Description

  The present invention relates to a reinforcing member that is attached to a reflector for a lighting fixture that expands outward from a mounting position of a light source existing inside.

  Various types of lighting fixtures have been developed, ranging from general lighting used indoors in houses and stores to lighting used outside the room for crime prevention measures, stage lighting, and the like. Lighting equipment used indoors includes lighting equipment installed on a ceiling surface or a wall surface, lighting equipment arranged on a floor or a desk, and the like. For example, as a lighting fixture installed on a ceiling surface, there is a lighting fixture embedded in a ceiling, a so-called downlight. The downlight can be used for both general lighting and partial lighting, and it has the effect of highlighting the interior by adjusting the direction and amount of light irradiation and enhancing the depth of the room, etc. The number of cases adopted in recent years is increasing. A reflector is usually disposed inside a lighting fixture represented by a downlight so as to surround the light source. The reflector plays a role such as distributing light while controlling the intensity of light received from the light source, or diffusing light while adjusting the traveling direction. There are various shapes such as a cylindrical shape, a prismatic shape, etc., and a shape that expands in a downward direction, in the reflector provided in the lighting fixture. Since the direction of illumination and the degree of light distribution can be adjusted depending on the difference in shape, when used, the shape of the reflector is selected in accordance with the purpose of irradiation.

  For example, a reflector used for a downlight installed on a ceiling surface usually has a large opening at the bottom, and the end of this opening is exposed, so it cannot be said that the strength is sufficient. . Therefore, there is a problem that an excessive force is applied at the time of installation on the ceiling surface or damage is easily caused when there is some impact from the outside.

  Conventionally, an end plate main body provided with a reflector made of metal, a metal reflector provided with a claw projecting from the main body of the reflector, and a plate-like end plate that contacts the end of the main body of the reflector And a reinforcing part provided with a reinforcing surface projecting in a direction intersecting with the direction along the surface of the end plate part from the end plate main body part and having a reinforcing surface in a planar contact with the reflector main body. (For example, see Patent Document 1).

  According to Patent Document 1, the reinforcing surface of the reinforcing portion abuts on the reflector main body in a planar shape, and the reinforcing portion has a force in a direction intersecting the direction along the surface of the end plate portion from the end plate main body portion. Even if a force is applied to the end plate, the end plate and the gap between the end plate and the reflection plate are prevented from being damaged, and separate components are used for the end plate and the reflection plate. It is said that it becomes possible to fix firmly without using.

JP 2007-35603 A

  The end plate plays a role of fixing both ends of a straight tube lamp, which is a light source, and a function of reinforcing the reflection plate by supporting both ends of the reflection plate. The reflector of the lighting fixture described in Patent Document 1 seems to be reinforced from the end where the end plate is mounted. However, since the end plate is not mounted in the long side direction of the reflecting plate and the end portion is exposed, it cannot be said that the entire reflecting plate is sufficiently reinforced. Since there is no contrivance from the viewpoint of distributing light while controlling the intensity of light from the light source on the end plate or the reinforcing portion, or diffusing light while adjusting the traveling direction, Patent Document 1 The described lighting fixture cannot be said to be able to effectively transmit light from the light source. In the invention described in Patent Document 1, it is difficult to reinforce the entire reflector while fully utilizing the light from the light source along the irradiation purpose.

  Thus, in the present situation, a reinforcing member that can effectively utilize the light from the light source while reliably reinforcing the reflector for a lighting fixture has not yet been developed.

Hereinafter, the reinforcing member 10 according to the present embodiment will be described with reference to FIGS.

  The lighting fixture that can use the reinforcing member according to the present invention includes a lighting fixture that is installed on a ceiling surface or a wall surface in a room such as a house or a store, a lighting fixture that is placed on a floor or a desk, a spotlight, stage lighting, and an outdoor lamp. And various types. In the present embodiment, an example will be described in which the reinforcing member 10 is used for a lighting fixture that is embedded in a ceiling in a room such as a house or a store, that is, a so-called downlight. However, the reinforcing member 10 of the present invention is not limited to being used for a downlight. There are various types of downlights depending on the depth of embedding in the ceiling surface, such as general type, shallow type, and semi-embedded type, but the reinforcing member 10 according to the present invention can be applied to any shape. It is. It can also be used for direct downlights installed on the ceiling without being embedded in the ceiling. A light source (not shown) such as an incandescent lamp or a fluorescent lamp is disposed inside the downlight, and a reflector 20 is mounted so as to surround the light source.

  The reflector 20 plays a role such as adjusting the intensity of light received from the light source and controlling the traveling direction of the received light, and can adjust the irradiation direction and the degree of light distribution depending on the material and shape thereof. Is possible. When using, the shape of the reflector is selected according to the purpose of irradiation. The reflector includes a cylindrical shape and a shape that expands outward toward the bottom. In the bottom view, there are a circle, an ellipse, a square, an indeterminate shape, and the like, and the reinforcing member according to the present invention can be used in any shape.

  In the present embodiment, the reflector 20 is composed of a plurality of reflectors 1. The reflector 1 is made of a material such as a metal such as aluminum. The reflecting plate 1 has a vertically long trapezoidal shape and is widened downward. Each reflector 1 is formed with four mountain folds in the horizontal direction in the vertical direction. The intervals between the folds are preferably substantially equal. For reference, in FIG. 2, one of the reflectors 1 is surrounded by a thick line.

  The reflector 20 is composed of 16 reflectors 1 having substantially the same shape and size. The 16 reflectors 1 are connected radially with an incandescent lamp as the light source at the center, with the folds on the outside. Examples of the connection method include welding, adhesion, and engagement. Note that “inside” refers to the side that directly receives light from the light source in the reflector 20 and its periphery, and “outside” refers to the side that does not directly receive light from the light source in the reflector 20 and its periphery. Refers to that. As shown in FIG. 2, the donut-shaped fixing portion 30 exists at the center of the reflector 20 in the bottom view. By connecting each reflector 1 and the fixing portion 30 with screws or the like, the 16 reflectors 1 are securely fixed. The light source is fitted into the fixed portion 30. By connecting 16 substantially identical reflectors 1 in this way, the shape in the bottom view is a substantially regular hexagon, and the shape expands outward from the mounting position of the light source existing inside. The reflector 20 is completed. The reflector 20 according to the present embodiment can also be configured by connecting the 80 rectangular reflectors 1 radially around the light source and continuously downward.

  In the present embodiment, four reinforcing members 10 (reinforcing member 10 </ b> A, reinforcing member 10 </ b> B, reinforcing member 10 </ b> C, and reinforcing member 10 </ b> D) are connected to the lower end of reflector 20 in an annular shape, and the lower end of reflector 20 is attached to the lower end of reflector 20. Go all around. The connection method will be described in the description of the protection unit 2 described later. Since the reinforcing member 10 goes around the lower end of the reflector 20, the overall strength of the reflector 20 can be improved. Moreover, since the reinforcing member 10 is configured to be disassembled into a plurality of small parts such as the reinforcing member 10A, the reinforcing member 10B, the reinforcing member 10C, and the reinforcing member 10D, the mounting operation and transportation are simplified. The number of the reinforcing members 10 is not limited to four, and one or a plurality of reinforcing members 10 may be connected to make the lower end of the reflector 20 all around. Further, the reinforcing member 10 may not be attached to the entire circumference of the lower end of the reflector 20. For example, a plurality of reinforcing members 10 can be mounted at a plurality of locations to the extent that a reinforcing effect is exerted on the entire reflector 20.

  The reinforcing member 10 is made of a material that diffuses, refracts, transmits, or reflects light from a light source, specifically, a transparent or translucent resin, and has a light transmittance of 10% to 80% for visible light. Preferably there is. With the reinforcing member 10 having such a configuration, the light received from the light source can be effectively utilized. The reinforcing member 10 exhibits an optical effect and can transmit received light. As a result, while the reflector 20 is reinforced, the reflector 20 and the reinforcing member 10 can cooperate to effectively use the light from the light source. Moreover, such a reinforcing member 10 gives a unique aesthetic effect to the lighting fixture by receiving light.

  In the reinforcing member 10, a protection portion 2 that protects the lower end of the reflector 20 and a contact portion 3 that contacts the reflector 20 from the inside are connected in a substantially L shape in a cross-sectional view including the optical axis of the light source. ing. The optical axis is a virtual line extending vertically downward from the light source. Hereinafter, the protection part 2 and the contact part 3 are demonstrated based on FIG.5 and FIG.6.

  The protection unit 2 has a function of improving the strength of the reflector 20 by reliably protecting the lower end, which is a fragile portion of the reflector 20. The size (width) of the protective part 2 is preferably 1 mm or more and 50 mm or less, more preferably 3 mm or more and 10 mm or less, from the viewpoints of strength, reinforcing effect on the reflector 20, influence on appearance, and the like. . By making the size of the protection part 2 in the width direction larger than the thickness of the reflection plate 1 constituting the reflector 20, the lower end surface of the reflection plate 1 can be sufficiently protected.

  In the present embodiment, since the shape of the reflector 20 in a bottom view is a substantially regular hexagon, when the four reinforcing members 10 (the reinforcing member 10A, the reinforcing member 10B, the reinforcing member 10C, and the reinforcing member 10D) are connected in an annular shape. By the inside of the protection part 2, a substantially regular hexagon is formed in a size capable of protecting the entire periphery of the lower end of the reflector 20 in a bottom view.

  The light from the light source is difficult to reach directly at the outer end of the protection unit 2, but indirectly, that is, light that has hit the reflector 1 at least once or light that has passed through the reinforcing member 10 reaches. In the present embodiment, since the protection unit 2 is chamfered outward, it is possible to increase the range in which light from the light source indirectly strikes and increase the amount of light received from the light source. Since the incident angle of light varies, options for the subsequent light traveling direction increase. As a result, the reflector 20 and the reinforcing member 10 cooperate to use light from the light source more effectively. Further, when the reinforcing member 10 is attached to the reflector 20, the outer end of the protection part 2 is easily noticeable, but the appearance can be improved by chamfering.

  Engaging members for connecting the four reinforcing members 10 to each other are arranged at both ends of the protection part 2. In this embodiment, as shown in FIG. 6, a solid engagement member 10a having a columnar shape, and a hollow engagement member 10b having a cylindrical shape of a size that allows the engagement member 10a to be inserted into and closely contacted with the inside. And are used. One of the engaging member 10 a and the engaging member 10 b is disposed at both ends of the protection unit 2. Of the both ends of the protection part 2, the cylindrical part which comprises cylindrical shape penetrates the protection part 2, and forms the hole shape in the edge part by the side which has the engaging member 10b. When connecting two reinforcing members, for example, the reinforcing member 10A and the reinforcing member 10B, the engaging member 10a is inserted into the engaging member 10b. By setting it as such a structure, it becomes possible to connect several parts reliably and it becomes possible to improve the intensity | strength of the reflector 20 more.

  The contact part 3 contacts the inner side of the reflecting plate 1 in a planar shape. In the present embodiment, the substantially entire surface of the contact portion 3 is in contact with the reflector 20. As a result, while the reflector 20 is reliably reinforced, the reflector 20 and the reinforcing member 10 cooperate to use light from the light source more effectively. The size in the height direction of the contact part 3 is preferably 1 mm or more and 50 mm or less, more preferably 3 mm or more and 10 mm or less from the viewpoints of strength, a reinforcing effect on the reflector 20, an influence on the appearance, and the like. is there. From the same viewpoint, the size of the contact portion 3 in the width direction is preferably 3 mm or more and 30 mm or less, and more preferably 8 mm or more and 20 mm or less.

  In the present embodiment, since the shape of the reflector 20 in a bottom view is a substantially regular hexagon, when the four reinforcing members 10 (the reinforcing member 10A, the reinforcing member 10B, the reinforcing member 10C, and the reinforcing member 10D) are connected in an annular shape. The inside of the contact portion 3 forms a substantially regular hexagon having a size that can be engaged with the entire periphery of the lower end of the reflector 20 in a planar view when viewed from the bottom.

  In order to engage the reinforcing member 10 and the reflector 20, the contact portion 3 has a convex portion 4 that is a protruding portion, and each of the 16 reflectors 1 engages with the convex portion 4 around the lower end portion. It has the recessed part 5 of the shape to do. Specifically, the convex portion 4 has a cylindrical shape, and the concave portion has a hole shape. By fitting the convex portion 4 and the concave portion 5, the reflector 20 and the reinforcing member 10 are firmly fixed. Thus, in this embodiment, since the reinforcing member 10 is engaged with each of the 16 reflectors 1 at the lower end of the reflector 20, loosening that occurs between the reflectors 1 can be reduced and strengthened. Can connect. As a result, the reflector 20 can be more reliably reinforced.

  Since the contact portion 3 is thicker in the downward direction, the strength of the contact portion 3 itself is improved and it is easy to withstand external impacts. As a result, the strength of the entire reinforcing member 10 is improved, and the reinforcing effect on the reflector 20 is further improved. Furthermore, when the reinforcing member 10 is attached to the reflector 20, the reinforcing member 10 is inclined inward, so that the amount of light received directly or indirectly from the light source increases. As a result, the reflector 20 and the reinforcing member 10 cooperate to use light from the light source more effectively.

  The contact part 3 is provided in the position where the light from a light source reaches directly. That is, there is no tangible object that blocks the progress of light, for example, a part of the reflector 20 between the light source and the contact portion 3, and the light from the light source directly strikes the contact portion 3. The light from the light source can be used efficiently, and the traveling direction of the light after hitting the contact portion 3 can be easily predicted. As a result, the reflector 20 and the reinforcing member 10 cooperate to use light from the light source more effectively.

  In the present embodiment, since the connecting portion 6 in which the protection portion 2 and the contact portion 3 are connected in a substantially L shape in a cross-sectional view including the optical axis of the light source is rounded inward, The range over which light is directly or indirectly applied can be increased. As a result, the amount of light received by the reinforcing member 10 from the light source increases, and the reflector 20 and the reinforcing member 10 cooperate to make more effective use of light from the light source.

  The reinforcing member of the reflector for a lighting device of the present invention includes, for example, a downlight used in a room such as a house or a store, a lighting device installed on a ceiling surface or a wall surface, a lighting device placed on a floor or a desk, It can be used for lighting fixtures such as spotlights and outdoor lights.
