As shown in Figs. 1 to 7, an LED lighting device having a straight housing according to one embodiment of the present invention (hereinafter referred to as "LED lighting device", 100) replaces a fluorescent lamp as a light source with an LED, but in general Compatible with fluorescent lamps can be applied. At this time, the LED lighting device 100 is a straight-shaped structure having a rectangular cross section with respect to the horizontal axis direction in appearance, the actual product (for example, 22 mm × 22 mm within 25 mm corresponding cross section so that it can be used compatible with a common fluorescent lamp) X 1200 mm) is implemented.

In general, the LED lighting device 100 may be understood as the light irradiation direction of the lower side, the opposite side to the upper side, but here, for convenience of description, the light irradiation direction of the upper side, the opposite direction Defined as the lower side.

The LED lighting device 100 forms a 'H' shape having a short upper side and a long lower side, and has a housing 10 having an open type upper and lower side, and is coupled to an upper side of the housing 10 to form a first accommodating space A1. The upper cover 20 to be formed, the lower cover 30 is coupled to the lower side of the housing 10 to form a second receiving space (A2), the upper cover 20 and the lower cover 30 in the housing 10 LED panel 60 including a plurality of LEDs 61 mounted on the first and second caps 40 and 50 and the first accommodation space A1 coupled to both ends of the housing 10 in a coupled state. It is mounted in the second receiving space (A2) and includes a power supply panel 70 for supplying power to the plurality of LED (61). Here, the housing 10, the upper cover 20 and the lower cover 30 collectively referred to as "lighting case 110" (see Fig. 3).

First, the housing 10 includes a pair of vertical surfaces 10c and 10d facing each other, and a horizontal surface including an upper surface 10a and a lower surface 10b connecting the vertical surfaces to each other, based on the horizontal surface. It has a top and bottom open structure that forms an 'H' shape with a short upper side and a long lower side. In this case, the housing 10 is combined with the upper cover 20 that is detachable from the upper surface 10a to form a first accommodating space A1, and the lower cover 30 that is detachable from the lower surface 10b. ) To form a second receiving space A2. In addition, the housing 10 forms a pair of upper coupling parts 11a and 11b for sliding coupling with the upper cover 20, and a pair of lower coupling parts 12a for sliding coupling with the lower cover 30. , 12b).

The housing 10 is manufactured by extrusion molding of aluminum as a rectangular structure. At this time, the housing 10 is easy to handle when designing the reference panel and the power supply panel 70, etc. during the design of the design, easy to handle, and the assembly equipment such as auxiliary jig There is not much. On the other hand, in the case of a circular structure may be produced by extrusion molding, but the auxiliary jig is required due to the characteristics of the circular processability and assemblability is deteriorated, and the standard setting for the assembly of the LED panel 60, power supply panel 70 and Positioning is not easy

In addition, the housing 10 forms a plurality of first heat dissipation fins 10e along the longitudinal direction of the outer circumferential surface in order to sufficiently secure a contact area with air. That is, the first heat dissipation fin 10e performs a heat sink function to effectively dissipate heat generated from the LED panel 60 and the power supply panel 70.

Meanwhile, the LED panel 60 is disposed on the upper surface 10a of the housing 10, and the power supply panel 70 is disposed on the lower surface 10b. At this time, the housing 10 has a 'H' shaped upper and lower open structure, the removable structure of the upper cover 20 and the lower cover 30, thereby mounting the LED panel 60 and the power supply panel 70 therein. It has an easy shape.

In addition, since the housing 10 has an open top and bottom open structure, it has an easy structure for extrusion molding, and since the longitudinal section is rectangular, setting of a position and a reference point for extrusion molding and assembly of moving parts is easier than that of the circular structure. No jig needed. That is, the shape of the housing 10 may have advantages in terms of processability, workability, and automation compared to the circular structure.

In detail, the housing 10 mounts the LED panel 60 on the upper surface 10a of the first accommodation space A1. In this case, the housing 10 provides a structure capable of using a 'top-down' method of mounting the LED panel 60 in a vertical direction in a detached state of the upper cover 20. This is because a sufficient space for accommodating the width of the LED panel 60 is secured on the first accommodation space A1 of the housing 10. For example, when the width of the LED panel 60 is 12mm, the upper surface 10a of the first accommodating space (A1) for accommodating the LED panel 60 is 16mm and the entrance of the first accommodating space (A1) Is designed to 14 mm.

At this time, the LED panel 60 snaps to the inner protrusions 11a-1 and 11b-1 formed on the upper coupling parts 11a and 11b, respectively, in the state of being disposed on the upper surface 10a of the first accommodating space A1. It is mounted to the housing 10 using the fixing piece 68 to engage (see FIGS. 2 and 7). At this time, the fixing piece 68 is preferably manufactured using a synthetic resin that is an insulating material. In addition, the LED panel 60 is connected to the housing 10 by using a thermal tape, a thermal pad, a thermal grease, a thermal epoxy, or a plastic stopper. It can also be fixed and attached.

In addition, the housing 10 is the LED panel 60 through the 'sliding (sliding) method' to push the LED panel 60 from one side to the other side along the longitudinal direction irrespective of the opening and closing state of the upper cover 20. It is also possible to mount the structure.

In addition, the housing 10 mounts a power supply panel 70 for supplying power to a plurality of LEDs 61 included in the LED panel 60 on the lower surface 10b. At this time, since the power supply panel 70 has a structure in which the lower cover 30 is detachably attached to the housing 10 like the upper cover 20, the power supply panel 70 is fixed upside down to the lower surface 10b corresponding to the lower cover 30. Mount it. Here, since the housing 10 has a removable structure, the lower cover 30 also provides a structure in which the power supply panel 70 can be used in a top-down manner or a sliding manner similar to the LED panel 60.

Next, the upper cover 20 is a transparent material (for example, polycarbonate, acrylic, for transmitting the light emitted from the LED 61 of the LED panel 60 mounted in the first receiving space (A1) to the outside) Ashes, etc.). At this time, the upper cover 20 has a curved cross section for an even transmittance of light, and covers the LED panel 60 has a certain strength to withstand external impact.

In addition, the lower cover 30 is made of a material having good thermal conductivity (for example, aluminum material, etc.) in order to discharge heat generated from the power supply panel 70 mounted in the first accommodation space A1 to the outside. The lower cover 30 is preferably made of the same material as the housing 10. This is because the housing 10 and the lower cover 30 may be formed of an integral material, so that the heat is evenly discharged from all directions. At this time, the lower cover 30, as in the housing 10, to form a second heat radiation fin (30a) along the longitudinal direction on the outer peripheral surface for heat dissipation.

As such, the lighting case 110 forms the first accommodating space A1 along the longitudinal direction by coupling the upper cover 20 to the upper side of the housing 10, and similarly to the lower side of the lower side of the housing 10. The cover 30 is coupled to form a second accommodating space A2 along the longitudinal direction to form a straight pipe structure. Accordingly, since the lighting case 110 has a shape that is easy to mount the LED panel 60 and the power supply panel 70 therein, it may have advantages in terms of processability, workability and automation.

The first and second caps 40 and 50 are coupled to both ends of the lighting case 110, and AC power is applied from the socket of the fluorescent lamp.

First, as shown in FIGS. 4A and 4B, the first cap 40 has a first cap housing 41 that forms a coupling frame with respect to one end of the lighting case 110, and AC power is applied thereto. The first electrode terminal 42, the jumper PCB and the sensor PCB to be made of a first power panel 43 made of an integrated structure. As a result, the first power panel 43 may eliminate a separate soldering process for the terminal pin and the PCB.

In particular, the first power panel 43 has a jumper PCB function for connection with the first electrode terminal 42 on one side, and a sensor PCB function for connection of the illumination sensor 44 and the variable resistance controller 45 on the other side. Implementation on a single panel (see FIGS. 4A and 4B).

The first power panel 43 has an illuminance sensor 44 for sensing the illuminance of the installation area of the LED lighting device 100 and a variable resistance adjusting unit 45 for adjusting the illuminance of the LED 61 on the other side. Connected. Here, the illuminance sensor 44 generates an illuminance signal to automatically switch the plurality of LEDs 61 according to the illuminance sensing result in the power control unit (not shown) of the power supply panel 70. For example, according to the illuminance sensing result of the illuminance sensor 44, the power control unit (not shown) turns on the LED 61 when the illuminance for the installation area of the LED lighting device 100 becomes dark. In addition, the variable resistance controller 45 adjusts the illuminance of the LED 61 turned on according to the resistance value of the variable resistor preset by the user. That is, the user may set the variable resistance adjusting unit 45 to adjust the illuminance of the LED lighting device 100 to the desired brightness.

The illuminance sensor 44 and the variable resistance adjusting unit 45 need to be exposed to the outside even when assembled and mounted inside the first cap housing 41. That is, the illuminance sensor 44 is exposed to the outside to sense the external illuminance, and the variable resistance adjusting unit 45 should be able to set the resistance value of the variable resistor by the user as needed.

Accordingly, the first cap housing 41 forms a hole 41a on the outer circumferential surface for exposing the illumination sensor 44 and the variable resistance adjusting unit 45 coupled to the first power panel 43 to the outside. At this time, the first cap housing 41 has a housing cap 46 that covers the hole 41a and is detachable by the user. Here, the housing cap 46 has a strength that can protect the roughness sensor 44 and the variable resistance control unit 45 to some extent, and a polycarbonate material of a transparent material through which light from the outside can pass. It may be made of.

In addition, the first power panel 43 is connected to the first connector 47a connected to the LED panel 60 and the second connector 47b connected to the power supply panel 70 on the other side, respectively. At this time, the first and second connectors 47a and 47b are connected to each other to form AC and DC power paths between the LED panel 60 and the power supply panel 70 (see FIG. 4C). That is, the first connector 47a applies the AC power applied from the second cap 50 through the LED panel 60 to the second connector 47b and through the power supply panel 70, the second connector ( (+) And (-) DC power applied from 47b) is applied to the LED panel 60. In addition, the second connector 47b applies the AC power applied from the first power supply terminal 42 and the first connector 47a to the power supply panel 70, and is applied from the power supply panel 70. ) And (-) DC power to the LED panel 60.

Here, each of the first and second connectors 47a and 47b is formed of any one of a female connector and a male connector, and thus corresponding connectors of the LED panel 60 and the power supply panel 70 are formed.

Next, the second cap 50 has a second cap housing 51 forming a coupling frame for the other end of the lighting case 110, the second electrode terminal 52 to which AC power is applied, It consists of a second power panel 53 for applying the AC power applied from the second electrode terminal 52 to the LED panel 60. In this case, a separate connector and lead wire (not shown) are formed on the second power panel 53 to apply AC power to the LED panel 60.

Hereinafter, the LED panel 60 will be described in detail.

First, the LED panel 60 is electrically connected to the power supply panel 70, and supplies power to the plurality of LEDs 61. At this time, the plurality of LEDs 61 are electrically connected to the (+) and (-) DC power lines (65,66) to emit light stably.

The LED panel 60 forms an LED bonding pad 63 for mounting a plurality of LEDs 61 using the LED PCB 62 as a lower substrate (see FIG. 5). Here, the LED panel 60 is a linear AC power line 64 is patterned in order to apply the AC power input from the second electrode terminal 51 of the second cap 50 to the power supply panel 70. In order to supply DC power input from the power supply panel 70 to the plurality of LEDs 61, positive and negative DC power lines 65 and 66 are patterned. In particular, the (+) DC power supply line 65 is separated for each site where the LED 61 is mounted in series, and the (-) DC power supply line 66 has a linear pattern.

In addition, a portion of the LED 61 is in contact between the AC power line 64 and the (+) DC power line 65, a plurality of heat dissipation patterns 67 for conducting / dissipating heat generated from the LED 61. ) Is formed intermittently. Here, the (+) DC power line 65 and the heat dissipation pattern 67 forms an LED bonding pad 63 corresponding to the size of the LED 61 and not coated with an insulating film for mounting the LED 61. . At this time, the (+) DC power supply line 65 forms an end facing the separation so that the LED 61 can be arranged in series at the point where the LED bonding pad 63 is formed.

The LED panel 60 is a state in which the AC power line 64 and the (+) and (-) DC power line (65,66) is patterned, a plurality of LEDs 61 is mounted on the LED bonding pad 69 Insulation coding is performed to increase the breakdown voltage.

On the other hand, since the LED lighting device 100 of the present invention uses the housing 10 is limited to approximately 22mm in width in order to use the existing fluorescent lamps, correspondingly the first receiving space (A1) of the housing 10 The width L0 of the LED panel 60 to be mounted on is set.

In fact, since the LED panel 60 is coupled to the top surface 10a of the first accommodation space A1 in a top-down manner, the LED panel 60 should be implemented within 14 mm of the width of the top surface 10a. Accordingly, the case where the width L0 of the LED panel 60 is set to within about 12 mm will be described. In this case, the distance L2 between the AC power line 64 and the (-) DC power line 66 is ensured to be within 6 mm, and between the AC power line 64 and the edge (side) of the LED panel 60. The distance L1 and the distance L3 between the negative (-) DC power line 66 and the edge (side) of the LED panel 60 are respectively secured to 3 mm. As a result, the LED panel 60 may be embodied in a width L0 within 12 mm, and may be detachably attached to the upper surface 10a of the first accommodating space A1 in a top-down manner.

As described above, the LED panel 60 is manufactured by reflecting the distance between each power line and the distance between the power line and the edge of the LED panel 60, thereby guaranteeing the connection of the non-insulated power supply panel 70. Insulation should be provided by securing 3k insulation voltage. In particular, the LED panel 60 can ensure an insulation breakdown voltage of 3.5 kV or more when the following insulation coating is applied.

First, in the case of a parylene coating (parylene coating), the front of the LED panel 60 is a parallel coating. The paraline coating is coated with a uniform thickness up to the edge of the lens with the curvature of the LED 61. The paraline coating is dried for 4-6 hours after the paraline addition. After the parallel coating was completed, the insulation breakdown voltage was measured to measure 3.5∼4.0㎸.

Next, in the case of spray coating, spray coating is performed using a liquid polymer on the front surface of the LED panel 60. Spray coating is performed on the front surface of the LED panel 60 and dried at 90 ° C for 10 minutes. After the spray coating was completed, the insulation breakdown voltage was measured to measure 3.5 kV to 4.0 kV.

Finally, in the case of silicon coating (silicon coating), molded in silicon, dried at room temperature and heat-treated at 90 ℃ 10 minutes. After the silicon coating was completed, the insulation breakdown voltage was measured, and 3.5 ㎸ was measured.

As described above, the LED panel 60 ensures an insulation withstand voltage of 3.5 kV or more when an additional insulation coating is made, so that the LED panel 60 is connected to a non-insulated power supply panel 70 using 220V AC power. It satisfies the 3 kV breakdown voltage requirement of the standard).

Hereinafter, the power supply panel 70 will be described in detail.

First, the power supply panel 70 includes a conversion circuit element 71 including an AC / DC conversion circuit for converting AC power to DC power. Here, the conversion circuit element 71 is implemented by combining passive elements such as resistors and capacitors and active elements such as transistors and ICs, and converting AC / DC using the same. The detailed description is omitted as it will be easily understood by those skilled in the art.

The power supply panel 70 receives AC power directly or indirectly from the first and second electrode terminals 41 and 51 and converts the AC power into DC power to supply the (+) and (-) DC power lines of the LED panel 60. (65,66). In this case, the power supply panel 70 is connected to the second connector 47b of the first power panel 43 to receive AC power and provide DC power to the LED panel 60.

In particular, the power supply panel 70 is directly connected to the first electrode terminal 41 when the AC power is applied from the first electrode terminal 41 of the first cap 40, so that the AC power is immediately input. When AC power is applied from the second electrode terminal 51 of the second cap 50, the AC power is input via the AC power line 64 patterned on the LED panel 60.

The power supply panel 70 mounts the conversion circuit element 71 on the panel through soldering and is attached to the lower surface 10b of the second accommodation space A2 in the housing 10. Insulating substrate 72 (eg, plastic substrate, FR4 substrate, etc.) is press-bonded to the soldering surface to provide insulation.

In addition, after the conversion circuit element 71 and the insulating substrate 72 are mounted, the power supply panel 70 may have an overall insulating coating to improve electrical insulation and prevent degradation of the insulation caused by moisture or moisture. insulation coating (for example, acrylic insulation coating, polyurethane insulation coating, silicon insulation coating, etc.) may be performed.

However, the power supply panel 70 is different from the method of insulating using the insulating substrate 72 and the insulating coating, as described above, after mounting the conversion circuit element 71 on the panel and the contraction tube (contraction tube) It can also be insulated using. As described above, in the case of insulating by using a shrink tube, heat dissipation characteristics are inferior to the method of applying the insulating substrate 72 and the insulating coating as a structure in which heat generated in the conversion circuit element 71 is hard to be discharged to the outside. . That is, when using a shrink tube, it was confirmed that it exhibits a temperature of about 8 degreeC or more. Accordingly, when the power supply panel 70 is attached and assembled to the lower surface 10b of the second accommodation space A2 in the housing 10, the power supply panel 70 may form the left and right side surfaces 10c and 10d of the second accommodation space A2. Through the thermal pads 73 for releasing the heat generated from the conversion circuit element 71 are assembled together (see Fig. 6). In this case, the thermal pad 73 may be separated from the housing 10 when the thermal pad 73 is assembled to the power supply panel 70, and thus corresponds to the conversion circuit element 71 of the power supply panel 70. It can be assembled simply by top-down coupling to points.

The thermal pad 73 accommodates the conversion circuit element 71 and contacts the left and right side surfaces 10c and 10d or the lower cover 30 of the second accommodation space A2 from the conversion circuit element 71. The generated heat is discharged through the left and right sides 10c and 10d and the lower cover 30 of the second accommodation space A2. In one example, the thermal pad 73 is implemented in a tunnel type that encloses and converts the conversion circuit element 71 to absorb and radiate heat generated through the front surface of the conversion circuit element 71 to the outside (see FIG. 7). .
