Supplementary light lamp

Abstract

This application discloses a supplementary lighting lamp, comprising: a housing having an air duct extending through the top and bottom, and an electronic control module disposed within the housing; a lamp head detachably connected to the open end of the top of the housing, with a through hole in the middle of the lamp head connecting to the air duct; and a support frame movably connected to the outer wall of the housing, with an air outlet at the bottom of the support frame near the air duct, a cooling fan disposed at the air outlet, and an air inlet on the side of the support frame opposite to the air outlet. The air inlet, air outlet, air duct, and through hole form a through-ventilation channel, which, combined with the cooling fan, creates a directional airflow path.

Description

Technical Field

[0001] This application relates to the field of photographic equipment, and in particular to a fill light. Background Technology

[0002] With the rapid development of digital imaging technology, photography has moved from the professional field to everyday life. Whether it's creating social media content, live-streaming e-commerce, or simply recording daily life, high-quality lighting has become a core element in enhancing the quality of images, making fill lights an important component of photographic equipment.

[0003] In related technologies, the heat dissipation of fill lights relies on the direct blowing of a fan built into the housing. To improve the heat dissipation effect, some medium and high power fill lights will install a miniature axial fan inside the housing to accelerate the removal of heat by forced airflow.

[0004] However, the direct-blowing heat dissipation path of the fan is limited to a local area inside the casing, and cannot dissipate heat to other modules and components at the same time. In addition, the heat dissipation path is short and lacks a stable and comprehensive heat dissipation channel, which causes heat to circulate only inside the casing and is difficult to dissipate effectively.

[0032] This application proposes a supplementary light 100, please refer to... Figures 1 to 4 The fill light 100 includes:

[0033] The housing 110 has an air duct 111 that runs through the top and bottom ends, and an electronic control module is installed inside the housing 110.

[0034] The lamp holder 120 is detachably connected to the open end of the top of the housing 110, and the lamp holder 120 has a through hole 121 in the middle for connecting the ventilation channel 111.

[0035] The support frame 130 is movably connected to the outer wall of the housing 110. The bottom of the support frame 130 near the air duct 111 has an air outlet 131. A cooling fan 140 is installed at the air outlet 131. The side of the support frame 130 opposite to the air outlet 131 has an air inlet 132.

[0036] The main function of the housing 110 is to house various modules and components, such as electronic control modules and power supply modules. In this embodiment, the housing 110 can be made of a metal with excellent heat dissipation properties, such as aluminum alloy or magnesium alloy.

[0037] In this embodiment, the main function of the air duct 111 is to allow airflow to pass through the housing 110. There are various options for the implementation of the air duct 111. In a preferred embodiment, a hollow air duct 111 is formed through the top and bottom of the housing 110, and an annular inner cavity is formed inside the housing 110 to accommodate various modules and components.

[0038] In this embodiment, the shape of the air duct 111 can be chosen in several ways. For example, the air outlets at both ends of the air duct 111 can be polygons with more than four sides. In a preferred embodiment, please refer to... Figure 1 The air vent is octagonal.

[0039] The main function of the lamp head 120 is to provide illumination and supplementary lighting. In this embodiment, the material of the lamp head 120 can be chosen from various options. In a preferred embodiment, the lamp head 120 is made of transparent plastic. Transparent plastic is light-transmitting, allowing light to pass through to the external environment to achieve the functions of illumination and supplementary lighting. Furthermore, the material is lightweight, which is beneficial for the miniaturization design of the supplementary light 100 in this application, improving the user experience.

[0040] In this application embodiment, there are several options for the arrangement of the lamp holder 120. In a preferred embodiment, please refer to... Figure 2 The light fixture is detachably connected to the open section at the top of the housing 110. The lamp head 120 can be disassembled to accommodate different scenarios, expand its applicability, and enhance the product's practicality. Furthermore, the lamp head 120 can be detachably connected via plug-in, bolt, or magnetic connection, etc. The specific method can be determined according to actual needs, as long as the lamp head 120 can be detached; this utility model does not impose any limitations on this.

[0041] To improve heat dissipation efficiency and expand the functionality of the fill light 100, please refer to [link / reference needed]. Figure 1The lamp head 120 has a through hole 121 in the middle of the ventilation duct 111. The airflow generated by the cooling fan 140 enters the ventilation duct 111, flows along the ventilation duct 111 through the heating component, carries away the heat and discharges it through the through hole 121, thus achieving efficient heat dissipation. At the same time, the discharged airflow can directly act on the external environment, enabling the supplementary light 100 of this application to have the function of a blower.

[0042] In this application embodiment, the support frame 130 can be configured in several ways. In a preferred embodiment, please refer to... Figure 2 The support frame 130 is movably connected to the outer wall of the housing 110. Furthermore, there are multiple options for the movable connection between the support frame 130 and the housing 110, such as a rotatable connection. The angle of the housing 110 can be adjusted by rotating the support frame 130 relative to the housing 110, thereby adjusting the lighting direction to suit different supplementary lighting needs.

[0043] Please refer to Figure 3 and Figure 4 In this embodiment, an air outlet 131 is provided at the bottom of the support frame 130, and a cooling fan 140 is provided at the position of the air outlet 131. An air inlet 132 is provided on the side of the support frame 130 opposite to the air outlet 131. The air inlet 132, the air outlet 131, the air duct 111, and the through hole 121 form a through-ventilation duct 111, which, together with the cooling fan 140, forms a directional airflow path. Compared with traditional enclosed space heat dissipation, heat can be quickly discharged along the air duct 111, reducing heat accumulation inside the housing 110, reducing the risk of brightness decay, and extending the service life of the supplementary light 100 of this application.

[0044] In this application embodiment, the shape of the air outlet 131 can be selected in various ways. In a preferred embodiment, please refer to... Figure 3 The air outlet 131 has a circular design, which is compatible with the cooling fan 140, ensuring that airflow can pass through the air outlet 131 fully and improve operating efficiency. The shape of the air inlet 132 in this application is not limited.

[0045] The supplementary light 100 provided in this application embodiment has a housing 110 with an air duct 111 penetrating the top and bottom ends of the housing 110. The lamp head 120 has a through hole 121 in the middle that connects to the air duct 111. A support frame 130 is connected to the outer wall of the housing 110. An air outlet 131 and an air inlet 132 are provided at the bottom of the support frame 130. A cooling fan 140 is provided at the bottom of the support frame 130. The airflow generated by the cooling fan 140 passes through the air outlet 131, the air duct 111 and the through hole 121 in sequence, and finally acts on the external environment as a blower, which improves the heat dissipation path and thus improves the heat dissipation efficiency. The airflow through the air duct 111 carries away the heat of the heating component, which can reduce the heat accumulation inside the housing 110, reduce the risk of brightness decay, and extend the service life of the supplementary light 100. In addition, the lamp head 120 can be detachably connected to the housing 110 and can be used as a small supplementary light 100, which improves the practicality of the product.

[0046] In this application embodiment, the shape of the support frame 130 can be selected in various ways. In a preferred embodiment, please refer to... Figure 2 and Figure 3 The support frame 130 is U-shaped. The outer side wall of the housing 110 includes two opposing first side walls 115 and two opposing second side walls 112. The support frame 130 is movably connected to the two first side walls 115. The U-shaped support frame 130 facilitates the stable placement of the supplementary light 100 on a horizontal surface, and the two first side walls 115 of the housing 110 are movably connected to the support frame 130, which improves the ease of operation compared to single-point adjustment.

[0047] Please refer to Figure 2 To further enhance the heat dissipation flexibility of the supplementary lighting 100 of this application, each of the second sidewalls 112 is provided with multiple heat dissipation holes 1121. When the housing 110 is adjusted to meet the requirements of the supplementary lighting angle, the air duct 111 is deviated from the air outlet 131, and the airflow of the cooling fan 140 enters the interior of the housing 110 through the heat dissipation holes 1121, carrying away heat to achieve heat dissipation. Thus, the supplementary lighting 100 of this application can achieve the function of all-round heat dissipation.

[0048] In this application embodiment, the shape of the heat dissipation hole 1121 can be selected in various ways. In a preferred embodiment, please refer to [the following text is incomplete and requires further context]. Figure 2 The heat dissipation holes 1121 can be roughly in the shape of three stars, providing an opening for the flow of heat dissipation air while also improving the appearance of the product casing 110 and enhancing the aesthetic value of the product.

[0049] The fill light 100 provided in this application embodiment has a blower function that can blow cool air into the external environment, providing a cooling function. In a preferred embodiment, a cooling component is also provided inside the bottom of the support frame 130, and the cooling component is located close to the cooling fan 140. When the cooling component is activated, the airflow temperature generated by the cooling fan 140 is affected by it, and the outlet air temperature is reduced, which can further improve the heat dissipation and cooling performance, reduce the heat accumulation inside the housing 110, and can also be used as a cooling tool for emergency use by users, improving the expandability of the fill light 100 of this application.

[0050] In this application, various types of cooling components can be selected. In a preferred embodiment, the cooling component is a thermoelectric cooler. When energized, the thermoelectric cooler absorbs heat from its cold end and releases heat from its hot end. For example, the thermoelectric cooler is a thermocouple structure composed of N-type and P-type semiconductor materials. Because the thermoelectric cooler has no moving mechanical parts during its cooling process, it operates very quietly without wear and tear, resulting in high reliability. Moreover, the thermoelectric cooler is small in size and lightweight, making it suitable for integration into space-constrained devices, especially handheld or portable devices.

[0051] It should be noted that the principle of semiconductor cooling devices is existing technology and will not be elaborated here. The shape of the cooling device is not specifically limited here.

[0052] The fill light 100 provided in this embodiment also has a blower function that can blow hot air into the external environment, providing heating and drying functions. In a preferred embodiment, a heating element is also provided inside the bottom of the support frame 130, and the heating element is located close to the cooling fan 140. When the heating element is activated, the airflow temperature generated by the cooling fan 140 is affected by it, and the outlet air temperature rises. This can help adjust the airflow near the subject and fine-tune the ambient temperature during photography, solving the problem of the traditional fill light 100 having a single heat dissipation function.

[0053] In this application, the type of heating element can be selected from various embodiments. In a preferred embodiment, the heating element is a semiconductor heating plate. The principle of semiconductor heating elements is prior art and will not be described in detail here. The shape of the heating element is not specifically limited here.

[0054] In this application embodiment, there are multiple options for implementing the supplementary lighting angle adjustment. In a preferred embodiment, a drive motor is also provided inside the support frame 130, and the output end of the drive motor is connected to two rotating modules, which are respectively located at the connection between the support frame 130 and the two first side walls 115. Further, the rotating module includes a gear set, which is driven by the drive motor to rotate and automatically adjust the angle to adapt to different supplementary lighting angle requirements. For example, when the drive motor rotates forward, it can drive the housing 110 to adjust the angle in the horizontal direction (around the axial direction of the support frame 130); when the drive motor rotates in reverse, it can drive the housing 110 to adjust the angle in the pitch direction.

[0055] Please refer to Figure 6 The supplementary lighting 100 of this application embodiment has a lamp head 120 with a lamp board 160, on which light-emitting devices are disposed. A first power module electrically connected to the lamp board 160 is disposed within a housing 110. When the lamp head 120 is fixed to the housing 110, the first power module directly supplies power to the lamp board 160, thus providing a large supplementary lighting 100 to meet the needs of professional scenarios. In a preferred embodiment, the lamp board 160 can be an LED lamp board, and the light-emitting devices are multiple LED beads.

[0056] The supplementary light 100 provided in this embodiment also has a portable supplementary lighting function. A second power module is also provided on the light board. When the lamp head 120 is detached from the housing 110, it is powered by the second power module on the light board 160, allowing the lamp head 120 to emit light independently, providing portable supplementary lighting and emergency lighting functions, and improving the product's expandability.

[0057] In this application embodiment, there are multiple options for the implementation of the second power module. For example, the second power module can be a button battery as a backup power source for the lamp board 160, supporting the small lamp head 120 of the fill light 100 in this embodiment for portable scenarios, expanding the scope of application and improving the practicality of the product.

[0058] In some embodiments, please refer to Figure 5 A control module 150 is provided on one outer wall of the support frame 130. The control module 150 includes multiple buttons 151 and a display screen 152. The control module 150 is connected to the electronic control module. The multiple buttons 151 can control the light-emitting device to emit light, adjust the supplementary light angle, and switch between hot and cold air modes, etc. The display screen 152 can display the hot and cold air modes, etc., improving the ease of operation of the supplementary light 100 of this application.

[0059] In this embodiment of the application, the electronic control module may include a control chip, such as a microcontroller chip, which can preset a program to achieve automated control of various modules and components.

[0060] In this application, there are several options for the connection between the lamp holder 120 and the housing 110. In a preferred embodiment, please refer to... Figure 6 and Figure 7 The top of the housing 110 is provided with a first step 113, and the end of the air duct 111 facing the through hole 121 is provided with a second step 114. The peripheral wall of the through hole 121 extends toward the air duct 111 and is provided with a boss 122. When the lamp holder 120 is inserted into the housing 110, the outer side wall end of the lamp holder 120 abuts against the first step 113, and the boss 122 abuts against the second step 114, realizing the insertion and engagement, and facilitating the quick disassembly and use of the lamp holder 120.

[0061] In this application embodiment, the first step 113 can be configured in several ways. In a preferred embodiment, please refer to... Figure 7 The first step 113 is arranged around the periphery of the top of the housing 110. That is to say, the first step 113 is not a partial arrangement, but a complete arrangement around the periphery of the top of the housing 110, ensuring that the lamp head 120 and the housing 110 fit together in all directions and improving connection stability.

[0062] In this application embodiment, the second step 114 can be configured in several ways. In a preferred embodiment, please refer to [reference needed]. Figure 7 The second step 114 is arranged around the periphery of the air duct 111 port. That is to say, the second step 114 is not a partial arrangement, but a complete encirclement around the periphery of the end of the air duct 111, ensuring that the lamp head 120 and the housing 110 form a full-range fit, and cooperates with the first step 113 to further improve the connection stability.

[0063] In this embodiment, the shape of the lamp holder 120 can be chosen in various ways. For example, the end face of the lamp holder 120 can be a polygon with more than four sides, such as a pentagon or a heptagon. In a preferred embodiment, please refer to... Figure 1 The 120 lamp head has an octagonal end face, which further enhances the design, improves the product's aesthetic value and market recognition, and meets users' needs for personalized equipment.
