Description

  The present invention relates to a luminaire, and more particularly, to a luminaire using an electrical light source and including a cover that covers the light source from the side of an illuminated surface.

  One of these types of lighting fixtures has a structure in which a straight tube fluorescent lamp is used as a light source and is directly fixed to a horizontal top surface or a vertical surface such as an indoor wall, ceiling, side of a fixture, or under a shelf. .

  FIG. 7 shows an exploded perspective view and a perspective side view of an example of a conventional lighting fixture. FIG. 7 (a) is an exploded view of a state in which the luminaire is attached to a vertical wall surface such that the longitudinal direction (the direction along the tube axis of the straight tube fluorescent lamp 10 of the light source) is parallel to the floor surface. It shows a place looked up diagonally from the lower left. FIG.7 (b) has shown the place which looked at the lighting fixture from the longitudinal direction.

  Referring to FIG. 7, the lighting fixture shown in this figure includes a fixture main body 1, a socket 11, a socket fitting 2, a side plate 12, and a cover 3. In addition, various components necessary for the lighting power supply and lighting / extinguishing control, such as a lighting circuit 13 and a switch 14 that is turned on / off by a drawstring, are provided.

  The fixture body 1 is a base of the lighting fixture, and is formed by bending a metal plate having a length corresponding to the fluorescent lamp 10 so that the cross section becomes a “U” -shaped groove. Various components such as the above-described socket fitting 2, lighting circuit 13, or switch 14 are attached to the instrument body 1. The instrument body 1 has a through hole (not shown) formed in a portion (that is, the bottom of the groove) that hits the vertical bar of the “U” shape, and is screwed to the wall surface with a wood screw (not shown) through the hole. The instrument body 1 is mostly made of metal. This is because sufficient mechanical strength required for the base can be secured and processing is easy.

  The socket fitting 2 is mostly made of metal, and is made by bending a metal plate with a press. The lighting fixture is fixed to the fixture main body 1 by screws or the like, one by one on the left and right along the longitudinal direction of the lighting fixture, with a distance corresponding to the length of the fluorescent lamp 10.

  One socket 11 is fixed to each of the two socket fittings 2 described above. In the straight tube fluorescent lamp 10, terminals 15 provided at both ends of the lamp are fitted into the socket 11, and are fixed to the socket so as to be detachable. The socket 11 also serves as a feeding point for supplying lighting power to the terminal 15 of the fluorescent lamp 15 fitted therein.

  The cover 3 is often made of resin. It is shaped like a rain gutter that bulges outward, with a “C” cross section. The cover 3 has an upper side and a lower side of the instrument body 1 (the tip of the upper horizontal bar of the “U” shape, the side extending from end to end in the longitudinal direction, and the end of the lower horizontal bar at the end of the longitudinal direction). It is fitted in a shape that covers the edge of the edge). However, it is not permanently or semi-permanently fixed by bonding or screwing or the like, but merely covering the instrument body 1 from the front side.

  And the side plate 12 is covered on the both ends of this lighting fixture. Both of the two side plates 12 have a deep lid shape in which an edge portion rises. Many are made of resin. The flat part which hits the bottom of the deep lid closes the open surfaces on both sides of the instrument body 1 and the cover 3, and covers the edge parts at both ends of the instrument body 1 and the cover 3 at the rising edges. Thereby, the cover 3 and the instrument main body 1 are pressed from the outside so that the cover 3 is not easily removed. This side plate 12 is also only put on the end portions of the instrument main body 1 and the cover 3 so as to be easily attached and detached during maintenance such as lamp replacement. It is not screwed or glued. Such a lighting fixture is described in Patent Document 1, for example.

Registered Utility Model Publication No. 3009378 (paragraph [0002], FIG. 10)

  In the above-described lighting fixture with a cover, the fixing structure of the cover is one of the factors that determine the usability. This will be described below.

  Consider a case in which the above-mentioned lighting fixture is newly attached to an attachment surface such as the vertical surface or the horizontal top surface described above. In this case, first, the instrument body 1 is fixed to the mounting surface with a wood screw or the like. For this purpose, the cover 3 and the fluorescent lamp 10 must be removed in advance. That is, from the state where the lighting fixture is assembled, first, the side plate 12 is removed, and the cover 3 is removed from the fixture main body 1. Next, after removing the fluorescent lamp 10 from the socket 11, the instrument body 1 is screwed to the mounting surface.

  After fixing the instrument body 1 to the mounting surface, the fluorescent lamp 10 is inserted into the socket 11 and the cover 3 is put on the instrument body 1 (this operation is hereinafter referred to as cover attachment). The side plate 12 is covered from both sides (same as side plate mounting).

  Here, let's look at how to proceed when moving from the cover mounting to the side plate mounting. Here, first, the cover 3 is lightly covered on the upper and lower edges of the instrument body 1. Up to this point, you can work with both hands. However, the cover 3 is not fixed to the instrument main body 1 but only covered shallowly, so that it falls when the hand is released.

  Therefore, when the next side plate is mounted, the operation of covering the side plate 12 on the ends of the instrument body 1 and the cover 3 with the other free hand while supporting the cover 3 with one hand, You have to change your left and hand. This task is very difficult. This is because it is difficult to support and balance a long object such as the cover 3 at one point, but in addition to this, another work of side plate mounting must be performed simultaneously. The difficulty is tremendous, and accidents such as falling off the cover are likely to occur. The difficulty of such work and the risk of accidents associated therewith are particularly pronounced when the fluorescent lamp is long and the luminaire is mounted with its longitudinal direction parallel to the floor. For example, when the fluorescent lamp 10 is long such as 40 W (total length: about 1240 mm) and the ceiling has a high mounting surface, it is very difficult because it has to face upward at a high place and spread its hand fully. This makes it easy for accidents to occur.

  Although the above has described the case where a lighting fixture is newly installed, the same difficulty and danger of the same work as described above are also involved when replacing the lamp in an existing lighting fixture. Moreover, in this case, a similar difficult task must be performed twice. In the case of lamp replacement, the cover 3 must first be removed with the luminaire mounted on the mounting surface. This is because the work of removing the cover is added. When removing the cover, the side plate 12 is operated with the other free hand while supporting the cover 3 with one hand. Therefore, the difficulty of work and the risk of accidents are the same as in the case of the cover mounting described above.

  The difficulty of attaching and installing the cover and the risk of accidents associated with it are that the work of supporting the cover is difficult to balance because it supports a long object at a single point. This is because it is caused by the complexity of the operation that requires the operation of removing or attaching the side plate 12 with the hand.

  The difficulty and danger as described above can occur not only in the case where the cover is horizontally long and having a gutter-shaped bulge, but also in the case of a cover having a circular planar shape or a simple flat plate. And, as long as an electric light source is used, not only a straight tube discharge lamp, the work of replacing the light source is indispensable.

  Accordingly, the present invention is a luminaire using an electric light source, which is provided with a cover that covers the light source, and is easy to perform when replacing a light source in a new installation surface or in an existing luminaire. An object is to provide a simple lighting device.

  The lighting fixture of the present invention is a lighting fixture using an electric light source, and serves as a socket for fixing the light source and serving as a power supply point for lighting power to the light source, and a socket holder for fixing the socket. A lighting apparatus having at least a cover for fixing the socket holder and a cover for covering the light source from the side of the illuminated surface, wherein the socket holder and / or the tool body has at least one shaft. The cover is provided with a groove into which the shaft is fitted, and the cover can be opened and closed in a state where it is pivotally supported by a shaft provided in the socket holder and / or the instrument body. To do.

  In the lighting fixture according to the present invention, the cover is pivotally supported by a shaft provided on the socket holder and / or the fixture body. And it is the structure which can be rotated and opened and closed in the state which supported the cover. Therefore, when the instrument body is screwed to the mounting surface or the light source is replaced, it is only necessary to rotate and open the cover. You don't have to remove the cover, and of course you don't have to support it manually. Thereby, according to this invention, the new installation of a lighting fixture and the replacement | exchange operation | work of a light source can be made easy.

  Next, embodiments of the present invention will be described with reference to the drawings.

  In FIG. 1, the disassembled perspective view and perspective side view of the lighting fixture which concern on the 1st Example (Example 1) of this invention are shown. Fig.1 (a) is a figure which shows the place which looked up diagonally upward from lower left, disassembling the state which attached the lighting fixture to the vertical wall surface so that a longitudinal direction might become parallel to a floor surface. This corresponds to the exploded perspective view of the conventional lighting fixture shown above. FIG.1 (b) is a figure which shows the place from the longitudinal direction of a lighting fixture. It corresponds to a perspective side view 7 (b) of a conventional lighting fixture. With reference to FIG. 1 and FIG. 7, the lighting fixture which concerns on a present Example differs from the conventional lighting fixture by the point mainly enumerated below. That is, one shaft 4A is provided for each of the two left and right socket fittings 2A. The point which provided the groove | channel 5A in the both ends of the cover 3A (In addition, the axis | shaft on the right side of a paper surface is hidden and cannot be seen). The shaft 4A is fitted in the groove 5A to support the cover 3A. There is no side plate. In the following, the present invention will be described focusing on the main differences described above.

  The shaft 4A is a metal rod-like object, and protrudes from the respective socket fittings 2A toward the mating socket fitting along the longitudinal direction. The socket metal fittings 2A are made of metal, and the respective socket metal fittings 2A and the shaft 4A are made by bending a single metal plate by pressing. The left and right shafts 4A are positioned on the extension line of the other shaft, and the line connecting the two shafts is parallel to the tube axis of the fluorescent lamp 10.

  The cover 3A is made of resin, and the groove 5A matches the shaft 4A on the socket fitting side at both ends of the lower side of the cover (the lower end of the letter “C” and the side extending from the end in the longitudinal direction). In the position. Looking at the cross section of the groove 5A, as shown in the side view of FIG. 1B, the edge of the lower side of the cover 3A has a shape that rises in a semicircular shape inside, and the inside is hollow. A part of the semicircular portion close to the socket metal fitting 2A is cut off, and an internal hollow portion is connected to the outside to form a groove. The cover 3A can have the above-described structure by molding the resin by extrusion molding or injection molding. Because of this structure, when attaching the cover 3A, the cover 3A is placed so that the lower side is parallel to the fluorescent lamp 10, and the cover 3A is moved in parallel toward the axis 4A of the socket metal fitting. The shafts 4A and the grooves 5A at both ends can be fitted together.

  The cover 3A according to the present embodiment has a small protrusion 6 (see FIG. 3) that protrudes inward on the back side of the upper side (the lower end of the letter “C” and the side extending from end to end in the longitudinal direction). Is provided. The protrusion 6 is connected like a ridge along the upper side of the cover 3A. On the other hand, on the outer side of the upper side of the instrument main body 1A, a ridge-like protrusion 7 is provided that protrudes outward (same as above). As will be described later, after the cover 3A is fitted into the instrument body 1A, the cover-side projection 6 and the instrument body-side projection 7 are caught and the cover 3A is not easily detached. Note that the lower side of the cover 3A is abutted rather than covering the lower side of the instrument body 1A from the outside.

  Next, a procedure for exchanging the lamp in this embodiment will be described. The state where the lighting fixture according to the present embodiment is attached to the wall is shown in FIGS. 2 (a) and 3 (a). Fig.2 (a) is a perspective view when looking up at the lighting fixture diagonally upward from lower left, and Fig.3 (a) is a see-through | perspective side view seen from the longitudinal direction. In FIG. 2A, the fluorescent lamp of the light source is omitted.

  2 (a) and 3 (a), with the luminaire with the cover attached to the wall, the upper side of the cover 3A is lifted up slightly, and the projection 6 on the cover side and the luminaire main body side Unhook the protrusion 7. Since the cover 3A is made of resin, it can be easily removed by the elasticity of the resin. Then, the cover 3A rotates around the line connecting the shafts 4A of the socket metal fittings in the direction indicated by the thick white arrow or the black line with the arrow in the drawing.

  Then, after an intermediate stage as shown in the side view of FIG. 3B, as shown in the side view of FIG. 3C, the cover 3A is fully rotated and opened. Therefore, the fluorescent lamp is removed from the socket as shown in a perspective view when viewed from the lower left of FIG.

  In the previous stage, the cover 3A is always pivotally supported by the fitting of the groove 5A and the shaft 4A on the socket fitting side, so it does not fall even if it is not supported by hand. Also, since there is no side plate removal, the work is easier and easier than ever.

  Thereafter, although not shown, a new fluorescent lamp is fitted into the socket. Then, the cover 3A is rotated upward in the opposite direction as described above, so that the upper side of the instrument main body 1A and the upper side of the cover 3A are abutted. Further, the protrusion 6 on the cover 3A side and the protrusion 7 on the instrument body 1A side are engaged with each other.

  In this series of operations, the cover 3A is rotated upward by hand. However, at this time, since the cover 3A is pivotally supported on the socket metal shaft 4A, it is not necessary to "support the cover so as not to fall". Since you only need to rotate the cover, you can do it with both hands. Even if you release your hand, there is no danger of the cover falling. It is also easy to engage the projection 6 on the cover 3A side and the projection 7 on the instrument body 1A side. If the cover 3A is pushed slightly stronger toward the instrument body 1A side, the projection on the cover side will go over the projection on the instrument body side due to the elasticity of the resin, and both projections will mesh.

  In the present embodiment, the shaft 4A provided on the socket metal fitting 2A may be a separate body from the socket metal fitting and may be structured so as to be screwed to the socket metal fitting. However, in consideration of the fact that the socket metal fitting is usually made of metal, it is preferable to make the socket metal fitting 2A and the shaft 4A from the same single metal plate so as to be integrated. Since the number of parts is the same as before, the number of assembling steps in the manufacturing process such as screwing is not increased, which is advantageous in terms of manufacturing cost. In addition, the cost of parts management will not increase more than ever.

  Although Example 1 described above is an example which does not provide a side plate, the lighting fixture which concerns on Example 2 described below uses the side plate. With reference to FIG. 4 showing a perspective view when the lighting fixture according to the present embodiment is attached to the wall surface and is looked up obliquely upward from the lower left, this embodiment is provided with a side plate 12. This is different from Example 1.

  The side plate 12 has the same deep lid shape as the side plate in the conventional lighting apparatus shown in FIG. It is made of resin and consists of a flat plate part that hits the bottom of the deep lid and a part where the edge rises. The instrument body 1A and the cover 3A are fitted from both left and right sides to cover the open sides of the instrument body 1A and the cover 3A on both sides with flat plate parts, and the edge of the instrument body 1A The cover 3A covers the edge portions at both ends.

  According to the present embodiment, the coupling between the instrument main body 1A and the cover 3A after the assembly becomes stronger than in the first embodiment. In addition, since direct light from the fluorescent lamp 10 is not leaked, it is preferable in terms of appearance.

  In the first and second embodiments, the shaft 4A (see FIG. 1) for supporting the cover is provided on the socket metal fitting 2A (same as above), but in this embodiment, the shaft is provided on the instrument body. FIG. 5 shows a perspective view when the lighting fixture according to the present embodiment is attached to the wall surface and is disassembled and looked up obliquely from the lower left. Referring to FIG. 5, in this embodiment, the shaft is provided on the lower side of the instrument body 1B instead of being provided on the socket metal fitting. One shaft 4B is provided near the socket fitting 2 on the left and right sides of the lower side of the instrument body 1B. The two shafts 4B are located on an extension line of the other shaft, and the line connecting the shafts is parallel to the tube axis of the fluorescent lamp 10. The shaft 4B is made of metal, and is made by bending from the same metal plate as the metal instrument body 1B with a press.

  The cover 3B is provided with a hollow groove 5B having a semi-circular cross section and a semi-circular cross-section having a structure similar to that in the first and second embodiments at a position corresponding to the shaft 4B on the lower side of the instrument body.

  Also in the present embodiment, as in the first and second embodiments, the cover 3B can be rotated around the shaft 4B of the instrument body 1B by fitting the instrument body side shaft 4B into the groove provided in the cover 3B. It can be pivotally supported.

  In the present embodiment, a total of two shafts 4B are provided on the left and right sides of the lower side of the instrument body 1B, but the number of shafts is not limited to this. For example, only one may be provided near the center in the longitudinal direction of the lower side, or three or more may be provided. However, when there is only one shaft, when the luminaire is viewed from the front, a clockwise or counterclockwise moment is applied around the shaft, causing the cover to become unstable or the shaft to be damaged. May be easier. Therefore, it is necessary to take measures such as providing a stopper against the above-described clockwise and counterclockwise rotations on the lower side of the instrument main body 1B away from the axis. In consideration of this, at least two shafts may be provided at positions apart from each other. It would be less likely to cause confusion for the user to provide a plurality of the main body 1B with only the shaft, rather than providing two types of shafts and stoppers having different functions. In the present embodiment, if at least one of the two right and left socket fittings 2 is provided with the same shaft as in the first and second embodiments, only one shaft of the instrument main body 1B is required.

  The present embodiment can be modified as described below. That is, in Example 3, the shafts (see FIG. 5) provided at both ends of the lower side of the instrument main body are collected at the left end or right end of the instrument main body and provided facing the upper side and the lower side. Referring to FIG. 6 showing a partially enlarged view of the instrument body and the cover according to the modification of the present embodiment, in the illumination apparatus of the modification shown in the figure, an inward shaft 4C is provided at the left end of the lower side of the instrument body 1C. Provided. A shaft 4C is also provided inward at the left end of the upper side of the instrument body. The two upper and lower shafts 4C are located on an extension line of the other shaft. On the other hand, the cover 3C is provided with one groove 5C protruding inward at the left end of the upper side and the left end of the lower side. Both of the two grooves 5C have a cylindrical structure in which a part of the circumference is cut.

  In this modification, when the instrument body side shaft 4C is fitted into the cover side groove 5C, the cover 3C is always pivotally supported in a state where it can rotate around the upper and lower two shafts 4C. Therefore, when replacing the fluorescent lamp, it is only necessary to rotate and open and close the cover 3C, and it is not necessary to support the opened cover so that it does not fall.

  Here, in the above-described modification, the shaft 4C is provided in the instrument body, but the shaft may be provided in the socket metal fitting. In this case, if the mechanical strength of the shaft and the groove portion of the cover is sufficient, it is possible to support one point with a single shaft.

  In addition, although all the examples and modifications so far use a cover having a horizontally long square when viewed from the illuminated surface (surface illuminated by the lighting fixture) side, the structure of the cover is Not limited to this. The operation principle of the present invention is that the cover is pivotally supported by a shaft provided on the socket metal fitting or the instrument body so as to be opened and closed. Therefore, the cover does not have to be horizontally long, and further, even with a cover having a planar shape other than a quadrangle, such as a circle, the effects of the present invention can be obtained. The cross section of the cover exemplifies a “C” -shaped rain gutter-like shape, but may be a shape formed by a straight line such as a “U” -shaped. Furthermore, it may be a simple flat plate without swelling.

  Moreover, although the example which used the straight tube | pipe type fluorescent lamp for the light source was described, the light source is not restricted to this. The shape of the light source may not be a straight tube as long as the shaft support structure of the cover and the shaft can be realized. For example, a discharge lamp such as an ultraviolet lamp that does not use a phosphor can also be used. Furthermore, instead of a discharge lamp, another electric light source such as an incandescent lamp may be used.

  In addition, although the example in which the instrument main body and the socket metal fitting are made of metal has been described, it may be made of resin as long as it has sufficient mechanical strength. The instrument body and the socket holder can be made of resin and the shaft can be integrally provided by extrusion molding or injection molding.

  And although the case where it was the structure where a lighting fixture is fixed to a vertical wall was described as an example, also in the lighting fixture of a structure fixed to a horizontal top surface, such as a ceiling, the same operation effect as an example can be acquired. it can. Furthermore, the same applies to a hanging-type lighting fixture in which the fixture body is suspended from the ceiling with a chain or a cord, or a stand-type lighting fixture in which a column is attached to the fixture body and held in a semi-fixed state. The effect is obtained.

  INDUSTRIAL APPLICABILITY The present invention is a lighting fixture that uses a straight tube discharge lamp as a light source, and is particularly effective when used for a lighting fixture having a horizontally long cover that covers the light source from the illuminated surface side.
