In general, a floodlight is a lighting device that illuminates a strong light beam from various angles to a building or a person to be clearly visible, and is also called a headlamp, a searchlight, or a lighting lamp.

Such a floodlight projects light by installing a light bulb at the focal point of a parabolic reflector made of metal or glass, and has a very large number of uses, and is used for lighting such as advertising towers, distant buildings, signboards, workshops, and stadiums. .

In addition to incandescent bulbs, mercury lamps, multi-halogen lamps, and the like are among the light bulbs used as light sources of the above-described floodlights.In order to improve the color rendering properties of stadiums such as baseball fields, incandescent bulbs and mercury lamps are sometimes used in combination.

However, in the case of incandescent lamps or mercury lamps, their efficiency is low and they are rarely used as a floodlight recently, and recently, many floodlights using LEDs instead of light bulbs have been released. LEDs are more energy efficient than light bulbs, and have advantages over light bulbs in terms of brightness.

Due to these advantages, a floodlight using an LED is becoming more common instead of a floodlight using a light bulb.

As such, LED (Light Emitting Diode) is compact and has a long lifespan compared to conventional light sources, and because electric energy is directly converted into light energy, it consumes less power and has excellent energy efficiency. Various floodlights are being developed.

The specific configuration of the unit module will be described below.

3 is a front perspective view of the unit module, FIG. 4 is a rear perspective view of the unit module, FIG. 5 is an exploded perspective view of the front of the unit module, FIG. 6 is an exploded perspective view of the rear of the unit module, and FIG. 7 is a state diagram showing the operational relationship of the through pipe provided in the unit module to be.

As shown, the unit module 200 is characterized by having a convective heat dissipation structure, and a housing 210, a lens 220, a through pipe 230, a heat dissipation fin 240, a PCB substrate 250, It contains LED devices.

The housing 210 has a hollow portion formed therein, and the outer surface is manufactured in the shape of a tube having a hexagonal, square, or circular shape, and includes components such as an LED element therein.

Since the housing 210 is formed of a metal material, it has a function of conducting heat and radiating heat generated by the LED element installed inside the housing.

In addition, since the outer surface of the housing 210, which is the outer shape of the unit module, is specified in a hexagonal shape or a square shape, when each unit module is combined, it has a function of maintaining a constant distance between the unit modules.

The PCB board 250 is provided at a central portion of the inside of the housing 210 and divides the inside of the housing 210 into front and rear sides.

The LED element is mounted on the front surface of the PCB substrate 250.

The lens 220 is provided in a shape that covers the LED element, and has a function of imparting straightness to light emitted from the LED element while preventing foreign substances from entering the LED element.

The heat dissipation fin 240 has a structure in which a plurality of thin plates are stacked while having a regular interval, so that air flows between the heat dissipation fins 240 to heat the heat dissipation fins 240 to maximize the effect of heat dissipation.

When the LED element emits light by operating the emitter, heat is generated from the LED element, and the generated heat is conducted to the heat dissipation fin 240, so the temperature of the high temperature part (A) behind the housing 210 divided by the PCB substrate 250 Becomes high, and the air in the high-temperature section (A) is heated.

When the air temperature of the high temperature part A increases, the volume expands and the density decreases, thereby forming an upward airflow.

Since the temperature of the low temperature part (B) in front of the housing 210 divided by the PCB substrate 250 is lower than the temperature of the high temperature part (A), the air in the low temperature part (B) is caused by the chimney effect (stack effect). ) Is sucked through and introduced into the high-temperature portion (A), so that the air from the low-temperature portion (B) having a relatively low temperature quickly flows into the high-temperature portion (A) to heat the heat dissipation fins 240 to improve heat dissipation efficiency.

When the convection speed at which the air from the low temperature portion (B) moves to the high temperature portion (A) is increased, the outside air (C) in a room temperature state is introduced into the low temperature portion (B), so that the function of heat dissipation can be further improved.

That is, when the LED element emits light, the air of the high temperature part (A) is discharged to the outside of the housing 210 while forming a rising airflow, and the air of the low temperature part (B) is sucked into the space through the through pipe 230 to heat exchange. Because the air (C) of room temperature flows into the low-temperature part (B) to increase efficiency, the convection speed at which the outside air (C) flows sequentially to the low-temperature part (B) and the high-temperature part (A) increases, so the unit module The heat dissipation function of 200 is maximized, and as a result, it has a function and effect of increasing the heat dissipation efficiency of the entire transmitter.

Hereinafter, another embodiment of the unit module heat dissipation structure will be described.

Two outer protrusions 211 are provided on each surface of the other side of the housing 210 while the outer protrusions form a constant interval L.

In this embodiment, one of the characteristic configurations is that the distance L between the outer protrusion 211 is formed wider than the distance L between the inner protrusion 212.

By simply combining each of the unit modules of the present embodiment having the above structure up, down, left, and right, there is an effect and effect of easily manufacturing a medium-sized or large-sized light emitter.

In addition, as shown in FIG. 10, it goes without saying that the unit module may have a circular shape and a protrusion may be formed on the outer surface of the unit module.

Looking at the operational relationship of the hexagonal unit module according to this embodiment,

When each unit module 200 is combined, since the interval of the inner protrusion 212 is smaller than the interval of the outer protrusion 211 of the unit module 200, the inner protrusion 212 is formed between the outer protrusions 211 Each unit module 200 can be combined simply by inserting.

Since a certain distance is formed between the unit modules 200 coupled in this way by the inner protrusion 212 and the outer protrusion 211, air can flow between the unit modules 200 and thus the housing 210 from the LED element. ), it can be cooled by dissipating the heat conducted.

That is, when manufacturing a medium-sized or large-sized emitter by connecting the unit modules 200, a passage of air is created while maintaining an appropriate distance between the unit modules 200 by means of inner and outer protrusions so that convection is smoothly performed, It has functions and effects that make it easier to assemble each unit module.
