With the development of automobiles, in order to improve the technological and aesthetic senses of vehicles, decorative panels of vehicles may be made of light-emitting panels to display a predetermined light-emitting effect. The vehicle trim panel may be a B-pillar trim panel, a D-pillar trim panel, a spoiler, an interior trim panel, or the like.
In the related art, the light emitting panel includes a color changing panel and a light source. The color-changing plate comprises a transparent protective layer, an electrochromic assembly layer, a light guide layer and a substrate layer which are arranged in a stacked mode. The electrochromic assembly layer is electrically connected with the controller, so that the color of the electrochromic assembly layer can be changed. The light source is installed on the automobile body and is connected with the controller, and the light source is arranged beside the light guide layer. The light guide layer is used for diffusing light generated by the light source, so that the light generated by the light source can enter the electrochromic component layer.
However, the light source and the color changing plate are of a split structure, so that the assembly efficiency of the vehicle is low.
Through careful analysis, the inventors of the present disclosure considered that the main reason why the above-mentioned problems occur is that the light source and the color-changing plate are respectively installed on the vehicle body, so that at least two steps are required for assembling the light-emitting plate with the vehicle body, thereby making the assembling time of the light-emitting plate excessively long, and further resulting in inefficient assembly of the vehicle. In addition, in the assembling process of the light source and the color changing plate, the distance between the light source and the color changing plate needs to be ensured to ensure that the light emitted by the light source can enter the color changing plate, so that the assembling efficiency of the light emitting plate is further limited.
In view of the above, the inventors of the present disclosure provide a light emitting panel of an integrated structure, which is assembled with a vehicle body in one step, thereby shortening the assembly time of the light emitting panel and further improving the assembly efficiency of the vehicle. Specifically, the light emitting panel of the present disclosure includes an electrochromic component layer, a light guide layer, and a light source. Light guide layer and light source interval set up on electrochromic subassembly layer's same surface to light source and light guide layer respectively with electrochromic subassembly layer fastening connection. The effect on leaded light layer is the produced light of divergent light source to make everywhere homoenergetic of electrochromic subassembly layer have the light that the light source produced to see through, with the luminous effect of assurance luminescent plate, thereby guarantee the luminous effect of luminescent plate under the low light environment. The light source functions to provide light through the electrochromic device layer so that the luminous effect of the luminescent panel satisfies the luminous demand in a low light environment. The low-light environment may be a dark environment, a cloudy environment, or a fog environment.
The light-emitting panel and the automobile provided by the utility model are described in detail with reference to specific embodiments.
Fig. 1 is a sectional view of a light emitting panel of the present embodiment.
The present embodiment provides a light emitting panel, as shown in fig. 1, including: an electrochromic assembly layer 100 for electrical connection with a controller; a transparent protective layer 200 disposed on a first surface of the electrochromic assembly layer 100; a light source 300 and a light guide layer 400 disposed on the second surface of the electrochromic assembly layer 100, the light source 300 being for electrically connecting with the controller, the light guide layer 400 being for diffusing light generated by the light source 300; the second surface is parallel to the first surface and is arranged at intervals; a substrate layer 500 disposed on the light guide layer 400, the light guide layer 400 being located between the electrochromic assembly layer 100 and the substrate layer 500.
Since the light source 300 is disposed on the electrochromic assembly layer 100, the light-emitting panel may be assembled in advance before the light-emitting panel is assembled with the automobile body, and then the light-emitting panel is assembled with the automobile body in one step. So set up, simplified the assembling process of luminescent plate and automobile body to improve the assembly efficiency of luminescent plate, and then improved the assembly efficiency of vehicle. In addition, the light source 300 is disposed on the electrochromic device layer 100, the area of the region required for mounting the light emitting panel can be reduced, so that the volume of the light emitting panel can be made smaller, and the light emitting panel is applied to a small-sized decorative panel or a complicated mounting region.
The transparency of the transparent protection layer 200 means that the transparent protection layer 200 can be made of transparent material to ensure the light to pass through, so as to ensure the light emitting effect of the light emitting panel. In addition, the transparent protection layer 200 can protect the electrochromic device layer 100 from being damaged by accidental impact or water or the like.
The light guide layer 400 is made of a material through which light can pass, so as to ensure the light emitting effect of the light emitting panel. In addition, the divergence principle of the light guide layer 400 is as follows: after the light generated by the light source 300 enters the light guide layer 400, the light is totally reflected and diffusely reflected in the light guide layer 400, then the light is emitted from all parts of the light guide layer 400 and enters the electrochromic assembly layer 100, and finally the light passes through the transparent protection layer 200 and enters the outside, so that the light emitting effect of the light emitting plate is presented.
One of the functions of the substrate layer 500 is to protect the electrochromic device layer 100 from damage to the electrochromic device layer 100. The substrate layer 500 functions as the base structure of the light emitting panel. The substrate layer 500 serves a third purpose of enriching the color of the light-emitting panel. For example, when the electrochromic device layer 100 is in a transparent state, the color of the luminescent panel appears as the color of the substrate layer 500. The color of the substrate layer 500 may be an inherent color of the substrate layer 500, for example, the inherent color of the substrate layer 500 is a single color such as black, green, or purple, or a composite color of a plurality of colors. The color of the substrate layer 500 may be a base color layer sprayed on the substrate layer 500, for example, the base color layer may be a color such as green, plating color, or multicolor composite. Additionally, the base color layer may be located between the substrate layer 500 and the light guide layer 400, or the base color layer and the light guide layer 400 may be located on opposite sides of the substrate layer 500.
The electrochromic of the electrochromic device layer 100 means that the color of the electrochromic device layer 100 can be changed after the electrochromic device layer 100 is powered on, so that the luminous color of the luminescent panel is changed.
The electrochromic assembly layer 100 may be configured with a transparent state and a colored state. When the electrochromic device layer 100 is in a transparent state, the display color of the light-emitting panel is the color of the substrate layer 500. When the electrochromic device layer 100 is in the colored state, the color of the light-emitting panel is the color of the electrochromic device layer 100 in the colored state.
The electrochromic assembly layer 100 may be in a transparent state or a colored state in its normal state. When the electrochromic device layer 100 is normally transparent, the normal color of the light-emitting panel is the color of the substrate layer 500; when the electrochromic device layer 100 is energized, the electrochromic device layer 100 changes from the transparent state to the colored state, and the color of the light-emitting panel changes to the color of the electrochromic device layer 100 in the colored state. When the electrochromic element layer 100 is in a colored state in a normal state, the normal color of the light-emitting panel is the color of the electrochromic element layer 100 in the colored state; when the electrochromic device layer 100 is energized, the electrochromic device layer 100 changes from the colored state to the transparent state, and the color of the light-emitting panel changes to the color of the substrate layer 500.
When the electrochromic device layer 100 is in the colored state, the color of the electrochromic device layer 100 may be red, light red, dark red, yellow, white, green, purple, and the like, and is not particularly limited herein. Wherein, the current of the electrochromic device layer 100 can be adjusted to change the color of the electrochromic device layer 100 in the colored state. In addition, the color of the electrochromic assembly layer 100 in the colored state may be superimposed with the color of the substrate layer 500 and color saturation adjusted to achieve multi-level color adjustment of the light emitting panel.
In one possible implementation, the light guide layer 400 is made of a transparent material. For example, the light guide layer 400 is a polycarbonate plate or a polymethylmethacrylate plate.
In one possible implementation, the transparent protection layer 200 is made of a transparent material. For example, the transparent protective layer 200 is a glass plate, a polycarbonate plate, or a polymethylmethacrylate plate.
In one possible implementation, the substrate layer 500 is a glass plate, a polycarbonate plate, a polymethyl methacrylate plate, or a polypropylene plate or a polyethylene terephthalate plate.
It should be noted that the substrate layer 500 may also be provided with textures to enrich the display effect. For example, the substrate layer 500 may be provided with a wavy texture.
Fig. 2 is a cross-sectional view of the electrochromic device layer of this embodiment.
In one possible implementation, as shown in fig. 2, the electrochromic assembly layer 100 includes a first transparent conductive layer 110, an electrochromic layer 120, and a second transparent conductive layer 130, which are stacked. The first transparent conductive layer 110 is electrically connected to a controller and is in contact with the transparent protection layer 200 or the light guide layer 400. The second transparent conductive layer 130 is used for electrically connecting with a controller and for contacting with the transparent protection layer 200 or the light guide layer 400. The first transparent conductive layer 110, the second transparent conductive layer 130 and the electrochromic layer 120 define an electrical circuit, and by controlling the on/off of the electrical circuit, the electrochromic layer 120 can be switched between a transparent state and a colored state, so as to change the color of the electrochromic layer 120, and further change the color of the electrochromic device layer 100.
Transparent means that the first transparent conductive layer 110 and the second transparent conductive layer 130 are made of transparent materials to ensure light to pass through, thereby ensuring the light emitting effect of the light emitting panel. By conductive, it is meant that both the first transparent conductive layer 110 and the second transparent conductive layer 130 are made of a conductive material to ensure that the electrochromic layer 120 is able to get powered. Accordingly, the first transparent conductive layer 110 and the second transparent conductive layer 130 are both made of a transparent and conductive material. For example, at least one of a transparent conductive oxide and nano silver, or, a metal oxide. Specifically, the first transparent conductive layer 110 is an ito layer, a fluorine-doped ito layer, or a tungsten oxide. The second transparent conductive layer 130 is an ito layer, an oxyfluoride-doped ito layer, or a tungsten oxide. In addition, the first transparent conductive layer 110 and the second transparent conductive layer 130 may also be a nano silver wire film or a nano silver fiber array.
The electrochromic layer 120 may be made of an electrochromic material. Accordingly, the electrochromic layer 120 may be an inorganic electrochromic layer 120 or an organic electrochromic layer 120. Wherein the inorganic electrochromic layer 120 is made of an inorganic electrochromic material. The organic electrochromic layer 120 is made of an organic electrochromic material. For example, the organic electrochromic layer 120 is made of a conductive polymer. Specifically, the material of the conductive polymer may be polythiophene, polycarbazole, polypyrrole, or the like. The organic electrochromic layer 120 may be made of small organic molecules. In addition, the inorganic electrochromic layer 120 may also be formed by a transition metal oxide or derivative, for example, a WO thin film.
The electrochromic layer 120 may be a flexible or semi-flexible substrate film in the technology of Polymer Dispersed Liquid Crystal (PDLC), Suspended Particle Devices (SPD), or the like.
The light transmittance of the electrochromic layer 120 may be determined according to design requirements, and is not particularly limited herein. For example, the electrochromic layer 120 has a light transmittance of 0 to 50%. In addition, the discoloration reaction time of the electrochromic layer 120 may be determined according to the area of the color-changing glass, and is not particularly limited herein. For example, the electrochromic reaction time of the electrochromic layer 120 is less than 1 second. When the area of the reaction plate is large, the color-changing reaction time can be prolonged, for example, the color-changing reaction time can be controlled to be 1-60S seconds.
It should be noted that the color of the electrochromic layer 120 in the colored state can be adjusted by adjusting the voltage of the electric field in which the electrochromic layer 120 is exposed or the current passing through the electrochromic layer 120.
By adjusting the voltage of the first transparent conductive layer 110 and the second transparent conductive layer 130 to the electrochromic layer 120, the color of the electrochromic layer 120 can be changed, so that the electrochromic device layer 100 has a transparent state or a colored state. Wherein the color in the transparent state is the color of the electrochromic layer 120, and the color in the colored state is the color of the electrochromic layer 120 after coloring.
Fig. 3 is a schematic view of the color changing portion of the present embodiment.
In one possible implementation, as shown in fig. 3, the electrochromic assembly layer 100 includes a plurality of color-changing portions 140 disposed in insulation from each other; the discoloring parts 140 are plate-shaped structures, and each discoloring part 140 is electrically connected with the controller. Through the above arrangement, the light transmittance of each color changing part 140 may be different, so that the color of each color changing part 140 after coloring is different, and thus, the partial region of the electrochromic assembly layer 100 may be in a colored state, and the partial region of the electrochromic assembly layer 100 may be in a transparent state, so as to enrich the light emitting effect of the light emitting panel. In addition, color superposition or color saturation adjustment can be performed in cooperation with the color of the substrate layer 500 to enrich the color rendering of the light emitting panel.
The shape of the color-changing portion 140 may be a circle or a polygon, and is not particularly limited herein. In addition, the color-changing portion 140 at the corresponding position can be selected for color development according to the display requirement. For example, a plurality of color-changing portions 140 defining a circle.
A plurality of discolour portion 140 mutual insulation setting to every discolour portion 140 is connected with the controller electricity, makes electrochromic subassembly layer 100 carry out the chronogenesis break-make according to predetermined demonstration demand, thereby the color development of luminescent plate switches, changes according to the chronogenesis. For example, the plurality of color changing portions 140 arranged in parallel and at intervals have a display effect of sequentially turning on or off for a predetermined time.
In one possible implementation, the electrochromic assembly layer 100 is bonded to the transparent protective layer 200 and the light guide layer 400, respectively. For example, a first adhesive layer (not shown) is disposed between the electrochromic device layer 100 and the transparent protective layer 200. A second adhesive layer (not shown) is disposed between the electrochromic device layer 100 and the light guide layer 400.
It should be noted that the electrochromic device layer 100 may also be fixedly connected to the transparent protection layer 200 and the light guide layer 400 by welding or fusing.
In one possible implementation, a third adhesive layer (not shown) is disposed between the light guide layer 400 and the substrate layer 500, such that the substrate layer 500 is securely mounted on the light guide layer 400.
The light guide layer 400 may be fastened and connected to the substrate layer 500 by welding or fusing.
In one possible implementation, the light source 300 may be securely attached to the electrochromic assembly layer 100 by bonding or snapping, etc. For example, a fourth adhesive layer (not shown) is disposed between the light source 300 and the electrochromic device layer 100. In addition, when the electrochromic assembly layer 100 is bonded to the light guide layer 400, the light source 300 and the light guide layer 400 may be securely connected to the electrochromic assembly layer 100 through the same bonding layer.
Fig. 4 is a sectional view of a light source of the present embodiment.
In one possible implementation, as shown in fig. 4, the light source 300 includes a substrate portion 310 and a light source portion 320. Wherein the light source portion 320 is mounted on the substrate portion 310 and electrically connected to the controller, and the light source portion 320 is located between the substrate portion 310 and the light guide layer 400, and at least a portion of the light source portion 320 is located between the substrate layer 500 and the electrochromic assembly layer 100. The substrate portion 310 is tightly connected to the electrochromic device layer 100, so that light generated by the light source portion 320 can enter the light guide layer 400, thereby ensuring a light emitting effect in a low light environment.
The substrate portion 310 functions as a carrier of the light source portion 320 to mount the light source portion 320 in a predetermined position, and the specific material and structure of the substrate portion 310 are not limited herein. For example, the substrate portion 310 has a plate-like structure or a plate-like frame structure, or the substrate portion 310 is a pcb (printed Circuit board) board. When the substrate portion 310 is a PCB, the light source portion 320 may be integrated on the PCB, so as to facilitate opening and closing of the light source portion 320 and reduce the volume of the light source 300.
The light source unit 320 may be a light source 300 such as an LED (light emitting diode) or a bulb. When the light source part 320 is an LED, and the substrate part 310 is a PCB, the light source part 320 may be integrally disposed on the PCB, so that the manufacturing efficiency of the light source 300 may be improved.
It should be further noted that the light source 320 may be at least one of the surface light source 300, the line light source 300 or the point light source 300, and the number of the light source 320 is at least one, which is not particularly limited herein. For example, when the light source unit 320 is the point light source 300, the plurality of light source units 320 are provided on the substrate unit 310 at intervals.
At least a portion of the light source unit 320 is located between the substrate layer 500 and the electrochromic element layer 100, such that the light source unit 320 is disposed close to the light guide layer 400, thereby reducing the attenuation of the light generated by the light source unit 320 and allowing most of the light generated by the light source unit 320 to enter the light guide layer 400. In addition, with such an arrangement, the compactness of the light emitting panel can also be improved.
FIG. 5 is a cross-sectional view of yet another light-emitting panel of the present embodiment; fig. 6 is a schematic view of a pattern layer of the present embodiment; fig. 7 is a schematic view of another pattern layer of the present embodiment.
In one possible implementation, as shown in FIG. 5, a patterned layer 600 is disposed between the substrate layer 500 and the light guide layer 400. The pattern layer 600 includes a light-permeable ink portion 610 and a pattern hole portion 620 penetrating the ink portion 610. When the electrochromic device layer 100 is in a transparent state and light passes through the pattern layer 600, the light emitting panel may take the shape of the inner wall of the pattern hole part 620, so that the light emitting effect of the light emitting panel may be improved.
The pattern hole part 620 may be a circular hole, a polygonal hole, a circular ring, a polygonal ring, a pentagram, etc. In addition, the pattern hole part 620 may include a plurality of differently shaped sub-pattern parts, or the pattern hole part 620 may include a plurality of identically shaped sub-pattern parts. For example, as shown in fig. 6 and 7, the pattern hole part 620 includes a plurality of pentagonal holes or sub-pattern parts of rectangular holes.
The ink portion 610 may be made of any light-permeable ink known in the art, so that the color of the light may be changed after the light passes through the ink portion 610. Here, the ink portion 610 contains crystal particles that can reflect, diffuse, and diffract light rays of different spectra, so that when the electrochromic element layer 100 is in a transparent state, the colored shape of the light-emitting panel is the shape of the ink portion 610, and the area in the ink portion 610 where no color is developed is the shape of the pattern hole portion 620.
Fig. 8 is a sectional view of still another light emitting panel of the present embodiment.
In one possible implementation, as shown in fig. 8, a first patterned layer 630 and a second patterned layer 640 are disposed in a stacked arrangement between the substrate layer 500 and the electrochromic assembly layer 100, and the light guide layer 400 includes a first light guide layer 410 and a second light guide layer 420 disposed in a stacked arrangement. Wherein the first light guiding layer 410 is located between the electrochromic assembly layer 100 and the first pattern layer 630. The second light guiding layer 420 is located between the first patterned layer 630 and the second patterned layer 640, and the second light guiding layer 420 is in contact with the substrate layer 500. Through the arrangement, the light-emitting effect of the light-emitting plate can be improved.
Both the first light guide layer 410 and the second light guide layer 420 may be made of a transparent material, for example, both the first light guide layer 410 and the second light guide layer 420 may be a polycarbonate plate or a polymethyl methacrylate plate.
The thicknesses of the first light guiding layer 410 and the second light guiding layer 420 may be the same or different, and are not particularly limited herein.
The arrangement of the first light guide layer 410 and the second light guide layer 420 can ensure that light generated by the light source 300 uniformly enters the first pattern layer 630 and the second pattern layer 640, so that the light emitting effect of the light emitting plate is the superposition of the display colors of the first pattern layer 630 and the second pattern layer 640. Here, the coloring of the first and second pattern layers 630 and 640 is premised on the electrochromic device layer 100 being in a transparent state, so that the coloring of the light emitting panel is a colored superposition of the first and second pattern layers 630 and 640.
First light guiding layer 410 may be bonded to electrochromic assembly layer 100. In addition, the second light guide layer 420 may be bonded to the second pattern layer 640.
The arrangement of the first pattern layer 630 and the second pattern layer 640 can enrich the light emitting effect of the light emitting panel. For example, the first pattern layer 630 and the second pattern layer 640 define a plurality of patterns stacked in the thickness direction of the light emitting panel, and the patterns may be in the shape of a triangle, a rectangle, a circle, or the like, and are not particularly limited.
It should be noted that the structure of the first patterning layer 630 and the second patterning layer 640 is similar to that of the patterning layer 600. For example, the first pattern layer 630 includes a first ink portion that is light-transmissive and a first pattern hole portion that penetrates the first ink portion. The second pattern layer 640 includes a second ink portion that is light-transmissive and a second pattern hole portion that penetrates the second ink portion.
The first ink portion and the second ink portion may be made of the same material as the ink portion described above. In addition, the materials of the first ink portion and the second ink portion may be the same or different, and are not particularly limited herein.
The first pattern hole part may be a circular hole, a polygonal hole, a circular ring, a polygonal ring, a pentagram, or the like. In addition, the first pattern hole part may include a plurality of different shapes of the first sub-pattern parts, or the first pattern hole part may include a plurality of same shapes of the first sub-pattern parts. For example, the first pattern hole portion includes a sub-pattern portion of a plurality of pentagonal holes.
The second pattern hole part may be a circular hole, a polygonal hole, a circular ring, a polygonal ring, a pentagram, or the like. In addition, the second pattern hole part may include a plurality of different shapes of the second sub-pattern parts, or the second pattern hole part may include a plurality of same shapes of the second sub-pattern parts. For example, the second pattern hole portion includes a sub-pattern portion of a plurality of pentagonal holes.
It should be noted that, the shapes of the first pattern hole portion and the second pattern hole portion may be completely the same, or the shape of a part of the first pattern hole portion is the same as that of a part of the second pattern hole portion, which is not limited herein, and may be determined according to the display requirement, so that the light emitting effect of the light emitting panel is rich and varied.
Alternatively, the light source 300 includes a substrate portion 310 and a light source portion 320.
The light source 320 is mounted on the substrate 310 and electrically connected to the controller, the light source 320 is located between the substrate 310 and the first light guide layer 410, the light source 320 is disposed adjacent to the first light guide layer 410 and the second light guide layer 420, and light generated from the light source 320 can enter the first light guide layer 410 and the second light guide layer 420 respectively.
The light source unit 320 is a surface light source, or the light source unit 320 includes a plurality of point light sources, or the light source unit 320 includes a plurality of line light sources. When the light source 320 is a surface light source, the first light guide layer 410 and the second light guide layer 420 are both located in the light source 320.
The substrate portion 310 is tightly connected with the electrochromic assembly layer 100, and a gap is formed between the substrate portion 310 and the substrate layer 500; alternatively, the substrate section 310 is in surface contact with the substrate layer 500 and is securely connected to the electrochromic assembly layer 100.
The structures of the substrate portion 310 and the light source portion 320 have been described in detail above, and are not described in detail herein.
The substrate portion 310 is in surface contact with the substrate layer 500, so that light entering the first light guide layer 410 and the second light guide layer 420 can be improved, and waste of light generated by the light source portion 320 can be avoided.
Fig. 9 is a sectional view of still another light source of the present embodiment.
Alternatively, as shown in fig. 9, the light source 300 includes a substrate section 310, and a light-blocking section 330, a first light source section 340, and a second light source section 350 provided on the same surface of the substrate section 310.
Wherein the light blocking part 330 is disposed between the first light source part 340 and the second light source part 350 and serves to block light generated from the first light source part 340 from light generated from the second light source part 350. The substrate portion 310 is fastened to the electrochromic device layer 100, so that the first light guide layer 410 and the second light guide layer 420 can correspond to a light source respectively.
The light-blocking part 330 may have a plate-shaped structure, and the free end surface of the light-blocking part 330 may be in surface contact with the first pattern layer 630 or the second pattern layer 640 between the first light guide layer 410 and the second light guide layer 420, so as to ensure that the light-blocking part 330 completely blocks light rays at both sides thereof.
The light-blocking part 330 may be integrated with the substrate 310, so as to improve the connection strength between the light-blocking part 330 and the substrate 310, and further improve the service life of the light-emitting panel.
The colors of the light generated by the first light source part 340 and the second light source part 350 may be the same or different, and are not particularly limited herein. When the colors of the lights emitted from the inside of the first light source part 340 and the second light source part 350 are different, the light emitting effect of the light emitting panel can be enriched.
Each of the first light source unit 340 and the second light source unit 350 may be a light source 300 such as a light emitting diode or a bulb. In addition, the first light source part 340 may be a point light source, a line light source, or a surface light source, and the number of the first light source parts 340 is at least one, which is not particularly limited herein. Similarly, the second light source part 350 may be a point light source, a line light source, or a surface light source, and the number of the second light source parts 350 is at least one, which is not particularly limited herein.
The embodiment also provides an automobile which comprises a controller and the light emitting panel. Wherein the controller is electrically connected to the electrochromic assembly layer 100 of the light emitting panel and the light source 300, respectively.
It is understood that the controller can control the on/off of the electrochromic device layer 100 and the light source 300 according to a preset light emitting program, so that the light emitting panel can present light emitting effects of different styles and colors. In addition, the controller can be a single chip microcomputer, a circuit board, a programmable logic controller or other components with control functions. For example, where the light panel is used in an automobile, the controller may be an electronic control unit of the vehicle.
