Description

  The present invention relates to an LED lighting device, and more particularly to an LED lighting device that can be directly attached to an existing straight tube fluorescent lamp.

  In recent years, LED lamps are rapidly spreading in place of fluorescent lamps. LED lamps have the advantages of lower power consumption and longer life than fluorescent lamps. In addition, when the LED lamp is mounted, it is possible to use an existing fluorescent lamp as it is, and it is possible to install the LED lamp as an LED lighting device by simply replacing the lamp from the fluorescent lamp to the LED lamp. For example, Patent Document 1 discloses a fluorescent lamp type LED lighting fixture that is set to a specified length corresponding to the wattage of a fluorescent tube, and that can be easily attached to an existing fluorescent lamp fixture after removing the fluorescent tube. (See Patent Document 1). Such fluorescent lamp replacement type LED lighting fixtures can be installed with relatively simple construction, and the installation cost is low, and the atmosphere of the room when using fluorescent lamps up to that time can be maintained. There is an advantage that you can.

JP 2001-351402 A

  By the way, the fluorescent lamp is generally provided with a ballast for controlling the lamp current value and supplying a starting voltage necessary for lighting the lamp and an appropriate preheating voltage to the electrodes. For example, in the case of a rapid start type fluorescent lamp, the lamp is lit by a combination of a rapid start type lamp having a starting auxiliary conductor and a rapid ballast which is a kind of electromagnetic ballast having a preheating winding. ing. In the case of an inverter type fluorescent lamp, the lamp is lit by an inverter circuit using an electronic ballast for high frequency lighting.

  However, since the conventional fluorescent lamp type LED lighting fixture simply replaces the fluorescent lamp with the LED lamp, and is used by electrically connecting the LED lamp to the conventional fluorescent lamp fixture, The ballast provided in the above is used as it is for lighting operation and the like. For this reason, there is a possibility of causing a fire accident or the like due to the ballast provided in the LED lighting device itself and the ballast of the fluorescent lamp lamp acting in a superimposed manner. As a result, the Electrical Appliance and Material Safety Law (so-called PSE method) It was also difficult to clear the technical standards based on). In addition to the safety problem, the fluorescent lamp ballast itself consumes about 7-11 W of electric power, and thus there is a problem of wasteful power consumption.

  In order to avoid such a safety problem and a problem of wasted power consumption, a method of removing a ballast provided in a fluorescent lamp device may be used when replacing a fluorescent lamp with an LED lamp. However, this method has a problem in that it requires labor and cost for construction, and cannot be easily performed particularly in ordinary households. These problems reduce the advantages of the LED lighting fixtures that can be installed with relatively simple construction and are low in installation cost, and that are less expensive. It may be a hindrance to the spread of

  Therefore, the problems to be solved by the present invention can avoid the problem of safety and the waste of power consumption, and are also installed with relatively simple construction even when replacing the fluorescent lamp with the LED lighting fixture. It is possible to provide an LED lighting apparatus that can maintain the advantages of being able to maintain the atmosphere of the room when the fluorescent lamp is used, and can be installed at low cost.

  In order to solve the above problems, the first invention has a straight tube fluorescent lamp shape, and is provided with an LED lamp part in which a plurality of LED elements are arranged, and both ends of the LED lamp part. Provided is an LED lighting apparatus having a pair of end cap portions with support pins that can be attached to a socket of a lamp and do not perform an electrical function.

  Moreover, 2nd invention provides the LED lighting fixture which further has the detachable support pin cover which covers a support pin of the said end cap part and protects a support pin based on 1st invention.

  Further, the third invention is based on the first or second invention, and connects itself to the straight tube fluorescent lamp to prevent the falling when the support pin is not supported by the straight tube fluorescent lamp. An LED luminaire further comprising a connecting string for the purpose.

  According to the present invention, safety problems and wasteful power consumption can be avoided, and it is possible to install with relatively simple construction even when replacing a fluorescent lamp with an LED lighting fixture, and the installation cost is also reduced. In addition to being inexpensive, it is possible to provide an LED luminaire that can maintain the advantages of being able to maintain the atmosphere of the room when the fluorescent lamp is used.

The first embodiment mainly relates to claim 1 and the like, the second embodiment mainly relates to claim 2 and the like, and the third embodiment mainly relates to claim 3 and the like. In addition, this invention is not limited to this Example at all, and can be implemented in various modes without departing from the gist thereof.

  <Overview>

  The LED lighting apparatus of the present embodiment has a straight tube fluorescent lamp shape, and is provided with an LED lamp unit in which a plurality of LED elements are arranged, and both ends of the LED lamp unit, and is provided in a socket of a straight tube type fluorescent lamp device. And a pair of end cap portions having support pins that can be attached and do not perform an electrical function. For this reason, it can be used as an independent instrument simply by receiving power supply from the power source, or it can be used by attaching it to a socket of an existing straight tube fluorescent lamp. Even in the latter case, since the support pin for mounting on the socket does not perform an electrical function and is merely for holding the LED lighting apparatus, a fluorescent lamp stabilizer is provided in the LED lighting apparatus itself. It does not act in a superimposed manner with the existing ballast and safety problems can be avoided.

  <Configuration>

    (General lighting equipment)

  FIG. 1 is a perspective view showing an example of the shape of the LED lighting apparatus of the present embodiment. As shown in the figure, the LED lighting apparatus 0100 according to the present embodiment includes an LED lamp part 0110 and a pair of end cap parts 0120a and 0120b.

    (LED lamp part)

        (General)

  The LED lamp portion has a straight tube fluorescent lamp shape, and a plurality of LED elements are arranged.

  The specific configuration of the LED lamp unit is the same as that of a known straight tube fluorescent lamp-shaped LED lamp. For example, a cylindrical tube body 0111 made of transparent or translucent plastic is inserted from an external power source through a circuit board. A plurality of LED elements that are supplied with power and emit light are arranged in an array on the circuit board. For example, a cylindrical tube may be a single material, and in this case, it may be integrally formed by injection molding. Alternatively, for example, different materials may be combined such that the upper half is made of metal such as aluminum and the lower half is made of plastic such as polycarbonate. FIG. 1 shows this example, and the tube body 0111 is a combination of a metal upper half body 0112 and a plastic lower half body 0113. In the case of this example, by using a metal material for the upper half, the strength of the tube is increased and the illumination efficiency when the light emitted from the LED element is reflected downward (in the floor surface of the room) is increased. In addition, by bringing the metal part into contact with the circuit board, heat generated with light emission can be conducted from the circuit board to the metal part, and the heat dissipation effect can be enhanced.

  As with conventional LED lighting fixtures, the LED lighting fixture of the present invention includes a ballast, an AC / DC converter (rectifier), a capacitor, and the like. The arrangement location may be appropriately designed. For example, it is arranged in the housing of the socket part or the inside of the tube body constituting the LED lamp part (for example, the upper half body shown in FIG. 1).

  With such a configuration, the LED lighting apparatus of the present invention has a function as an independent apparatus, and as long as power is supplied from a power source, the LED lighting apparatus can perform an illumination function without requiring any additional member. be able to. As a means for receiving power supply from the power source, as shown in FIG. 1, it is sufficient to simply provide a power line 0130 connected to the LED circuit board by partially exposing the LED lighting fixture to the outside. Is connected to the power line from the power source, the power from the power source is supplied to the LED circuit board and further to the LED element through these power lines, and the LED element can be illuminated.

        (Example of LED element arrangement)

  The LED element is a semiconductor element that emits light when an electric current is passed, and a plurality of LED elements are arranged on the circuit board of the LED lamp unit. Although there is no limitation in the arrangement method, they are usually arranged in an array in the straight pipe axis direction.

  FIG. 2 is a perspective view showing an example of the arrangement of the LED elements in the LED lamp portion of the LED lighting apparatus of the present embodiment. FIG. 2B shows an arrangement example similar to a typical example of how LED elements are arranged in a conventional LED lamp. In the example of this figure, a plurality of LED elements 0214 in the LED lamp portion (only one LED element is given a sign to avoid complication) are arranged in an array in the straight tube axis direction on the circuit board 0215. It has been. Here, the “straight tube axial direction” refers to the direction indicated by the arrow AA ′ in the drawing, that is, the longitudinal direction of the straight tube lamp.

  Fig.2 (a) shows an example of another arrangement | positioning of the LED element of the LED lamp part of the LED lighting fixture of a present Example. In the example of this figure, the LED elements of the LED lamp portion are arranged in the straight tube axis direction, and are arranged obliquely so that adjacent LED elements overlap in a direction perpendicular to the straight tube axis. That is, in this example, unlike the conventional LED lamp, the LED elements adjacent to each other in the direction perpendicular to the straight tube axis are arranged obliquely. Speaking in line with FIG. 2A, the “direction perpendicular to the straight tube axis” is a direction indicated by an arrow BB ′ in the figure, and in this direction “an oblique direction so that adjacent LED elements overlap each other”. ”Arranged” means that the width of one LED element (in this figure, LED element 0214a) occupies left and right on the line indicating this direction (on the vertical line in this figure) (L1 in this figure). Part of the width occupied by the left and right LED elements (LED element 0214b in this figure) (width shown by L2 in this figure) is partially overlapped (width shown by L3 in this figure). Therefore, the orientation of the individual LED elements is arranged obliquely with respect to the straight pipe axis. In this respect, as shown in FIG. 2B, the arrangement of the conventional LED elements does not overlap on the vertical line, which is different from the arrangement of the LED elements in the direction parallel to the straight tube axis. .

  The LED elements of the LED lamp portion of this embodiment may be arranged as shown in FIG. The purpose of such an arrangement is to maintain the atmosphere of the room at the time of the fluorescent lamp so as not to change when it is used by being attached to an existing straight tube fluorescent lamp. . In this regard, in the conventional arrangement of the LED elements as shown in FIG. 2 (b), when at least the lower part of the tube is made of transparent plastic, the LED elements are spaced apart from each other. It seems that the elements are lined up in dots, and a sense of incongruity occurs compared to the conventional fluorescent lamp. If the lower part of the tube is made of translucent plastic, such a sense of incongruity can be eliminated. However, in order to increase the illumination efficiency, the lower part of the tube is preferably transparent.

  Therefore, with the arrangement as shown in FIG. 2 (a), even if the lower part of the tube is made of transparent plastic, all the LED elements are connected and shine with the naked eye. Since it can be seen, there is no sense of incongruity compared to the conventional fluorescent lamp, and the atmosphere of the room when using the fluorescent lamp can be maintained so as not to change. Therefore, it is not necessary that the LED elements are arranged in contact with each other, but it is necessary that the LED elements are arranged at a narrow interval so that all the LED elements appear to shine with the naked eye.

  2A shows an example in which the planar shape of each LED element is a substantially rectangular shape, the shape of the LED element is not limited to such a shape. The approximate polygon may be used. The specific meaning of “disposed diagonally so that LED elements adjacent in the direction perpendicular to the straight tube axis overlap” in these cases may be considered in the same manner as in the case of the substantially rectangular shape, for example, When the planar shape of the LED elements is substantially elliptical, it means that the widths of the adjacent LED elements occupying the left and right partly overlap, and the major axis and minor axis directions are inclined obliquely. .

        (Power supply route)

  As described above, in the LED lighting apparatus of the present invention, the electric power input from the power source is directly supplied to the circuit board without going through the ballast of the fluorescent lamp, and a plurality of the electric lamps arranged on the circuit board are further provided. The LED elements are supplied to cause the LED elements to emit light. Here, the power supply path in the present invention will be described again in comparison with the power supply path in the conventional fluorescent lamp type LED lighting apparatus.

  FIG. 3 is a conceptual diagram illustrating an example of a power supply path in the LED lighting apparatus. Among these, Fig.3 (a) shows the electric power supply path | route in the LED lighting fixture of this invention, FIG.3 (b) shows the electric power supply path | route in the conventional fluorescent lamp type LED lighting fixture.

  As shown in FIG. 3B, in the conventional apparatus, the LED lamp 0310 is electrically connected to the socket 0370 of the fluorescent lamp. For this reason, the electric power introduced from the primary power supply 0300 passes through a ballast (shown as a fluorescent lamp fixture ballast 0380 in the figure) provided in the fluorescent lamp device, and also includes a ballast, AC / It is supplied to the LED circuit board 0391 of the LED lamp via a DC converter, a capacitor, etc. (abbreviated as AC / DC converter 0390 in the figure) (In this figure, power is supplied from a primary power source which is a typical example) As shown in the example, the same applies when supplying from a battery or the like). For this reason, as described above, the ballast, AC / DC converter, condenser, etc. provided in the LED lamp itself and the ballast of the fluorescent lamp fixture may act in a superimposed manner, which may cause a fire accident or the like. It is.

  On the other hand, in the apparatus of the present invention shown in FIG. 3 (a), what is shown as the LED lamp 0310 corresponds to the LED lighting apparatus of the present invention and is an independent apparatus. Therefore, a function as a lighting fixture can be achieved only by receiving power supply from the primary power supply 0300 (that is, what is referred to as an “LED lamp” in this paragraph and the next paragraph is synonymous with “LED lighting fixture”). . In this figure, the fluorescent lamp socket 0370 and the fluorescent lamp stabilizer 0380 are drawn assuming that the LED lamp is attached to an existing fluorescent lamp, but the LED lamp is electrically connected to these. There is nothing. Therefore, in the case of showing a figure in the case where the LED lamp is used as an independent instrument, the fluorescent lamp lamp socket and the fluorescent lamp stabilizer need only be excluded from the figure.

  Even when the LED lamp is attached to the socket of the fluorescent lamp as shown in the example of this figure, the socket of the fluorescent lamp is simply used as a support for preventing the LED lamp from dropping. Absent. For this reason, the power introduced from the primary power supply 0300 through, for example, the connector 0330 (in this figure, the case where a power supply connector and a main body side connector to be described later are used is displayed as a combined concept) The LED lamp is directly supplied to the LED circuit board 0391 of the LED lamp via the AC / DC converter 0390 provided in the LED lamp itself without going through the ballast 0380 provided in the lamp. For this reason, it is possible to avoid the possibility of causing a fire accident or the like due to the ballast, AC / DC converter, condenser, and the like provided in the LED lamp itself and the ballast of the fluorescent lamp fixture acting in a superimposed manner. This is exactly the same even when the LED lamp is used as an independent instrument without being attached to an existing fluorescent lamp.

  In addition, as a method of connecting the power line from the external power source and the power line provided on the LED lighting apparatus side, for example, both power lines may be simply twisted, but a plug is attached to the tip of the power line provided on the LED lighting apparatus side. This may be connected by plugging it into an outlet provided at the tip of a power line provided on the external power supply side. Or you may utilize the main-body connector part provided in the power connector and LED lighting fixture side connected to the power line from a power supply. The last configuration will be described later.

        (How to use as an instrument)

  As described above, the LED lighting device of the present invention has a function as an independent device, and as long as it receives power supply from a power source, it exhibits a lighting function without the need for other auxiliary members. Therefore, when this is used, it can be used in this shape, that is, with the support pin provided in the end cap portion described below exposed. The example shown in FIG. 1 is such an example. For example, this shape can be used by placing it on a table or leaning against a wall, or by drilling holes according to the shape and dimensions of the support pins on the floor or dedicated stand, etc. You may use it in the form which hold | maintains an LED lighting fixture upright by inserting. Or you may use it by covering a support pin of an end cap part, for example in the form considered by the beauty | look, protection of an instrument, etc. Such an example will be described later in another embodiment. In this case, the cover may also serve as a holding base for the LED lighting apparatus.

  Alternatively, the LED lighting apparatus may be used by being attached to a dedicated holding device.

  Of course, it may be used by attaching it to an existing straight tube fluorescent lamp, and the support pin that can be attached to the socket of a straight tube fluorescent lamp makes it possible to use this kind of usage. Because.

  Thus, although various forms can be considered as the usage of the LED lighting apparatus as an apparatus, in any case, the connection method of the power line from the external power source and the power line provided on the LED lighting apparatus side is described above. All methods are applicable.

        (Straight tube type fluorescent lamp)

  In the present invention, the “straight tube fluorescent lamp” refers to a conventional straight tube fluorescent lamp, and more specifically, 2.3.1 “JIS C7617-2“ Straight tube fluorescent lamp—Part 2: Performance specification ”. This refers to the straight tube fluorescent lamp specified in the “List of data sheets”. Thus, the shape of the LED lamp portion in the present invention is a conventional straight tube fluorescent lamp shape so that it can be directly attached to a straight tube fluorescent lamp for mounting such a conventional straight tube fluorescent lamp. It is to make it. That is, in the present invention, the “straight tube fluorescent lamp” refers to a fluorescent lamp having a shape, size, and function that can be used with the conventional straight tube fluorescent lamp as described above.

  By making the LED lamp part into a straight tube fluorescent lamp shape in this way, LED lighting fixtures can be installed with relatively simple construction even when used by attaching to an existing straight tube fluorescent lamp. The installation cost is low and the waste of resources can be prevented. In addition, when used by attaching to an existing straight tube type fluorescent lamp as described above, the advantage of the fluorescent lamp alternative type LED lighting fixture that can maintain the atmosphere of the room at the time of the conventional fluorescent lamp can be maintained. It can also be demonstrated.

  In addition, as described below, a pair of end cap portions are provided at both ends of the LED lamp portion, and are configured to be attached to a conventional fluorescent lamp by means of support pins (corresponding to terminals of a straight tube fluorescent lamp). Therefore, the tube length of the LED lamp portion of the present invention is restricted to a size that can be attached to a conventional fluorescent lamp including the pair of end cap portions.

FIG. 4 is an exploded perspective view of FIG. For convenience of explanation, illustration of the end cap portion 0120b appearing on the right side in FIG. 1 is omitted. In this figure, the tube body 0211 constituting the LED lamp part 0210 is divided into a metal upper half body 0212 and a plastic lower half body 0213. Both halves are joined, for example, with an adhesive. Further, in the example shown in this figure, the metal portion of the tube body has an inwardly extending portion 0212a, and it is possible to enhance the heat dissipation effect by contacting the circuit board (not shown) at this portion. I have to.

  For example, an adhesive may be used for joining the LED lamp part and the end cap part. Or you may make it an LED lamp part and an end cap part turn independently.

  Further, as shown in the figure, a circular substrate 0270 made of a plastic material such as polychlorinated biphenyl is interposed between the LED lamp part 0210 and the end cap part 0220a so as to join them together. Good. By interposing such a board, when the LED lamp part and the end cap part can be rotated independently as described above, the effect that the contact part of the power line with the circuit board is less likely to be disconnected. is there. For example, an adhesive may be used for joining the LED lamp part and the end cap part. Or you may make it an LED lamp part and an end cap part turn independently. A specific example of such a configuration will be described later.

  Further, as shown in the figure, a circular substrate 0270 made of a plastic material such as polychlorinated biphenyl is interposed between the LED lamp part 0210 and the end cap part 0220a so as to join them together. Good. By interposing such a board, when the LED lamp part and the end cap part can be rotated independently as described above, the effect that the contact part of the power line with the circuit board is less likely to be disconnected. is there.

    (End cap part)

  Returning to FIG. 1, the end cap parts 0120a and 0120b are a pair of members provided at both ends of the LED lamp part, respectively, and can be attached to sockets of a straight tube type fluorescent lamp. And a support pin 0122 that is attachable to a socket of a straight tube fluorescent lamp and does not perform an electrical function.

  The main purpose of the end cap part is to enable the LED lamp to be mounted on a conventional fluorescent lamp as it is. Therefore, the end cap part is a cylindrical member having substantially the same tube diameter as that of the LED lamp, and the length of the end cap part is directly attached to the conventional fluorescent lamp with the end cap provided at both ends. The length can be regulated. The material of the end cap portion is not particularly limited, but for example, a metal one is used.

        (Support pin)

  The support pin 0122 is provided at the end of each of the pair of end cap portions (on the socket side of a conventional fluorescent lamp). This support pin is for making it possible to attach the LED lamp part and the end cap part as they are to the socket of the straight tube type fluorescent lamp. That is, this support pin corresponds to a terminal provided for electrical connection to a socket of a conventional fluorescent lamp fixture in a known fluorescent lamp type LED lighting apparatus. Accordingly, the size and shape of the support pin has a size and shape that can be attached to a socket of a conventional fluorescent lamp, and specifically, G13 defined in JIS C7601 “Fluorescent lamp (for general illumination)”. This applies to the caps related to.

  A difference from a terminal of a known fluorescent lamp type LED lighting apparatus is that the support pin does not perform an electrical function. "Does not perform an electrical function" means that it is not electrically connected to the socket of the fluorescent lamp, but simply connected to use as a support for holding the LED lamp portion with respect to the fluorescent lamp. This means that electricity does not flow between the LED lamp part and the socket via the support pins.

  In order to achieve the above object, the support pin needs to be insulated from other members of the LED lighting apparatus. With such a configuration, even if a current from the socket flows to the support pin, This current can be prevented from flowing to the LED lamp part via the support pin. Specifically, for example, when the upper half constituting the LED lamp part of the LED lighting apparatus is made of a conductive metal, the support pin does not come into contact with this so that the electric circuit is not short-circuited. There is a need to. Similarly, when the support pin is formed of a conductive member, it is necessary to prevent the two support pins from contacting each other. Thus, the support pin is configured to be completely insulated at the end cap portion.

  The material of the support pins is not particularly limited, and may be ceramics in addition to metals such as iron and stainless steel. However, in view of the necessity of insulation from the other members described above, those made of an insulating material are desirable.

  Thus, since the support pin does not perform an electrical function and is merely for holding the LED lighting apparatus and is completely insulated from other members, the LED lighting apparatus according to the present invention is Since the ballast provided in the LED lighting fixture itself and the ballast of the fluorescent lamp lamp act in a superimposed manner, there is no possibility of causing a fire accident or the like, and the safety is extremely high. As a result, the technical standards based on the Electrical Appliance and Material Safety Law can be cleared. Furthermore, the problem that the fluorescent lamp ballast itself consumes power wastefully can be solved.

  In addition, as a further effect that the support pin does not perform the electrical function, an existing circuit for lighting the fluorescent lamp when replacing the fluorescent lamp attached to the existing fluorescent lamp fixture with an LED lighting fixture is provided. There is no need to mess with it, and it can be left as it is. Therefore, even when the LED luminaire once replaced for some reason is returned to the fluorescent lamp again, it is only necessary to replace the LED luminaire with the fluorescent lamp, so that the replacement can be performed very easily.

  Furthermore, by leaving the existing circuit as it is, for example, in the case of a fluorescent lamp fixture 0971 of a type to which two fluorescent lamps are attached as shown in FIG. It is possible to attach the other one while keeping the other fluorescent lamp 0972 for the time being. Therefore, even when there is a need to gradually replace the fluorescent lamp with the LED lighting fixture due to budgetary reasons, it is possible to cope with this.

  As described above, since the LED lighting device of the present invention has a function as an independent device, it can be used simply by placing it on a table or leaning it against a wall with the end cap part exposed. It can also be used by covering the support pin of the end cap part with a cover. In these cases, the end cap portion has a purpose of protecting the LED lamp portion and maintaining the aesthetic appearance together with the cover.

  On the other hand, when the LED lighting fixture is used by being attached to an existing fluorescent lamp, it is possible to use various methods as described above for electrical connection with the power source. A method of using a power connector connected to the power line and a main body connector provided on the LED lighting apparatus side is conceivable. In this case, the end cap portion also has a purpose of storing a part of power from the main body connector portion to the circuit board and protecting it. Hereinafter, an example of a configuration in which the LED lighting apparatus includes a main body connector portion will be described.

        (Configuration example with main unit connector)

  FIG. 5 is a perspective view showing an example of the shape of an LED lighting apparatus having a main body connector portion. The LED lighting fixture 0500 shown in this figure has a main body connector portion 0530. The main body connector portion is for inputting power from a power source. The input of power from the power source is typically input of power from the primary power source, which means that power is taken directly from a power line (power line) such as a ceiling or wall. For this reason, also in the example of this figure, the main body connector portion is configured to be able to connect the power connector 0560 connected to the power line 0550 drawn from the primary power supply via the ceiling, wall, or the like. However, the main body connector portion may be used for inputting power from the battery in the event of a power failure, for example. This is a matter common to the power sources in the present invention.

  The main body connector portion constitutes one of the pair of connectors together with the power connector. There is no particular limitation on the method of connecting the main body connector and the power supply connector as long as they are electrically connected. For example, one is a female connector having a pair of pins, and the other is connected to this. A male connector with a corresponding pin receiving hole is conceivable. In this case, it is desirable that the main body connector portion is a female connector and the power connector is a male connector. This is because, by doing so, it is possible to prevent the risk of electric shock at the time of installation work and the like and to improve safety, and it is not necessary to provide a space for the connector on the main body side of the LED lighting apparatus. .

  FIG. 10 is a perspective view showing another example of the shape of the LED lighting apparatus having the main body connector portion. The main body connector portion and the power connector shown in this figure are connected to the main body connector portion 1030 provided in the notch portion 1023 of the end cap portion 1020a with the power connector 1060 substantially in the left-right direction (generally in the direction of arrow A in the drawing) Or a direction indicated by the A ′ direction). In the example of this figure, a power connector that is a male connector is inserted and connected to a main body connector portion that is a female connector as indicated by a thick arrow a. When the power connector is connected to the main body connector part from the substantially left-right direction as in the example of this figure, the power connector can be connected to the main body connector part after the LED lighting device is attached to the fluorescent lamp. In addition, it is possible to more easily perform the mounting operation of the LED lighting device. Or although illustration is abbreviate | omitted, you may make it connect a power supply connector from the back substantially with respect to the main-body connector part provided in the notch part of the end cap part. In the case of such a connection method, since the power connector can be connected to the main body connector portion after the LED illumination device is attached to the fluorescent lamp, the attachment operation of the LED illumination device can be performed more easily. . The shapes, dimensions, and specific arrangements of the main body connector portion and the power connector shown in FIGS. 5 and 10 are merely examples, and the male connector and the female connector (preferably the main body connector portion is the female connector) are electrically connected. Any device can be used as long as it can be connected to.

  As described above, unlike conventional fluorescent lamp type LED lighting fixtures, in the present invention, even when the LED lighting fixture is attached to an existing straight tube type fluorescent lamp fixture, power is input from the socket of the fluorescent lamp fixture. However, instead of this, electric power is directly input from the power supply via the main body connector portion. Since power is directly input from the power supply in this way, power is supplied without going through a ballast provided in the fluorescent lamp. Accordingly, it is possible to avoid the possibility of causing a fire accident or the like by the AC / DC converter and the ballast of the fluorescent lamp fixture provided in the LED lamp itself acting in a superimposed manner. It is therefore unnecessary to remove the ballast of the fluorescent lamp.

  Input from the power source is typically performed by connecting a single socket to a single power connector that is connected to the power lines from both the hot and cold sides. By doing in this way, it can comprise so that the arrangement position of a main-body connector part may be provided in the vicinity of one of a pair of end cap parts. Thereby, for example, in the case of attaching the main body connector part to the tip of the power line drawn from the end cap part, the length of the power line exposed from the end cap part can be shortened. It becomes easy and the appearance can be made clear.

  There is no particular limitation on the shape of the main body connector part. For example, the hot-side and cold-side terminals are simply attached to the ends of the two power lines drawn out from the small holes provided in the end cap part. May be. However, as a preferred example, as in the example shown in FIGS. 1 and 2, a notch portion is provided near the upper end of the end cap portion, and a pair of pins constituting the main body connector portion are erected here. Can be considered. In this case, when the main body connector portion is connected to the power connector, the power connector is fitted into the notch portion of the end cap portion. For this reason, the shape and size of the notch and the shape and size of the power connector are designed to fit and fit closely together. Furthermore, this shape is such that when the power connector is fitted into the notch portion of the end cap portion, the overall shape of the LED lamp portion, end cap portion, and power connector becomes a straight tube fluorescent lamp shape. It is desirable that the power connector is a shape obtained by cutting a part of the cylindrical end cap portion.

  Speaking of the example of FIG. 5, the shape and dimensions of the power connector 0560 are as follows when fitted into a notch 0523 provided near the upper end of the end cap part (main body connector part) 0520a. The shape and dimensions are such that the combined shape is exactly one cylindrical shape. Further, the pin 0530 constituting the main body connector portion standing on the notch portion and the pin receiving hole 0560a of the power connector are provided at positions where the power connector and the notch portion can be fitted closely.

  Although not shown, a pin receiving terminal connected to a power line (a part extending from the ceiling or the like to the power connector) 0550 is disposed in the pin receiving hole, and the pin of the main body connector portion is connected to the pin receiving hole. When the pin is inserted into the connector, the pin comes into contact with the pin receiving terminal so that power is supplied from the power connector to the main body connector portion.

  If the arrangement, shape, and dimensions of the end cap, main body connector (pin), and power connector are such, the power line exposed from the end cap can be completely eliminated. Can be made easier, and the appearance can be made clearer.

  The shape of the main body connector shown in FIG. 5 is merely an example, and may be different from this. For example, although not shown, a power connector may be connected to the main body connector provided in the notch portion of the end cap portion from substantially the left-right direction. In such a configuration, since the power connector can be connected to the main body connector after the LED lighting fixture is attached to the fluorescent lamp, it is possible to more easily perform the mounting operation of the LED lighting fixture. Become.

        (Configuration example in which the end caps can be pivoted independently of each other)

  The end cap part may be comprised from two members attached so that rotation independently was possible mutually.

  FIG. 6 is a diagram showing an example of the shape of the end cap portion of the LED lamp illumination device of the present embodiment, and the end cap portion is composed of two members that are rotatably attached independently of each other. It is shown that. 6A is a perspective view of the end cap portion, and shows one end cap portion 0620a of the pair of end cap portions (the other end cap portion is the same). (The illustration is omitted because it appears symmetrically). In the example of this figure, the end cap portion 0620a includes a cylindrical member (referred to as a “cylindrical member” for convenience) 0624 having substantially the same tube diameter as the LED lamp 0610, and an outer side of the cylindrical member (fluorescent lamp). A disk-shaped member (referred to as a “disk-shaped member” for convenience) 0625 having substantially the same diameter as the end cap portion disposed on the socket side of the lamp. A support pin 0622 for attaching the LED lighting device of the present invention to a straight tube fluorescent lamp is provided on the outer surface of the disk-shaped member (the surface on the socket side of the fluorescent lamp). The cylindrical member and the disk-shaped member are rotatably attached independently of each other. In the example of this figure, both members are independent of each other by a rivet 0691 (the top of the rivet appears in this figure) that passes through a small hole (not shown in this figure) drilled in the central portion of each member. It is semi-fixed so that it can rotate.

  FIG. 6B is a cross-sectional view taken along the line AA of FIG. 6A, in which a cylindrical member 0625 and a disk-shaped member 0626 (both indicated by diagonal lines rising to the right) A state is shown in which the rivets 0691 (shown by left-upward oblique lines) penetrating through the holes 0625a and 0626a are semi-fixed so as to be able to rotate independently of each other.

  Note that the rivet may be an eyelet-shaped one. In addition, a male screw is formed on one of the opposing surfaces of the cylindrical member and the disk-shaped member, and a female screw is formed on the other, so that they can be fitted gently so that they can be easily rotated by a human hand. It may be combined. Furthermore, the structure of the attachment part of the cylindrical member and the disk-shaped member is not limited to these. In short, any structure can be used as long as both members can be attached to each other so as to be easily rotatable without dropping off from each other. It may be a thing.

  According to such a configuration, when the LED lighting device is installed in an existing fluorescent lamp, the disk-shaped member of the end cap portion is maintained while keeping the LED lamp portion facing the desired illumination direction. Since it is possible to easily perform the operation of aligning only the direction with the socket of the fluorescent lamp, it is possible to easily perform the mounting operation of the LED lighting device.

  Further, as shown in the example of FIG. 6 (b), two substantially disk-shaped members 0627 having surfaces that mesh closely with each other are fixed to the opposing surfaces of the cylindrical member and the disk-shaped member, respectively. May be attached. As specific shapes of the surfaces where the members closely mesh with each other, for example, a wavy shape arranged radially, a dimple shape arranged on the circumference, and the like can be considered (shown in FIG. 6B). Is an example of the former). In addition, the fixing surface (the surface on the opposite side of the surface that meshes with each other) may be flat so that adhesion for fixing the respective members to the cylindrical member and the disk-shaped member is facilitated.

  In this case, the shapes of the surfaces of the two substantially disk-shaped members are formed in substantially the same shape. By fixing such a member to each of the cylindrical member and the disk-shaped member, the cylindrical member and the disk-shaped member are not only rotatable independently of each other, but also attached to a fluorescent lamp. In this state, the cylindrical member of the end cap part and the LED lamp part fixed thereto can be rotated and kept at an arbitrary position (angle).

  According to such a configuration, the LED element disposed in the LED lamp portion can be directed in an arbitrary direction. That is, the LED element has a certain degree of directivity in the direction of light emission. The LED elements are arranged so as to form, for example, a two-row array, and each array is arranged so as to emit light toward a diagonally outer direction (for example, a 45 degree direction) across the vertical axis. If it does so, the light from an LED element will not be directed directly but the part just under an LED lamp will be in a relatively dark state. Therefore, if the LED lamp is rotated using the above configuration and is kept at a position where one of the arrays illuminates directly below, it becomes possible to illuminate directly below. As in this example, it is possible to brightly illuminate any direction of the room by rotating the LED lamp so that the LED elements are oriented in any direction.

  FIG. 6C shows an example of the shape of the substantially disk-shaped member 0627, and shows an example of the point-symmetric waveform shape arranged radially, similar to the example of FIG. 6B. The member shown in this figure is also an example in which the fixing surface (not shown in this figure) is formed flat. In the example of this figure, since 24 waveforms are formed, the member fixed on the cylindrical member side is rotated, and the member on the disk-shaped member side is fitted at an arbitrary angle of every 15 degrees. It can be fixed while meshing. For this reason, it is desirable that all the waveforms are equiangular and have the same shape.

  <Effect>

  By the invention of the present embodiment, it is possible to avoid the problem of safety and the waste of power consumption, and can be installed with relatively simple construction when replacing the fluorescent lamp with the LED lighting fixture, It is possible to provide an LED luminaire that can maintain the advantages that the installation cost is low and the atmosphere of the room at the time of the conventional fluorescent lamp can be maintained.

  <Overview>

  The LED lighting fixture of this embodiment is basically the same as the LED lighting fixture of Embodiment 1, but further includes a detachable support pin cover that covers the support pin of the end cap portion to protect the support pin. It is a feature.

  <Configuration>

    (End cap: Support pin cover)

  The support pin cover is a detachable member that covers the support pin of the end cap portion and protects the support pin. “Cover on the support pin” may literally cover only the support pin, or may cover the entire end cap portion including the support pin, including both. This is because when the LED lighting device is used as an independent device, if the support pin is exposed, the support pin may hit the surrounding wall or furniture and bend or bend. It is a configuration. It also serves the purpose of preventing the appearance of the support pins from being lost.

  FIG. 7 is a diagram illustrating an example of a shape in a state where a support pin cover is attached to the LED lighting apparatus of the present embodiment. The support pin cover 0728 shown in FIG. 5A has a cylindrical shape (cylindrical container shape) with one side open, and the inner diameter of the cylinder substantially matches the outer diameter of the end cap portion, and includes an end including the support pin. The entire vicinity of the end of the cap can be covered. Thus, the support pin can be protected by covering the entire vicinity of the end cap portion with the support pin cover.

  In addition, in the example of this figure (a), although the example which covered the support pin cover only in one side of a pair of end cap parts was shown, you may be able to cover both.

  The shape of the support pin cover of the end cap portion shown in the figure is merely an example, and the specific shape is not limited as long as the support pin can be protected by covering the end cap portion. Also, the material of the support pin cover is not particularly limited as long as it has a strength that can protect the support pins. For example, metal, glass, resin, ceramic, wood, and the like are conceivable.

  In addition, the said support pin cover may serve as the holding stand of the LED lighting fixture. FIG. 6B shows such an example. Note that the shape of the support pin cover that also serves as a holding base in this figure is merely an example, and the specific shape is applicable as long as the support pin can be protected by covering the end cap portion and the LED lighting apparatus itself can be held. The shape does not matter.

  With this configuration, when the LED lighting fixture is used as an independent fixture rather than being attached to an existing fluorescent lamp, the support pin can be bent or bent by using the support pin exposed. Can be prevented, or the appearance can be prevented from being impaired.

  <Effect>

  According to the invention of this embodiment, when the LED lighting apparatus is used as an independent apparatus, the support pin can be prevented from being bent or bent by using the support pin exposed, or the appearance is impaired. Can be prevented.

  <Overview>

  The LED lighting fixture of this embodiment is basically the same as the LED lighting fixture of Embodiment 1 or 2, but it is straight tubed to prevent falling when the support pin is not supported by the straight tube type fluorescent lamp. It further has a connecting string for connecting to a type fluorescent lamp.

  <Configuration>

    (Concatenated string)

  The connecting string is a member for connecting itself to the straight tube fluorescent lamp in order to prevent falling in a state where the support pin is not supported by the straight tube fluorescent lamp.

  FIG. 8 is a conceptual diagram showing an example of the shape of the LED lighting fixture of the present embodiment, in a state where the LED lighting fixture is attached to the fluorescent lamp and cut along a vertical plane parallel to the major axis direction of the LED lighting fixture. (However, since it is a conceptual diagram to the last, it does not accurately show the shape in the cross section. In particular, the internal structure of the LED lighting fixture is omitted). For example, as shown in FIG. 5A, one end of a connecting string 0829 is attached to the inside of the fluorescent lamp 0871 with an adhesive or the like, and the connecting string is passed through a hole 0871a formed in the top plate or the like of the fluorescent lamp lamp. Then, the other one may be attached to the surface or inside of the end cap part 0820 of the LED lighting apparatus with an adhesive or the like. By doing so, as shown in FIG. 8B, even if the support pin 0822 is removed at any time, the LED lighting device stays in the air fishing state by the connecting string, and can be prevented from falling. Further, as shown in FIG. 8 (c), by attaching a stopper 0829a having a size that does not penetrate the hole in the middle of the string, the connecting string in the fluorescent lamp is not completely expanded, that is, You may make it stop in the state where the grade of the fall of a LED lighting fixture is small.

  The shape and material of the stopper are not limited, but for example, a substantially cylindrical shape as shown in FIG. 8 (c) (a shape slightly spreading downward) is conceivable. FIG. 8D is an enlarged perspective view showing this. The stopper 0829a shown in this figure is a member made of, for example, a rubber or a soft resin and having a substantially cylindrical shape (preferably having a slightly expanded shape). Can be pushed through the hole. For example, if a hole made in the top plate of a fluorescent lamp is passed from the lower side (floor side) to the upper side (ceiling side) (arrow direction) with the widened side down, after passing through the hole Since the bottom surface of the stopper is larger than the size of the hole, it does not penetrate from top to bottom, so that it can serve as a stopper. Although not shown in the drawings as shapes and materials that can achieve the same object, a plurality of petal-like members such as cloth and rubber may be bundled and one end tied with a string or the like. This stopper does not need to be fixed to the top plate surface, but is fixed to the connecting string, so that when the support pin is removed, the connecting string is pulled beyond the predetermined length beyond the predetermined length. It is enough if it is not put out.

  Alternatively, without providing such a hole, one of the connecting strings may be directly attached to the top plate of a fluorescent lamp or the like with an adhesive or the like.

  The “connecting string” is a string-like member, and any material and shape can be used as long as it is strong enough to support the LED lighting apparatus. Therefore, it may be a string such as a literal natural fiber or synthetic fiber, or a metal chain or wire. Further, the connecting string may also serve as a power supply circuit, so that it is not necessary to provide a separate member just for preventing the fall, and the structure of the LED lighting apparatus can be made efficient. In this case, the material of the connecting string is naturally limited to a conductive material.

  <Effect>

  According to the invention of the present embodiment, the LED lighting apparatus can be prevented from falling even when the support pin is not supported by the straight tube fluorescent lamp.
