[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An LED photographic lamp with a focusing structure comprises a mounting shell, the mounting shell comprising a shell body with a plurality of air inlets on the outer walls at one end of both sides and a tail cover with an air outlet on one outer wall, a light source mechanism is arranged in the shell body, the light source mechanism comprises four mounting plates fixedly mounted on the inner wall of the shell body, a chip board connected to the outer wall of one side of the four mounting plates by bolts, and an LED lamp welded to the outer wall of one side of the chip board, a focusing mechanism is arranged in the shell body, the focusing mechanism comprises a mounting frame and a focusing lens connected to the inner wall of the shell body by bolts, a protective mechanism is arranged at one end of the shell body, the protective mechanism comprises a protective lens, a heat dissipation mechanism is arranged in the shell body, the heat dissipation mechanism comprises an I-shaped frame connected to the inner walls of both sides of the shell body by bolts, and two groups of heat dissipation fins and a heat dissipation fan fixedly mounted on the top and bottom outer walls of the I-shaped frame.

[0010] Preferably, a limiting block is fixedly provided on the outer wall of one side of the four mounting plates, and the four corners of the chip board are respectively abutted against the inner walls of the four limiting blocks.

[0011] Preferably, a fixing ring is fixed in the installation frame, and the focusing lens is embedded in the fixing ring.

[0012] Through the above solution, the scattered light source emitted by the LED lamp is focused by the focusing lens, so that the scattered light source emitted by the LED lamp becomes concentrated and the light rays are parallel to each other.

[0013] Preferably, one end of the shell is connected to a fixing frame via bolts, and the protective lens is embedded in the fixing frame.

[0014] Through the above scheme, by providing a protective lens that does not cause polarization, the focusing lens is protected to prevent the focusing lens from being contaminated by dust, which may cause the focusing effect of the focusing lens to deteriorate.

[0017] The beneficial effects of the utility model are:

[0018] 1. A focusing mechanism and a protective mechanism are provided. The focusing lens focuses the scattered light source emitted by the LED lamp, so that the scattered light source emitted by the LED lamp becomes concentrated, and the light rays are parallel to each other. The protective lens without polarization protects the focusing lens to prevent the focusing lens from being stained with dust, which causes the focusing effect of the focusing lens to deteriorate. The light source emitted by the LED lamp can be focused to better illuminate a specific position, thereby improving practicality.

[0019] 2. A heat dissipation mechanism is provided. When the blades of the heat dissipation fan rotate, the cold air outside the shell is sucked into the shell and mixed with the heat generated when the LED lamp is working. Then the hot air exchanges heat with the heat dissipation fins. The heat dissipation fan transports the heat at the other end of the heat dissipation fin and part of the hot air to the outside of the shell, which can dissipate the heat of the LED lamp, prevent a large amount of heat from accumulating inside the shell, and improve the heat dissipation effect.

[0020] In summary, the utility model can focus the light source emitted by the LED lamp, better illuminate a specific position, improve practicality, dissipate heat from the LED lamp, prevent a large amount of heat from accumulating inside the shell, and improve the heat dissipation effect.
