Description

[Technical Field]

[0001] The present invention relates to line lighting, and more particularly to line lighting using an LED strip bar. [Background technology]

[0002] Typically, long-length lighting is called line lighting. In the case of line lighting, the housing length is usually 2.4 meters (m).

[0003] In the case of such line lighting, the lamp is assembled into the housing and then finished with a diffuser (diffusion cover), and the lamp length is 1.2 meters to 2.4 meters. If the lamp length is longer than the maximum 2.4 meters, there is a high probability of it being damaged during transportation, and it is also impossible to move it in a building elevator.

[0004] In contrast, the maximum length of an LED line lighting lamp is 1.2 meters (M) or 2.4 meters (M), and the LED module is built into the extruded housing of the line lighting, with the extruded housing and lamp being used as an integrated unit.

[0005] However, because of the constant voltage input method, there is a portion where the DC voltage drops by the PCB pattern voltage between the current flowing to the LED module, which is the first input terminal of the DC power supply, and the current flowing to the LED module at the end, which results in a large difference in the brightness of the light source between the start and end.

[0006] In addition, since the current flowing through the LED is controlled through a resistor, power consumption is high and loss occurs through the resistor.The LED module is built into an extruded housing, which limits the movement of the product.

[0007] In addition to their electrical characteristics, conventional line lights have problems when transporting them to the site due to their length limitations, which make them prone to breakage during transport, and they are difficult to transport to upper floors due to the impossibility of using elevators within buildings. As a result, when installing them on site, several short line lights must be connected together.

[0008] When installing long line lighting, the LED converters must be installed as close as possible to the input terminals of each LED module due to voltage drop in the output wires that supply power to the LED modules. Also, since the capacity of LED converters varies depending on the LED power consumption, the LED converters may be installed in different positions, making installation difficult and causing confusion in after-sales service when a problem occurs.

[0035] According to one aspect of the present invention, the line lighting using the LED strip bar can be moved separately from the extrusion housing, so there is no risk of damaging the LED strip bar, and it can be rolled up, making it easy to move and install, thereby reducing transportation and installation costs.

[0036] In addition, the bar grooves on the LED strip bar and the bar fixing base on the extrusion housing make it easy for consumers to install and perform after-sales service (A / S; repairs, replacement, etc.).

[0037] In addition, the LED strip bar is made of silicone or PVC material, so it is resistant to shocks caused by earthquakes and vibrations. Even if the LED strip bar fixed to the extrusion housing falls off, it can prevent injury to human life because it is made of silicone or PVC material.

[0038] In addition, the LED strip bar is waterproof and can withstand moisture and water immersion during the rainy season due to the material properties of the tube.

[0039] The LED strip bar can also be inserted and fixed into an extruded housing made of silicone or PVC material to form a curved or polygonal frame.

[0040] In addition, the LED strip bar uses a constant current LED converter, which does not generate any unnecessary losses other than the power consumption for light source output, resulting in cost and energy savings. It is easy to connect to the LED converter, making it very easy to link multiple LED strip bars together. After installation, it is easy to change and install RGB or adjust the color temperature, lighting sensitivity, and brightness as desired by the consumer. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0042] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, it should be understood that the present invention is not limited to such an embodiment and can be modified in various ways.

[0043] In the drawings, in order to clearly and concisely explain the present invention, parts that are not relevant to the explanation are omitted, and the same drawing reference numerals are used throughout the specification for the same or very similar parts. In addition, in the drawings, thicknesses, widths, etc. are shown enlarged or reduced to make the explanation clearer, but the thicknesses, widths, etc. of the present invention are not limited to those shown in the drawings.

[0044] Furthermore, throughout the specification, when any part is said to "include" another part, unless otherwise specified, it does not exclude the other part and may further include the other part.

[0045] FIG. 1 is a front view showing the overall appearance of a line lighting device using an LED strip bar according to one embodiment of the present invention.

[0046] As shown in Figure 1, a line lighting system using an LED strip bar according to one embodiment of the present invention emits LED light and is resistant to vibrations and impacts during earthquakes and other vibrations due to the properties of its material. Even if the LED strip bar falls off, it prevents human casualties due to its load and material properties. It can also be waterproofed to withstand moisture and water during the rainy season due to its material properties. The system may include: (1) an LED strip bar 100 that can be rolled up for easy transportation; and (2) an extrusion housing 300 that has a textured surface and into which the LED strip bar 100 is inserted and secured. The housing can be fixed to a ceiling in one of three ways: recessed, direct-mounted, or pendant. Although not shown in the drawings, the LED strip bar 100 can be waterproofed by providing finishing caps on both ends, but the waterproofing method is not limited.

[0047] Here, the LED strip bar 100 is inserted into the extrusion housing 300, and when power is supplied, it can output light from the LED light source.Since it is made of silicone resin or PVC (polyvinyl chloride resin), it is rolled up and delivered to the site, making it easy to move.

[0048] The LED strip bar 100 can be changed to a desired color temperature, is lightweight, and is highly resistant to vibration and impact, so that even if it is dropped, it will not break and cause injury to human life.

[0049] The LED strip bar 100 can prevent damage to the LED light source caused by underground water intrusion during the rainy season, and has moisture-resistant properties when moisture occurs underground.

[0050] The LED strip bar 100 has a constant current configuration, which provides excellent light efficiency, and is energy-saving, rather than relying on resistors for current control.

[0051] The LED strip bar 100 can be directly cut to a desired length (such as 5 cm, 10 cm, or 30 cm) on site by the user at any location.

[0052] In contrast, conventional technology uses a constant voltage method, where a 24V supply is applied and constant current is controlled through a resistor. Using a constant voltage and a constant current drive circuit requires a very long cuttable length, a complex circuit, and cost structure issues. For this reason, line lighting using a constant voltage method controls current through a resistor. However, the constant voltage method results in very low light efficiency. For example, if a 10cm long, 24V constant voltage converter is used, 100mA current flows through the LEDs, and six LEDs (6EA) are connected in series, the loss is approximately 0.6W on the resistor side and 1.8W on the light source side, for a total power consumption of 2.4W. Assuming a length of 1 meter (m), an unnecessary 6W of power is lost out of the 24W power consumption. The longer the length, the greater the loss. Therefore, with longer lengths, the current flowing at the beginning of the PCB is very large, resulting in a voltage drop and a difference in light intensity (brightness) between the beginning and end. In addition, the thickness of the copper plate of the PCB pattern through which the current flows is thick, and the length is limited, which affects the deterioration of light efficiency and causes a lot of energy loss, so it is often used as a supplementary light source with a small current rather than as a main light source.

[0053] In contrast, the constant current method of the present invention uses a constant current LED converter 150 and an LED strip bar 100 configured for constant current use as a main light source. Unlike the constant voltage method, the constant current method can provide the same light source even if an 18V voltage is supplied instead of a 24V voltage. For example, if an 18V constant current converter is used at 10cm, a current of 100mA flows through the LEDs, and six LEDs (6EA) are connected in series, a total power consumption of 1.8W is generated. At 1m, the total power consumption is 18W, which is advantageous in that it does not incur unnecessary losses. Therefore, compared to the conventional linear lighting method, the present invention has a very high light efficiency and does not incur unnecessary energy losses. Furthermore, the LED strip bar 100 of the present invention uses a high voltage, resulting in low current flow, minimal PCB pattern loss, and a thinner copper plate for the PCB pattern, resulting in lower costs. Therefore, in comparison with conventional LED line lighting, in the case of constant current line lighting utilizing the LED strip bar 100 of the present invention, when an LED converter 150 having the same power consumption is used, the constant current method allows for a longer length to be used for line lighting.

[0054] The LED strip bar 100 may also include (1) LEDs 110 that emit light, (2) a light-emitting unit 120 that uniformly spreads the light source of the LEDs 110 to emit light, and (3) a tube 130 made of silicone or PVC material that encloses the LEDs 110 in a U-shape at the cross section and can be rolled up for easy transportation, and that is fixed to the extrusion housing 300.

[0055] The light emitting unit 120 may include a first light emitting surface 121 that first emits the light source light generated from the LED 110 inside the tube 130.

[0056] The second light-emitting surface 122 is formed on the outside of the tube 130 and can emit the light emitted from the first light-emitting surface 121.

[0057] The light emitting portion 120 is made of the same material as the tube 130, but has a higher transparency and is suitable for emitting light.

[0058] Next, the tube 130 may include an extrusion surface 131 formed by double extrusion with the light emitting unit 120, a sliding surface 132 formed by forming concaves and convexes on one surface of the tube 130 and abutting against the extrusion housing 300, and bar grooves (long slots like bars) 140 formed as grooves (slots) on both sides of the tube 130, into which protrusions of the extrusion housing 300 are inserted and fixed. The tube 130 may be made of, but is not limited to, a silicone resin or a PVC resin material.

[0059] The extrusion surface 131 can be formed by a double extrusion method because the tube 130 and the light emitting part 120 are made of the same material but have different degrees of transparency.

[0060] The sliding surface 132 is formed on one side of the outside of the tube 130, and by forming multiple irregularities, the tube 130, one side of which abuts against the extrusion housing 300, can be formed to slide and be easily inserted.

[0061] The sliding surface 132 and the tube 130 can dissipate heat generated by the LED 110 to the abutted extrusion housing 300 .

[0062] The bar grooves 140 are grooves (long holes) formed on both sides of the tube 130, and the protrusions on the extrusion housing 300 are inserted into the bar grooves 140 to fix the LED strip bar 100 to the extrusion housing 300.

[0063] Next, the extrusion housing 300 is used to insert and fix the LED strip bar 100 inside, and by combining the diffuser 200 on one side, it can diffuse the light emitted from the LED strip bar 100 while protecting it from the outside. The extrusion housing 300 can be installed on a ceiling using holes and fixing parts drilled in the extrusion housing 300.

[0064] In addition to aluminum, the extruded housing can also be made from PC (polycarbonate) and other synthetic resin materials.

[0065] As a result, the line lighting using the LED strip bar according to one embodiment of the present invention can be carried (moved) by separating the extrusion housing 300 and the LED strip bar 100, so there is no risk of damaging the LED strip bar 100, and the retractable LED strip bar 100 makes transportation more convenient.

[0066] Furthermore, since the LED strip bar 100 is made of silicone material, the silicone material is resistant to vibration and impact, so that the LED strip bar 100 can be fixed in place in the event of an earthquake. Even if the LED strip bar 100 fixed to the extrusion housing 300 falls off, the silicone material can prevent damage to human life.

[0067] In addition, since it is very easy to connect the LED strip bar 100 to the extrusion housing 300, even a resident who is not an ordinary technician can simply replace it with another LED strip bar 100 by pulling out and removing the bar groove 140 fixed to the protrusion of the extrusion housing 300.

[0068] In addition, the LED strip bar 100 can be adjusted to the color tone desired by the resident by replacing it with a color temperature (single color LED), a color temperature change (dual LED), or a color temperature and RGB (dual LED + RGB LED).

[0069] Hereinafter, an extruded housing of a line lighting device using an LED strip bar according to an embodiment of the present invention will be described in detail.

[0070] FIG. 2 is a front view showing an exploded view of the line lighting using the LED strip bar in FIG.

[0071] Referring to FIG. 2, the extruded housing 300 may include a housing 310 for dissipating heat from the LED strip bar 100, hooking surfaces 320 formed on both ends of the housing 310 to which the diffuser 200 is coupled, a bar fixing groove 330 formed inside the housing 310 to insert the LED strip bar 100, and a bar fixing base 340 formed inside the housing 310 to fix the LED strip bar 100 by inserting the bar groove 140.

[0072] The housing 310 may include a main body that is installed on the ceiling and a space that extends to both sides of the main body to accommodate the LED strip bar 100 .

[0073] The latching surfaces 320 are formed on the surfaces extending on both sides of the housing 310, and protrusions may be formed on some parts so that the diffuser 200 can be coupled thereto.

[0074] The diffuser 200 is attached to one side of the extrusion housing 300 and can scatter the light emitted from the LED strip bar 100 .

[0075] The bar fixing groove (slot) 330 may be formed inside the housing 310 and may be provided as a space for inserting the LED strip bar 100 into the space between the bar fixing bases 340 protruding from both sides. The LED strip bar 100 inserted into the bar fixing groove 330 may be fixed with one side abutting (butting against) the housing 310 and both side surfaces abutting against the bar fixing bases 340.

[0076] Each of the left and right bar fixing bases 340 may include a first fixing base 341 protruding from the extrusion housing 300, a second fixing base 342 bent inward from one end of the first fixing base 341 and inserted into the bar groove 140, and a third fixing base 343 bent outward from one end of the second fixing base 342 and extending diagonally to easily guide the insertion of the LED strip bar 100.

[0077] The first fixing bases 341 protrude from the inside of the housing 310 and form bar fixing grooves (slots) 330, which can fix the LED strip bar 100 by contacting both sides of the LED strip bar 100.

[0078] The second fixing blocks 342 may be bent inward from one end of the first fixing block 341 and inserted into the bar grooves 140 formed in the LED strip bar 100. In this case, the second fixing blocks 342 may be pressed into the bar grooves 140 made of silicone material, thereby being firmly fixed.

[0079] The third fixing bases 343 extend diagonally outward from one end of the second fixing bases 342, respectively, to guide the LED strip bar 100 for easy insertion. Here, since the third fixing bases 343 extend outward, residents can easily replace the LED strip bar 100.

[0080] Next, the extruded housing 300 may include mounting holes 350 that are drilled in the housing 310 and installed in a recessed or direct mounting manner during installation, mounting protrusions 360 that are formed in a protruding and recessed shape on one side of the housing 310, and mounting clips 370 that are inserted into the mounting protrusions 360 and hang and fix the extruded housing 300 so that it can be installed in a pendant manner when installed on a ceiling.

[0081] The mounting hole 350 is drilled from the inside to the outside of the housing 310 to form a hole into which the connecting port 20 described below is inserted, and additional work may be performed to ensure that the head of the connecting port 20 is fully inserted.

[0082] In addition, the mounting hole 350 forms a spaced-apart space by making a part of one outer surface of the housing 310 (in the illustrated example, the center part in the left-right direction) lower than the area of ​​one surface of the other housing, and by the force with which the connecting port 20 is fastened, the part of the outer surface is pressed against the ceiling and fastened, thereby providing a spaced-apart surface 351 for increasing the fastening force.

[0083] The mounting irregularities 360 can include a first protrusion 361 that protrudes in one direction, a first groove (long hole) 362 that forms a space below the first protrusion 361, a second groove 363 (long hole) that faces the first groove 362 and forms a space, and a second protrusion 364 that protrudes above the second groove 363 and secures the mounting clip 370 so that it does not fall off.

[0084] The first protrusion 361 protrudes into the entrance on the inside of the mounting recess 360, and the first clip 371 can be supported by the protrusion so as not to fall off.

[0085] The first groove 362 may be formed as a groove (long hole) below the first protrusion 361, forming a space into which the first clip 371 is inserted, and the protrusion protruding from the first clip 371 may be seated and fixed by the first protrusion 361 so as not to fall off.

[0086] The second groove 363 may be formed as a groove (long hole) below the second protrusion 364, forming a space into which the second clip 372 is inserted, and the protrusion protruding from the second clip 372 may be seated and fixed by the second protrusion 364 to prevent it from falling off.

[0087] The second protrusion 364 protrudes into the entrance outside the mounting recess 360, and the second clip 372 can be supported by the protrusion so as not to fall off. The size of the second protrusion 364 is formed larger than the first protrusion 361, so that the second clip 372 can be easily fixed so as not to fall off.

[0088] Next, the mounting clip 370 can include a first clip 371 that is inserted into the first groove (long hole) 362 and has a portion thereof hooked thereto, a second clip 372 that is inserted into the second groove (long hole) 363 and has a portion thereof hooked thereto so as not to come off the mounting irregularity 360, and a clip groove (long hole) 373 that is formed between the first clip 371 and the second clip 372 and has a portion thereof cut out to make it easier to insert into the mounting irregularity 360.

[0089] When the first clip 371 is inserted into the first groove 362 and the first protrusion 361, the protrusion protrudes and is hooked onto the first protrusion 361 to prevent the first clip 371 from slipping out of the first groove 362.

[0090] The second clip 372 is inserted into the second groove 363 and the second protrusion 364, and the protrusion protrudes and is hooked onto the second protrusion 364 to fix it so that it does not come out of the second groove 363. The second clip 372 is formed larger than the first clip 371, and is inserted first, and after positioning itself in the second groove 363, the first clip 371 can be inserted.

[0091] The clip groove 373 is partially cut out inside and combined with each other to facilitate the insertion process when the second clip 372 and the first clip 371 are inserted into the second groove 363 and the first groove 362, respectively, and after both the second clip 372 and the first clip 371 are inserted, the combined clip groove 373 expands again to its original state, thereby increasing the fixing force.

[0092] As a result, line lighting using an LED strip bar can be provided in three types when installed on a ceiling: an embedded type that is embedded in the ceiling, a direct-mounted type that is fixed directly to the ceiling, and a pendant type that is fixed to a wire that is fixed to the ceiling, using the mounting holes 350, mounting projections 360, and mounting clips 370 formed in the extruded housing 300.

[0093] Hereinafter, a detailed description will be given of embedded, direct-mounted, and pendant types of line lighting using an LED strip bar according to an embodiment of the present invention.

[0094] Figure 3a is a cross-sectional view showing a line lighting fixture using the LED strip bar in Figure 1 installed in an embedded type, Figure 3b is a cross-sectional view showing a line lighting fixture using the LED strip bar in Figure 1 installed in a direct-mount type, and Figure 4 is a cross-sectional view showing a line lighting fixture using the LED strip bar in Figure 1 installed in a pendant type.

[0095] Referring to Figures 3a and 3b, line lighting using an LED strip bar can be provided in either a recessed type that is embedded in the ceiling via an extruded housing 300, or a direct-mounted type that is directly fixed to the ceiling.

[0096] First, in the embedded type, the extrusion housing 300 can be embedded and fixed so that one surface of the finished ceiling and one surface of the extrusion housing 300 to which the diffuser 200 is attached are positioned on the same line.

[0097] Next, in the direct mounting type, one surface of the extrusion housing 300 is abutted against one surface of the finished ceiling and fixed, and the extrusion housing 300 can be fixed in place by protruding from the ceiling.

[0098] The recessed and direct-mounted types can be firmly fixed to the ceiling by fasteners 20 being connected to holes drilled in the extrusion housing 300.

[0099] Referring to FIG. 4, the mounting clip 370, which will be described later, is inserted into a groove formed on the top of the extruded housing 300, and the mounting clip 370 is connected to a wire installed on the ceiling, so that the extruded housing 300, which has the mounting projections 360 formed thereon, can be fixed to the ceiling in a pendant-type manner.

[0100] The mounting clip 370 is inserted from the second clip 372 into the second groove 363, and the first clip 371 is inserted into the first groove 362. During the insertion process, the clip groove 373 makes it easier to insert the second clip 372 and the first clip 371, and after the insertion is complete, the clip groove 373 returns to its original shape, increasing the fixing force.

[0101] As a result, when the extruded housing 300 is installed on the ceiling, not only can it be installed as an embedded type or a direct mounting type, but also as a pendant type line lighting, by fastening the mounting clip 370 fixed to the wire installed on the ceiling to the mounting protrusions 360 of the extruded housing 300.

[0102] Hereinafter, a process of inserting an LED strip bar into an extrusion housing formed as a circular frame for a line lighting using an LED strip bar according to an embodiment of the present invention will be described in detail.

[0103] FIG. 5 is a perspective view showing how an LED strip bar is inserted into a circular extrusion housing, and FIG. 6 is a perspective view showing how an LED strip bar is inserted into a rectangular extrusion housing.

[0104] 5 and 6, the LED strip bar 100 can be inserted into the extrusion housing 300 formed as a circular or rectangular frame, and the bar grooves 140 can be fixed to the bar fixing base 340.

[0105] First, the LED strip bar 100 is a tube 130 made of a highly flexible silicone resin material, so it can be inserted into and fixed to the extrusion housing 300 having a curved or polygonal shape.

[0106] Since the LED strip bar 100 is made of silicone resin material, it can be rolled up and transported to the site very easily. At the site, the extrusion housing 300 is installed first, and then the bar fixing base 340 formed on the extrusion housing 300 is inserted and fixed between the bar groove 140 of the LED strip bar 100, which makes the installation very easy.

[0107] Here, the LED strip bar 100 can easily withstand vibration and impact during an earthquake due to the material properties of the tube 130, and even if it falls off the bar fixing base 340 during an earthquake, the material properties of the tube 130 can prevent damage to human life.

[0108] Due to the material properties of the LED strip bar 100, it is waterproof and resistant to humidity when the basement is flooded during the rainy season.

[0109] Hereinafter, a process of continuously connecting a plurality of LED strip bars of a line lighting using an LED strip bar according to an embodiment of the present invention will be described in detail.

[0110] Figure 7 shows how multiple LED strip bars are connected to an LED converter. Figure 8 shows how multiple LED strip bars are connected to an LED converter.

[0111] 7 and 8, the LED strip bar 100 may include an LED converter 150 for connecting a plurality of LED strip bars 100 in series when installed on a ceiling.

[0112] When installing on a ceiling, in order to connect multiple LED strip bars 100 in series, an LED converter 150 with a capacity suitable for a portion of the section can be arranged to supply power.

[0113] With appropriate capacitance, the LED converter 150 can control multiple LED strip bars 100 in a long series.

[0114] The conventional technology is a line lighting that uses a constant voltage method, and has a length limitation. This is because a voltage drop occurs in the wire output from the LED converter depending on the thickness and distance of the wire, and the position of the LED converter is not uniform when installing the line lighting. In addition, the conventional technology is limited in length due to the voltage drop across the copper plate of the PCB pattern, which causes variations in the brightness of the light source, making installation difficult. In particular, the conventional technology requires a more complicated installation structure for long line lighting.

[0115] In contrast, the LED strip bar 100 of the present invention has a high voltage and low current flow type, so the wire output from the LED converter 150 is thin, and there is little voltage drop in the wire even if the wire is long. That is, the present invention has the advantage that after-sales service (A / S) and management are easy by installing the LED converter in a specific fixed box, and the LED strip bar 100 is very easy to move, store, and install when used as line lighting. For example, as shown in FIG. 7, a structure using one LED converter 150 and installing LED strip bars 100 in parallel means that, assuming one LED strip bar 100 is 10 meters long, two LED strip bars 100 can be easily installed up to a length of 20 meters or more by connecting two LED strip bars 100 in parallel to the output terminal of the LED converter 150.

[0116] In contrast, conventional lighting has the drawback of requiring a very complicated installation structure, as the lamp length is at most 2.4 meters.

[0117] 8, a structure can be shown in which one LED converter 150 is used and LED strip bars 100 are connected in series. For example, if one LED strip bar 100 is 10 meters long, the LED strip bars 100 can be connected in series to lengths of 20 meters, 30 meters, etc., by simply connecting the wires of the LED strip bars 100 once.

[0118] Next, a line lighting using an LED strip bar according to another embodiment of the present invention will be described. In the following description, only the parts that are different from the above embodiment will be described in detail, and details of the same or very similar parts will be omitted.

[0119] FIG. 9 is a front view showing the overall appearance of a line lighting device using an LED strip bar according to another embodiment of the present invention.

[0120] As shown in FIG. 9, a line lighting using an LED strip bar according to another embodiment of the present invention includes an LED strip bar 100 that emits light from an LED light source, is resistant to vibrations and impacts due to material properties during earthquakes and vibrations, prevents damage to human life due to load and material properties even if it falls off, is waterproof to withstand moisture and water in the rainy season due to material properties, and is rolled up for easy transportation; an extrusion housing 300 that has an inner surface with an uneven surface and is fixed to the ceiling in one of an embedded type, direct mounting type, or pendant type; and a separate fixing means 400 that is fixed inside the extrusion housing 300, receives the LED strip bar 100, fixes it on both sides, and dissipates heat.

[0121] First, the extruded housing 300 may include a housing 310 to which the separate fixing means 400 is fixed, hooking surfaces 320 formed on both ends of the housing 310 and to which the diffuser 200 is coupled, mounting holes 350 drilled in the housing 310 and installed in an embedded or direct mounting manner during installation, mounting protrusions and recesses 360 formed in a protruding and recessed shape on one surface of the housing 310, and mounting clips 370 inserted into the mounting protrusions and recesses 360 to hang and fix the extruded housing 300 so as to be installed in a pendant manner during installation.

[0122] The extrusion housing 300 has a space formed therein and is provided with a separate fixing means 400 for fixing therein.

[0123] The separate fixing means 400 is fixed to the extrusion housing 300, and after being fixed, the LED strip bar 100 can be inserted and fixed.

[0124] The detachable fixing means 400 may have one surface abutting against the extrusion housing 300 so as to easily dissipate heat generated by the LED strip bar 100 .

[0125] Next, a separate fixing means for a line lighting device using an LED strip bar according to another embodiment of the present invention will be described in detail.

[0126] FIG. 10 is a front view showing an exploded view of the line lighting using the LED strip bar in FIG.

[0127] Referring to FIG. 10, the detachable fixing means 400 may include a fixing body 410, a first detachable fixing base 420 extending from both sides of the fixing body 410, a second detachable fixing base 430 bent at one end of the first detachable fixing base 420 and inserted into the bar groove 140, and a third detachable fixing base 440 bent at one end of the second detachable fixing base 430 and extending diagonally downward and outward to easily guide the insertion of the LED strip bar 100.

[0128] The fixing body 410 may have one surface abutting against the extrusion housing 300 and the other surface abutting against the LED strip bar 100 .

[0129] The first separate fixing bases 420 protrude from both sides of the fixing body 410 and can abut and fix the LED strip bar 100 to both sides.

[0130] The second separate type fixing bases 430 can be bent inward at one end of the first separate type fixing bases 420 and inserted into the bar grooves 140 formed in the LED strip bar 100. At this time, the second separate type fixing bases 430 can be pressed into the bar grooves 140 made of silicone resin material and firmly fixed.

[0131] The third separate fixing bases 440 extend diagonally downward and outward from one end of the second separate fixing base 430, respectively, to guide the LED strip bar 100 for easy insertion. Here, since the third separate fixing bases 440 extend outward, residents can easily replace the LED strip bar 100.

[0132] As a result, in the line lighting using the LED strip bar according to another embodiment of the present invention, the extrusion housing 300 and the LED strip bar 100 can be moved separately, so there is no risk of the LED strip bar 100 being damaged, and the retractable LED strip bar 100 makes movement more convenient.

[0133] Furthermore, since the LED strip bar 100 is made of silicone resin material, the LED strip bar 100 made of silicone resin material, which is resistant to vibration and impact, can be fixed in place in the event of an earthquake. Even if the LED strip bar 100 fixed to the extrusion housing 300 falls off, the silicone resin material can prevent damage to human life.

[0134] In addition, since it is very easy to connect the LED strip bar 100 to the extrusion housing 300 and the detachable fixing means 400, even a resident who is not an ordinary technician can simply remove the LED strip bar 100 by pulling the bar groove 140 fixed to the detachable fixing means 400 and easily replace it with another LED strip bar 100.

[0135] In addition, the LED strip bar 100 can be adjusted to the color tone desired by the resident by replacing it with a color temperature (single color LED), a color temperature change (dual LED), or a color temperature and RGB (dual LED + RGB LED).

[0136] Although line lighting using an LED strip bar according to an embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiments presented in this specification. Those skilled in the art who understand the spirit of the present invention may easily propose other embodiments by adding, changing, deleting, or adding components within the same concept, which would also fall within the spirit of the present invention.

[0137] FIG. 11 is a perspective view showing the overall appearance of a flexible LED bar according to one embodiment of the present invention.

[0138] As shown in FIG. 11, a flexible LED bar according to one embodiment of the present invention may include an LED module 1100 that emits light, a reflector 1200 that reflects the light of the LED module 1100, a transparent body 1300 that dims the light of the LED module 1100 and the reflector 1200, and a fixing body 1400 that improves flexibility by fixing the LED module 1100 and the reflector 1200 in a diagonal direction and arranging them symmetrically facing each other.

[0139] The LED module 1100 is mounted inside the fixed body 1400 and the transparent body 1300, and can emit light when power is supplied to it. The transparent body 1300 can be made of, for example, aluminum, PC (polycarbonate), or other synthetic resin materials.

[0140] The reflector 1200 is provided inside the fixed body 1400 and the transparent body 1300, and is symmetrically arranged opposite the LED module 1100 to reflect light.

[0141] The transparent body 1300 has grooves formed therein to accommodate the LED module 1100 and the reflector 1200, and can adjust the intensity of the emitted and reflected light before it is emitted.

[0142] The fixing body 1400 can fix the LED module 1100 and the reflector 1200 in the diagonal direction and can be arranged symmetrically so as to face each other.

[0143] The fixing body 1400 may be provided with a waterproof cap 1420 having a waterproof effect to protect the LED module 1100 fixed therein.

[0144] Accordingly, the flexible LED bar according to an embodiment of the present invention has flexibility against warping and bending in the left and right directions since the LED module 1100 and the reflector 1200 are fixed to the fixing body 1400 in a diagonal direction.

[0145] Furthermore, by arranging the LED module 1100 that emits light and the reflector 1200 that reflects the light symmetrically so as to face each other, it is possible to increase the light emission efficiency.

[0146] Next, a flexible LED bar according to an embodiment of the present invention will be described in further detail.

[0147] 12a is a front view showing a detailed view of the flexible LED bar in FIG. 11, FIG. 12b is a front view showing the LED module and the reflector at the maximum angle, and FIG. 13 is an exploded view of the flexible LED bar in FIG. 12a.

[0148] 12a to 13, the transparent body 1300 may have a hollow portion 1310 for dimming light, a first groove 1320 for forming a space inside so that the LED module 1100 can be installed, and a second groove 1330 for forming a space inside so that the reflector 1200 can be installed.

[0149] First, the hollow portion 1310 is formed in the form of a hole drilled inside the transparent body 1300, and can absorb and dim light emitted and reflected from the LED module 1100 and the reflector 1200 fixed in the diagonal direction.

[0150] The hollow portion 1310 may include a first hollow surface 1311 that absorbs light from the LED module 1100, a second hollow surface 1312 that absorbs light reflected by the reflector 1200, and a lens surface 1313 that brightly dims and emits the light absorbed by the first hollow surface 1311 and the second hollow surface 1312 through a convex surface.

[0151] The first hollow surface 1311 is formed in an oblique direction so as to face the fixed LED module 1100 in the oblique direction, and can absorb the emitted light and dissipate it to the lens surface 1313.

[0152] The second hollow surface 1312 is formed diagonally symmetrically so as to face the reflector 1200 fixed in the diagonal direction, and can absorb the light reflected from the LED module 1100 and dissipate it to the lens surface 1313.

[0153] The lens surface 1313 can transmit the light absorbed from the first hollow surface 1311 and the second hollow surface 1312 and can modulate the light and emit it to the outside of the transparent body 1300 .

[0154] The lens surface 1313 shown in FIG. 13 may include a plurality of diffusing lenses 1314 so as to emit light absorbed from the first hollow surface 1311 and the second hollow surface 1312 at a brighter and more dimmed level.

[0155] Next, the fixing body 1400 may include a fixing groove 1410 formed on the outer surface, a waterproof cap 1420 that is finished at one end of the fixing body 1400 and provides a waterproof effect, a first fixing surface 1430 that is formed so that the LED module 1100 faces in the diagonal direction, and a second fixing surface 1440 that is positioned symmetrically so that the reflector 1200 faces the LED module 1100.

[0156] The fixing groove 1410 is formed on the outer surface of the fixing body 1400, and a protrusion of an external housing for fixing the flexible LED bar can be inserted and fixed.

[0157] The waterproof cap 1420 finishes the ends of the fixed body 1400 and the transparent body 1300, protects the LED module 1100 installed inside, and provides a waterproof effect to prevent water from penetrating inside even if water gets in.

[0158] The first fixing surface 1430 is formed on one surface of the fixing body 1400, and can fix the LED module 1100 in the diagonal direction and further increase the flexibility of the fixing body 1400 against warping and bending in the left and right directions.

[0159] The second fixing surface 1440 is formed on the other surface of the fixing body 1400, and fixes the reflector 1200 in the diagonal direction, and can further increase the flexibility of the fixing body 1400 against warping and bending in the left and right directions.

[0160] The first fixing surface 1430 and the second fixing surface 1440 may be inclined at an angle of 30 to 45 degrees relative to the vertical line and may face each other symmetrically.

[0161] Referring to FIG. 12b, the first fixing surface 1430 and the second fixing surface 1440 are formed in a right-angle shape, and the LED module 1100 is attached to the vertical first fixing surface 1430, and the reflector 1200 is attached to the horizontal second fixing surface 1440 to reflect light.

[0162] The third fixing surface 1450 may have one surface that abuts so that the transparent body 1300 is attached to the fixing body 1400 .

[0163] The fourth fixing surface 1460 is provided on the outer surface of the fixing body 1400, and is formed on the opposite side to the surface where the transparent body 1300 is exposed, and may have a plurality of projections and recesses.

[0164] Finally, the reflector 1200 is formed of a reflecting body 1210 and a reflecting surface 1220, and a portion of the light emitted from the LED module 1100 is reflected by the reflecting surface 1220, and the light reflected by the reflecting body 1210 fixed in the diagonal direction may be dimmed to the hollow portion 1310 or outside the transparent body 1300.

[0165] This allows the hollow portion 1310 of the transparent body 1300 to modulate the light emitted from and reflected by the LED module 1100 and the reflector 1200 and emit the light to the outside via the lens surface 1313.

[0166] Furthermore, the fixing body 1400 fixes the LED module 1100 and the reflector 1200 in an oblique direction, thereby increasing the flexibility of the flexible LED bar in the left and right directions, thereby further narrowing the bending angle.

[0167] Furthermore, if the LED module 1100 is fixed in a diagonal direction, the angle at which the light is emitted also changes to the diagonal direction, resulting in a very low light efficiency. However, the light can be reflected by the reflector 1200, which is arranged symmetrically opposite the LED module 1100, thereby increasing the light efficiency again.

[0168] Hereinafter, the flexible LED bar according to an embodiment of the present invention will be described in more detail, with the flexible LED bar being fixed to a simple housing.

[0169] FIG. 14 is a front view showing the flexible LED bar fixed to the simple housing.

[0170] Referring to FIG. 14, a fixed body 1400 can be provided with a simple housing 1470 that is fixed by a fixing groove (slot) 1410 and installed on a building.

[0171] The simple housing 1470 may include a simple protruding base 1471 protruding from one side, a simple protrusion 1472 bent at the simple protruding base 1471 to fix the fixed body 1400, and a simple support base 1473 extending from the simple protrusion 1472 to support the fixed body 1400.

[0172] In order to install the fixed body 1400 on a building, the simplified housing 1470 is first installed on the building, and then the fixed body 1400 can be inserted and fixed inside.

[0173] Next, a flexible LED bar according to another embodiment of the present invention will be described. In the following description, only the parts different from the above embodiment will be described in detail, and details of the same or very similar parts will be omitted.

[0174] FIG. 15 is a front view showing the overall appearance of a flexible LED bar according to another embodiment of the present invention.

[0175] As shown in FIG. 15, a flexible LED bar according to another embodiment of the present invention may include an LED module 1100 that emits light, an LED reflector 1500 that reflects the light of the LED module 1100 and emits the light, a transparent body 1300 that modulates the light of the LED module 1100 and the LED reflector 1500 and emits it, and a fixing body 1400 that fixes the LED module 1100 and the LED reflector 1500 in a diagonal direction and arranges them symmetrically opposite each other to improve flexibility.

[0176] Here, the LED reflector 1500 may include a main body plate 1510 fixed to the fixed body 1400, an LED 1520 provided on one side of the main body plate 1510 to emit light, and a reflective surface 1530 provided on one side of the main body plate 1510 to reflect light emitted from the LED module 1100 and the LED 1520.

[0177] The LED reflector 1500 is fixed between a second fixing surface 1440 formed on the fixing body 1400 and a second groove (slot) 1330 formed on the transparent body 1300, and can reflect light emitted from the LED module 1100 or radiate light from the LED 1520 provided therein to dim the light.

[0178] The body plate 1510 is fixed to the second fixing surface 1440 formed in the oblique direction, and can be disposed symmetrically to face the LED module 1100 .

[0179] The LED 1520 is provided on one side of the body plate 1510 and can emit light when power is supplied.

[0180] The reflective surface 1530 is formed on one surface of the body plate 1510 and can reflect both the light emitted from the LEDs 1520 and the light emitted from the LED module 1100. The reflective surface 1530 is formed on one surface of the exposed body plate 1510, excluding the surface on which the LEDs 1520 are provided, and can reflect light.

[0181] As a result, the LED reflector 1500 can dim a greater amount of light than the reflector 1200 provided in one embodiment, and can fully compensate for the reduced amount of light caused by the LED module 1100 being fixed in the diagonal direction.

[0182] Next, a line illumination using a flexible LED bar according to another embodiment of the present invention will be described. In the following description, only the differences from the above-described embodiment will be described in detail, and details of the same or very similar parts will be omitted.

[0183] FIG. 16 is a front view showing the overall appearance of a line illumination device using a flexible LED bar according to another embodiment of the present invention.

[0184] As shown in FIG. 16, a line lighting using a flexible LED bar according to another embodiment of the present invention may include an LED module 1100 that emits light, a reflector 1200 that reflects the light of the LED module 1100, a transparent body 1300 that dims the light of the LED module 1100 and the reflector 1200, a flexible LED bar having a fixing body 1400 that fixes the LED module 1100 and the reflector 1200 in a diagonal direction and arranges them symmetrically opposite each other to improve flexibility, and a housing 1600 into which the flexible LED bar is inserted and that increases the light intensity of the LED module 1100 and the reflector 1200.

[0185] Here, the housing 1600 is installed on the ceiling, wall or bottom, and a flexible LED bar can be inserted inside to dim the light.

[0186] In addition to protecting the flexible LED bar, it can also reflect the dimmed light again to increase light efficiency.

[0187] The housing 1600 may include a housing body 1610, a housing fixing base 1620 that protrudes and extends from the housing body 1610 to fix the fixing body 1400, a housing reflecting base 1630 that extends diagonally from the housing fixing base 1620 to increase the amount of light transmitted from the LED module 1100 and the reflector 1200, and a housing cover 1640 that safely protects the flexible LED bar.

[0188] The housing body 1610 can be installed on a ceiling, wall, or bottom surface to form an internal space for fixing the flexible LED bar.

[0189] The housing fixed base 1620 may include a first housing base 1621 protruding from one side, a housing protrusion 1622 bent from the first housing base 1621 to fix the fixed body 1400, and a second housing base 1623 extending from the housing protrusion 1622 to support the fixed body 1400.

[0190] The first housing base 1621 protrudes and extends from the inside of the housing body 1610 to seat the flexible LED bar.

[0191] The housing protrusion 1622 is bent at one end of the first housing base 1621 and inserted into the fixing groove 1410 formed in the fixing body 1400 to fix the flexible LED bar.

[0192] The second housing base 1623 extends from the housing protrusion 1622 and can wrap around the outer surface of the flexible LED bar to support it so that it does not fall off.

[0193] The housing reflector 1630 may include a housing extension 1631 extending diagonally from the second housing base 1623, and a housing reflecting surface 1632 formed on one side of the housing extension 1631 to increase the amount of light transmitted from the LED module 1100 and the reflector 1200.

[0194] The housing extension base 1631 extends obliquely from one end of the second housing base 1623, and the oblique directions can extend in the same line as the LED module 1100 and the reflector 1200, respectively.

[0195] The housing reflective surface 1632 reflects the light dimmed by the transparent body 1300 again, so that the light is dimmed on one side of the transparent body 1300, thereby increasing light efficiency.

[0196] This allows the housing 1600 to safely install the flexible LED bar on a ceiling, wall, or bottom surface, and allows more light to be dimmed via the housing reflector 1630, which increases the light efficiency of the light dimmed from the flexible LED bar.

[0197] Next, a line illumination using a flexible LED bar according to another embodiment of the present invention will be described. In the following description, only the differences from the above-described embodiment will be described in detail, and details of the same or very similar parts will be omitted.
