Description

{LED Lighting Apparatus}

The present invention relates to an LED lighting device, and more particularly, to a LED lighting device that can be easily manufactured in a desired size, can be assembled and replaced easily, and can be freely installed.

Generally, a lighting device is installed to illuminate at night or in the dark. Various types of such lighting apparatuses have been disclosed. As a recent lighting apparatus, LED (Light Emitting Diode) is widely used instead of a fluorescent lamp or an incandescent lamp.

LEDs are attracting attention because they are semi-permanent, have low power consumption, strong light intensity, and do not emit harmful substances in the manufacturing process.

LED is a kind of diode that emits light when current flows, and it is made by bonding p-type semiconductor and n-type semiconductor to each other.

When a forward voltage is applied to the electrode of the LED, holes, which are p-type multi-carriers, are diffused into the n-region and electrons, which are n-type multi-carriers, are diffused into the p- region. When electrons and holes recombine with each other near the junctions, Light having a wavelength corresponding to the wavelength of the light is generated. At this time, the wavelength of the emitted light differs depending on the material used, and generally, the direct emission type semiconductor has excellent luminous efficiency.

Since such a LED lighting lamp uses a DC power source, it requires a stabilizer for rectifying a commercial power source of 220 V or 110 V to DC and converting the rectified DC power to a size required for lighting.

The ballast can be installed inside an LED lighting fixture, or it can be installed in an LED lighting fixture that is combined with an LED lighting fixture.

The LED lighting device using LED lighting is built-in which uses only LED lighting lamp with built-in stabilizer, the external stabilizer is installed in LED lighting fixture, it uses only LED lighting, and LED lighting with built-in ballast and LED lighting without ballast It can be divided into usable compatible types.

When such an LED lighting apparatus is used in a room, it is inserted and fixed in a certain case. A plurality of LEDs are provided on a substrate. The substrate is accommodated in a case, and a power supply device for supplying power to the substrate is coupled to the case.

However, the conventional LED lighting device has a specification at the time of manufacture, and when it is desired to change to another standard, the size of the LED lighting device is limited since it is troublesome to manufacture it separately.

In addition, conventionally, when the LED lighting apparatus is installed on a ceiling, the bracket is fixed through a fastening member such as a bolt or a screw, There is a problem that the installation work is very troublesome because the lighting device is assembled to the bracket again with the fastening member.

In this state, The apparatus 1 is slidably inserted and connected and a plurality of lighting apparatuses 1 are connected to each other by using a fastening member via a mounting piece 43 of a closing member 40 formed at an end of the LED lighting apparatus 1 .

Further, when a plurality of LED lighting apparatuses 1 are installed in the signboard 100, it is not necessary to provide the cover 30, and the LED substrate 10 can be directly seen.

FIG. 8 is an assembled perspective view showing the structure of the closure member 40 different from that of FIG. 1, in which the closure member 40 is formed into a substantially rectangular shape instead of a curved upper portion as in FIG. can do.

9 and 10, as another embodiment, the present invention has a structure further comprising a support member 90 made of a metal material (for example, steel or the like).

More specifically, the support member 90 having a curved shape is inserted and supported inside the lower support surface 23 of the base member 21. The support member 90 has a first A second surface 92 formed by being bent at both sides of the first surface 91 and a third surface 92 formed by being bent at both sides of the first surface 91 in the other direction 93).

When the support member 90 is inserted through the one end of the frame 20, the support member 90 is easily inserted while sliding.

One or more heat dissipation holes 91a are formed on the first surface 91 of the support member 90 with a space therebetween so that the heat generated from the LED substrate 10 can easily dissipate.

9 and 10, a fitting portion 91b for engaging the ballast 60 is protruded and formed on one end side of the inner surface of the first surface 91, and on the other side, (91c) is formed.

As shown in Fig. 13, one fitting piece of the ballast 60 is fitted, and the other fitting piece of the ballast 60 is screwed into a screw Through the fastening hole 91c of the support member 90 through the fastening member such as the fastening member.

In other words, as shown in FIG. 4A, when the LED lighting apparatus 1 is installed on the ceiling and power is supplied to the LED lighting apparatus 1, heat is generated in the LED substrate 10, The LED lighting apparatus 1 itself may be bent toward the ceiling due to the heat, but it can not be bent by the ceiling and seems to maintain its shape. Conversely, when the LED lighting apparatus 1 is turned off, A phenomenon may occur that the lighting device 1 is cooled while being bent to the opposite side of the ceiling so that the closure member 40 provided at both ends is opened to the ceiling scene.

When the LED lighting apparatus 1 is turned on or off, the heat generated by the heat is repeatedly generated and bent toward the ceiling or the opposite side, and as time elapses, .

Therefore, it is possible to reliably prevent the phenomenon that the supporting member 90 is bent and deformed due to the heat, because it is possible to give a poor appearance.

In the case of connecting the LED lighting apparatus 1 shown in FIG. 9 to several units, the LED lighting apparatus 1 may be used as one unit so that the closing members 40 are in contact with each other.

At this time, the cut-out portion 40 formed on the closing member 40 can be removed, and the electric wire for power supply can be connected.

The closure member 40 shown in Fig. 9 can be coupled to both ends of the frame 20 and then secured to the frame 20 at the sides with a fastening member, such as a screw.

Are formed longer to form a latching space of a length difference so that both ends of the frame 20 are positioned and supported in the latching space.

A cutout 47 is formed on the front surface of the closing member 46 and a fastening hole is formed and a fastening member such as a screw is inserted into the ceiling or the like so as to be attached, ) Are formed on the substrate.

The incision 47 and the attachment piece 48 can be easily cut and removed as needed.

The cut-out portion 47 is cut and removed to allow the LED lighting device 1 to be passed through when a plurality of LED lighting devices 1 are connected to be used.

14 is an assembled cross-sectional view of the LED lighting apparatus 1 according to Fig. 12, in which a support member 90 is inserted into a space S2 formed at the lower portion of the frame 20 in the figure, The stabilizer 60 is mounted on the inner surface of the supporting member 90 and the closing member 46 is inserted into the outer surface of the frame 20. In reality, As shown in FIG.

16A to 16C are views showing a process of assembling the LED lighting apparatus 1 according to the present invention on a ceiling. FIG. 16A is a cross-sectional view of the LED lighting apparatus 1 according to the present invention, in which the mounting bracket 55 is fixed to the ceiling through a fastening member FIG. 16B shows a state immediately before the LED lighting apparatus 1 according to the present invention is inserted into the fixed mounting bracket 55, FIG. 16C shows a state where the LED lighting apparatus 1 is inserted and fixed to the mounting bracket 55, It can be easily inserted and assembled into the bracket 55 in a one-touch manner.

16B and 16C, a structure is shown in which a mounting piece is formed on a covering member formed at both ends, but such a mounting piece can be removed and used if necessary.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, But fall within the scope of the appended claims.
