Description

[0001] The present invention relates to an LED lamp assembly for preventing separation of an LED module,

The present invention relates to an LED lamp assembly for preventing the LED module from escaping, and more particularly, to an LED lamp assembly capable of effectively preventing a screw for fixing the LED module from being released and allowing the LED module to fall off.

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. 10-1505830 discloses an LED lamp assembly.

The LED lamp assembly has a structure in which the LED module is mounted on a lower portion of the housing and is directly exposed to the outside in order to enhance the heat radiating effect. In this case, the LED module is fixed to the housing by the screw of the housing, and when the screw fixing the LED module is released, the LED module may be detached and drop downward.

Hereinafter, an LED lamp assembly for preventing detachment of the LED module 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.

An LED lamp assembly (1) of the present invention comprises a main body, an LED module (80), a screw member (84), and an escape prevention unit.

The main body is a skeleton of the LED lamp assembly 1, and a mounting groove 11 to which the LED module 80 is coupled is formed below the main body. The LED module (80) mounted on the main body has a structure in which the lower portion is exposed to the outside.

It is needless to say that various types of bodies other than the illustrated ones can be used as long as the bottom of the LED module 80 is exposed to the outside.

The main body includes a housing 10, covers 60 and 70 coupled to the front and rear surfaces of the housing 10, LED modules 80 coupled to the bottom of the housing 10, , And storm inflow means.

The housing 10 serves as a heat radiator that discharges heat generated from the LED module 80 coupled to the lower portion to the outside. Accordingly, the present invention can utilize the housing 10 as a heat discharging body, thereby improving the discharge characteristic of the LED module 80, thereby providing a high reliability in extending the lifetime of the LED module.

In the present invention, the housing 10 is preferably formed of a metal material having a high thermal conductivity. For example, the housing 10 may be formed of aluminum material or aluminum alloy.

Covers 60 and 70 are coupled to the front and rear surfaces of the housing 10, respectively. That is, the front cover 70 is coupled to the front surface of the housing 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 the lower portion of the housing 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. In the mounting groove 11, a plurality of LED modules 80 are mounted at regular intervals.

The housing 10 includes a body portion 20 connected to the backlight 5 of the streetlight, a side portion 30 provided on both the left and right sides of the body portion 20 to form the heat radiation space portion 13, And an inflow introduction means for introducing the rainwater into the space portion (13).

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 forms a bottom surface of the side portion 30 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).

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.

And an inhibition jaw 55 may be formed at the end of the abdomen induction plate 50. [ 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 which has been blocked from flowing into the heat dissipating space portion 13 by the restricting jaws 55 is discharged to the outside of the main 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 main 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.

The 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 LED modules 80 are installed. A spacing plate 90 is provided between the 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 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 screw member (84) is inserted into the through hole to be coupled to the lower body (21). The screw member is screwed to the lower body to fix the LED module to the main body.

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 housing 10 as a heat discharger by transferring the heat generated from the LED module 80 to the body section 20 and thus efficiently dissipate the heat generated from the LED module 80 to the outside .

1, the present invention is installed to be coupled to a connecting rod 7 connected to a street lamp 5. Therefore, when replacing the LED module 80 for repairing the LED module 80, the operator must unfasten the fixing screw 84 from the lower portion of the housing 10 and remove the LED module 80, There is a concern about safety accidents. Therefore, the present invention is equipped with a rollover means capable of fixing the main body upside down when replacing the LED module so that the replacement of the LED module 80 can be made very easy.

The overturning means can turn the housing 10 upside down while the body portion 20 is connected to the connecting rod 7 of the backrest.

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 peripheral surface of the connecting rod 7 to fix the housing 10 to the connecting rod 7. When the fixing bolt (47) is loosened, the housing (10) can be rotated in a state where the connecting rod (7) is inserted into the insertion passage part (15). Therefore, when replacing the LED module 80, the fixing bolt 47 is loosened and the housing 10 is rotated 180 degrees so that the upper and lower parts of the main body are turned upside down and then the fixing bolt 47 is tightened. In this case, since the LED module 80 coupled to the lower portion of the housing 10 is directed toward the sky, the operator can easily replace the LED module 80 in the inverted housing, thereby facilitating the replacement operation.

The detachment prevention unit is for blocking the falling of the LED module 80 mounted on the lower part of the main body by dropping the screw member 84 for fixing the LED module 80 downward.

The escape prevention unit shown in the figure is provided on the bottom surface of the housing 10 and includes a pressing means for pressing the LED module 80 upward and a pressing means for pressing the pressing means in the housing 10 so that the pressing means can be held in a state of pressing the LED module 80. [ (130) fixed to the base (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 housing 10 so as to be positioned on both left and right sides of the mounting groove 11. [ 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 in a state of being closely attached to the lower portion of the LED module 80, the holder 110 supports the LED module 80 from below. When replacing the LED module 80, the holder 110 is rotated downward to separate the LED module 80 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 so as to closely contact the lower portion of the LED module 80, the pressing plate 115 supports the LED module 80 from below, It is possible to prevent the LED module 80 from deviating even if the LED module 84 is released. When the fixed state by the fixture 130 is released, the pressing plate 115 loses its supporting force with respect to the 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 coupled to the insertion part 131 so that one side is in contact with the hinge part 101, (Not shown).

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.

In this way, the fixture 130 can be coupled to the holder 110 to fix the LED module 80. In order to replace the LED module 80, the fixture 130 is removed from the holder 110. The front cover 70 and the rear cover 60 may have a moving hole (not shown) through which the fastener 130 can be moved to separate the fastener 130 from the holder 110 in a state where the front and rear covers are coupled to the housing 10 73 are formed. Therefore, after the fixture 130 coupled to the holder 110 is pushed in the direction of the moving hole 73, the pressing plate 115 of the holder 110 is rotated downward so that the holder 110 with respect to the LED module 80 The fixing can be released. After the replacement of the LED module 80, the pressing plate 115 is rotated upward, and then the fixture 130 is pushed through the movement hole 73 to be coupled to the holder 110, thereby fixing the holder.

Another example of the fastener is shown in Fig.

Referring to FIG. 5, the fastener may include an engaging screw 150 that passes through the rotating shaft 111 and is fixed to the housing. When the pressing plate 115 of the pressing means is rotated so as to closely contact the lower portion of the LED module 80 and the rotating shaft 111 is fixed by the engaging screw 150, the pressing plate 115 presses the LED module 80 It is possible to prevent the LED module 80 from being detached even if the fixing screw 84 is loosened

As described above, even when the fixing screw for fixing the LED module to the main body is released by the detachment prevention unit, the LED module can be maintained in the state of being coupled to the main body. When the LED module is replaced, the LED module can be removed from the main body by removing the fixture from the rotating shaft to release the fixing state and releasing the fixing screw.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention. . Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
