Description

Flat edge lighting with indirect lighting decoration}

The present invention relates to a flat edge lighting using an LED light source and a light guide plate. More specifically, the present invention relates to a flat edge lighting lamp using an LED light source body and a light guide plate. More specifically, by improving the frame structure of the lighting lamp, the light guide plate and the light source can be stably installed and fixed, as well as in the side and lower direction through the improved frame. This is about a flat edge lighting that can create a luxurious appearance along with beautiful decoration using indirect lighting.

In general, the Light Guide Plate is a part that performs the brightness and uniform lighting function of the backlight unit (BLU). It refers to an acrylic injection molded material assembled inside the BLU that guides light to the liquid crystal within a liquid crystal display (LCD). It is a plastic molded lens that plays the role of uniformly transmitting light emitted from a cold cathode fluorescent lamp (CCFL) to the entire surface of the LCD.

Meanwhile, LED, a light source using the luminescence phenomenon of injection-type electroluminescence that emits light with electric current, has the advantage of good light resistance and thousands of colors, so it is widely used in outdoor architectural lighting.

Accordingly, lighting using an LED light source and a light guide plate has various forms. One of these forms is a flat plate in which the light source is placed on the border of a square light and the light guide plate is arranged to emit light in the inner side direction of the light source. Edge lighting is gaining popularity.

In this type of flat edge lighting, the light source is connected to a rectangular circuit board inserted into the extruded frame, and the extruded frame has various lengths and various cross-sectional shapes, and has an LED light source therein as described above. A space is formed to accommodate an LED module made of a plate, etc.

Next, the extrusion frame is produced continuously by extrusion using a material that has excellent heat dissipation, excellent formability, and is lightweight, such as aluminum. After cutting the extrusion frame to a certain length, the cut extrusion frame is placed in an orthogonal direction. The basic structure of a typical flat edge lighting is to complete a square-shaped lighting frame on a plane by firmly joining and fixing the ends of each extruded frame through separately provided corner connectors in the arranged state.

This type of flat edge lighting, as shown in Registered Patent No. 10-1575584, has a 'ㄷ' shaped fitting part into which a floodlight plate is inserted on one side, and a PCB with an LED that irradiates light to the side of the floodlight plate is inserted. A plurality of frame frames are provided so that the insertion hole communicates with the fitting part, and a plurality of corner connectors are joined between the frame frames to form a square-shaped flat lighting fixture, and the locking protrusions are provided on both sides of the corner connectors. The coupling protrusion is formed elastically, and the frame frame is formed with a connector coupling part having a coupling hole into which the coupling protrusion is inserted, and a protrusion hole into which the locking protrusion is inserted is formed on the coupling part to form a corner connector in a one-touch coupling method. This improves assembling, and also forms a wire insertion part on the back of the frame where the wires connected to the PCB can be buried, so the wires can be assembled so that they are not visible, and the light emitted from the light emitting plate is blocked. By attaching the glare panel, which reflects to the rear of the luminaire, to the upper side of the frame in a detachable manner, the frame is not visible to the outside, which not only improves the aesthetics of the luminaire, but also provides light metering to prevent dark areas of the luminaire from appearing. An edge flat type LED lighting fixture using this technology has been developed and registered.

In addition, as shown in Registered Patent No. 10-1590489, the electromagnetic wave blocking effect is excellent, the efficiency of light emitted through the light guide plate is close to 100%, the fastening method is a slide method, and the four corner parts are made of plastic molded products. Not only does it prevent electric shock, but a separate bracket is provided at the back corner to prevent bending of the entire lighting fixture. An edge-type LED embedded lighting fixture consisting of a combination of diffuser plate/light guide plate/reflective sheet has been developed and registered. there is.

Next, as shown in Registered Patent No. 10-1752463, the light guide plate installed at the edge of the LED lighting interacts with the auxiliary reflective sheet and the reflective sheet to double the diffusion effect of the LED light source without light attenuation. An LED lighting lamp with a light guide plate structure has been developed and registered.

In addition, as shown in Patent No. 10-1854619, there are four edge frames assembled in a square shape to sequentially accommodate a light diffusion plate, a light guide plate, a reflector, and a heat sink from the bottom, and at least one edge frame among the edge frames. In the edge LED planar light-emitting lighting device including an installed strip-shaped LED substrate, the edge frame and the heat sink are molded from aluminum, each edge frame is assembled by a corner connector molded from an insulating material, and the LED substrate is An edge that surrounds the entire LED substrate and is accommodated in an insulating channel with an opening formed only in the direction of LED light transmission and installed in the edge frame, and the light guide plate is in close contact with the insulating channel within the edge frame to close the opening of the insulating channel. An LED surface-emitting lighting device has been developed and registered.

However, various existing flat edge lighting lamps have an extremely simple structure and shape consisting of a light guide plate and light source arranged within a rectangular frame, and while they have a simple and closely installed appearance in the construction state, they produce an overly monotonous aesthetic. Not only is the decorative effect of lighting using ceiling lights not being demonstrated at all, but it also has the problem of not matching the interior at all.

In addition, a side auxiliary light source is applied to some existing flat edge lights to create auxiliary lighting in the side or downward direction of the lights, thereby improving the decorativeness of the flat edge lights when lit. , Flat edge lighting with this structure causes the auxiliary light source to be exposed or visible to the outside, which acts as a factor that spoils the appearance of the lighting when the light source is turned on or not turned on, and is essential for accommodating the side auxiliary light source. Because the components are excessive and require a lot of space, they have the disadvantage of damaging the original purpose of flat edge lighting, which pursues simplicity and slimness. In addition, as assembly and productivity are significantly reduced, the economic effect is also extremely unreasonable. There is a problem.
