Description

Technical Field [0001] The present invention relates to an LED lamp assembly having improved heat dissipation structure using rainwater,

The present invention relates to an LED lamp assembly improved in heat dissipation structure using rainwater. More specifically, the present invention relates to an LED lamp assembly in which heat generated from an LED module can be efficiently discharged to the outside by utilizing a housing as a heat sink, The present invention relates to an LED lamp assembly, and more particularly, to an LED lamp assembly having improved heat dissipation structure that can prevent rainwater from flowing into an inner space when raining, thereby preventing dust, insects,

Generally, a streetlight is a lighting facility installed along the edge of a road for safety and security of street traffic. Such a streetlight is installed on a highway, a main road of a city area, a commercial district road, It is provided in a form suitable for it.

Therefore, the conventional street light is composed of a strut which is erected at a predetermined height on the ground surface of the roadside, an arm which is laterally connected to the strut, and a head which is connected to the arm and includes a light source.

When a light source such as a mercury lamp, an incandescent lamp, or a halogen lamp is installed, power consumption is relatively large. In view of this, recently, light emitting diodes (LEDs) having high brightness, reduced power consumption and long lifetime have been used as light sources for street lamps.

On the other hand, since the outdoor lighting device is exposed to the outside, requirements for airtightness, water resistance, dust resistance and heat dissipating are more strict than those of the indoor lighting device. Since LEDs have low heat resistance, generally, a heat dissipating module (heat dissipating member) is used to dissipate heat generated by each LED.

On the other hand, power LEDs with higher luminance than high-brightness LEDs have recently been developed at the same power consumption, and the possibility of replacing high-brightness LEDs is increasing. Power LEDs with power consumption of 2W have a problem in that when the temperature exceeds about 47 ° C, the light output is lowered, the wavelength is changed, and the color is changed. When the heat radiation treatment is insufficient, the LED is damaged within 1 hour .

That is, when the temperature of the power LED is insufficient, the power resistance of the power LED is decreased. As a result, the electric resistance value is decreased. As a result, the amount of current flowing through the power LED is increased and the power consumption is increased.

Korean Patent Registration No. 0808266 discloses a light source including a plurality of power LEDs; A current limiter for limiting the amount of current flowing in the light source portion within a predetermined range; A heat dissipation unit for dissipating heat generated in the light source unit; And a body portion formed integrally with the heat dissipation portion and having the current limiter attached thereto, wherein a ratio of a surface area of the body portion to a power consumption of the light portion is 69 to 125.

Patent No. 0754973 discloses a streetlight in which a light source mounting board on which a light source mounting board on which LEDs are mounted is integrally formed with a four-sided convex body, the remaining four surfaces except the center plane of the convex body are inclined, and the like.

Patent No. 0880200 discloses an LED module having a plurality of light emitting diode (LED) modules mounted on a fixed portion of a heat sink connected to a case of a streetlight in order to extend the irradiation range by varying the irradiation angle of each LED module And a street lamp having a partition for forming a block is posted.

The conventional street light has a structure in which heat is dissipated only by the heat sink formed in the LED module, so that the heat sink formed in the LED module must have a large volume, which is disadvantageous in weight reduction and cost reduction.

In addition, the conventional street lamp is designed such that a heat radiation space and a ventilation hole connected to the outside are secured in the inside of the housing for smooth heat radiation when designing a housing having an external shape. Without these heat sinks and vents, the internal temperature will rise to 80 degrees Celsius by solar heat, so the internal heat sink and vents must be designed.

However, in such a heat dissipation space, various insects such as dust, insects, and the like are accumulated in the inside due to the inflow of insects or dust attracted by the light over time. As described above, the foreign substances accumulated in the internal heat dissipation space obstruct air circulation and reduce the heat dissipation effect.

In addition, since the streetlight has a structure supported by a back louver, it is difficult to maintain the streetlight when an abnormality occurs. Particularly, in order to replace the module when an LED module mounted on the streetlight head malfunctions, it is necessary to separate the streetlight head from the streetlight, so that the workability is relatively lowered and there is a fear of safety accident of the worker.

The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide an air conditioner capable of efficiently discharging heat generated from an LED module to a outside by using a housing as a heat sink, And it is an object of the present invention to provide an LED lamp assembly capable of preventing the accumulation of dust and insects in a space and obtaining a cooling effect of water cooling through cold rainwater flowing into the inside.

It is another object of the present invention to provide an LED lamp assembly which can be easily replaced with a unit LED module only in a state where the unit LED module is coupled to a street lamp.

According to an aspect of the present invention, there is provided an LED lamp assembly having improved heat dissipation structure using rainwater according to the present invention. The LED lamp assembly has a mounting groove formed long in the back and forth direction, A body; A cover coupled to front and rear surfaces of the heat dissipating body; And a plurality of unit LED modules which are coupled to a lower portion of the heat dissipating main body and inserted into the mounting grooves, wherein a plurality of unit LED modules are disposed at regular intervals, wherein the mounting groove is formed at a lower portion of the heat dissipating main body, A side portion formed on both left and right sides of the body portion to form the heat dissipating space portion and having a plurality of flow holes formed in the bottom surface thereof, a dust collecting portion for collecting dust or insects accumulated in the heat dissipating space portion by flowing rainwater into the heat dissipating space portion when raining, And an excellent inflow means for discharging the carcass to the outside through the above-mentioned flow-through hole.

The storm inflow means includes a roof portion formed on the upper portion of the body portion and a rainwater inducing plate formed on the upper portion of the side portion to be positioned below the roof portion and introducing rainwater flowing down the roof portion into the radiating space portion .

The edge guide plate is formed to be bent from the upper portion of the side portion toward the body portion, and is formed to be inclined so as to be gradually lowered toward the body portion.

And an inhibition jaw is formed to protrude upward from the end portion of the abattoir plate to control inflow of rainwater into the heat dissipation space portion.

The air conditioner according to any one of claims 1 to 3, wherein the air conditioner further comprises: a heat dissipation space section A variable drain hole is provided so that it can be introduced.

The roof portion includes a base plate coupled to an upper portion of the body portion, and an inclined wing portion formed to be curved toward both the right and left sides of the base plate toward the excellent guidance plate.

And an overturning means for fixing the heat dissipating main body in a state in which the body portion is connected to the case when the unit LED modules are replaced.

Wherein the turning means includes an insertion passage portion formed to penetrate the upper portion of the body portion in the forward and backward directions and disposed in parallel to the mounting groove and into which a connecting rod extending from the case is inserted, And a fixing member for fixing.

As described above, according to the present invention, heat generated from the LED module can be efficiently discharged to the outside by utilizing the heat radiating body constituting the skeleton of the LED lamp assembly as a heat radiator for discharging heat generated from the LED module to the outside.

Therefore, even if the size and number of the radiating fins formed in the unit LED module are reduced, the heat dissipation effect is not lowered, so that the present invention can contribute to weight reduction and cost reduction of the product. In addition, it is possible to maximize the amount of the heat radiator according to the amount of heat generated by the unit LED module, thereby improving the heat emission characteristic, and thus, it is possible to provide a high reliability for extending the lifetime of the LED.

Further, according to the present invention, it is possible to prevent accumulation of dust, insects, and the like in the internal heat radiation space through which rainwater flows into the inside of the heat dissipation main body during rain, thereby effectively preventing the heat radiation effect from being deteriorated, Cooling effect of water cooling type can be obtained through incoming cold rain water.

In addition, since the heat dissipating body can be fixed upside down while being coupled to the backlight of the streetlight, it is very easy to repair or replace the unit LED module, which simplifies construction and maintenance.

Hereinafter, an LED lamp assembly having improved heat dissipation structure using rainwater will be described in detail with reference to the accompanying drawings.

1 to 4, an LED lamp assembly 1 according to an embodiment of the present invention can be utilized as a headlight of a streetlight. An LED lamp assembly (1) is connected to a light emitting diode (5) of a streetlight to emit light.

The LED lamp assembly 1 according to the present invention includes a heat dissipating body 10, covers 60 and 70 respectively coupled to the front and rear surfaces of the heat dissipating body 10, Modules (80).

The heat dissipation main body 10 is a skeleton of the LED lamp assembly 1 of the present invention and serves as a heat dissipation member for discharging the heat generated from the unit LED module 80 coupled to the bottom. Accordingly, the present invention can utilize the heat dissipation body as a heat dissipation body, thereby improving the emission characteristics of the unit LED module 80, and thus, it is possible to provide a high reliability for extending the lifetime of the LED module.

In the present invention, it is preferable that the heat dissipating body 10 is formed of a metal material having a high thermal conductivity. For example, the heat dissipating body 10 may be formed of aluminum material or aluminum alloy.

Covers (60) and (70) are respectively coupled to the front and rear surfaces of the heat dissipating body (10). That is, the front cover 70 is coupled to the front surface of the heat dissipating main body 10 by screws, and the rear cover 60 is coupled to the rear surface by screws. The rear cover 60 is formed with a circular through-hole 65 into which the connecting rod 7 is inserted. The connecting rod 7 is a mounting end for allowing the LED lamp assembly to be installed at a desired position, and the connecting rod 7 is connected to the back light 5 of the street lamp.

A mounting groove 11 is formed in a lower portion of the heat dissipating body 10. A heat dissipating space portion 13 is formed on the left and right sides of the mounting groove 11 with the mounting groove 11 therebetween. A plurality of unit LED modules 80 are mounted on the mounting groove 11 at regular intervals.

The heat dissipating main body 10 includes a body portion 20 connected to the backlight of the streetlight, side portions 30 provided on both left and right sides of the body portion 20 to form the heat dissipating space portion 13, (13) for introducing rainwater.

The body part 20 comprises a lower body 21 and an upper body 25 formed on the upper part of the lower body 21.

The mounting groove 11 is elongated in the front-rear direction of the lower body 21. An insertion passage portion 15 is formed in the upper body 25 so as to be parallel to the mounting groove 11. The insertion passage portion 15 is elongated in the front-rear direction of the upper body 25.

The side portions 30 are provided on both left and right sides of the body portion 20 to form a heat radiation space portion 13.

The side portion 30 is composed of a bottom plate 31 connected to the lower end of the lower body 21 and a side curved plate 33 bent upward in an end portion of the bottom plate 31. The bottom plate 31 constitutes the bottom surface of the side portion and is provided with a large number of elongated flow holes 32. The outside air can flow to the inside through the flow-through hole 32. In addition, the rainwater flowing into the heat dissipation space portion 13 acts as a discharge port for discharging foreign matter together with the foreign matter.

The side curved plate 33 is bent in the bottom plate 31 and extends upward.

The storm inflow means introduces rainwater into the heat dissipation space portion (13) at the time of rain and discharges the dust or insects accumulated in the heat dissipation space portion (13) through the flow hole (32). In addition, cooling water is cooled by introducing cold rainwater into the inside of the heat dissipation main body.

The storm inflow means includes a roof portion 40 formed on the upper portion of the body portion 20 and a rainwater guide plate 50 formed on the upper portion of the side portion 30.

The roof portion 40 includes a base plate 41 coupled to the upper portion of the upper body 25 and an inclined wing portion 45 formed on the left and right sides of the base plate 41.

The base plate 41 is formed in a rectangular plate shape and installed horizontally. A plurality of screw holes 43 into which the bolts 47 are inserted are formed on the base plate 41 as fixing members of the overturning means to be described later. The threaded hole 43 is formed so as to penetrate to the insertion passage portion 15. The inclined wing portions 45 are formed in a plate shape extending a predetermined length from both the left and right sides of the base plate 41. The inclined wing portion 45 is formed to be curved toward the abdomen guide plate 50 to form an inclined surface.

The outermost induction plate 50 is formed on the side curved plate 33 of the side portion so as to be positioned below the roof portion 40. The storm surge plate 50 serves to introduce rainwater flowing down the inclined wing portion 45 of the roof portion into the heat dissipating space portion 13. Therefore, the edge guide plate 50 is formed to be bent in the direction of the body portion 20 from above the side curved plate 33. So that rainwater can flow into the heat dissipating space portion (13) along the storm relief plate (50). That is, the abutting plate 50 is formed to be inclined so as to gradually decrease in the direction of the body 20. The end portion of the excellent guiding plate 50 is spaced apart from the upper body 25 by a predetermined distance so that the rainwater can enter the heat dissipating space portion 13.

Meanwhile, as shown in Figs. 5 and 6, a restraining jaw 55 may be formed at the end of the abdomen induction plate 50. As shown in Fig. The restricting jaw 55 is formed so as to protrude upward from the end of the abutting guide plate 50. This is for controlling the inflow of rainwater into the heat dissipation space portion 13. [ That is, when the amount of the rainwater flowing along the rainwater guide plate 50 is small, the rainwater can not pass the rainwater restrainer 55, and rainwater is prevented from flowing into the heat dissipation space portion 13. At this time, the rainwater blocked by the restricting jaw 55 from flowing into the heat dissipating space portion 13 is discharged to the outside of the heat dissipating body through the variable drain hole 72. The variable drain hole 72 may be formed in the front cover 70 or the rear cover 60, respectively, or may be formed in both the front and rear covers. The variable drain hole 72 is formed at a position corresponding to the restricting jaw 55 in a state where the front cover 70 and the rear cover 60 are coupled to the heat-radiating body. The variable drain hole 72 can be entirely or partially clogged with the sealing silicon, and the size can be adjusted. When the variable drain hole 72 is closed, the rainwater can not be discharged to the outside through the variable drain hole 72. Therefore, when rainwater continues to collect on the rainwater guide plate 50 and the water level exceeds the height of the rainwater restricting channel 55, And flows into the heat dissipating space portion. As described above, the variable drain hole can be left open or blocked with silicone to control the inflow of rainwater according to the location, the location and the climatic conditions of the streetlight.

Referring again to FIGS. 1 to 4, the unit LED module 80 is coupled to the lower portion of the body portion 20 and inserted into the mounting hole 11. One or two or more unit LED modules 80 are installed. A gap maintaining plate 90 is provided between the unit LED modules 80 to maintain a gap therebetween. The gap retaining plate 90 is coupled to the lower portion of the body portion 20 by a screw.

Each unit LED module 80 includes a base plate 81, radiating fins 85 formed vertically to the top of the base plate 81, and a substrate 87 provided below the base plate 81.

Fixed portions 83 for fixing the lower body 21 are formed on both sides of the base plate 81, respectively. A through hole is formed in the fixing portion, and a fixing screw 84 is inserted into the through hole to be coupled to the lower body 21.

On the bottom surface of the base plate 81, a substrate 87 on which a light emitting diode 89 for illumination is mounted is provided. The substrate 87 is preferably a metal PCB formed of a metal material to facilitate heat transfer.

The plurality of radiating fins 85 are formed at regular intervals. The upper part of the radiating fins 85 is in contact with the lower part of the upper body 25.

The present invention can utilize the heat dissipating body 10 as a heat dissipation body by the structure of transferring the heat generated in the unit LED module 80 to the body portion 20 so that the heat generated in the unit LED module 80 can be efficiently Lt; / RTI >

1, the present invention is installed to be coupled to a connecting rod 7 connected to a street lamp 5. Therefore, when the unit LED module 80 is to be replaced for repairing the unit LED module 80, the operator must unscrew the fixing screw 84 from the lower portion of the heat radiation body 10 and remove the unit LED module 80 Work is inconvenient and there is a risk of safety accident. Therefore, the present invention includes a rollover unit that can fix the heat-radiating body 10 when the unit LED module is replaced so that the unit LED module 80 can be easily replaced.

The overturning means can fix the heat dissipating main body 10 upside down while the body portion 20 is connected to the connecting rod 7 of the back side.

The rollover means includes an insertion passage portion 15 formed on the upper portion of the body portion 20 and an insertion rod 7 inserted into the insertion passage portion 15 and a fixing member for fixing the body portion 20 .

The insertion passage portion 15 is formed in the upper body 25 of the body portion. The insertion passage portion 15 is formed so as to pass through the upper body 25 in the longitudinal direction. Therefore, the insertion passage portion 15 is formed to be long in the front-rear direction, and is positioned in parallel with the mounting groove 11. [ The circular insertion passage portion 15 is formed to be larger than the diameter of the connecting rod 7.

The connecting rod 7 of the lid is inserted into the insertion passage portion 15 through the through hole 65 of the rear cover 60. The fixing member serves to fix the body portion 20 to the connecting rod 7 inserted into the insertion passage portion 15. [ As one example of the fixing member, a fixing bolt 47 inserted and fastened to the screw hole 43 can be used. When the fixing bolt 47 is tightened, the end of the fixing bolt 47 can press the outer circumferential surface of the connecting rod 7 to fix the heat dissipating body 10 to the connecting rod 7. When the fixing bolt (47) is loosened, the heat dissipating body (10) can be rotated in a state where the connecting rod (7) is inserted into the insertion passage part (15). Therefore, when replacing the unit LED module 80, the fixing bolt 47 is loosened to rotate the heat radiation body 10 by 180 degrees, and the upper and lower parts are turned upside down, and then the fixing bolt 47 is tightened. In this case, since the unit LED module 80 coupled to the lower part of the heat dissipating body 10 is directed toward the sky, the operator can perform the replacement operation of the unit LED module 80 from above the heat dissipating body 10, Can be greatly facilitated.

Meanwhile, an LED lamp assembly according to another embodiment of the present invention further includes an escape prevention unit. The separation preventing unit serves to support the unit LED module from below. The release preventing unit is provided to prevent the unit LED module from falling downward from the heat dissipating main body by releasing the fixing screw for fixing the unit LED module to the heat dissipating main body.

7 and 8, the detachment prevention unit includes a pressing unit that is provided on the bottom surface of the heat dissipating body to press the unit LED module 80 upward, and a pressing unit that presses the unit LED module 80 in a state of pressing the unit LED module 80 And a fastener (130) for fixing the pressing means to the heat dissipating body (10).

The pressing means has a hinge portion (101) and a holder (110) rotatably coupled to the hinge portion (101).

The hinge portions (101) are formed on the bottom surface of the heat dissipating main body (10) so as to be positioned on both left and right sides of the mounting grooves. The hinge portion 101 is formed long in the front and rear of the lower body 21. The hinge portion 101 has a C-shape with one side opened and a coupling hole formed inside.

One end of the holder 110 is inserted into the coupling hole of the hinge portion 101 and is rotatably coupled to the hinge portion 101. Therefore, the holder 110 is rotatable up and down in a state of being coupled to the hinge portion 101. When the holder 110 is rotated in the upward direction and fixed to the lower part of the unit LED module 80, the holder 110 supports the unit LED module 80 from below. When the unit LED module 80 is to be replaced, the holder 110 is rotated downward to be separated from the LED module 80.

The holder 110 includes a rotation shaft 111 inserted into a coupling hole formed in the hinge portion 101 and a pressing plate 115 extending from the rotation shaft 111.

The rotary shaft 111 is formed in a bar shape. The pressing plate 115 is formed in a plate shape extending from the rotating shaft 111. The pressing plate 115 can rotate around the rotating shaft 111 in a state where the rotating shaft 111 is inserted into the hinge unit 101 and is engaged. When the holder 110 is fixed by the fixture 130 after the pressing plate 115 is rotated in close contact with the lower part of the unit LED module 80, the pressing plate 115 supports the unit LED module 80 from below It is possible to prevent the unit LED module 80 from deviating even if the fixing screw 84 is loosened. When the fixed state by the fixing member 130 is released, the pressing plate 115 loses its supporting force with respect to the unit LED module 80.

The fixture 130 is coupled to the rotation shaft 111 to block the rotation of the rotation shaft 111.

The fixture 130 has an insertion part 131 inserted into the fixing hole 112 formed in the rotary shaft 111 and a fixing part 130 fixed to the insertion part 131 so that one side is in contact with the hinge part 101, And a contact portion 135 contacting the contact portion 115.

The fixing hole 112 includes a center portion 113 formed in a circular shape at the center of the rotating shaft 111 and an opening portion 114 having a width smaller than the diameter of the center portion 113.

The insertion section 131 includes a first section 132 having a shape corresponding to the shape of the center section 113 and a second section 132 having a shape extending from the first section 132 and corresponding to the shape of the opening section 114. [ (133).

The insertion portion 131 is inserted into the fixing hole 112 from one side of the rotating shaft 111. The contact portion 135 is formed in a curved shape at the end of the insertion portion 131. One side of the contact portion 135 is in contact with the hinge portion 101 in a state where the insertion portion 131 is inserted into the fixing hole 112. Since the other side is in contact with the pressing plate 115, the pressing plate 115 is prevented from rotating downward. When the insertion portion 131 is removed from the rotary shaft 111, the pressing plate 115 rotates downward by its own weight.

Even if the fixing screw for fixing the unit LED module to the heat dissipating body is loosened by the separation preventing unit as described above, the unit LED module can maintain the state of being coupled to the heat dissipating body. When the unit LED module is replaced, the unit LED module can be separated from the heat dissipation body by removing the fixture from the rotation shaft and releasing the fixing state.
