[0002] With the rapid development of digital photography technology, camera modules have been widely used in various fields. Traditional camera modules typically integrate lighting components (such as fill lights) inside the camera or as fixed accessories, resulting in insufficient device flexibility. For example, in low-light environments, users need to carry external lighting equipment, increasing the complexity of use. Furthermore, when fixed, integrated lighting components are damaged or need upgrading, it often requires replacing the entire camera module, which is costly.

[0003] In existing technologies, some camera modules attempt to connect lighting equipment via external interfaces. However, these connections typically rely on wired connections or complex mechanical structures, which can lead to problems such as poor contact and misalignment. For example, some security cameras use threaded-connection fill lights, which are prone to wear and tear after frequent disassembly, affecting the stability of the electrical connection. Furthermore, traditional lighting components have limited functionality and cannot meet the needs of multispectral or variable-angle shooting.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Based on the existing technical problems pointed out in the background, such as Figure 1 As shown, in a preferred embodiment of the present invention, the camera module includes a camera body 130, a housing, and a lighting assembly 120. The camera body 130 is manufactured using high-precision molds and is made of aluminum alloy or engineering plastic to ensure lightweight and durability. First electrical contacts 131 are provided on the camera body 130; these contacts are typically made of gold-plated copper alloy to improve conductivity and corrosion resistance. The first electrical contacts 131 are arranged on the outer surface of the camera body 130 for transmitting power and signals, such as LED control signals or data feedback.

[0037] like Figure 2 As shown, a receiving cavity is formed inside the housing. This cavity is formed by injection molding and its dimensions precisely match the camera body 130 to provide stable support. The housing material can be selected from polycarbonate or metal composite materials, possessing sufficient strength to protect the internal components. The design of the receiving cavity allows the camera body 130 to be easily inserted and fixed, while leaving space for heat dissipation and wiring. The lighting assembly 120 is detachably connected to the housing, for example, by magnetic adsorption or mechanical clips. The lighting assembly 120 is provided with second electrical contacts 121, which automatically align and electrically connect with the first electrical contacts 131 upon connection. In practical applications, the camera module of this embodiment can be used in security monitoring systems. For example, in low-light environments, the user can quickly install the lighting assembly 120 onto the housing. After the second electrical contacts 121 contact the first electrical contacts 131, power is immediately supplied to the lighting assembly 120 to provide supplemental lighting. If supplemental lighting is not needed, the user can remove the lighting assembly 120 to reduce energy consumption. Extending this concept, this embodiment can also be applied to automotive dashcams, where the light assembly 120 serves as an auxiliary light source for nighttime use, and its detachable design allows for easy replacement of light modules with different brightness levels. The advantages are: the modular design improves the flexibility and maintainability of the device, and the electrical connections require no additional cables, reducing potential points of failure.

[0038] In another preferred embodiment, the camera body 130 includes a lens assembly 132 and an image sensing assembly 133. The lens assembly 132 is disposed within the housing and protrudes from the edge of the housing; this design allows the lens to capture a wider field of view. The lens assembly 132 consists of multiple optical glass lenses arranged by bonding or mechanical fixing to reduce aberrations and improve image quality. The portion protruding from the edge of the housing is typically covered with a protective lens to prevent dust and scratches. The image sensing assembly 133 is disposed in the light-sensing path of the lens assembly 132 and employs a CMOS or CCD sensor to receive light signals passing through the lens assembly 132 and convert them into electronic image signals.

[0039] like Figure 3-4 As shown, in one specific embodiment, the light assembly 120 and the housing are detachably connected via at least one of a magnetic structure, a snap-fit ​​structure, or a threaded structure. The magnetic structure uses neodymium iron boron magnets embedded in the mating surfaces of the housing and the light assembly 120 to form a strong magnetic attraction. For example, in consumer cameras, the light assembly 120 is magnetically connected, and it automatically attaches simply by the user bringing it close to the housing, facilitating quick and easy installation. The snap-fit ​​structure uses plastic or metal claws, with the claws on the light assembly 120 engaging with grooves on the housing to provide mechanical locking. The threaded structure is similar to a traditional lens mount, achieving connection through rotation, and is suitable for high-vibration environments.

[0040] In extended applications, this embodiment can be used in industrial inspection cameras, where the magnetic structure allows for quick replacement of the light assembly 120 in confined spaces, while the snap-fit ​​structure is used in security scenarios requiring high reliability. For example, in drone photography, the light assembly 120 is magnetically connected, making it less prone to detachment even during flight and vibrations. The advantages are: multiple connection methods provide flexibility, the magnetic structure facilitates quick operation, and the snap-fit ​​and threaded structures enhance stability, adapting to different application needs.

[0041] In one specific embodiment, the lighting assembly 120 is detachably connected to the housing via at least one of a magnetic structure, a snap-fit ​​structure, or a threaded structure. The magnetic structure uses neodymium iron boron magnets embedded in the mating surfaces of the housing and the lighting assembly 120 to form a strong magnetic attraction. For example, in consumer cameras, the lighting assembly 120 is magnetically connected, and it automatically attaches simply by the user bringing it close to the housing, facilitating quick and easy installation.

The threaded structure is similar to a traditional lens, achieving connection through rotation, and is suitable for high-vibration environments.

For example, in drone photography, the lighting assembly 120 is magnetically connected, preventing it from easily detaching even during flight due to vibration. The advantages are: multiple connection methods provide flexibility, the magnetic structure facilitates quick operation, and the snap-fit ​​and threaded structures enhance stability, adapting to different application requirements.

[0042] In another preferred embodiment, at least one of the first electrical contact 131 and the second electrical contact 121 is a resilient contact. The resilient contact is made of beryllium copper alloy, exhibiting high elasticity and conductivity. When the light assembly 120 is connected to the housing, the resilient contact is compressed, generating a reaction force to maintain a tight contact and prevent connection interruption due to vibration or temperature changes. For example, in an action camera, the first electrical contact 131 is fixed, and the second electrical contact 121 is a spring-loaded pin type, with the spring-loaded pin compressed by 0.5-1 mm during connection to ensure a low-resistance connection. Extending this embodiment, the resilient contact design is resistant to humidity and large temperature variations. For example, in an underwater camera, the contact employs a sealed resilient design to prevent water ingress and short circuits. The advantages are: the resilient contact improves connection reliability and durability, reduces maintenance requirements, and simplifies the assembly process.

[0043] In one specific embodiment, the lighting assembly 120 includes a ring light. The ring light 122, composed of multiple LEDs arranged in a ring, is mounted around the lens assembly 132 to provide uniform illumination. The diameter of the ring light can be adjusted according to the lens size; for example, in macro photography, a ring light diameter of 20-30 mm ensures no shadows on the object surface. The LEDs have adjustable color temperature, from warm to cool light, to adapt to different shooting scenarios. In this embodiment, the ring light provides soft light and reduces shadows. Extended applications include scientific microscopes, where the ring light surrounds the objective lens to provide uniform brightness to the sample. Advantages include: the ring design avoids central obstruction, improving image quality; and adjustable brightness expands the range of applications.

[0044] In another preferred embodiment, the camera module further includes a control circuit disposed within the housing and electrically connected to the first electrical contact 131 and the image sensing component 133, respectively, for controlling the activation and deactivation and brightness of the lighting component 120. The control circuit, integrated within the housing, employs a microcontroller (such as an ARM Cortex-M series) and a driver chip (such as a MOSFET). The control circuit automatically adjusts the light brightness by analyzing the image signal. For example, under low-light conditions, if the image sensing component 133 detects increased signal noise, the control circuit automatically activates the lighting component 120 and adjusts the brightness to the optimal level.

[0045] In another preferred embodiment, an image stabilization mechanism is disposed between the lens assembly 132 and the housing. The image stabilization mechanism includes a voice coil motor and a position sensor. The image stabilization mechanism is integrated between the lens assembly 132 and the housing. The voice coil motor drives the lens assembly 132 to move via electromagnetic force, compensating for hand shakiness or vibration. The position sensor (such as a Hall sensor) detects the lens position and feeds it back to the control circuit to achieve closed-loop control. For example, in handheld photography, the image stabilization mechanism can reduce blur by 2-3 stops of shutter speed.

[0046] In one specific embodiment, the lighting assembly 120 includes multiple light sources with different spectral characteristics, and the camera module also includes a spectral selection switch for switching between different combinations of light sources. The light sources include infrared LEDs, ultraviolet LEDs, and visible LEDs, and the spectral selection switch can be a physical button or an electronic switch. Users can select different combinations of light sources via the switch, for example, switching to infrared mode for night vision in security monitoring. Extended applications include agricultural monitoring, where multispectral light sources analyze plant health.

[0047] In another preferred embodiment, the camera module further includes a wireless communication module housed within the housing. This module communicates with external devices, receives control commands, and transmits image data. The wireless communication module employs a Wi-Fi or Bluetooth chip, integrated within the housing, for communication with smartphones or cloud servers. Users can control the lighting assembly 120 and receive image data via an app. Extended applications include IoT devices, enabling remote monitoring. Wireless connectivity simplifies wiring and improves device portability.

[0048] In one specific embodiment, a heat dissipation structure is provided on the housing, comprising heat dissipation fins and a thermally conductive material, for dissipating heat generated by the camera body 130 and the lighting assembly 120. The heat dissipation fins are made of aluminum alloy and are attached to the outside of the housing, and the thermally conductive material is silicone grease or graphite sheet, dissipating heat generated by the camera body 130 and the lighting assembly 120. For example, in high-resolution video recording, the heat dissipation structure prevents performance degradation due to overheating.

[0049] In another preferred embodiment, the lighting assembly 120 includes a reflector or lens with an adjustable illumination angle for changing the range of illumination and the application scenario. The reflector adjusts its angle via a stepper motor to change the range of illumination.

[0050] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
