[ embodiment 1]
[ LED Lighting apparatus ]
Fig. 1 is a perspective view of an example of an LED lighting fixture according to the present embodiment as viewed from below. The LED lighting fixture 1000 includes, as main components, an LED light source unit 100 having a friction reducing portion and a main body unit 200. Hereinafter, the structure of the LED light source unit 100 will be described first, and then the structure of the main body unit 200 will be described. The LED light source unit and the main body unit described below are also descriptions of the LED light source unit and the main body unit of the present invention, respectively.
[ LED light source Unit ]
Fig. 2(a) and 2(b) are a perspective view from below and a perspective view from above, respectively, showing an example of the LED light source unit of the present embodiment. The LED light source unit 100 is the same as the LED light source unit 100 of fig. 1. The LED light source unit 100 includes the LED-mounted substrate 10, the mounting member 20, and the cover member 30 as main components, and includes the power supply unit 40 as an arbitrary component.
(1) LED assembly substrate
As shown in fig. 2(a) and 2(b), the LED-mounted substrate 10 is a substrate having an LED11 mounted on one surface (mounting surface) 12. In the LED-mounted substrate 10 shown in fig. 2(a) and 2(b), a plurality of LEDs 11 are mounted on the mounting surface 12 of the substrate, but in the present embodiment, the number of LEDs 11 is not limited to this, and may be one. The LED-mounted substrate 10 is connected to the power supply unit 40 by a power supply connection member such as a wire. In the present embodiment, a connector for electrically connecting the LED-mounted substrate 10 and the power supply unit 40, for example, may be attached to the rear end of the LED-mounted substrate 10, and the connector may be connected to the power supply unit 40 by the power supply connecting member.
In the present embodiment, the number of substrates (unit substrates) constituting the LED-mounted substrate 10 may be one or more. In the case where the unit substrates are plural, the LED-mounted substrate 10 may be configured by connecting the unit substrates to each other via a connecting member such as a connector in the longitudinal direction Y of the LED-mounted substrate 10, for example.
(2) Mounting component
The mounting member 20 shown in fig. 2(a) and 2(b) is a mounting member for a main unit having a recess capable of accommodating the mounting member 20. The mounting component 20 shown in fig. 2(a) and 2(b) is disposed on the surface of the LED-mounted substrate 10 opposite to the mounting surface 12.
The structure of the mounting member 20 shown in fig. 2(a) and 2(b) will be described with reference to fig. 3. Fig. 3 is a perspective view showing an example of the mounting member 20. The mounting member 20 shown in fig. 3 is composed of a pair of bottom portions 21, a pair of side wall portions 22, and a base portion 23. The bottom portions 21 of the pair of bottom portions and the base portion 23 are connected by the pair of side wall portions 22. Each bottom portion 21 is provided with a screw fastening hole 24 for fixing to the LED mounting substrate 10. Thereby, the LED-mounted substrate 10 is mounted on the mounting component 20 using a fixing member such as a screw. Each side wall portion 22 is provided with one locking hole 25, and the base portion 23 is provided with two locking holes 26. These locking holes 25 and 26 are locking holes for leaf spring-shaped locking pieces provided on the main unit side described later. As shown in the LED lighting fixture 1000 of fig. 1, the LED light source unit 100 is attached to the main body unit 200 by engaging the leaf spring-like engaging pieces in the engaging holes 25 and 26. In this case, as shown in fig. 1, the mounting member 20 is housed in a recess of the main unit 200 when in use.
(3) Cover component
The cover member 30 shown in fig. 2(a) and 2(b) is a cover member for the LED-mounted board 10. In use, the cover member 30 is disposed so as to cover the mounting surface of the LED-mounted board 10 and the opening of the recess 211 of the main unit 200 in the vertical direction Z perpendicular to the mounting surface 12 of the LED-mounted board 10.
The cover member 30 includes, for example, a cover portion 31 that covers the mounting surface 12 of the LED mounting substrate 10 and a rail portion 32 that houses the LED mounting substrate 10. In the present embodiment, the rail portion 32 is an arbitrary component, and the rail portion 32 may not be provided.
The cover portion 31 has a pair of extension regions 33 formed by extending a pair of edge portions H in the short direction X of the cover member 30 outward in the short direction X from an opening of a concave portion 211 of the main unit 200 shown in fig. 4 described later. In use, the pair of opening edge portions L in the short-side direction X of the concave portion 211 of the main unit 200 and the pair of extension regions 33 of the cover member 30 opposed to the pair of opening edge portions L are respectively overlapped in the long-side direction Y in the vertical direction Z perpendicular to the mounting surface 12 of the LED-mounted board 10, and the pair of opening edge portions L and the pair of extension regions 33 of the cover member 30 opposed thereto are directly or indirectly brought into contact. Here, the direct contact means, for example, a mode in which the pair of opening edge portions L and the pair of opposing extension regions 33 are directly contacted, and the indirect contact means a mode in which the pair of opening edge portions L and the pair of opposing extension regions 33 are contacted via another member such as a spacer described later. The direct or indirect contact means, for example, that no gap is formed between the pair of opening edge portions L and the pair of extending regions 33 of the cover member 30 facing thereto.
The pair of extension regions 33 shown in fig. 1 have friction reducing portions 35 at portions opposing the pair of opening edge portions L of the main unit 200. In use, the friction reducing portion 35 reduces friction generated between the pair of extension regions 33 of the cover member 30 and the pair of opening end edges L of the main unit 200.
The friction reducing portion 35 may have a spacer, for example. In this case, the pair of opening edge portions L and the pair of extension regions 33 indirectly contact via the spacer.
The spacer is not particularly limited, and examples thereof include a tape such as an adhesive tape, a rubber elastic body (elastic body) sheet, and the like. The belt is not particularly limited, and examples thereof include a glass belt, a metal belt, a resin belt, and a rubber belt. Examples of the glass ribbon include a ribbon woven from glass fibers. Examples of the metal strip include an aluminum strip formed by thinning an aluminum material. Examples of the resin tape include a resin tape made of a fluororesin or the like. Examples of the elastomer tape include a resin tape such as thermoplastic polyurethane. The thickness of the film of the tape is not particularly limited, and is, for example, 0.005 to 1.0 mm. In the case where the spacer is a tape, the tape is attached to the opposite portions of the pair of extension regions 33, for example.
The friction reducing portion 35 may have a lubricant layer, for example. In this state, the pair of opening edge portions L and the pair of extension regions 33 indirectly contact via the lubricant layer.
The lubricant is not particularly limited, and examples thereof include lubricating oil, grease, and fluororesin paint.
The lubricant layer is formed by, for example, disposing the lubricant on the opposing portions of the pair of extended regions 33. The method of disposing the lubricant is not particularly limited, and may be performed according to a general known technique, for example, although coating or the like is exemplified.
The friction reducing portion 35 may have, for example, a rough surface layer having a concave-convex surface. Via the rough surface layer, for example, the pair of opening edge portions L and the pair of extension regions 33 are directly or indirectly in contact.
The rough surface layer is, for example, a surface layer of the pair of extended regions 33, and the surface layer is formed by roughening the surface. Alternatively, the rough surface layer is, for example, a surface layer of the pair of extended regions 33, and the pair of extended regions 33 are resin bodies containing a filler. In this case, the pair of opening edge portions L and the pair of extension regions 33 are, for example, in direct contact.
The roughening treatment is not particularly limited, and examples thereof include surface polishing, blasting such as shot blasting or sand blasting, and embossing. The surface treatment is preferably the blasting treatment. The roughening treatment may be performed according to a generally known technique.
The filler contained in the resin body is not particularly limited, and may be, for example, a filler capable of forming irregularities on the surface of the resin body. The resin body has a surface with an uneven shape, for example, by aggregating the filler on the surface. Examples of the filler include inorganic particles such as silica particles, titanium oxide particles, and alumina particles, and organic particles such as polymethyl methacrylate resin powder (PMMA particles), silicone resin powder, and polystyrene resin powder. These inorganic particles and organic particles may be used singly or in combination. The method for agglomerating the filler on the surface is not particularly limited as long as it is carried out according to a generally known technique.
Each of the pair of rail portions 32 is arranged in a state of standing with respect to the pair of extension regions 33. Each rail portion 32 has a groove 34 therein in the longitudinal direction Y. The LED-mounted substrate 10 is slidably inserted into the groove 34 of each rail portion 32, for example. In use, as shown in fig. 1, the pair of rail portions 32 are housed in the concave portion 211 of the main unit 200.
The cover member 30 may be configured to transmit the irradiation light from the LED11, or may be configured to diffuse the irradiation light. The material for forming the cover member 30 is not particularly limited, and examples thereof include a transparent polycarbonate, an acrylic resin, and the like.
The shape of the cover portion 31 of the cover member 30 is a substantially inverted trapezoidal shape, but in the present embodiment, the shape of the cover portion is not limited to this as long as it has a pair of extension regions 33. The shape of the cover portion may be, for example, a substantially convex lens shape, a substantially semicircular shape, a substantially fan-shaped shape, a substantially trapezoidal shape, or the like, and may have the above-described shapes as exemplified above.
In the present embodiment, as described above, the pair of rail portions 32 are arbitrary components as components of the cover member 30, and the pair of rail portions 32 may be omitted. When the cover member 30 does not include the pair of rail portions 32, the LED-mounted board 10 may be disposed on the upper surface of the cover portion 31 and fixed using a fixing member such as a screw, for example.
(4) Power supply unit
As shown in fig. 2(a) and 2(b), the power supply unit 40 is disposed, for example, at a substantially central portion of the surface of the LED-mounted substrate 10 opposite to the mounting surface 12.
The power supply unit 40 includes, for example, a power supply board and a case, and the power supply board is housed in the case. The power supply board is, for example, a board on which circuit components for driving the LED11 are mounted, and the LED11 is driven by electrically connecting the power supply unit 40 to the LED-mounted board 10.
(5) Side cover
In the present embodiment, the LED light source unit 100 has side covers for closing openings at both ends of the cover member 30 in the longitudinal direction. The side cover is attached to the cover portion 31 so as to be fitted thereto, for example.
[ Main body Unit ]
Next, a main body unit 200, which is a component of the LED lighting fixture 1000 of the present embodiment, will be described with reference to fig. 4. The body unit 200 is the same as the body unit 200 of fig. 1.
The main body unit 200 includes, for example, a main body plate 210 and a pair of plate spring-like locking pieces 220.
The main body plate 210 has, for example, a recess 200 extending in the longitudinal direction Y and an inclined surface extending in the longitudinal direction Y and connected to the recess 200. The cross-sectional shape of the recess 200 in the width direction is concave, and the cross-sectional shape of the inclined surface in the width direction is tapered so as to expand upward.
The plate spring-like locking pieces 220 are attached to the front end side and the rear end side in the longitudinal direction Y of the main body plate 210. The plate spring-like locking piece 220 is formed, for example, in a shape folded back toward the middle of the front end 222, and has the folded-back end 221. Folded end 221 has a curved shape. As shown in fig. 1, the main unit 200 can be mounted to the mounting member 20 by engaging the leaf spring-like engaging piece 220 with the mounting member 20 by passing the folded end portion 221 through the engaging hole 26 of the base portion 23 of the mounting member 20 and passing the tip end portion 222 through the engaging hole 25 of each side wall portion 22.
The main body plate 210 and the plate spring-like locking piece 220 are formed by, for example, bending a metal plate and removing unnecessary portions.
In the body unit 200, for example, a hole (not shown) is provided in the bottom surface 213 of the recess 211 of the body plate 210, a hanger bolt provided in a ceiling member is inserted through the hole, and a fixing member such as a nut is screwed into the hanger bolt to fix the body unit 200 to the ceiling member.
The main body unit 200 may further include a terminal base as a component. The terminal base is disposed on, for example, a bottom surface 213 of the concave portion 211 of the main body plate 210. In order to supply electric power to the power supply unit 40, a power supply line exposed to the ceiling member side may be connected to the terminal base, and an electric wire electrically connected to the power supply unit 40 may be further connected thereto.
A method of attaching the LED light source unit 100 shown in fig. 2(a) and 2(b) to the main body unit 200 shown in fig. 4 and installing the LED lighting fixture 1000 of fig. 1 will be described below. As described above, the folded end portions 221 of the leaf spring-shaped locking pieces 220 provided at the front end portion and the rear end portion of the main unit 200 are inserted through the locking holes 26 of the base portion 23 of the mounting member 20, and the front end portions 222 are inserted through the locking holes 25 of the side walls 22 of the mounting member 20. Thus, the attachment member 20 is attached to the main unit 200 in a state of being accommodated in the opening 211 of the main unit 200. At this time, the pair of opening edge portions L in the short-side direction X of the concave portion 211 of the main unit 200 and the pair of extension regions 33 of the cover member 30 facing the pair of opening edge portions L overlap each other in the long-side direction Y in the vertical direction Z perpendicular to the mounting surface 12 of the LED-mounted substrate 10. The pair of opening edge portions L directly or indirectly contact the pair of extending regions 33 of the cover member 30 opposed thereto. In this way, the LED lighting fixture 1000 shown in fig. 1 can be provided by attaching the LED light source unit 100 to the main body unit 200.
In the present embodiment, for example, the plate spring-like locking piece 220 may be manually bent to be appropriately adjusted so that the pair of opening edge portions L of the concave portion 211 of the main unit 200 and the pair of extending regions 33 of the cover member 30 facing thereto are brought into direct or indirect contact with each other.
An example of a method of mounting the main body unit 200 of the LED lighting fixture 1000 of fig. 1 to a ceiling member will be described below. A hanger bolt provided in a ceiling member is inserted through a hole (not shown) provided in the bottom surface 213 of the recess 211 of the main body plate 210 of the main body unit 200, and a fixing member such as a nut is screwed into the hanger bolt to be fixed to the ceiling member. In this way, the LED lighting fixture 1000 of fig. 1 can be mounted on a ceiling member.
In the LED lighting fixture 1000 shown in fig. 1, as described above, the pair of opening edge portions L and the pair of extension regions 33 of the cover member 30 opposed thereto are respectively overlapped in the longitudinal direction Y in the vertical direction Z perpendicular to the mounting surface 12 of the LED mounting substrate 10. The pair of opening edge portions L directly or indirectly contact the pair of extending regions 33 of the cover member 30 opposed thereto. Thus, the LED lighting fixture 1000 shown in fig. 1 does not become dark in a stripe shape when lit, and the appearance when lit is improved.
In a typical LED lighting device, a resin is used as a material for forming the cover member, and a metal is used as a material for forming the device main body. That is, the cover member and the device body are formed of materials having different expansion rates. Therefore, as in the LED lighting fixture described in patent document 1, when the extending portions overlap the opening edge in the orthogonal direction without a gap, a noise due to friction is generated on the contact surface between the fixture main body and the cover member due to a temperature change during lighting or lighting-off.
In contrast, in the LED lighting fixture 1000 shown in fig. 1, the friction reducing portion 35 is provided at the opposing portions of the pair of extension regions 33 of the cover member 30. In the LED lighting fixture 1000, the friction reducing portion 35 reduces friction generated between the pair of extension regions 33 of the cover member 30 and the pair of opening edge portions L of the main unit 200. Thus, the LED lighting fixture 1000 shown in fig. 1 can suppress noise generated when the cover member 30 and the edge of the opening of the main unit 200 rub against each other due to a temperature change during lighting or during lighting-off. Therefore, the LED lighting fixture of the present invention can suppress sound without being affected by the difference in material as described above, for example.
[ embodiment 2]
Fig. 5 is a perspective view of an example of the LED lighting fixture according to the present embodiment as viewed from below. The LED lighting fixture 2000 includes, as main components, an LED light source unit 300 and a main body unit 400 having a friction reducing portion. The LED lighting fixture 2000 is similar to the LED lighting fixture 1000 according to embodiment 1 shown in fig. 1, except that the friction reducing portions 435 are provided at the portions of the opening edge portion L of the recess 211 of the fixture main body 400 that face the pair of extension regions 33, instead of the facing portions of the pair of extension regions 33 of the cover member 30.
In the present embodiment, first, the pair of opening edge portions L of the device main body 400 and the pair of extending regions 33 of the cover member 30 opposed thereto are also in direct or indirect contact. Further, the friction reducing portions 435 reduce friction generated between the pair of extension regions 33 of the cover member 30 and the pair of opening edge portions L of the main unit 400. Therefore, as in embodiment 1, the LED lighting fixture 2000 of the present embodiment does not darken in a stripe shape due to the occurrence of the gap when lighting, and can suppress the sound generated when lighting or turning off the LED light source unit 100 while providing a good appearance.
The friction reducing portion 435 may be provided with a spacer, for example. In this case, the pair of opening edge portions L and the pair of extension regions 33 indirectly contact via the spacer.
