect.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

As shown in fig. 1A and 1B, the light emitting sign provided by the present embodiment includes: a light source 1, a transverse light guide plate 2, a longitudinal light emitting member 3 and a grooved light scattering mark 5 (including U-shaped grooves or/and scores).

The light source 1 is a banded LED light source formed by a plurality of LEDs welded on the flexible circuit board, the inside of the transverse light guide plate 2 is made of transparent materials and is a light guide plate with a plane structure, and the surface can be a smooth surface or a frosted surface or a film-coated surface. Carving a groove light scattering trace 5 pattern with a certain depth on a transverse light guide plate 2, wherein the groove light scattering trace 5 with a deeper cross section is carved on the periphery (at the moment, the extending shape of the groove light scattering trace 5 is a rectangular ring) and a groove light scattering trace 5 pattern with a shallower middle part is carved on the periphery, then placing a strip-shaped LED light source 1 in the U-shaped groove light scattering trace 5 with the deeper periphery, arranging the strip-shaped LED light source in the groove 5 along the longitudinal extending direction of the groove side wall section, enabling the light emitting direction of the light source 1 to face the inside of the light guide plate 2 and other groove light scattering trace 5 patterns with the shallower depth, enabling the light emitted by the light source 1 to enter the inside of the light guide plate through the butted groove side wall section, realizing the butt joint of the light source 1 and the light guide plate 2, and enabling the light source 1 to. Then, a plurality of light emitting pieces 3 matched with the shapes of the light scattering marks 5 of each groove are manufactured, the light emitting pieces 3 are made of light-transmitting materials, and the light emitting pieces 3 are formed by milling and carving the plates made of the materials according to design patterns through numerical control equipment; or the light emitting component 3 is formed by heating hard strip-shaped light-transmitting adhesive tapes with corresponding shapes and materials, bending the adhesive tapes according to the shapes of the design patterns, and cooling and shaping the adhesive tapes; or the light emitting component 3 is made of flexible strip-shaped light-transmitting adhesive tapes with corresponding shapes and materials by a process of directly bending and fixing and molding according to a design pattern. Wherein, the butt joint mode of the light-emitting piece 3 and the grooved light scattering trace 5 is as follows: the rectangular ring-shaped light-emitting member 3 corresponding to the deeper-grooved light-scattering marks 5 was covered over the opening of the deeper U-grooved light-scattering marks 5 from the front. The projection of the light-emitting members 3 onto the engraved grooves 5 (i.e. light scattering marks) covers the area of the notches of the engraved grooves 5 (the coverage is included in the intersection category), and then one end of the other light-emitting members 3 is covered from the front over the front opening of the corresponding light scattering marks 5 of the shallower engraved grooves. Thus, a part of the light emitted from the light source 1 is transmitted from the inside to the shallower light scattering traces 5 through the cross section of the transverse light guide plate 2 (i.e., the inner side wall of the deeper U-shaped groove 5), and is longitudinally projected onto the corresponding longitudinal light-emitting member 3 through the shallower grooved light scattering traces 5, so that the longitudinal light-emitting member 3 emits light, and the longitudinal light-emitting member 3 receives the longitudinal light projected from the grooved light scattering traces 5; the other part of the light emitted by the light source 1 is reflected and scattered by the side wall and the bottom surface inside the light scattering trace 5 with the deeper U-shaped groove, so that the rectangular annular light emitting piece 3 covered on the light scattering trace 5 with the U-shaped groove emits light. Therefore, in vision, the whole transverse light guide plate 2 emits light except the light emitting piece 3, other parts have invisible effects (the light source cannot be seen to emit light at the same time), longitudinal light emission of a deeper groove can be realized in the placement mode of the light source 1, the light scattering marks 5 of the deeper groove play a dual role, the light source 1 can be placed, the light emitting piece 3 at the groove opening can emit light, and the whole light emitting identification structure is very clean, light and handy and thin.

Optionally, a reflective layer may be disposed on the bottom surface of the notch 5 for placing the light source 1, so as to increase the light intensity of the notch 5, and increase the light intensity of the rectangular ring-shaped light emitting element 3 covered on the notch.

Optionally, as shown in fig. 1C, in the deeper notch 5 with the light source 1 inside, a light scattering member 11 is additionally arranged between the light source 1 and the side wall section of the notch 5 facing the light source 1, the light scattering member 11 is made of a transparent material, and the light scattering member 11 reinforces the light source 1 to prevent the light source from being separated from the side wall where the light source is located due to heat generation, and at this time, the light source 1 is also arranged near the section. Preferably, the bottom of the light diffuser 11 is provided with a notch or a reflective layer, and the light diffuser 11 reinforces the light source 1 and increases the luminous intensity of the rectangular ring-shaped light emitting member 3 covered on the notch of the notch 5.

Example 2

As shown in fig. 2A and fig. 2B, the light emitting indicator provided in the present embodiment includes: the light source comprises a light source 1 (a strip-shaped LED light source fixed on a light source fixing frame 7), a transverse light guide plate 2, a longitudinal light emitting piece 3, a grooved light scattering trace 5 and a light source accessory (namely the light source fixing frame 7).

Unlike embodiment 1, in this embodiment, the light source 1 is a strip-shaped LED light source fixed on the light source fixing frame 7, and the light source fixing frame 7 is disposed near the periphery of the light guide plate 2. The LED lamp beads are welded on the flexible circuit board 9, the strip-shaped LED light source is stuck and fixed on a fixing frame 7 outside the transverse light guide plate 2, the fixing frame 7 surrounds the light guide plate 2, the LED light source 1 fixed on the fixing frame 7 is opposite to the cross section of the side end face at the periphery of the light guide plate 2, the light source 1 is in butt joint with the cross section of the light guide plate 2, namely the strip-shaped LED light source is arranged on a light source accessory along the longitudinal extension direction of the cross section of the side end face at the periphery of the transverse light guide plate, and light of the light source. The butt joint mode between the longitudinal light emitting piece 3 and the engraved light scattering marks 5 on the light guide plate 2 is as follows: the longitudinal light-emitting member 3 is sealed over the engraved light scattering mark 5 from the front surface (engraved opening surface) of the engraved light scattering mark 5, and is butted against the front surface of the engraved light scattering mark 5. Therefore, the light of the light source 1 enters the light guide plate 2 from the cross section of the side end face of the periphery of the light guide plate 2, when passing through the engraved light scattering mark 5, because the engraved light scattering mark 5 with a certain depth is similar to a small box body, when the light irradiates the engraved light scattering mark 5, the engraved light scattering mark 5 is equivalent to a small light-emitting box body (the height of the box body is the engraved depth), and the light is projected on the longitudinal light-emitting piece 3 covered on the light-emitting box body.

Example 3

As shown in fig. 3A, the light emitting indicator provided in this embodiment includes: a light source 1, a transverse light guide plate 2, a longitudinal light emitting member 3 and a grooved light scattering trace 5, and a reflecting layer 6 (belonging to a kind of light scattering trace).

The difference between this embodiment and embodiment 2 is that in this embodiment, the longitudinal light-emitting member 3 is butted against the engraved light scattering marks 5 on the light guide plate 2 from the back side of the engraved light scattering marks 5 (the opposite side of the opening of the engraved groove on the light guide plate 2), that is, the light-emitting member 3 is butted against the back side of the engraved light scattering marks 5 at a corresponding position and is adhered and fixed on the surface of the light guide plate 2. In order to increase the luminous efficiency, the inner surface of the engraved groove 5 may be covered or padded with a reflective layer 6 (reflective/light-enhancing coating or padded reflective/light-enhancing material) as required, as shown in fig. 3B, so as to increase the luminous effect of the longitudinal light-emitting member 3.

Fig. 3B is a schematic structural view of fig. 3A, in which the strip-shaped LED light source fixed on the fixing frame 7 is directly disposed on the cross section of the peripheral side end surface of the light guide plate, and the light source 1 is directly disposed on the cross section to realize the butt joint of the light source and the cross section of the light guide plate 2, that is, the strip-shaped LED light source is disposed on the cross section along the longitudinal extension direction of the cross section of the peripheral side end surface of the transverse light guide plate, and the light of the light source enters the light guide plate.

Alternatively, as shown in fig. 3C, unlike the structure of the embodiment shown in fig. 3A, a matching notched light diffusion mark 5 is also provided at a position corresponding to a notched light diffusion mark 5 provided at the back surface of the light guide plate 2 on the front surface of the light guide plate 2, so that light diffusion marks are provided at corresponding positions on both the front surface and the back surface of the light guide plate 2, and each of the longitudinal light-emitting members 3 is simultaneously butted with two light diffusion marks corresponding to the front surface and the back surface of the light guide plate 2. Thus, each light-emitting member 3 is projected by the longitudinal light scattered by the two butted grooved light scattering marks 5, so that the light-emitting brightness of the light-emitting member 3 is higher. Furthermore, a reflecting layer 6 is covered or padded on the inner surface of the engraved groove 5 on the reverse side of the light guide plate 2, so that the light emitting intensity of the light emitting element 3 is further improved.

Example 4

As shown in fig. 4A and 4B, the light emitting indicator provided in the present embodiment includes: the light source 1 (a strip-shaped LED light source placed in the U-shaped clamping groove 8), the transverse light guide plate 2, the longitudinal light emitting piece, the grooved light scattering traces 5 and the light source accessories (namely the U-shaped clamping groove 8).

In the embodiment shown in fig. 4A, the light source 1 is a strip-shaped LED light source disposed in the U-shaped clamping groove 8. The strip-shaped LED light source is placed in the U-shaped clamping groove 8, and the light emitting direction of the strip-shaped LED light source faces to the opening of the clamping groove 8. Then, the section of one end face of the transverse light guide plate 2 is inserted into an opening with a built-in LED light source U-shaped clamping groove 8 (at this time, the U-shaped clamping groove 8 is arranged near the periphery of the light guide plate), so that the LED in the clamping groove 8 is opposite to the section of the light guide plate 2, and the light source is butted with the section. In addition, one of the two notched light scattering traces 5 on the light guide plate 8 is not butted with the light emitting member 3, so that when the light of the light source 1 passes through the two notched light scattering traces 5, the light emitting member 3 and the notched light emitting member which is not butted with the light emitting member emit light with different intensities, thereby realizing the visual effect that the same light guide plate 2 can emit light patterns with different brightness.

In this embodiment, in fig. 4B, the light guide plate 2 in fig. 4A is replaced with a light guide plate 2 (belonging to a curved surface structure) having a bent shape, and other implementation steps are the same as those in the embodiment in fig. 4A, so that light emitted by the LED light sources 1 in the clamping grooves 8 is transmitted in the light guide plate 2 with high reflectivity along the bending extension direction of the light guide plate 2, and is emitted longitudinally through the light scattering marks 5 and the light emitting members 3.

Example 5

As shown in fig. 5A, the light emitting indicator provided in this embodiment includes: the light source 1, the horizontal light guide plate 2, the vertical light emitting piece 3 and the light emitting piece 4, and the groove light scattering trace 5; fig. 5B, 5C, 5D and 5E show the addition of a top-coat layer 10 to fig. 5A.

The difference between this embodiment and embodiment 1 is that, in this embodiment, the light-emitting member 4 is made of a transparent material, and the light-emitting member 4 made of the transparent material can enable the light longitudinally projected from the grooved light-scattering marks 5 butted thereto to continue to be vertically transmitted upwards along the light-emitting member 4 and to be projected from the top end surface of the light-emitting member 4, and the effect is that the top end surface emits light, rather than emitting light as a whole, and the light-emitting effect of the light-emitting member 4 is different from that of the light-emitting member 3. Therefore, the height of the light emitting piece 4 can be set randomly according to needs, so that in the whole light emitting mark, different parts of the light emitting patterns emit light at different heights, the light emitting effect is diversified, and the effect of multi-level light emitting in the longitudinal direction is realized.

Fig. 5B shows that a plate-shaped surface finishing layer 10 is padded on the surface of the light guide plate of fig. 5A on which the light emitting elements 3 and 4 are arranged, and the surface finishing layer 10 can also be a coating (including printing) or a film. The surface decoration layer 10 is provided with a hollow groove, the light emitting pieces 3 and 4 are butted on the front surface of the engraved groove 5 and cover the opening of the engraved groove 5 through the butt joint of the hollow groove arranged on the surface decoration layer 10 and the engraved groove light scattering trace 5 on the light guide plate 2, and the butt joint belongs to contact butt joint at the moment. The surface finish 10 serves to assist in illuminating the light elements 3 and 4 to achieve a particular lighting effect.

Fig. 5C shows that the plate-shaped surface decoration layer 10 is provided with hollowed-out grooves corresponding to the engraved light scattering traces 5 on the light guide plate 2, and the light emitting members 3 and 4 are covered on the corresponding engraved light scattering traces 5 by covering the corresponding hollowed-out groove openings on the surface decoration layer 10 and are in front butt joint with the engraved light scattering traces 5 on the light guide plate 2, wherein the butt joint at this time belongs to non-contact butt joint. The surface finish 10 serves to assist in illuminating the light elements 3 and 4 to achieve a particular lighting effect.

Fig. 5E shows that the plate-like surface-modifying layer 10 is made of a transparent material and is provided to protect the surface of the light guide plate 2. All the light emitting pieces 3 are adhered and fixed on a plate-shaped surface decoration layer 10 made of transparent materials, and are butted with the front surfaces of the corresponding grooved light scattering marks 5 through the surface decoration layer 10 with a pad arranged in the middle, and the butting is non-contact butting.

Fig. 5D is different from the embodiment of fig. 5C in that a surface decoration layer 10, a hollow groove and a light emitting member 3 are also disposed on the back surface of the light guide plate 2, the surface decoration layers 10 on both surfaces cover the light source 1 and the U-shaped groove 5 where the light source 1 is located, and the surface decoration layer 10 is a non-light-transmitting plate-shaped material, thereby realizing double-sided light emission.

Example 6
