A power supply line exposed on the ceiling material side is connected to the terminal block to supply electric power to the power supply unit 40, and an electric wire for electrically connecting to the power supply unit 40 is further connected. May be good.

Hereinafter, a method of attaching the LED light source unit 100 shown in FIG. 2 to the main body unit 200 shown in FIG. 4 and setting the LED lighting fixture 1000 of FIG. 1 will be described. As described above, the folded end 221 of each leaf spring-shaped locking piece 220 provided at the front end and the rear end of the main body unit 200 is passed through the locking hole 26 of the base portion 23 of the mounting member 20. The tip portion 222 is passed through the locking holes 25 of each side wall 22 of the mounting member 20. As a result, the mounting member 20 is mounted on the main body unit 200 in a state of being housed in the recess 211 of the main body unit 200. At this time, the pair of opening edge portions L in the lateral direction X of the concave portion 211 of the main body unit 200 and the convex portion 35 of the pair of extending regions 33 of the cover member 30 facing the pair of opening edge portions L are LEDs. It overlaps along the longitudinal direction Y in the direction Z perpendicular to the mounting surface 12 of the mounting board 10. As a result, as shown in FIG. 1, a plurality of gaps 50 are provided between the pair of opening edge portions L and the region of the cover member 30 facing the pair of opening edge portions L that does not have the convex portion 35. In this way, the LED light source unit 100 can be attached to the main body unit 200, and the LED lighting fixture 1000 shown in FIG. 1 can be set.

In the present embodiment, for example, a leaf spring-like engagement is made so that the convex portion 35 of the pair of extending regions 33 of the cover member 30 and the pair of opening edge portions L in the lateral direction X of the concave portion 211 overlap each other. It may be adjusted appropriately by bending the stop piece 220 manually.

Hereinafter, an example of a method of attaching the main body unit 200 of the LED lighting fixture 1000 of FIG. 1 to the ceiling material will be described. A hanging bolt provided on the ceiling material is passed through a hole (not shown) on the bottom surface 213 of the recess 211 of the main body plate 210 provided in the main body unit 200, and a fixing means such as a nut is screwed into the hanging bolt. Fix it to the ceiling material. In this way, the LED lighting fixture 1000 of FIG. 1 can be attached to the ceiling material.

In a general LED lighting fixture, resin is used as a forming material for a cover member, and metal is used as a forming material for the fixture body. That is, the cover member and the instrument body are made of materials having different expansion coefficients. Therefore, as in the LED lighting fixture described in Patent Document 1, when each of the extending portions overlaps the opening edge without a gap in the orthogonal direction, the fixture main body due to a temperature change when the lighting or extinguishing is performed. In addition, noise is generated due to friction on the contact surface of the cover member.

On the other hand, in the LED luminaire 1000 shown in FIG. 1, as described above, the pair of opening edges L and the convex portion 35 of the extending region 33 of the cover member 30 facing the pair of opening edges L overlap with each other. A plurality of gaps 50 are provided between the portion L and the extension region 33 having no convex portion 35. Since the LED lighting fixture 1000 has a gap 50, it is possible to suppress the noise generated by the rubbing of the cover member 30 and the main body unit 200 caused by the temperature change when the LED lighting fixture 1000 is turned on or off. Therefore, the LED lighting fixture of the present invention can suppress sound noise without being affected by the difference in materials as described above, for example.

Further, since the LED lighting fixture 1000 has a gap 50, an air flow is generated between the inside of the recess 211 opening of the main body plate 210 and the outside, and the heat generation of the LED 11 and the power supply unit 40 at the time of lighting can be alleviated. .. Therefore, it is possible to improve the decrease in the luminous efficiency of the LED 11 at a high temperature. Further, it is possible to improve the problem that the LED 11 or the power supply unit 40 breaks down at a high temperature.

The tape is not particularly limited, and examples thereof include glass tape, metal tape, resin tape, and elastomer tape. Examples of the glass tape include tapes woven with glass fibers. Examples of the metal tape include aluminum tape made by thinning aluminum. Examples of the resin tape include tapes made of resin such as fluororesin. Examples of the elastomer tape include tapes such as thermoplastic polyurethane.

The height (also referred to as thickness) of the spacer 60 is not particularly limited, and is, for example, 0.005 to 1 mm. The width of the spacer 60 is not particularly limited, and is, for example, 1 to 100 mm. In the present embodiment, for example, the height and width of the gap 50 are set by setting the height and width of the spacer -60.

As shown in FIG. 5, since the pair of opening edges L and the spacers 60 arranged in the pair of extending regions 33 of the cover member 30 facing the pair overlap, the pair of opening edges L and the spacers 60 overlap. It has a plurality of gaps 50 with and from a pair of unarranged extension areas 33. Since the LED lighting fixture 2000 has a gap 50, it is possible to suppress the noise generated by the rubbing of the cover member 30 and the main body unit 200 caused by the temperature change when the LED lighting fixture 2000 is turned on or off. Further, since the gap 50 is provided, an air flow is generated between the inside of the recess 211 opening of the main body plate 210 and the outside, and the heat generation of the LED 11 and the power supply unit 40 at the time of lighting can be alleviated. Therefore, it is possible to improve the decrease in the luminous efficiency of the LED 11 at a high temperature. Further, it is possible to improve the problem that the LED 11 or the power supply unit 40 breaks down at a high temperature.

The LED luminaire 2000 has a plurality of gaps 50 between the pair of opening edges L and the extension area 33 of the portion of the cover member 30 facing the LED luminaire 2000 in which the spacer 60 is not arranged. The number of gaps 50 is not limited to this, and may be one.

The LED light source unit 400 has a pair of side caps 70 in order to form a gap between the pair of opening edge portions L of the main body unit 200 and the extending region 33 of the cover member 30 facing the opening edge L. A part of the side cap 70 is in contact with a pair of opening edges L of the main body unit 200. The LED light source unit 400 is the same as the LED light source unit 100 of FIG. 1 except that the cover member 30 does not have a convex portion 35 and further has a pair of side caps 70. Further, the main body unit 200 is the same as the main body unit 200 of FIG. The LED luminaire 3000 is the same as the LED luminaire 1000 of FIG. 1 except for these. The LED light source unit described below is also a description of the LED light source unit of the present invention.

Each of the pair of side caps 70 is a side cap for the cover member 30, and may be, for example, not only the cover member 30, but also a side cap for the cover member 30 and the substrate of the LED mounting substrate 10. Hereinafter, the form of the side cap with respect to both the cover member 30 and the substrate of the LED mounting substrate 10 will be shown, but the present invention is not limited to this, and for example, the form of the side cap with respect to the cover member may be used. As shown in FIG. 6, each of the pair of side caps 70 has an insertion portion (not shown) into which the end portion of the cover member 30 (and optionally the substrate 10) in the longitudinal direction Y is inserted, and the LED mounting substrate. In the direction Z perpendicular to the mounting surface of 10, at least one gap forming portion is provided in the upward direction of the insertion portion toward the opening edge portion L of the main body unit 200. Specifically, the side cap 70 of FIG. 6 is provided with a convex portion 71 as a gap forming portion above the insertion portion in the lateral direction X. In FIG. 7A, the height of the end portion of the cover member 30 inserted into the side cap 70 in the lateral direction X is represented by H. In FIG. 6, the end portion of the side cap 30 in the lateral direction X, the height on the outer side is represented by K, and the height on the inner side is represented by M. Then, in the side cap 70, the height M on the inner side substantially corresponds to the height H of the end portion of the cover member 30, and the insertion portion is provided at substantially the same position. Further, in the side cap 70, a region protruding from the height M on the inner side is the gap forming portion 71.

As shown in FIG. 7A, both ends of the cover member 30 (and optionally the substrate 10) in the longitudinal direction are inserted into the pair of side caps 70 during use. As a result, both ends of the light source unit 400 are closed, and the space between the cover member 30 and the substrate 10 can be hidden (capped) from the outside by the side cap 70. Further, as shown in FIG. 7B, the LED light source unit 400 to which the side cap 70 is attached is attached to the main body unit 200. At this time, the upward end of the convex portion 71 of the side cap 70 comes into contact with the opening edge portion L of the main body unit 200. Specifically, the side cap 70 contacts the end of the recess of the main body unit 200 in the longitudinal direction Y (including the pair of ends in the lateral direction X) in the vertical direction Z, but the gap between the side caps 70. Since the forming portion 71 is formed upward from the insertion portion of the cover member 30 (and optionally the substrate 10), the opening edge portion L and the cover member 30 facing the opening edge portion L are formed in the longitudinal direction Y of the cover member 30. A gap substantially corresponding to the height (height K-height M or height K-height H) of the gap forming portion 71 of the side cap is formed between the extension region 33 and the side cap. ..

Since the LED lighting fixture 3000 shown in FIG. 7B has a gap 50, it is possible to suppress the noise generated by the rubbing of the cover member 30 and the main body unit 200 caused by the temperature change at the time of lighting or extinguishing. Further, since the gap 50 is provided, an air flow is generated between the inside of the recess 211 opening of the main body plate 210 and the outside, and the heat generation of the LED 11 and the power supply unit 40 at the time of lighting can be alleviated. Therefore, it is possible to improve the decrease in the luminous efficiency of the LED 11 at a high temperature. Further, it is possible to improve the problem that the LED 11 or the power supply unit 40 breaks down at a high temperature.

The shape of the side cap 70 is not limited to the shape shown in FIG. 6, and in addition, a gap can be formed between the pair of opening edge portions L and the extension region 33 of the cover member 30 facing the pair of opening edge portions L. Things can be used. Other examples of side caps are shown in FIGS. 8 (a) and 8 (b). Unless otherwise specified, each side cap is the same as the description of FIGS. 6 and 7.

FIG. 8A is a perspective view showing another example of the side cap, the left figure is a perspective view of the side cap 80, and the right figure is an upward direction of the LED light source unit 400 to which the side cap 80 is attached.

Each of the pair of side caps 80 has an insertion portion into which the longitudinal end of the cover member 30 (and optionally the substrate 10) is inserted, as shown in the left view of FIG. 8A (not shown). ), The gap forming portion 81 is provided in the direction Z perpendicular to the mounting surface of the LED mounting substrate 10 in the upward direction of the insertion portion toward the opening edge portion L of the main body unit 200. The gap forming portion 81 in the side side cap 80 will be described with reference to the right figure of FIG. 8A. In FIG. 8A, the height of the end portion of the side cap 80 in the lateral direction X is represented by K, and the height of the end portion of the cover member 30 inserted into the side cap 80 in the lateral direction X is , Represented by H. Since the end portion of the cover member 30 in the longitudinal direction Y is inserted into the side cap 80, the side cap 80 has the insertion portion of the cover member 30 at a position corresponding to the height H of the cover member 30. Therefore, in the side cap 80, the region above the height H becomes the gap forming portion 81.

The LED light source unit 400 to which the side cap 80 is attached is attached to the main body unit 200. At this time, the upper end of the side cap 80 comes into contact with the opening edge L of the main body unit 200. Specifically, the side cap 80 contacts the end of the recess of the main body unit 200 in the longitudinal direction Y (including a pair of ends in the lateral direction) in the vertical direction Z, but forms a gap in the side cap 80. Since the portion 81 is formed upward from the insertion portion of the cover member 30 (and optionally the substrate 10), the opening edge portion L and the cover member 30 facing the opening edge portion L in the longitudinal direction Y of the cover member 30 A gap substantially corresponding to the height (height K-height H) of the gap forming portion 81 of the side cap is formed between the extension region 33 and the side cap.

For example, the side cap 80 of FIG. 8A may have a pair of gap forming portions at the end portion in the lateral direction X instead of having the gap forming portion 81 over the end portion in the longitudinal direction Y. .. This form is shown in FIG. 8 (b). FIG. 8B is a perspective view showing another example of the side cap, the left figure is a perspective view of the side cap 90, and the right figure is an upward direction of the LED light source unit 400 to which the side cap 90 is attached. The perspective view from is shown. Each of the pair of side caps 90 has an insertion portion for inserting the end portion of the cover member 30 (and optionally the substrate 10) in the longitudinal direction Y, as shown in the left view of FIG. 8 (b) (shown). In the direction Z perpendicular to the mounting surface of the LED mounting substrate 10, two convex portions are provided as a pair of gap forming portions 91 in the upward direction of the insertion portion toward the opening edge portion L of the main body unit 200. ..

The LED light source unit 400 to which the side cap 90 is attached is attached to the main body unit 200. At this time, the upper end of the side cap 90 comes into contact with the opening edge L of the main body unit 200. Specifically, the side cap 90 comes into contact with the longitudinal end of the recess of the main body unit 200 (including the pair of ends in the lateral direction X) in the vertical direction Z, but forms a gap in the side cap 80. Since the portion 91 is formed upward from the insertion portion of the cover member 30 (and optionally the substrate 10), the opening edge portion L and the cover member 30 facing the opening edge portion L in the longitudinal direction Y of the cover member 30 A gap is formed between the extension region 33 and the side cap so as to substantially correspond to the height of the gap forming portion 91 of the side cap.

In the present embodiment, the side cap may further have, for example, a convex portion for inserting the main body unit into the concave portion. When the cover member on which the side cap is arranged is arranged on the main body unit, the insertion convex portion is formed in the gap between the inner wall of the concave portion of the main body unit and the cover member. The side cap is provided so that it can be inserted in contact with the side cap. An example of this side cap is shown in FIG. The side cap 90 in FIG. 9 is a form in which the side cap 90 in FIG. 8B further has a pair of insertion protrusions 92.

The cross-sectional view of X is shown. FIG. 9 is the same as FIG. 8 (b) except that the side cap 90 has a convex portion 92 for insertion.

When the cover member 30 on which the side cap 90 is arranged is arranged on the main body unit 200, the insertion convex portion 92 is formed in the gap between the inner wall of the concave portion of the main body unit 200 and the rail portion 32 of the cover member 30. The side cap 90 is provided so that it can be inserted in contact with both.

The side cap 90 of FIG. 9 is formed by inserting the substrate 10 and the cover member 30 to form an LED light source unit, and when the side cap 90 is attached to the main body unit 200, the insertion convex portion 91 is the concave portion of the main body unit 200. It is inserted into the gap between the inner wall and the cover member 30 in contact with both of them. As a result, as shown in the lower figure of FIG. 9, after the LED light source unit 400 is attached to the main body unit 200, rattling of the LED light source unit 400 in the lateral direction X can be suppressed. Therefore, for example, it is possible to avoid contact between the side surface of the rail portion 32 of the resin cover and the recessed side surface of the main body unit 200 due to the movement of the LED light source unit 400 in the lateral direction X, and the noise and heat generation due to the contact can be avoided. Further effects on the above can be avoided.

The height of the insertion convex portion 91 in the vertical direction Z is not particularly limited, and is, for example, 0.5 to 5 mm.

In FIG. 9, the form in which the side cap of FIG. 8B is provided with the insertion convex portion 92 is illustrated, but the insertion convex portion can be applied regardless of the type of the side cap, for example, FIG. It can also be applied to the side cap of 6 and FIG. 8 (a).
