Description

Led lighting fixtures

The present invention relates to an LED lighting device, and more particularly, to a construction cost, and to an LED lighting device that can adjust the light distribution according to the surrounding environment.

In general, each country has a standard for illuminance of roads where street lamps are installed, and this applies regardless of the road environment such as fluctuations in the width of the road or curves or straight sections.

The light output of the street lamp used according to the illuminance criteria is determined. At this time, the height of the street lamp post, the elevation difference of the road surface, the curved road, etc., are variables that change the illuminance of the road surface even when the street light having the same light output is used.

In other words, the farther the distance from the light source of the street light to the road, the lower the illuminance of the road. Considering this, High Mast, which is higher than ordinary street lamp posts, should use a light source with higher light output.

Street lamps are usually installed along both edges of the road, but recently, a strut is placed on the central separator of the road and a combination of luminaires in various directions has been used.

For example, it can be seen in the representative diagram of the Utility Model Registration No. 20-0311443 (Landscape, April 11, 2003).

* The reason for using a high mast is to increase the area of illumination for a single street light, reducing the installation cost by making the distance between the street lamps farther than that of ordinary street lights.

For example, if the distance between the regular street light is 50m interval when using a high mast 20 to 30m height can be installed at intervals of 80m or more can reduce the construction cost.

High mast lighting fixtures are described in US Patent Publication No. 2013-0193856, published August 1, 2013, systems and methods for providing high-mast lighting.

The U.S. Patent Publication is configured to include a light source unit capable of emitting light in a 360 degree direction on top of the high mast support.

However, since the conventional high-mast lighting fixtures have a constant light distribution, the uniformity of illuminance may not be partially secured according to the conditions of the road, such as the width of the road, the curved section, or the section having an elevation difference. In particular, when installed on a narrow road, there is a problem that can cause light pollution by irradiating light to a nearby residence.

In addition, although the light is arranged in a circular shape to form a light distribution surface in the 360-degree direction based on the high mast support, there is a problem that excessive illumination is provided on the side of the center divider, thus increasing power consumption.

In addition, the center of the road may be provided with a separation zone, but may form a separation area having a predetermined width. In the case of a conventional high-mast luminaire, since most light is irradiated to the separation area, the separation area may be brighter than the road. There was a problem that occurred.

The problem to be solved by the present invention in consideration of the above problems is to provide an LED lighting fixture that is easy to adjust the light distribution according to the installation environment.

In another aspect, the present invention provides an LED lighting fixture that can easily change the light output to meet the illuminance required value at the installation position.

And the present invention is to provide an LED lighting fixture that can ensure the uniformity of illumination.

LED lighting apparatus of the present invention for solving the above problems, each of which includes a plurality of optical module unit 110, provided with a support 120 for determining the inclination angle and direction of the optical module unit 110 Is connected to a plurality of lighting module unit 100, the connection portion 130 provided in the center of the back of the lighting module unit 100 is an angle adjusting unit 200 that can adjust the vertical angle of the lighting module unit 100 And a power supply unit 300 connected to the angle adjusting unit 200 to supply power to the lighting module unit 100 inside.

The LED lighting apparatus of the present invention uses one or more LED lighting module units, and adjusts the light distribution of each of the optical module units by varying the angles of the support units supporting the optical module units disposed in the LED lighting module unit. It has the effect of providing illumination of one illumination.

In addition, the present invention by replacing the support parts or by adjusting the angle of the support parts to provide the illumination of a uniform uniform illumination only where the lighting, such as road in the installation position, it is possible to provide illumination of the prescribed illumination while minimizing the light output. Therefore, there is an effect that can prevent the occurrence of light pollution.

In addition, the present invention uses a plurality of LED lighting module unit, there is an effect that it is easy to adjust to the light output required at the location by removing or attaching the LED lighting module unit as necessary.

1 to 3, respectively, LED lighting apparatus according to a preferred embodiment of the present invention, each including a plurality of optical module unit 110, the support portion for determining the angle of the optical module unit 110 ( An angle that can be adjusted to the vertical angle of the illumination module unit 100 having a plurality of lighting module unit 100 having a 120, and the connection portion 130 provided in the center of the back of the lighting module unit 100, the illumination module unit 100 It is configured to include an adjustment unit 200, the power supply unit 300 is connected to the angle adjustment unit 200 to supply power to the lighting module unit 100 inside.

Hereinafter, the configuration and operation of the LED lighting device according to a preferred embodiment of the present invention configured as described above in more detail.

First, the present invention includes at least two or more lighting module unit 100.

Each of the lighting module units 100 is coupled to a case portion 140 having one surface open, a plurality of support portions 120 disposed at an inner upper center of the case portion 140, and an upper portion of the support portion 120. The light distribution is determined according to the inclination direction and the angle of the support unit 120, the optical module unit 110 including a plurality of LEDs, and is provided along the edge of the support unit 120 to supply external power to the optical module unit A wiring board 150 for supplying to each of 110, a cover part 160 covering an open surface of the case part 140, and a central portion of an upper surface of the case part 140 is provided in the angle adjusting part 200. Is configured to include a connecting portion 130 is connected, a plurality of heat radiation fins 141 is formed on the outer surface of the case portion 140.

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

The lighting module units 100 are disposed at predetermined angles along the arc direction with respect to the angle adjusting unit 200 so that the respective light emitting surfaces are emitted in different directions of the light emitted from each other to illuminate different positions on the ground. It is composed.

As described above, illumination of a wider area is enabled by the orientation angle of the lighting module unit 100.

A plurality of optical module units 110 may be arranged in a line inside the lighting module unit 100, and the optical module units 110 may include a substrate, an LED mounted on the substrate, and the LEDs. It may be configured to include a reflector for reflecting and condensing the emitted light of the), such a structure will be described in more detail later.

Each of the optical module parts 110 is fixed to the inner upper surface of the case part 140 by the support part 120, and each of the support parts 120 has an inclined surface (a surface in contact with the optical module part 110). 121). The inclined surface 121 has different angles and inclined directions in one lighting module unit 100.

The direction angles of the optical module parts 110 supported by the support parts 120 having the inclined surface 121 are different from each other. Therefore, each of the lightable areas can be illuminated by the direction angle of the light module part 100. Each of the optical module units 110 may be divided into areas to be illuminated.

Referring to FIG. 5, when using four lighting module units 100, each of the lighting regions of the lighting module units 100 is A, B, C, and D.

When the lighting module units 100 are installed, the opening surface of the case unit 140 may be set according to the direction of the light outlet, and the angle of the lighting module units 100 may be adjusted using the angle adjusting unit 200. By adjusting, the illumination area shown in FIG. 5 can be moved.

That is, when the present invention is installed in the central separation area of the road, the road may be illuminated by adjusting the vertical angles of the lighting module units 100 according to the width of the central separation area.

In such a structure, the inclination angles of the optical module units 110 are determined by the inclined surfaces 121 of the support units 120 supporting the optical module units 110 in each of the lighting module units 100.

In this case, when the area illuminated by one lighting module unit 100 is A, the lighting regions of the plurality of optical module units 110 provided in the lighting module unit 100 are all located within the lighting region A, The illumination area A is divided by the number of the optical module units 110 so that each optical module unit 110 may illuminate the divided illumination areas a11 to a44, respectively.

Therefore, since the illumination areas a11 ˜ a44 of the optical module parts 110 may be overlapped with each other as much as possible, the illumination area A of the lighting module part 100 may be illuminated with uniform illumination.

In the above example, when the installation position of the present invention is E, the lighting areas B and C that are relatively close to the installation location are larger than the lighting areas A and D that are relatively far from each other. Illumination areas a11, a12, a13, a14, a21, a31 of the illumination areas a22, a23, a24, a32, a33, a34, a42, a43, a44 of the optical module unit 110 closer to E It is desirable to have a larger area as compared with (a41).

The division of the area takes into account that the illuminance decreases as the distance increases when the light output of each optical module unit 110 is the same.In the case where the distance is relatively far, the illumination angle is reduced by narrowing the irradiation angle of light to reduce the beam width. The lowering phenomenon can be reduced.

Since the optical module units 110 are respectively supported by the support unit 120, when the wires are directly connected to the substrate of the optical module unit 110 from the outside, the wires corresponding to twice the number of the optical module units 110 are formed. The number of wires is difficult to install because they must be connected, and the light efficiency can be reduced by such wires.

In order to prevent this, a wiring board 150 is installed at both edges of the inner upper center surface of the case part 140 in which the support part 120 is installed, and external power is supplied to the wiring board 150 to provide the wiring. Wiring is formed to be connected to each substrate of the optical module unit 110 through the substrate 150.

The support unit 120 for supporting each of the optical module unit 110 is preferably made of a metal material to facilitate heat dissipation of heat generated from the optical module unit 110, and it may be necessary to change the light distribution according to the specificity of the installation place. At that time, it is replaced by another support having different inclination directions and angles so as to have a light distribution suitable for the installation site.

The support 120 may use an adjustable structure that can adjust the inclined direction instead of a replaceable type.

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

Referring to FIG. 6, the support part 120 is rotatably coupled to an upper part of the fixing part 122 fixed to the case part 140 and the fixing part 122, and an upper part of the rotating part having an inclined surface 121 ( 123).

By such a configuration, the inclination direction of the optical module unit 110 attached to the inclined surface 121 of the rotating unit 123 can be changed according to the rotation of the rotating unit 123, and the light distribution can be adjusted to desired light distribution.

When the light distribution can be adjusted, it is possible to prevent the generation of light pollution and to illuminate the illumination area with uniform illumination.

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

Referring to FIG. 7, the substrate 111 may be seated and fixed on the inclined surface 121 of the support part 120, the LEDs 112 mounted on the substrate 111, and the LEDs 112 may be emitted from each of the LEDs 112. And a reflecting portion 113 including a light reflector 114 reflecting light, respectively.

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

The reflector 113 does not reflect light emitted from all LEDs as in a conventional reflector, and the LEDs 112 are disposed one by one inside each light reflector 114, so that the light of each LED 112 may be disposed. By reflecting the desired light distribution can be obtained.

In addition, the reflective module 113 having a single structure is fixedly installed on the substrate 111 fixed to the supporter 120 without installing a reflective module for each of the LEDs 112, thereby providing light to each of the plurality of LEDs 112. The individual reflections make the assembly easier.

It will be apparent to those skilled in the art that the present invention is not limited to the above embodiments and may be variously modified and modified without departing from the technical spirit of the present invention. will be.

The present invention is easy to adjust the angle to provide an illumination of a uniform uniform illumination only in the place where the lighting, such as road in the installation position, it is possible to provide illumination of the prescribed illumination while minimizing the light output, preventing the occurrence of light pollution It can be used industrially.
