Description

LED Luminaire for Light Pole {LED Luminaire for light pole}

The present invention relates to LED lamps for light poles which are installed and supported on pillars using LED lamps such as LED street lamps, LED security lamps, etc. In particular, a plurality of LED lamp units can be pivotally connected to each other with one hinge axis, and at the same time the base is covered. It relates to a LED lighting fixture for coupling to at the same time.

LED lamps for a column including a conventional pillar (3) and the arm (1) installed on the pillar (3) is a heat dissipation main body supported on the arm and the LED module installed in the heat dissipation main body and The cover is installed on the heat dissipating body to protect the LED module.

The heat dissipation main body is composed of a heat sink composed of a base on which the LED module is installed and a plurality of cooling fins formed perpendicular to the upper surface of the base.

In addition, the heat dissipation main body is further configured to be mounted on the arm bracket mounting bracket.

The arm bracket can be installed integrally or separately on the heat dissipation body.

The LED module consists of a metal PCB installed on the lower surface of the base and a plurality of LEDs mounted on the metal PCB.

The cover is screwed into the base and fixed.

When a plurality of such conventional LED luminaires are implemented, each of the conventional LED luminaires is pivotably installed on both sides of the arm mounting bracket.

Therefore, the cover is screwed and fixed to the base, and each of the LED luminaires are installed by a hinge shaft and a hinge member on a separate arm mounting bracket, so the number of parts increases, the assembly work is long.

In addition, since the LED luminaires are rotatably installed on both sides of the arm mounting bracket, the LED luminaires cannot be installed on the structural side.

In addition, since the hinge shaft is installed in the LED luminaire and the bracket for mounting the arm, when too many angles are bent, the space between the LED luminaire and the LED luminaire becomes too wide, resulting in an unbalanced illuminance.

In addition, since the cooling fins are exposed to the outside, when the impact is applied to the outside, the cooling fins are damaged and the heat dissipation performance is reduced, which may significantly shorten the life of the LED luminaire.

Such a conventional heat dissipation body is molded by die casting with aluminum.

However, aluminum die-casting products are heavier than magnesium die-casting products and therefore heavier in weight for the same volume.

Since aluminum products are heavier than magnesium products, when at least two or more LED luminaires are installed on one arm, there is a high risk that the arm is bent or broken due to a large load on the arm.

To eliminate this risk, one LED luminaire should be installed on one arm, which increases the number of arm rods, which is uneconomical in terms of construction or cost.

On the other hand, the thickness of the aluminum die casting cooling fin is formed thicker than the thickness of the magnesium die casting cooling fin, because the relatively low solidification rate, the grain is not relatively fine.

For this reason, aluminum cooling fins have a thicker thickness than magnesium cooling fins for the same volume, so the number of installations is smaller, resulting in a much smaller contact area with the atmosphere, resulting in poor heat dissipation performance.

The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a LED luminaire for a column that can be rotated at a desired angle while significantly reducing the assembly process by assembling a plurality of parts with one hinge axis.

In order to achieve the above object, the LED lamp for lamps described in claim 1 of the present invention,

The hinge member includes a first hinge installed in the first LED luminaire, a second hinge installed in the second LED luminaire, and a hinge shaft connecting the first hinge and the second hinge.

According to the configuration of claim 1, since the first LED and the second LED luminaires are connected by a hinge member, the structure can be increased by two or more sideways, and even if the turning angle is increased, the middle does not open and maintains the uniformity of the road surface. You can.

The LED luminaire for a lamp column of Claim 2 of this invention,

The first hinge includes a first base hinge formed on the side of the first base, a first cover hinge formed on the side of the first cover,

The second hinge includes a second base hinge formed on the side of the second base and a second cover hinge formed on the side of the second cover,

The hinge shaft is connected to the first base hinge, the first cover hinge, the second base hinge, and the second cover hinge.

According to the structure of Claim 2, it can turn while supporting a cover to a base by one hinge shaft, and it can remarkably reduce the number of parts, and can significantly reduce an assembly work time.

The LED luminaire for the lamp column of Claim 3 of this invention,

A third LED luminaire further disposed on the other side of the second LED luminaire, an additional hinge member for pivotally connecting the third LED luminaire and the second LED luminaire, and a pivot angle of the additional hinge member Further comprising a pivot angle determining member,

According to the configuration of claim 3, one arm mounting bracket can support a plurality of LED luminaires, and the side wall serves to support the arm mounting bracket while protecting the plurality of cooling fins.

As is apparent from the above description, the present embodiment has the following effects.

Since the first LED luminaire and the second LED luminaire are connected by a hinge member, two or more of them can be extended laterally in structure, and even when the turning angle is increased, the middle does not open even when the turning angle is increased, so that the roughness of the road surface can be maintained uniformly.

In addition, the LED luminaires can be pivoted with respect to each other while supporting the cover to the base with one hinge shaft, thereby significantly reducing the assembly work time by significantly reducing the number of assembly and turning parts.

In addition, since the LED luminaires and the LED luminaires are connected by hinged shafts, if the central LED luminaire is supported by one arm mounting bracket, the other LED luminaires next to it can be supported by the hinge axis and the pivot member, It acts as a protective plate to protect the cooling fins and prevents the cooling fins from being damaged by external shocks while supporting the brackets.

In addition, it is very convenient to assemble the sliding inclined fitting groove on the inclined side wall and simultaneously support it without additional fixing parts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, where like reference numerals refer to like parts, and detailed description thereof will be omitted.

1 is a perspective view showing a separate LED luminaire for the lamp according to a preferred embodiment of the present invention, Figure 2 is a perspective view of the combination of Figure 1, Figure 3 is a combined state of the first LED and the second LED luminaire and swinging 4 is a front view illustrating a state in which three LED lamps are installed, and FIG. 5 is a front view of a state in which five LED lamps are installed.

As shown in Figure 1 and 2, the LED lighting fixture 10 for the present embodiment according to the present embodiment is a heat dissipation main body 20, the LED module 40 is installed in the heat dissipation main body 20, LED module ( A cover 60 covering 40.

The heat dissipation body 20 includes a base 21 and a plurality of cooling fins 23 protruding from the upper surface of the base 21.

The LED module 40 is installed on the bottom surface of the base 21.

The LED module 40 is composed of a metal PCB 41 and a plurality of LEDs 43 mounted on the metal PCB 41.

Cover 60 is installed on the base 21, the silicon band 80 is interposed between the base 21 and the cover 60, serves to prevent foreign matter from penetrating from the outside.

In particular, the heat dissipation main body 20 of the present embodiment is molded by magnesium die casting.

Magnesium die-casting is lighter than aluminum die-casting (because of its smaller density per unit volume), and the unit thickness of the cooling fins can be made thinner (because of the high coagulation rate and very fine grain, which makes the product excellent in mechanical properties). There is an advantage.

Therefore, even when supporting a plurality of LED lamps on one arm 1, it is possible to support the arm 1 more stably than aluminum.

In addition, the unit thickness of the cooling fins 23 can be formed thinner, so that more cooling fins 23 can be arranged for the same height and the same length, thereby making the contact area with the outside air much larger, thereby providing heat dissipation performance. This is so excellent that it significantly improves the durability of the LED luminaire.

On the other hand, it is preferable that the side walls 25 and 27 protruding upward are integrally formed on the left and right sides of the base 21.

The side walls 25 and 27 function not only as a protective plate for protecting the cooling fin 23 from external shock but also as a mounting bracket to which the arm mounting bracket 70 described below is mounted.

Therefore, the heat dissipation main body 20 is preferably formed by integrally die-casting the base 21, the cooling fins 23, and the side walls 25 and 27.

In addition, the left and right side walls 25 and 27 are preferably implemented as inclined side walls 25 and 27 that are inclined closer to each other as they are directed upward.

The arm mounting bracket 70 is composed of a first arm mounting bracket 71 installed on the inclined side walls 25 and 27 and a second arm mounting bracket 76 holding the arm 1.

The first arm mounting bracket (71) includes a sliding inclined fitting groove (72) (73) that is slidably fitted in the front-rear direction with respect to the left and right side walls (25) (27), and the first mounting to surround the bottom of the arm (1). The groove 74 is formed.

Therefore, when the sliding inclined fitting grooves 72 and 73 are fitted to the upper end side of the side walls 25 and 27, the installation is restrained so as to prevent the separation of the sliding inclination fitting grooves 72 and 73 outside the front and rear directions.

The first mounting groove 74 serves to position the bottom surface of the arm 1 stably.

The second arm mounting bracket 76 is disposed on the first arm mounting bracket 71 and is fastened and supported by the fastening member 75 on the left and right side walls 25 and 27 and surrounds the upper surface of the arm bar 1. The mounting groove 78 is formed.

As such, the armature mounting bracket 70 is a very useful structure when supporting odd number of LED luminaires such as one, three, five. That is, when the left and right sides of the central LED luminaire are symmetrical, it can be used as one arm mounting bracket 70.

Of course, when supporting an even number of LED luminaires may use two arm bracket mounting bracket (70).

In this way, since one arm mounting bracket 70 is mounted to the LED luminaire in the center, the other LED luminaires in the structure can be further extended to the side.

As an example, a case in which one LED lamp 10 is applied to two LED lamps as shown in FIG. 3 will be described.

As shown in FIG. 3, the LED luminaire includes a first LED luminaire 10A, a second LED luminaire 10B disposed on one side of the first LED luminaire 10A, and a first LED luminaire 10A. A hinge member 30 for pivotably connecting the second LED lamp 10B and a swing angle determining member 50 for determining a swing angle of the hinge member 30 are included.

The hinge member 30 includes a first hinge 31 installed on the first LED luminaire 10A, a second hinge 33 installed on the second LED luminaire 10B, a first hinge 31 and a first hinge. It consists of the hinge axis | shaft 35 which connects two hinges 33. As shown in FIG.

Similarly, the first and second LED lamps 10A and 10B may include first and second heat dissipating bodies including a plurality of first and second cooling fins 23 protruding from an upper surface of the first and second bases 21. 20A, 20B, the first and second LED modules 40 installed on the lower surfaces of the first and second bases 21, and the first and second cover 60 covering the first and second LED modules 40. Include.

The first hinge 31 includes a first base hinge 31a formed at the side of the first base 21 and a first cover hinge 31b formed at the side of the first cover 60.

The second hinge 33 includes a second base hinge 33a formed on the side of the second base 21 and a second cover hinge 33b formed on the side of the second cover 60B.

The hinge shaft 35 is connected to the first base hinge 31a, the first cover hinge 31b, the second base hinge 33a, and the second cover hinge 33b.

Therefore, one hinge shaft 35 pivotally connects the first LED luminaire 10A and the second LED luminaire 10B and at the same time installs and supports the cover 60 to the base 20, thereby assembling the cover. The assembly work is short because the process of assembling the hinge member is completed in one step.

On the other hand, the turning angle determining member 50 is configured to determine the LED luminaire bent at a desired angle at that position.

The turning angle determining member 50 includes a turning angle determining arc piece 51, a position fixing pin 53 for fixing the turning angle determining arc piece 51 to the first LED lamp 10A, and a second LED lamp. It consists of the movable pins 55 which are fixed to 10B.

The positioning pin 53 and the movable pin 55 are inserted into the insertion grooves 26 and 28 formed on the front surface of the side walls 25 and 27.

The turning angle determining circular arc 51 is a circular arc having the same trajectory as the turning trajectory, and an arc long hole is formed therein. In addition, the arc long hole is formed with a plurality of angle control arc so that the angle can be visually adjusted by 5 degrees.

Therefore, after the position fixing pin 53 is inserted into the first LED luminaire 10A and the swing angle determining circular arc 51 is fixed, the position fixing pin 53 is turned after turning the second LED luminaire 10B. 55) is inserted into the angle control arc and then inserted into the second LED luminaire (10B) to maintain the state.

In this way, it is very easy to change the bending position of the LED luminaire, the direction of light (light distribution) can be freely changed, and the light distribution of street lights or security lights can be variously adjusted according to the characteristics of the place.

4 is a view showing a state of use of the three LED luminaires.

This can be installed by the same configuration as above except that the second LED luminaire and the third LED luminaire are arranged on the left and right sides of the central LED luminaire.

Looking at the layout of the three LED luminaires, since the hinge centerline is located on the base and the side of the base, the LED module is inclined even when the pivot angle is greatly deformed, but the middle part is not opened so that the light does not shine.

In addition, when the LED luminaires on both sides are bent and inclined with respect to the central LED luminaire, the amount of light that can reach the road surface may vary according to the position of the LED because the LEDs are strongly straight.

To solve this problem, the LED module driver is applied to each line (1 to 15 lines) to make the amount of light on the road uniform by changing the applied current value.

For example, since one line is farther from the road surface than 6 to 10 lines, the current value of one line is higher than 6 to 10 lines so that the intensity of light becomes stronger, thereby improving the uniformity of the road surface.

5 is a view showing a state of use of the five LED lamps.

This can be installed by the same configuration as above except that the second and fourth LED lamps and the third and fifth LED lamps are arranged on the left and right sides of the central LED lamp.

As such, the number of heat dissipation modules can be increased and the angle can be adjusted to produce high-capacity high-end LED landscape security luminaires.

As described above, although described with reference to a preferred embodiment of the present invention, the present invention can be variously modified or modified without departing from the spirit and scope of the present invention described in the claims Those skilled in the art will appreciate.

The present invention can be applied to any LED luminaire that is suspended from the arm of the pillar.
