Description

LED LIGHTING DEVICE {LED LUMINAIRE}

The present invention relates to an LED lighting device, and more particularly, to an LED lighting device capable of easily mounting a plurality of lights on a wall or a ceiling.

In general, the illumination of a broadcasting camera is largely divided into a mounting type in which the camera is directly mounted, a portable type in which the camera is mounted, and a stationary type. Generally, such a lighting apparatus uses a halogen lamp, a metal halide lamp (HMI) for optical use, a Halogen Metal Iodide (HMI), or an LED (Luminescent Diode).

The double halogen lamp has advantages of easy light source and low cost, but it has a drawback of shortening the duration of battery due to low brightness and high heat generation and heat generation. In fact, a portable light source (Sun-Gun) that uses a large-capacity belt battery for a halogen lamp of 150 W is mainly used in a broadcasting scene.

In this case, however, the energy efficiency of the halogen lamp is low, so that it can not be operated for only about 30 to 40 minutes, and the cost of the separate lighting engineer due to the weight of the belt battery arises. The halogen lamp has a color temperature of about 3400K, which is much different from the color temperature of daylight (5500K).

On the other hand, illumination using an optical metal halide lamp (hereinafter referred to as "HMI") has good color rendering properties, energy efficiency, low calorific value and power consumption, and color temperature of 5600K.

However, since the HMI requires a separate lighting device and requires a little lighting time, it is not suitable for shooting for capturing an instant, and has a disadvantage that it is difficult to carry because it is heavy in weight. As a prior art for overcoming these disadvantages, an illumination device using LED is described in detail in Application No. 10-2009-0068669 (Publication No. 10-2011-0002400 (Published on Jan. 11, 2011)).

However, since the LED lighting using the recently developed LEDs has a long life and the demand is gradually increasing, such LED lighting devices still have the color and light quantity comparable to the level of the indoor lighting device, There are limitations in installing a large area of light on a ceiling or wall of a studio, and there is a limited problem in installing or expanding it with existing lighting.

More particularly, the present invention relates to an LED lighting device which is easy to install on a wall or a ceiling in accordance with the purpose of use, facilitates expandability in a horizontal or vertical direction, And it is an object of the present invention to provide an LED illumination device capable of attaching or detaching and attaching each other.

According to an aspect of the present invention, there is provided a lighting system comprising: a lighting body including a heat radiation sheet having a mounting region formed on a wall, a ceiling, or a separate mounting base, and a fabric layer provided on the other surface of the heat radiation sheet; An illumination body installed on a wall or a ceiling and having a mounting area formed therein, a heat radiation sheet disposed on a back surface of the mounting area, and a rear surface of the heat radiation sheet formed of a fabric material; A plurality of LED modules for emitting light of at least two color temperatures are formed in a pattern set on a flexible printed circuit board, a light source arranged in the mounting area, and a light source provided at each corner of both sides of the lighting body, And an engaging portion having one of a male velcro or an arm velcro at a rear edge portion of the illuminating body and the other of the male velcro or the arm velcro at an upper corner of the illuminating body. A light emitting diode (LED)

Wherein the light source includes a first LED module having a first set color temperature range and a second LED module having a second set color temperature range having a color temperature higher than the first set color temperature range, The modules may be elongated in the longitudinal direction and arranged alternately with each other.

The first LED module and the second LED module may be selectively turned on, simultaneously turned on, or turned on at a predetermined rate to implement a specific color temperature.

The coupling part may include one selected from the group consisting of male velcro and arm velcro on the rear edge of the lighting body, and the other of the male velcro or the arm velcro may be provided on the upper edge corner of the lighting body.

The lighting unit may be coupled to the wall unit, the ceiling, or other adjacent lighting units in a plurality of directions by the coupling unit in the horizontal or vertical direction.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms and words used in the present specification and claims should not be construed to be limited to ordinary or dictionary meanings, and the inventor should appropriately define the concept of the term to describe its own design in the best way possible It should be construed as meaning and concept consistent with the technical idea of the present invention.

2 is a rear view showing the LED lighting apparatus 100 shown in FIG. 1 from the rear, and FIG. 3 is a plan view showing the LED lighting apparatus according to the embodiment of the present invention. FIG. 1 is a side view showing the LED illumination device 100 shown in side view.

1 to 3, an LED illumination apparatus 100 according to an embodiment of the present invention includes an illumination body 110 installed on a wall or a ceiling or a separate stand, a light source 110 mounted on the illumination body 110, And a coupling unit 130 provided on the illumination body 110 and detachably attaching the illumination body 110. [

(Not shown), which is detachably mounted in front of the illumination body 110, and includes a diffusion plate for diffusing light provided from the light source 120, although not shown in the figure.

As shown in FIG. 1, it is preferable that the illumination body 110 has a rectangular shape. It goes without saying that the present invention can be implemented in a circular or other polygonal shape. The number of the light sources 120 can be increased and the arrangement of the light sources 120 can be easily expected by forming the illumination main body 110 in the shape of a rectangle only.

The lighting body 110 includes a heat dissipation sheet 111 formed of a material having excellent heat dissipation performance and having a mounting region 112 on which the light source 120 is disposed, And a fabric layer 113 made of a fabric material.

The heat-radiating sheet 111 may be formed of a metal material or a non-metal material having a thin plate shape and having excellent thermal conductivity, and may be formed of a flexible material. The fabric layer 113 functions to prevent the conductive heat dissipated from the heat-radiating sheet 111 from being directly exposed to the user. The heat radiating sheet 111 and the fabric layer 113 are formed with through holes 114 communicating with the outside so that the light source 120 and the power supply terminal (not shown) can be connected.

Accordingly, the lighting body 110 is thin and light, and can be bent in accordance with the shape of the mounting surface.

The light source 120 is composed of an LED module having at least two or more color temperatures. In the present invention, an LED module having two color temperatures will be described as an example.

The light source 120 includes a first LED module 121 and a second LED module 122 and is disposed in the mounting area 112.

At this time, the first LED module 121 has a first set color temperature range, and the second LED module 122 has a second set color temperature range. The first set color temperature range is formed to have a lower color temperature than the second set color temperature range.

For example, the first set color temperature range may be about 2400 to 3500K, and the second set color temperature range may be about 4500 to 6000K. The first set color temperature range may represent a warm color temperature of the red system, and the second set color temperature range may express a white system or a cold color temperature.

For reference, the unit of color temperature is K (Kelvin) as the absolute temperature, and the candle is about 2200K, the sodium lamp about 3000K, the white fluorescent lamp about 4000K, the noon sun or the cold white fluorescent lamp about 5800K, It has a color temperature of about 7000K. Of course, the color temperature of the first LED module 121 and the second LED module 122 may be selectively changed in the range of 2000 to 8000K. The first LED module 121 and the second LED module 122 are formed of a high color LED module having a color rendering index (CRI) of 90 or more, Can be displayed in a similar manner.

Accordingly, when only the first LED module 121 is lit, the first LED module 121 emits a warm color temperature. When only the second LED module 122 is lit, the color temperature of the first LED module 121 And the second LED module 122 may be turned on at the same time or may be controlled to blink by mixing the color temperature. Thus, it is possible to adjust the color temperature depending on the situation, and more effective color temperature can be provided.

In order to effectively implement the color temperature, it is preferable that the first LED module 121 and the second LED module 122, which are elongated in the longitudinal direction, are installed on the mounting region 112 in a pattern in which the LED modules 121 and 122 are alternately arranged. Or a pattern in which different color temperatures are arranged for specific areas.

Since the first LED module 121 and the second LED module 122 are installed on a flexible printed circuit board (FPCB) (not shown), the first LED module 121 and the second LED module 122 can be installed to be bent together with the lighting body 110, And can be installed easily in response.

The engaging portion 130 includes male and female Velcro and is disposed at each corner portion 115 on both sides of the illumination body 110.

The male and female velcro can be selectively disposed on the corner portions 115 of both sides of the illumination body 110. More preferably, The velcro is disposed, and the male velcro is disposed at the corner of the other surface. In order to facilitate the installation of the lighting body 110 when a wall surface or a ceiling or the like is formed on the installation surface, an arm velcro of a soft material is disposed on the upper surface of the lighting body 110, It also has the effect of preventing external accidents and safety accidents such as abrasions.

When the coupling part 130 is disposed on both sides of the lighting body 110, the lighting body 110 can be easily attached to and detached from the installation surface, It is easy to expand.

The illumination body 110 includes a coupling hole 116 penetrating a portion where each corner portion of the illumination body 110 meets and an eyelet 117 surrounding the inner circumference of the coupling hole 116. Here, the eyelet (117) is a hole, which means a hole or a hole of a belt that fixes a metal banded leather strap. It also refers to the metal shape of the round frame attached to it (see [Encyclopedia of Naver Knowledge] (see the Fashion Dictionary Dictionary, August 25, 1997, Korean Dictionary).

The coupling holes 116 are formed so as to bind the plurality of illumination bodies or to provide a strong coupling force, so that screws or hooks are fastened. At this time, since the illumination body 110 has a thin structure, the eyelet 117 can prevent the deformation of the illumination body 110 in a fixed state through the coupling hole 116, It is possible to minimize the occurrence of damage to the illumination main body 110 due to the fixing screws or hooks.

FIG. 4 is a reference view showing a state in which the LED lighting apparatus 100 shown in FIG. 1 is connected in the lateral direction, and FIG. 5 is a sectional view of the LED lighting apparatus 100 shown in FIG. Fig.

4 and 5, there is shown an example in which the illumination main body 110 is extended in the horizontal or vertical direction.

4, the LED illumination apparatus 100 includes a first illumination body 110 on a wall or a ceiling, a second illumination (not shown) disposed laterally adjacent to the first illumination body 110, The main body 110a is attached by the first lighting body 110 and the engaging portion 130. [ Here, the first illuminating main body 100 represents the same components as the illuminating main body 110, and is used merely for distinguishing the second illuminating main body 110a from the second illuminating main body 110a.

A male velcro formed on the corner portion 115 'of the second illumination body 110a is attached to the upper side of the arm velcro formed on the corner portion 115 of the first illumination body 110, ) Is attached to the mounting surface.

Similarly, as shown in FIG. 5, the illumination main body 110 can be installed in the horizontal or vertical direction with respect to a wall, a ceiling, or a plurality of adjacent illumination bodies. If a plurality of the lighting units are extended and installed, a light source having different color temperatures may be provided for each lighting unit to emit colorful lights. Also, since it is easy to attach and detach and is light in weight, have.
