Description

{LED lighting device}

The present invention relates to an LED lighting device, and more particularly, to an LED lighting device embedded in a ceiling.

BACKGROUND ART [0002] Generally, illumination devices including an LED illumination device basically take a form of emitting light at a surface for diffusion. This is common to both the bulb type illuminating device, the surface illuminating device, and the stand type illuminating device, and the beauty of illumination is determined not by the light itself but by the specificity or color of the external design of the illuminating device.

As an example of the surface emitting type illumination device, the surface illuminating device uses a diffusion plate having a predetermined area as a cover. An example of this is Registration No. 10-0998980 (registered on Dec. 1, 2010). 4, which is a representative drawing of the above-mentioned patent, includes a substrate on which a plurality of LEDs are arranged to emit light upward, and at least one diffusion layer is included on the upper side of the substrate, So as to illuminate the entire surface of a specific size with a uniform illumination.

Such a structure is a general construction of a conventional illumination device that emits light from the surface described above. The diffuser plate prevents the light from being partially emitted intensively, thereby preventing the occurrence of glare. However, . This lowering of the light efficiency causes the energy consumption efficiency of the lighting apparatus to be lowered because more power must be used for lighting of the same illuminance.

That is, in order to provide a planar light source of sufficient illumination, a large number of LEDs must be used more than necessary, so that the advantage of low power consumption of the LED illumination is reduced and it is not easy to handle heat emitted from the LED, There is a problem in that the life of the battery can be shortened.

Background Art [0002] As a prior art for a ceiling embedded lighting which is generally called a 'down light', a structure and an action of a down light are described in detail in a registered patent 10-1143344 (registered as of April 30, 2012) .

1 is a representative view of the above-mentioned Patent No. 10-1333344.

1, a conventional LED light device includes a printed circuit board 4 on which LEDs 5 are mounted, a heat sink 5 for radiating heat emitted from the LEDs 5 on the printed circuit board 4, A heat sink 1 having a plurality of 'C' shaped screw grooves formed on the radiating fins to be coupled to the back surface of the heat sink 1, and a heat sink 1 having a cylindrical shape with the upper and lower openings thereof coupled with the printed circuit board 4 and the heat sink 1 An illumination cylinder 7 in which a step 2 is formed on an inner circumferential surface on the upper side so as to be mounted and a plurality of guide grooves are formed on an outer circumferential surface of the illumination cylinder 7 and a transparent or translucent cover lens 11 (Not shown).

And a heat sink (3) for transferring the heat of the printed circuit board (4) to the heat sink (1).

A separate heat sink 1 is used to dissipate the heat generated in the printed circuit board 4 and the heat sink 1 And the heat sink 3 capable of transmitting heat between the printed circuit board 4 and the printed circuit board 4 are used.

This is because the LEDs 5 mounted on the printed circuit board 4 are uniformly spaced apart from each other, and therefore, it is difficult to discharge the heat, thus requiring a complicated heat dissipation structure.

Also, since the heat sink 1, the illumination cylinder 7, and the heat sink 3 are separately manufactured and then assembled, the time and cost required for fabrication are increased.

In the conventional drawings and the like, there is no mention of a power supply device for supplying a DC constant power source to the LED 5, and in this case, it is understood that the power supply device is installed outside the illumination cylinder 7 of the prior art .

Therefore, when the power supply unit is to be installed at a different position, the power supply unit must be connected to the printed circuit board 4, which requires a separate wiring work.

FIG. 2 is a configuration diagram of an LED illumination apparatus according to a preferred embodiment of the present invention, FIG. 3 is an exploded perspective view of FIG. 2, and FIG. 4 is a sectional view of FIG.

Referring to FIGS. 2 to 4, the LED illumination apparatus according to the preferred embodiment of the present invention includes a lower housing 200 having a light outlet 210 on its bottom surface and a diameter gradually decreasing toward the top, A power supply unit 140 is inserted into the upper part of the lower housing 200 and a substrate 300 on which the LED 310 is mounted is coupled to an upper surface of the upper housing 100 And a diffusion plate 240 seated on the seating surface 230 of the lower housing 200.

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

First, the upper housing 100 is integrally formed of a metal material. The lower surface of the upper housing 100 is opened. A space 120 through which the power supply unit 140 can be inserted is provided inside the opened bottom surface.

The upper housing 100 is circular in shape and has a circular opening on the bottom of the housing and has a predetermined seating surface 160 around the opening and a plurality of radiating fins 130 protruding from the seating surface 160 .

A plurality of fastening protrusions 150 protrude outside the seating surface 160 and are fastened by fastening means such as a bolt and the like to the lower housing 200 to be described later.

A hole 101 can be formed in a part of the upper side of the upper housing 100 so that the space part 120 can communicate with the outside and the electric wire 500 is connected And may be supplied to the power supply unit 140.

The power supply unit 140 receives external power and supplies DC power to the substrate 300. The neighboring LED lighting apparatus can be connected to the power supply unit 140 through a power connection unit 110. [

The AC power supplied to the power supply unit 140 may be supplied through the power connection unit 110 and the DC power may be supplied to the power supply unit 140 of the neighboring LED lighting apparatus through the electric wire 500 have.

The top edge of the substrate 300 is seated on the seating surface 160 of the upper housing 100 and tightly fixed to the seating surface 160 by bolts or an adhesive.

The heat generated from the plurality of LEDs 310 mounted on the substrate 300 can be easily conducted to the heat dissipation fins 130 through the substrate 300 and the seating surface 160 to be dissipated.

In order to increase the efficiency of heat dissipation, it is preferable to use a metal PCB as the substrate 300.

The plurality of LEDs 310 mounted on the substrate 300 may be disposed at a lower side of the seating surface 160 rather than being located at the center of the substrate 300.

It can be understood that the heat generated from the LEDs 310, which are substantially heat sources, is conducted in the direction of the rectilinear direction to enhance the heat radiation effect.

The lower housing 200 is coupled to the lower portion of the upper housing 100.

The overall shape of the lower housing 200 is such that the inner diameter becomes wider as it goes down. A step is provided in a part of the inner diameter of the lower housing 200 to form a seating surface 230 on which the diffusion plate 240 is seated.

The lower housing 200 is preferably integrally formed of a resin material.

The lower end of the lower housing 200 is formed with a downwardly convex anti-glare part 220. The anti-glare unit 220 reflects the light diffused by the diffusion plate 240 so that the light does not directly enter the eye of the human body, and may have appropriate light distribution.

A plurality of fastening protrusions 250 are provided on the upper side of the lower housing 200 and fastening means such as bolts are fastened in a state of facing the fastening protrusions 150 provided in the upper housing 100, .

In this structure, the light emitted from the LED 310 is diffused by the diffusion plate 240 positioned at the middle of the height of the lower housing 200 to provide a planar light source, A diffusion pattern portion 241, which is an uneven surface, is provided in the central portion to facilitate diffusion of light.

The light diffused by the diffusion plate 240 is emitted to the outside through the light outlet 210 of the lower housing 200.

The diffusion plate 240 is not fixed to the seating surface 230 of the lower housing 200 by a separate fastening means but is fixed in a fitted state.

The effect obtained by not using the fastening means as described above is that the structure is simplified since it is not necessary to form a structure such as a bolt insertion hole in order to fasten the fastening means, and when the fastening using a fastening means such as a bolt is used, And the productivity is prevented from being lowered due to an increase in the time required for manufacturing.

To this end, the lower housing 200 is made of a resin material and integrally injected in the present invention. In this case, considering that the lower housing 200 is relatively higher in temperature immediately after the injection and the temperature is lowered with time, the temperature of the lower housing 200 may be slightly shrunk, (240) until it abuts against the seating surface (230).

As described above, when the lower housing 200 is at a relatively high temperature after injection, the diffusion plate 240 is easily press-fitted. When the lower housing 200 is cooled to room temperature, the diffusion plate 240 is finely contracted, So that it is possible to firmly fix the base 240.

Therefore, the present invention can fix the diffusion plate 240 without using a separate fastening means.

Alternatively, the diffusion plate 240 may be press-fitted and fixed in a state where the lower housing 200 is completely cured.

A fixing part 400 for fixing the lower housing 200 to the ceiling is installed at a part of the outer surface of the lower housing 200. At this time, the pivot portion 410 constituting the fixing portion 400 may be formed integrally with the lower housing 200, and the elastic pivot portion 420, which is metallic and can rotate about the pivot portion 410, And can be fitted and fixed to the turning portion 410.

In addition, it may further include a ring 430 for securing stability against disasters such as more rigid fixing and earthquake.

FIG. 5 is a configuration diagram of an LED illumination apparatus according to another embodiment of the present invention, and FIG. 6 is a sectional configuration diagram of FIG.

2 and 4, the LED lighting apparatus according to another embodiment of the present invention includes a lower outer light outlet 210 of the lower housing 200, And a cylindrical diffusion unit 600 extending downward from the periphery of the diffusion plate 600.

The diffusion unit 600 is a diffusing plate that diffuses and emits incident light, and can be realized with a translucent material.

Therefore, the user can not directly see the direct light emitted from the LED 310, so that the glare can be prevented and the illumination can be made more smooth.

In addition, since the diffusion unit 600 can adjust the transmittance and the diffusion ratio, it is possible to adjust the light distribution on the ceiling side so that the ceiling of the surrounding area where the present invention is installed can be illuminated.

In addition, a partition display unit 610 having a predetermined color is disposed under the diffusion unit 600.

The divisional display unit 610 serves to represent a zone where the present invention is installed.

As a specific example, the partition display unit 610 can display colors in various ways, and by providing the present invention having the partition display units 610 of different colors in each of the disabled, female only, and general parking spaces in the underground parking lot, It makes it easy to judge the parking area from a distance.

In addition, when installed in a general office, each division can be distinguished by the color of the division display unit 610, and if the same is installed in the factory, the production line can be easily distinguished.

In addition, when used as a lighting for a large bookstore, children, infants, teenagers, hobbies, novels, and non-fiction can be displayed in the color of the division display unit 610 according to classification of book, do.

As described above, according to the present invention, it is possible to prevent the glare by adding the diffusion unit 600 and to use the LED display unit as a display unit of the compartment by providing a partition display unit 610 that can display a color on a part of the diffusion unit 600 do. The partition display unit 610 may be colored with a specific color.
