fig. 3 is a schematic exploded view of a preferred embodiment of the wall decoration panel of the present invention.

Detailed Description

The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein identical components may be provided with different labels in different drawings because of the need for separate description, but without affecting the presentation of the technical solution. Fig. 1 shows the outer surface structure of the wall decoration panel of the present invention more visually and expressed by means of a positive and a negative contrast. Such wall decoration panels have a light-permeable first layer board 1, which first layer board 1 as wall decoration panel allows the user to directly contact to its front surface 15, so that it is not necessary to provide a metal surface to avoid electric shock when used in wall sockets, electrical gate switches. Preferably, the surface electrostatically processed film spray process is also used to optimize the feel of use. In the embodiment of fig. 1, the first laminate 1 is formed with the first concave portion 16 inwardly from the rear surface 10, and since the first laminate 1 is entirely made of transparent or translucent material, light incident from any surface of the first laminate 1 can be refracted in the first concave portion 16 to create a more attractive curved surface appearance of the first laminate 1 after being assembled to the wall electrical accessory device. I.e. a raised "foam" like the broken line representation of the front view in fig. 1.

Preferably, the recess has a bottom surface 103 and a curved surface 102 extending outwardly from the bottom surface 103, wherein the bottom surface 103 may be provided as a flat surface for providing electronic components, such as buttons, electrical sockets or indication means, etc., for functions related to the wall means on the flat surface. Alternatively, the bottom surface 103 may be manufactured with a larger radius of curvature than the curved surface 102 to appear flatter.

On the basis of this, the first recess 16 may have a predetermined thickness and be formed as an applied layer having a lower light transmittance than the host material of the first laminate 1. Thus, when the wall decoration panel is installed, the first concave portion 16 of lower light transmittance may appear more prominent in the inner contour of the translucent first laminate 1. In addition, any suitable fine pattern may be doped or sprayed into the application layer to increase the aesthetic appearance.

Fig. 1 and 2 also show another embodiment. The wall decoration panel is also provided with a second layer plate 2 attached to the first layer plate 1, and the second layer plate 2 is used for being fixed on a wall electrician accessory device. For example, the second laminate 2 also has a convex portion (or coating layer) 11 configured to match the first concave portion 16 of the first laminate 1, instead of the thickened inner surface of the first concave portion 16 itself. That is, the surface of the first concave portion 16 can be replaced by the convex portion 11 instead of the lower light transmittance processing layer, and the user can change the pattern or color therein to change the decoration pattern due to the assembly mode of laminating/embedding the convex portion. In other embodiments, the protruding portion may be configured as a combined structure, for example, a capacitive sensing layer may be embedded therein to sense the touch state of the user.

The front surface 15 may be provided with one or more second recesses 101 for a user to touch for use with a neutral or plug, and thus electrical components such as switch contacts, electrical sockets, etc. are provided at the bottom surface of said second recesses 101. The purpose of this design is to compromise the numerical relationship between the thickness of the first and/or second laminate and the effective electrical contact distance. The designer found that in some implementations it was necessary to add a second layer to significantly enhance the apparent effect of such a light guiding design, because the greater the thickness, the greater the volume of the overall participation in light guiding, and the more obvious and aesthetically pleasing the overall profile of the protrusion 11, under the precondition that the area of the wall assembly is constrained. But does not affect the electrical characteristics of the wall unit itself, such as the effective contact area for the socket to plug into. In addition, the second laminate 2 may be molded using a transparent or translucent material, but it has a higher rigidity and a lower light transmittance than the first laminate 1, so that the other portions of the rear surface 10 than the first concave portion 16 may be provided with a certain light reflection effect. Also according to the above embodiment, the second laminate 2 is used for fastening and mounting on the wall device, and the inner side thereof may be provided with a fastening portion 204 for mounting and dismounting.

Fig. 2 schematically depicts an example of the use of such a wall decoration panel. According to the foregoing embodiment, the high light transmittance region of the first laminate 1 is expressed by a hatched portion, the bottom of which is the first concave portion 16, and the forward lighting circuit can be provided by the functional board 31 provided on the rear surface of the second laminate 2. For example, one or more LED light sources 311 may be used to project light (beams) 341 into the first and second laminate 1 and out to the outside environment after refraction. Preferably, the first recess 16 may have a protrusion 11 of a certain size applied to the surface thereof, and in this embodiment, the protrusion 16 may be provided as a capacitive sensing layer to sense the clicking action of the finger or the capacitive pen of the user 6 through the relatively thin bottom surface 103 area of the first layer plate 1. The second recess 101 may be designed with a larger diameter for user access. In this arrangement, the area of the contact of the finger of the user 6 is smaller than the area of the light transmission of the LED, so that the user can more easily observe the optical feedback signal of the click action by the function board 31 around his finger. For example, when the user 6 presses one of the keys on the front surface 15, only a certain area around the key generates a change in the light and shadow. Further, a conductive contact 223 is provided on the second laminate 2 to communicate an electrical signal to a sensor or a controller on the function board 31 to receive identification.

Fig. 3 provides a specific example of an electrical accessory device based on the above embodiments. Fig. 3 depicts the main functional components of the accessory device in more detail, which also includes a preferred assembly of the wall trim panel into an electrical assembly. According to the above embodiment, the first laminate 1 and the second laminate 2 laminated on each other are fixedly mounted on the surface of the base 3 as the operation surface for the user. The base 3 is fixed by being embedded in a building wall and obtains building power through terminal buttons 322 on the power panel 32. The building power may not only be zero line (L/N) but also include other power buses, such as an RS485 bus for controlling air conditioners based on a carrier wave, a PoE dimming bus for controlling low voltage lighting appliances, or a Home-bus protocol bus for controlling other household appliances, etc. The cavity 30 of the base 3 is used for mounting the power panel 32 to convert the building power into the power or control level signals required by the function panel 31. This is because when used as a dimmer switch, it is necessary to continuously output a control electrical signal to trigger an electrodeless dimming command to a remote lighting device.

As an optimization scheme, the power panel 32 and the functional panel 31 can be electrically connected through the conductive connector 321 (or any inter-panel connector element) in a plugging manner, and simultaneously transmit control electric signals. For example, the sensed click is recognized by the controller 312 on the function board 31 to generate a capacitance to trigger an action of an electric switching element such as the magnetic latching relay 323 on the power board 32. And the controller 312 triggers one or more LED light sources 311 disposed on the function board 31 to emit light or provide a light-shadow indication (e.g. flashing, color change, etc.) to prompt the user according to the fed-back on-off switch signal. Also, such light and shade indications may be preprogrammed or custom (e.g., when used alone as a smart night light function) into the controller 312 to generate corresponding light effects in accordance with the user's different point-presses or operations on the panel.

In addition, to achieve functional control of the night light, the power supply circuit 324 on the power board 32 is modified again to achieve current regulation of the LED light source 311. For example, the boost circuit may be provided to the array of LED light sources 311 or in parallel, depending on the LED light source type, characteristics, and/or lumen class. The power circuit 324 further includes a plurality of branches for supplying power to other components on the function board 31, such as the controller 312, a wired/wireless communication module (not shown), and the like. For example, the controller 312 may use a Local Area Network (LAN) like a Wi-Fi network and/or point-to-point communication (e.g., bluetooth Low energy B-LE) to communicate with external smart devices or receive setup instructions.

The functional board 31 and the power board 32 are assembled and connected with each other, and then fixed in the inner cavity 30 and covered by the lining board 22. For example, the cover plate 31 may be used to position the individual circuit boards by fasteners (e.g., screws, fixing posts, etc.). A conductive contact 223 (or pin) of metal extends from the backing 22 (preferably centrally) as an insulating pad to extend to the location of the boss 11 so as to be electrically coupled through its contact 112 when the boss 11 is used as a capacitive sensing layer, and through the conductive contact 223 into the electrical contact 313 to transmit one or more capacitance signals. For this purpose, the backing 22 is provided with one or more perforations 222 for inserting the conductive contacts 223.

Preferably, the lining board 22 is further perforated with one or more light guiding holes 221, and the shape of such light guiding holes can be concave with a certain slope in the direction towards the inner cavity 30, so that the lining board 22 has a predetermined thickness and the light guiding holes 221 are abutted to the positions of the LED light sources 311 on the functional board 31 to avoid light leakage.

On the basis, an isolation light guide plate 21 can be additionally arranged between the lining plate 22 and the second layer plate 2, so that the LED light can be guided. The isolated light guide plate 21 may be made of a transparent or translucent PC material. And the isolated light guide plate 21 can be used for supporting and positioning between the lining plate 22 and the second layer plate 2.

The front surface of the second laminate 2 is provided with a boss 20 and the surface of the boss 20 has a radius of curvature to match the configuration of the rear surface of the first laminate 1. Thus, one or more protrusions 11 can be laminated or embedded between the boss 20 and the first recess 16 of the first layer 1. In a preferred example, the protrusions 11 can be manufactured as standard form pieces (as depicted in fig. 3) to facilitate embedding a corresponding protrusion 11 for different numbers or shapes of button positions.

As can be appreciated from the above examples, the protruding portions 11 may be transparent capacitive plates commonly used at present, or may be opaque metal mesh films used in other embodiments to sense electric variables (e.g. sensing signals of pyroelectric human body, micro signals close to sensing electric signals, etc.), and at this time, the light holes 111 with the same or similar shape as the light guide holes 221 are formed in each protruding portion 11. In this embodiment, the second layer 2 is also provided with light holes 201 (or alternatively, light guiding structures may be designed) at corresponding positions so that the LED light is mainly directed to the periphery of each second concave portion 101 to form a "halo".

In the above-mentioned embodiments, since the electrical accessory device itself is installed as a wall electrical apparatus, when describing its specific structure or electronic function, a direction toward the outside of the building wall is generally referred to as "front/outside" and vice versa as "rear/inside", and when describing a part of the construction, the front, rear, etc. relationship is also described in terms of such a direction. For example, the light emitting direction of the LED light source 311 is also expressed in terms of "forward". While in some embodiments, "mounted on" is sometimes also meant to be mounted on a surface thereof and should not be misinterpreted as an up/down position. "area" means a readable, identifiable active area or volume portion of an electronic function, such as when a touch is applied with a finger to a capacitive conductive sheet, the description of an area thereof also generally refers to any active location of random touch and encompasses a portion of the area around it, so the feature "second recess 101" may be designed larger so as to have a larger contact area.
