Description

  The present invention relates to an LED lighting apparatus including a plurality of LED bodies that emit light when energized, that is, light emitting diodes.

  A conventional general illumination lamp is a fluorescent lamp, a cylindrical glass tube, a coiled electrode filament coated with a thermionic radioactive material inside each end of the glass tube, and fixed to both ends of the glass tube. And a pair of conductive shafts fixed to the outer surfaces of the caps. Further, mercury or argon gas is sealed in the glass tube, and a fluorescent paint is applied to the inner wall of the glass tube.

  In addition, for example, there is a type called a so-called slim line lamp which is mainly used in a relatively narrow space such as a show window or a display shelf and is turned on instantaneously. This slim line type lamp has a structure in which the electrodes are instantaneously discharged by a high voltage without preheating the electrodes while being in the cold cathode state.

  In recent years, illumination lamps using LED bodies have been proposed or marketed. There are various forms of this, but in general, a large number of LED bodies are mounted on the top surface, and the power supply for the lighting circuit and various electronic components are mounted on the back surface, so that the printed circuit board is light transmissive and shape retaining. Are housed and fixed in a glass or resin tube provided with the same, and two conductive shafts are provided at the ends, as in conventional fluorescent lamps (see Patent Documents 1 and 2).

  By the way, in the conventional fluorescent lamp or slim line type lamp, since there are caps at both ends of the glass tube, this portion becomes dark, the illumination effect is inferior, the life is short, and as a result, the cost performance is poor. Furthermore, it is inferior to LED lighting in terms of brightness, and a desirable lighting effect cannot be expected.

  In addition, since a conventional illuminating lamp using an LED body has a transparent cover body, each of the LED bodies is clearly recognized as a point and recognized as a sequence of points. At the same time, when the light from the LED body directly enters the eyes, it feels very dazzling. Furthermore, in order to prevent this glare, there is also a method of applying a milky white paint to the cover body. However, in this case, the line of glares and dots cannot be recognized, but the luminous flux (lm) decreases. The flying distance of light is also shortened. In addition, when the printed circuit board on which the LED body is mounted is fixed to the upper wall of the illuminating lamp body and this illuminating lamp body is also fixedly set on a display shelf or the like, the light irradiation direction is always limited to one direction. The In other words, because the light is applied only in one direction, once it is attached to a show window, etc., it is impossible to change the irradiation direction except to remove it once and change the emission direction to reattach it. is there. As a result, various lighting effects cannot be expected.

  Therefore, an object of the present invention is to freely change the irradiation direction of the irradiation light emitted from the LED body without giving a torsional load to the connection line connecting the luminaire main body and the LED illuminating lamp, and irrespective of the mounting posture of the main body. In addition, the color tone can be easily and freely changed, and when replacing the LED lighting, there is no mistake in the polarity of the power supply so that it can be safely mounted.

  In order to solve the above technical problems, an LED lighting apparatus according to the present invention emits light by energization in a main body case in which an electronic component including an LED power supply board is incorporated as described in claim 1. In an LED lighting apparatus including an LED illuminating lamp on which a large number of LED bodies are mounted, an LED support substrate on which the large number of LED bodies are mounted at predetermined intervals along the longitudinal direction, and the LED body A cover body having translucency covering the upper part, a holding body made of a material having high shape retention and heat conductivity for holding the LED support substrate and the cover body, end caps attached to both ends, and the end portions An LED illuminating lamp is composed of one conductive shaft body provided at the center of the cap and electrically connected to the LED body, and this LED illuminating lamp is attached to support members at both ends of the main body case. With the electrical connections 360 rotatably supported via a connecting member to perform with the conductive shaft, it is capable mounted detachably by freely pressing member detachably attached to the supporting member.

In the LED lighting apparatus having the above configuration, light with a relatively high luminance can be emitted with a low current by the LED body, so that it is possible to extend the life and reduce the power consumption.
In particular, the main body case is fixedly set on a display shelf or the like, but the LED illumination lamp is held on the support member so as to be able to rotate 360 degrees around the conductive shaft, and even after being set, the LED illumination The direction of the lamp support substrate, that is, the direction of the LED body can be freely changed 360 degrees from any position. Further, the LED lighting can be attached to and detached from the main body case simply by removing the presser member from the support member.

  Therefore, in the LED lighting apparatus according to claim 1 of the present invention, the LED support substrate on which the LED body is mounted is not fixed to the upper wall of the main body case as in the conventional LED lighting lamp, but from any position 360. The direction can be freely changed and the emission direction of the LED body can be changed. As a result, the main body case is fixedly set on a display shelf or the like, but the light irradiation direction can be freely changed, and various lighting effects can be expected. Moreover, since the printed circuit board is separated from the upper wall of the illuminating lamp as compared with the LED support board disposed directly on the upper wall of the main body case, the LED power source in the main body case, that is, the LED power source It is less likely to receive heat directly from the substrate and contributes to longer life.

  In addition, the LED illumination lamp can be easily and freely removed from or attached to the main body case by a simple operation of simply attaching and detaching the pressing member to and from the support member. Accordingly, the LED illumination lamp can be freely exchanged, for example, from blue to red, or from orange to white, and various illumination effects can be easily exhibited.

  Moreover, since the electrical connection between the LED lamp and the main body case is made by contact between the conductive shaft body and the connecting body, there is a problem of disconnection due to the rotation of the LED lamp as in the case of connection with a conventional electric wire. There is no risk of occurrence, contributing to a longer life.

In the above configuration, as described in claim 2 of the present invention, the outer peripheral surface of the end cap is formed with either a knurl or a plurality of concave portions provided at specified intervals in the circumferential direction, The support member of the main body case is provided with a protrusion that engages with the knurled or recessed portion, and prevents the LED illumination lamp from freely rotating around the conductive shaft body by its own weight, thereby providing position retention. Is desirable.
Since the holder used for heat dissipation is made of metal, the weight of the holder causes the LED illuminating lamp to turn with the holder downward, making it difficult to hold the original set position. This is because by engaging the protrusion with the knurling or the recess, the predetermined position can be easily maintained, and a desirable lighting effect can be exhibited.

In addition, as described in claim 3, it is desirable that the pressing member is screwed to the supporting member.
The means using the elastic reaction force inherent to the material of the presser member can be easily detached, and the LED lighting may be detached from the instrument. However, the risk can be prevented by screwing the support member. This is because it can be safely installed.

Furthermore, as described in claim 4, it is preferable that the pressing member includes a ridge covering the peripheral surface of the conductive shaft body and a ridge covering both the peripheral surface of the end cap.
This is because the number of parts used can be reduced, and both the ease of attaching and detaching operations and the reduction in price can be achieved.

In addition, as described in claim 5, it is desirable that the conductive shafts have different thicknesses on the left and right.
This is because positive and negative mounting mistakes can be prevented and safety can be improved.

Further, as described in claim 6, it is desirable that the holding body is made of aluminum die cast.
This is because the heat dissipation is high, so that the life of the LED lighting lamp and the reduction of power consumption can be more effectively achieved.

Furthermore, as described in claim 7, it is desirable that the holding body is provided with a plurality of grooves along the longitudinal direction at predetermined intervals in the circumferential direction.
Combined with the use of aluminum die-casting as a material, heat dissipation can be further enhanced, and the presence of multiple grooves allows the standing plate between the grooves to function as a flange, even if it is long This is because even a simple LED illumination lamp can well prevent the possibility of inadvertent bending and deformation.

Further, as described in claim 8, it is desirable that the case body is provided with a grounding pin in addition to the input / output electrode pins.
This is because it can be used not only in Japan but also in other countries and can expand versatility.

Furthermore, as described in claim 9, the bottom wall of the main body case has an inverted L-shaped cross section, and the L-shaped stem portion extends along the vertical direction so that the arm portion moves away from the bottom wall. It is desirable that the lateral mounting pieces to be mounted are provided integrally or integrally.
By attaching the arm part to the fixed wall, the LED lighting device can be attached to the fixed part of the show window or lighting signboard, for example, as shown in FIG. This is because the vertical width for the above can be made as narrow as possible, and the securing of the height space can be effectively realized.

The LED illumination lamp is shown, (A) is a partially cutaway front view, and (B) is a cross-sectional view taken along the line BB in (A). It is a figure showing the inner side of an end cap.

  As shown in FIGS. 1 and 2, the LED illuminating lamp 10 includes an LED support substrate 12 made of an aluminum die-cast flat plate material in which a large number of LED bodies 11 are mounted in a line along the longitudinal direction, Covering the upper part of the LED bodies 11 arranged in a row, specifically, a translucent cover body made of a synthetic resin which is translucent and has a shape-retaining property and has a C-shaped cross section. Part) 13, the LED support substrate 12 and the cover body 13, a semimoon-shaped aluminum die-cast holder 14, a pair of sheath-shaped end caps 15, and the sheath-shaped end caps 15 And a conductive shaft body 18 which is fixed to the LED body 11 with a screw 16 from the inside and is electrically connected to the LED body 11 via a conductive wire 17. The overall shape is elongated, and the cross section is cylindrical, forming an elongated tube.

  The LED body 11 is a type in which 55 pieces are mounted, although a part of the length is omitted in the illustrated example. The interval between the LED bodies 11 is set to approximately 10 mm between the centers of the adjacent LED bodies. It should be noted that the LED body 11 can be employed in any form other than the chip type shown in the figure, such as a bullet type or other appearance.

  For example, the LED support substrate 12 has an aluminum plate having a length of about 550 mm, a width of about 11 mm, and a thickness of about 0.8 to 1.2 mm, and a pair of electrodes for electrically connecting the LED bodies 11 to the upper surface thereof. The printed circuit board is made of a synthetic resin to which a conductive pattern is applied.

Further, as shown in FIGS. 2A, 2B, and 3, the sheath-shaped end cap 15 has a thickness corresponding to the thickness of the cover body 13 from the cylindrical inner peripheral surface 15A to the center side. The inwardly facing C-shaped piece portions 15B are integrally formed with the above-mentioned distance between them, and the end portion of the cover body 13 is held between each cylindrical inner peripheral surface 15A and the C-shaped piece portion 15B.
In addition, inward flange portions 19 are integrally provided at both lower ends of the cover body 13.

As shown in FIGS. 2 and 4, the holding body 14 has a flat shape on the upper surface and a curved surface on the lower portion, and has a half-moon shape constituting the lower third of the cylinder.
The locking groove 20 is formed in a longitudinal direction from the left and right end portions of the upper surface, and has a U-shaped cross-sectional piece that locks the flange portion 19 by inserting the flange portions 19 at the left and right ends of the cover body 13. The holding groove 21 is formed in the lower portion in the same manner in the longitudinal direction, and has a U-shaped cross-section inwardly holding the LED body support substrate 12 by inserting the left and right ends of the LED body support substrate 12. Is equipped. In addition, the holding body 14 is provided with a pair of vertical grooves 14A along the longitudinal direction, which controls heat dissipation, in the center in the width direction of the holding body 14 and on the left and right sides thereof. One in the center is opened upward, that is, is released facing the back surface of the LED body support substrate 12, and the other pair is opened downward, that is, open to the outside. The end cap 15 is fixed by screwing a screw 14B into the central longitudinal groove 14A from the outside of the end cap 15 to form an LED illumination lamp. 14C is a standing plate portion formed between the vertical grooves 14A, which functions as a flange, so that even if it is a long LED lighting lamp, it is possible to successfully prevent the possibility of inadvertent bending and deformation.

  Further, as shown in FIGS. 1, 2A, 2B, and 3, a knurl 22 is formed over the entire region in the circumferential direction on the cylindrical outer peripheral surface of the end cap 15. As will be described later, the knurling 22 engages with a braking protrusion provided on the support member 7 and applies braking to the free rotation of the LED lighting lamp 10 around the conductive shaft 18. It is.

  The conductive shaft 18 has different diameters on the left and right. This is a consideration for eliminating the mistake of attaching the positive and negative power supply polarities when the support member 7 is mounted, so that it can be used safely.

  As shown in FIGS. 1, 8, and 12, the brush spring mounting plate 23 faces upward from the upper surfaces of the end portions of the input / output terminal block 8 and the connection output terminal block 9 mounted in the end cap 6. Are projecting together. At the center of the brush spring mounting plate 23, an upwardly open corner U for mounting a pair of left and right brush springs 24 as an example of a connecting body that is electrically connected to the conductive shaft body 18 of the LED lighting lamp 10. A character-shaped receiving hole 23A is provided, and the pair of left and right brush springs 24 are fitted therein. The pair of left and right brush springs 24 are connected together by connecting pieces 24A at the lower ends thereof, and are set at an interval just equal to the width of the rectangular U-shaped receiving hole 23A. Thus, the conductive shaft 18 is elastically clamped from the left and right. Further, a downward claw 23B is integrally projected from the inner surface of the upper end of the receiving hole 23. By engaging the upper end of the brush spring 24, the brush spring 24 is prevented from being detached, and the conductive shaft body is provided. The spring elasticity for elastically holding 18 is maintained.

  On the other hand, as shown in FIGS. 7 and 11, the support member 7 is provided with a pothole 25 connected to the inside of the end cap 6 on the inner side of the end cover plate section 7 </ b> A. From the upper surface of the end cap 6, a pair of left and right conductive shaft insertion arms 26 are integrally projected. A receiving portion 26 </ b> A of a U-shaped conductive shaft 18 is formed at the base end of the conductive shaft body insertion arm 26 from one side to the other. When the input / output terminal block 8 and the connection output terminal block 9 are respectively mounted on the end cap 6, the brush spring mounting plate 23 is exposed upward from the hole 25 and auctions up, and the desired conductive shaft is formed. The support posture of the body 18 is maintained.

  A semicircular receiving rod 27 is integrally provided on the upper wall C of the end cap 6 on the inner side of the arm 26 for inserting the conductive shaft body, that is, on the main body case 3 side. The radius of curvature of the receiving rod 27 is formed to be substantially the same as the radius of curvature of the outer periphery of the end cap 15 of the LED lighting lamp 10, and the end cap 15 can be fitted into the inner circumference of the receiving rod 27 well. Set to dimensions.

  Moreover, the inner peripheral surface of the upper end of the receiving rod 27 protrudes inward, engages with the knurled 22 of the end cap 15 of the LED lighting lamp 10, and centers on the conductive shaft 18 of the LED lighting lamp 10. A protrusion 28 is provided integrally to apply braking to the free rotation. The knurl 22 and the protrusion 28 constitute a rotation braking structure B with the LED illumination lamp 10. A pair of protrusions 28 may be provided on the left and right of the receiving rod 27, or either one may be provided. Further, only one support member 7 may be provided, or both support members 7 may be provided. This rotational braking structure S is very useful in that it can well prevent the possibility that the holding body 14 is in the lower position and the LED body 11 faces upward due to the weight of the holding body 14 and the original lighting effect cannot be exhibited. In addition, it is very useful for delicate position adjustment.

Further, as shown in FIGS. 1, 6 to 7, and 10 to 11, the presser cover covers the pothole part 25 from above the pothole part 25 and the knurled part 22 of the end cap 15 of the LED lighting lamp 10. A covering member 29 as an example of the member is provided.
The cover member 29 includes a semicircular cover portion 29A having a radius of curvature substantially the same as the radius of curvature of the outer periphery of the end cap 15 of the LED lamp 10, and the center of the inner peripheral surface of the cover portion 29A. A downward-facing hanging piece 29C having a semicircular cutout 29B that matches the outer dimension of the conductive shaft 18 is provided at the lower end of the lower end. The lateral width of the hanging piece 29C is formed to be equal to the distance between the pair of left and right conductive shaft insertion arms 26, and the covering member 29 is placed on the covering hole portion 25 from above. The hanging piece 29C is accommodated between the conductive shaft body insertion arms 26, and a circular insertion hole is formed between the receiving portions 26A of the conductive shaft body insertion arms 26, so that the conductive shaft body 18 can be successfully used. I can support it. Moreover, a sheath is formed by the covering portion 29 </ b> A of the covering member 29 to cover the outer periphery of the end cap 15 of the LED lighting lamp 10.

  Further, as shown in FIGS. 6, 7, 10, and 11, the covering member 29 is screwed from the outside of the end covering plate portion 7 </ b> A of the supporting member 7 to a boss portion 29 </ b> D integrally provided on the upper portion of the hanging piece 29 </ b> C. The end cover plate portion 7A is detachably attached via 30.

  Further, both the width of the receiving hole 23A of the brush mounting plate 23 and the interval between the conductive shaft insertion arms 26 are set to the same size in accordance with the diameter of the corresponding conductive shaft 18 so that they are opposite to each other. Insertion is not possible. Furthermore, the knurl 22 can cope with fine angle changes and is ideal, but can be replaced with other means. For example, although not shown in the figure, it may be possible to adjust in multiple stages by recesses provided at predetermined intervals.

  As described above, in the LED lamp 10, the conductive shaft 18 is held by the receiving portion 26A or the receiving rod 27 of the brush spring 24 or the conductive shaft insertion arm 26, and the upper surface of the upper wall 2A of the main body case 3 As shown in FIGS. 5, 6, and 10, a slight gap S, approximately 2 to 3 mm, exists between the lower surface of the 14 so as to smoothly rotate 360 degrees. Has been. Therefore, the presence of the gap S reduces the possibility that the printed board of the LED lighting lamp and the LED body 11 is directly affected by the heat generation of the LED power supply board 4 accommodated in the main body case 3. Therefore, unlike the conventional case in which the printed circuit board is directly attached to the main body case, the disadvantage of damaging the LED body 7 in the early stage is eliminated, which contributes to a longer life.

  As shown in FIG. 1, a substrate insulating cylinder 31 made of polycarbonate and having a size slightly smaller than that of the main body case 3 is housed in the main body case 3 so as to be insertable / removable. The substrate insulating cylinder 31 has a rectangular cross section and is formed in a short cylindrical body, and the LED power supply board 4 is inserted and mounted therein.

  The LED power supply substrate 4 and the connecting piece 24A of the brush spring 24 are electrically connected to each other by one lead wire 24B, as shown in FIG. In particular, a configuration is adopted in which one of the conductive shafts 18 of the LED lighting lamp 10 is connected to the positive pole and the other is connected to the negative pole. 8 and 12, reference numeral 24C denotes a recessed groove provided in the base of the brush spring mounting plate 23. By inserting the lead wire 24B, the brush mounting plate 23 can be smoothly inserted into the hole 25. It can be done.

Since the basic structure of the end cap 6 is the same on both the left and right sides, first, the structure of the common part will be described based on the description of FIGS.
First, the overall shape and dimensions are the same as those of the main body case 3, and a fitting portion 6 </ b> C that is fitted into the opening 5 of the main body case 3 is integrally provided at one end side. Needless to say, the fitting portion 6C is designed so that its outer dimensions and shape substantially match the inner diameter size and shape of the main body case 3, but its lower portion is released. On the other end side, the support member 7 is integrally raised upward. In addition, a rectangular (specifically hexagonal) through hole 6E is provided in the lower portion of the outer wall 6D of the end cap 6 in a direction orthogonal to the longitudinal direction of the main body case 3. This is for inserting a plug to an AC 100V power source or a connector to another LED lighting apparatus 1A (see FIGS. 14 and 15). Further, a slit 6G is provided at three sides in the center of the upper wall 6F of the fitting portion 6C, and the remaining one side is connected to the upper wall 6F so that the free end can be moved up and down elastically, and the locking projection. 6H is provided integrally. The main body case 3 is fitted into an engagement hole 2 </ b> B provided in the upper wall 2 </ b> A to prevent the main body case 3 from coming out. The upper wall 6F covers the entire region of the end cap 6. In addition, a pin insertion cylinder 6I is integrally suspended from the inner surface of the upper wall 6F, and an engagement pin 6K is integrally raised from the inner surface of a retrofit bottom wall 6J. By inserting and inserting into the pin insertion cylinder 6I, it is possible to perform mutual positioning and assembly.

Next, both the input / output terminal block 8 and the connection output terminal block 9 are integrally formed with a pair of electrode pins 32 at an appropriate interval on the left and right sides and a grounding pin 33 at an interval above them. Is provided.
As shown in FIGS. 6 to 9, the input / output terminal block 8 is provided with a top plate 8A, a rear wall 8B, a left and right wall 8C, and a bottom wall 8D, each having a slope that spreads from the left to the right. It has a box shape with a recessed space 8E that is open on the through hole 6E side, and the electrode pin 32 and the grounding pin 33 are integrally supported by the rear wall 8B, and the recessed portion 8E is in the recessed space 8E. Thus, it is arranged to project toward the through hole 6E side. A plug 35 of the electric cord 34 connected to an AC 100V power source is inserted here. The electrode pins 32 are electrically connected to the LED power supply substrate 4 via lead wires 36 (see FIG. 1). The grounding pin 33 is electrically connected to the case main body 3 via a lead wire 37.

  In addition, as shown in the figure, the connection output terminal block 9 has a U-shaped European character formed of a top plate 9A, a rear wall 9B, and a bottom wall 9C each having a slope that spreads from side to side. The block body 39 is provided so as to project integrally from the rear wall 9B. The electrode pin 32 and the grounding pin 33 are integrally supported at the base end by the rear wall 9B and surrounded by the block body 39. The block body 39 has a size such that the upper and lower surfaces are spaced from the top plate 9A and the low wall 9C, and the side surfaces are spaced apart from the corresponding positions of the left and right end portions of the top plate 9A, the bottom wall 9C and the rear wall 9B. It is configured. A lead wire 36 connected to an AC 100V power source branched from the LED power source substrate 4 is connected to the electrode pin 32 on the connection output terminal base 9 side. The grounding pin 33 is electrically connected to the case body 3 through a lead wire 37. The presence of the block body 38 is not misunderstood as the AC 100V power supply insertion side of the input / output terminal block 8 and helps to ensure safety.

  Then, as shown in FIG. 14, the connection pin or the connector for supplying power to the other LED lighting lamp 1A connected next to the electrode pin 32 on the connection output terminal base 9 side as shown in FIG. 39 is connected.

  FIG. 14 shows an example in which the LED lighting fixture 1 and another LED lighting fixture 1A are connected by the connection cord 39. However, as shown in FIG. It is also possible to directly connect the end cap 6 on which the terminal block 9 is set and the end cap 6 on which the input / output terminal block 8 of another LED lighting apparatus 1A is set. As shown in FIG. 2B, this connection block body 40 includes a recessed portion 40A that can be fitted into the block body 38 from the middle, and the other is configured as a block body 40B, so that another LED illumination is provided. It is comprised so that it can fit in the input-output terminal block 8 of the instrument 1A. A pair of left and right connecting pins 40C is provided from the recessed portion 40A to the block body 40B. The ground pin 41 is also provided in the same manner.

  When this connection block body 40 is used, as shown in FIG. 15A, the end cap 6 on which the connection terminal block 9 is set and the input / output terminal block 8 of another LED lighting apparatus 1A are set. The end caps 6 can be connected in close contact with each other, and a large number of LED lighting fixtures can be obtained as a single serial illuminating body.

Moreover, FIG. 16 shows the structure of the horizontal attachment piece 42 for attaching the LED lighting fixture 1 sideways to the fixing | fixed part F. FIG.
This is because the vertical width for mounting can be made as narrow as possible, and the securing of the height space is effectively realized. In practice, the vertical height in the case of the vertical orientation is approximately 40 mm, but when it is in the horizontal orientation, the height can be reduced to approximately 25 mm.
Specifically, as shown in FIG. 16 (A), the cross-sectional shape is an inverted shape of the letter L, the L-shaped stem portion 42A is along the vertical direction, and the arm portion 42B is the main body. The case 3 is integrally extended in a direction away from the bottom wall 3 </ b> A of the case 3. The stem portion 42A and the arm portion 42B are respectively provided with screw holes 42C. 43 is a screw for mounting.

In the example shown in FIG. 16 (B), it is attached to the main body case 3 via the vertical attachment 44.
The vertical mounting tool 44 is a jig for mounting the LED lighting device 1 in the vertical direction as shown in FIG. It has a U-shaped cross section and is provided with scissor claws 44A on both sides, and the main body case 3 is elastically sandwiched via the scissor claws 44A.

  In this case, it goes without saying that only the lateral attachment piece 42 may be directly attached to the bottom wall 3 </ b> A of the main body case 3 without using the vertical attachment 44.

The

  The LED lighting apparatus 1 of the embodiment configured as described above has the following effects in addition to the effects described in the structural description.

  Since the direction of the LED body 7 can be freely changed 360 degrees from any position even after the LED lighting apparatus 1 is attached to a display shelf or a show window, it can be changed to only one direction in the past. Compared to those that could not be emitted, a much more efficient and variety of lighting effects can be obtained. In addition, by directing the cover body 13 of the LED illuminating lamp 10 toward the main body case 3, the light from the LED body 11 does not directly enter the human eye, and can be used as indirect lighting that is gentle on the eyes. Enables a variety of lighting.

  Further, the LED illumination lamp 10 can be attached to and detached from the case main body 3 by a simple operation of simply attaching and detaching the cover member 29 to and from the support member 7, and thus the attachment and detachment operation is very easy and simple. Accordingly, the LED illumination lamp 10 can be freely exchanged, for example, from blue to red, or from orange to white, and various illumination effects can be easily exhibited.

  In addition, since the electrical connection between the LED lamp 10 and the main body case 3 is performed by the contact between the conductive shaft 18 and the brush spring 24 as a connection body, the LED lighting is similar to that connected with a conventional electric wire. There is no risk of disconnection troubles due to the rotation of the lamp 10, contributing to a longer life, simplifying the manufacturing and assembly work processes and labor, and providing easy and inexpensive manufacturing. Can contribute. Further, since the diameter of the conductive shaft body is different on the right and left, the replacement of the LED lighting lamp 10 can be safely performed without any mistake in attaching the power supply polarity.

  Further, the knurl 22 formed on the outer peripheral surface of the end cap 15 and the projection 18 provided on the receiving rod 27 of the support member 7 of the main body case 3 so as to engage with the knurl 22 of the LED illuminating lamp 10. Since the rotation braking structure B is provided, it is possible to prevent the LED lighting lamp 10 from freely rotating around the conductive shaft body 18 by its own weight, and depending on the weight of the metal holding body 14 used for heat dissipation. The LED illumination lamp 10 can be rotated with the holding body 14 in the downward direction, and the problem that it is difficult to maintain the original set position can be solved well, the predetermined position can be easily maintained, and the desired illumination effect can be obtained. Can demonstrate.

  Further, since the cover member 29 is detachably attached to the support member 7 with screws 16, for example, the cover member 29 is made of synthetic resin and is attached and detached using the elastic reaction force inherent to the material. As compared with the above, the covering member 29 is not easily detached, and the possibility that the LED lighting lamp 12 is inadvertently detached from the appliance can be prevented in advance, and a safe attachment is possible.

  Further, the cover member 29 includes a hanging portion 29C for holding the conductive shaft body 18 and a cover portion 19A for covering the peripheral surface of the end cap 15 together with the receiving portion 26A of the conductive shaft body insertion arm 26 on the support member 7 side. As a result, the number of parts used can be reduced, and both the ease of attaching and detaching operations and the reduction in price can be achieved.

  As shown in FIGS. 5, 11, and 15, a gap S is positively provided between the upper surface of the upper wall 2 </ b> A of the main body case 3 and the lower surface of the holding body 14 that holds the LED body support substrate 12 and the cover body 13. Thus, it goes without saying that the LED illumination lamp 10 is smoothly rotated, and the LED body 11 may be directly affected by the heat generated by the LED power supply substrate 4 housed in the main body case 3. Less. Therefore, unlike the conventional case in which the printed circuit board is directly attached to the main body case, the drawback of damaging the LED body 11 in the early stage is eliminated, which contributes to a longer life.

  Further, by providing the grounding pin 33 together with the electrode pin 32, it can be used not only in Japan but also in other countries and can be widely used.

  Since the holding body 14 is provided with a pair of vertical grooves 14A along the longitudinal direction for controlling heat dissipation in the center in the width direction of the holding body 14 and on the left and right sides thereof, aluminum die-casting is used for the material. Combined with the use, the heat dissipation can be further enhanced, and the presence of the plurality of vertical grooves 14A allows the standing plate portion 14C between the vertical grooves 14A to function as a flange, Even if it is a simple LED illuminating lamp, the possibility of inadvertent bending and deformation can be well prevented.

  The LED lighting apparatus 1 according to the present invention described above is not limited to being applied for display shelf or show window lighting, but can be used in various fields such as various signboard materials or general lighting apparatus. Needless to say, it can be applied. In the illustrated example, a 3-pin system is adopted, but a 2-pin system excluding the grounding pin 33 is employed as necessary. Further, although not shown, a closing lid having the same shape as the through hole 6E is detachably attached to the through hole 6E of the end cap 6 on the side to which the other LED lighting apparatus 1A is connected. When the other LED lighting apparatus 1 </ b> A is not connected, the end portion is kept beautiful, and the connection portion is protected.

  The LED lighting apparatus 1 according to the present invention can freely rotate the irradiation direction of the light emitted from the LED body 11 360 degrees from any position regardless of the mounting posture of the case body 3, so that a show window or a display shelf can be rotated. Furthermore, the present invention can be applied not only to illumination lamps such as various lighting signs but also to a general household, for example, as a tabletop, a floor stand, or an indoor indirect illumination lamp.
