Description

a luminous panel

technical field

The invention relates to a board, in particular to a luminous board.

Background technique

At present, boards have been widely used in many occasions of daily production and life, such as interior decoration, advertising board production and so on. At present, the boards widely used in the fields of interior decoration and decoration generally include wood boards, three-ply boards, chemical boards, cement boards, fiber boards, metal boards, etc., which are used to produce furniture panels, or to decorate interior walls, ceilings, floors, and billboards etc.

In order to achieve a better decorative effect, currently many occasions need to use a board that can emit light (that is, a luminous board). However, with the glow panels currently on the market, glowing in the dark is often not ideal. For example, the luminescent panels currently on the market that rely on the self-luminescence of the rare earth material layer work on the principle of absorbing ambient light to store energy during the day, and releasing energy to emit light at night or in cloudy conditions. The plate can solve the problem that the pipe is not easy to be noticed when the light is dim to a certain extent, and has a decorative effect. However, when this kind of self-illuminating board works at night, there is often a problem that the brightness gradually decays with the prolongation of the use time; these luminous boards will generally decay to 10,000 millicantras in luminous intensity after 2 hours without external light , and then continue to decay. Also, it is likely to decay to the point where the tube is no longer easily identifiable by the naked eye and thus cannot play a decorative or lighting role.

Therefore, a new luminous panel needs to be proposed.

Embodiment one

Hereinafter, an exemplary structure of a light-emitting panel proposed in Embodiment 1 of the present invention will be described with reference to FIG. 1 to FIG. 4 . Fig. 1 is a cross-sectional view of a light-emitting panel proposed in Embodiment 1 of the present invention; Fig. 2 is a top view of a light-emitting panel proposed in Embodiment 1 of the present invention; Fig. 3 is another light-emitting panel proposed in Embodiment 1 of the present invention FIG. 4 is a cross-sectional view of another light-emitting panel proposed in Embodiment 1 of the present invention; FIG. 5 is a block diagram of an active lamp system included in a light-emitting panel proposed in Embodiment 1 of the present invention.

Embodiment 1 of the present invention provides a light-emitting panel, as shown in FIG. 1 , including a substrate 11 , a light-emitting layer 12 covering the upper surface of the substrate, and at least one lamp bead 131 embedded in the light-emitting layer 12 . Wherein, the light-emitting layer 12 is a rare-earth light-emitting layer; the lamp bead 131 is an electrically driven lamp bead.

Among them, the electrically driven lamp bead refers to a lamp bead driven by electric energy to emit light. In the embodiment of the present invention, the lamp bead 131 can be driven by civilian lighting electricity, industrial electricity, solar cell power generation, various batteries, etc., and is not limited here. Wherein, the power line of the lamp bead 131 can be arranged inside the substrate 11, can be arranged between the upper surface of the substrate 11 and the lower surface of the light-emitting layer 12, or can be arranged in any other suitable way, which is not limited here. . The lamp beads 131 can be various suitable light sources, which are not limited here. Moreover, the lamp bead 131 can be a white light source or a colored light source; when there are multiple lamp beads 131, each lamp bead 131 can emit light of the same color or light of different colors, which is not limited here .

Regarding the substrate 11, it can be various boards such as metal boards, plastic boards, fiber boards, wood boards, and cement boards. Moreover, the substrate 11 can be a single-layer structure as shown in FIG. 1 or a multi-layer structure, and when it is a multi-layer structure, the materials of each layer can be the same or different. This embodiment does not limit the shape of the substrate 11 , and its shape (referring to the top view) can be rectangular, circular or any other shape, which is not limited here. The shapes of the layers on the substrate 11 (including the light-emitting layer 12 in FIG. 1 , and the reflective layer and transparent protective layer described below) are generally consistent with the shape of the substrate 11 , but are not limited here.

Wherein, the luminescent layer 12 can be made of various rare earth luminescent materials in the prior art, which is not limited here. Preferably, in the embodiment of the present invention, the components of the luminescent layer and the mass content of the components are: 26-38% of rare earth aluminate luminescent powder, 15-25% of glass powder, 1-2% of hardener, flame retardant Agent 10-25%, nano cerium oxide 0.5-1% and nano titanium oxide 0.5-1%, and unsaturated transparent resin of corresponding quality. Compared with the prior art, the light-emitting layer with this composition can improve the self-luminous efficiency of the light-emitting layer, and the formed light-emitting layer 12 has the advantages of not easy to fall off and crack, high hardness, and long life.

In the embodiment of the present invention, although the self-luminous intensity of the luminous layer 12 will gradually decrease with the prolongation of the use time (such as night time), and even eventually cause the luminous plate to be difficult to be recognized by the naked eye, and cannot play a decorative or even lighting role. However, since the luminous board also includes lamp beads 131, the brightness of the luminous board can be further improved by turning on the lamp bead 131, so the overall brightness of the luminous board can meet actual needs, and play the role of decoration and lighting in a dark environment. Moreover, the light emitted by the lamp bead 131 can also further excite the luminescent layer 12 to emit light, further enhancing the brightness of the entire luminescent panel.

Further, in this embodiment, the luminescent panel further includes: at least one solar cell 132 disposed in the luminescent layer 12 , as shown in FIG. 1 . Wherein, the solar cell 132 is mainly used to absorb sunlight or other ambient light and convert light energy into electrical energy, so as to provide electrical energy for the lamp bead 131 . The solar cell 132 may be a silicon solar cell, a nanocrystalline solar cell, or the like. In this embodiment, the lamp bead 131 and the solar cell 132 form an active lamp system 13 , which is different from the passive light emitting layer 12 . What needs to be explained is that active light emission means that the light source itself needs to consume electric energy (including electric energy converted from solar energy) to emit light. Passive lighting means that when the light source emits light, it does not need to consume electric energy.

In this embodiment, the active light system 13 may include other elements besides the lamp bead 131 and the solar cell 132 . Fig. 5 shows a block diagram of an active light system 13 included in a luminescent panel according to an embodiment of the present invention, the active light system 13 not only includes lamp beads 131 and solar cells 132, but also includes a storage battery 133 and a control circuit 134 . Wherein, the battery 133 is connected with the solar battery 132 and the lamp bead 131 ; the control circuit 134 is connected with the battery 133 and the lamp bead 131 , as shown in FIG. 3 .

In the embodiment of the present invention, the storage battery 133 can be arranged inside the substrate 11, can be arranged outside the substrate 11 (referring to the side opposite to the light-emitting layer 12), can be arranged inside the light-emitting layer 12, can be arranged between the light-emitting layer 12 and The substrates 11 can also be arranged in any other suitable way, which is not limited here. Moreover, the control circuit 134 can be arranged on the outside of the substrate 11 (referring to the side opposite to the light-emitting layer 12), can be arranged in the light-emitting layer 12, can be arranged between the light-emitting layer 12 and the substrate 11, and can also be arranged in any other suitable manner. The method for setting is not limited here.

Wherein, the main function of the control circuit 134 is to control the on and off of the lamp bead 131 by controlling the battery 133 .

In the embodiment of the present invention, although the light-emitting layer 12 of the light-emitting board emits light by itself when the light is weak, the light intensity will gradually decrease with the extension of the use time (such as night time), but since the light-emitting board also includes lamp beads 131, Therefore, the light-emitting layer 12 can be excited by turning on the lamp bead 131 to enhance the light intensity (ie, brightness) of the entire light-emitting panel, so that the light intensity of the entire light-emitting panel can be controlled within an appropriate range. For example, the control circuit 134 can be used to control the lamp bead 131 to turn on for a period of time and then turn off for a period of time to emit light intermittently, so that the light intensity of the entire luminescent panel is consistent throughout the night (for example, the light intensity is consistent with when it was just dark). For another example, if there is no human activity in the environment where the light-emitting board is located late at night, the lamp bead 131 can not be turned on in the middle of the night, or the lamp bead 131 can be turned on but controlled at a smaller light intensity to save power. The light intensity of the entire luminescent panel can be set according to actual specific needs, which is not limited in this embodiment. That is to say, in this embodiment, the function of the lamp bead 131 is mainly to compensate the energy required for the light emission of the light emitting layer 12 . In this way, the light-emitting board can generally keep the luminous intensity above 20,000 millicantels for about 3 days, so that it can better replace the weak current, better play the function of the light-emitting board, and better play the role of beautification and decoration.

In this embodiment, the control circuit 134 may include a timing circuit (not shown in the figure) for controlling the turn-on and turn-off times of the lamp bead 131 , and the timing circuit may control which period of a day the lamp bead 131 is turned on. More preferably, the timing circuit can also control the lamp bead 131 to turn on at different time periods in different seasons.

In this embodiment, the control circuit 134 may further include: a light intensity sensing circuit for sensing the light intensity of the surrounding environment; and a light intensity control circuit for controlling the light intensity of the lamp bead 131 . The light intensity sensing circuit can sense the light intensity around the luminescent panel in real time, and the light intensity control circuit can control the light intensity of the lamp beads 131 in real time, thereby achieving the effect of controlling the light intensity of the entire luminescent panel.

Further, in this embodiment, the control circuit 134 may also include an overcharge protection circuit, so as to prevent the storage battery 133 from being damaged due to overcharging.

Further, in this embodiment, a groove (not shown in FIG. 1 ) can be provided on the substrate 11, and the lamp bead 131 can be embedded in the groove, so that the lamp bead 131 can be firmly fixed on the substrate 11 , improve the reliability of the entire luminous panel.

In this embodiment, the lamp beads 131 can be arranged in various feasible ways on the light emitting board, which is not limited here. Exemplarily, there are a plurality of lamp beads 131 , and the plurality of lamp beads 131 are arranged along the length direction of the substrate 11 to form a plurality of light bars, and the distances between adjacent light bars are equal. Furthermore, the lamp beads 131 on adjacent lamp bars can be arranged in a staggered manner. This exemplary arrangement can make the lamp beads 131 more evenly distributed on the entire luminous panel, and further make the luminous panel emit light in all directions more uniformly.

The shape of the light-emitting panel in the embodiment of the present invention can be rectangular (referring to the top view), as shown in Figure 2; it can also be circular (referring to the top view), as shown in Figure 3; of course, it can also be any other suitable shape , is not limited here. Among them, FIG. 2 is a top view of a luminescent panel proposed in Embodiment 1 of the present invention (solar cells 132 are not shown), and FIG. 3 is a top view of another luminescent panel proposed in Embodiment 1 of the present invention (solar cells 132 are not shown). 132); they show two different shapes of the luminous board and the arrangement of lamp beads 131 on the luminous board, wherein 12 is the luminous layer.

The lamp bead 131 in this embodiment only needs to ensure that it can emit light waves that excite the luminescent layer 12 to emit light, and the color and wavelength of the emitted light are not limited. In order to obtain a better viewing effect, you can choose to use lamp beads 131 that can emit one or more types of light such as white light, green light, purple light, ultraviolet light or yellow light (you can emit more than one type of light by setting more than two lamp beads). light). light emitting board

Fig. 4 shows a cross-sectional view of another light-emitting panel proposed by an embodiment of the present invention. As shown in FIG. 4 , the light-emitting panel of the embodiment of the present invention includes a substrate 11, a light-emitting layer 12 covering the upper surface of the substrate, at least one lamp bead 131 embedded in the light-emitting layer 12, and at least one lamp bead 131 located in the light-emitting layer 12. In addition to a solar cell 132 , it may also include a reflective layer 14 disposed between the substrate 11 and the luminescent layer 12 , and the lamp beads 131 are located outside the reflective layer 14 and are completely embedded in the luminescent layer 12 .

Wherein, the reflective layer 14 may be various materials whose luminous effect is stronger than that of the outer surface of the substrate 11 . Its function is to increase the reflectivity to make full use of the light emitted by the light-emitting layer 12 and the lamp bead 131 and increase the light extraction rate. Of course, the reflective layer 14 may also be omitted, and the reflectivity of the upper surface of the substrate 11 may be improved by polishing, that is, the substrate 11 whose upper surface has been polished is used.

Further, the luminescent board further includes a transparent protective layer 15 covering the luminescent layer 12 and the lamp beads 131 , as shown in FIG. 4 . The function of the transparent protective layer 15 is to prevent the luminous layer 12 from aging and discoloration due to the influence of moisture, ultraviolet rays and other factors in the environment, and to prevent the luminous layer 12 and the lamp beads 131 from being corroded or scratched due to direct contact with other objects. The service life of the light emitting board. The transparent protective layer 15 can be various transparent materials with high light transmittance and functions such as waterproof, UV protection, corrosion resistance, and scratch resistance. Preferably, the transparent protective layer 15 is made of nano cerium oxide and PU varnish, and the mass ratio of PU varnish to nano cerium oxide is 10:0.05-10:0.1. The transparent protective layer 15 of this composition has better light transmittance and better waterproof, anti-ultraviolet, anti-corrosion and anti-scratch effects.

Furthermore, in the embodiment of the present invention, the area of the transparent protective layer 15 covering the lamp bead 131 can be made into a convex lens structure, that is, a convex lens structure 151 is formed on the position of the transparent protective layer 15 corresponding to the lamp bead 131, as shown in the figure 2. This structure can condense the light emitted by the lamp bead 131, improve the brightness of the lamp bead 131, and further improve the brightness of the luminous panel. Therefore, the light-emitting board can play a better role in lighting and decoration.

The light-emitting panel provided by the embodiment of the present invention includes at least one electrically driven lamp bead 131 embedded in the light-emitting layer 12, so when the light-emitting brightness of the light-emitting layer 12 alone cannot meet the requirements, the light bead 131 can be powered on to make light. If the light emitted by the selected lamp bead 131 is relatively obvious visible light, the light emitted by the lamp bead 131 can not only play the role of illumination and decoration, but also can further excite the light-emitting layer 12 to emit light. In this way, the light-emitting board can generally keep the luminous intensity above 20,000 millicantels for about 3 days, so that it can better replace the weak current, better play the function of the light-emitting board, and better play the role of beautification and decoration. It can be seen that the light-emitting board of the embodiment of the present invention is more practical than the ordinary self-luminous board; and, because the lamp beads 12 can be set in different colors, the light-emitting board can emit light of various colors, so it is more aesthetically pleasing .
