Description

Broadcast Lighting Equipment {Broadcast Lighting Equipment}

The present invention relates to lighting equipment for broadcasting, and more particularly, to a lighting equipment for broadcasting that has a double bumper structure that is strong against external impact and efficiently dissipates heat generated from an internal LED without using a cooling fan. .

In general, as high-power broadcasting lighting, economical light emitting diodes (LEDs) are used because of their high illuminance and long lifespan.

Such broadcast lighting is a high-output device, and when it is used for a long time, high heat is generated such as high heat in a panel or driving circuit on which a light emitting diode (LED) is mounted.

In order to solve this problem, there is a conventional method for cooling using a heat sink having innumerable protrusion-shaped heat dissipation fins. However, such a heat sink is a passive cooling method and has a limitation in cooling ability, making effective and smooth cooling difficult. Therefore, in order to actively dissipate such high heat to the outside, a cooling fan is mounted to perform heat dissipation.

However, although the fan-type heat dissipation device has excellent heat dissipation efficiency, there is a problem in that the cooling fan vibration and noise caused by friction between the cooling fan and air occur when the cooling fan is driven, although it should be quiet due to the characteristics of broadcasting.

In order to solve this problem, a separate vibration-proof structure is additionally installed to reduce vibration noise that may occur at the fixed part of the cooling fan when the cooling fan is rotated, or a vibration-proof rubber pad is applied to reduce vibration noise generated by the cooling fan as much as possible. Efforts are being made to reduce it.

However, in such a cooling fan-type heat dissipation device, there is a limit to reducing the vibration noise of the cooling fan, so it is difficult to apply it to broadcasting lighting equipment that must be operated in a quiet environment without noise, such as during broadcast recording.

In addition, due to the nature of broadcasting, which is frequently manipulated, there are also mistakes such as getting burned by heat or shaking the camera because of surprise during manipulation.

On the other hand, among lighting equipment for broadcasting, lighting equipment that is frequently used outdoors is greatly affected by weather and environment, and especially in areas where it rains frequently, there are many restrictions on the use of lighting equipment outdoors.

To prepare for this, you can use a waterproof cover or an umbrella, but if the waterproof cover melts or water gets in from strong rain and wind, it may cause malfunction.

Therefore, in some cases, broadcasting lighting equipment is waterproofed to prevent water from entering from the outside. There was a need for lighting equipment for broadcasting.

It is characterized in that it has a dual bumper structure formed integrally.

In other words, a long hole is formed between the inner wall 14 and the outer wall 12 constituting the side wall of the body case 10 to have an air layer 16 and thus has a double bumper structure (see FIG. 2A ).

In addition, the main body case 10 forms a support protrusion 18 so as to position the heat sink 20 on the inner side from the bottom of the inner wall 14 to the inside.

Due to the double bumper structure having the air layer 16 between the inner wall 14 and the outer wall 12 formed integrally as described above, the heat generated in the LED PCB 40, etc. inside is less conducted to the outer wall 12. Even if the operator touches the body case 10 with his/her hand, it is possible to prevent the operator from feeling hot.

Meanwhile, in one embodiment, the main body case 10 is illustrated as having a rectangular cylindrical shape through FIGS. 1 to 4 , but the present invention is not limited thereto. Of course you can.

On the other hand, when the main body case 10 is crushed by impact due to the nature of the waterproof structure of the lighting equipment 100 for broadcasting, a gap is created in the waterproof packing and the waterproof function is lost, and an air layer ( 16), so even if the outer wall 12 is crushed, the waterproof packing structure is not crushed because it is a double bumper structure including 16), so it is possible to maintain water resistance and protect the LED PCB 40 and the like inside from external impact.

In addition, in one embodiment, it is preferable that the corner (10a) portion of the body case 10 is thicker than other portions other than the corner so that it is not easily damaged due to an external impact. Preferably, the corner (10a) portion is formed to be at least twice as thick as other portions other than the corner.

In addition, it is preferable that the main body case 10 increases the cross-sectional area of the body case 10 so that the side surface is waved to form a curve so that the heat conduction is good.

For example, the inner surface or outer surface of the inner wall 14 of the main body case 10 may be formed as a wavy curved surface, and, if necessary, the inner or outer surface of the outer wall 12 of the main body case 10 may be wavy and curved. Of course, it can be formed of cotton.

The lower portion of the main body case 10 is coupled to the upper portion of the rectangular frame 62, for example, and is vertically coupled through the coupling holes 11 and 61 at the corners.

A heat sink 20 made of aluminum is positioned and seated in the upper portion of the fulcrum 18 of the body case 10 , that is, inside the body case 10 , and the coupling portion between the body case 10 and the heat sink 20 . There is interposed a packing 68 made of a silicone material for waterproofing.

On the other hand, referring again to FIGS. 1 to 4 , the heat sink 20 has a large heat dissipation area by forming a plurality of heat dissipation fins 22 to protrude upward in one direction of paper or lateral direction while effectively conducting heat in one direction. allow it to pass

In the center of the upper portion of the heat sink 20, the heat dissipation fin 22 does not protrude upward, but a mounting portion 24 is formed, for example, a circular spacer protrusion 26 is mounted, and the spacer protrusion 26 is on the upper portion of the power control case (30) is located.

That is, due to the spacer 26, the power control case 30 is positioned on the upper portion of the heat sink 20 at a certain distance from the heat dissipation fin 20, and through this, even if the temperature of the heat sink 20 rises, direct heat does not reach the power controller. will not

At this time, a packing 69 made of a silicone material for waterproofing is interposed between the spacer protrusion 26 and the power control case 30 .

In addition, the power control case 30 is made of, for example, an aluminum material like the main body case 10, and side walls are formed in all directions from the bottom plate 38 to the outside, and the side walls are the inner wall 32 and the outer wall ( 34) is formed integrally with a double bumper structure, and a long hole is formed between the inner wall 32 and the outer wall 34 to have an air layer 36 (see Fig. 2c).

Preferably, the power control case 30 has the same shape corresponding to the shape of the body case 10 in consideration of coupling with the body case 10 .

In addition, the air layer 36 of the power control case 30 is preferably formed to communicate with the air layer 16 of the body case 10 .

In addition, in a state in which the coupling hole 31 formed in the edge 30a of the power control case 30 and the coupling hole 11 formed in the edge 10a of the main body case 10 coincide with each other, The main body case 10 is coupled to the lower portion of the power control case 20 by means of a coupling member (see FIGS. 3A and 3B).

A power controller (not shown) is mounted on the top of the bottom plate 38 of the power control case 30 , that is, inside the power control case 20 , and a power control made of, for example, aluminum material on the top of the power control case 30 . The cover 80 is coupled.

A packing 70 made of, for example, silicone material is interposed at the coupling portion between the power control case 30 and the power control cover 80 for waterproofing.

A liquid crystal and a switch are provided on the upper surface of the power control cover 80 to operate the lighting equipment 100 for broadcasting, for example, liquid crystal covers 92 and 94 made of transparent polycarbonate (PC) and switch covers made of aluminum. (96) is protected.

Meanwhile, in FIG. 3C , the upper end of the power control case 30 is shown to have the same height as the power control cover 80 , but as another example, the power control case 30 includes one or the entire upper end of the power control case ( 30) It may be formed to extend upwardly so as to protrude higher than the upper surface of the power control cover 80 coupled therein. For example, it may be formed by extending only the corner portion where the coupling hole 31 of the power control case 30 is formed.

According to the above structure, even if the lighting equipment 100 of the present invention falls to the floor due to the user's carelessness or unexpected events, a direct impact is applied to the power control cover 80 including the power controller by the protruding height. This can prevent equipment breakage and internal damage.

On the other hand, even if the main body case 10 and the power control case 30 have a double bumper structure to reduce heat transfer to the sidewall, when the broadcasting lighting equipment 100 is used for a long time, a lot of heat is generated from the LED PCB 40 , etc. Therefore, there are times when it is difficult to directly touch the cases 10 and 30.
