In the lamp 100 having the LED module according to the present embodiment, one surface of the outer cover 160 is open, and the LED module 120 is exposed to the outside through the surface of the open outer cover 160. As the outside air is easily introduced into contact with the LED module 120, the heat dissipation performance is improved. In addition, since the LED module 120 is spaced apart from each other at regular intervals, and the LED module 120 and the outer cover 160 are thermally connected, heat generated from the LED module 120 is coupled to the coupling member 150. And the heat dissipation performance is improved by being conducted to the outer cover 160.

Accordingly, in the lamp 100 having the LED module according to the present embodiment, one surface of the outer cover 160 is opened, and heat is released and heat is generated by convection generated by air easily entering the inner space 162. The LED module 120 and the coupling member 150 and the outer cover 160 uses a heat dissipation mechanism by conduction generated by thermally connected. In addition, the lamp 100 with the LED module according to the present embodiment, since the heat generating the LED module 120 is spaced apart from each other, the LED module 120 to suppress the heat transfer between each other to reduce the heat dissipation area. It is characterized by improved heat dissipation performance by expanding as much as possible.

In addition, the lamp 100 having the LED module according to the present embodiment uses the LED module 120, not a structure in which a plurality of LED units are mounted on one substrate having a large area. Therefore, when a failure occurs, there is no need to replace the entire LED and the board on which the LED is mounted, there is an advantage that the maintenance and repair is convenient because only the failed LED module 120 needs to be replaced.

The outer cover 160 forms an outer body of the lamp 100 and includes an inner space 162 that can accommodate the LED module 120. The outer cover 160 illustrated in FIGS. 1 and 2 has a hemispherical shape and is empty inside, and one surface thereof is open. As illustrated in FIG. 2, the outer cover 160 serves to protect the LED module 120 from rain or snow since the open one surface is positioned toward the ground when the lamp is installed. In addition, outside air may be introduced through an open surface of the outer cover 160 (see FIG. 2).

The LED module 120 and the coupling member 150 are located in the inner space 162 of the outer cover 160. The inner surfaces of the coupling member 150 and the outer cover 160 are connected by the protrusion 152 of the coupling member 150. Therefore, the outer cover 160 is integrally formed with the LED module 120 and the coupling member 150.

The outer cover 160 may be formed of a metal material having excellent thermal conductivity such as copper, aluminum, or steel. The outer cover 160 is thermally connected to the LED module 120 and the coupling member 150. Therefore, heat generated in the LED module 120 may be radiated to the outside by sequentially transferring heat to the coupling unit 150 and the outer cover 160.

The outer cover 160 according to the present embodiment is illustrated as having a hemispherical shape, the outer cover 160 has an inner space 162 to accommodate the LED module 120 and the coupling member 150 therein. Of course, if it can, it can be formed in any shape. For example, the outer cover 160 may have various shapes, such as a rectangular parallelepiped having one surface open, a polyhedron having a trapezoidal side surface, or a semi-cylindrical shape.

Coupling member 150 for coupling the outer cover 160 and the LED module 120 has a side connection portion 154 and the protrusion 152. Side connection portion 154 is a portion coupled to the side of the plurality of LED modules 120, the protrusion 152 is a portion protruding upward from the side connection portion 154. As illustrated in FIGS. 1 to 3, four LED modules 120 are coupled to the side connecting portion 154 at regular intervals in a length direction thereof. And in the side connecting portion 154, the protrusion 152 is formed between the portion where the LED module 120 is coupled.

In the side connecting portion 152, a fastening hole (not shown) corresponding to the side fastening hole 126 formed in the case 122 of the LED module 120 is formed, such that the side connecting portion 152 and the case 122 are formed. Can be screwed together. By such a screw coupling, not only the case 122 of the LED module 120 can be easily separated from the side connection portion 152, but also to be able to adjust the angle of the LED module 120. Therefore, when one of the plurality of LED module 120 has a failure, the administrator can easily remove and replace the LED module 120 has a failure, there is an advantage that easy maintenance and repair. In addition, since the direction in which the light of the LED module 120 is irradiated may be changed according to the position where the lamp 100 is installed, the lamp may be efficiently used.

Of course, the side connecting portion 152 and the case 122 of the LED module 120 are not detachably coupled only by screwing, and the side connecting portion 152 and the case 122 of the LED module 120 are separated from each other. If possible, they can be combined by any configuration. For example, the side connecting portion 152 and the case 122 may be coupled by the protrusion and the insertion groove method into which the protrusion is fitted.

As shown in FIGS. 1 and 2, both ends of the side connecting portion 154 contact the inner surface of the outer cover 160. The protrusion 152 protrudes from the side connecting portion 154 to be in contact with the inner surface of the outer cover 160. The side surface of the side connecting portion 154 may contact the inner surface of the outer cover 160 according to the shape of the inner surface of the outer cover 160. For example, the side connecting portion 154 formed in a straight line may contact the inner surface of the outer cover 160 having a planar shape.

Coupling member 150 is positioned in the LED module 120 spaced apart from each other in the inner space 162 of the outer cover 160. 1 to 3, the four LED modules 120 are located in the inner space 162 at equal intervals from each other. And both sides of the LED module 120 is coupled to the coupling member 150, respectively.

Coupling member 150 may be formed of a metal material, such as the outer cover 160, the metal forming the coupling member 150 may be, for example, aluminum, copper or steel. Of course, the thermal conductivity may be increased by forming the coupling member 150 and the outer cover 160 using the same metal material.

In this embodiment, the four LED modules 120 are coupled by a pair of coupling members 150 having the same shape, but the coupling member according to another embodiment of the present invention is coupled to only one LED module 120. The LED module 120 and the outer cover 160 may be combined. In this case, the coupling member 150 may include only the protrusion 152 coupled to the side surface of the LED module 120 without the side connection part 154 illustrated in FIGS. 1 to 3.

4 is an exploded perspective view of the LED module 120 in the lamp 100 having the LED module 120 according to an embodiment of the present invention, Figure 5 is a cross-sectional view along the line BB 'of FIG.

As illustrated in FIGS. 4 and 5, the LED module 120 located in the inner space 162 of the outer cover 160 includes a case 122 forming an outer body of the LED module 120 and an LED unit. 136, a substrate 132 on which the LED unit 136 is mounted, a module cover 138 that blocks foreign substances such as water and dust into the case 122, and an LED unit 136. It includes a reflecting plate 140 to cause the light generated in the concentrated in a specific direction.

A lot of heat is generated at the position where the LED unit 136 is mounted on the substrate 132. In particular, when the rated current flows normally in the LED unit 136, heat of about 60 ° C. is generated. However, when a large amount of current flows in comparison with the rated current, the temperature is further increased, so that the luminous efficiency of the LED unit 136 is lowered. It may be damaged or broken. As such, in order to emit the high heat generated by the LED module 120 to the outside, the lamp 100 having the LED module 120 according to the present embodiment is the circumference of the case 122 of the LED module 120 It characterized in that the heat radiation fin 124 is formed on. In addition, the case 122 and the substrate 132 of the LED module 120 are all formed of a metal, and the heat radiation fins 124 formed by the high temperature heat generated from the LED unit 136 on the substrate 132 and the case 122. It can be delivered to and released to the outside. In particular, since the one side of the outer cover 160 of the lamp 100 provided with the LED module 120 according to the present embodiment, as shown in Figure 2, the open of the outer cover 160 Outside air introduced through the surface is introduced into the inner space 162 as shown by the arrow, and after heat exchange with the heat radiating fin 124 is discharged to the outside again has a mechanism that the LED module 120 is cooled.

In the LED unit 120 according to the present embodiment, since the substrate 132 is in contact with the case 122, heat generated in the substrate 132 may be easily discharged to the outside through the case 122. .

In addition, in the lamp 100 according to the present embodiment, since the plurality of LED modules 120 are positioned in the interior space 162 spaced apart from each other, heat generated in one LED module 120 is different from other LED modules ( 120 is not substantially delivered. In addition, since the plurality of LED modules 120 are spaced apart from each other, the outside air flows into the space formed between the LED modules 120, so that the heat dissipation of the LED modules 120 can be made more smoothly.

The case 122 has a rectangular parallelepiped shape and one surface thereof is open. Inside the case 122, the LED unit 136, the substrate 132, and the reflector 140 are positioned as shown in FIG. 5. And both side surfaces of the case 122, the side fastening hole 126 is fastened to the bolt (not shown) to be coupled to the coupling member 150 is formed. In addition, the heat dissipation fin 124 is formed in the longitudinal direction on the other surface of the case 122. And the case 122 has an upper fastening hole 128, the screw (not shown) for coupling the case 122 and the module cover 138 may be fastened to the upper fastening hole 128.

The case 122 includes an accommodating part 130 corresponding to an internal space, in which the substrate 132, the LED unit 136, and the reflecting plate 140 are accommodated. Since the case 122 is coupled to the module cover 138 and sealed, foreign matter, such as dust or water, cannot be introduced into the accommodating part 130. And since the LED module 120 itself is sealed and blocked from the foreign matter, the lamp 100 according to the present embodiment can be provided with an outer cover 160 to open one surface to increase the heat dissipation efficiency. will be.

The heat dissipation fins 124 are formed to extend in the longitudinal direction of the case 122, and a plurality of heat dissipation fins 124 are formed at regular intervals along both side surfaces of the case 122. The heat dissipation fin 124 serves to widen the surface area in contact with air so that heat generated from the substrate 132 located inside the case 122 can be easily released to the outside. 4 to 5, the heat dissipation fin 124 has a square shape, but according to another embodiment of the heat dissipation fin may have a variety of shapes, such as semi-circular or triangular.

The LED unit 136 is mounted on one surface of the substrate 132. The substrate 132 is connected to an external power source (not shown). The substrate 132 is positioned in the case 122 by being inserted into the fitting groove 129 formed in the case 122. In addition, as shown in FIG. 5, since the other surface of the substrate 132 is in contact with the case 122, heat generated in the substrate 132 is transferred to the case 122.

10, the substrate 132 may be provided with a temperature sensor 620 that can sense the temperature of the substrate 132. The temperature sensor 620 is attached to one surface of the substrate 132 to determine the temperature of the substrate 132, and provides a detection signal to the control device 640. The controller 640 determines whether the temperature of the substrate 132 is greater than or equal to a predetermined value (for example, 50 ° C.) by the detection signal, and if so, the LED unit 136 to the LED unit 136. The brightness of the LED unit 136 may be reduced or the power may be cut off.

Therefore, in the LED module 120 according to the present embodiment, when the temperature rises above a predetermined value, the brightness of the LED unit 136 is reduced or the power is supplied to the LED unit 136 by the control device 640. In this case, the substrate 132 and the LED unit 136 mounted thereon may be prevented from being damaged due to overheating.

The case 122 and the substrate 132 may also be formed of a metal material such as copper, aluminum, and steel. Since the metal case 122 or the substrate 132 has high thermal conductivity, the heat generated from the LED unit 136 may be efficiently discharged to the outside through the substrate 132 and the case 122.

As shown in FIG. 5, both side surfaces of the substrate 132 are inserted into the fitting groove 129 formed in the longitudinal direction of the case 122. Therefore, the LED module 120 according to the present embodiment has an advantage of easy assembly and disassembly of the case 122 and the substrate 132.

The module cover 138 seals the open surface of the case 122 to block the housing 130 from the outside, and is fastened to the case 122 by screws (not shown). Since the module cover 138 is formed of a material that can transmit light, the light generated by the LED unit 136 is irradiated to the outside after passing through the module cover 138.

The module cover 138 may be formed of a transparent plastic or the like, and may be formed of any material as long as it can transmit light.

A material for reflecting light is formed on the surface of the reflector plate 140. In the reflective plate 140, an insertion hole 142 is formed corresponding to the position and number of the LED units 136. As shown in FIG. 4, the light generated by the LED unit 136 is reflected by the inner surface 144 of the insertion hole 142 so that the light can be irradiated only in a desired direction. Therefore, when the range of light irradiated from the LED unit 136 is to be widened, the angle C on which the inner surface 144 is formed can be reduced, and when the range is narrowed, the angle c can be increased. .

Since the lamp 100 having the LED module 120 according to the present embodiment uses a plurality of LED modules 120 that are detachably coupled to the coupling member 150, one or more of the LED modules 120 may be used. In the event of a failure, it can be easily maintained and repaired by simply removing it from the coupling member 150 and replacing it. In addition, the LED unit 136 is not mounted on the metal substrate of a large area as conventionally by welding, but several to several tens of the LED unit 136 on the substrate 132 having a size corresponding to the case 122. Since the units are mounted, the cost of replacing the substrate is also reduced.

Referring to Figure 6, it can be seen that by adjusting the angle of the LED module 120 is rotatably coupled to the coupling member 150, it is possible to adjust the direction and range of the light irradiation. For example, when the lamp 100 is to irradiate light in a wide range, as shown in FIG. 6, the angle of the LED module 120 may be adjusted.

Since the LED module 120 is coupled to the coupling member 150 by a bolt or the like, it is possible to adjust the angle of the LED module 120 in the process of coupling the LED module 120 to the coupling member 150. .

The LED module 420 illustrated in FIG. 7B has the same configuration as that of the LED module 120 illustrated in FIG. 4, except that cutouts 426 having a predetermined interval in the longitudinal direction of the heat dissipation fin 424 are formed. There is a difference in that it is. The cutout 426 is formed by partially cutting a plurality of heat dissipation fins 424 in a straight line shape, so that air can flow more efficiently between the heat dissipation fins 424. That is, the cutout 426 serves to increase the heat dissipation performance by smoothly flowing air between the heat dissipation fin 424 and the heat dissipation fin 424.
