Description

TECHNICAL FIELD

[0001] The utility model relates to a lamp lighting technical field, concretely relates to a portable light supplementing lamp. BACKGROUND

[0002] At present, high-power light supplementing lamps are more and more required for personal studios and small teams for video shooting and live light supplementing. High-power light supplementing lamps not only require portability, but also have large power and high brightness, and different application fields of light supplementing lamps have different requirements. The existing high-power light supplementing lamps (for example, the power is 300W) have large heat generation when illuminating and light supplementing, in order to avoid the influence of heat generation of the light source on electronic components on the internal circuit board of the lamp body, a large-size heat sink and a fan need to be arranged in the lamp body to quickly discharge the heat generated by the light source to the outside.

[0003] At present, the lamp body of the high-power light supplementing lamp mainly includes a lamp shell, a light source plate, a heat sink, a fan and a circuit board arranged in the lamp shell. The front surface of the lamp shell is provided with a light outlet, and the light emitted by the light source is emitted outward through the light outlet. In order to preferentially ensure the heat dissipation effect, the size of the heat sink is usually close to the size of the lamp shell. Moreover, the light source plate, the heat sink, the fan and the circuit board are arranged side by side along the thickness direction of the lamp shell, and the light source plate, the heat sink, the fan and the circuit board are independently installed in the lamp shell respectively, which will result in that the thickness of the lamp body in the light emission direction is relatively large, and the high-power light supplementing lamp generally has poor portability. SUMMARY

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defects of the prior art that the high-power light supplementing lamp has large thickness in the light emission direction and poor portability, so as to provide a portable light supplementing lamp.

[0005] To solve the above technical problems, the technical scheme of the utility model is as follows:

[0006] A portable light supplementing lamp includes a lamp body, the lamp body includes a front shell module and a rear shell module connected along the thickness direction thereof, and a heat sink module arranged in the enclosed space of the front shell module and the rear shell module; the front surface of the front shell module is provided with a light outlet, the heat sink module includes a heat sink arranged opposite to the light outlet, a light source plate fixed on the side of the heat sink facing the light outlet, a fan embeddedly fixed on the side of the heat sink away from the light source plate, and a drive-PCBA board fixed on the side surface of the heat sink; the light emitted by the light source plate is emitted outward through the light outlet.

[0007] Furthermore, the heat sink is flat; the line connecting the light source board and the fan is in the thickness direction of the heat sink; the two opposite sides of the heat sink where the light source board and the fan are mounted are the two largest surfaces of the heat sink; the side of the heat sink where the driver-PCBA board is mounted is perpendicular to the largest surface of the heat sink.

[0008] Furthermore, an MCU-PCBA board electrically connected to the drive-PCBA board is installed inside the rear shell module; the MCU-PCBA board is located on the side of the heat sink facing away from the light outlet, and the MCU-PCBA board avoids the air outlet surface of the fan.

[0009] Furthermore, the driver-PCBA board is provided with an inductor and a first electrolytic capacitor, both of which are mounted on the side of the driver-PCBA board facing away from the heat sink.

[0010] Furthermore, the driver-PCBA board is also provided with a second electrolytic capacitor, which is installed on the side of the driver-PCBA board facing the heat sink. The heat sink has a recessed cavity at its top corner, and the second electrolytic capacitor extends into the recessed cavity of the heat sink.

[0011] Furthermore, the front housing module includes a front housing with a light outlet on the front side, an adapter ring disposed on the front side of the front housing and surrounding the light outlet, the adapter ring having a bayonet structure for detachable connection with a lamp accessory, and the front housing also having an unlocking key for locking or unlocking the lamp accessory and the adapter ring.

[0012] Furthermore, a screw hole fixing block is provided on the side of the front housing where the light outlet is not located, and the quick-release seat can be threadedly connected to the screw hole fixing block via the connecting screw on it.

[0013] Furthermore, the thickness of the lamp body is no greater than 74mm, the length of the lamp body is no greater than 163mm, and the width of the lamp body is no greater than 126mm; the lamp body includes a front and a back side enclosed by a long side and a wide side, and the light outlet is located on the front side of the lamp body.

[0014] Furthermore, the rear shell module also includes a rear shell, a display screen, a switch button, a CCT / M knob, a DIM / FN knob, and a metal ring; the display screen, the switch button, the CCT / M knob, and the DIM / FN knob are all connected to the MCU-PCBA board, the metal ring is positioned opposite the fan, and the metal ring is provided with heat dissipation air intake holes.

[0015] Furthermore, the maximum luminous power of the lamp body is not less than 250W, and the driver-PCBA board is also electrically connected to a power input interface.

[0016] The technical solution of this utility model has the following advantages:

[0017] 1. The portable fill light provided by this utility model directly fixes the light source board, fan, and driver-PCBA board onto the heat sink to form an integrated heat sink module. Since the light source board, fan, and driver-PCBA board are all in direct contact with the heat sink, the overall heat dissipation effect is better, meeting the rapid heat dissipation requirements of high-power fill lights. Furthermore, the structure of the fan embedded and fixed on the heat sink, compared to the existing technology where the fan and heat sink are arranged side-by-side in the light-emitting direction of the lamp body, reduces the space occupied by the fan in the light-emitting direction. While ensuring high-power illumination and adequate heat dissipation, this design helps to shorten the lamp body's dimensions in the thickness direction (i.e., the vertical direction of the light source board), thereby improving the lamp body's portability. In addition, the driver-PCBA board is directly mounted on the heat sink. Compared to the existing technology where the driver-PCBA board is mounted on the rear shell module, the driver-PCBA board can be closer to the heat sink, which is beneficial for improving the heat dissipation effect on the functional components on the circuit board assembly.

[0018] 2. The portable fill light provided by this utility model designs the circuit board inside the lamp body as two independent MCU-PCBA boards and a driver-PCBA board. The driver-PCBA board is mainly used for starting the LEDs on the light source board, while the MCU-PCBA board is mainly used for data processing, logic control, and signal acquisition. The MCU-PCBA board and the driver-PCBA board perform different functions respectively. Moreover, the size of a single PCBA board is smaller, and the installation is more flexible. The MCU-PCBA board and the driver-PCBA board can be set on two different sides of the heat sink, which is beneficial to fully utilize the heat dissipation capacity of different sides of the heat sink. Because of its small size, the MCU-PCBA board can easily avoid the fan's exhaust surface and will not block the fan's exhaust surface, which facilitates the fan to drive the air to flow quickly in the thickness direction of the lamp body, improving the heat dissipation effect. Compared with the layout of the prior art, where the lamp body only includes a single circuit board and the circuit board blocks the fan's exhaust surface, the heat dissipation effect is better. With a certain light source board luminous power, a smaller heat sink can be used for heat dissipation, and the size of the lamp body shell can also be reduced, which is beneficial to the portability of the lamp body. In addition, since the electronic components on the driver-PCBA board generate relatively much heat, mounting the driver-PCBA board separately on the side of the heat sink can fully utilize the heat dissipation capacity of the heat sink side and prevent the electronic components on the driver-PCBA board from overheating.

[0019] 3. The portable fill light provided by this utility model, since the inductor and the first electrolytic capacitor are relatively tall electronic components on the circuit board, by placing these relatively tall electronic components on the driver-PCBA board located on the side of the heat sink, the inductor and the first electrolytic capacitor will not occupy the installation space in the thickness direction of the lamp body. Compared with the existing technology where the relatively tall electronic components such as the inductor and the first electrolytic capacitor are directly mounted on the PCB board and occupy the installation space in the thickness direction of the lamp body, this is beneficial to shorten the thickness of the lamp body and improve the portability of the lamp body.

[0020] 4. In the portable fill light provided by this utility model, the second electrolytic capacitor on the driver-PCBA board is also a relatively tall electronic component. The second electrolytic capacitor is installed on the side of the driver-PCBA board facing the heat sink, and the second electrolytic capacitor extends into the cavity at the top corner of the heat sink. This arrangement can reduce the space occupied by the second electrolytic capacitor in the length direction of the lamp body, which is beneficial to shortening the length of the lamp body.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] like Figure 1 - Figure 2 The portable fill light shown includes a rectangular lamp body 100. The thickness of the lamp body 100 is no more than 74 mm, the length of the lamp body 100 is no more than 163 mm, and the width of the lamp housing portion of the lamp body 100 is no more than 126 mm. The overall width of the lamp body 100 (including the protruding power input interface 15 at the bottom of the lamp housing) does not exceed 134 mm. The maximum luminous power of the lamp body 100 is no less than 250 W.

[0039] For example, in some embodiments, the lamp body 100 has a thickness of 74mm, a length of 163mm, and a width of 126mm for the lamp housing portion; the overall width of the lamp body 100 (including the protruding power input interface 15 at the bottom of the lamp housing) is 134mm. The maximum luminous power of the lamp body 100 is not less than 300W. This lamp body 100 is one-third smaller in thickness and volume than a traditional 300W fill light, making it easy to store in a handbag and highly portable.

[0040] like Figure 1 - Figure 3 As shown, the lamp body 100 includes a front and a back surface enclosed by a long side and a wide side, and a side surface enclosed by a long side and a thick side or a wide side and a thick side. The front surface of the lamp body 100 has a light-emitting port, and the front, back, and side surfaces of the lamp body 100 all have heat dissipation holes. The lamp body 100 includes a front shell module 10 and a rear shell module 20 connected along its thickness direction, and a heat sink module 30 disposed within the space enclosed by the front shell module 10 and the rear shell module 20; the light-emitting port is located on the front surface of the front shell module 10.

[0041] like Figure 3 and Figure 4 As shown, the heat sink module 30 includes a heat sink 31 facing the light outlet, a light source plate 33 fixed to the side of the heat sink 31 facing the light outlet, a fan 32 embedded and fixed to the side of the heat sink 31 facing away from the light source plate 33, and a driver-PCBA board 35 fixed to the side of the heat sink 31; the light emitted by the light source plate 33 is emitted outward through the light outlet. It should be noted that the front is the side of the lamp body 100 with the light outlet, and the back is the side of the lamp body 100 facing away from the light outlet.

[0042] This portable fill light directly fixes the light source board 33, fan 32, and driver-PCBA board 35 to the heat sink 31 to form an integrated heat sink module 30. Since the light source board 33, fan 32, and driver-PCBA board 35 are all in direct contact with the heat sink 31, the overall heat dissipation effect is better, which can meet the rapid heat dissipation requirements of high-power fill lights. Moreover, the structure in which the fan 32 is embedded and fixed on the heat sink 31 can reduce the space occupied by the fan 32 in the light output direction of the lamp body 100 compared with the existing technology where the fan 32 and the heat sink 31 are arranged side by side in the light output direction of the lamp body 100. While meeting the requirements of high-power lighting and heat dissipation performance, the size of the lamp body 100 in its own thickness direction (that is, the vertical direction of the light source board 33) can be shortened, improving the portability of the lamp body 100. In addition, the driver-PCBA board 35 is directly mounted on the heat sink 31. Compared with the prior art, where the driver-PCBA board 35 is mounted on the rear shell module 20, the driver-PCBA board 35 can be closer to the heat sink 31 after installation, which is beneficial to improving the heat dissipation effect on the functional components on the circuit board assembly.

[0043] like Figure 1 - Figure 4 As shown, the front shell module 10 includes a front shell 11, a screw hole fixing block 12, an adapter ring 13, an unlock button 14, a power input interface 15, a lower pressure cover 16, a reflector cup 17, a glass plate 18, and an upper pressure cover 19.

[0044] like Figure 3 and Figure 4 As shown, the front housing 11 is a housing structure with an internal mounting cavity. The light outlet is located on the front of the front housing 11, and the back of the front housing 11 is open. The heat sink module 30 can be installed in the mounting cavity of the front housing 11. The rear housing 21 is connected to the open part on the back of the front housing 11, and the heat sink module 30 is located in the space formed by the front housing 11 and the rear housing 21.

[0045] like Figure 1 and Figure 4As shown, the screw hole fixing block 12 is located on the side of the front housing 11 where there is no light outlet. The quick-release bracket can be threaded onto the screw hole fixing block 12 via the connecting screw on it. This arrangement facilitates the mounting of the lamp body 100 onto the quick-release bracket on the top of the lamp holder or handle.

[0046] like Figure 4 As shown, the lower pressure cover 16 is fixed inside the front housing 11 and located on the side of the heat sink 31 facing the light outlet; the light source plate 33, the reflector cup 17 and the glass plate 18 are arranged coaxially, and the upper pressure cover 19 and the lower pressure cover 16 cooperate to clamp and fix the reflector cup 17 and the glass plate 18; the light emitted by the light source plate 33 shines outward through the transparent glass plate 18.

[0047] like Figure 4 As shown, the adapter ring 13 is integrally connected to the front of the front housing 11, and the adapter ring 13 is arranged around the light outlet; the adapter ring 13 is provided with a bayonet structure, which is used for detachable connection with lamp accessories, such as reflectors 17 (e.g., Figure 11 (As shown) or accessories such as softboxes. The front housing 11 is also provided with an unlocking button 14 for locking or unlocking between the lamp accessories and the adapter ring. The unlocking button 14 is elastically installed in the front housing 11 via a spring piece 141. The lamp accessories are detachably connected to the adapter ring 13, so that the lamp body 100 and various lamp accessories can be used in combination to improve the performance of the fill light.

[0048] like Figure 2 , Figure 4 and Figure 5 As shown, the rear housing module 20 includes a rear housing 21, a display screen 22, a switch button 23, a CCT / M knob 24, a DIM / FN knob 25, a metal ring 26, and an MCU-PCBA board 27. The MCU-PCBA board 27 is installed inside the rear housing 21, and the display screen 22, switch button 23, CCT / M knob 24, and DIM / FN knob 25 are all connected to the MCU-PCBA board 27. The switch button 23 is installed on the back of the rear housing 21, and the CCT / M knob 24 and DIM / FN knob 25 are installed on the side of the rear housing 21, and both the CCT / M knob 24 and DIM / FN knob 25 adopt an embedded design. The metal ring 26 is installed on the back of the rear housing 21, and the metal ring 26 is directly opposite the fan 32, and the metal ring 26 has heat dissipation air inlets. Using the metal ring 26 with heat dissipation air inlets as the air inlet of the lamp can improve the heat dissipation effect.

[0049] like Figure 5 - Figure 9As shown, the heat sink 31 is generally rectangular in shape. The line connecting the light source plate 33 and the fan 32 runs along the thickness direction of the heat sink 31. The thickness of the heat sink 31 is less than its length and width. The length, width, and thickness of the heat sink 31 correspond to the length, width, and thickness of the lamp body 100, respectively. The light source plate 33 and the fan 32 are respectively mounted on the two largest surfaces of opposite sides of the heat sink 31. The smaller thickness of the heat sink 31 helps to shorten the thickness of the lamp housing and improve the portability of the lamp body 100.

[0050] like Figure 5 - Figure 9 As shown, the MCU-PCBA board 27 and the driver-PCBA board 35 are electrically connected and independently configured. The MCU-PCBA board 27 and the driver-PCBA board 35 perform different functions. The driver-PCBA board 35 is mainly used for starting the LEDs on the light source board 33, while the MCU-PCBA board 27 is mainly used for data processing, logic control, and signal acquisition. The MCU-PCBA board 27 is located on the side of the heat sink 31 facing away from the light outlet, and it avoids the exhaust surface of the fan 32. The driver-PCBA board 35 is mounted on the side of the heat sink 31, with the side of the heat sink 31 on which the driver-PCBA board 35 is mounted perpendicular to the largest surface of the heat sink 31.

[0051] This configuration allows for smaller individual PCBA board sizes and more flexible installation. The MCU-PCBA board 27 is mounted on the side of the rear housing 21 facing the heat sink 31, allowing the MCU-PCBA board 27 and the driver-PCBA board 35 to be located on two different sides of the heat sink 31. This maximizes the heat dissipation capacity of the heat sink 31's sides. Furthermore, the smaller size of the MCU-PCBA board 27 avoids obstructing the airflow from the fan 32, facilitating rapid airflow along the thickness of the lamp body 100 and improving heat dissipation. Compared to existing designs where the lamp body contains only a single circuit board that blocks the fan 32's airflow, this configuration offers significantly better heat dissipation. With a fixed luminous power of the light source board 33, a smaller heat sink 31 can be used for heat dissipation, reducing the overall size of the lamp body 100 and improving its portability. In addition, since the electronic components on the driver-PCBA board 35 generate relatively large amounts of heat, mounting the driver-PCBA board 35 separately on the side of the heat sink 31 can fully utilize the heat dissipation capacity of the side of the heat sink 31 and prevent the electronic components on the driver-PCBA board 35 from overheating.

[0052] like Figure 5 - Figure 9As shown, a first electrolytic capacitor 352 and an inductor 351 are provided on the driver-PCBA board 35, both mounted on the side of the driver-PCBA board 35 facing away from the heat sink 31. Since the first electrolytic capacitor 352 and inductor 351 are relatively tall electronic components on the circuit board, placing these components on the driver-PCBA board 35 located on the side of the heat sink 31 avoids occupying mounting space in the thickness direction of the lamp body 100. Compared to the prior art where these tall electronic components are directly mounted on the PCB board and occupy mounting space in the thickness direction of the lamp body 100, this arrangement helps to shorten the thickness of the lamp body 100 and improve its portability.

[0053] like Figure 5 - Figure 9 As shown, a second electrolytic capacitor 353 is also provided on the driver-PCBA board 35. The second electrolytic capacitor 353 is installed on the side of the driver-PCBA board 35 facing the heat sink 31. A cavity is provided at the top corner of the heat sink 31, and the second electrolytic capacitor 353 extends into the cavity of the heat sink 31. Since the second electrolytic capacitor 353 on the driver-PCBA board 35 is also a relatively tall electronic component, this arrangement of the second electrolytic capacitor 353 can reduce the space occupied by the second electrolytic capacitor 353 in the length direction of the lamp body 100, which is beneficial to shortening the length of the lamp body 100.

[0054] Figure 10 The power supply box 210 is used in conjunction with the lamp body 100. One end of the power supply box 210 is connected to a power supply socket 220, and the other end is connected to a power plug 230. The power supply socket 220 is used to connect to the power input interface of the lamp body 100, and the power plug 230 is used to connect to a power socket. The lamp body 100 can be connected to an external power source for use through the power supply box 210.

[0055] Figure 11 The V-port battery 300 is used in conjunction with the lamp body 100. The V-port battery 300 is connected to the lamp body 100 through the V-port cable 400. The V-port battery 300 continuously supplies power to the lamp body 100 to meet the long-term battery life requirements of the fill light.

[0056] Figure 12This is a schematic diagram of the assembly of the lamp body 100, reflector 600, and handle 500. A tilt head is mounted on the top of the handle 500. The tilt head includes a pair of hinge seats rotatably connected around a hinge axis, and a locking knob connected to the hinge axis for securing the pair of hinge seats. A quick-release bracket is detachably connected to one of the hinge seats, and the quick-release bracket has a connecting screw for threaded connection with the screw hole fixing block 12. During assembly, first install the quick-release bracket on the screw hole fixing block 12 at the bottom of the lamp body, then install the quick-release bracket on the tilt head, and finally fix the tilt head to the top of the handle 500. This allows the lamp body 100 to be fixed to the handle for use via the quick-release bracket and the tilt head. This portable fill light can be used by hand holding the handle 500. During handheld use, the tilt angle of the lamp body 100 can be adjusted via the tilt head to meet the needs of focused fill light at small angles. A reflector 600 is installed on the adapter ring 13 of the lamp body 100. The smaller end of the reflector 600 has a reflector slot, which is detachably connected to the slot structure of the adapter ring 13.

[0057] In summary, the portable fill light provided by this utility model has the advantages of small size, high power, portability, and rich functional accessories; it can be fixed on the handle or used handheld, with sufficient power to meet the fill light needs of various photography environments, a high brightness of 300W, and the brightness can be adjusted from 0 to 100%, which can easily and instantly improve the fill light brightness; at the same time, it can also be equipped with different functional accessories to achieve special fill light applications according to individual needs.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
