[0039] The preferred embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0040] This application provides a power control device 1 for a flash unit, used to supply power to a high-power flash unit. The flash unit typically has a power output of several kilowatts, an operating current of 30A or more, and an operating voltage of 600V or more.

[0041] Please see Figure 1 to Figure 3 . Figure 1 This is a structural diagram of a power control device 1 according to an embodiment; Figure 2 This is a structural diagram of an embodiment where part of the casing 10 and the internal structure of the power control device 1 are hidden. Figure 3 yes Figure 2 A structural diagram from another perspective.

[0042] In one embodiment, the power control device 1 for the flash includes a housing 10, a power supply unit 20, and a power control unit 30. The housing 10 has a connection interface 15 for electrical connection to the flash; a laterally extending heat dissipation duct is formed inside the housing 10 (see corresponding...). Figure 3 (The middle arrow indicates the direction); the power supply unit 20 is electrically connected to the connection interface 15 to supply power to the flash lamp through the connection interface 15. The power supply unit 20 includes an energy storage module 21 and a discharge control board assembly electrically connected to the connection end of the energy storage module 21; the discharge control board assembly is located in the heat dissipation duct; the power control unit 30 is electrically connected to the discharge control board assembly to control the discharge of the energy storage module 21; the power control unit 30 is disposed on the upper layer of the power supply unit 20 and is located in the heat dissipation duct.

[0043] In a specific example, with Figure 1 Taking the orientation as an example, the casing 10 is roughly rectangular and has four side plates. The left and right side plates have heat dissipation mesh holes 131, thus forming heat dissipation airflow channels. These airflow channels extend roughly horizontally. The heat dissipation mesh holes 131 can be honeycomb-shaped, and each mesh unit can be hexagonal, pentagonal, or circular.

[0044] In one embodiment, the power control device 1 of the flash lamp further includes a cooling fan 50, which is fixed on the housing 10 and is provided with corresponding heat dissipation mesh 131. The air blowing direction of the cooling fan 50 is along the heat dissipation duct direction.

[0045] Please see Figure 4 and Figure 5 , Figure 4 yes Figure 2 , Figure 3 Exploded view of the partial structure shown. Figure 5 yes Figure 4Figure 2 is a structural exploded view of one side plate of the middle casing 10. Specifically, the casing 10 is a two-layer structure, including a main casing 13 and a decorative plate 12 arranged outside the main casing 13. The main casing 13 and the decorative plate 12 are both provided with the heat dissipation mesh holes 131 at corresponding positions. Figure 4 Figure 3 is a structural exploded view of the main casing 13.

[0046] In one embodiment, the power control device 1 of the flash lamp further includes a filter cotton 14, which is arranged between the main casing 13 and the decorative plate 12 and corresponds to the heat dissipation mesh holes 131. The filter cotton 14 is used to filter the air entering the casing 10, so as to reduce the amount of particulate matter carried in the air and avoid the particulate matter from being deposited on the electronic devices to cause the electronic devices to malfunction, thereby improving the stability of the power control device 1.

[0047] In one embodiment, the power control device 1 of the flash lamp further includes a heat dissipation fan 50, which is fixed on the casing 10 and corresponds to the heat dissipation mesh holes 131, and the blowing direction of the heat dissipation fan 50 is along the air duct direction. The heat dissipation fan 50 is used to increase the air volume and air speed entering from the heat dissipation mesh holes 131, so as to improve the heat dissipation capacity of the casing 10 by sucking in the air with lower temperature into the casing 10 and quickly blowing out the heat from the casing 10. In this embodiment, the fan is fixed on the main casing 13, so as to maximize the air volume.

[0048] Due to the diffusion of the air, the height of the actually formed air duct is greater than the height of the heat dissipation mesh holes 131, and the width of the actually formed air duct is greater than the width of the heat dissipation mesh holes 131. By selecting the heat dissipation fan 50 with larger power and longer blades, the coverage of the heat dissipation fan 50 can be further improved. Specifically, the height of the actually formed air duct is about 2-3 times the height of the heat dissipation mesh holes 131, and the width of the actually formed air duct is about 2-3 times the width of the heat dissipation mesh holes 131.

[0049] The casing 10 is provided with a connection interface 15 for electrically connecting the flash lamp. The connection interface 15 can be a plug interface, and a control switch can be arranged on the power control device 1. When the connector of the flash lamp is inserted into the connection interface 15, the control switch is pressed to control the power control device 1 to supply power to the flash lamp.

[0050] The power is supplied by a power supply unit 20. The energy storage module 21 in the power supply unit 20 can include one or more energy storage capacitors 212. The plurality of energy storage capacitors 212 can be connected in series and / or parallel to increase the amount of stored energy. In this embodiment, the energy storage capacitors 212 are arranged at the bottom due to their large volume and weight, so as to improve the structural stability of the power control device 1.

[0051] Generally, the top of the energy storage capacitor 212 is provided with a connection end, which can be a charging end or a discharging end. In the embodiment, only the case of discharging the capacitor is discussed, and at this time the connection end can be regarded as a discharging end.

[0052] Please refer to Figure 4 and Figure 6 wherein Figure 6 is Figure 4 an exploded view of part of the structure. The discharge control board assembly is arranged above the energy storage module 21 and is electrically connected to the energy storage module 21. The discharge control board assembly is used to control the discharge of the energy storage capacitor 212. For example, it controls the start or stop of the discharge of the energy storage capacitor 212, and controls the duration of the discharge of the energy storage capacitor 212.

[0053] In an embodiment, the discharge control board assembly includes a switch control board 22, which includes a PCB board and a switch circuit arranged on the PCB board. The switch circuit includes a switching device 221, which can be an IGBT, a MOS tube, etc. Illustratively, in the state that the flash lamp is plugged into the connection interface 15, a power supply circuit is formed between the flash lamp and the energy storage module 21, the switching device 221 is connected in series in the power supply circuit, and is controlled by the power supply control unit 30. The on / off of the switching device 221 can control the on / off and the duration of conduction of the power supply circuit; by controlling the duty cycle of the control signal of the switching device 221, the voltage in the power supply circuit is controlled, so as to adjust the brightness of the flash lamp.

[0054] Further, the discharge control board assembly also includes a current limiting circuit board 23, which is a PCBA board, and a switching switch and a plurality of current limiting resistors 231 are arranged on the PCBA board. The current limiting circuit board 23 is electrically connected to the connection end of the energy storage module 21. When the flash lamp does not need a large power supply voltage in some modes, the switching switch can be controlled to be opened, and part of the current output by the energy storage module 21 flows through the current limiting resistors 231 and is consumed by the current limiting resistors 231, thereby reducing the voltage output by the energy storage module 21 to the flash lamp, to adapt to the application needs of the flash lamp.

[0055] In the embodiment, considering that the switching device 221 generates a large amount of heat during operation, and the current limiting resistors 231 also generate a large amount of heat when current flows through them, the switch control board 22 and the current limiting circuit board 23 are arranged side by side in the horizontal direction, so that there is a large gap between the switching device 221 and the current limiting resistors 231, to improve the heat dissipation performance of the discharge control board assembly.

[0056] In order to further improve the heat dissipation performance of the power supply unit 20, in an embodiment, the power supply unit 20 further comprises a metal flow guide sheet 24, which is electrically connected with the connecting end of the energy storage module 21 to conduct the current output by the energy storage module 21 to the discharge control board assembly; the metal flow guide sheet 24 is located in the heat dissipation air duct and is consistent with the extension direction of the heat dissipation air duct.

[0057] The metal flow guide sheet 24 is in the form of a sheet, and the material thereof can be copper or aluminum. The current output by the energy storage module 21 flows to the discharge control board assembly through the metal flow guide sheet 24. The metal flow guide sheet 24 has a large area and strong conductivity, which is conducive to improving the electrical connection stability of the energy storage module 21 and the discharge control board assembly. Moreover, it is conducive to reducing the local overheating condition generated in the process of current flowing from the energy storage module 21 to the discharge control board assembly. Moreover, the metal flow guide sheet 24 is in contact with the energy storage module 21 and the discharge control board assembly, and can dissipate heat for the energy storage module 21 and the discharge control board assembly through the heat conduction effect.

[0058] In an embodiment, the energy storage module 21 has a plurality of mounting columns 2111, the metal flow guide sheet 24 is provided with a plurality of first connecting holes 241, and the discharge control board assembly is provided with a plurality of second connecting holes 222; the positions of the mounting columns 2111, the second connecting holes 222 and the first connecting holes 241 correspond one by one; the mounting columns 2111 are correspondingly arranged in the first connecting holes 241 and the second connecting holes 222 to fixedly connect the discharge control board assembly, the metal flow guide sheet 24 and the energy storage module 21.

[0059] The energy storage module 21 can comprise a plurality of energy storage capacitors 212 and a capacitor fixing support 211 arranged on the capacitors, the capacitor fixing support 211 being used for fixing and limiting the plurality of energy storage capacitors 212. The mounting holes 2111 are arranged on the capacitor fixing support 211.

[0060] The metal flow guide sheet can be a whole metal sheet. In an embodiment, the metal flow guide sheet comprises a plurality of metal sheets, the plurality of metal sheets are arranged side by side along the horizontal direction, and there is a gap between adjacent metal sheets to allow the air in the heat dissipation air duct to flow through the gap, thereby improving the heat dissipation capability for the energy storage capacitors 212. Moreover, if a certain energy storage capacitor 212 fails, the corresponding metal sheet can be flexibly disassembled in this embodiment to repair or replace the energy storage capacitor 212, thereby facilitating the operation of the maintenance personnel.

[0061] As before, the power control unit 30 is arranged on the upper layer of the power supply unit 20 and located in the heat dissipation air duct. The power control unit 30 comprises a power control board 31 and a power board support 34 for fixing the power control board 31. The power control board 31 is a PCBA board. In an embodiment, the power control board 31 has surge protection circuit, PFC circuit and DC conversion circuit. These circuits are used to charge the energy storage module 21. And the power control board 31 has a master control chip, which outputs a switching control signal to the switching device 221 on the switching control board 22 to control the on-off of the switching device 221.

[0062] Because the power control board 31 has more circuits and has transformer devices, the heat generated is large. In an embodiment, the power control device 1 of the flash light further comprises a heat sink 32, which is installed on the power control board 31 and located in the heat dissipation air duct to dissipate heat for the power control board 31.

[0063] The heat sink 32 can be a finned heat sink 32, and multiple heat sinks 32 can be arranged. In an embodiment, the power control board 31 is located in the heat dissipation air duct and in an area with large air flow rate. In this embodiment, the power control board 31 is fixed on the casing 10 by the power board support 34.

[0064] In an embodiment, the power control board 31 has a mounting gap 33 formed on the edge thereof; and the above-mentioned heat dissipation fan 50 is fixed on the casing 10 and protrudes into the mounting gap 33. The arrangement of this embodiment makes the air outlet center of the heat dissipation fan 50 substantially flush with the power control board 31, so that part of the air outlet of the heat dissipation fan 50 blows above the power control board 31 to dissipate heat for the components above the power control board 31, and the other part of the air outlet blows below the power control board 31 to dissipate heat for the components below the power control board 31. This embodiment improves the air flow circulation in the casing 10, reduces the occurrence of heat accumulation, and the better air flow circulation is conducive to improving the heat dissipation performance, so that the excessively high temperature in the casing 10 is timely inhibited or reduced.

[0065] Further, the top of the casing 10 is provided with an operation assembly 40; the power control device 1 further comprises an operation control board 41 electrically connected with the operation assembly 40 and an operation board fixing support; and the operation control board 41 is arranged on the upper layer of the power control unit 30. The operation assembly 40 is used for operation to input control instructions to the power control device 1. The operation assembly 40 includes but is not limited to display screen, key, knob, etc. The operation control board 41 is fixed on the casing 10 by the operation board fixing support.

[0066] The operation control board 41 is used to generate a trigger signal to the power control unit 30 according to the triggering condition of the operation assembly 40; and is used to receive display information sent by the power control unit 30 to control the display screen to display.

[0067] The power control device 1 of the present application reduces the degree of heat collection of the discharge control board assembly, the power control unit 30 and the operation control board 41, and reduces the occurrence of local heat accumulation, thereby facilitating heat dissipation. The power control device 1 of the present application is provided with a layered structure, so that the discharge control board assembly and the power control unit 30 can be located in the heat dissipation air duct in parallel, thereby improving the heat dissipation efficiency. Therefore, the power control device 1 of the present application has better heat dissipation capacity, and is beneficial to improve the working stability.

[0068] The embodiment also provides a flash lamp assembly, which comprises a flash lamp and the power control device 1 of the flash lamp. The flash lamp can be a xenon lamp. The specific embodiment of the power control device 1 of the flash lamp is described in the above embodiment.
