Within a certain range, the depth of the sinking condensation space is in direct proportion to the evenness of the light spreading and in inverse proportion to the brightness of the light spreading.

3, the setting of light-shading spare makes the peripheral position that does not need to give out light or do not need direct light-emitting of light-concentrating groove uncovered or filtered, especially sets up the light-shading spare at light-concentrating groove notch eaves column structure, make the light-emitting terminal surface covered at longitudinal direction, the only strong luminous position in the light-concentrating groove is covered promptly, not only can gather together light downwards and can eliminate and reduce from the front and observe the interference of all unnecessary light to visual effect when sinking the bottom plate in the spotlight space, show the bandwagon effect on the bottom plate surface that is evenly spread by light in the spotlight space that sinks more prominently.

4, through the selection and the design to light-shading member structure, shape and material, the existence of light-shading member also can assist and set off with the light spreading effect of sinking in the spotlight space for the show position of priority, realizes more ornamental effect.

When paving light to the bottom plate surface, light produces the illumination effect to the space outside the positive notch of spotlight groove through abundant scattering and reflection back in sinking spotlight space, plays the dual function of show artistic effect and illumination.

In the above structure (except the structure shown in fig. 2A), the bottom plate 5 is directly connected to the bottom of the light-gathering groove body at the periphery of the opening at the back of the light-gathering groove 2.

The light-exiting end surface 15 is configured as a smooth plane (but not limited to a smooth plane), and optionally, the light-exiting end surface 15 is configured as a non-smooth surface, such as a concave-convex structure (including a frosted surface) with a surface provided with grains or grooves, so as to increase a special light-exiting projection effect. The shading piece 11 covers the whole area from the edge of the front notch of the light-gathering groove 2 to the picture frame body 7. Alternatively, the light shield 11 may be a film or coating for the corresponding effect.

In addition, in fig. 3A, bottom plate 5 and the setting of the works of painting 6 are in 2 back notches below of light gathering tank, bottom plate 5 can be wall or ceiling or other ready-made object surfaces, and it has the spacer 12 to add the pad between bottom plate 5 and the light gathering tank body 3 to increase the distance between bottom plate 5 and the 2 bottom notches of light gathering tank, thereby increase the degree of depth of the spotlight space that sinks, guarantee to set up the shop light quality on the 6 surfaces of the works of painting on bottom plate 5 surface. Experiments prove that in order to ensure the light spreading quality, the larger the area of the painting works 6 (namely, the larger the area needing light spreading), the depth of the sinking light-gathering space should be correspondingly deepened, namely, within a certain range, the light spreading uniformity of the painting works 6 is in direct proportion to the depth of the sinking light-gathering space.

At this time, the bottom plate 5 of the depressed structure together with the plate-shaped spacer 12 can be regarded as a bottom plate, i.e., the bottom plate is composed of the plate-shaped spacer 12 together with the bottom plate 5 of the depressed structure, similar to the bottom plate 5 shown in fig. 3C; in addition, the light-shielding member in the structure is composed of a light-shielding member 11 made of a light-transmitting material and positioned on the top of the light-emitting end surface 15, a light-shielding member 11 made of a non-light-transmitting material and arranged on the periphery of the light-shielding member 11, and the light-shielding member 11 made of the light-transmitting material and positioned on the top of the light-emitting end surface 15 can set off the light spreading effect in the sinking light-condensing space through a corresponding light-transmitting effect (namely, a light-transmitting pattern with a rectangular; and finally, the picture frame further comprises a transparent protective layer 10, wherein the transparent protective layer 10 is made of transparent materials, the peripheral outer edge of the transparent protective layer is arranged in the picture frame body 7 and covers the periphery of the light gathering groove 2 and the whole area of the front notch of the light gathering groove 2, and the light shading piece 11 is included.

When the light source 1 emits light, a small part of light transversely transmitted in the light gathering groove body 3 can penetrate through the surface of the light gathering groove body 3 between the light shading piece 11 and the picture frame body 7 and between the light shading piece 11 and the edge of the front notch of the light gathering groove 2 to be scattered out, and the light spreading effect in the sinking light gathering space is supported.

Therefore, the light projected by the non-transparent light-transmitting material light-gathering tank body 4 is softer, and the laying effect of the surface of the bottom plate 5 is improved. In addition, the non-light-transmitting shading piece 11 does not cover the light-gathering groove body 4, and the exposed light-gathering groove body 4 can display a rectangular outline luminous pattern matched with the light-gathering groove 2 when viewed from the front; meanwhile, the light shading part 11 is provided with a hollowed light transmission groove 16 with a corresponding pattern besides the hollowed area corresponding to the light gathering groove 2, and a small number of light rays scattered on the surface of the light gathering groove body 3 are displayed through the hollowed light transmission groove 16 and are used for matching and setback the light spreading effect in the sinking light gathering space.

Optionally, the non-hollow light-gathering groove 2 may be arranged on the front side of the light-gathering groove body 3, that is, the opening is upward, and the bottom plate 5 may be arranged on the groove bottom (equivalent to the back opening) or on the position corresponding to the light-gathering groove 2 below the light-gathering groove body 3.

Further, as shown in fig. 3G, the structure shown in fig. 1E and the above structure are mainly different in that the light-emitting end surface 15 is concave, so as to realize a special laying effect. Alternatively, the shape of the light-exiting end surface 15 may be a convex curved surface similar to the light-collecting groove body 3 in fig. 1E.

Further, as shown in fig. 3H, the main difference from fig. 3D is that the front frame eaves 13 of the picture frame 7 serves as a light shielding member, that is, the front frame eaves 13 of the picture frame 7 and the light shielding member are integrated, and the exposed portion of the light collecting groove body 3 (i.e., the portion between the edge of the front opening of the light collecting groove 2 and the front frame eaves 13 of the picture frame 7) can display a rectangular outline light emitting pattern, and plays a role in assisting to support the light emitting effect; in addition, the surface of the bottom plate 5 (i.e., the surface of the depressed portion) located within the area of projection in the longitudinal direction of the light-condensing groove 2 is located below the bottom of the groove of the light-condensing groove 2.

Further, as shown in fig. 3I, the main difference from the structure shown in fig. 3A is that the transparent light guide structure transversely disposed is a non-flat transparent light guide, specifically, a light-gathering tank body 3 of a non-flat transparent zigzag plate-shaped light guide structure, and the zigzag plate serving as the light-gathering tank body 3 is customized and processed or formed by hot bending through a corresponding mold under the condition that light can be transmitted with high reflectivity in the light-gathering tank body; compared with the structure shown in fig. 3A, the special shape structure of the light-gathering groove body 3 shown in fig. 3I greatly increases the height distance between the light-emitting end face 15 and the bottom plate 5, and the light-gathering space is deeper, meanwhile, the light-emitting end face 15 faces to the downward direction, namely, the light-emitting end face 15 is a non-vertical inclined plane, and the light-spreading and emitting effect projected from the light-emitting end face 15 is more concentrated. Meanwhile, a coating or a film with a light shielding effect is coated on the front surface of the light-gathering groove body 3 of the transparent zigzag plate-shaped light guide structure to form a light shielding piece 11.

Further, as shown in fig. 4A, the light-gathering groove 3 is a longitudinally-arranged transparent light-guiding structure, and specifically includes a longitudinally-arranged transparent light-guiding plate (i.e., the light-gathering groove 3) and a light-scattering structure and a light-reflecting layer 9 arranged on the surface of the light-emitting end face 15 opposite to the light-emitting end face on the light-gathering groove 3. An installation groove 8 for placing the light source 1 is formed in the position, close to the upper end, of the light-gathering groove body 3, and the light source 1 is placed in the installation groove 8 and emits light downwards longitudinally; the light gathering groove body 3 is fixed in a picture frame body 7 made of a section bar with a C-shaped cross section, and a reflecting layer 9 is arranged between the side end face, provided with the light scattering structure, of the light gathering groove body 3 and the inner side wall of the picture frame body. The astigmatism structure is the sculpture score line or pattern, and the astigmatism structure helps making the light of vertical transmission in spotlight cell body 3 can transversely shine light-emitting terminal surface 15 and project in spotlight groove 2 through the scattering effect of astigmatism structure. The reflecting layer 9 is used for ensuring that light rays longitudinally transmitted in the light-gathering groove body 3 can be reflected to the light-emitting end face 15 more when the light rays are scattered out through the light-scattering structure. The light source 1 emits light, enters the light gathering groove body 3 through the end face of the inner side wall of the mounting groove 8, is longitudinally transmitted, transversely emits light from the light emitting end face 15 through the scattering effect of the light scattering structure (namely the light source 1 is in butt joint with the light emitting end face 15), and projects the light into the sinking light gathering space. Different from the structure shown in fig. 3A, in this structure, the light longitudinally enters the light-gathering groove body 3 and is not directly transmitted to the light-emitting end face 15, but is indirectly and transversely transmitted to the light-emitting end face 15 through the scattering effect of the light scattering structure and the reflection effect of the reflective layer 9 and is projected out. The structure is suitable for spreading light of large-area painting works, and the height of the light-emitting end face 15 and the depth of the sinking light-gathering space are flexibly set. Optionally, the mounting groove 8 for the built-in light source 1 may be disposed near the lower end of the light-gathering groove body 3, and the light source 1 emits light upwards and longitudinally.

In this structure, the picture frame body 7 may be made of a material having a heat dissipation function, such as an aluminum profile, and the light source 1 may be fixed to the inner bottom surface of the picture frame body, thereby ensuring stable operation of the light source 1. Meanwhile, the light rays emitted transversely are scattered by the light-gathering groove body 4, so that the light ray quality is higher. Optionally, the light source 1 may also be disposed between the upper end surface of the light-gathering tank 3 and the inner top surface of the picture frame 7, and emits light longitudinally downward.

Further, as shown in fig. 4C, unlike the structure shown in fig. 4B, the light diffuser 4 is in non-contact butt joint with the side end surface of the longitudinal transparent light guide plate 3, and a distance is provided between the light diffuser and the longitudinal transparent light guide plate, so that the light emitting effect of the light emitting end surface 15 is more uniform, and the light spreading quality is better.

In the above embodiment, the picture frame 7 and the light-gathering tank are not integrated into a single structure.

Further, as shown in fig. 5A, different from the above structure, the picture frame body 7 and the light-gathering groove body are of an integral structure, and are made of a light-transmitting material through corresponding die customization and processing, and the outer surface of the integral structure except the light-emitting end face 15 is coated with a coating serving as a light-shielding member 11, so as to ensure that only the light-emitting end face 15 projects light outwards and transversely. And a reflecting layer can be coated on the corresponding inner wall surface in the integrated structure, so that more light rays can be projected from the light-emitting end face 15. The structure is convenient to assemble and saves cost.

Alternatively, as shown in fig. 5C, the structure is different from that shown in fig. 5B in that the light emitting direction of the light source 1 does not directly face the light-emitting end face 15 transversely, but emits light longitudinally and upwardly, indirectly irradiates the light-emitting end face 15 through reflection of the inner wall inside the integral structure, and projects the light-emitting end face 15 into the sinking light-condensing space.

Alternatively, in the structure shown in fig. 5A, the picture frame and the bottom plate may be processed into an integral structure, and the light-gathering tank body may be a separate structure.

Optionally, the LED strip light sources 17 are respectively disposed and fixed on the inner side walls of the groove on both sides of the groove structure 20 along the extending direction of the inner wall of the groove, and the light sources 17 fixed on the two side walls emit light in opposite lateral directions and both face the space in the groove; or the LED strip light source 17 is arranged along the extending direction of the groove structure 20 and fixed at the bottom of the groove structure 20, and emits light upwards to directly irradiate the light-transmitting member 19 arranged at the groove, as shown in fig. 6D, in such a way that the LED strip light source 17 emits light upwards. When the light source 1 and the light source 17 emit light, the forward light-emitting pattern in the shape of 'A' on the bottom plate 5 can be seen through the front observation, the whole sinking light-gathering space is filled with three-dimensional light, so that the surface of the bottom plate 5 at the periphery of the forward light-emitting pattern in the shape of 'A' at the bottom of the sinking light-gathering space can be projected and clearly observed by the light-emitting end face 15, the defect that the non-light-emitting area at the periphery of the forward light-emitting pattern is dark and inconvenient to observe due to the high brightness of the forward light-emitting pattern of the light-transmitting piece 19 in the prior art is solved, and the whole effect of the forward light-emitting pattern can be matched and assisted to be improved through the visual effect design of the material.
