In particular, when describing "a certain element", the present application does not limit the number of such elements to one, and may also include a plurality of them.

[0023] Please refer to Figures 1 to 7 As shown, the present application provides a photographic lamp 10, which can be applied to photographic auxiliary equipment, such as a COB photographic lamp. The photographic lamp 10 includes a main body portion 12 and a mounting fitting 14 and a locking device provided on the main body portion 12. Among them, the main body portion 12 is integrally square in structure and has six surfaces, namely a front surface M1, a rear surface M2, a left surface M3, a right surface M4, an upper surface M5, and a lower surface M6. The front surface M1 of the main body portion 12 is the surface for installing the lamp head 60, that is, the front surface M1 is the surface facing the object to be illuminated. The rear surface M2 of the main body portion 12 is the surface facing the user. The main body portion 12 includes a housing 18 and a plurality of components provided in the housing 18. The six surfaces of the main body portion 12 are the six surfaces of the housing 18, and the six side walls of the housing 18 are respectively provided corresponding to the six surfaces. The mounting fitting 14 is fixedly provided in the upper region of the rear surface M2 of the housing 18, for example, fixed on the housing 18 by means of screws.

[0024] Among them, the installation fitting 14 is fixedly arranged at the rear side of the main body part 12, and the locking device is arranged between the installation fitting 14 and the outer shell 18. Specifically, the locking device includes a button 20, a locking tongue 22, and a transmission assembly connected between the button 20 and the locking tongue 22. The locking tongue 22 and the transmission assembly are both arranged inside the outer shell 18. The button 20 is pressably arranged on the right side wall of the outer shell 18 and is close to the rear side wall of the outer shell 18. The button 20 is arranged on the right side of the main body part 12 and has a pressing direction a. For example, the button 20 is arranged on the right side surface M4 of the main body part 12, and the pressing direction a is, for example, horizontally to the left. One end of the locking tongue 22 is provided with a locking block 26. The locking block 26 movably penetrates through the installation fitting 14. The locking tongue 22 can move relative to the installation fitting 14 between a locking position and an unlocking position and drive the locking block 26 to control the switching of the installation fitting 14 between a locked state and an unlocked state. And the locking device is configured such that pressing the button 20 along the pressing direction can drive the locking tongue 22 to move from the locking position to the unlocking position along a direction opposite to the pressing direction a (horizontally to the right) through the transmission assembly. The locking device designed in this application can realize the unlocking method for the right side of the installation fitting 14. Pressing the button 20 causes the locking tongue 22 to be stressed in the opposite direction to obtain unlocking, satisfying the use scenario of unlocking with a right-side button and conforming to the ergonomic design. Specifically, the button 20 and the locking tongue 22 are connected to both ends of the transmission assembly, and the button 20 is located below the locking tongue 22. The transmission assembly can perform a rotational movement. Pressing the button 20 to the left drives the transmission assembly to rotate clockwise, thereby driving the locking tongue 22 to move to the right and exit the locking area of the installation fitting 14, and the unlocking of the external fitting installed on the installation fitting 14 can be realized. The specific locking and unlocking structures and the locking and unlocking methods of the locking device will be described in detail below.

[0025] Please also refer to Figures 3 to 6 As shown, the installation fitting 14 is provided with a slot 24 for plugging in an external fitting. The external fitting is, for example, a power adapter, etc. A plug-in part adapted to the slot 24 can be arranged on the power adapter. In this embodiment, the slot 24 is arranged on the outer surface of the installation fitting 14, and the slot 24 is a through slot structure extending from top to bottom. The slot 24 has a plugging direction. According to the illustrated direction, the plugging direction is the vertically downward direction. Preferably, the width of the slot 24 gradually decreases along the plugging direction, for example, in the shape of an isosceles inverted trapezoid. Further, the width of the slot 24 gradually decreases in the direction away from the outer shell 18, that is, the opposite side walls in the width direction of the slot 24 are inclined plane structures, so that after the external fitting is plugged into the slot 24, the external fitting can be limited in the front-back direction due to the limiting effect of the inclined plane structure, preventing the external fitting from disengaging from the slot 24 outward.

[0026] In the illustrated embodiment, the locking block 26 is provided on the rearward side of the right end of the locking tongue 22. A through opening 30 adapted to the locking block 26 is provided on the right side wall of the slot 24. The locking tongue 22 can move left and right relative to the mounting fitting 14 between a locked position and an unlocked position. Among them, when the locking tongue 22 is in the unlocked position, the locking block 26 protrudes into the through opening 30. At this time, the mounting fitting 14 is in the unlocked state. For example, the locking block 26 exits from the external fitting and protrudes into the through opening 30, and at the same time exits the slot 24, realizing the unlocking of the external fitting, so that the external fitting can be removed from the slot 24; when the locking tongue 22 is in the locked position, the locking block 26 disengages from the through opening 30 and protrudes into the slot 24. At this time, the mounting fitting 14 is in the locked state. For example, the external fitting can be locked by inserting the locking block 26 into the external fitting, so that the external fitting is fixed relative to the main body portion 12.

[0027] Further, a sliding groove 28 is provided on the side of the mounting fitting 14 facing away from the slot 24. The sliding groove 28 extends horizontally in the horizontal direction. The sliding groove 28 is arranged parallel to the pressing direction a and is perpendicular to the slot 24. The locking tongue 22 is slidably arranged in the sliding groove 28. An avoidance hole 31 is provided on the right bottom wall of the sliding groove 28. The avoidance hole 31 communicates with the through opening 30. The avoidance hole 31 is used to avoid the locking block 26, so that the locking block 26 can extend into the slot 24 or the through opening 30 through the avoidance hole 31. The locking block 26 is arranged to be movable left and right in the through opening 30 and the avoidance hole 31. The sliding groove 28 communicates with the slot 24 through the avoidance hole 31 and the through opening 30. When the locking tongue 22 is in the locked position, the locking block 26 protrudes into the slot 24 through the avoidance hole 31. When the locking tongue 22 is in the unlocked position, the locking block 26 is hidden in the through opening 30 on the right side wall of the slot 24.

[0028] Preferably, the locking device further includes an elastic member 32. The elastic member 32 is, for example, a spring. The elastic member 32 is arranged between the right end of the locking tongue 22 and the right end wall of the sliding groove 28, and the elastic member 32 applies an elastic biasing force to the locking tongue 22 to move it toward the locked position. Optionally, a limiting groove 34 is provided at the right end of the locking tongue 22. One end of the elastic member 32 close to the locking tongue 22 is elastically abutted in the limiting groove 34. Such an arrangement can prevent the elastic member 32 from disengaging from the sliding groove 28 during use.

[0029] In the illustrated embodiment, the transmission assembly is disposed in the housing 18 and is located on the front side of the mounting accessory 14. The transmission assembly includes a push rod 36 and a push block 38, wherein the push rod 36 is arranged in a horizontal direction, the push rod 36 has a relative fixed end 40 and a first rotating connection end 42, the push block 38 is rotatably connected to the mounting accessory 14 and has a relative second rotating connection end 44 and a driving end 46, the fixed end 40 is fixedly connected to one end of the button 20 located in the housing 18, for example, fixed by a snap-on connection, the button 20 is pressably arranged on the right side wall of the housing 18, the first rotating connection end 42 is rotatably connected to the second rotating connection end 44, for example, a rotating shaft 48 is arranged between the first rotating connection end 42 and the second rotating connection end 44, so that the push rod 36 and the push block 38 can realize relative rotation through the rotating shaft 48, and the driving end 46 is drivingly connected to the lock tongue 22.

[0030] Preferably, the driving end 46 is provided with a driving hole 50, and the driving hole 50 extends along the length direction of the push block 38. The front side of the end of the lock tongue 22 away from the locking block 26 is provided with a driving wheel 52, and the driving wheel 52 can be slidably driven to fit in the driving hole 50. The front side of the mounting accessory 14 is provided with a fixed shaft 54, and the push block 38 is provided with an axial hole 56, and the axial hole 56 is located between the second rotating connection end 44 and the driving end 46. For example, the axial hole 56 is provided in the middle position of the push block 38, and the push block 38 is rotatably sleeved on the fixed shaft 54 ​​through the axial hole 56, so that the push block 38 can be rotatably connected to the mounting accessory 14. At the same time, according to needs, by adjusting the position of the axial hole 56, different pressing strokes and lock tongue movement stroke ratios can be obtained by using the lever principle. A support member 58 is also fixed in the housing 18, and the support member 58 can be fixed on the inner wall of the housing 18 or fixed on the components in the housing 18, and the push rod 36 can be slidably connected to the support member 58.

[0031] In normal state, the locking block 26 protrudes into the slot 24. At this time, the external accessory can be inserted into the slot 24. During the downward insertion process, the external accessory will contact the locking block 26 and overcome the elastic pressure of the elastic member 32, so that the locking block 26 moves to the right and exits the slot 24. After the external accessory is inserted into the slot 24, the locking block 26 moves to the left under the elastic bias of the elastic member 32 and inserts the external accessory to achieve locking. When unlocking is required, the button 20 is pressed along the pressing direction a and drives the push rod 36 to move to the left. The push rod 36 drives the push block 38 to rotate clockwise and drives the lock tongue 22 to move to the right at the same time, so that the locking block 26 exits from the external accessory and the slot 24 at the same time, and the locking of the external accessory is released. At this time, the external accessory can be removed. After the external accessory is removed, the locking block 26 moves to the left under the elastic bias of the elastic member 32 and protrudes into the slot 24.

[0032] In the traditional COB photographic lamp, its brightness and light spot can only depend on the lamp beads themselves. It is impossible to mix light sources of multiple colors, and the formed light spot is uneven. It cannot converge the light to achieve the ideal light angle required for photography, resulting in insufficient brightness. In this embodiment, as Figure 2 shown, the main body part 12 includes a lamp head 60 provided on the front surface M1 of the outer shell 18. A lamp body 62 for emitting light is provided inside the lamp head 60. The lamp body 62 is, for example, a lamp bead. The lamp head 60 is provided with a plano-concave lens 64 and a fogging lens 66 on the light-emitting path of the lamp body 62. Among them, the fogging lens 66 is located between the plano-concave lens 64 and the lamp body 62. The light emitted by the lamp body 62 passes through the optical combination of the plano-concave lens 64 and the fogging lens 66, and the light angle of the lamp body 62 can be converged to the most preferred photographic angle, improving the brightness of the light, and at the same time, the light spot becomes more uniform. In some other embodiments, only the plano-concave lens 64 or the fogging lens 66 can also be provided. In this application, by installing the plano-concave lens 64 and the fogging lens 66 in front of the lamp body 62, the fogging lens 66 can mix light sources of multiple colors, so that the light emitted by the photographic lamp 10 has a uniform light spot and there will be no mottled or uneven situation. Since the light-emitting angle of the COB light source is relatively wide, generally reaching 102 degrees or even wider, but in actual application, the light in the range exceeding 80 degrees has exceeded the shooting view range, and the light outside the range is a waste in terms of utilization rate. By installing the plano-concave lens 64 in front of the fogging lens 66, it has the function of converging light, and the light outside 80 degrees can be converged within the effective angle range, improving the brightness within the effective range.

[0033] When adjusting the light angle of the traditional COB photographic lamp, after loosening the fastening device of the COB photographic lamp and the support column, due to the weight of the COB photographic lamp, it will rotate rapidly, and the uncontrollable rapid rotation affects the shooting and may even cause collision damage to the photographic equipment. In this embodiment, as Figure 2 and Figure 7 shown, the photographic lamp 10 further includes a lamp holder 68. The lamp holder 68 is provided at the bottom of the main body part 12. For example, the lamp holder 68 is detachably connected to the lower surface M6 of the main body part 12 and is used to support and fix the main body part 12. Specifically, the lamp holder 68 includes a lamp holder upper seat 70, a lamp holder lower seat 72, a fastening handle 74 and a damping member 76. The top end of the lamp holder upper seat 70 is fixedly connected to the main body part 12, for example, by screws. The lamp holder upper seat 70 is rotatably connected to the lamp holder lower seat 72, so that the shooting angle of the main body part 12 can be adjusted by rotating the lamp holder upper seat 70. The fastening handle 74 is provided on one side of the lamp holder upper seat 70 and is used to fasten or release the fastening relationship between the lamp holder upper seat 70 and the lamp holder lower seat 72. The damping member 76 is provided at the rotational connection of the lamp holder upper seat 70 and the lamp holder lower seat 72.

[0034] In the shown embodiment, as Figure 7As shown, the damping member 76 is provided as a damping rotating shaft. More specifically, the upper lamp holder 70 includes two connecting plates 78 arranged at intervals. A pivoting position 80 is formed between the two connecting plates 78, and coaxial connecting holes 82 are provided on both of the two connecting plates 78. The lower lamp holder 72 includes a rotating part 84, and the rotating part 84 is provided with a pivoting hole 86. The fastening handle 74 is provided with a fastening device 88. The damping rotating shaft includes a shaft portion 90 and a fixing portion 92 connected to one end of the shaft portion 90. During installation, the rotating part 84 extends into the pivoting position 80, and the fastening device 88 passes through the corresponding connecting hole 82 and pivoting hole 86, so that rotating the fastening handle 74 can realize the pressing and fixing of the rotating part 84 and the connecting plate 78 through the fastening device 88 and release the fastening relationship, thereby realizing the fastening or loosening between the upper lamp holder 70 and the lower lamp holder 72. When fastened, the two are relatively fixed and cannot rotate relative to each other. When loosened, the two can rotate relative to each other; the damping rotating shaft is arranged on the other side opposite to the fastening handle 74. At least one flat surface and one arc surface are arranged on the outer side surface of the shaft portion 90, so as to increase the rotation resistance between the upper lamp holder 70 and the lower lamp holder 72. The shape of the part of the pivoting hole 86 connected to the shaft portion 90 is adapted to the shape of the shaft portion 90. During installation, the shaft portion 90 is passed through the corresponding connecting hole 82 and inserted into the pivoting hole 86, and the fixing portion 92 is fixedly connected to the corresponding connecting plate 78, for example, fixed by screws. Preferably, a connecting accessory 16 is further fixed outside the connecting plate 78 on one side of the damping rotating shaft for connecting external accessories, and the connecting accessory 16 covers the damping rotating shaft. By providing the damping rotating shaft, it is possible to effectively prevent the main body part 12 from suddenly rotating and sliding down, playing a role in anti-collision and enhancing the protection effect on the photographic lighting fixture 10. Since the damping rotating shaft increases the rotation resistance, the main body part 12 needs to be rotated under a certain external force, and the damping degree of the damping rotating shaft can be flexibly matched according to needs to achieve a suitable damping feel and improve the photographic experience.

[0035] In summary, the present application provides a photographic lighting fixture, including a main body part, a mounting accessory and a locking device provided on the main body part. The mounting accessory is fixedly arranged at the rear side of the main body part. The locking device includes a button, a locking tongue and a transmission component connected between the button and the locking tongue.
