Description

Technical Field

[0001] The utility model relates to the fields of games, toys and intelligent lighting, in particular to a touch light-guiding display panel. Background Art

[0002] Smart interactive luminous products are games, toys or lighting products that display interesting effects through human-computer interaction. Half of the existing lighting products use a front projection layout, that is, the light is irradiated forward to the lampshade with a pattern drawn on it to display the desired pattern. However, the front projection lighting has the disadvantages of being thick and having limited application scenarios. In addition, the existing luminous products on the market generally lack human-computer interaction and have a single usage scenario. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a touch light guide display panel, which can be used in multiple scenes, can realize multiple assembly combinations, and has multiple control methods, thereby improving the fun and practicality of the product.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a touch light-guiding display panel, comprising a transparent light diffusion area portion, a reflective portion arranged on the front or back side of the smooth light diffusion area portion, and an incident portion arranged on the side of the light diffusion area; the incident portion is used to inject light from a light source into the light diffusion area portion, and the light diffusion area portion is used to propagate visible light emitted from the incident portion, so that the visible light is irradiated to the reflective portion, thereby causing the reflective portion to reflect the light and shine.

[0005] Furthermore, the reflective portion is a reflective layer that completely or partially covers the light diffusion area or a reflective pattern that is physically carved on the light diffusion area. The reflective pattern is a frosted, rough carved groove pattern or a convex rib pattern. When the reflective portion completely or partially covers the light diffusion area, when light is irradiated to the reflective layer, the reflective layer can be seen to be shiny as a whole from the front or back of the reflective layer. The partial coverage can specifically be pasting patterns, printing patterns, etc., and the reflective pattern also has the same effect.

[0006] Furthermore, the reflective portion is a reflective portion with a frosted surface or a reflective portion with a translucent texture.

[0007] Furthermore, the reflective layer is any one of an ink printing layer and a sticker layer.

[0008] Furthermore, the light-reflecting portion is a light-proof layer, and the light-proof layer partially covers the light-diffusing region, so that the incident light is reflected and shines after being irradiated by the light-proof layer. Specifically, the incident light can be irradiated to a side of the light-proof layer close to the light-diffusing region to make it shine; or irradiated to a side of the light-proof layer to make it shine.

[0009] Furthermore, the reflective portion is a conductive layer, and the conductive layer is used to be electrically connected to the control board to form a touch control circuit.

[0010] Furthermore, the conductive layer is a conductive ink printing layer or a metal foil layer.

[0011] Furthermore, the incident part is at least one of a flat mirror, a convex lens, and a concave lens;

[0012] or,

[0013] The incident portion and the light diffusion region are integrally formed, and a surface of the incident portion close to the light source is at least one of a flat surface, a convex surface, and a concave surface structure.

[0014] Furthermore, the light diffusion region is made of soft material or hard material.

[0015] Furthermore, the soft material is silicone and the hard material is acrylic.

[0016] The beneficial effects of the utility model are as follows: a conductive layer is arranged on the reflective part, and the conductive layer is electrically connected to the touch control module of the control chip, so that the conductive layer on the reflective part forms a touch sensing point, and the area of ​​the conductive layer is directly proportional to the touch sensitivity; when the human body touches the area near the conductive layer, the touch control module of the control chip detects the change in capacitive reactance as the main control chip to control the light emission or control instructions, thereby adding a new control method and improving the interest and practicality of the product.

[0023] In the specification, references to "one embodiment," "an embodiment," or "some embodiments" mean that a particular feature, structure, or element described with reference to the embodiment is included in at least one embodiment of the subject matter being described. Thus, the phrases "in one embodiment," "in an embodiment," or "in some embodiments" in the specification do not necessarily refer to the same embodiment or embodiments. The particular features, structures, or elements may be further combined in any embodiment in a suitable manner.

[0024] In an embodiment, Figure 1 and 4 As shown, the utility model is a touch light guide display panel, which can be used as a luminous interactive lighting, for example, it can be applied in the field of luminescence, such as lighting, toys, and other decorative lamps.

[0025] The utility model is a touch light guide display panel, comprising a body composed of a light diffusion region 1, an incident portion 2, and a reflective portion 5. The light emitting portion 5 is arranged on the surface of the light diffusion region 1. The light diffusion region 1 is configured to transmit visible light emitted from the incident portion 2, and project light from the side of the light diffusion region 1 in a lateral projection manner, so that the reflective portion 5 on the light diffusion region 1 is illuminated. The light diffusion region 1 is made of a transparent material, and the front and back surfaces are smooth. Specifically, the surface of the area not covered by the reflective portion (the portion not covered by the reflective portion) is smooth. The smooth surface setting, like the principle of optical fiber, can make the incident light continuously reflected inside it, so that the light is efficiently transmitted; in this embodiment, the reflective portion 5 is in a non-transparent state, and can be a completely opaque state, made of metal foil, or can be a semi-transparent or semi-transparent state, for example, a layered structure is formed by printing with ink, or a surface frosted pattern is formed by engraving on the light diffusion region to achieve a reflective effect.

[0026] The working principle of this embodiment is that the light source 21, such as an LED lamp bead, emits light and emits the light from the incident part 2 into the light diffusion area part 1 for propagation. When the light propagates and irradiates the reflective part 5, when the reflective part 5 is an opaque layer, its edge can reflect the light to achieve edge glow, and the side of the reflective part 5 close to the light diffusion area part can also glow; when it is frosted or translucent, since the light can partially penetrate the material, the reflective part 5 can glow and reflect the light in different directions at the same time, so that the reflective part 5 can be seen glowing from all angles.

[0027] This way of irradiating light from the side transfers the projection distance from the front to the side compared to the original front projection, thereby optimizing the overall thickness of the main body. At the same time, since the reflective portion 5 can be designed to be hollow, a variety of patterns can be formed, providing rich effects.

[0028] It should be noted that a light board 200 a with a light source 21 is provided on one side of the incident portion 2 .

[0029] The light diffusion area is made of a transparent material, such as acrylic or transparent silicone.

[0030] Generally speaking, the display pattern layer, that is, the reflective portion 5, is any one of physically depicted patterns, ink printing (if it is conductive ink printing, it is a conductive ink layer 400), and a sticker. Of course, this is just to provide an optional method and is not a further limitation on the display pattern layer.

[0031] In another embodiment, the reflective portion 5 is an aluminum foil partially covering and fixed to the light diffusion area 1. The preferred aluminum foil is a hollow aluminum foil. After the incident light is reflected by the aluminum foil, it is emitted from the edge of the aluminum foil, forming a new visual effect by the reflection of the aluminum foil.

[0032] In the two embodiments, the reflective portion 5 is a conductive layer, and the conductive layer extends to the gold finger of the lamp board 200a in the incident portion to form a touch circuit. In other words, the incident light is extinguished or lit by touching the reflective portion 5. The specific conductive layer can be a metal foil or printed with conductive ink.

[0033] The display pattern layer displayed in the light diffusion region is a pigment coating or a trace formed by depicting (carving) on ​​the light diffusion region.

[0034] The above-mentioned ink printing can be printed with conductive ink. The conductive ink layer 400 is a layered structure and is electrically connected to the gold finger on the lamp board 200a. After power is turned on, when the fingertip touches the reflective part 5, its capacitive reactance changes and is detected and sent to the processor. The processor controls the lighting according to a preset program, and can achieve a variety of display effects, such as turning on and off the decorative lights or changing the color of the lighting.

[0035] In addition, after using the coating of the conductive ink layer 400, the reflection is more uniform and soft, taking into account the conductive performance of the coating, so that the hardware cost of the product design is lower.

[0036] like Figure 1-3As shown, it should be noted that the incident light is incident into the light diffusion area 1 through the lens in the incident part 2, and the surface of the lens through which the light path passes is a concave surface, a convex surface or a plane. Specifically, the incident part 2 is at least one of a flat mirror 2b, a concave lens 2c, and a convex lens 2d; or, the incident part and the light diffusion area are integrally formed, and the side of the incident part close to the light source 21 is at least one of a plane, a convex surface, and a concave surface structure. The shape of the incident part can be freely selected according to the actual required light path propagation direction on the light diffusion area 1.

[0037] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
