Description

Technical Field

[0001] This utility model relates to the field of supplementary lighting equipment, and in particular to a supplementary lighting equipment for underwater photography. Background Technology

[0002] With the increasing popularity of diving, the demand for underwater photography is also constantly growing. Traditional underwater photography typically uses underwater cameras and waterproof housings. To obtain better photo results, additional lighting equipment is also required, which results in a large overall size and poor portability and operability.

[0003] Nowadays, diving enthusiasts prefer to use their phones directly for underwater photography because phones are portable, allow for quick sharing, eliminate the need to purchase a separate camera, and reduce equipment costs. However, most products on the market currently use phone cases with external lights for underwater photography, but these devices suffer from limited battery life. To enhance the lighting effect, the light's wattage needs to be as high as possible, but this raises heat dissipation issues.

[0004] Furthermore, the unique underwater environment makes controlling the lighting and camera operation challenging. Existing products typically use push-button spring switches to control the lights and camera, but in deep-sea diving areas exceeding 10 meters, the high water pressure can cause these switches to malfunction and fail to spring back. Therefore, to achieve a better underwater photography experience, there is a need to design an underwater lighting device that integrates advantages such as long-range illumination, good heat dissipation, long battery life, and small size, requiring improvements to existing technologies. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide an underwater shooting supplementary lighting device, which has the characteristics of compact structure and comprehensive functions.

[0018] Preferably, a second groove is provided on the outer wall of the first housing, and a rotating shaft is provided in the second groove, with the lever placed in the second groove.

[0019] Preferably, it also includes a main circuit board, wherein the power supply, the first Hall sensor and the supplementary lighting component are electrically connected to the main circuit board, and the main circuit board is installed in the receiving cavity, and the first Hall sensor is installed on the main circuit board.

[0021] The Hall effect Bluetooth component includes a first circuit board, a Bluetooth module, a trigger component, and several second Hall sensors, wherein the Bluetooth module and several second Hall sensors are all fixedly mounted on the first circuit board.

[0022] The first circuit board is fixedly installed in the receiving cavity. The side of the first housing is provided with a third groove and a switch cover. The switch cover covers the third groove and is provided with a water guiding hole. The trigger component is connected to the switch cover.

[0023] Preferably, the triggering component includes several buttons and several springs. Each button is mounted on the switch cover, with one end protruding from the surface of the switch cover and a third magnet fixedly mounted on its other end. One end of the spring abuts against the button, and the other end abuts against the bottom wall of the third groove. Preferably, the supplementary lighting component includes a lampshade and a lamp plate. The lampshade is disposed above the lamp plate, and several LEDs are arranged on the lamp plate.

Preferably, a horizontal plate is provided at the upper part of the receiving cavity, and the horizontal plate is placed below the partition for fixing the power supply and supporting the partition.

[0027] Preferably, a support ring is installed between the partition and the first transparent plate, with one end face of the support ring abutting against the first transparent plate and the other end face abutting against the partition.

[0028] Preferably, the partition is made of metal to facilitate heat dissipation of the shooting equipment.

[0029] Preferably, the heat sink is an aluminum plate.

[0030] Compared with the prior art, this utility model has the following advantages:

[0031] (1) In order to increase the shooting and lighting time, the device is equipped with a power supply, which is located in the housing cavity of the first housing, so that the device has good integration; further, in order to avoid the problem of excessive temperature of the lighting component during long-term lighting, the present application provides a heat sink, which is placed below the lamp plate of the lighting component and covers the surface of the first housing and extends to the area where the outer surface of the housing cavity is located. Therefore, the heat of the lamp plate can be carried away, and the power supply can also be cooled; in order to improve the heat dissipation effect, the heat sink is made of aluminum plate.

[0032] (2) This technical solution uses a Hall effect switch assembly to control the opening and closing of the supplementary lighting assembly. Based on the principle of the Hall effect switch, a lever is used to control the relative position of the second magnet and the first Hall sensor to trigger a control signal, replacing the traditional push-button elastic switch. Specifically, when the second magnet is close to the Hall sensor, the Hall effect switch assembly is in an on or off state, transmitting a signal to the main circuit board. The main circuit board then sends a control signal to the supplementary lighting assembly, triggering the lighting assembly to light up. When the second magnet is far from the Hall sensor, the Hall effect switch assembly is in an off or closed state, triggering the lighting assembly to turn off. This ensures that the switch can stably control the supplementary lighting equipment during diving, is not prone to failure, and this type of switch design is not affected by diving depth or water pressure.

[0033] (3) This technical solution uses a Hall effect Bluetooth component to control a shooting device (such as a mobile phone). The Hall effect Bluetooth component includes a first circuit board, a Bluetooth module, a trigger component, and several second Hall effect sensors. The trigger component includes several buttons and several springs. A third groove is provided on the side of the first housing. A switch cover covers the third groove and has a water-guiding hole. The trigger component is connected to the switch cover. During diving, water can enter the third groove through the water-guiding hole, balancing the pressure between the third groove and the outside. This prevents the trigger component from failing to bounce after being subjected to water pressure, avoiding the problem that traditional switches cannot work in deep water areas, thus preventing normal shooting. Based on the principle of Hall effect switches, the Hall effect Bluetooth component of this application can more stably achieve Bluetooth connection with shooting devices (such as mobile phones).

[0034] (4) The present technical solution is provided with a partition, and a clamping assembly is provided on the partition for clamping the shooting device; the clamping assembly includes multiple clamping blocks, each clamping block is movably mounted on the partition, each clamping block has a first magnet block at the bottom and a lug at the top, so that the device can adapt to shooting devices of different sizes, enhance the application range of the device, and better fix the shooting device to prevent it from moving or falling off the partition.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. 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.

[0068] A preferred embodiment of this application provides an underwater photography lighting device, such as... Figures 1-4 , Figure 13 and Figure 14 As shown, the underwater lighting equipment includes: a first housing 1, which has an opening 11 and a receiving cavity 12 in a region away from the opening 11, wherein a first transparent plate 13 is installed at the opening 11, and the first transparent plate 13 is preferably made of glass; a second housing 2, which is fixedly connected to the first housing 1, wherein a second transparent plate 21 is installed on the second housing 2, and the space between the second housing 2 and the first housing 1 can be used to install the shooting equipment. Further, as... Figure 6As shown, the second housing 2 includes a first frame 22 and a second frame 23, with a second transparent plate 21 fixedly installed between the first frame 22 and the second frame 23; a supplementary lighting component 3, disposed at the edge of the opening, preferably arranged around the opening 11, specifically in a ring or rectangle; a power supply 4, installed within the receiving cavity 12; and a heat dissipation plate 5, installed on the surface of the first housing 1, positioned below the supplementary lighting component 3, and extending towards the area of ​​the outer surface of the receiving cavity 12. Preferably, it also includes a partition 6, fixedly installed within the first housing 1, and the partition 6 is provided with a clamping component 61 for clamping the shooting device. To ensure sealing, a sealing ring 10 is provided between the second housing 2 and the first housing 1, and the second housing 2 and the first housing 1 are also fixed together by a rotating buckle.

[0069] Specifically, such as Figures 6-7 As shown, the clamping assembly 61 includes multiple clamping blocks 611, each of which is movably mounted on the partition 6. This allows the device to adapt to shooting devices of different sizes, enhancing its applicability to different models of shooting devices. Furthermore, the partition 6 is made of metal, and each clamping block 611 has a first magnet block 612 at its bottom and a lug 613 at its top. The lug 613 serves to better secure the shooting device and prevent it from moving or detaching from the partition 6.

[0070] Specifically, such as Figure 3 As shown, a first groove 14 is provided on the surface of the first housing 1, and the heat sink 5 is placed in the first groove 14. This ensures that after the heat sink 5 is installed, the outer surface of the heat sink 5 is flush with the outer surface of the first housing 1, thus ensuring good heat dissipation performance while also taking into account aesthetics.

[0071] Specifically, such as Figure 5 , Figure 13 and Figure 14 As shown, it also includes a Hall switch assembly 7, which is installed on the side of the first housing 1 and is used to control the opening or closing of the supplementary lighting assembly 3; the Hall switch assembly 7 includes a first Hall sensor 71, a lever 72 and a second magnet 73, the second magnet 73 is installed at the end of the lever 72, the lever 72 is rotatably installed on the outer wall of the first housing 1, and the first Hall sensor 71 is installed in the receiving cavity 12.

[0072] Specifically, a second groove 15 is provided on the outer wall of the first housing 1, and a rotating shaft 151 is provided in the second groove 15. The lever 72 is placed in the second groove 15. By providing the second groove 15, accidental activation of the lever 72 can be effectively prevented, and damage to the Hall switch assembly 7 can be avoided. Specifically, a torsion spring 74 is also provided between the lever 72 and the rotating shaft 151, so that the lever 72 can be released after rotating a certain angle and return to its original position.

[0073] Specifically, such as Figure 13 As shown, it also includes a main circuit board 8. The power supply 4, the first Hall sensor 71 and the supplementary lighting component 3 are electrically connected to the main circuit board 8, and the main circuit board 8 is installed in the receiving cavity 12. The first Hall sensor 71 is installed on the main circuit board 8.

[0074] This technical solution uses a Hall effect switch assembly 7 to control the on / off state of the supplementary lighting assembly 3. Based on the basic principle of Hall effect switches, a lever 72 controls the relative position of the second magnet 73 and the first Hall sensor 71 to trigger a control signal, replacing the traditional push-button type elastic switch. Specifically, when the second magnet 73 is close to the first Hall sensor 71, the Hall effect switch assembly 7 is in the ON state, transmitting a signal to the main circuit board 8. The main circuit board 8 then sends a control signal to the supplementary lighting assembly 3, triggering it to light up. When the second magnet 73 is away from the first Hall sensor 71, the Hall effect switch assembly 7 is in the OFF state, triggering it to turn off. This design ensures stable control of the supplementary lighting equipment during diving, reducing the likelihood of failure. Furthermore, this type of switch design is unaffected by diving depth or water pressure.

[0075] It should be noted that the first Hall sensor 71 is directly obtained from the prior art, and its specific structure will not be described in this application. For ease of understanding, this application further describes the principle of the switch-type Hall sensor as follows:

[0076] When the user presses the lever 72, the second magnet 73 approaches the first Hall sensor 71. The first Hall sensor 71 senses the magnetic field and outputs a changing voltage level (high or low). The controller chip (MCU) receives this changing voltage level and outputs a PWM signal to the field-effect transistor controlling the supplementary lighting component 3, thus putting the supplementary lighting component 3 into operation. Since a torsion spring 74 is also provided between the lever 72 and the rotating shaft 151, when the user releases the lever, the second magnet 73 moves away from the first Hall sensor 71. At this time, the first Hall sensor 71 does not sense the magnetic field and has no voltage output to the MCU, thus maintaining its current operating state. This constitutes one triggering process.

[0077] It should be noted that the brightness of the supplementary lighting component 3 can be set to three levels. For example, when the lever 72 is turned for the first time, the light of the supplementary lighting component 3 is at level one. When the lever 72 is turned for the second time, the light of the supplementary lighting component 3 is at level two. When the lever 72 is turned for the third time, the light of the supplementary lighting component 3 is at level three. When the lever 72 is turned for the fourth time, the light of the supplementary lighting component 3 is turned off, and so on.

[0078] like Figures 8-11 As shown, it also includes a Hall effect Bluetooth component 9 for controlling the shooting equipment.

[0079] Specifically, the Hall effect Bluetooth component 9 includes a first circuit board 91, a Bluetooth module 92, a trigger component 93, and several second Hall sensors 94. The Bluetooth module 92 and the several second Hall sensors 94 are all fixedly mounted on the first circuit board 91. It should be noted that the Bluetooth module 92 is directly obtained from existing technology and can connect to the shooting device (mobile phone). The connection method between Bluetooth and the mobile phone is a common existing technology, and its implementation will not be described in detail in this application. The first circuit board 91 is electrically connected to the power supply 4 of this application, meaning that the first circuit board 91 draws power from the power supply 4, eliminating the need for an additional button battery and avoiding the frequent battery replacement problems associated with traditional push-button Bluetooth switches. Furthermore, the power supply 4 of this application can also function as a power bank, directly providing power to the shooting device (mobile phone).

[0080] The first circuit board 91 is fixedly installed in the receiving cavity 12. The side of the first housing 1 is provided with a third groove 16 and a switch cover 17, and the switch cover 17 covers the third groove 16. Specifically, the switch cover 17 is fixedly connected to the first housing 1, which can be connected by snap-fit ​​or bolt.

[0081] Furthermore, a water guide hole 171 is provided on the switch cover 17, and the trigger component 93 is connected to the switch cover 17. During diving, water can enter the third groove 16 through the water guide hole 171, so that the pressure of the third groove 16 is balanced with the external pressure. In this way, the trigger component 93 will not fail to rebound after being subjected to water pressure, avoiding the problem that traditional switches cannot work in deep water environments and causing shooting to be unable to proceed normally.

[0082] Specifically, such as Figure 12As shown, the trigger assembly 93 includes several button pieces 931 and several springs 932. Each button piece 931 is mounted on the switch cover 17, with one end protruding from the surface of the switch cover 17 and the other end fixedly mounted with a third magnet block 95. One end of the spring 932 abuts against the button piece 931, and the other end abuts against the bottom wall of the third groove 16. When the button piece 931 is pressed, it can slide relative to the switch cover 17 in a first direction. After the pressure is released, it can slide relative to the switch cover 17 in the opposite direction under the force of the spring 932. The first direction can be downward or upward, or left or right, or forward or backward, depending on the mounting position of the trigger assembly 93 on the first housing 1. Furthermore, the switch cover 17 is provided with a button hole for the end of the button piece 931 to pass through.

[0083] In practical applications, four of the aforementioned button 931, spring 932, and third magnet 95 are provided, each capable of performing different functions. Specific examples are as follows:

[0084] (1) The function of the first button 931 is set as follows: short press to magnify focal length, long press to magnify focal length steplessly;

[0085] (2) The function of the second button 931 is set as follows: short press to reduce focal length, long press to reduce focal length steplessly;

[0086] (3) The function of the third button 931 is set as follows: short press to take a picture, long press to pair via Bluetooth;

[0087] (4) The function of the fourth button 931 is set to switch between taking photos and recording videos by short press.

[0088] Furthermore, the basic working principle of the Hall effect Bluetooth component 9 as a shooting switch is as follows:

[0089] The user pre-pairs the Hall effect Bluetooth component 9 with the mobile phone via Bluetooth. For example, by pressing and holding the third button 931, when the third magnet 95 is close to the second Hall sensor 94, the second Hall sensor 94 will sense the magnetic field and output a changing level (high or low). The Bluetooth module 92 will receive the changing level and send a pairing signal to the mobile phone. After pairing is complete, when the user needs to take a picture while underwater, press one of the buttons 931, such as by briefly pressing the third button 931. When the third magnet 95 at the end of the third button 931 is close to the second Hall sensor 94, the second Hall sensor 94 will sense the magnetic field and output a changing level (high or low). The Bluetooth module 92 will receive the changing level and send a control command to the mobile phone to realize the shooting operation.

[0090] Specifically, such as Figure 3As shown, the supplementary lighting component 3 includes a lampshade 31 and a lamp plate 32. The lampshade 31 is disposed above the lamp plate 32, and a plurality of LEDs are arranged on the lamp plate 32. The lamp plate 32 is mounted on a heat sink 5. The lampshade 31 of this device is fixedly connected to the lamp plate 32 by adhesive to ensure good sealing; and the light emitted by the lamp plate 32 is evenly distributed after being emitted through the lampshade 31, which can improve the brightness and clarity of the captured image.

[0091] Specifically, the lampshade 31 employs a lens structure to focus light. The lampshade 31 of this application uses a lens-focusing design to further concentrate the light intensity of the LED beads, achieving a longer illumination distance during diving.

[0092] The lampshade 31 adopts a lens structure, which can be implemented as follows:

[0093] The lampshade 31 is made of a plastic optical lens material, such as PC plastic, which can be directly obtained from existing technology and formed into the lampshade of this application through injection molding. Preferably, it is a ring-shaped lampshade (i.e., a ring lens). Specifically, as shown... Figure 16 As shown, the lampshade includes a first light surface 311 and a second light surface 312. The curvature of the first light surface 311 is greater than that of the second light surface 312. When the lamp beads on the lamp board are lit, the light emitted by them (e.g., light with a light emission angle of 120°) is collected and shaped by the first light surface of the ring lampshade, and then passes through the second light surface, which can reduce the light emission angle (e.g., convert the light emission angle of 120° to 90°), making the light more concentrated to achieve a light-focusing effect, thereby enhancing the illumination brightness.

[0094] Specifically, the power of the supplementary lighting component 3 is at least 20W, which is high power compared to existing underwater supplementary lights. Based on this, this application adopts a high-power supplementary lighting component 3, which can illuminate a longer distance. The first housing 1 of this application adopts an independent power supply cavity 12 structure design, which can provide a larger installation space for the power supply 4, that is, to place a larger capacity battery, so as to ensure that this device can achieve a longer shooting time and has the ability to provide supplementary lighting over a longer distance and for a longer duration.

[0095] Specifically, such as Figures 1-4 As shown, a light-blocking plate 18 is also provided on the first housing 1, which is arranged around the opening 11 and located inside the lampshade 31; the height of the light-blocking plate 18 is greater than or equal to the height of the lampshade 31. This arrangement can prevent the light generated by the supplementary lighting component 3 from entering the shooting device and causing glare or stray light, thus effectively improving the shooting quality.

[0096] Specifically, such as Figure 8 As shown, a horizontal plate 19 is provided on the upper part of the receiving cavity 12, and the horizontal plate 19 is placed below the partition 6 for fixing the power supply 4 and supporting the partition 6.

[0097] Specifically, such as Figures 8-9 As shown, a support ring 62 is installed between the partition 6 and the first transparent plate 13. One end face of the support ring 62 abuts against the first transparent plate 13, and the other end face abuts against the partition 6; so that the first transparent plate 13 is installed more firmly and to prevent the first transparent plate 13 from being detached from the first shell 1 or damaged by external water pressure when diving.

[0098] Specifically, the partition 6 is made of metal to facilitate heat dissipation of the shooting equipment.

[0099] Specifically, the heat sink 5 is an aluminum plate or a thermally conductive polymer material. To achieve better heat dissipation, the heat sink 5 can cover the entire outer surface of the receiving cavity 12. Since the power supply 4 is installed inside the receiving cavity 12, the heat sink 5 can also dissipate heat from the power supply 4. Preferably, the heat sink 5 of this device can occupy 60%-90% of the area of ​​the first housing 1.

[0100] In order to fit more snugly to the outside of the first housing 1 and achieve better heat dissipation, the heat dissipation plate 5 is also provided with a bending part 51.

[0101] The device also includes a power display screen 100, which displays the battery level in real time during diving.
