Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a lighting module, a camera module, and an electronic device. Background Technology

[0002] Currently, electrochromic components are attached to the surface of ordinary flash units using double-sided adhesive. Light enters the electrochromic component through the reflective area to achieve different lighting effects. In related technologies, the electrochromic component and the flash unit are powered by separate power supplies, which occupies a large amount of space inside the electronic device. Furthermore, the space occupied by the flash unit in current electronic devices is usually extremely limited. Therefore, this setup compresses the trace width of the electrochromic component, thereby increasing the resistance of the trace and thus increasing the energy consumption of the circuit board for signal transmission. Utility Model Content

[0003] This application aims to provide a lighting module, a camera module, and an electronic device, which at least solves one of the problems of the lighting module occupying a large space and increasing energy consumption within the electronic device.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application propose a lighting module, comprising: a power supply component; a light-emitting element, the light-emitting element being conductively connected to the power supply component; an electrochromic component, the electrochromic component being disposed on the light-emitting side of the light-emitting element; and a conductive element, one end of the conductive element being conductively connected to the electrochromic component, and the other end of the conductive element being conductively connected to the power supply component through the light-emitting element, so that the power supply component supplies power to the light-emitting element and the electrochromic component; wherein, the light emitted by the light-emitting element can pass through the electrochromic component, and the light transmittance of the electrochromic component can be adjusted according to the voltage value of the electrochromic component.

[0006] Secondly, embodiments of this application provide a camera module, including: a camera; and a lighting module as described in any of the first aspects.

[0007] Thirdly, embodiments of this application provide an electronic device, including: a lighting module as described in any of the first aspects; or a camera module as described in the second aspect.

[0008] In the embodiments of this application, the lighting module includes a power supply component, a light-emitting element, a conductive element, and an electrochromic component. The light-emitting element is conductively connected to the power supply component, enabling the power supply component to supply power to the light-emitting element. The electrochromic component is disposed on the light-emitting side of the light-emitting element, and the transmittance of the electrochromic component can be adjusted according to the voltage value of the electrochromic component, thereby allowing the light emitted by the light-emitting element to be adjusted. This allows the lighting module to achieve high-brightness supplementary lighting when the transmittance of the electrochromic component is high, and to achieve haze supplementary lighting when the transmittance of the electrochromic component is low. Furthermore, one end of the conductive element is conductively connected to the electrochromic component, and the other end of the conductive element is conductively connected to the power supply component through the light-emitting element. This allows a single power supply component to supply power to both the light-emitting element and the electrochromic component simultaneously. That is, there is no need to set up a separate circuit board and power supply for the electrochromic component, thereby reducing the number of circuit boards and power supplies, lowering manufacturing costs, reducing the power consumption caused by setting up a separate circuit board and power supply, and reducing the overall space occupied by the lighting module in the thickness direction of the electronic device, achieving a thinner and lighter design of the electronic device.

[0024] The following is combined with Figures 1-7 This application describes a lighting module, a camera module, and an electronic device according to embodiments thereof.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the lighting module includes: a power supply component 1; a light-emitting element 2, which is conductively connected to the power supply component 1; an electrochromic component 3, which is disposed on the light-emitting side of the light-emitting element 2; and a conductive element 4, one end of which is conductively connected to the electrochromic component 3, and the other end of which is conductively connected to the power supply component 1 through the light-emitting element 2, so that the power supply component 1 supplies power to the light-emitting element 2 and the electrochromic component 3; wherein, the light emitted by the light-emitting element 2 can pass through the electrochromic component 3, and the light transmittance of the electrochromic component 3 can be adjusted according to the voltage value of the electrochromic component 3.

[0026] In the embodiments of this application, the lighting module includes a power supply component 1, a light-emitting element 2, a conductive element 4, and an electrochromic component 3. The light-emitting element 2 is electrically connected to the power supply component 1, so that the power supply component 1 can supply power to the light-emitting element 2. The electrochromic component 3 is disposed on the light-emitting side of the light-emitting element 2, and the transmittance of the electrochromic component 3 can be adjusted according to the voltage value of the electrochromic component 3, thereby allowing the light emitted by the light-emitting element 2 to be adjusted. This enables the lighting module to achieve high-brightness supplementary lighting when the transmittance of the electrochromic component 3 is high, and to achieve haze supplementary lighting when the transmittance of the electrochromic component 3 is low. Furthermore, one end of the conductive component 4 is conductively connected to the electrochromic component 3, and the other end of the conductive component 4 is conductively connected to the power supply component 1 through the light-emitting component 2, so that one power supply component 1 can simultaneously supply power to the light-emitting component 2 and the electrochromic component 3. That is, there is no need to set up a separate circuit board 12 and power supply 10 for the electrochromic component 3, thereby reducing the number of circuit boards 12 and power supply 10, reducing manufacturing costs, reducing the power consumption caused by setting up a separate circuit board 12 and power supply 10, and reducing the overall space occupied by the light module in the thickness direction of the electronic device, thus realizing the thin and light design of the electronic device.

[0027] It should be noted that when the voltage value of the electrochromic component 3 is high, the light transmittance of the electrochromic component 3 is high; when the voltage value of the electrochromic component 3 is low, the light transmittance of the electrochromic component 3 is low. The electrochromic component 3 exhibits a reversible change in its color / transmittance under the influence of an external electric field.

[0028] Optionally, the light-emitting element 2 is a flash.

[0029] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, according to some embodiments of this application, optionally, the light-emitting element 2 includes: a housing 20, the housing 20 having a conductive area 202 and a reflective area 204, the conductive area 202 being connected to the power supply component 1, the electrochromic component 3 being disposed on one side of the housing 20, and the conductive element 4 being electrically connected to the conductive area 202; and a light source 22, the light source 22 being connected to the power supply component 1, the light emitted by the light source 22 being reflected by the reflective area 204 to the electrochromic component 3.

[0030] In this embodiment, the light-emitting element 2 includes a housing 20 and a light source 22. The housing 20 is provided with a conductive area 202 and a reflective area 204. The conductive area 202 is connected to the power supply component 1, and the conductive element 4 is electrically connected to the conductive area 202, thereby enabling the electrochromic component 3 to be electrically connected to the power supply component 1, so that the power supply component 1 can supply power to the electrochromic component 3. The light source 22 is connected to the power supply component 1, and the light emitted by the light source 22 is reflected by the reflective area 204 to the electrochromic component 3, and then emitted after passing through the electrochromic component 3.

[0031] Optionally, the lamp source 22 and the conductive area 202 are connected to the power supply component 1 through the same connection structure. Alternatively, the conductive area 202 is directly connected to the power supply component 1 through a separate connection structure, and the lamp source 22 is connected to the power supply component 1 through another connection structure.

[0032] Optionally, the light source 22 includes LED (Light Emitting Diode) beads.

[0033] Optionally, the reflective area 204 of the housing 20 surrounds the conductive area 202.

[0034] Optionally, the electrochromic component 3 is located on one side of the housing 20, and the light source 22 is located on the other side of the housing 20.

[0035] Optionally, Figure 4 and Figure 5 The arrow in the image indicates the direction of the light.

[0036] like Figure 3 As shown, according to some embodiments of this application, optionally, the light-emitting element 2 further includes: a connector 24, the light source 22 is connected to the conductive area 202 through the connector 24, the power supply component 1 includes a power supply 10 and a circuit board 12 connected to each other, and the connector 24 is connected to the circuit board 12.

[0037] In this embodiment, the light-emitting element 2 further includes a connector 24. The light source 22 is connected to the conductive area 202 through the connector 24. Simultaneously, the connector 24 is connected to the circuit board 12 of the power supply component 1. This allows the connector 24 to achieve both electrical connection between the light source 22 and the circuit board 12, and electrical connection between the conductive area 202 and the circuit board 12 of the power supply component 1, reducing the number of connection structures and lowering manufacturing costs. Furthermore, the installation of the light source 22 simultaneously establishes conductivity between the conductive area 202 and the power supply component 1, significantly reducing the assembly difficulty of the light-emitting element 2.

[0038] Optionally, connector 24 includes conductive adhesive 40.

[0039] Optionally, the bottom of the housing 20 is provided with an opening, and the area around the opening is a conductive area 202. The light source 22 is bonded to the first side of the conductive adhesive 40, and a part of the second side of the conductive adhesive 40 is bonded to the conductive area 202 inside the housing 20. The other part of the second side of the conductive adhesive 40 is bonded to the circuit board 12 through the opening, thereby realizing the electrical connection between the light source 22 and the conductive area 202 and the circuit board 12. The electrochromic component 3 is connected to the conductive area 202, thus realizing the electrical connection between the electrochromic component 3 and the circuit board 12 of the power supply component 1, and realizing the power supply to the electrochromic component 3.

[0040] like Figure 3 As shown, according to some embodiments of this application, optionally, the conductive region 202 includes a metal plating layer 2020, and the other end of the conductive element 4 is connected to the metal plating layer 2020.

[0041] In this embodiment, the conductive area 202 includes a metal plating layer 2020, which has conductive properties. Therefore, by connecting one end of the conductive element 4 to the electrochromic component 3 and the other end to the metal plating layer 2020, the electrical connection strength between the electrochromic component 3 and the power supply component 1 can be improved.

[0042] Optionally, the metal plating 2020 includes a silver-plated surface, a gold-plated surface, and a copper-plated surface.

[0043] According to some embodiments of this application, the conductive element 4 may optionally include at least one of conductive adhesive 40, probe 42, and spring sheet.

[0044] In this embodiment, such as Figure 4 As shown, the conductive component 4 can be conductive adhesive 40, with the electrochromic component 3 and the conductive area 202 bonded to its two ends respectively, making assembly relatively convenient. Figure 5As shown, the conductive element 4 can also be a probe 42. Compared to the conductive adhesive 40, the probe 42 is non-flowable, has lower cost, and higher reliability. Alternatively, the conductive element 4 can be a spring sheet. The spring sheet has a certain degree of elasticity, enabling fine-tuning of the position between the electrochromic component 3 and the conductive area 202, thereby preventing the electrochromic component 3 or the housing 20 from breaking under external stress.

[0045] like Figure 7 As shown, according to some embodiments of this application, optionally, the electrochromic component 3 includes: a liquid crystal layer 32; a first electrode layer 30 and a second electrode layer 31, wherein the first electrode layer 30, the liquid crystal layer 32 and the second electrode layer 31 are stacked sequentially, the first electrode layer 30 is disposed on the side of the liquid crystal layer 32 near the light-emitting element 2 and is connected to the conductive element 4; a first encapsulation layer 34 is disposed on the side of the first electrode layer 30 away from the liquid crystal layer 32; and a second encapsulation layer 36 is disposed on the side of the second electrode layer 31 away from the liquid crystal layer 32.

[0046] In this embodiment, the electrochromic component 3 includes a first electrode layer 30, a second electrode layer 31, a liquid crystal layer 32, a first encapsulation layer 34, and a second encapsulation layer 36. The first electrode layer 30 is located on the side of the liquid crystal layer 32 closest to the light-emitting element 2 and is connected to the conductive element 4, so that when the first electrode layer 30 is energized, there is a voltage difference between it and the second electrode layer 31, thus forming a unidirectional voltage electric field, causing the liquid crystal layer 32 to change and thereby adjusting the light transmittance. At the same time, connecting the first electrode layer 30 to the conductive area 202 can also reduce the length of the conductive element 4, facilitate the connection between the electrochromic component 3 and the conductive area 202, reduce costs, and facilitate assembly. The first encapsulation layer 34 and the second encapsulation layer 36 are respectively disposed outside the first electrode layer 30 and the second electrode layer 31, and are used to encapsulate the first electrode layer 30, the liquid crystal layer 32, and the second electrode layer 31, making the electrochromic component 3 a component and improving the resistance to damage of the electrochromic component 3.

[0047] According to some embodiments of this application, optionally, the lighting module further includes: a control component connected to the power supply component 1 and the electrochromic component 3, used to adjust the voltage value of the electrochromic component 3 to adjust the light transmittance of the electrochromic component 3.

[0048] In this embodiment, the lighting module also includes a control component, which is connected to the power supply component 1 and the electrochromic component 3. The control component is used to adjust the voltage value of the electrochromic component 3, thereby making the voltage value of the electrochromic component 3 adjustable within a certain range. That is, the voltage value of the electrochromic component 3 can be adjusted in multiple levels according to the actual situation. Under the action of the electrochromic component 3, the light output haze of the lighting module has multiple adjustable modes, which means that the lighting module has multiple light output modes and achieves the function of adjustable supplementary lighting effect.

[0049] Optionally, when powered on, the transmittance of the electrochromic component 3 reaches over 92%, and when paired with the light source 22, it achieves the function of a conventional flash; when powered off, the transmittance of the electrochromic component 3 is about 25%, and when paired with the light source 22, it achieves the effect of haze fill light; by controlling the value of the intermediate voltage, the transmittance of the electrochromic component 3 can be changed within the range of 25%-92%.

[0050] According to some embodiments of this application, optionally, the lighting module further includes: a photosensitive sensor, electrically connected to the power supply component 1 and the control component, for detecting the light intensity of the environment in which the lighting module is located, and the control component adjusting the voltage value of the electrochromic component 3 according to the detection value of the photosensitive sensor.

[0051] In this embodiment, a photosensitive sensor is used to detect the light intensity of the tube in which the light module is located. In this way, with the cooperation of the photosensitive sensor, the voltage value of the electrochromic component 3 can be adjusted to better suit the environment in which the light module is located, thereby realizing different stepped supplementary lighting functions under different ambient light conditions, which can further improve the user's perception.

[0052] Optionally, the photosensitive sensor can be placed on the housing of the electronic device to which the lighting module is applied, on the camera module, or in other locations, as long as it can sense the ambient light of the scene to which the lighting module is applied.

[0053] like Figure 6 As shown, according to some embodiments of this application, optionally, the reflective area 204 includes a first reflective area 2040 and a second reflective area 2042, the first reflective area 2040 surrounding the second reflective area 2042, wherein the reflectivity of the first reflective area 2040 is greater than the reflectivity of the second reflective area 2042.

[0054] In this embodiment, the reflective area 204 includes a first reflective area 2040 and a second reflective area 2042. The reflectivity of the first reflective area 2040 is different from that of the second reflective area 2042, which allows the first reflective area 2040 to reflect more light to increase the intensity of the light. The second reflective area 2042 can make the light more uniform and softer, avoiding glare.

[0055] Optionally, the surface of the first reflective area 2040 is smoother than the surface of the second reflective area 2042; that is, the surface of the first reflective area 2040 is relatively smooth, while the surface of the second reflective area 2042 is relatively rough. Optionally, the reflective area 204 is disposed around the conductive area 202. Of course, the reflective area 204 and the conductive area 202 may also have different positional relationships, which is not limited here.

[0056] Alternatively, the reflective area 204 may have only one type of surface structure, such as glossy or matte, or it may have a combination of three or more surface structures.

[0057] According to one embodiment of this application, a camera module is provided, comprising: a camera; and a lighting module as described in any of the preceding claims.

[0058] According to one embodiment of this application, an electronic device is proposed, comprising: a lighting module as proposed in any of the above embodiments; or a camera module as proposed in the above embodiments.

[0059] According to some embodiments of this application, the lighting module proposed in this application eliminates the FPC (Flexible Printed Circuit) design of the electrochromic component 3, which can reduce the impact of the PDLC (polymer dispersed liquid crystal) component on the spatial structure, contributing at least 0.13mm (double-layer FPC) to the overall space, and reducing the height of the camera bump. It can also reduce the wiring loss caused by FPC transmission, instead directly utilizing the flash (e.g., the light-emitting element 2) to provide power to the 10, which is expected to reduce power consumption by 0.5mW. Furthermore, it saves an entire power supply module, achieving the goal of cost savings.

[0060] This application provides a solution that reduces power consumption while achieving flexible supplemental lighting functionality for PDLC components. The system is divided into blocks based on the function of the flash, such as... Figure 6 As shown, the center of the flash is a four-lobed LED. When powered on, the LED emits light onto the back of the PDLC through the matte area (e.g., the second reflective area 2042) / glossy area (e.g., the first reflective area 2040).

[0061] In the case of a ring-shaped flash, light is emitted only through the central ring-shaped area. Therefore, this application utilizes the ineffective light-emitting area to increase conductivity (e.g., conductive double-sided tape) and connect it with the silver-plated area of ​​the flash, thereby realizing a shared power supply 10 for the PDLC and flash. This eliminates the power consumption of the PDLC line group caused by power supply and reduces the line loss of the PDLC. In addition, because this solution eliminates the PDLC FPC, the overall thickness of the PDLC + flash assembly is reduced by 0.14mm, that is, the lens boss of the entire device is lowered by 0.14mm.

[0062] As can be seen from the structure of PDLC, in related technologies, the PDLC's FPC is connected to the upper and lower electrode layers through anisotropic conductive film (ACF). (The PDLC's FPC has two metal electrodes, one on the left and one on the right. The left electrode connects to the lower electrode layer to form a lower electric field, and the right electrode connects to the upper electrode layer to form an upper electric field, which together provide a capacitive field effect for the middle liquid crystal layer 32.) In this application, the PDLC's FPC is eliminated, and the bidirectional voltage electric field is changed to a unidirectional voltage electric field, that is, the first electrode layer 30 is connected to the power supply 10.

[0063] Optionally, the first electrode layer 30 and the power supply 10 can be connected by using an ACF conductive adhesive (e.g., conductive adhesive 40). The first electrode layer 30 contacts the metal of the silver-plated area through the ACF, thereby forming a unidirectional voltage electric field. The ACF can be the same material as the bonding material, without any special requirements. In this case, the PDLC component can be controlled by controlling the voltage applied to the silver-plated area, thereby realizing the function of adjusting the voltage value of the electrochromic component 3.

[0064] Alternatively, since ACF has strict requirements for environmental factors and the adhesive is fluid, achieving conductivity through conductive adhesive 40 may require significant resources to improve process conditions, resulting in higher costs. Therefore, the following improvements are made: Since the voltage field required to activate PDLC is low, this function can be achieved through contact with probe 42 at extremely low cost; at the same time, probe 42 is a metal structure with excellent reliability, which greatly improves environmental testing capabilities.

[0065] This application significantly improves upon the increased power consumption and larger overall size issues associated with PDLC modules. Furthermore, the materials used are mature and readily available, resulting in simple and low-cost implementation while ensuring reliability. Optionally, it can be integrated with a photosensor function, using the photosensor to adjust the voltage of the PDLC module and achieve different stepped supplementary lighting functions under varying ambient light conditions, further enhancing the user experience.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0067] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
