Description

TECHNICAL FIELD The present invention relates to an LED lighting device and an LED lighting fixture including the LED lighting device.

LED lighting fixtures using LEDs (Light Emitting Diodes) are known. For example, as an LED lighting fixture installed on a ceiling, there is known a lighting fixture that includes a long LED lighting device called a light bar and a long lighting device body having a concave portion to which the LED lighting device is detachably attached. (Patent Document 1).

This type of LED lighting device includes a long substrate, a plurality of LEDs mounted on the substrate, a long translucent cover member that covers the plurality of LEDs, and a cover member that supports the substrate and supports the substrate. and an elongated frame to which is attached.

The frame has, for example, a main plate portion to which a substrate on which LEDs are mounted is attached, and a pair of side plate portions extending from both ends in the short direction (width direction) of the main plate portion toward the ceiling. The side plate portion of the cover member is attached to the side plate portion of the frame.

As described above, the conventional frame has a substantially U-shaped cross section, and a concave portion surrounded by the main plate portion and the pair of side plate portions is formed on the rear side (ceiling side) of the frame. A power supply device and a functional part such as a sensor unit are placed in the concave portion of the frame.

JP 2014-116299 A

If the frame is provided with a pair of side plates extending toward the ceiling (that is, if the cross-sectional shape of the frame is substantially U-shaped), the ceiling side of the frame is connected to the power supply and functional parts. The wiring space for arranging the conductive lines to be connected becomes narrower.

Therefore, it is conceivable to configure the frame so that the pair of side plate portions is not provided. For example, it is conceivable to configure the frame only by flat plate members.

However, simply making the overall shape of the frame flat will reduce the strength of the frame and reduce the rigidity of the LED lighting device. Therefore, there is a possibility that the frame is deformed and the LED lighting device is deformed.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and provides an LED lighting device and an LED lighting fixture that can suppress deformation of the frame even if the main plate portion to which the substrate is attached is flat. With the goal.

In order to achieve the above object, one aspect of the LED lighting device according to the present invention includes a substrate on which LEDs are arranged, a long frame to which the substrate is attached, and the frame so as to cover the LEDs. and an elongated cover member attached thereto, wherein the frame has a portion to which the substrate is attached and which is formed in a flat plate shape as a whole, and the portion extends along the longitudinal direction of the frame. It has at least one ridge reinforcement.

Further, one aspect of an LED lighting fixture according to the present invention includes the LED lighting device described above and a fixture body that holds the LED lighting device.

Even if the main plate portion to which the substrate is attached is flat, deformation of the frame can be suppressed.

AC power is supplied through the The power terminal block 8 is installed in the concave portion 2a of the instrument main body 2. As shown in FIG.

Next, the detailed structure of the LED illumination device 3 will be described using FIGS. 4 to 7 while referring to FIGS. 1 to 3. FIG. 4 is a perspective view of the LED lighting device 3 according to Embodiment 1 when viewed from the cover member 30 side, and FIG. 5 is a perspective view of the same LED lighting device 3 when viewed from the back side. FIG. 6 is a cross-sectional perspective view of the same LED lighting device 3. As shown in FIG. FIG. 7 is an exploded perspective view of the same LED lighting device 3. As shown in FIG.

As shown in FIGS. 2, 4 and 5, the LED lighting device 3 is an elongated line light source called a light bar. The LED lighting device 3 emits light of a predetermined color such as white light.

As shown in FIGS. 3, 6 and 7, the LED lighting device 3 includes a substrate 10, LEDs 20 arranged on the substrate 10, a cover member 30 covering the LEDs 20, a frame 40 supporting the substrate 10, an end and a cap 50 .

The substrate 10 is a mounting substrate for mounting the LEDs 20 thereon. In this embodiment, the substrate 10 is formed in a substantially rectangular shape elongated in the longitudinal direction (Y-axis direction) of the frame 40 . The thickness of the substrate 10 is, for example, 1.0 mm. The substrate 10 may have a length substantially equal to the length of the frame 40 in the longitudinal direction, or a plurality of substrates 10 may be arranged along the longitudinal direction of the frame 40 . As shown in FIG. 7, in this embodiment, two substrates 10 are arranged along the longitudinal direction of the frame 40 .

As shown in FIGS. 6 and 7, the substrate 10 has a first surface 10a, which is one surface, and a second surface 10b, which is the other surface facing the first surface 10a. The first surface 10a of the substrate 10 is the front surface on which the LEDs 20 are mounted. On the other hand, the second surface 10 b of the substrate 10 is the back surface facing the frame 40 . In this embodiment, the second surface 10b of the substrate 10 is in contact with the frame 40. As shown in FIG.

The board 10 is, for example, a printed wiring board (printed board) on which metal wiring is formed in a predetermined pattern. In addition, a resist made of an insulating resin material may be formed on the surface of the substrate 10 so as to cover the wiring in order to protect the wiring and ensure a dielectric strength voltage. The substrate 10 may be a single-sided wiring board in which wiring is formed only on the first surface 10a on which the LEDs 20 are mounted, or a double-sided wiring substrate in which wiring is formed on each of the first surface 10a and the second surface 10b. may be

The base material constituting the substrate 10 includes a resin substrate made of an insulating resin material, a ceramic substrate made of a sintered body of a ceramic material such as alumina, and a metal substrate made of a metal material such as aluminum or copper. A metal base substrate or the like obtained by applying is used.

In the case where the substrate 10 is made of a resin substrate, the resin substrate may be, for example, a glass epoxy substrate (CEM-3, FR-4, etc.) made of glass fiber and epoxy resin, craft paper or the like, and phenol resin. A paper phenol base material (FR-1, FR-2), a paper epoxy base material (FR-3) composed of paper and epoxy resin, or a polyimide substrate made of polyimide or the like can be used. Further, the substrate 10 may be a rigid substrate or a film-like flexible substrate.

Metal wiring formed on the substrate 10 is electrically connected to the power supply device 4 . In this case, electrodes or connector terminals formed on the substrate 10 and the power supply device 4 are connected by conductive wires. A conductive wire that connects the substrate 10 and the power supply device 4 is inserted through, for example, a through hole provided in the frame 40 .

As shown in FIGS. 6 and 7, a plurality of LEDs 20 are mounted on the first surface 10a of the substrate 10. FIG. In this embodiment, the plurality of LEDs 20 are mounted linearly in a row along the longitudinal direction (Y-axis direction) of the substrate 10 at predetermined intervals. Specifically, the plurality of LEDs 20 are mounted over substantially the entire length of the cover member 30 and the frame 40 in the longitudinal direction. In addition, along the longitudinal direction of the board|substrate 10, several LED20 may be mounted not in one row but in multiple rows.

LED20 is an example of a light emitting element. In the present embodiment, each of the plurality of LEDs 20 is an individually packaged SMD structure LED element (LED light source). In this case, each LED 20 includes a white container (package) made of resin or ceramic, an LED chip (bare chip) arranged in the container, and a sealing member that seals the LED chip. In this embodiment, the LED 20 is a white LED element that emits white light. In this case, for example, a blue LED chip that emits blue light when energized is used as the LED chip, and a silicone resin containing a yellow phosphor such as YAG (fluorescent body containing resin) is used.

The plurality of LEDs 20 emit light by direct current supplied from the power supply device 4 via conductive lines connecting the power supply device 4 and the substrate 10 .

A plurality of LEDs 20 are covered with a cover member 30 . Specifically, all the LEDs 20 are covered with the cover member 30 . The cover member 30 is an example of a translucent cover having translucency, and transmits light emitted from the LEDs 20 . In the present embodiment, the cover member 30 is a diffusion cover that not only has translucency but also has diffusivity. Therefore, the light from the LEDs 20 incident on the cover member 30 is diffused (scattered) by the cover member 30 and passes through the cover member 30 .

As shown in FIGS. 3 and 6, the cover member 30 covers the substrate 10. As shown in FIG. Specifically, the cover member 30 is arranged to face the first surface 10a of the substrate 10 so as to cover the plurality of LEDs 20 . In this embodiment, the cover member 30 covers the entire substrate 10 on which the LEDs 20 are arranged.

As shown in FIGS. 5 and 6, the cover member 30 also covers the frame 40 on which the substrate 10 is arranged. In this embodiment, the cover member 30 covers the entire frame 40 on which the board 10 is arranged. The cover member 30 is elongated in the Y-axis direction similarly to the substrate 10 and the frame 40 .

The cover member 30 is attached to the frame 40 . A cylinder is formed by the cover member 30 and the frame 40, and the substrate 10 and the plurality of LEDs 20 mounted on the substrate 10 are housed in this cylinder.

The cover member 30 is attached to the frame 40 so as to cover the board 10 and the LEDs 20 . As shown in FIGS. 3 and 6 , the cover member 30 has a cover body portion 31 and an attachment portion 32 connected to the cover body portion 31 .

As shown in FIG. 7, the cover main body 31 is elongated in the Y-axis direction and formed in a gutter shape. The cover body portion 31 has, for example, a flat, substantially semi-cylindrical shape. Therefore, the cover body portion 31 has an elongated rectangular opening end surface extending in the Y-axis direction. Further, the cross-sectional shape of the cover main body portion 31 when cut along the X-axis direction has a curved shape curved in a substantially circular arc shape.

As shown in FIGS. 3 and 6 , the cover main body 31 includes a protruding portion 31 a that protrudes outward in the width direction of the cover main body 31 from the mounting portion 32 . The projecting portions 31 a are formed at both ends of the cover body portion 31 in the short direction (width direction). Each projecting portion 31a has a recessed portion 31a1 that is recessed on the side opposite to the frame 40 side. If the recessed portion 31a1 is formed, the recessed portion 31a1 becomes an insect pocket, and dead insects and foreign substances accumulate in the recessed portion 31a1. be. Therefore, it is not necessary to form the concave portion 31a1 in each protruding portion 31a. In this case, for example, even if the shape of the XZ cross section of the protruding portion 31a is V-shaped, and the ceiling side portion of the protruding portion 31a is formed in the same plane as the first clamping piece 32a of the mounting portion 32. good.

The attachment portion 32 is a portion attached to the frame 40 . Specifically, the attachment portion 32 is attached to an end portion of the frame 40 in the lateral direction (width direction). The attachment portion 32 includes an extension portion extending from the cover body portion 31 toward the ceiling.

In the present embodiment, the mounting portions 32 are provided at both ends of the frame 40 in the lateral direction. That is, the cover member 30 has a pair of mounting portions 32 .

The pair of mounting portions 32 are provided on the cover body portion 31 . Specifically, the pair of mounting portions 32 are formed as a pair of leg portions so as to stand from both ends of the cover body portion 31 in the short direction (X-axis direction) of the cover body portion 31 . . Therefore, the pair of mounting portions 32 protrude from the cover body portion 31 toward the ceiling. In addition, as shown in FIG. 7, each of the pair of mounting portions 32 is elongated along the Y-axis direction. The length of the pair of mounting portions 32 in the Y-axis direction is the same, but the length is not limited to this.

As shown in FIGS. 3 and 6, the mounting portion 32 has a first clamping piece 32a and a second clamping piece 32b as a pair of clamping pieces that clamp the ends of the frame 40 in the lateral direction. Therefore, the ends of the frame 40 in the lateral direction are located between the first clamping piece 32a and the second clamping piece 32b, and are sandwiched between the first clamping piece 32a and the second clamping piece 32b. . As a result, the frame 40 is held by the mounting portion 32 while its movement in the thickness direction (Z-axis direction) is restricted. Thus, the mounting portion 32 also functions as a holding portion that holds the frame 40 .

Specifically, the mounting portion 32 has a vertical plate portion 32c extending in the Z-axis direction in addition to the first clamping piece 32a and the second clamping piece 32b. Therefore, the mounting portion 32 has a concave portion with a U-shaped cross section composed of the first clamping piece 32a, the second clamping piece 32b, and the upright plate portion 32c. The lateral ends of the frame 40 are inserted into the recesses of the mounting portion 32 . As a result, the frame 40 is restricted not only in the thickness direction (Z-axis direction) but also in the horizontal direction (X-axis direction).

The first clamping piece 32a and the second clamping piece 32b are plate pieces having a uniform thickness. Among the first clamping piece 32a and the second clamping piece 32b, the first clamping piece 32a is a plate piece positioned on the floor side, and the second clamping piece 32b is a plate piece positioned on the ceiling side.

The first clamping piece 32 a and the second clamping piece 32 b are provided on each of the pair of mounting portions 32 . Therefore, both ends of the frame 40 in the lateral direction are held by the first clamping piece 32 a and the second clamping piece 32 b of each of the pair of mounting portions 32 . Specifically, each of the lateral end portions of the frame 40 has a U-shaped cross section composed of a first clamping piece 32a, a second clamping piece 32b, and an upright plate portion 32c at each mounting portion 32. inserted into the recess.

In each mounting portion 32, both the first clamping piece 32a and the second clamping piece 32b do not necessarily have to be in contact with the ends of the frame 40 in the lateral direction. Specifically, only one of the first clamping piece 32a and the second clamping piece 32b may be in contact with the end of the frame 40 in the lateral direction. For example, when the LED lighting fixture 1 is installed on the ceiling, as shown in FIG. Only one clamping piece 32a may be in contact with the end of the frame 40 in the lateral direction. In this case, the floor-side first clamping piece 32 a functions as a stopper that supports the frame 40 . That is, the pair of first clamping pieces 32a on the floor side support the ends of the frame 40 in the short direction so that the frame 40 does not shift toward the light emitting side (floor side) of the LED 20 .

The first clamping piece 32a and the second clamping piece 32b are erected from the upright plate portion 32c inside the upright plate portion 32c. Specifically, the first clamping piece 32a and the second clamping piece 32b are formed to protrude in the X-axis direction and extend in the X-axis direction. The first clamping piece 32a and the second clamping piece 32b are formed in parallel.

In the present embodiment, in each mounting portion 32, the lengths in the X-axis direction of the first clamping piece 32a and the second clamping piece 32b are the same. Also, the lengths in the X-axis direction of the pair of first clamping pieces 32a in the pair of mounting portions 32 are the same, and the lengths in the X-axis direction of the pair of second clamping pieces 32b in the pair of mounting portions 32 are also the same. be. The first clamping piece 32a and the second clamping piece 32b in each of the pair of mounting portions 32 are provided at the same height position in the Z-axis direction. Therefore, the two first clamping pieces 32a and the two second clamping pieces 32b in the lateral direction of the cover member 30 are bilaterally symmetrical.

Further, as shown in FIG. 7, the first clamping piece 32a and the second clamping piece 32b of each mounting portion 32 are formed in an elongated shape along the Y-axis direction. Also, the lengths in the Y-axis direction of the first clamping piece 32a and the second clamping piece 32b are the same. As an example, the first clamping piece 32a and the second clamping piece 32b have the same shape and the same length, but this is not restrictive. Although the vertical plate portions 32c of the pair of mounting portions 32 have the same length in the Z-axis direction, the present invention is not limited to this.

The mounting portion 32 configured in this manner also has a function of preventing insects from entering the space between the cover member 30 and the frame 40 . For example, contact between the first clamping piece 32 a and the frame 40 can prevent insects from entering through a gap between the first clamping piece 32 a of the cover member 30 and the frame 40 . This can prevent insects from entering the space between the cover body 31 of the cover member 30 and the frame 40 .

The cover member 30 is made of a translucent resin material such as acrylic or polycarbonate or a translucent material such as a glass material. In this embodiment, the cover member 30 is made of translucent resin material. In this case, the cover member 30 can be a milky white cover member in which the light diffusion material is dispersed. Such a cover member 30 can be produced by molding a translucent resin material mixed with a light diffusing material into a predetermined shape. Light reflective fine particles such as silica particles can be used as the light diffusing material.

The cover member 30 is formed by forming a milky-white light diffusion film containing a light diffusion material on the surface (inner surface or outer surface) of the transparent cover instead of dispersing the light diffusion material inside. good too. Further, the cover member 30 may be configured to have light diffusibility by performing diffusion processing instead of using a light diffusion material. For example, the cover member 30 may be subjected to surface treatment such as embossing to form fine irregularities on the surface of the transparent cover, or may be printed with a dot pattern on the surface of the transparent cover so as to have light diffusion properties. may be configured. Even when the cover member 30 is processed for diffusion, it may further contain a light diffusing material in order to enhance the light diffusibility.

In this embodiment, the cover main body portion 31 and the mounting portion 32 that constitute the cover member 30 are integrally formed. Therefore, the cover body portion 31 and the mounting portion 32 are made of the same material.

Note that the cover member 30 may be made of two or more kinds of resin materials instead of one kind of resin material. For example, the cover main body portion 31 and the attachment portion 32 may be made of different resin materials. As an example, the cover body portion 31 can be made of a translucent resin material, and the attachment portion 32 can be made of a white resin material. In this case, the cover member 30 can be formed by two-color molding.

The frame 40 is an elongated support member (base member) that supports the substrate 10 . The substrate 10 is attached to the frame 40 . Specifically, the substrate 10 is supported by the frame 40 by placing the substrate 10 on the frame 40 and fixing the substrate 10 to the frame 40 . In this embodiment, the frame 40 supports not only the substrate 10 but also the cover member 30 . Specifically, the cover member 30 is fixed to the frame 40 .

The frame 40 is made of sheet metal and configured by a metal plate. The frame 40 is formed into a predetermined shape by subjecting, for example, one sheet metal (metal plate) made of SPCC (Steel Plate Cold Commercial) to roll forming or press working.

As shown in FIGS. 3 to 7, the frame 40 has a main plate portion as a portion formed in a flat plate shape as a whole. In this embodiment, the frame 40 is composed only of the main plate portion, and all or most of the frame 40 is formed in a flat plate shape. Specifically, the frame 40 is substantially I-shaped in the XZ cross section. Therefore, the frame 40 does not have a pair of side plate portions extending toward the ceiling like a conventional frame having a substantially U-shaped cross section, and has a thin shape with a low height in the Z-axis direction. It has become. The frame 40 is elongated in the Y-axis direction, like the substrate 10 and the device main body 2 .

The thickness of the metal plate forming the frame 40 is, for example, 0.2 mm to 2 mm. In the present embodiment, the frame 40 is formed by sheet metal processing, so the thickness of the metal plate forming the frame 40 is preferably 1 mm or less. Specifically, the thickness of the metal plate forming the frame 40 was set to 0.5 mm.

The board 10 on which the LEDs 20 are mounted is arranged on the frame 40 . Specifically, the substrate 10 is arranged on a portion (main plate portion) of the frame 40 that is formed in a flat plate shape as a whole. The substrate 10 is placed on the floor-side surface of the frame 40 . The second surface 10b of the substrate 10 and the floor-side surface of the frame 40 are in surface contact.

With respect to the frame 40, the direction of the side of the frame 40 where the board 10 is arranged is defined as the front (first direction), and the direction opposite to the front is defined as the rear (second direction). In terms of form, the front side of the frame 40 is the floor side (cover member 30 side), and the rear side of the frame 40 is the ceiling side (back side).

The substrate 10 is attached to a portion (main plate portion) of the frame 40 that is formed in a flat plate shape as a whole. For example, the substrate 10 is fixed to the frame 40 by claws formed on the frame 40 . The claw portion can be formed by cutting and raising a part of the frame 40 made of sheet metal. The substrate 10 placed on the frame 40 is fixed to the frame 40 by bending the claw portion and engaging the claw portion. Further, the frame 40 is provided with through holes through which conductive wires for electrically connecting the electrodes of the substrate 10 and the power supply device 4 are inserted.

A flat plate-shaped frame 40 as a whole is arranged so as to be parallel to the ceiling. Specifically, the plate-shaped frame 40 is arranged so that the substrate 10 arranged on the frame 40 is parallel to the ceiling.

As shown in FIGS. 3 and 7, a portion (main plate portion) of the frame 40 that is formed in a flat plate shape as a whole includes at least a reinforcing portion 41 of a ridge linearly formed along the longitudinal direction of the frame 40. have one. That is, the reinforcing portion 41 of the ridge is formed to protrude from the main surface of the main plate 40M in a cross-sectional view, and is formed to extend linearly and slenderly. The reinforcing portion 41 can be formed by press working such as beading or embossing. In the present embodiment, the reinforcing portion 41 is formed by subjecting the metal plate forming the frame 40 to bead processing (stringing processing). Specifically, the reinforcing portion 41 can be formed by deforming the metal plate in the thickness direction by pushing up the metal plate to one side in the thickness direction using a mold or the like. The reinforcing portion 41 formed in this manner includes a linear convex portion formed on one surface of the metal plate and a linear convex portion formed on the other surface of the metal plate at a position opposite to the convex portion. It is composed of a linear concave portion. That is, the thickness of the metal plate in the reinforcing portion 41 and the thickness of the metal plate without the reinforcing portion 41 are basically the same. By forming the reinforcing portion 41 in the frame 40 in this manner, the rigidity of the frame 40 can be increased. That is, the reinforcing portion 41 functions as a reinforcing rib for increasing mechanical strength.

The cross-sectional shape of the reinforcing portion 41 is, for example, a part of a circle, and is semicircular in the present embodiment. That is, both the outer shape of the convex portion of the reinforcing portion 41 and the inner shape of the reinforcing portion 41 are semicircular.

The reinforcing portion 41 is formed from one longitudinal end of the frame 40 to the other longitudinal end. Note that the reinforcing portion 41 may be intermittently formed along the longitudinal direction of the frame 40 .

A plurality of reinforcing portions 41 are formed on the frame 40 . A plurality of reinforcing portions 41 are formed in parallel. In the present embodiment, the plurality of reinforcing portions 41 are formed on both sides of the frame 40, and include a first reinforcing portion 41a protruding forward (floor side) and a second reinforcing portion 41a protruding rearward (ceiling side). and a reinforcing portion 41b. Two first reinforcements 41a and two second reinforcements 41b are provided. That is, four reinforcing portions 41 are provided.

As shown in FIG. 7 , both longitudinal end portions of the first reinforcing portion 41 a are located at positions recessed from the longitudinal end edges of the frame 40 . That is, the first reinforcing portion 41a is not formed up to the edge of the frame 40 in the longitudinal direction. On the other hand, the longitudinal ends of the second reinforcing portions 41b are formed up to the longitudinal edges of the frame 40 . Both longitudinal ends of the first reinforcing portion 41a are formed to the longitudinal edges of the frame 40, and both longitudinal ends of the second reinforcing portion 41b are not formed to the longitudinal edges of the frame 40. can be Alternatively, both longitudinal ends of the first reinforcing portion 41a and both longitudinal ends of the second reinforcing portion 41b may be formed up to the longitudinal edges of the frame 40, or both of the longitudinal ends of the frame 40 may be formed. It is also possible not to form up to the edges in the longitudinal direction of the .

The width of the convex portion of the reinforcing portion 41 is, for example, 10 mm or less to 5 mm or less, and is about 3 mm in the present embodiment. Moreover, the height of the convex portion of the reinforcing portion 41 is, for example, 5 mm or less. In the present embodiment, the width and height of the convex portions in each of the plurality of reinforcing portions 41 are all the same, but the present invention is not limited to this. In addition, although the cross-sectional shapes of the plurality of reinforcing portions 41 are all the same, the cross-sectional shape is not limited to this.

The substrate 10 arranged on the frame 40 is positioned between two adjacent reinforcing portions 41 among the plurality of reinforcing portions 41 . Specifically, as shown in FIG. 3, the substrate 10 is positioned between the two first reinforcing portions 41a. Therefore, the distance between the two first reinforcing portions 41a is greater than the length (width) of the substrate 10 in the lateral direction. In the present embodiment, the two first reinforcing portions 41a sandwiching the substrate 10 are adjacent to the side surfaces of the substrate 10 . That is, the distance between the two first reinforcing portions 41a is substantially the same as the width of the substrate 10. As shown in FIG. Accordingly, the movement of the substrate 10 in the width direction can be restricted by the two first reinforcing portions 41a. That is, the position of the substrate 10 can be determined by the two first reinforcing portions 41a.

In particular, when the power supply device 4 and the LED module (wiring on the substrate 10) are electrically connected directly with pins without using lead wires (secondary side wiring-less structure), the accuracy is high. Although position regulation is required, by positioning the substrate 10 with the two first reinforcing portions 41a, electrical connection between the power supply device 4 and the LED module can be achieved with high accuracy even if a secondary side wiring-less structure is adopted. It can be performed.

In addition, in the plurality of reinforcing portions 41, the interval between the two second reinforcing portions 41b is smaller than the interval between the two first reinforcing portions 41a sandwiching the substrate 10 therebetween. Therefore, the two second reinforcing portions 41b are formed at positions overlapping the substrate 10 in the thickness direction (Z-axis direction) of the frame 40 . That is, the two second reinforcing portions 41b overlap the substrate 10 when viewed from above. In addition, when viewed from above, the two second reinforcing portions 41b are positioned inside the two first reinforcing portions 41a.

The ends of the frame 40 in the lateral direction (width direction) are attached to the cover member 30 . Specifically, both ends of the frame 40 in the short direction are attached to the cover member 30 . More specifically, the ends of the frame 40 in the lateral direction are sandwiched between the first pinching piece 32a and the second pinching piece 32b provided on each of the pair of mounting portions 32 of the cover member 30, so that the frame 40 are attached to the cover member 30 .

In the present embodiment, folded portions 42 provided at the ends of the frame 40 in the lateral direction are attached to the cover member 30 . That is, the folded portion 42 of the frame 40 is attached to the cover member 30 . Specifically, the folded portion 42 of the frame 40 is inserted into a concave portion of the cover member 30 which has a U-shaped cross section and is composed of the first clamping piece 32a, the second clamping piece 32b, and the upright plate portion 32c. .

The folded portion 42 is formed by folding back, in the thickness direction, the distal end portion in the width direction of the portion (main plate portion) of the frame 40 that is formed in a flat plate shape as a whole. In the present embodiment, the folded portion 42 is composed of a folded portion and a portion (non-folded portion) facing the folded portion. The folded portion of the folded portion 42 can be formed, for example, by curling the front end portion of the frame 40 in the lateral direction toward the ceiling and rolling it up. The folded portion 42 is not limited to being formed by curling, and may be formed by hemming or the like.

When fixing the cover member 30 and the frame 40, the folded portion 42 of the frame 40 is inserted between the first pinching piece 32a and the second pinching piece 32b of the cover member 30, thereby separating the first pinching piece 32a and the second pinching piece 32a. The folded portion 42 is engaged with the piece 32b. Thereby, the cover member 30 and the frame 40 can be engaged and fixed. Note that the cover member 30 and the frame 40 may be further fixed by mounting screws.

As shown in FIG. 3, a space area S is formed on the ceiling side of the frame 40 . In other words, there is a spatial region S between the fixture body 2 and the frame 40 . In this space area S, a power supply device 4 is arranged. The power supply device 4 is arranged close to one side of the frame 40 in the short direction. Specifically, the power supply device 4 is arranged closer to the side (left side in FIG. 3) where the hooking metal fitting 5 is provided.

At least one of the reinforcing portions 41 of the frame 40 is covered with the power supply device 4 arranged on the ceiling side of the frame 40 . That is, at least a portion of the reinforcing portion 41 overlaps the power supply device 4 when viewed from above. In this embodiment, all the reinforcing parts 41 are covered with the power supply device 4 . That is, the two first reinforcing portions 41a and the two second reinforcing portions 41b are covered with the power supply device 4. As shown in FIG.

Further, in the space area S on the ceiling side of the frame 40 , functional parts related to lighting of the LEDs 20 may be arranged as parts constituting the LED lighting device 3 . Such functional components are function expansion modules. The function expansion module includes, for example, a sensor unit including various sensors such as a human sensor and a brightness sensor, a wireless module including an antenna for receiving wireless signals and a control circuit, and an infrared module including a light receiving element for receiving infrared signals and a control circuit. Alternatively, it may be a second light source different from the LED 20 (first light source) mounted on the substrate 10, or the like. The radio signal or the infrared signal is, for example, a remote control signal for turning on/off the LED 20 or adjusting the light/color, or a setting signal for making various settings of the LED lighting device 3 . The second light source includes a light source for monitor display, a light source for controlling the light distribution of the illumination light emitted from the cover member 30 (for example, a light source for wide light distribution), and a color light source for rendering (for example, , red, blue and green LED light sources), or an emergency light source that lights up in an emergency. When using an emergency light source as the second light source, the cover and/or the cover member 30 covering the second light source may be made of a flame-retardant material such as glass. Also, the functional component may be part of the power supply device 4 .

The functional components arranged in the spatial region S and the power supply device 4 are electrically connected by conductive lines. The conductive wire is one of the components that make up the LED lighting device 3 . Conductive lines are arranged in the spatial region S together with the functional components. In other words, the conductive wires connected to the functional parts are accommodated in the spatial region S together with the power wires connected to the power supply device 4 . Note that the space area S also accommodates the elastic holding member 6 shown in FIG.

A long cylindrical body is configured by fixing the cover member 30 and the frame 40 . As shown in FIGS. 1 to 5, end caps 50 are attached to both ends in the longitudinal direction of the tubular body composed of the cover member 30 and the frame 40 .

That is, the end cap 50 is attached to the cylindrical body so as to cover the open end of the cylindrical body composed of the cover member 30 and the frame 40, and closes the open end of the cylindrical body. As a result, it is possible to prevent dust, insects, and the like from entering the cylindrical body composed of the cover member 30 and the frame 40 . Even if the end cap 50 does not completely close the opening end of the cylindrical body composed of the cover member 30 and the frame 40 and there is a slight gap between the end cap 50 and the frame 40, good.

The end caps 50 are provided at both ends of the cover member 30 in the longitudinal direction. That is, the end cap 50 is a cover end provided at the end of the cover member 30 . The end caps 50 are directly or indirectly connected to the longitudinal ends of the cover member 30 . For example, the end cap 50 and the cover member 30 are fixed with an adhesive.

The end cap 50 is made of a resin material. Also, the end cap 50 may or may not have translucency. The translucent end cap 50 is made of, for example, a transparent resin material such as polycarbonate or acrylic. Also, the end cap 50 may have translucency and diffusivity. In this case, the end cap 50 may be made of the same material as the cover member 30 or may be made of a different material from the cover member 30 .

The LED lighting device 3 configured in this manner is housed in the concave portion 2 a of the fixture body 2 and attached to the fixture body 2 . Specifically, the LED lighting device 3 is attached to the fixture main body 2 using the hook fitting 5 and the elastic holding member 6 shown in FIGS. The hook fitting 5 and the elastic holding member 6 are fixed to the frame 40 .

As shown in FIG. 3 , the hook 5 is arranged on the rear side (ceiling side) of the frame 40 . The hook 5 is a plate member made of sheet metal. The hook 5 is fixed to one end of the frame 40 in the short direction. As an example, the hook fitting 5 is fixed to the frame 40 by a fixing member such as a screw, and extends outward from the frame 40 . The hook fitting 5 is hooked on the instrument body 2. - 特許庁In this embodiment, a slit 2c (see FIG. 2) is provided in the inner wall surface of the concave portion 2a of the instrument main body 2, and the hook 5 is hooked on this slit 2c.

The elastic holding member 6 is arranged on the rear side (ceiling side) of the frame 40 . The elastic holding member 6 is, for example, a spring such as a kick spring. The elastic holding member 6 is fixed to the other end of the frame 40 in the short direction. That is, the elastic holding member 6 is fixed on the opposite side of the frame 40 from the hook 5 in the width direction. The elastic holding member 6 is fixed to the frame 40 with a fixing member such as a screw. Specifically, the elastic holding member 6 is fixed to a holding metal fitting 6c (see FIG. 5) fixed to the frame 40 by means of mounting screws. The elastic holding member 6 is detachably attached to the instrument body 2 . In this embodiment, the elastic holding member 6 is detachably locked to a receiving metal fitting 7 fixed to the instrument main body 2 .

In addition, as shown in FIG. 2, two hook fittings 5 and two elastic holding members 6 are provided, but the present invention is not limited to this. Moreover, although the hook fitting 5 and the elastic holding member 6 are provided at positions opposed to each other in the lateral direction of the frame 40, the present invention is not limited to this.

Here, a method for attaching the LED lighting device 3 to the fixture main body 2 will be described with reference to FIG. 8 . 8A and 8B are diagrams for explaining a mounting method for mounting the LED lighting device 3 to the fixture body 2 in the LED lighting fixture 1 according to Embodiment 1. FIG.

When attaching the LED lighting device 3 to the fixture body 2 installed on the ceiling 100, first, as shown in FIG. By hooking, the LED lighting device 3 is suspended in a cantilevered state, and one end of the elastic holding member 6 which is a kick spring is engaged with the receiving metal fitting 7 fixed to the fixture main body 2 .

At this time, since the frame 40 has a flat plate shape as a whole and does not have a side plate portion extending rearward, the length in the Z-axis direction of the attachment portion 32 of the cover member 30 attached to the frame 40 can be shortened. can. Therefore, when the LED lighting device 3 is viewed from the side, a large portion of the elastic holding member 6 is exposed. Can be pulled out easily.

Next, as shown in FIG. 8(b), the LED lighting device 3 is rotated around the hooking metal fitting 5 as a fulcrum while the hooking metal fitting 5 is pushed into the slit 2c, thereby moving the LED lighting device 3 into the concave portion of the fixture main body 2. Next, as shown in FIG. Push up into 2a.

At this time, in the present embodiment, the power supply device 4 arranged on the back side of the frame 40 is arranged closer to the hooking metal fitting 5 side. That is, the power supply device 4 is arranged close to the rotating shaft side. In this way, by arranging the heavy power supply device 4 close to the rotation shaft side, the LED lighting device 3 can be rotated with a small force.

Then, by rotating the LED lighting device 3 and pushing the LED lighting device 3 into the recess 2a of the fixture body 2, the LED lighting device 3 is fitted into the recess 2a of the fixture body 2 as shown in FIG. can enter. Thereby, the LED lighting device 3 can be attached to the fixture main body 2 .

When removing the LED lighting device 3 from the fixture main body 2, the LED lighting device 3 can be removed from the fixture main body 2 by performing an operation opposite to that described above.

As described above, when the LED lighting device 3 is attached to and detached from the fixture main body 2, since the LED lighting device 3 in the present embodiment uses the frame 40 formed in a flat plate shape as a whole, the LED lighting device 3 and the device main body 2 are prevented from being damaged, and the conductive wires routed to the rear side of the frame 40 are prevented from being bitten. This point will be described below.

Since the conventional frame is provided with a side plate portion extending toward the ceiling, when the LED lighting device having this frame is attached to the fixture body 2, the side plate portion of the frame may come into contact with the fixture body 2 or the side plate may be damaged. The side plate portion of the cover member attached to the part may hit the instrument body 2 and damage an unintended location.

On the other hand, in the LED lighting device 3 according to the present embodiment, the frame 40 has a flat plate shape as a whole, and the frame 40 has no side plate portion extending toward the ceiling. Therefore, the overall thickness of the frame 40 is reduced, and as a result, the overall thickness of the cover member 30 attached to the frame 40 is also reduced. A portion or a portion of the cover member 30 can be prevented from hitting the instrument main body 2 . In other words, it is possible to prevent damage to unintended portions of the LED lighting device 3 or the fixture body 2 during installation.

In addition, if the side plate portion extends toward the ceiling side as in the conventional frame, the conductive wires such as power lines or signal lines routed to the ceiling side (rear side) of the frame may There is a risk of being caught between the part and the device main body 2 or between the side plate portion of the cover member attached to the side plate portion of the frame and the device main body 2 . In other words, there is a risk that the conductive wires will be jammed.

On the other hand, in the LED lighting device 3 according to the present embodiment, the frame 40 has a flat plate shape as a whole, and the frame 40 does not have a side plate portion extending long toward the ceiling side. It is possible to prevent the conductive wire arranged on the ceiling side from being caught between a part of the frame 40 and the instrument body 2 or between a part of the cover member 30 and the instrument body 2. - 特許庁That is, it is possible to suppress the occurrence of wire biting of the conductive wires.

In this way, by using the LED lighting device 3 according to the present embodiment, the LED lighting device 3 and the fixture main body 2 may be damaged, or the conductive wires routed to the rear side of the frame 40 may be jammed. can be suppressed. Therefore, the LED lighting device 3 can be easily attached to the fixture main body 2 . That is, the workability of the LED lighting fixture 1 is improved.

In addition, the frame 40 in the present embodiment has a flat plate shape as a whole, and does not have a side plate portion extending toward the ceiling, unlike a conventional frame. Therefore, it is not necessary to provide the side plate portion for covering the side plate portion of the frame in the cover member attached to the frame. That is, the cover member 30 attached to the frame 40 also does not have a side plate portion extending rearward. Thereby, as shown in FIG. 3, the space area S on the ceiling side of the frame 40 can be widened. Therefore, it is possible to widen the wiring space for arranging conductive wires such as power wires arranged on the ceiling side (rear side) of the frame 40 .

As described above, according to the LED lighting fixture 1 and the LED lighting device 3 according to the present embodiment, while securing a wide wiring space on the rear side of the frame 40, the LED lighting fixture 1 can be installed in the rear of the frame 40. It is possible to suppress the wire biting of the conductive wires arranged on the side.

Furthermore, by using the frame 40 formed in a flat plate shape as a whole, even if the cover member 30 is attached to the frame 40, the height (thickness) of the cylindrical body formed by the frame 40 and the cover member 30 can be reduced. can do. That is, the height (thickness) of the LED lighting device 3 can be reduced, and the height of the LED lighting device 3 can be reduced. This makes it possible to easily attach and detach the LED lighting device 3 to and from the fixture main body 2 .

Moreover, by using the flat plate-shaped frame 40 in which the side plate portion extending toward the ceiling side is not formed, the weight of the frame 40 can be reduced, and the material cost and processing cost can be reduced. Therefore, the cost of the frame 40 can be reduced. Therefore, it is also possible to reduce the weight and cost of the LED lighting device 3 .

However, the frame 40 not provided with a pair of side plate portions as in the present embodiment has a mechanical strength lower than that of a conventional frame having a U-shaped cross section provided with a pair of side plate portions. it gets lower. Therefore, the frame 40 according to the present embodiment is easily deformed by bending or warping. As a result, even if the cover member 30 is attached to the frame 40 according to the present embodiment, compared to the case of using the conventional frame provided with the side plate portions, the cylinder formed by the frame 40 and the cover member 30 can be Low body stiffness. Therefore, the frame 40 may be deformed during construction or the like.

Therefore, in the LED lighting fixture 1 and the LED lighting device 3 according to the present embodiment, a portion (main plate portion) of the frame 40 to which the substrate 10 is attached is linearly formed along the longitudinal direction of the frame 40. A reinforcing portion 41 of the ridge is formed.

By forming the reinforcing portion 41 in the portion (main plate portion) of the frame 40 to which the substrate 10 is attached in this way, even if the portion (main plate portion) of the frame 40 to which the substrate 10 is attached is flat as a whole, the frame 40 can be suppressed from decreasing in strength. In other words, by forming the reinforcing portion 41 in the frame 40, the strength of the frame 40, which has been lowered by making the entire frame 40 flat, can be increased. Thereby, deformation of the frame 40 can be suppressed. Therefore, since the rigidity of the LED lighting device 3 can be increased, deformation of the LED lighting device 3 can be suppressed.

As described above, according to the LED lighting fixture 1 and the LED lighting device 3 according to the present embodiment, even if the portion of the frame 40 to which the substrate 10 is attached is formed into a flat plate as a whole, the frame 40 is deformed. can be suppressed. Therefore, by using the frame 40 which is formed in a flat plate shape as a whole, a wide wiring space can be secured on the rear side of the frame 40, and the wire jamming of the conductive wires arranged on the rear side of the frame 40 can be suppressed. , and deformation of the frame 40 can be suppressed. In other words, it is possible to secure a wide wiring space on the rear side of the frame 40, suppress the wire jamming of the conductive wires, and suppress the deformation of the frame 40 at the same time.

Moreover, as shown in FIG. 9 , the LED lighting fixture 1 and the LED lighting device 3 according to the present embodiment further include a reinforcing member 60 . FIG. 9 is a cross-sectional view of the LED lighting fixture 1 according to Embodiment 1, showing a cross-section taken along a plane passing through the reinforcing member 60. FIG.

A reinforcing member 60 supports the frame 40 . In this embodiment, reinforcing member 60 also supports cover member 30 . The reinforcing member 60 is fixed to the frame 40 by, for example, mounting screws 70 . Note that the reinforcing member 60 and the frame 40 may be fixed by a method other than the mounting screws 70 . For example, the reinforcing member 60 and the frame 40 may be fixed by crimping a portion of the reinforcing member 60 and a portion of the frame 40 .

The reinforcing member 60 is, for example, a metal fitting formed into a predetermined shape by applying sheet metal processing to a metal plate. In the present embodiment, the reinforcing member 60 has a shape formed along the shape of the rear side (ceiling side) of the LED lighting device 3 . Specifically, the reinforcing member 60 is formed along the ceiling-side surface of the second holding piece 32 b of the cover member 30 and along the ceiling-side surface of the frame 40 .

The LED lighting device 3 may have one reinforcing member 60 or may have a plurality of reinforcing members 60 . As shown in FIG. 5, the LED lighting device 3 includes three reinforcing members 60 in this embodiment. In this case, reinforcing members 60 are arranged at both ends and the central portion of the LED lighting device 3 in the longitudinal direction.

The reinforcing member 60 may be part of a metal fitting attached to the LED lighting device 3, such as the holding metal fitting 6c. Further, the central reinforcement member 60 may be a part of the circuit case 4 c that constitutes the power supply device 4 .

By supporting the frame 40 with the reinforcing member 60 in this manner, deformation of the frame 40 can be further suppressed. Moreover, since the frame 40 is supported from the rear side by the reinforcing member 60 , it is possible to prevent the frame 40 from coming off the cover member 30 .

Further, the frame 40 in the present embodiment has a thin plate shape as a whole and has a substantially I-shaped cross section. Therefore, the frame 40 can be used upside down. Specifically, in FIG. 3, two convex first reinforcements 41a with a wide interval are located on the floor side, and two convex second reinforcements 41b with a narrow interval are located on the ceiling side. However, as in the LED lighting fixture 1A and the LED lighting device 3A shown in FIG. 10, the same frame as the frame 40 shown in FIG. The frame 40 may be arranged such that the first reinforcing portion 41a is located on the ceiling side, and the two closely spaced convex second reinforcing portions 41b are located on the floor side.

In this case, the substrate 10A arranged on the floor side surface of the frame 40 is arranged between the two second reinforcing portions 41b with a narrow interval, so that the substrate 10A is narrower than the substrate 10 shown in FIG. is used.

In this way, the frame 40 can be turned upside down and used, so that the interval between the two reinforcing portions 41 forming the convex portions on the floor side surface of the frame 40 can be widened or narrowed. Thereby, between the two reinforcing parts 41, it is possible to arrange the substrate 10 having a wide width or to arrange the substrate 10A having a narrow width. At this time, when using a substrate 10A with a narrow width, the substrate 10A on which only one row of LEDs 20 emitting light with the same color temperature is arranged is used, and when using a substrate 10 with a wide width, different A substrate 10 in which LEDs 20 emitting light of a color temperature are arranged in two rows can be used. Thereby, a plurality of types of LED lighting devices 3 can be realized using one frame 40 . For example, the non-dimming type LED lighting device 3 and the dimming type LED lighting device 3 can be manufactured with one frame 40 only by turning the frame 40 upside down.

Note that instead of inverting the frame 40 upside down, two convex second reinforcing parts 41b with a wide interval are positioned on the ceiling side like the LED lighting fixture 1B and the LED lighting device 3B shown in FIG. In addition, a frame 40B may be used in which two convex first reinforcing portions 41a with a narrow interval are positioned on the floor side. Also, the frame 40B may be arranged upside down. When the frame 40B is turned upside down, the wide board 10 shown in FIG. 3 can be placed on the frame 40B.

In addition, in the LED lighting fixture 1 and the LED lighting device 3 shown in FIG. 3 , the frame 40 is formed with two first reinforcing portions 41a and two second reinforcing portions 41b as the plurality of reinforcing portions 41. However, the numbers of the first reinforcing portions 41a and the two second reinforcing portions 41b are not limited to this.

For example, as in the LED lighting fixture 1C and the LED lighting device 3C shown in FIG. may be used. In this case, the second reinforcing portion 41b is preferably formed in the central portion in the lateral direction of the frame 40C. Moreover, the second reinforcing portion 41b is preferably formed at a position overlapping the LED 20 in top view.

Also, as in the LED lighting fixture 1D and the LED lighting device 3D shown in FIG. 13, a frame 40D in which only two second reinforcing portions 41b are formed may be used as the plurality of reinforcing portions 41. FIG. That is, a frame 40D in which the first reinforcing portion 41a is not formed may be used. In this case, a frame 40E in which only one second reinforcing portion 41b is formed may be used like the LED lighting fixture 1E and the LED lighting device 3E shown in FIG. In other words, the number of reinforcing portions 41 is not limited to plural, and may be one.

At least one reinforcing portion 41 may be formed like this frame 40E. Thereby, the strength of the frame 40E can be effectively improved.

(Embodiment 2)
Next, Embodiment 2 will be described with reference to FIG. 15 . FIG. 15 is a cross-sectional view of an LED lighting fixture 1F according to Embodiment 2. FIG.

The LED lighting fixture 1F and the LED lighting device 3F according to the present embodiment have a configuration in which a joint portion 80 is provided between the frame 40 and the substrate 10 in the LED lighting fixture 1 and the LED lighting device 3 shown in FIG. It has become.

The joint portion 80 is a joint member that joins the substrate 10 and the frame 40 . By providing the bonding portion 80 between the substrate 10 and the frame 40 in this way, the adhesion between the substrate 10 and the frame 40 is improved.

In this embodiment, the joint 80 is an adhesive made of an insulating resin material. In this case, it is preferable to use a material having excellent thermal conductivity as the joint portion 80 . As a result, the heat generated by the LEDs 20 can be efficiently conducted to the frame 40, so that the heat dissipation performance of the heat generated by the LEDs 20 can be improved.

Note that the bonding portion 80 is not limited to an adhesive, and may be double-sided tape or the like. Can be absorbed by glue. Moreover, by using an adhesive as the joint 80, the adhesive can be filled without forming a gap between the substrate 10 and the frame 40, so that the heat generated by the LED 20 can be effectively dissipated. be able to. Note that an adhesive is used as the joint 80 in the present embodiment.

As shown in FIG. 15 , in the present embodiment, the second reinforcing portion 41 b among the plurality of reinforcing portions 41 is formed at a position overlapping the substrate 10 . Therefore, the joint portion 80 inserted between the substrate 10 and the frame 40 is also provided in the concave portion of the second reinforcing portion 41b. In the present embodiment, the joint portion 80 fills the concave portion of the second reinforcing portion 41b, but the concave portion of the second reinforcing portion 41b may not be filled.

As described above, in the LED lighting fixture 1F and the LED lighting device 3F according to the present embodiment, as in the first embodiment, the frame 40 is made of a metal plate formed in a flat plate shape as a whole. The frame 40 has at least one ridge reinforcing portion 41 linearly formed along the longitudinal direction of the frame 40 .

As a result, the same effects as those of the LED lighting fixture 1 and the LED lighting device 3 according to the first embodiment are obtained. Specifically, by using the frame 40 in which the portion (main plate portion) to which the substrate 10 is attached is formed in a flat plate shape as a whole, a wide wiring space can be secured on the rear side of the frame 40, and the rear side of the frame 40 can be In addition, even if the frame 40 formed in a flat plate shape as a whole is used, the frame 40 is reinforced with the reinforcing portion 41, so that deformation of the frame 40 can be prevented. can be suppressed.

Furthermore, in this embodiment, a joint 80 is provided between the frame 40 and the substrate 10 . As a result, the adhesion between the frame 40 and the substrate 10 can be improved, so that the heat dissipation property of the heat generated by the LEDs 20 can be improved.

Moreover, in the present embodiment, the joint portion 80 is provided in the concave portion of the second reinforcing portion 41 b formed at a position overlapping the substrate 10 . Thereby, the bonding strength between the frame 40 and the substrate 10 can be improved.

Further, by arranging the substrate 10 overlapping the recessed portion of the second reinforcing portion 41b, the substrate 10 is joined to the frame 40 by applying an adhesive that forms the joining portion 80 between the substrate 10 and the frame 40. Since the excess adhesive can escape to the concave portion of the second reinforcing portion 41b, the substrate 10 may be lifted by the excess adhesive, or uneven distribution of the adhesive may cause unevenness in the thickness of the joint portion 80. It is possible to suppress the occurrence of tilting of the substrate 10 . That is, since the adhesive can escape to the concave portion of the second reinforcing portion 41b, the amount of the adhesive that protrudes can be easily managed.

In this embodiment, the configuration is such that the joint portion 80 is added to the LED lighting fixture 1 and the LED lighting device 3 shown in FIG. 3, but the present invention is not limited to this.

For example, like an LED lighting fixture 1G and an LED lighting device 3G shown in FIG. 16, a configuration in which a joint portion 80 is added to the LED lighting fixture 1C and the LED lighting device 3C shown in FIG. 12 may be used. That is, in the LED lighting device 3C using the frame 40C in which the two first reinforcing portions 41a and one second reinforcing portion 41b are formed as the reinforcing portions 41, the joint portion 80 is formed between the frame 40C and the substrate 10. may be provided.

Alternatively, like the LED lighting fixture 1H and the LED lighting device 3H shown in FIG. 17, a configuration in which a joint portion 80 is added to the LED lighting fixture 1D and the LED lighting device 3D shown in FIG. 13 may be used. That is, in the LED lighting device 3D using the frame 40D in which only the two second reinforcing portions 41b are formed as the reinforcing portion 41, the joint portion 80 may be provided between the frame 40D and the substrate 10.

Note that the joint portion 80 may be added to other embodiments.

(Modification)
As described above, the LED lighting fixture and the LED lighting device according to the present invention have been described based on the first and second embodiments, but the present invention is not limited to these first and second embodiments.

For example, in Embodiments 1 and 2 described above, the folded portions 42 of the frames 40 to 40E are formed by curling the ends of the frames 40 in the lateral direction so as to fold them rearward (ceiling side). , but not limited to this. Specifically, like the LED lighting fixture 1I and LED lighting device 3I shown in FIG. It may be formed by curling. In addition, although the folded portion 42 of the frame 40 is curled so as to curve the distal end portion of the frame 40 in the lateral direction, the present invention is not limited to this. For example, like the LED lighting fixture 1J and the LED lighting device 3J shown in FIG. 19, the folded portion 42J of the frame 40J is formed by folding the distal end portion of the frame 40J in the lateral direction into a U-shaped cross section. may In this case, the folded portion 43J and the end portion of the circuit case 4c of the power supply device 4 may be engaged.

In the first embodiment, the frame 40 has only the first reinforcing portion 41a and the second reinforcing portion 41b extending in the longitudinal direction (Y-axis direction) of the frame 40 as the reinforcing portion 41. It is not limited to this. For example, like the frame 40K shown in FIG. It may have a third reinforcing portion 41z extending in the lateral direction (X-axis direction). Thereby, the strength of the frame 40K can be further improved. Further, by providing the third reinforcing portion 41c, it is possible not only to restrict the movement of the substrate 10 in the width direction, but also to restrict the movement of the substrate 10 in the longitudinal direction. Therefore, positioning of the substrate 10 can be performed more easily. In particular, in the case of a secondary side wiring-less structure, it is necessary to accurately position the substrate 10 (LED module). Also, the substrate 10 (LED module) can be positioned with high accuracy. In addition, by providing the third reinforcing portion 41c to increase the strength of the frame 40K, when the cover member 30 is spread laterally and fitted into the frame 40K, the cover member 30 is spread out and the cover member 30 is spread. Member 30 and frame 40K can be easily assembled. The provision of the third reinforcing portion 41c in the frame 40K can also be applied to the frames of other embodiments.

Further, in Embodiments 1 and 2 above, the cross-sectional shape of the reinforcing portion 41 in the frames 40 to 40E is semicircular, but it is not limited to this. For example, like the frame 40L shown in FIG. 21, the reinforcing portion 41 may have a rectangular cross-sectional shape, or the reinforcing portion 41 may have a triangular cross-sectional shape like the frame 40M shown in FIG. Alternatively, as in the frame 40N shown in FIG. 23, the reinforcing portion 41 may have a trapezoidal cross-sectional shape.

Moreover, in Embodiments 1 and 2, the lengths in the X-axis direction of the first clamping piece 32a and the second clamping piece 32b in the mounting portion 32 of the cover member 30 are the same, but the present invention is not limited to this. For example, like the mounting portion 32O of the cover member 30O in the LED lighting fixture 1O and the LED lighting device 3O shown in FIG. good. As a result, when the cover member 30O is laterally spread and fitted into the frame 40, the cover member 30O is hit in the spread state, so that the cover member 30O and the frame 40 can be easily assembled. Moreover, since the first clamping piece 32a on the floor side is long, the frame 40 comes into contact with the first clamping piece 32a and stops when the frame 40 is inserted from above. can. Further, by using a different material (for example, a white material) for the longer first clamping piece 32a and manufacturing the cover member 30O by two-color molding, the white coating of the frame 40 can be eliminated, and the cover member 300 can be Light loss due to the member 30O can be reduced.

Alternatively, like the mounting portion 32P of the cover member 30P in the LED lighting fixture 1P and the LED lighting device 3P shown in FIG. good. As a result, even if the cover member 30P is spread out, the cover member 30P is unlikely to come off, so it is possible to prevent the cover member 30P from coming off when the LED lighting device 1P is used. Furthermore, since the floor-side first clamping piece 32a is short, light loss due to the cover member 30P can be reduced.

Further, in Embodiments 1 and 2 described above, the frame 40 is positioned near the opening surface of the opening of the lighting fixture 2, but the present invention is not limited to this. For example, like the LED lighting fixture 1Q and the LED lighting device 3Q shown in FIG. can be configured to This makes it possible to increase the distance between the LEDs 20 arranged on the substrate 10 attached to the frame 40 and the cover main body portion 31 of the cover member 30Q, thereby suppressing unevenness in luminance (feeling of crushing) due to the light of the LEDs 20. It is possible to improve luminance uniformity in the cover member 30Q. Moreover, since the temperature rise of LED20 can be suppressed by lengthening the distance of LED20 and the cover main-body part 31, the luminous efficiency of LED20 can be improved.

Alternatively, as in the LED lighting fixture 1R and the LED lighting device 3R shown in FIG. Alternatively, the frame 40 may be positioned closer to the floor than the opening of the appliance body 2 . Thereby, the wiring space inside the device body 2 can be increased. Further, by adopting the structure of the LED lighting fixture 1R shown in FIG. 27, the width of the frame 40 can be made larger than the width of the opening of the fixture main body 2. As shown in FIG. Furthermore, since the frame 40 can be brought into contact with the opening of the instrument main body 2 via the mounting portion 32 of the cover member 30R, positioning can be easily performed.

Moreover, in the first and second embodiments, the entire substrate 10 is in contact with the frame 40, but the present invention is not limited to this. Specifically, like the LED lighting fixture 1S and the LED lighting device 3S shown in FIG. 28, the frame 40S is formed with the opening 40a, and the second surface 10b of the substrate 10 is partly the opening of the frame 40S. It may be configured to be exposed from the portion 40a. In this case, instead of bringing the second surface 10b of the substrate 10 into contact with the outer surface of the frame 40S, the first surface 10a of the substrate 10A is placed in the frame as in the LED lighting fixture 1T and the LED lighting device 3T shown in FIG. It may be brought into contact with the inner surface of 40S. In other words, the substrate 10A may be arranged inside the frame 40S instead of outside. Further, when the substrate 10A is arranged inside the frame 40S, a support member 90 for supporting the substrate 10a may be separately arranged as in the LED lighting fixture 1U and the LED lighting device 3U shown in FIG. As the frame 40S in which the opening 40a is formed, one having the configuration shown in FIG. 31 can be used. Although the frame 40S shown in FIG. 31 has three openings 40a, the number of openings 40a is not limited to this. Also, the frame 40S may be composed of two parts that are separated into left and right (in the width direction).

Moreover, although the frame 40 having a substantially I-shaped cross section is used in the first and second embodiments, the configuration is not limited to this. For example, the cross-sectional shape of the frame 40 may be L-shaped or M-shaped. In addition, the frame 40 has a U-shaped or U-shaped cross-sectional shape, and includes a portion (main plate portion) formed in a flat plate shape as a whole, and a main plate portion extending from both ends in the short direction of this portion to the ceiling side. and a pair of side plate portions extending along the length of the side plate portion.

Moreover, in the first embodiment, when the LED lighting device 3 is attached to the fixture main body 2, the LED lighting device 3 is attached to the fixture main body 2 by rotating the LED lighting device 3, but the present invention is not limited to this. That is, the LED lighting device 3 may be attached to the fixture main body 2 without rotating the LED lighting device 3 . Specifically, the LED lighting device 3 is moved in the vertical direction so as to move the LED lighting device 3 in parallel toward the fixture main body 2 installed on the ceiling, and the LED lighting device 3 is moved into the concave portion 2a of the fixture main body 2. The LED lighting device 3 may be attached to the fixture main body 2 by pressing it in the vertical direction and fitting it.

In the first and second embodiments, an SMD type LED element in which an LED chip is mounted in a package is used as the LED 20, and the light emitting module composed of the substrate 10 and the LED 20 is an SMD type LED module. , but not limited to this. For example, the light-emitting module composed of the substrate 10 and the LEDs 20 may be a COB (Chip On Board) type LED module. In this case, the LED chips (bare chips) themselves are used as the LEDs 20, a plurality of the LEDs 20 (LED chips) are arranged in a straight line on the substrate 10, and the plurality of LEDs 20 are collectively or They may be individually sealed.

Moreover, in Embodiments 1 and 2 above, the cover member 30 having diffusibility and translucency is used, but the present invention is not limited to this. For example, instead of the cover member 30, a translucent cover having only translucency among diffusion and translucency may be used. In this case, a transparent cover having a high transmittance so that the other side can be seen through may be used as the translucent cover.
