By adopting the technical scheme, the technical scheme of the embedded luminous identification picture phase spreading device provided by the invention has the following positive effects:

it is known that light entering the interior of a transparent sheet (glass, plexiglas) from one end face (i.e. the first cross-section) and traveling in a direction parallel to the sheet surface (i.e. laterally) with high reflectivity will exit at the other end face (i.e. the second cross-section) of the sheet, while the sheet surface is substantially non-luminescent. It was found through experiments 1 that the light transmitted in the transparent plate is as if it were water running inside the plate, even in places and corners where the light from the light source cannot be directed straight, as long as the water can flow. By utilizing this phenomenon, it was found that light entering from the side end surface of the transparent plate was emitted not only from all the side end surfaces on the periphery of the plate material but also from the side end surfaces of the hollow patterns formed in the plate material. Experiments show that 2, on the premise that no light scattering part is arranged, the LED light source emitting light towards the first section is observed through the second section of the light guide plate, and the observed point-like light spots emitted by the LED are completely the same as the visual effect of directly observing the light emission of the LED light source (namely, the light guide plate is not used); however, if the light diffusion member of the transparent material is disposed on the second section of the light guide plate, the light emitted from the LED light source through the light guide plate on the light diffusion member is completely uniform and is emitted as a whole. And viewed by the light-dispersing piece, the side end surfaces emit light uniformly and LED light spots cannot be seen.

According to the disclosed optical principle, the technical scheme is applied to the light guide plate to form the hollow groove (namely the light-gathering groove), the groove wall of the light-gathering groove is ingeniously applied to be the second cross section, the light-gathering groove can internally play a total reflection role and externally play a stealth role, light emitted by the second cross section is directly projected onto the light-scattering member, the light-scattering member emits light in a whole body and projects the light-gathering groove into a space defined by the light-scattering member and the bottom plate, and light can be spread to each corner in the space through sufficient diffuse reflection in the light-gathering groove.

Firstly, a sinking space formed by a light scattering piece butted with the wall of a light collecting groove and a bottom plate provides conditions for the sufficient scattering of light, the sinking space has light gathering and light gathering effects to form a sinking light storing space, an LED light source arranged outside the light collecting groove emits light, the emitted point light (non-uniform light spots) is transmitted through high reflectivity in a light guide plate and is projected on the light scattering piece of the light scattering material, the light scattering pieces around the light collecting groove scatter uniform light to the space in the groove, the light scattering pieces around the light collecting groove are equivalent to a light transmission panel of a transversely arranged light box, the distance from the light source to the light scattering pieces is equivalent to the thickness of the light box, all the light scattering pieces emit light and are intensively projected in the space in the light collecting groove, and the defects of serious light spots, hard feeling of the light, no dispersion effect and non-uniform light when the LED light source directly (without a light transmission structure) emits light are effectively avoided by utilizing the light scattering piece with the uniform light and light scattering effects (because the, meanwhile, all the light scattering pieces are multiplexed into the light reflecting and light gathering side walls, so that light in the light gathering groove is fully scattered, all positions and any corners in the three-dimensional space in the groove can be spread by light rays and spread on the front surfaces of other works such as photos, patterns or embroidery arranged on the bottom plate of the light gathering groove.

Secondly, the light scattering piece made of the opal light-transmitting material is fixed on the wall of the light-gathering groove on the transparent light guide plate, and is just like being embedded on the transparent light guide plate, because the periphery of the light scattering piece is the transparent light guide plate and has a hidden visual effect, the light scattering piece has a suspension effect, and any redundant part except for the picture can not be seen in each direction near the light scattering piece, and the connection between an electric wire and a power supply can not be seen; when the power is lighted, the light guide phenomenon that the transparent light guide plate does not absorb light is utilized, the light guide plate still has the invisible effect, most of light is intensively scattered out through the inner side end face of the light scattering piece (the side end face butted with the second section on the light scattering piece is the outer side end face), and is projected into the light gathering groove, so that the brightness is brighter, the light emitting is more uniform, and the effect is better. Meanwhile, a small part of light is scattered out of the positive end face of the light scattering piece to display a contour light-emitting pattern of the light-gathering groove, and compared with a transparent light guide plate which still does not absorb light at the moment, the suspension effect of the light scattering piece is more obvious and more magic.

Meanwhile, the other non-luminous parts except the light-diffusing piece are compared with the sinking luminous space of the light-gathering groove, so that an obvious boundary line is formed between the sinking luminous space in the light-gathering groove and parts slightly dark around the light-gathering groove, and the light in the light-gathering groove is not diffused uniformly, so that the light-storing effect is achieved, the effect is particularly important for the visual effect of the painting works at the bottom of the tray, the painting works can show a planar two-dimensional visual effect, and the light-emitting effects of the space in the light-gathering groove and the painting works can have special stereoscopic impression and equivalent visual effect by matching with the whole three-dimensional space in the uniformly-diffused light-gathering groove, which cannot be achieved by the traditional painting works and a backlight device or a planar side light device; meanwhile, according to the area size of the picture works, the light spreading effect can be optimal by setting the height distance between the light-transmitting groove wall and the picture works at the groove bottom (the larger the distance is, the more uniform the light spreading effect is).

Finally, through the design of the shape of the light-focusing groove and the butt joint of the light-diffusing piece matched with the shape of the light-focusing groove, various light-focusing grooves matched with the painting works can be realized, such as a heart-shaped light-focusing groove, a circular light-focusing groove or a special-shaped light-focusing groove and the like, after the light-diffusing piece receives the light emitted by the second section, most of the light is projected into the groove, and meanwhile, the positive end surface of the light-diffusing piece also emits a small amount of light, so that the luminous outline pattern emitted by the positive end surface of the light-diffusing piece can be viewed while the painting works are viewed, the auxiliary decoration effect on the painting works and the decoration effect on the themes and ideas to be expressed by the painting works can be.
