Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessories, specifically to a two-way fill light device for mobile phones. Background Technology

[0002] Currently, mobile phones have become an important tool for people to record their lives, taking photos and sharing moments anytime, anywhere. However, existing mobile phones have significant shortcomings in nighttime photography, as the lighting provided by the phone's camera itself is insufficient to meet shooting needs due to poor nighttime lighting conditions.

[0003] To capture more light, mobile phones need to extend the shutter speed, which makes the image blurry even with slight shaking when shooting handheld. In addition, although mobile phones have a night mode, the photographer often ends the shooting prematurely, causing the phone to only receive the first few frames of the short exposure time, resulting in a darker final image.

[0004] The current mobile phone's low-light photography performance is poor and urgently needs improvement to meet users' needs for high-quality shooting in nighttime scenarios. Summary of the Invention

[0005] The purpose of this invention is to provide a two-way supplementary lighting device for mobile phones to address the poor nighttime photography performance.

[0006] The objective of this utility model can be achieved through the following technical measures:

[0007] This utility model provides a bidirectional fill light device for mobile phones, including a front aperture assembly and a rear aperture assembly. The front and rear aperture assemblies are arranged parallel to each other and elastically connected. By pressing the rear aperture assembly, the distance between the unconnected ends of the front and rear aperture assemblies can be increased to clamp the device near the camera at the end of the mobile phone. When clamped, the front aperture assembly faces the front camera of the mobile phone, and the rear aperture assembly faces the rear camera of the mobile phone. The rear aperture assembly includes a first annular aperture portion and a second arc-shaped aperture portion formed by two symmetrical points on the outer circumference of the first aperture portion extending outward in an arc and connecting with each other.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] To make the description of this disclosure more detailed and complete, illustrative descriptions of the embodiments and specific examples of this utility model are provided below; however, this is not the only form of implementing or using the specific embodiments of this utility model. The embodiments cover the features of multiple specific embodiments and the methods, steps, and sequences for constructing and operating these specific embodiments. However, other specific embodiments may also be used to achieve the same or equivalent functions and sequence of steps.

[0020] Please refer to Figures 1 to 4 The present invention provides a bidirectional fill light device for mobile phones, comprising a rear aperture assembly 1 and a front aperture assembly 2. The rear aperture assembly 1 and the front aperture assembly 2 are arranged parallel to each other vertically and are elastically connected. Through this elastic connection, when the rear aperture assembly 1 is pressed, the distance between the unconnected ends of the front aperture assembly 2 and the rear aperture assembly 1 is increased, allowing it to be clamped onto the end of the phone near the camera. Typically, mobile phones have a front-facing camera and a rear-facing camera, located at the top of the phone. The camera located on the side of the phone screen is the front-facing camera, and the camera on the back of the phone is the rear-facing camera. When the bidirectional fill light device is clamped onto the top of the phone near the camera, the front aperture assembly 2 faces the front-facing camera, and the rear aperture assembly 1 faces the rear-facing camera.

[0021] The rear aperture assembly 1 includes a first aperture portion 11 and a second aperture portion 12, both ring-shaped. The second aperture portion 12 is formed by two symmetrical points on the outer periphery of the first aperture portion 11 extending outward in an arc and connecting with each other. Both the first aperture portion 11 and the second aperture portion 12 are luminous. Since the rear aperture assembly 1 faces the rear camera of the mobile phone, when the rear camera takes pictures at night in poor lighting conditions, the first aperture portion 11 and the second aperture portion 12 emit light to provide supplementary illumination. In an optional embodiment, one of the first aperture portion 11 and the second aperture portion 12 provides long-term illumination, i.e., continuous and uninterrupted illumination, while the other provides exposure illumination, i.e., it emits light only when the rear camera is exposed.

[0022] The front aperture assembly 2 includes a third aperture section 21 consisting of an "L"-shaped segment and an arc-shaped segment at its top. The third aperture section 21 is luminous. Since the front aperture assembly 1 faces the front camera of the mobile phone, when the front camera takes a picture at night in poor lighting conditions, the third aperture section 21 emits light to provide supplementary lighting.

[0023] The bidirectional fill light device for mobile phones provided in this embodiment, when clamped on the phone near the camera, ensures that the front and rear aperture components do not obstruct the front and rear cameras. When the front or rear camera takes photos in low-light conditions at night, the front and rear aperture components provide fill light for the front and rear cameras respectively, improving the phone's photo-taking performance in low-light environments.

[0024] The first aperture portion 11 and the second aperture portion 12 of the rear aperture assembly 1 are integrally connected, including an upper rear aperture cover 101 and a lower rear aperture cover 102 opposite to each other, and a rear aperture strip 103, which emits light when powered. The upper rear aperture cover 101 and the lower rear aperture cover 102 can be fixedly connected by means of snaps, adhesives, etc., and the two form a receiving cavity inside to accommodate the rear aperture strip 103. The rear aperture strip 103 includes a first aperture strip 1031 and a second aperture strip 1032. The first aperture strip 1031 fits the shape of the first aperture portion 11, and the second aperture strip 1032 fits the shape of the second aperture portion 12. In an optional embodiment, the first aperture strip 1031 provides exposure illumination for the rear camera of the mobile phone, and the second aperture strip 1032 provides long-term illumination for the rear camera of the mobile phone.

[0025] The front aperture assembly 2 also includes an electrical component 22 connected to the third aperture section 21. For example, the third aperture section 21 and the electrical component 22 are assembled from a single injection-molded upper shell and two separate lower shells cut according to the shape of the third aperture section 21 to form a housing. Internally, the third aperture section 21 houses a front aperture strip 211 that conforms to its shape, providing long-term illumination for the phone's front-facing camera. The electrical component 22 houses a control circuit board 221. The first aperture strip 1031, the second aperture strip 1032, and the front aperture strip 211 are electrically connected to the control circuit board 221. Under the control of the control circuit board 221, the illumination of the first aperture strip 1031 and the second aperture strip 1032 during rear camera photography and the illumination of the front aperture strip 211 during front camera photography can be controlled respectively. The control circuit board 211 receives operation commands from the control terminal and performs the above operations. In one optional embodiment, the control terminal can obtain the delayed exposure time when the rear camera of the mobile phone takes a picture, thereby controlling the first aperture band 1031 to emit light at the same time as the rear camera of the mobile phone takes a picture. The electrical unit 22 also contains a power supply device (not shown in the figure) controlled by the control circuit board 221 for supplying power to the first aperture band 1031, the second aperture band 1032 and the front aperture band 211 respectively.

[0026] The rear aperture assembly 1 and the front aperture assembly 2 are elastically connected. For example, the rear aperture assembly 1 has two symmetrical snap fasteners 104. Each snap fastener 104 includes a horizontal plate and two connecting lugs protruding from the surface of the plate, each connecting lug having a through hole. Corresponding to each snap fastener 104, the front aperture assembly 2 has two mating lugs 23 with through holes. The two connecting lugs are respectively positioned on the outside of the two mating lugs 23. An elastic element passes through the through holes of the connecting lugs and the mating lugs 23, elastically connecting the front aperture assembly 2 and the rear aperture assembly 1. The elastic element can be a spring. Pressing the rear aperture assembly 1, under the cooperation and action of the snap fasteners 104, the mating lugs 23, and the elastic element, increases the distance between the unconnected ends of the front aperture assembly 2 and the rear aperture assembly 1, allowing it to be clamped onto the mobile phone.

[0027] The front aperture assembly 2 has a soft pad 24 on the surface of the section that holds the phone. Since the front aperture assembly 2 is in contact with the screen on the front of the phone when it is held, the pad 24 helps to prevent damage to the phone screen.

[0028] This invention provides supplementary lighting for the front and rear cameras of a mobile phone by clamping the front and rear aperture components near the camera position at the end of the phone, thereby improving the phone's photo-taking effect in low-light environments at night.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
