From the above description, the beneficial effects of the present invention are: according to the high-power handheld photographic lamp provided by the invention, one space is divided into two mutually parallel spaces through the PCB and the fan to form the channel, when the LED lamp panel works, heat is transferred to the plurality of heat dissipation plates, the heat enters the air outlet channel through the heat dissipation plates due to the fact that the air outlet channel is surrounded by the heat dissipation plates, the fan sucks cold air from the air inlet channel, the cold air is blown into the air outlet channel through the fan, when the cold air passes through the air outlet channel, the heat generated by the LED lamp panel and dissipated into the air outlet channel can be taken away quickly, meanwhile, the PCB avoids the problem that the heat of the air outlet channel enters the air inlet channel and is mixed with cold air and hot air, the hot air can be smoothly and quickly discharged from the air outlet channel, a good heat dissipation effect is kept, and further the fact that LEDs with more LED lamp beads are arranged on the small-size handheld photographic lamp can be guaranteed, and the high-power illumination effect is achieved.

Furthermore, a plurality of fins are arranged in the air outlet channel, and the fins are perpendicular to the PCB.

Furthermore, the fins are wave-shaped fins and are arranged at equal intervals.

From the above description, the arrangement of the fins can play the effects of wind guiding, heat conduction and heat dissipation, and can also play a supporting role to ensure that the PCB is horizontally arranged.

Furthermore, a spacer is arranged between the air outlet channel and the air inlet channel.

According to the above description, the heat of the air outlet channel is prevented from entering the air inlet channel and mixing the cold air and the hot air by arranging the isolating sheet to be matched with the PCBs of different models for use.

Further, the fins and the spacers are perpendicular to each other; the height of the fin on one side of the spacer is smaller than that of the fin not on one side of the spacer.

As can be seen from the above description, the height difference formed by the fins with different heights is used for arranging the spacers, and can also provide more space for other components such as batteries and the like.

Furthermore, the high-power handheld photographic lamp comprises a first heat dissipation plate, a second heat dissipation plate and a third heat dissipation plate, wherein the first heat dissipation plate, the second heat dissipation plate and the third heat dissipation plate form a cuboid space, and the first heat dissipation plate and the third heat dissipation plate are arranged in parallel and are vertically connected with the second heat dissipation plate.

Furthermore, a top plate is arranged above the air inlet channel, and a knob, a display screen and air holes are arranged on the top plate.

As can be seen from the above description, the air holes are only communicated with the air inlet channel, and can also play a certain air inlet effect. The knob and the display screen are electrically connected with the PCB and used for controlling and displaying technical parameters such as brightness, color temperature and the like of the LED lamp panel.

Furthermore, both ends of the second heat dissipation plate are respectively provided with a side baffle, the side baffle is provided with an air inlet and an air outlet, the side baffle protrudes out of the top plate, and the height of the side baffle protruding out of the top plate is larger than that of the knob.

From the above description, the height that the side baffle protrudes from the top plate is greater than the height of the knob, so that the side baffle can play a supporting role when the knob is placed downwards, the knob is prevented from contacting a desktop or the ground, and the knob is effectively protected.

Furthermore, one side of the LED lamp panel, which is far away from the air outlet channel, is provided with a light softening plate.
