[0048] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0049] like Figure 1 As shown, the electronic device provided by the present application includes a light emitting module 1 and a dimming module 2.

[0050] The light emitting module 1 is used for emitting fill light; the dimming module 2 is used for adjusting the fill light to provide different light emitting modes to meet different fill light requirements.

[0051] The dimming module 2 is disposed on the light emitting side of the light emitting module 1 , and the dimming module 2 is connected to the light emitting module 1 to shorten the propagation path of the light therebetween and reduce light loss.

[0052] The dimming module 2 includes a light control unit 21. Along the light emitting direction of the light emitting module 1, the projection of the light emitting module 1 and the projection of the light control unit 21 at least partially overlap. At the position where the projections of the light emitting module 1 and the light control unit 21 overlap, the fill light can smoothly pass through the light control unit 21, so as to adjust the fill light and obtain different fill light schemes.

[0053] The light control unit 21 has a first circuit connection state and a second circuit connection state. In the first circuit connection state, the light control unit 21 is used to allow the fill light to pass through in a collimated manner to form direct light, and provide relatively concentrated light with higher brightness for fill light; in the second circuit connection state, the light control unit 21 is used to diverge the fill light to form scattered light, and provide relatively uniform light with relatively softer brightness for fill light; in order to adapt to the fill light needs in different shooting environments, different fill light solutions are provided to improve the overall picture quality obtained by shooting.

[0054] There are four main types of existing dimming technologies, namely polymer dispersed liquid crystal (PDLC), suspended particle device (SPD), dichroic dye liquid crystal (DDLC), and electrochromism (EC). Compared with the four existing dimming technologies, the dimming module 2 in this application can effectively improve the dimming speed, dimming color and fill light, see Table 1 below for details.

[0055]

[0056]

[0057] Table 1

[0058] The present application will be described in detail below in conjunction with the above Table 1.

[0059] like Figure 1 As shown, in the electronic device provided by the present application, the light control unit 21 includes a shell 211 , a solution 212 and charged dye molecules 213 .

[0060] The shell 211 includes a first wall 2111, a second wall 2112 and a peripheral wall 2113. The first wall 2111 and the second wall 2112 are parallel to each other, and the two are opposite and spaced apart along the light-emitting direction of the light-emitting module 1. The peripheral wall 2113 is a ring-shaped frame or cylindrical structure that is through along the light-emitting direction of the light-emitting module 1. The first wall 2111 is sealed and connected to one end of the peripheral wall 2113 along the light-emitting direction, and the second wall 2112 is sealed and connected to the other end of the peripheral wall 2113 along the light-emitting direction. A closed cavity is formed by enclosing the first wall 2111, the second wall 2112 and the peripheral wall 2113.

[0061] Optionally, the peripheral wall 2113 is made of structural adhesive and is bonded and fixed to the first wall 2111 and the second wall 2112 respectively, so as to effectively ensure the sealing performance of the shell 211 .

[0062] At least one of the first wall 2111 and the second wall 2112 is an electrode plate; when powered on, the electrode plate is charged and can attract or repel charged particles.

[0063] The solution 212 is filled in the interior of the shell 211; the charged dye molecules 213 are arranged in the interior of the shell 211 and dissolved in the solution 212. Optionally, the solution 212 fills the space inside the shell 211, and in the first circuit connection state, the charged dye molecules 213 can be uniformly dissolved and distributed in the interior of the shell 211, and in the second circuit connection state, the charged dye molecules 213 can be quickly and uniformly adsorbed and laid on the surface of the electrode plate, so as to ensure that the fill light emitted to any position of the light control unit 21 can pass through the collected charged dye molecules 213, thereby realizing the adjustment of the fill light.

[0064] In the first circuit connection state, the charge carried by the charged dye molecule 213 is opposite to the charge carried by the electrode plate. By adjusting the circuit connection state of the light control unit 21, the electrode plate can adsorb the charged dye molecule 213, thereby achieving the effect of adjusting the fill light mode.

[0065] like Figures 1 to 5 As shown, in the electronic device provided by the present application, the light emitting module 1 includes a focusing element 11 , a light source 12 and a reflecting element 13 .

[0066] A light guiding groove is recessed on a surface of the focusing element 11 on one side facing the dimming module 2, the slot of the light guiding groove faces the dimming module 2, and along the direction from the slot bottom of the light guiding groove to the slot slot, the light guiding groove is gradually expanded, and the slot wall of the light guiding groove forms a first reflecting surface 111; at least a portion of the reflective element 13 is inserted into the light guiding groove from the slot, and along the direction from the slot bottom of the light guiding groove to the slot slot, the reflective element 13 is gradually expanded, and a second reflecting surface 131 is formed on a surface of the reflective element 13 facing the light guiding groove, a reflecting annulus 14 is formed between the first reflecting surface 111 and the second reflecting surface 131, and a ring-shaped light outlet is formed between the reflective element 13 and the edge of the slot of the light guiding groove.

[0067] The light source 12 is disposed at the bottom of the light guide groove. The light emitted by the light source 12 is repeatedly reflected multiple times in a zigzag shape between the first reflection surface 111 and the second reflection surface 131 in the reflection annulus 14 to change the propagation direction until it reaches the dimming module 2 from the light outlet, which is equivalent to converting the point light source 12 into a ring light source 12, effectively increasing the light emitting area and making full use of the light emitted by the light source 12.

[0068] Optionally, in the electronic device provided by the present application, the first reflective surface 111 and the second reflective surface 131 are smooth curved surfaces. Optionally, the first reflective surface 111 and the second reflective surface 131 are provided with corrugated or sawtooth reflective lines. While achieving light focusing, the collimation of the light output can also be improved, the light utilization rate is improved, and zoom adjustment becomes possible.

[0069] like Figures 1 to 5As shown, in the electronic device provided by the present application, the focusing element 11 and the dimming module 2, and the reflecting element 13 and the dimming module 2 are bonded and fixed by the bonding layer 3. The focusing element 11 and the reflecting element 13 are firmly connected to the dimming module 2, thereby shortening the propagation path of the fill light to the greatest extent, improving the light utilization rate, and reducing light loss.

[0070] Optionally, the charged dye molecules 213 may be quantum dots, organic fluorescent dyes or conventional luminescent dyes.

[0071] Alternatively, if Figure 2 and Figure 3 As shown, the electronic device provided by the present application, wherein the charged dye molecule 213 is an aggregation-induced quenching dye molecule, which is a traditional planar luminescent molecule; the aggregation-induced quenching dye molecule often exhibits strong fluorescence when dissolved in a single molecule state in the solution 212, but its luminescence weakens or even disappears after aggregation; this phenomenon is called concentration quenching effect or aggregation-induced quenching phenomenon (Aggregation Caused Quenching, ACQ).

[0072] like Figure 2 As shown, the first circuit connection state is the power-on state, the charged dye molecules 213 are adsorbed and aggregated on the surface of the electrode plate and at least partially produce the phenomenon of fluorescence aggregation-induced quenching, and the fill light is collimated through the dimming module 2 to form direct light. Specifically, the light-emitting module 1 and the dimming module 2 are powered on at the same time, and the light source 12 emits fill light, which is reflected by the first reflective surface 111 and the second reflective surface 131 and collimated and emitted from the light outlet; at the same time, the electrode plate is powered on and carries a charge, which is opposite to the polarity of the charge carried by the aggregation-induced quenching dye molecules, and the aggregation-induced quenching dye molecules are aggregated and adsorbed on the electrode plate, and the phenomenon of fluorescence aggregation-induced quenching occurs. When the fill light is irradiated, no fluorescence is emitted, and the fill light can be collimated and emitted, and the emitted fill light spot presents the characteristics of high beam, high brightness and concentrated brightness.

[0073] like Figure 3As shown, the second circuit connection state is the power-off state, the charged dye molecules 213 are dissolved in the solution 212, the supplementary light irradiates the charged dye molecules 213, and the charged dye molecules 213 emit fluorescence to form scattered light. Specifically, the light-emitting module 1 is powered on, and the light source 12 emits supplementary light; the supplementary light is reflected by the first reflective surface 111 and the second reflective surface 131 and is collimated and emitted from the light outlet; at the same time, the dimming module 2 is not powered on, the electrode plate does not carry a charge, the aggregation-induced quenching dye molecules are dissolved in the solution 212, and when the supplementary light passes through the light control unit 21, the aggregation-induced quenching dye molecules are irradiated by the supplementary light and excited to fluoresce. Since the fluorescence emitted by the aggregation-induced quenching dye molecules is scattered light, the light emitted from the entire dimming module 2 is scattered soft light, and the supplementary light spot emitted presents the characteristics of low light and uniform soft light.

[0074] like Figure 4 As shown, the electronic device provided by the present application, in the power-on state, by adjusting the power-on voltage, controlling the dispersion and aggregation concentration of the charged dye molecules 213, combined with the principle of photoluminescence of the charged dye molecules 213 by irradiation of the light source 12, realizes the adjustment of the emission direction, color and intensity of the fill light. It is conducive to realizing a soft light fill solution with variable focus (focus and light intensity at different distances) and arbitrary colors, meeting the upgrade of the soft light fill function, and providing higher brightness and integrated flash function effects compared to the existing fill light breathing lamp.

[0075] The light source 12 can be an LED, which emits blue light composed of main blue and partial green. By adjusting the power-on voltage value of the dimming module 2, different aggregation degrees of the charged dye molecules 213 can be achieved, that is, the illumination luminous intensity of the charged dye molecules 213 is controlled. By superimposing the luminous intensity of the charged dye molecules 213 and the luminous intensity of the light source 12, different light output colors of the dimming module 2 can be achieved.

[0076] In the power-on state, when the power-on voltage is the first voltage, the charged dye molecules 213 are adsorbed and aggregated on the surface of the electrode plate to generate a fluorescence aggregation-induced quenching phenomenon and do not emit fluorescence; specifically, when the dimming module 2 is powered by a high voltage, the charged dye molecules 213 are aggregated and quenched and do not emit light, and the dimming module 2 emits the blue light of the light source 12;

[0077] When the power-on voltage is the second voltage, more than half of the charged dye molecules 213 are adsorbed and aggregated on the surface of the electrode plate to produce a fluorescence aggregation-induced quenching phenomenon, and the supplementary light irradiates the charged dye molecules 213 that are not aggregated on the electrode plate and emits a first red fluorescence; specifically, when the dimming module 2 is powered by a medium voltage, a large number of charged dye molecules 213 are aggregated and quenched, and only emit weak red fluorescence when irradiated by the supplementary light, and the blue light of the light source 12 is superimposed on the weak red light to make the entire dimming module 2 emit green light;

[0078] When the power-on voltage is the third voltage, less than half of the charged dye molecules 213 are adsorbed and aggregated on the surface of the electrode plate to produce a fluorescence aggregation-induced quenching phenomenon, and the supplementary light irradiates the charged dye molecules 213 that are not aggregated on the electrode plate and emits a second red fluorescence; specifically, when the dimming module 2 is powered on at a low voltage, part of the charged dye molecules 213 are aggregated and quenched, and emit part of the red fluorescence when irradiated by the supplementary light, and the blue light of the light source 12 is superimposed on part of the red light to make the entire dimming module 2 emit yellow light or white light;

[0079] In the power-off state, all the charged dye molecules 213 are dissolved in the solution 212, and the supplementary light illuminates the charged dye molecules 213 and emits a third red fluorescence; specifically, when the dimming module 2 is not powered, the charged dye molecules 213 do not aggregate, but are evenly dissolved in the solvent, and emit strong red fluorescence when illuminated by the supplementary light. The red fluorescence covers the blue light of the light source 12, causing the entire dimming module 2 to emit red light.

[0080] Specifically, the first voltage is greater than the second voltage, the second voltage is greater than the third voltage, the first voltage is a high voltage, the second voltage is a medium voltage, and the third voltage is a low voltage. It should be noted that the voltage value ranges of the first voltage, the second voltage, and the third voltage can be based on the charged dye molecules 213, and the specific value range is based on ensuring that different colors of light can be emitted according to the above scheme.

[0081] The intensity value of the first red fluorescence is smaller than the intensity value of the second red fluorescence, and the intensity value of the second red fluorescence is smaller than the intensity value of the third red fluorescence, so as to achieve a transitional change in color.

[0082] like Figure 5 and Figure 6 As shown, the electronic device provided by the present application, wherein the charged dye molecule 213 is an aggregation-induced emission dye molecule, which is an organic fluorescent molecule, which hardly emits light after being dissolved into a single molecule in the solution 212, and has a greatly enhanced luminescence ability in the condensed form (forming an aggregate or solid state). This phenomenon is called aggregation-induced emission (AIE).

[0083] like Figure 5 As shown, the first circuit connection state is the power-off state, the charged dye molecules 213 are dissolved in the solution 212, and the fill light rays are collimated through the dimming module 2 to form direct light. Specifically, the light emitting module 1 is powered on, and the light source 12 emits fill light rays; the fill light rays are reflected by the first reflecting surface 111 and the second reflecting surface 131 and collimatedly emitted from the light outlet; at the same time, the dimming module 2 is not powered on, the electrode plate does not carry a charge, the aggregation-induced luminescence dye molecules are dissolved in the solution 212, and when the fill light rays are irradiated, no fluorescence is emitted, and the fill light rays can be collimated and emitted fill light spots present the characteristics of high beam, high brightness and concentrated brightness.

[0084] like Figure 6 As shown, the second circuit connection state is the power-on state, the charged dye molecules 213 are adsorbed and aggregated on the surface of the electrode plate and generate a fluorescence aggregation-induced luminescence phenomenon, the supplementary light irradiates the charged dye molecules 213 and the charged dye molecules 213 emit fluorescence. Specifically, the light-emitting module 1 and the dimming module 2 are powered on at the same time, the light source 12 emits supplementary light, the supplementary light is reflected by the first reflection surface 111 and the second reflection surface 131 and collimated and emitted from the light outlet; at the same time, the electrode plate is powered on and carries a charge, which is opposite to the polarity of the charge carried by the aggregation-induced luminescence dye molecules, and the aggregation-induced luminescence dye molecules are aggregated and adsorbed on the electrode plate, and the fluorescence aggregation-induced luminescence phenomenon occurs. When the supplementary light passes through the light control unit 21, the aggregation-induced luminescence dye molecules are irradiated by the supplementary light and excited to emit fluorescence. Since the fluorescence emitted by the aggregation-induced luminescence dye molecules is scattered light, the light emitted from the entire dimming module 2 is scattered soft light, and the supplementary light spot emitted presents the characteristics of low light and uniform soft light.

[0085] Optionally, in the electronic device provided by the present application, the solution 212 is a homogenizing solvent for promoting uniform dissolution and diffusion of charged dye molecules, such as water and ethanol, etc., and the solution 212 contains neutralizing ions 214, and the charge carried by the neutralizing ions 214 is opposite to the charge carried by the charged dye molecules 213; the charge carried by the neutralizing ions 214 and the charge carried by the charged dye molecules 213 offset each other, so that the housing 211 is neutral as a whole. The use of a homogenizing solvent has the advantages of good dissolution effect and low cost.

[0086] The neutralizing ions 214 are colorless and transparent ions, which can allow the fill light to pass through, thereby preventing the setting of the neutralizing ions 214 from affecting the propagation of light and ensuring the dimming effect of the fill light.

[0087] Optionally, in an embodiment of the present application, the first wall 2111 is a first electrode plate, and the second wall 2112 is a second electrode plate. When powered on, the first electrode plate and the second electrode plate have opposite polarities, and the first electrode plate and the charged dye molecule 213 have opposite polarities. The first electrode plate is used to adsorb the charged dye molecule 213; the second electrode plate and the neutralizing ion 214 have opposite polarities, and the second electrode plate is used to adsorb the neutralizing ion 214.

[0088] Optionally, the distance between the first wall 2111 and the light emitting module 1 is smaller than the distance between the second wall 2112 and the light emitting module 1. That is, the first wall 2111 is arranged close to the light emitting module 1, which can effectively reduce the distance between the fill light from the light outlet to the charged dye molecules 213 gathered on the first electrode plate, thereby improving the light utilization rate.

[0089] In some embodiments of the present application, the good solvent of the solution 212 may also be an insulating electrophoretic solution. In this case, only one electrode plate is needed, and there is no need to set the neutralizing ion 214, which can further reduce the processing difficulty and cost of the dimming module 2.

[0090] like Figures 1 to 5 As shown, the electronic device provided by the present application, wherein the light control unit 21 also includes a first transparent substrate 22 and a second transparent substrate 23, the first transparent substrate 22 covers and is connected to the first wall 2111, the second transparent substrate 23 covers and is connected to the second wall 2112, and the light emitting module 1 is connected to the side of the first transparent substrate 22 away from the first wall 2111. The first transparent substrate 22 and the second transparent substrate 23 can effectively provide protection for the dimming module 2 to prevent the first electrode plate and the second electrode plate from being scratched. At the same time, the first transparent substrate 22 and the second transparent substrate 23 cooperate with the peripheral wall 2113 of the dimming module 2 to insulate the first electrode plate and the second electrode plate to prevent leakage, short circuit and the like. Optionally,

[0091] The first transparent substrate 22 and the second transparent substrate 23 can be made of various materials such as glass, polyethylene terephthalate (PET), polyimide (PI), etc., and have good light transmittance to ensure that the supplementary light can pass through smoothly.

[0092] The electronic device provided in the present application includes a light-emitting module 1 and a dimming module 2 which are arranged relatively to each other. The fill light emitted by the light-emitting module 1 can be emitted through the dimming module 2. By setting a light control unit 21 in the dimming module 2, and making the light control unit 21 have a first circuit connection state and a second circuit connection state, in the first circuit connection state, the dimming module 2 cooperates with the light-emitting module 1 to emit direct light, providing more concentrated light with higher brightness for fill light. In the second circuit connection state, the dimming module 2 cooperates with the light-emitting module 1 to emit scattered light, providing more uniform light with softer brightness for fill light, so as to adapt to the fill light needs in different shooting environments and provide different fill light schemes to improve the overall picture quality obtained by shooting.
