  However, when the light source of the illuminating device that uses the already installed straight fluorescent lamp as the compatible light source is replaced with another light source, for example, a light source using a similar long LED or organic EL, the structure of the light source In addition, only the light source could not be easily replaced.

  Further, since the straight tube type LED lamp has a heat sink for radiating the heat generated from the LED element to the outside, the straight tube type lamp is heavier than the straight tube type fluorescent lamp, and the lamp socket for the straight tube type fluorescent lamp is used as it is. When installed, there was a problem from the viewpoint of durability and drop safety.

  In addition, when the existing lighting device is embedded in the ceiling, an opening hole is made in the ceiling according to the lighting device, and when replacing with another light source, for example, a lighting device using LED or organic EL as a light source, the ceiling hole is It is difficult to prepare the same, and it is necessary to prepare the ceiling again for a new lighting device together with the replacement of the lighting device, and there is a problem that costs are increased.

  The present invention has been made in order to solve the above-described problems, and a lighting device using a fluorescent lamp as a suitable light source is replaced with a lighting device using another light source such as an LED or an organic EL as a light source. The purpose of the present invention is to provide a highly environmentally illuminating device that reduces costs by reusing the illuminating device main body, the reflector, and the like, thereby reducing costs.

  INDUSTRIAL APPLICABILITY The present invention is used in an illuminating device including a fluorescent lamp, a ballast for lighting the fluorescent lamp, a fixture main body provided with a lamp socket, and a reflector having a through hole through which the lamp socket is inserted. In this illuminating device, instead of the fluorescent lamp, the light source has a light source different from the fluorescent lamp, and a light source unit fixed to the reflector is installed in the fixture body, and the power source is turned on by supplying power to the light source unit. The unit is installed in the instrument body, and the light source unit and the power supply unit are electrically connected by a harness through a through hole for insertion of a lamp socket that is opened in the reflector.

  According to the present invention, an existing illumination device can be used as it is, and only the light source can be replaced from a fluorescent lamp to a light source using another light source such as an LED or an organic EL. Since the fixture body of the existing lighting device is reused, for example, the ceiling hole can be used as it is even when the lighting device is an embedded fixture.

  Further, according to the present invention, the lamp socket itself is unnecessary, and the number of parts is reduced, so that the workability can be improved.

  The reflecting plate 300 has a through hole 310 for inserting a lamp socket at both ends and screw holes 320 for screwing the reflecting plate 300 to the lamp socket mounting bracket 110 of the fixture body 100. The attachment hole 330 is not a hole that has been opened since it was attached to an existing lighting fixture, but is a hole that is added by a construction worker when attaching the LED light source unit 400 to the reflector 300.

  3 is an external view of the LED light source unit, FIG. 4 is an exploded view of the LED light source unit, and FIG. 5 is a cross-sectional view of the renewal light source unit.

  As shown in FIGS. 3 and 4, the LED light source unit 400 includes an LED module 430 on which the LED element 431 is mounted, a heat sink 440 for radiating the heat generated by the LED module 430 to the outside, and the LED module 430. The LED module fixing screw 420 that is fixed to the heat sink 440 by screws, the translucent cover 410 that is attached to the heat sink 440 so as to cover the LED module 430, the L-shaped attachment piece 450, and the attachment piece 450. The mounting piece fixing screw 460 fixed by screwing to the screw fixing portion 444 of the heat sink 440, the power source harness 210 extending from the output terminal block of the power supply unit 200, and the input terminal block of the LED module 430 are directly connected to the existing lighting device. When the tube fluorescent lamp is removed, the lamp socket And a light source side harness 470 connecting through the lamp through hole 310 of the socket through the open by removing the same time.

  As shown in FIG. 5, the heat sink 440 has an H-shaped cross section, and has a mounting surface 441 to which the LED module 430 is mounted on one side and a cover mounting portion 442 to which the translucent cover 410 is mounted. ing. Further, the other side of the heat sink 440 has three radiating fins 443 on both sides facing outward, and has a screw fixing portion 444 to which a mounting piece fixing screw 460 is screwed between the two radiating fins 443. is doing. On the other side, an electric wire for connecting to the LED module 430 passes, and a space for increasing the heat dissipation effect by increasing the surface area of the heat dissipating fins 443 is formed.

  Next, an assembly procedure of the LED light source unit 400 at a manufacturing factory or the like will be described.

  A predetermined number of LED modules 430 are fixed to the mounting surface 441 of the heat sink 440 by screwing with LED module fixing screws 420. The light source side harness 470 connected to the power source side harness 210 extending from the output terminal block of the power supply unit 200 is inserted into the input terminal block of the LED module 430. The translucent cover 410 is fitted into the cover mounting portion 442 of the heat sink 440 and is slid to cover the LED module 430 with the translucent cover 410.

  Finally, two L-shaped attachment pieces 450 are brought into close contact with both ends of the LED light source unit 400 so as to cover the opening in which the light-transmitting cover 410 is fitted into the heat sink 440, and the screw insertion holes 451 and The screw fixing portion 444 of the heat sink 440 is brought into intimate contact with each other and is fixed by being screwed with an attachment piece fixing screw 460. When fixing, the light source side harness 470 connected to the input terminal block of the LED module 430 is exposed to the outside of the LED light source unit 400 through the opening 452. The assembly of the LED light source unit 400 is completed by the above procedure.

  The material of the translucent cover 410 is, for example, an acrylic resin excellent in light resistance, and milky white is desirable to soften the light of the LED element 431. In order to dissipate the heat generated from the LED module 430 to the outside, the heat sink 440 is preferably formed by extrusion of aluminum and painted in white in consideration of heat dissipation from the instrument body 100 and design. The mounting piece 450 is preferably a molded product made of resin or aluminum.

  When replacing with a lighting device having a light source of a 40W type straight tube fluorescent lamp, the total length of the light-emitting portion of the LED light source unit 400 should be shorter than the total length of the 40W type straight tube fluorescent lamp, for example, 1198 mm. . For example, 900 mm to 1100 mm is suitable.

  In the case of replacing with a lighting device having a light source of a 40 W type straight tube fluorescent lamp, it may be configured by four modules equivalent to 10 W per sheet. When replacing a lighting device having a light source of a 20 W type straight tube fluorescent lamp, generally the length of the 20 W type straight tube fluorescent lamp is about half of the length of a 40 W type straight tube fluorescent lamp. Therefore, it is better to configure with two modules. The length of one module in the longitudinal direction is preferably about 225 mm to 275 mm.

  The power supply unit is also attached to the existing lighting device as a ballast for straight tube fluorescent lamps, but the existing ballast cannot be reused when the lighting device is renewed. The existing ballast is replaced with the power supply unit 200 dedicated to the LED module. When the mounting screw can be reused, it may be used for mounting a new power supply unit 200. A power supply harness 210 is connected to the output terminal block of the power supply unit 200. If the power supply unit 200 can be attached without removing the existing ballast, the ballast itself may remain attached in order to save the trouble of removal.

  FIG. 6 is an external view of a mounting piece attached to the LED light source unit.

  In the present embodiment, as shown in FIG. 6, the attachment piece 450 is provided with a vertical portion having a shape that can completely cover the cross-sectional shape (see FIG. 5) of the translucent cover 410 attached to the heat sink 440. It is preferable to use an M4 screw mounting hole in the base plate provided with a shape such as an elongated hole 453 in consideration of the mounting pitch. Further, in the vertical portion of the mounting piece 450, there are two screw insertion holes 451 for passing the mounting piece fixing screws 460 when the LED light source unit 400 is attached to the heat sink 440, and the LED light source unit 400 and the power source side harness 210. One opening 452 for passing the light source side harness 470 to be connected is opened.

  Next, in this embodiment, a work procedure when installing the lighting device 1000 on the ceiling will be described.

  FIG. 7 is an assembly and installation procedure diagram of the illumination device, FIG. 8 is an assembly and installation procedure diagram of the illumination device, and FIG. 9 is a cross-sectional view of a screw for fixing the LED light source unit to the reflector. In FIGS. 7 and 8, some screws and wirings are not shown.

  First, an existing lighting device is removed. The procedure should be the reverse of the construction when the existing lighting device is installed. With the existing lighting device attached to the ceiling, the fluorescent lamp, the reflector 300, the wiring such as the power supply line, and the instrument body 100 are removed in this order.

  Next, the fixture body 100 removed from the ceiling is lowered to the floor, and the lamp socket and the ballast remaining without being removed from the fixture body 100 are removed. Straight tube fluorescent lamps, lamp sockets, ballasts, non-reusable wirings, screws, etc. are not used in newly installed lighting devices and may be discarded. The screw used to attach the existing lighting device is not damaged and may be reused if it can be used. Before construction, check the name of the manufacturer of the installed lighting equipment, the model name, etc., and investigate whether there are any reusable parts. So construction time can be shortened. The ballast for the straight tube fluorescent lamp may be left as it is without being removed in order to reduce the man-hours for the construction, as long as it does not hinder the installation of the power supply unit 200.

  When the removal work of the existing lighting device is finished, the mounting work of the lighting device 1000 of the present embodiment is started. If the work is performed in the reverse order of the previous removal work, the work can be carried out efficiently.

  First, the assembling work of the lighting device 1000 at a stage before installation on the ceiling is performed. As shown to Fig.7 (a), the illuminating device 1000 before a work start is in the state decomposed | disassembled into each component.

  First, as shown in FIG.7 (b), the power supply unit 200 is attached to the instrument main body 100 which has been removed and put down on the floor. The power supply unit 200 is screwed and fixed to the instrument body 100 using the existing screw holes of the instrument body 100. If the mounting holes do not fit, the construction installer adds screw holes to the instrument body 100 and attaches them. The power source harness 210 is connected to the output terminal block of the power supply unit 200 fixed to the fixture main body 100, and the fixture main body 100 is turned over and is suspended through the through hole 112 for inserting the lamp socket. It leaves outside the instrument body 100.

  Next, the appliance main body 100 lowered on the floor is re-installed on the ceiling, and wirings such as a power line and a light control line are connected.

  When the installation work of the instrument main body 100 on the ceiling is completed, the process moves to the work shown in FIG. As shown in FIG. 9, long holes 453 provided in attachment pieces 450 attached to both ends of the LED light source unit 400 are used, and the LED light source unit 400 is attached to the reflector 300 with light source unit fixing screws 481. Open and tighten. Since the reflector 300 does not have a hole subjected to burring processing or the like, it is necessary for a construction worker to directly make the attachment hole 330 in the reflector 300 and tighten the light source unit fixing screw 481.

  When the operation of attaching the LED light source unit 400 to the reflector 300 is completed, the operation moves to the operation shown in FIG. The reflector 300 to which the LED light source unit 400 is fixed is screwed into the screw hole 111 formed in the lamp socket mounting bracket 110 of the fixture main body 100 installed on the ceiling through the screw hole 320 with the reflector fixing screw 482. .

  At this time, the lamp socket insertion through hole 112 opened in the lamp socket mounting bracket 110 and the lamp socket insertion through hole 310 opened in the reflector 300 are overlapped to form one through hole. To do. Hereinafter, the through hole is referred to as a through hole 310 for inserting a lamp socket. Note that the through-hole 112 for inserting the lamp socket of the metal fitting 110 for attaching the lamp socket and the through-hole 310 for inserting the lamp socket of the reflector 300 have the same dimensions.

  After that, the light source side harness 470 extending from the LED light source unit 400 is connected to the lamp socket insertion through hole 112 opened in the lamp socket mounting bracket 110 of the fixture body 100 and the lamp socket insertion through hole 310 is overlapped. It is connected to the power supply side harness 210 that passes through and extends outside the instrument main body 100. The remainder of the harness loosened after connection and protruding from the through-hole 310 for inserting the lamp socket is pushed into the back side of the reflector 300 and covered with a seal or the like. A seal for closing the through hole 310 for inserting the lamp socket may be included as a product. In this case, two seals for the through hole 310 for inserting the lamp socket on the side through which the harness is passed and the through hole 310 for inserting the lamp socket on the side through which the harness is not passed are packaged. When all the operations are completed, the lighting apparatus 1000 is in a state as shown in FIG.

  This completes the installation work of the lighting apparatus 1000 on the ceiling.

  According to the present embodiment, the LED light source unit 400 is screwed by attaching the mounting hole 330 to the reflector 300 with the light source unit fixing screw 481, and the reflector 300 attached with the LED light source unit 400 is attached to the reflector fixing screw 482. In this case, the length of the LED light source unit 400 is shorter than that of the straight tube fluorescent lamp of the existing lighting device. However, the length of the LED light source unit 400 is limited by the position where the light source unit fixing screw 481 is screwed. As a result, there is an effect that a large number of lighting devices can be used.

  In addition, the LED light source unit 400 that replaces the straight tube fluorescent lamp of the existing lighting device and the power supply unit 200 that replaces the ballast are roughly divided into two units. In addition, the use of a through-hole from which the lamp socket of the straight tube fluorescent lamp is removed makes it possible to reduce the construction work. Conventionally, an existing lighting device can be replaced with a lighting device using a different light source such as an LED or an organic EL from a lighting device that uses a straight tube fluorescent lamp as a light source. Renewal is possible while using the main body and reflector.

  In addition, since a lamp socket is not required, for example, even when there is a lamp socket that solves problems such as weight dedicated to straight tube LED lamps, the lamp socket itself is unnecessary and the number of parts is reduced. Can be improved.

  In addition, since the degree of freedom of various dimensions and the like is high, it can be attached to products of various manufacturers. As described above, the light source and the power source are unitized, so the workability is good. From a lighting device using a straight tube fluorescent lamp as a light source in a short time, an LED or an organic EL other than a straight tube fluorescent lamp is used as a light source. Renewal of the lighting equipment that has been performed can be carried out. Therefore, since the man-hour for the ceiling work can be greatly reduced compared with completely replacing with a new lighting device, the cost can be reduced, the waste can be reduced, and the environmental effect is also effective.

Embodiment 2. FIG.
In this embodiment, a screw hole for fixing the reflector 300 of the existing lighting device is reused, and the reflector 300 is screwed into the reflector 300 together with the LED light source unit 400 with the reflector fixing screw 482. 320 is different from the first embodiment in that the elongated hole 453 of the mounting piece 450 fixed to the LED light source unit 400 and the screw hole 111 opened in the lamp socket mounting bracket 110 are overlapped and screwed. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, description thereof will be omitted, and portions different from those in the first embodiment will be described.

  Hereinafter, the present embodiment will be described with reference to FIGS.

  10 is an external view of the lighting device, FIG. 11 is an exploded view of the lighting device, and FIG. 12 is a top view and a cross-sectional view of the lighting device.

  As shown in FIGS. 10 to 12, when the LED light source unit 400 is attached to the existing lighting device, the screw holes 320 formed in the reflector 300 are reused to connect the reflector 300 and the LED light source unit 400 to the reflector. The fixing screw 482 is fastened together with the screw hole 111 formed in the lamp socket mounting bracket 110 through the existing screw hole 320 and fixed. The screw used in the existing lighting device is not damaged, and the mounting piece 450 fixed to the LED light source unit 400 is screwed together with the reflector 300 to the lamp socket mounting bracket 110 of the fixture body 100. If the length is sufficient, the screw may be reused. In addition, when screwing, since the thickness of the base of the mounting piece 450 is added in addition to the thickness of the existing reflector 300, a screw that is longer than a screw that is generally used in an existing lighting device was used. Better.

  In the present embodiment, the mounting piece 450 may have a shape as shown in FIG. 6 as in the first embodiment.

  At this time, it is necessary to match the fixing hole pitch when the LED light source unit 400 is attached to the reflecting plate 300 with the reflecting plate fixing hole pitch of the existing lighting device. In general, since there are many illumination devices with a pitch of about 1160 mm, it is preferable that the fixing holes of the LED light source unit 400 to the reflection plate 300 are like long holes 453 and can be attached at a pitch of about 1160 ± 10 mm.

  Next, in this embodiment, a work procedure when installing the lighting device 1000 on the ceiling will be described.

  Since the procedure until the apparatus main body 100 is re-installed on the ceiling, the power supply unit 200 is attached, and the wirings are connected is the same as the procedure shown in FIG.

  The LED light source unit 400 is installed on the ceiling together with the reflector 300 through the elongated holes 453 of the attachment pieces 450 fixed to both ends of the LED light source unit 400 by the reflector fixing screws 482 and the screw holes 320 of the reflector 300. The lamp socket mounting bracket 110 of the instrument main body 100 is screwed into the screw hole 111 opened.

  Since the subsequent procedure is the same as that of the first embodiment, the description thereof is omitted.

  This completes the installation work of the lighting device 1000 on the ceiling. When all the operations are completed, the lighting apparatus 1000 is in a state as shown in FIG.

  According to the present embodiment, the reflector 300 and the LED light source unit 400 are fastened together by reusing the existing screw hole 320 and the screw hole 111 with the reflector fixing screw 482, so that the elongated hole 453 of the mounting piece 450 is used. However, the LED light source unit 400 may be made longer than that in the first embodiment. However, the LED light source unit 400 may be made longer than that in the first embodiment. This has the effect of being able to do this and eliminating the need for additional parts. Moreover, it leads to the reduction of the man-hour of the installation work of the illuminating device 1000.

Embodiment 3 FIG.
The present embodiment is different from the first embodiment in that a dedicated fixture is used to fix the LED light source unit 400 to the reflector 300. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, description thereof will be omitted, and portions different from those in the first embodiment will be described.

An LED module fixing screw 420 that is fixed to the heat sink 440, a translucent cover 410 that is attached to the heat sink 440 so as to cover the LED module 430, an L-shaped attachment piece 450, and the attachment piece 450 that is attached to the heat sink 440. An attachment piece fixing screw 460 that is fixed by screwing to the screw fixing portion 444, a power source harness 210 that extends from the output terminal block of the power supply unit 200, and an input terminal block of the LED module 430 are connected to the straight fluorescent tube from the existing lighting device. When the lamp is removed, replace the lamp socket. The light source side harness 470 connected through the through-hole 310 for inserting the lamp socket opened by being removed and the U-shaped bracket fixing screw 491 are screwed together with the mounting piece 450 to fix the mounting piece 450 to the reflector 300. It is composed of a U-shaped bracket 490.

  The U-shaped metal fitting 490 has a U-shaped side surface, and includes a reflecting plate contact surface where the flat portions on both sides and inside contact the reflecting plate 300 and a U-shaped fitting fixing screw 491. It has a screw insertion surface in which a threaded hole that has been subjected to a burring process or the like for tightening is formed, and a flat surface (base) having a predetermined height that does not have holes, protrusions, or irregularities.

  When the LED light source unit 400 is attached to an existing lighting device, one side of the U-shaped bracket 490 is locked to the back side of the reflector 300 through the through hole 310 for inserting the lamp socket, and attached to the heat sink 440 of the LED light source unit 400. A mounting piece 450 screwed with a single fixing screw 460 is sandwiched between the other side of the U-shaped bracket 490 and the reflecting plate 300.

Embodiment 4 FIG.
The present embodiment is different from the third embodiment in the fixing method (the shape of the fixture) for fixing the LED light source unit 400 to the reflecting plate 300. In the present embodiment, the same components as those in the third embodiment are denoted by the same reference numerals, description thereof will be omitted, and portions different from those in the third embodiment will be described.

  Hereinafter, the present embodiment will be described with reference to FIG.

  FIG. 17 is a cross-sectional view and a perspective view of the LED light source unit installed in the lighting device.

  As shown in FIG. 17A, the LED light source unit 400 includes an LED module 430 on which the LED element 431 is mounted, a heat sink 440 for radiating heat generated by the LED module 430 to the outside, and the LED module 430. The LED module fixing screw 420 that is fixed to the heat sink 440 by screws, the translucent cover 410 that is attached to the heat sink 440 so as to cover the LED module 430, the L-shaped attachment piece 450, and the attachment piece 450. The mounting piece fixing screw 460 fixed by screwing to the screw fixing portion 444 of the heat sink 440, the power source harness 210 extending from the output terminal block of the power supply unit 200, and the input terminal block of the LED module 430 are directly connected to the existing lighting device. When the tube fluorescent lamp is removed, the lamp socket A light source side harness 470 connecting through the lamp through hole 310 of the socket through the open by removing the same time, and a LED light source unit fixing metal fitting 492 for fixing the attachment piece 450 on the reflector 300.

  The LED light source unit fixing bracket 492 has a U-shaped side surface, and has a reflection plate contact surface, an attachment piece contact surface, and a flat plate portion on both ends and inside contacting the reflection plate 300 and the attachment piece 450, and elasticity. A curved surface (base).

  In addition, the LED light source unit fixing bracket 492 has no holes, protrusions, irregularities, and the like, has a width that narrows as it approaches the tip from the base, and has a structure that opens outward to make it easier to pinch objects near the tip. . By stacking two plate-like objects to be fixed, abutting the open tip of the LED light source unit fixing bracket 492, pressing the base to the base, and sandwiching them, the target objects can be fixed. In addition, workability deteriorates because the construction worker opens the tip of the LED light source unit fixing bracket 492 immediately before the object is sandwiched, but the workability is deteriorated, but the force to suppress the object is increased, and the LED light source unit 400 is reflected. Since the LED 300 can be more stably fixed to the plate 300, the LED light source unit fixing bracket 492 may have a closed end.
