Description

Technical Field

[0001] This application relates to the field of mobile phone accessory technology, and in particular to a mobile phone flashlight focusing accessory. Background Technology

[0002] Currently, every camera phone is equipped with a flash to supplement light when there is insufficient light, improving the quality of photos. This flash also functions as a flashlight. In dark environments, users can turn on the phone's flashlight function, which will then remain constantly lit for illumination.

[0003] Although both are used as light sources, "flashlights" and "flashlights" have different requirements for their light source characteristics. Flashlights provide supplemental lighting for photographs, and to prevent color distortion in the image, the light emitted by the flashlight must be omnidirectional and diffused, with the intensity as uniform as possible in all directions. Flashlights, on the other hand, require a certain direction of light, ideally forming a beam. The light from the source should be focused in as uniform a direction as possible to enhance the illumination distance and brightness. These two different uses dictate different requirements for the light source; these are contradictory requirements, and the same light source cannot simultaneously meet both needs.

[0004] Currently, mobile phone light sources primarily function as flashlights, emitting diffused light. Therefore, when used as a flashlight, the diffused light has a very short illumination distance, with an effective illumination range of only 1-2 meters in darkness, resulting in poor performance.

[0058] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is only for explaining specific embodiments and is not intended to limit the application. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0059] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] It should be noted that the directional terms appearing in this invention are based on the relative positional relationships shown in the accompanying drawings and should not be taken as absolute limitations on this application.

[0061] refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a mobile phone flash focusing accessory on a mobile phone according to an embodiment of the present invention. (Refer to...) Figure 2 , Figure 2 This is a schematic diagram of another mobile phone flash focusing accessory provided in an embodiment of the present invention on a mobile phone. The mobile phone flash focusing accessory provided in this embodiment of the present invention is installed on a first surface 11 of the mobile phone, and a flash lamp 12 is provided on the first surface 11; the mobile phone flash focusing accessory includes: N convex lenses 13, where N≥1, and N is a positive integer.

[0062] like Figure 1 (a) and Figure 2 As shown in (a), when the flash 12 is used as the light source of a flashlight, the orthogonal projection of one of the N convex lenses 13 covers the flash 12.

[0063] like Figure 1 (b) and Figure 2 As shown in (b), when the flash lamp 12 is used as the light source for photography, the orthographic projection of any one of the N convex lenses 13 does not overlap with the flash lamp 12.

[0064] Specifically, in this embodiment of the invention, the first surface 11 of the mobile phone can be understood as the back of the mobile phone. When the mobile phone is equipped with a mobile phone case, the mobile phone flash focusing accessory is installed on the back of the mobile phone case. As an accessory, the mobile phone flash focusing accessory is installed in a detachable manner to facilitate independent replacement or repair of the mobile phone flash focusing accessory.

[0065] like Figure 1 (a) and Figure 2As shown in (a), the convex lens 13 is located in front of the flash lamp 12. Utilizing the light-focusing characteristics of the convex lens 13, it transforms the light emitted by the flash lamp 12 into a concentrated beam, forming a beam of light, increasing brightness and illumination distance, thereby improving the lighting effect of the flash lamp 12 when used as a flashlight; as shown in (a). Figure 1 (b) and Figure 2 As shown in (b), when the flash 12 is used as the light source for photography, the orthographic projection of any one of the N convex lenses 13 does not overlap with the flash 12. At this time, the convex lens 13 moves away from the front of the flash 12, and the light emitted by the flash 12 is scattered, which does not affect the photographic effect.

[0066] In an optional embodiment of the present invention, reference is made to... Figure 3 , Figure 3 This is a schematic diagram of the structure of another mobile phone flash focusing accessory provided in an embodiment of the present invention on a mobile phone. The mobile phone flash focusing accessory provided in this embodiment of the present invention further includes: a strip shaft 14 located on one side of the flash 12, the length extension direction of the strip shaft 14 being parallel to the first surface 11; a convex lens 13 fixed on the strip shaft 14, the strip shaft 14 including a first rotation state, a second rotation state, and a third rotation state.

[0067] In the first rotation state, the orthographic projection of the convex lens 13 does not overlap with the flash lamp 12, and the plane where the convex lens 13 is located is parallel to the first surface 11.

[0068] In the second rotation state, the orthographic projection of the convex lens 13 does not overlap with the flash lamp 12, and the plane where the convex lens 13 is located is perpendicular to the first surface 11.

[0069] In the third rotation state, the orthogonal projection of the convex lens 13 covers the flash lamp 12.

[0070] Specifically, in this embodiment of the invention, N=1 is used as an example, that is, a convex lens 13 is fixedly mounted on the bar-shaped shaft 14. Figure 3 As shown in (a), the bar axis 14 is in its first rotating state, the convex lens 13 is located to the right of the bar axis 14 and is in an idle state, and the flash lamp 12 can be used as a light source for photography; as Figure 3 As shown in (b), the bar axis 14 is in the second rotation state, and the convex lens 13 is tilted to the center of the bar axis 14, forming a 90° angle with the first surface 11, acting as a support. When the user watches videos or reads the screen, the phone is placed flat, and the support will tilt the phone at an angle, making it easier for the user to view the screen; Figure 3As shown in (c), the bar axis 14 is in the third rotation state, and the convex lens 13 is moved to the left side of the bar axis 14, so that the convex lens 13 is in front of the flash lamp 12. By utilizing the light-gathering characteristics of the convex lens 13, the light emitted by the flash lamp 12 is transformed into a concentrated beam, which is in the shape of a light column, increasing the brightness and illumination distance, thereby improving the lighting effect of the flash lamp 12 when used as a flashlight.

[0071] Understandable, Figure 3 The rotating mechanism of the mobile phone flash focusing accessory shown is similar to that of a 180° hinge, allowing for 180° rotation to adjust the position of the convex lens 13.

[0072] In an optional embodiment of the present invention, reference is made to... Figure 4 , Figure 4 This is a schematic diagram of the structure of another mobile phone flash focusing accessory provided in an embodiment of the present invention on a mobile phone, with reference to... Figure 5 , Figure 5 This is a schematic diagram of the structure of another mobile phone flash focusing accessory provided in an embodiment of the present invention on a mobile phone. The mobile phone flash focusing accessory provided in this embodiment of the present invention also includes: a rotating bracket located on one side of the flash 12.

[0073] The rotating support includes a rotation center 15 and M extensions 16 extending outward from the rotation center 15; M ≥ N, and M is a positive integer.

[0074] The convex lens 13 is fixed to one end of the extension 16 away from the rotation center 15.

[0075] Specifically, in the embodiments of the present invention, such as Figure 4 As shown, the rotating bracket includes an extension 16, and a convex lens 13 is fixed at one end of the extension 16 away from the rotation center 15. That is, the example is given with M=1 and N=1. Figure 4 The mobile phone flash focusing accessory shown rotates around the central axis 15, as follows: Figure 4 As shown in (a) and (b), when the flash 12 is used as the light source for photography, the orthographic projection of the convex lens 13 does not overlap with the flash 12. At this time, the convex lens 13 moves away from the front of the flash 12, and the light emitted by the flash 12 is scattered, which does not affect the photographic effect; Figure 4 As shown in (c), when the flash lamp 12 is used as the light source of the flash lamp 12, the convex lens 13 is located in front of the flash lamp 12. The convex lens 13 utilizes the light-gathering characteristics of the light to convert the light emitted by the flash lamp 12 into a concentrated beam, which is in the shape of a light column, increasing the brightness and illumination distance, thereby improving the lighting effect of the flash lamp 12 when it is used as a flash lamp.

[0076] like Figure 5As shown, the rotating bracket includes three extensions 16, with a convex lens 13 fixed to the end of two of the extensions 16 away from the rotation center 15, while the remaining extension 16 does not have a convex lens fixed to its end away from the rotation center 15. Figure 5 The diagram in the middle is labeled 17, which is an example of M=3 and N=2. Figure 5 The mobile phone flash focusing accessory shown rotates around the central axis 15, as follows: Figure 5 As shown in (a), when the flash 12 is used as the light source for photography, the orthographic projection of the convex lens 13 does not overlap with the flash 12. At this time, the convex lens 13 moves away from the front of the flash 12, and the light emitted by the flash 12 is scattered, which does not affect the photographic effect; Figure 5 As shown in (b) and (c), when the flash lamp 12 is used as the light source of the flash lamp 12, the convex lens 13 is located in front of the flash lamp 12. The convex lens 13 utilizes the light-gathering characteristics of the light to convert the light emitted by the flash lamp 12 into a concentrated beam, which is in the shape of a light column, increasing the brightness and illumination distance, thereby improving the lighting effect of the flash lamp 12 when used as a flash lamp.

[0077] Wherein, when N≥2, the curvatures of any two convex lenses 13 are different; for example, as shown in... Figure 5 As shown, the system includes a first convex lens 131 and a second convex lens 132. The curvature of the first convex lens 131 is different from that of the second convex lens 132. Using convex lenses 13 with different curvatures in different applications, positioned in front of the flashlight 12, can adapt to more usage scenarios. Specifically, the convex lens 13 with a smaller curvature illuminates at a longer distance and is used for general lighting; the convex lens 13 with a larger curvature illuminates at a shorter distance and has better light focusing, and is used as a high-powered flashlight.

[0078] Optionally, when the convex lens 13 is a colored convex lens, when N≥2, any two of the convex lenses 13 are of different colors, filtering the light emitted by the flash lamp 12 into colored light to improve the atmosphere effect in the lighting scene.

[0079] Optionally, when patterns or text are etched on the convex lens 13, if N≥2, the patterns and / or text on any two of the convex lenses 13 are different, so as to achieve diversified information display and improve the atmosphere effect in the lighting scene.

[0080] It should be noted that, Figure 4 and Figure 5 The length of the rotation axis extends perpendicularly to the first surface 11.

[0081] In an optional embodiment of the present invention, reference is made to... Figure 6 , Figure 6This is a schematic diagram of the structure of another mobile phone flash focusing accessory provided in an embodiment of the present invention on a mobile phone. The mobile phone flash focusing accessory provided in this embodiment of the present invention further includes: a first fixing bracket 18 and a second fixing bracket 19 located on the first surface 11.

[0082] like Figure 6 As shown in (a), when the flash 12 is used as a light source for photography, the convex lens 13 is mounted on the first fixed bracket 18.

[0083] like Figure 6 As shown in (b), when the flashlight 12 is used as the light source of the flashlight, the convex lens 13 is mounted on the second fixed bracket 19.

[0084] Specifically, in this embodiment of the invention, N=3 is used as an example, and three first fixed supports 18 are used as an example. Each first fixed support 18 is equipped with a convex lens 13, such as... Figure 6 As shown, it includes three convex lenses 13, namely convex lens 133, convex lens 134 and convex lens 135, which are respectively mounted on three first fixed brackets 18; as Figure 6 As shown in (a), when the flash 12 is used as the light source for photography, the convex lens 13 is mounted on the first fixed bracket 18. The orthographic projection of the convex lens 13 does not overlap with the flash 12. At this time, the convex lens 13 is away from the front of the flash 12, and the light emitted by the flash 12 is scattered, which does not affect the photographic effect; Figure 6 As shown in (b), when the flash 12 is used as the light source of a flashlight, the convex lens on the first fixed bracket 18 can be removed and inserted into the second fixed bracket 19, so that the convex lens 13 is located in front of the flash 12. By utilizing the light-gathering characteristics of the convex lens 13, the light emitted by the flash 12 is converted into a concentrated beam, which is in the shape of a light column, increasing the brightness and illumination distance, thereby improving the lighting effect of the flash 12 when used as a flashlight.

[0085] Similarly, when N≥2, the curvatures of any two convex lenses 13 are different; for example, such as Figure 6 As shown, the system includes three convex lenses 13, any two of which have different curvatures. Using convex lenses 13 with different curvatures positioned in front of the flashlight 12 in different applications allows for greater adaptability to various usage scenarios. Specifically, the convex lens 13 with a smaller curvature illuminates at a longer distance and is used for general lighting; the convex lens 13 with a larger curvature illuminates at a shorter distance and has better light focusing, making it suitable for use as a high-powered flashlight.

[0086] Optionally, when the convex lens 13 is a colored convex lens, when N≥2, any two of the convex lenses 13 are of different colors, filtering the light emitted by the flash lamp 12 into colored light to improve the atmosphere effect in the lighting scene.

[0087] Optionally, when patterns or text are etched on the convex lens 13, if N≥2, the patterns and / or text on any two of the convex lenses 13 are different, so as to achieve diversified information display and improve the atmosphere effect in the lighting scene.

[0088] In an optional embodiment of the present invention, reference is made to... Figure 7 , Figure 7 This is a schematic diagram of the structure of another mobile phone flash focusing accessory on a mobile phone according to an embodiment of the present invention; see reference. Figure 8 , Figure 8 A method provided by an embodiment of the present invention Figure 7 An enlarged schematic diagram of a mobile phone flash focusing accessory. The mobile phone flash focusing accessory provided in this embodiment of the invention further includes: a strip bracket 20; in a first direction X, the strip bracket 20 includes a first end and a second end; the first end covers the flash 12.

[0089] like Figure 8 As shown, in the second direction Y, one side of the strip support 20 is a hollow groove 21, and the other side of the strip support 20 is a slide 22; the first direction X is the length extension direction of the strip support 20, and the first direction X is perpendicular to the second direction Y.

[0090] The convex lens 13 is located between the hollow groove 21 and the slide 22. A paddle 23 is installed on the convex lens 13 and inserted into the hollow groove 21. The convex lens 13 moves along the first direction X.

[0091] Specifically, in this embodiment of the invention, the strip bracket 20 includes, but is not limited to, being mounted on the first surface 11 of the mobile phone by bonding or snapping. After the convex lens 13 is mounted on the strip bracket 20, the lever 23 above the convex lens 13 is inserted into the hollow groove 21. By manually moving the lever 23, the convex lens 13 can be slid back and forth along the slide rail 22. Figure 7 As shown in (a), this is a schematic diagram of the phone without the flash focusing accessory installed; as Figure 7 As shown in (b), when the flash 12 is used as the light source for photography, the convex lens 13 is moved to an idle position away from the flash 12. The orthographic projection of the convex lens 13 does not overlap with the flash 12. At this time, the convex lens 13 is away from the front of the flash 12, and the light emitted by the flash 12 is scattered, which does not affect the photographic effect; Figure 7As shown in (c), when the flash 12 is used as the light source of the flashlight, the convex lens 13 is moved to the front of the flash 12. The light focusing characteristics of the convex lens 13 are used to convert the light emitted by the flash 12 into a concentrated beam, which is in the shape of a light column, increasing the brightness and illumination distance, thereby improving the lighting effect of the flash 12 when it is used as a flashlight.

[0092] In an optional embodiment of the present invention, reference is made to... Figure 9 , Figure 9 This is a schematic diagram of a sliding pad at different positions according to an embodiment of the present invention. (Refer to...) Figure 10 , Figure 10 This is a schematic diagram illustrating the different heights of an adjustable screw according to an embodiment of the present invention. The mobile phone flash focusing accessory provided in this embodiment also includes: a fixing component 25 and a height adjustment component.

[0093] based on Figure 7 and Figure 8 In the case of the mobile phone flash focusing accessory shown, the fixing component 25 is used to fix the second end to the first surface 11.

[0094] The height adjustment component is located between the strip bracket 20 and the first surface 11, and the height adjustment component is used to adjust the distance between the first end and the first surface 11.

[0095] Specifically, in the embodiments of the present invention, such as Figure 9 As shown, the height adjustment component includes a sliding pad 24, the height of which is d1, and the distance between the second end and the first surface 11 is d2; wherein d1 > d2; the sliding pad 24 slides left and right in the first direction X.

[0096] like Figure 9 As shown in (a1) and (a2), the sliding pad 24 is slid to a position close to the flash lamp 12, at which point the distance between the convex lens 13 and the flash lamp 12 is relatively close; as Figure 9 As shown in (b1) and (b2), the sliding pad 24 is slid to a position away from the flash lamp 12. At this time, the strip support 20 will be further raised. With the second end fixed, the distance between the convex lens 13 and the flash lamp 12 will increase, thereby adjusting the distance between the convex lens 13 and the flash lamp 12. This can adjust the focused size of the light column after focusing, that is, adjust the aperture size of the light column after focusing.

[0097] Or, such as Figure 10 As shown, the height adjustment assembly includes a rotating turntable 26 and a height-adjustable screw 27.

[0098] The upgradeable screw 27 is located on the side of the rotating disk 26 opposite to the first surface 11, and the rotating disk 26 is used to adjust the height of the upgradeable screw 27.

[0099] The height of the adjustable screw 27 can be adjusted by controlling the rotating turntable 26; for example... Figure 10 As shown in (b), when the adjustable screw 27 is lowered to its lowest position, the distance between the convex lens 13 and the flash lamp 12 is minimized; Figure 10 As shown in (c), by rotating the rotating turntable 26, the adjustable screw 27 can be raised, and the strip bracket 20 will be further raised. With the second end fixed, the distance between the convex lens 13 and the flash lamp 12 is increased, thereby realizing the adjustment of the distance between the convex lens 13 and the flash lamp 12. The focusing size of the focused light column can be adjusted, that is, the aperture size of the focused light column can be adjusted.

[0100] It should be noted that, Figure 9 and Figure 10 The specific structure of the strip support 20 is not shown in the diagram; it is only used as a simple illustration. Please refer to [link / reference needed] for the detailed structure of the strip support 20. Figure 8 .

[0101] In an optional embodiment of the present invention, reference is made to... Figure 11 , Figure 11 This is a schematic diagram of the structure of another mobile phone flash focusing accessory provided in an embodiment of the present invention on a mobile phone. The mobile phone flash focusing accessory provided in this embodiment of the present invention further includes: a card 29 and a card slot 28 located on one side of the flash 12; in a third direction E, the card slot 28 includes a third end and a fourth end, the third end being adjacent to the flash 12, and the third direction E being the length extension direction of the card slot 28.

[0102] The card 29 is inserted into the card slot 28, the convex lens 13 is fixed to one end of the card 29 adjacent to the flash lamp 12, and the card 29 moves along the third direction E.

[0103] Specifically, in this embodiment of the invention, the card slot 28 includes, but is not limited to, being mounted on the first surface 11 of the mobile phone by adhesive or snap-fit. After the convex lens 13 and the card 29 are mounted on the card slot 28, the convex lens 13 can be moved back and forth along the third direction E by pushing the card 29 by hand. Figure 11 As shown in (a), this is a schematic diagram without the card 29 and the convex lens 13 installed; Figure 11As shown in (b), when the flash 12 is used as the light source for photography, pushing the card 29 moves the convex lens 13 away from the position of the flash 12. The orthographic projection of the convex lens 13 does not overlap with the flash 12. At this time, the convex lens 13 moves away from the front of the flash 12, and the light emitted by the flash 12 is scattered, which does not affect the photographic effect; Figure 11 As shown in (c), when the flash lamp 12 is used as the light source of the flashlight, the card 29 is pushed to move the convex lens 13 in front of the flash lamp 12. The light focusing characteristics of the convex lens 13 are used to convert the light emitted by the flash lamp 12 into a concentrated beam, which is in the shape of a light column, increasing the brightness and illumination distance, so as to improve the lighting effect of the flash lamp 12 when it is used as a flashlight.

[0104] Similarly, since the plane where the card 29 is located is almost parallel to the plane where the card slot 28 is located, the same design as the height adjustment of the strip bracket 20 can be implemented for the card slot 28. That is, the mobile phone flash focusing accessory also includes: fixing component 25 and height adjustment component.

[0105] The fixing component 25 is used to fix the fourth end to the first surface 11.

[0106] The height adjustment component is located between the slot 28 and the first surface 11, and the height adjustment component is used to adjust the distance between the third end and the first surface 11.

[0107] The height adjustment component includes a sliding shim 24 with a height of d1 and a distance of d3 between the fourth end and the first surface 11; where d1 > d3; the sliding shim 24 slides left and right in the third direction E to adjust the distance between the third end of the slot 28 and the first surface 11, thereby adjusting the distance between the convex lens 13 and the flash lamp 12, and adjusting the focused size of the light column after focusing, that is, adjusting the aperture size of the light column after focusing.

[0108] Alternatively, the height adjustment assembly may include a rotating turntable 26 and a height-adjustable screw 27.

[0109] The upgradeable screw 27 is located on the side of the rotating disk 26 opposite to the first surface 11, and the rotating disk 26 is used to adjust the height of the upgradeable screw 27.

[0110] The height of the adjustable screw 27 can be adjusted by rotating the rotating turntable 26, thereby adjusting the distance between the third end of the slot 28 and the first surface 11, and thus adjusting the distance between the convex lens 13 and the flash lamp 12. This can adjust the focused size of the light column after focusing, that is, adjust the aperture size of the light column after focusing.

[0111] It should be noted that since the height adjustment design of the card slot 28 structure is the same as that of the strip bracket 20 structure, the specific implementation principle can be found in the description above, and will not be repeated here.

[0112] In an optional embodiment of the present invention, at least one of the convex lenses 13 is a prism to split the light emitted from the flash lamp 12 into various colors of light to achieve diversified display and improve the atmosphere effect in the lighting scene.

[0113] In an optional embodiment of the present invention, when the flash 12 is used as a light source for photography, a light-shielding film is provided between the convex lens 13 and the first surface 11. In other words, when the convex lens 13 is not in front of the flash 12, the light-shielding film must be provided at any idle position where the convex lens 13 is located to prevent the convex lens 13 from focusing light in the opposite direction when it is in an idle position, thus preventing sunlight or other external light sources from being focused onto the mobile phone or mobile phone case and causing overheating.

[0114] In an optional embodiment of the present invention, the convex lens 13 includes a plurality of sub-lenses; the optical axes of the plurality of sub-lenses converge at the same location.

[0115] Specifically, in the embodiments of the present invention, reference is made to Figure 12 , Figure 12 This is a schematic diagram of the structure of a convex lens provided in an embodiment of the present invention, as shown below. Figure 12 As shown, a convex lens 13 consists of three interconnected sub-lenses, whose optical axes are slightly tilted and converge at the same location. It should be noted that... Figure 12 (a) represents the top view. Figure 12 (b) represents a sectional view.

[0116] refer to Figure 13 , Figure 13 This is a schematic diagram of another convex lens provided in an embodiment of the present invention, as shown below. Figure 13 As shown, a convex lens consists of nine interconnected sub-lenses, whose optical axes are slightly tilted and converge at the same location. It should be noted that... Figure 13 (a) represents the top view. Figure 13 (b) represents a side sectional view. Figure 13 (c) represents the front sectional view.

[0117] refer to Figure 14 , Figure 14 This is a schematic diagram illustrating the structure of another convex lens provided in an embodiment of the present invention, as shown below. Figure 14 As shown, the convex lens consists of a small convex lens at the center, and convex lens bands 1 and 2 surrounding this small convex lens. The optical axes of the small convex lens, convex lens band 1, and convex lens band 2 converge at the same location. It should be noted that... Figure 14 (a) represents the top view. Figure 14 (b) represents a side sectional view.

[0118] It should be noted that convex lens strip 1 and convex lens strip 2 are composed of multiple convex lenses connected together in a ring.

[0119] refer to Figure 15 , Figure 15 This is a schematic diagram illustrating the principle analysis of a convex lens design provided by an embodiment of the present invention. Using this design, a large convex lens can be divided into multiple smaller lenses or lens strips, thus reducing the lens thickness. Specifically, as shown... Figure 15 As shown in (a) and (b), the greater the curvature of a convex lens (r2 > r1), the better the light-gathering effect, but the corresponding thickness is also greater (H2 > H1), making the convex lens too thick, which is inconvenient for installation, carrying, and aesthetics. Dividing a convex lens of the same area into multiple smaller convex lenses of the same thickness can increase the curvature, improve the light-gathering effect, and reduce the thickness of the convex lens. For example... Figure 15 As shown in (c), under this design, the height H1 of a low-curvature lens can achieve the refractive effect of a high-curvature lens, where H1 / r3 = H2 / r2.
