Description

  The present invention relates to a luminaire including a luminaire main body including a lamp and the like, and a heat shield and a canopy that are integrally fixed to an illuminating frame.

  2. Description of the Related Art Conventionally, in a lighting fixture, a fixing bracket using a screw is used to fix a lighting fixture body including a lamp, a canopy, and a heat shield with respect to a lighting frame. That is, the fixing bracket is made of an angle material having an L-shaped cross section, and on one surface of the angle material, a luminaire main body including a lamp or the like or a heat shield (hereinafter referred to as “light luminaire main body”). .) Is integrally drilled, and a fixing hole is formed on the other surface for fixing a lighting fixture body or the like integrated with the fixing bracket to the lighting frame. Is. Therefore, when attaching the luminaire main body or the like to the lighting frame, the luminaire main body or the like is first attached using the attachment hole on one surface of the fixing metal fitting so as to be integrated with the fixing metal fitting. Then, using the fixing hole drilled on the other surface of the fixture that is integrated with the luminaire main body, etc., the luminaire main body etc. and the illuminating frame are integrated with each other. The lighting fixture is configured by being fixed.

  However, the fixing bracket used when configuring the conventional lighting fixture is to fix the fixing fixture integrated with the lighting fixture main body or the like to the lighting frame by screwing using a fixing hole. Therefore, it is necessary to limit the screw foot of the screw to a certain length so that the screw for fixing the fixing bracket integrated with the lighting fixture body etc. to the lighting frame does not damage the lighting frame. As a result, the strength required to fix the lighting fixture body or the like to the lighting frame cannot be secured, the fixing bracket is not sufficiently fixed to the lighting frame, and the lighting fixture body or the like may fall.

  In addition, a plurality of screws are required to fix the fixture that integrally attaches the luminaire body or the like to the illumination frame. As a result, the number of parts is increased, and the increase in the number of parts also leads to a decrease in workability at the time of assembling work, leading to an increase in product cost as a lighting fixture.

  In addition, when a conventional lighting fixture is used outdoors or the like, if rainwater or the like enters the lighting fixture main body or the like, it may cause corrosion or electric leakage due to rust. Therefore, in order to prevent the intrusion of rainwater and the like, the lighting fixture is required to have a sealing property. Therefore, a seal such as rubber is used for the opening of the lighting fixture, and the sealing property is secured by deformation of the packing. . However, the use of a separate packing causes an increase in the number of parts, and the packing itself is deformed unevenly and easily breaks, so that the sealing performance may be insufficient.

  The problem to be solved is that the number of parts required to fix the lighting fixture body etc. to the lighting frame is large, which leads to an increase in product cost due to an increase in parts cost and assembly workability, as well as rainwater etc. It is the point that the prevention of the occurrence of rust and electric leakage due to infiltration becomes insufficient.

  For this purpose, when the lighting frame constituting the lighting fixture, the lighting fixture main body including the lamp and the canopy are fixed together, the L-shaped locking edge of the canopy is engaged with the locking upper flange of the fixing bracket. The locking lower flange of the fixing bracket is in the locking groove of the lighting frame, and the L-shaped locking edge of the canopy engaged with the locking upper flange of the fixing bracket is in the locking step of the lighting frame, respectively. The fixing bracket and the canopy are fixed to the lighting frame by inserting and fitting the locking vertical flanges of the two opposing heat shield surfaces in the fixing bracket to the locking vertical grooves of the lighting frame, respectively. The lighting fixture body is attached via the mounting flange of the fixing bracket to constitute the lighting fixture.

  Furthermore, since the fixture with a U-shaped cross section used to fix the luminaire main body to the lighting frame is arranged along the inside of the lighting frame, the heat shield conventionally provided separately is used. The plate can be omitted, and the fixing bracket is fixed in the lighting frame by its own elasticity, so the screws required for fixing to the conventional lighting frame can be omitted, so the number of parts As a result, the assembly workability is improved, so that the product cost can be reduced.

  In addition, when the luminaire is used outdoors, the vertical locking edge of the canopy partially covers and covers the left and right edges of the illumination frame opening. Rainwater that has entered the space passes between the fixing bracket that also serves as a heat shield and the inner wall surface of the lighting frame, and is discharged outside the lighting fixture. It is possible to reduce the number of parts by omitting the packing, and to improve the sealing performance in the lighting fixture to prevent rusting and leakage.

  As described above, in the manufacture of the lighting fixture, the canopy and the lighting fixture main body and the lighting frame can be fixed easily and reliably, and the components necessary for fixing the canopy, the lighting fixture main body and the lighting frame Since it reduces the number of points and improves the water resistance against rainwater, it has an excellent effect of reducing the product cost as a lighting fixture and significantly improving the durability.

  The present invention will be described with reference to embodiments shown in the drawings. Shown in (1) is a lighting fixture fixed to a wall surface (3) or the like by a screw (2) or the like which is an embodiment of the present invention. An illuminating device (1) according to an embodiment of the present invention includes an illuminating frame (4), a luminaire main body (5) including a lamp, a canopy (6) covering the upper portion of the illuminating frame (4), a heat shield. It consists of a fixture (7) that also serves as a plate. (See FIGS. 1 to 3).

  First, as shown in FIGS. 4 and 5, the illumination frame (4) is formed by joining, for example, three flat plates into a U-shaped cross section. A locking step (4a) is formed on the inner side of the upper edge (4 ') of the illumination frame (4). The engagement step (4a) is recessed downward along the illumination frame (2) having a U-shaped cross section. It is what you are doing. In addition, a locking groove (4b) is disposed in parallel with the locking step (4a) at the lower part of the inner wall surface (4 ″) of the U-shaped lighting frame. In the shape of the lighting frame (4), in the vicinity of the opening side end portions of the two frame surfaces (4d) and (4d ′) arranged so as to face each other, vertically locked in the vertical direction so as to face each other. A groove (4c) is formed.

  Next, as shown in FIGS. 6 and 7, the canopy (6) has the tip of the three edges inward in the three adjacent edges of the four edges of the rectangular plate. It is bent to form an L-shaped locking edge (6a) having an L-shaped cross section. The remaining one edge is formed with a vertical locking edge 6b that hangs downward. The shape of the canopy (6) may be rectangular according to the design.

Further, as shown in FIGS. 8 and 9, the fixing metal member (7) is formed, for example, by bending one metal plate into a U-shaped cross section. That is, the three adjacent surfaces are perpendicular to each other as heat shield surfaces (7a), (7b), and (7c) that shield heat so that heat generated from the luminaire body (5) is not transmitted to the lighting frame (4). It is arranged. Therefore, the fixing bracket (7) has elasticity so that the two heat shield surfaces (7b) (7c) arranged so as to face each other in the opening direction can be expanded left and right. .
The upper edge (7 ') of the three heat shield surfaces (7a) (7b) (7c) of the fixing bracket (7) is engaged with the L-shaped locking end edge (6a) of the canopy (6). In addition, the locking upper flange (7e) that is locked to the locking step (4a) of the lighting frame (4) via the L-shaped locking edge (6a) is bent outward. Is formed. Among these, on the heat shield surfaces (7b) and (7c) facing each other, the canopy support portion (upwardly standing upright so as to support the canopy (4) from below with the locking upper flange (7e)). 7d) is formed. By providing the canopy support portion (7d), the upper locking flange (7e) provided on the heat shield surfaces (7b) (7c) facing each other is limited to the vicinity of the opening side end portion. Therefore, when the L-shaped locking end edge (6a) of the canopy (6) and the locking upper flange (7e) are engaged, the heat shielding surfaces (7b) (7c) are resisted against the elasticity. Since it is not necessary to move the heat shield surfaces (7b) and (7c) in the closing direction, the assembly is easy.
On the other hand, the lower edge (7 ″) of the three heat shield surfaces (7a) (7b) (7c) of the fixing bracket (7) is inserted into the locking groove (4b) of the illumination frame (4), The lower locking flange (7f) to be locked is formed so as to bend outward with respect to the heat shield surfaces (7a), (7b) and (7c). The two heat shield surfaces (7b) and (7c) facing each other on the surfaces (7a), (7b), and (7c) have left and right engagements that are engaged with the engagement vertical grooves (4c) of the illumination frame (4). The vertical flange (7g) is formed so as to be bent outward with respect to the heat shield surfaces (7b) (7c).
Further, of the three heat shield surfaces (7a), (7b), and (7c) of the fixing bracket (7) formed in a U-shaped cross section, two heat shield surfaces (7b) (7b) ( At the side edge of 7c), a mounting flange (7h) in which a mounting hole (7i) to which the luminaire body (5) is integrally mounted is disposed is provided on the heat shield surfaces (7b) (7c). It is formed so as to be bent inward.

As described above, since the canopy (6), the fixing bracket (7), and the illumination frame (4) constituting the lighting apparatus according to the embodiment of the present invention are formed, the lighting apparatus according to the embodiment of the present invention. In configuring (1), the following is performed.
First, the operator holds the fixing bracket (7) by gripping, for example, the vicinity of the opening-side end portions of the opposing heat shield surfaces (7b) and (7c) of the fixing bracket (7) having a U-shaped cross section with a hand or the like. The opening width of the fixture (7) is made narrow by using elasticity. (See FIG. 12) In this state, the L-shaped locking end edge (6a) provided on the three edges of the canopy (6) and the heat shield surfaces (7a) (7b) (7c) of the fixing bracket (7) The canopy (6) and the fixture (7) are fixed by engaging the respective locking upper flanges (7e) provided on the upper edge (7 ') of the base plate. At this time, the canopy support part (7d) formed on the upper edge (7 ') of the fixing bracket (7) supports the canopy (6) from below.

Next, the fixing metal (7) integrated with the canopy (6) and the opening side of the illumination frame (4) are set in the same direction, and the heat shielding surfaces of the fixing metal (7) at positions facing each other. (7b) The locking lower flange (7f) formed on the lower edge (7 ″) of the (7c) is connected to the locking step (4a) on the inner wall surface (4 ″) of the lighting frame (4). Slide along the locking grooves (4b) arranged in parallel. At this time, the lower surface of the L-shaped locking edge (6a) of the canopy (6) simultaneously engaged with the locking upper flange (7e) of the fixing bracket (7) is the locking step (4a) of the lighting frame (4). ).
Further, the gripping force to the heat shield surfaces (7b) and (7c) is adjusted (see FIG. 12), and the fixing bracket (7) is folded outward from the two heat shield surfaces (7b) and (7c) facing each other. When the bent left and right locking vertical flanges (7g) are locked in the locking vertical grooves (4c) of the lighting frame (4) by the elasticity of the heat shield surfaces (7b) (7c), the fixing bracket (7) All the lower locking flanges (7f) on the lower edge (7 ″) are locked in the locking grooves (4b). The L-shaped locking end edge (6a) of the canopy (6) engaged with the flange (7e) is placed on the locking step (4a) of the illumination frame (4), and is expanded. The locking vertical flange (7g) formed on the two heat shield surfaces (7b) and (7c) at the opposite positions of the fixed metal fitting (7) is also formed on the inner wall surface (4 ") of the lighting frame. Fitted in Tometatemizo (4c), said fixing bracket (7) is to be securely fixed to the lighting frame (4) in.

In addition, the luminaire main body (5) including a lamp and the like is integrally attached to the fixture (7) having a U-shaped cross section. That is, the luminaire main body (5) is guided into the fixing bracket (7) having a U-shaped cross section, and is fixed to the mounting hole provided in the rear surface direction of the luminaire main body (5). The mounting hole (7i) of the mounting flange (7h) of the metal fitting (7) is screwed and fixed with a screw (8).
From the above, the luminaire main body (5) is simply and reliably fixed in the illumination frame (4) together with the canopy (6) by the fixing bracket (7).

  Furthermore, in the lighting fixture (1) constructed by the above procedure, the opening side edge of the locking step (4a) of the lighting frame (4) is sealed by the vertical locking edge (6b) of the canopy (6). While being stopped, a space (9) is formed between the illumination frame (4) and the fixture (7) (see FIG. 2). That is, by installing the luminaire (1) outdoors, the vertical locking end of the canopy (6) is provided on the wall surface (3) side even when rainwater hits the luminaire (1) due to rain or the like. Since the edge of the locking step (6a) is sealed by the edge (6b), the rainwater does not enter the canopy (6). The space (9) serves as a water passage from the canopy (6) to the locking groove (4b) in the inner wall surface (4 ″) of the lighting frame (4). 1) Even if rainwater or the like enters from the gap of the canopy (6) fixed to the top of the lighting frame (4) with respect to the inside, the rainwater that has entered does not enter the fixing bracket (7), and illumination It passes through the space (9) between the inner wall surface (4 ″) of the frame and the fixing bracket (7) and reaches the engaging groove (4b) of the inner wall surface (4 ″) of the lighting frame. As a result, the luminaire main body (5) to be disposed inside the fixture (7) inside the luminaire (1) Since it never touches rainwater that has entered, it can prevent rusting and leakage.

When disassembling the luminaire main body (5), the fixing bracket (7), the canopy (6), and the illumination frame (4) constituting the luminaire (1), the following is performed.
That is, first, the luminaire main body (5) and the fixing bracket (7) that are integrally attached can be separated from each other by releasing the screw (8) that integrates them together. Next, an operator grasps the opening of the fixing bracket (7) to reduce the width, and the left and right locking vertical flanges (7g) of the fixing bracket (7) and the right and left locking verticals of the lighting frame (4) are reduced. While releasing the engagement with the groove (4c), the fixing bracket (7) is pulled in the opening direction of the lighting frame (4), and the fixing bracket (7) integrated with the canopy (6) is attached to the lighting frame. Remove from (4). After that, the operator again reduces the width by gripping the opening of the fixing bracket (7), whereby the upper edges of the two heat shield surfaces (7b) and (7c) facing each other of the fixing bracket (7). The engagement between the locking upper flange (7e) formed on (7 ') and the L-shaped locking edge (6a) of the canopy (6) is released.
