Description

LED lighting device}

The present invention relates to an LED lighting device, and more particularly, to an LED lighting device capable of reducing a construction cost and controlling a light distribution according to a surrounding environment.

In general, the standards for road lighting with street lights are set in each country, and this is applied irrespective of the road environment such as the width of the road, the curve or the straight line.

The light output of the street lamp is determined according to the illuminance standard. At this time, the height of the street lamp, the height difference of the road surface, and the curved road are variables in which the illuminance of the road surface is changed even if a streetlight having the same light output is used.

That is, as the distance from the light source of the streetlight to the road becomes farther away, the illuminance of the road becomes lower. Considering this, high masts, which are higher in height than ordinary streetlamps, should use light sources with higher light output.

Typically street lamps are installed along both sides of the road, but recently, a method has been used in which a support is placed on a median separator of a road and a luminaire is combined in various directions in the support.

For example, it is a structure that can be seen in a representative drawing of the registration utility model 20-0311443 (street lamp apparatus, April 11, 2003).

The reason for using the high mast is that it increases the area that can be illuminated by one streetlight, which makes the distance between the streetlights farther than that of the ordinary streetlight, thereby reducing the installation cost.

For example, if the distance between the ordinary street lamps is 50 m, if the high mast having a height of 20 to 30 m is used, it can be installed at an interval of 80 m or more, so that the construction cost can be reduced.

Hi-mast lighting fixtures are described in U.S. Patent Application No. 2013-0193856, published Aug. 1, 2013, systems and methods for providing high-mast lighting.

The above-mentioned U.S. Patent No. 5,101,205 includes a light source unit capable of emitting light in a 360-degree direction on an upper portion of a high-mast support.

However, since the conventional high-mast lighting apparatus has a uniform luminous intensity distribution, uniformity of illuminance can not be partially obtained depending on road conditions such as road width, curved section, and elevation difference section In particular, when installed on a narrow road, there is a problem that light may be irradiated to a nearby residence to cause light pollution.

In addition, although the illumination unit is arranged in a circular shape in order to form a light distribution surface in the direction of 360 degrees with respect to the high mast support body of light, there is a problem that excessive illumination is provided on the side of the median separation unit, thereby increasing power consumption.

In the conventional high-mast lighting apparatus, since most of the light is irradiated to the separation region, the separation region is illuminated more brighter than the road. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide an LED lighting apparatus which can easily adjust the light distribution according to the installation environment.

It is another object of the present invention to provide an LED lighting device capable of easily changing the light output so as to meet the illuminance requirement value at an installation position.

It is another object of the present invention to provide an LED lighting device capable of ensuring uniformity of illuminance.

In order to solve the above-mentioned problems, the LED lighting apparatus of the present invention includes a plurality of optical module units 110 on the inner side, respectively, and a supporting unit 120 for determining the inclination angle and direction of the optical module unit 110 And an angle adjusting unit 200 connected to the connection unit 130 provided at the center of the rear of the lighting module units 100 to adjust the angle of the lighting module units 100 in the vertical direction, And a power supply unit 300 connected to the angle adjusting unit 200 and supplying power to the illumination module unit 100 on the inner side.

The LED lighting apparatus of the present invention may use one or more LED lighting module units to adjust the light distribution of each of the optical module units by varying the angles of the supports for supporting the optical module units disposed in the LED lighting module unit, It is possible to provide illumination of a single illumination.

Further, according to the present invention, it is possible to provide illumination of uniform illumination even when the light output is minimized by adjusting the angles of the support portions or by adjusting the angle of the support portions, , It is possible to prevent the occurrence of light pollution.

In addition, according to the present invention, a plurality of LED module units are used, and if necessary, the LED module module can be attached or detached to easily adjust the light output required at the corresponding position.

Hereinafter, the LED lighting apparatus of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of an LED lighting device according to a preferred embodiment of the present invention, FIG. 2 is a side view of FIG. 1, FIG. 3 is a structural view of an LED lighting module, and FIG. 4 is an exploded perspective view of FIG.

Referring to FIGS. 1 to 3, the LED lighting apparatus according to the preferred embodiment of the present invention includes a plurality of optical module units 110 inside the optical module unit 110, and supports the optical module unit 110 120 that are connected to a connection part 130 provided at the center of the rear surface of the lighting module parts 100 to adjust the angle of the lighting module parts 100 in the vertical direction, And a power supply unit 300 connected to the angle adjusting unit 200 and supplying power to the illumination module unit 100 on the inner side.

Hereinafter, the structure and operation of the LED illumination device according to the preferred embodiment of the present invention will be described in detail.

First, the present invention includes at least two lighting module parts 100.

Each of the lighting module parts 100 includes a case part 140 having one opened side, a plurality of supporting parts 120 disposed in the upper center of the inside part of the case part 140, The optical module unit 110 includes a plurality of light emitting diodes (LEDs) 110 and a plurality of light emitting diodes (LEDs) 120 and is disposed along an edge of the support unit 120, A cover unit 160 covering the open side of the case unit 140 and a cover plate 160 provided at the center of the upper surface of the case unit 140 to cover the openings of the angle adjusting unit 200, And a plurality of radiating fins 141 are formed on an outer surface of the case part 140. [

In such a structure, the case parts 140 of the lighting module parts 100 are disposed with a difference in the directing angle.

Each of the illumination module units 100 is disposed at a predetermined angle along the arc direction with the open sides of the angle adjustment unit 200 as a center, and is emitted in the other direction of the light emitted from each of the illumination module units 100, .

As described above, the illumination angle of the illumination module unit 100 enables illumination with a wider area.

A plurality of optical module units 110 may be arranged in a row inside the illumination module unit 100. The optical module units 110 may include a substrate and LEDs mounted on the substrate, And a reflecting portion for reflecting the emitted light of the light source (not shown) and condensing the light. Such a structure will be described later in more detail.

Each of the optical module units 110 is fixed to the inner upper surface of the case unit 140 by a supporting unit 120. Each of the supporting units 120 has a surface on which the optical module unit 110 contacts, 121). The inclined surfaces 121 are assumed to have different angles and oblique directions in one lighting module unit 100.

The illumination module module 100 includes a plurality of support portions 120 having inclined surfaces 121. The illumination module module 100 includes a plurality of light module modules 110, It is possible to divide an area that can be illuminated by each of the optical module units 110 of the optical module 110.

5 is an explanatory diagram for explaining the light distribution concept of the present invention.

Referring to FIG. 5, when the four illumination module units 100 are used, the illumination regions of the illumination module units 100 are A, B, C, and D, respectively.

This is because the opening face of the case part 140 can be set according to the direction of the light emitting port when the lighting module parts 100 are installed and the angle of the lighting module parts 100 in the vertical direction It is possible to move the illumination area shown in Fig.

That is, when the present invention is installed in the central separation area of the road, the angle of the lighting module parts 100 can be adjusted according to the width of the central separation area to illuminate the road.

The orientation angle of the optical module units 110 is determined by the inclined surfaces 121 of the supporting members 120 supporting the optical module unit 110 in each of the lighting module units 100 in this structure.

At this time, when the area illuminated by one illumination module unit 100 is A, all the illumination areas of the plurality of optical module units 110 provided in the illumination module unit 100 are located within the illumination area A, The illumination area A is divided into the number of the optical module units 110 so that each optical module unit 110 can illuminate the divided illumination areas a11 to a44, respectively.

Accordingly, since the illumination areas a11 to a44 of the optical module units 110 can be avoided from overlapping each other as much as possible, the illumination area A of the illumination module unit 100 can be illuminated with a uniform illumination.

In the above example, when the installation position of the present invention is E, the illumination areas B and C relatively closer to the installation position are wider than the illumination areas A and D relatively far away from each other, A12, a13, a14, a21, a31 (a12, a13, a14, a21, a31) of the illumination area a22, a23, a24, a32, a33, , a41), as shown in Fig.

This division of the area takes into consideration that the illuminance is lowered as the distance increases when the optical output of each optical module unit 110 is the same. When the distance is relatively far, the angle of light is narrowed and the beam width is reduced. It is possible to reduce the phenomenon of lowering.

Since the optical module units 110 are supported by the supporting unit 120, when the electric wires are directly connected to the substrate of the optical module unit 110, electric wires corresponding to twice the number of the optical module units 110 The number of wires is large and the installation is difficult, and the optical efficiency can be reduced by such a wire.

In order to prevent this, a wiring board 150 is provided at both side edges of an inner upper central surface of the case part 140 in which the support part 120 is installed, external power is supplied to the wiring board 150, Wiring is formed so as to be connected to the substrate of each of the optical module units 110 through the substrate 150.

The support 120 supporting each of the optical module units 110 is preferably made of a metal material so as to facilitate heat dissipation of the heat generated from the optical module unit 110 and it is necessary to change the light distribution according to the specificity of the installation site It is replaced with another support having a different inclination direction and angle so as to have light distribution suitable for the installation place.

The supporting part 120 may be of an adjustable structure that can adjust the inclination direction, not the replacement type.

6 is a configuration diagram of another embodiment of the support 120 that can be applied to the present invention.

6, the support part 120 includes a fixing part 122 fixed to the case part 140, a rotation part (not shown) rotatably coupled to the upper part of the fixing part 122 and having an upper surface inclined to the inclined surface 121 123).

The optical module unit 110 attached to the inclined surface 121 of the rotation unit 123 can be changed in the inclined direction according to the rotation of the rotation unit 123 and can be adjusted to a desired light distribution.

When the light distribution can be controlled as described above, it is possible to prevent the occurrence of light pollution and illuminate the illumination area with uniform illumination.

7 is an exploded perspective view of the optical module unit 110 according to the present invention.

Referring to FIG. 7, a substrate 111 is mounted on the inclined surface 121 of the support 120, LEDs 112 are mounted on the substrate 111, And a reflector 113 including a light reflector 114 that reflects light, respectively.

The number of the light reflection apertures 114 is equal to the number of the LEDs 112.

The reflective portion 113 does not reflect the light emitted from the entire LED as in the case of a conventional reflector and allows the LEDs 112 to be arranged inside each of the light reflection holes 114, So that desired light distribution can be obtained.

The reflection unit 113 having a single structure may be fixed to the substrate 111 fixed to the support unit 120 so that the light of each of the plurality of LEDs 112 Since the reflection can be individually performed, the assembling work becomes easier.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention will be.
