The technical features in the invention can be interactively combined to form a new embodiment on the premise of no contradiction and conflict.

As shown in fig. 1 to 6, the flat panel lamp for photography has a split structure, wherein a lamp body 1 and a controller 2 of the flat panel lamp are connected through a cable, the controller 2 supplies power to the lamp body 1 and transmits control signals to control the light efficiency of the lamp body 1. Specifically, the lamp body 1 and the controller 2 are connected by an aviation plug with a wire.

The lamp body 1 comprises a heat dissipation plate 11, wherein the heat dissipation plate 11 is a main structure of the lamp body 1, and a plurality of parallel fins 111 are arranged on the back surface of the heat dissipation plate, so that the heat dissipation effect is achieved, and meanwhile, the heat dissipation plate 11 is reinforced, and the overall structure of the lamp body 1 is further reinforced. The heat dissipation plate 11 is provided with a first frame 14 and a second frame 15 on both sides in the length direction of the fin 111, respectively, to strengthen the structure of the heat dissipation plate 11 in the width direction of the fin 111.

A lamp panel 12 is attached to the front surface of the heat dissipation plate 11, and a plurality of lamp beads are arranged on the lamp panel 12. In the present utility model, the direction of irradiation of the lamp body 1 is the front, and the opposite direction is the rear. In addition, in order to protect the lamp beads on the lamp panel 12, a light-transmitting sheet 13 is additionally arranged in front of the lamp panel 12, and two sides of the light-transmitting sheet 13 are respectively arranged on the first frame 14 and the second frame 15. The light-transmitting sheet 13 may have a soft light-transmitting effect or may have a light-transmitting sheet having only a transparent light-transmitting effect, depending on the specific design.

The lamp body 1 is also provided with an angle adjusting device 3 for adjusting the irradiation direction of the lamp body 1. The angle adjusting device 3 can be used by adopting the common regulator of the existing photographic flat lamp to be matched with the U-shaped frame, and because the U-shaped structure of the U-shaped frame is thick and heavy, the regulators are also required to be arranged at the two sides of the lamp body 1 during use, and the structure of the existing regulator and the U-shaped frame is relatively heavy, so that the angle adjusting device is inconvenient to use and is relatively suitable for the photographic flat lamp with relatively heavy existing weight.

Because lamp body 1 and controller 2 are split type, the structure weight of lamp body 1 has significantly reduced, and current regulator cooperation U type frame's mode is not suitable for this flat lamp very much. For this purpose, a fastening structure is provided on the back of the lamp body 1, and a lockable universal mechanism 31, a fixing plate 32 and a locking mechanism 33 are used to realize detachable and fixed connection with the fastening structure. Specifically, the fastening structure includes at least two hanging holes 114 and one locking hole 115 disposed on the back surface of the heat dissipation plate 11, and the number of the hanging holes 114 is two, three or four, preferably four. The number of the clamping structures can also be set according to the size of the lamp body 1, at least one part can be arranged when the lamp body 1 is large, the lamp body can be conveniently connected at different positions, and the irradiation requirements of different postures are met.

And the fixing plate 32 is provided with hanging columns 321 which are the same in number as the hanging holes 114 and can be correspondingly hung with each hanging hole 114, and the fixing plate 32 is fixed on the back surface of the heat dissipation plate 11 through hanging the hanging columns 321 and the hanging holes 114.

To prevent the hanging post 321 from being released from the hanging post 114, a locking mechanism 33 is provided on the fixing plate 32 to lock with the locking hole 115. The locking mechanism 33 comprises a sleeve 331, a clamping rod 332 and a spring 333, wherein the sleeve 331 is arranged on the back surface of the fixed plate 32, the clamping rod 332 can be connected to the sleeve 331 in a back-and-forth moving fit manner, the front part of the clamping rod 332 can penetrate through the fixed plate 32, the spring 333 is sleeved on the clamping rod 332, the front end and the rear end respectively support against the clamping rod 332 and the sleeve 331, and when the hanging post 321 is hung on the hanging hole 114, the spring 333 pushes the clamping rod 332 to penetrate through the fixed plate 32 and extend into the locking hole 115.

The lockable universal mechanism 31 is in the prior art, such as CN204629000U, and is named as a dual-ball universal adjusting bracket disclosed in the chinese patent document of the dual-ball universal adjusting bracket structure assembly, which can realize a wide-angle adjusting range.

In order to further strengthen the structural strength of the heat dissipation plate 11 and thus the lamp body 1, a third frame 112 and a fourth frame 113 are integrally provided on both sides of the heat dissipation plate 11 in the width direction of the fins 111, respectively, and the widths of the third frame 112 and the fourth frame 113 are larger than the thickness of the heat dissipation plate 11, so that a hollow structure with larger width is formed, and the structural strength of the whole lamp body 1 is strengthened together with the first frame 14 and the second frame 15.

Since the third frame 112 and the fourth frame 113 are provided, the grooves 110 can be formed on both frames for matching and inserting the edges of the light-transmitting sheet 13, so that the light-transmitting sheet 13 can be better fixed.

When in installation, the first frame 14 and the second frame 15 are fixedly connected with each sub-cooling plate, so that dislocation or looseness of the sub-cooling plates in the using process is prevented. As in the embodiment of fig. 5 and 6, the heat dissipation plate 11 is formed by splicing three sub heat dissipation plates.

In addition, the first frame 14 and the second frame 15 are both composed of two sub-frames, and the two sub-frames are covered together by screw connection, and screws penetrate through the heat dissipation plate 11 during connection, and after the connection, the clamping of the side edges of the heat dissipation plate 11 is formed.
