Referring to
The lamp body 10, as a lighting member, emits light outwards to illuminate the object. Optionally, a light source is disposed in the lamp body 10 and emits light outwards.
The first supporting arm 20 is rotatably connected to a sidewall of the lamp body 10 and rotates in a plane parallel to the sidewall of the lamp body 10 around with a rotation axis O1 which is perpendicular to the sidewall of the lamp body 10. In this embodiment, the first supporting arm is connected to the bottom sidewall of the lamp body 10 and rotates 360 degrees in a horizontal plane.
When the first supporting arm 20 rotates relative to the lamp body 10, the first supporting arm 20 may be placed below the bottom sidewall of the lamp body 10 (as shown in
The first supporting arm 20 and the sidewall of the lamp body 10 are connected by a first rotating seat 40. The first rotating seat 40 may be fixedly connected to the sidewall of the lamp body 10, and an end of the first supporting arm 20 may be rotatably sleeved on the first rotating seat 40. In this way, the first supporting arm 20 rotates relative to the lamp body 10 around with the first rotating seat 40 as the rotation axis O1 thereof, adjusting an angle between the first supporting arm 20 and the lamp body 10.
The first rotating seat 40 is disposed at an end of the sidewall of the lamp body 10, which facilitates rotation of the first supporting arm 20 relative to the lamp body 10 in the horizontal plane, and improves a rotation angle of the first supporting arm 20 relative to the lamp body 10. In this embodiment, a dovetail groove 22 is defined in a middle portion of the first rotating seat 40. The dovetail groove 22 is concaved at a side of the first rotating seat 40 away from the lamp body 10, for connecting the photographic lamp 100 to other members of the photographic equipment.
The second supporting arm 30 is rotatably connected to the first supporting arm 20 and has a rotation axis O2 extending along a width direction of the first supporting arm 20. The rotation axis O2 that the second supporting arm 30 rotates relative to the first supporting arm 20 is perpendicular to the rotation axis O1 that the first supporting arm 20 rotates relative to the lamp body 10 which extends along a height direction of the first supporting arm 20, so that the first supporting arm 20 and the second supporting arm 30 may have at least two free rotation degrees relative to the lamp body 10. Thus, the first supporting arm 20 and the second supporting arm 30 may support the lamp body 10 in multiple directions, and folding of the first supporting arm 20 and the second supporting arm 30 relative to the lamp body 10 may be realized.
The first supporting arm 20 and the second supporting arm 30 are connected by a second rotating seat 50. The second rotating seat 50 includes a first portion 51 and a second portion 52. The first portion 51 is accommodated in and rotatably connected to the first supporting arm 20, and has a rotation axis O2 extending along the width direction of the first supporting arm 20. That is, the rotation axis O2 that the first portion 51 rotates relative to the first supporting arm 20 is perpendicular to the rotation axis O1 that the first supporting arm 20 rotates relative to the lamp body 10. The first supporting arm 20 is provided with a slot 21, and the first portion 51 is received in the slot 21 and rotatably connected to the first supporting arm 20 through a rotating shaft.
In this embodiment, the second rotating seat 50 is disposed at the other end of the first supporting arm 20 without the first rotating seat 40. The second portion 52 may be formed integrally with the first portion 52, and extend outwardly from the first portion 51 along a length direction of the first supporting arm 20. The second supporting arm 30 is rotatably sleeved on the second portion 52, a rotation axis O3 that the second supporting arm 30 rotates relative to second portion 52 is perpendicular to the rotation axis O2 that the first portion 51 rotates relative to the first supporting arm 20.
As shown in
Alternately, the first portion 51 and second portion 52 may be formed separately and then assembled together. The second portion 52 may be rotatably connected to the first portion 51, and the second supporting arm 30 may be fixed to the second portion 52 and rotate along with the second portion 52, also realizing rotation of the second supporting arm 30 relative to the first supporting arm 20.
The rotation axis O3 of the second supporting arm 30 is perpendicular to the rotation axis O2 of the first portion 51, the rotation axis O2 of the first portion 51 is perpendicular to the rotation axis O1 of the first supporting arm 20, and the rotation axis O1 of the first supporting arm 20 is perpendicular to the sidewall of the lamp body 10, thus the second supporting arm 30 and the first supporting arm 20 may form an angle of any degrees therebetween by the rotation of the first supporting arm 20 and the second supporting arm 30, and the photographic lamp 100 supported by the first supporting arms 20 and second supporting arm 30 may be adjusted to any light angle in three-dimensional space, an shown in
During rotation of the second supporting arm 30, the direction of the rotation axis O3 of the second supporting arm 30 may be constantly changing. In
In this embodiment, the rotation axis O2 of the first portion 51 deviates from the center axis of the first portion 51. That is, the first portion 51 is offset connected to the first supporting arm 20, and the second portion 52 may swing relative to the first supporting arm 20 along two directions. In this situation, the first supporting arm 20 and the second supporting arm 30 may be overlapped, and a length of the second supporting arm 30 is preferably less than or equal to the length of the sidewall of the lamp body 10 for better appearance.
During rotation of the first portion 51, the bottom sidewall of the lamp body 10 may collide with the first portion 51, and the lateral sidewall of the lamp body 10 may collide with the second portion 52, which restrict continuous rotation of the first rotating seat 50, and limits a rotation angle of the first rotating seat 50 to be 180°.
The second supporting arm 30 includes a first rod 31 and a second rod 32. The first rod 31 includes a first connecting end and a first free end, and the second rod 32 includes a second connecting end and a second free end. The first and second connecting ends are rotatably connected to the second portion 52 of the second rotating seat 50. That is, first and second connecting ends are hinged together, and the first and second free ends may move towards each other to realize closing of the first rod 31 and second rod 32 of the second supporting arm 30, or move away from each other to realize opening of the first rod 31 and second rod 32 of the second supporting arm 30. The second supporting arm 30 realize supporting to the first supporting arm 20 and the lamp body 10 through opening and closing of the first rod 31 and second rod 32, which further improves a working stability of the lamp body 10.
Both the first rod 31 and the second rod 32 are rotatably sleeved on the second portion 52, and are opened or closed with the second portion 52 as the rotation axis. Specifically, both the first rod 31 and the second rod 32 may rotate relative to the second portion 52 to adjust angles between the first rod 31/second rod 32 and the second portion 52, so that the second supporting arm 30 may be connected to the first supporting arm 20 at multiple angles.
Optionally, opposite sides of the first rod 31 and second rod 32 are provided with a groove 33 and a protrusion 34, respectively. When the first rod 31 and the second rod 32 are closed, the protrusion 34 engages into the groove 33 and positioned within the groove 33 to maintain closing of the the second supporting arm 30. In this embodiment, the protrusion 34 defines a connecting hole 35 therein, the connecting hole 35 is preferably a screw hole. As shown in
For the photographic lamp 100 and the lighting assembly provided in the embodiment of the present application, the first supporting arm 20 is rotatably connected to the sidewall of the lamp body 10 and rotates around a rotation axis perpendicular to the sidewall of the lamp body 10; the second supporting arm 30 is rotatably connected to the first supporting arm 20 and rotates around a rotation axis extending along a width direction of the first supporting arm 20; and the rotation axis of the first supporting arm 20 is perpendicular to the rotation axis of the second supporting arm 30, so that the first supporting arm 20 and the second supporting arm 30 may have at least two free rotation degrees relative to the lamp body 10 and support the lamp body 10 in multiple directions, realizing folding of the first supporting arm 20 and the second supporting arm relative to the lamp body 10. In addition, the second supporting arm 30 includes a first rod 31 and a second rod 32, the first rod 31 and second rod 32 may be opened or closed to realize supporting to the first supporting arm 20 and the lamp body 10, further improving the working stability of the lamp body 10.
