Description

Technical Field

[0001] The utility model relates to the technical field of fill-in lights, in particular to a heat-dissipating live broadcast fill-in lighting fixture. Background Art

[0002] With the popularization of the Internet, live streaming has gradually become a mainstream marketing method. Anchors will broadcast live indoors or even outdoors according to customer needs. In order to achieve better live broadcast pictures, anchors usually use fill lights to improve picture quality.

[0003] When the fill light is used for a long time, the electronic components inside the fill light will usually heat up, resulting in a certain amount of heat retained in the fill light. When used for a long time, the fill light is easily damaged. With the continuous development of technology, some fill lights are also equipped with cooling fans. The internal cooling fans usually exhaust or inlet air along the width of the lamp tube. Since the internal space of the lamp tube is relatively small, the exhaust end and the air inlet end of the cooling fan are relatively close to the inner wall of the lamp tube. The inner wall of the lamp tube will block the inlet or exhaust port of the cooling fan, resulting in poor air intake and exhaust effects of the cooling fan, thereby affecting the cooling effect.

[0004] Therefore, we propose a heat dissipation type live broadcast fill light lighting fixture to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problem of poor heat dissipation effect.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a heat-dissipating live broadcast fill-light lighting fixture, comprising a cylinder with openings at both ends, a rear cover detachably installed at the rear end of the cylinder, a mounting sleeve installed at the front end of the cylinder, an LED light source installed inside the mounting sleeve, a heat-dissipating fan for exhausting air in the direction of the LED light source installed inside the cylinder, a heat-dissipating fin installed at the outlet end of the heat-dissipating fan, and the heat-dissipating fin located between the LED light source and the heat-dissipating fan.

[0007] Furthermore: a plurality of fixing rods are fixed at equal intervals on the circumferential surface of the LED light source, and one end of the plurality of fixing rods away from the LED light source is fixedly connected to the inner wall of the mounting sleeve, and a certain gap is left between adjacent fixing rods.

[0008] Further: the heat dissipation fan includes a heat dissipation shell and a mounting frame installed in the heat dissipation shell, a motor is installed on one side of the mounting frame, one end of the motor passes through the mounting frame and is fixed with a rotating seat, and a plurality of fan blades are equidistantly fixed on the circumferential surface of the rotating seat.

[0009] Furthermore: protective covers are installed at both ends of the heat dissipation shell, and the motor and a plurality of fan blades are located between the two protective covers.

[0010] Furthermore: a mounting seat is fixed to the inner wall of the cylinder, a plurality of mounting holes are opened on the heat sink, and bolts are installed inside the mounting holes, and the bolts penetrate the heat dissipation shell and are threadedly connected to the mounting seat.

[0011] Furthermore: a plurality of air inlet holes are provided on the cylinder, and a plurality of the air inlet holes are located at the air inlet end of the heat dissipation fan.

[0012] Beneficial effects of the utility model:

[0013] The utility model is provided with a heat dissipation fan inside the cylinder. When the motor in the heat dissipation fan rotates at a high speed, it can drive a plurality of fan blades to rotate, so that the heat in the cylinder can be discharged through the fan blades, thereby playing a role in heat dissipation, reducing the damage caused by excessive temperature in the fill light, thereby improving the stability of the fill light.

[0014] Since the exhaust end of the heat dissipation fan is arranged along the length direction of the cylinder, air enters the rear side of the cylinder and is exhausted from the position of the LED light source, reducing the obstruction of the air inlet or outlet of the heat dissipation fan, so that the heat dissipation fan has good air intake and outlet effects, thereby improving the heat dissipation effect of the fill light.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0022] Embodiments of the present utility model:

[0023] A heat dissipation type live broadcast fill-in lighting fixture comprises a barrel 1 with openings at both ends, a rear cover 2 is installed at the opening at the rear end of the barrel 1 by bolts, and a handle 11 is fixed on the rear cover 2, and the arrangement of the handle 11 facilitates the carrying of the barrel 1; a mounting sleeve 3 is installed at the opening at the front end of the barrel 1 by bolts, and an LED light source 4 is arranged in the mounting sleeve 3, and the LED light source 4 and the mounting sleeve 3 are arranged coaxially, a mounting seat 12 is fixed to the bottom of the barrel 1, and the mounting seat 12 is installed on a tripod bracket (the tripod bracket belongs to the prior art and is not described in detail in this application).

[0024] The outer surface of the LED light source 4 is fixed with multiple fixing rods 7 at equal intervals in the circumferential direction, and the ends of the multiple fixing rods 7 away from the LED light source 4 are fixed to the inner wall of the mounting sleeve 3. It should be noted that a certain gap is left between adjacent fixing rods 7 so that the heat in the cylinder 1 can be automatically discharged. A plurality of groups of air inlet holes 10 are arranged at a position of the cylinder 1 away from the LED light source 4. Through the gaps between adjacent fixing rods 7 and the arrangement of the air inlet holes 10, the heat in the cylinder 1 can be automatically discharged, thereby achieving a preliminary heat dissipation effect.

[0025] A mounting base 8 is fixed to the inner wall of the cylinder 1, and a plurality of through holes are opened on the mounting base 8, each of which is provided with a bolt, and a plurality of bolts are threadedly connected through the through holes on the mounting base 8 and the mounting holes on the heat sink 51 and the heat sink 6, thereby playing the role of installing the heat sink 51 and the heat sink 6. By setting the heat sink 6, the heat dissipation effect can be improved.

[0026] Specifically, the heat dissipation fan 5 includes a heat dissipation shell 51, a mounting frame 52 is fixed inside the heat dissipation fan 5, and a motor 53 is fixed on one side of the mounting frame 52, and the output end of the motor 53 passes through the mounting frame 52 and is fixed with a rotating seat 54, and the outer surface of the rotating seat 54 is fixed with a plurality of fan blades 55 at equal intervals along the circumferential direction. Through the setting of the heat dissipation fan 5, heat dissipation can be performed in the cylinder 1, and protective covers 56 are fixed at both ends of the heat dissipation shell 51, and the motor 53 and the plurality of fan blades 55 are located between the two protective covers 56. Through the setting of the protective cover 56, a protective effect is played to reduce the possibility that the power cord in the cylinder 1 enters the heat dissipation shell 51 and is damaged.

[0027] When the fill light is in use, the motor 53 and the heat sink 6 can be turned on. The output end of the motor 53 drives a plurality of fan blades 55 to rotate at high speed through the rotating seat 54, so that the outside air can enter the cylinder 1 through the air inlet 10, so that the wind exhausted from the cylinder 1 enters the heat sink 6. The exhausted wind can be cooled by the heat sink 6, and the wind force after cooling is discharged again from the gap between adjacent fixing rods 7, thereby accelerating the air flow speed in the cylinder 1, so that the fill light has a good heat dissipation effect, and the stability of the fill light is guaranteed.
