Description

This invention relates to a light source unit and a lighting fixture.

2. Description of the Related Art Conventionally, in square lighting fixtures that are installed on a mounting base such as a ceiling, there are some that have a light source unit equipped with a power source attached to a fixture body that is attached to a mounting base.
The lighting fixture described in Patent Document 1 is a lighting fixture in which a light source unit including a light-emitting part, a light source mounting part having a reflecting part, a diffusion panel, and a frame part for holding the diffusion panel is attached to a main body part fixed to a mounting part. This light source unit is disposed in the frame part so that a power supply unit for turning on the light-emitting part is located to the side of the reflecting part.

Japanese Patent Application Publication No. 2014-165143

The light source unit of the lighting fixture described in Patent Document 1 also has a design function in which the frame portion covers the peripheral portion of the light source mounting portion. However, the light source mounting part includes a reflective part, and the frame part itself also includes a power supply unit, so the frame part is formed large, which poses a problem in terms of design.

Further, since the diffusion panel is held between the frame portion and the end of the reflection portion, there is a possibility that the diffusion panel is pressed and damaged. Furthermore, there is a possibility that problems due to differences in thermal expansion coefficients, such as deformation such as warping, and abnormal noises such as squeaks, may occur.

In addition, while the reflector improves the efficiency of light emitted in the forward direction, the reflector and frame prevent light from being emitted in the lateral direction of the frame. As a result, the sides of the lighting fixture and the area to which it is attached are likely to become dark.

Another issue with conventional square light source units was that the cover was difficult to attach to the mounting part.

An object of the present invention is to provide a light source unit that suppresses problems caused by differences in thermal expansion coefficients.

The light source unit of the present invention comprises:
a module mounting portion including a front mounting portion on which a light emitting module is mounted and a side mounting portion rising from a side of the front mounting portion toward the side on which the light emitting module is mounted;
a translucent cover portion having a cover front portion and a cover side portion rising from a peripheral edge of the cover front portion and disposed on the module mounting portion so as to cover the light emitting module;
Equipped with
The cover side portion is
The cover has a protrusion at an end in a rising direction rising from the periphery of the front surface thereof, which extends in the rising direction from the end and serves as an attachment mechanism for attaching the cover to the module attachment portion.

In the light source unit of the present invention, the convex portion covers the end of the mounting side portion, so the end of the mounting side portion is not visible. This has the effect of improving the design of the light source unit.

The cover section 1300 is formed such that the outer dimensions of the four cover side sections 1320 are smaller than the inner dimensions of the four mounting side sections 1220 of the module mounting section 1200.

Thus, the cover part 1300 has a plate-shaped cover front part 1310 and a wall-shaped cover side part 1320 rising from the periphery of the cover front part 1310. The cover part 1300 is box-shaped with an opening (ABCD) (FIG. 2) formed by the end of the cover side part 1320 in the rising direction 1320a, and transmits light emitted by the light-emitting module 1100. As shown in FIG. 2, the cover part 1300 is disposed on the module mounting part 1200 so that the opening (ABCD) covers the light-emitting module 1100. The cover part 1300 also has a cover fixing hole 1322, which is a fixed locking part 9100 that receives the cover fixing claw part 1420 by inserting the cover fixing claw part 1420 in the insertion direction 1310a, which is the direction from the inside of the box shape to the outside and along the cover front part, on the inner surface 1320b of the cover side part 1320 that is the inside of the box shape.

(Fixing tool 1400)
It is fixed to the module attachment part 1200. The fixture 1400 (FIG. 6) has a cover fixing claw part 1420 for disposing the cover part 1300 on the module mounting part 1200. The fixture 1400 is disposed on the module mounting section 1200 and holds the cover section 1300. In this embodiment, the fixture 1400 is a metal fitting (fixing metal fitting), but it does not have to be metal, but may be made of resin or carbon fiber material. The fixture 1400 has a substantially rectangular shape, and is arranged in pairs with a fixed front part 1410 that abuts and is fixed to the mounting front part 1210 of the module mounting part 1200, with an interval from the side of the fixed front part 1410. An L-shaped cover fixing claw portion 1420 is provided. As shown in FIG. 6, the cover fixing claw part 1420 is engaged with the cover fixing hole 1322 of the cover part 1300 through the insertion hole 1211, thereby fixing the cover part 1300.

(Lighting device 1500)
The lighting device 1500 receives power from outside the lighting fixture 1 and supplies power to the light-emitting module 1100 to light it. The lighting device 1500 is disposed on the opposite side of the surface of the mounting front portion 1210 to which the light-emitting module 1100 is attached.

(Spring receiving part 230L)
As shown in FIG. 9, an arcuate portion 212 into which an arcuate portion 212M of a mounting spring 210M is inserted slides on the spring receiving portion 230L. Two spring receiving parts 230L are arranged in parallel on the mounting front part 1210 so as to correspond to the mounting springs.

The claw portion 240L is fixed to the mounting front portion 1210 by hooking the claw tip portion 241L onto the opening edge portion 221M-1 of the hook receiving portion 220M (FIG. 11). Two claw portions 240L are arranged in parallel on the mounting front portion 1210 to correspond to the hook receiving portion 220M.

(Assembling light source unit 1000)
Next, a method for assembling the light source unit 1000 will be explained using FIG. 7. 7 is a cross section with the normal line in the X direction of FIG. 6, and corresponds to a cross section cut through the cover fixing hole 1322 on the left side of FIG. 6 (closer to arrow X).
(1) First, the module attachment part 1200 to which the light emitting module 1100 is attached is arranged so as to cover the opening (ABCD in FIG. 2) of the cover part 1300. At this time, the module attachment part 1200 is arranged so that the light emitting module 1100 faces the cover front part 1310 and the attachment side part 1220 is on the outside of the cover side part 1320 ((a) in FIG. 7).
(2) Next, the fixture 1400 is inserted into the cover fixing hole 1322 of the cover part 1300 through the insertion hole 1211 of the module attaching part 1200.
From the state shown in FIG. 7A, the fixing tool 1400 is inserted into the insertion hole 1211 from the tip of the cover fixing claw part 1420. At this time, by inserting the fixing tool 1400 while rotating it (rotation direction shown in FIG. 7(c); V1 and V2 are directions of the fixed front part 1410), the tip of the cover fixing claw part 1420 fixes the cover. While being inserted into the hole 1322, the fixed front part 1410 comes into contact with the mounting front part 1210 ((c) in FIG. 7). After the fixed front section 1410 comes into contact with the mounting front section 1210, the fixture 1400 is fixed to the module mounting section 1200 using screws 10 or the like.
(3) The above steps are performed at predetermined locations (four locations in FIG. 5) where the fixture 1400 is installed, and the cover portion 1300 is fixed to the module attachment portion 1200. As described above, in the light source unit 1000, the module attachment part 1200 to which the light emitting module 1100 is attached is provided from the opening side of the cover part 1300, and the fixture 1400 is inserted into the cover fixing hole of the cover part 1300 through the insertion hole 1211. Assemble by inserting into 1322. Therefore, the work can be done from one direction (the direction from the module attachment part 1200 toward the cover part 1300 in FIG. 5), and assembly can be performed easily. Further, as shown in FIGS. 4A and 7C, in the light source unit 1000, the mounting side surface portion 1220 is arranged outside the cover fixing claw portion 1420. Therefore, the mounting side surface part becomes a design part (the role of a decorative board), and the mounting mechanism (cover fixing claw part 1420, convex part 1321, cover fixing hole 1322, etc.) is hidden by the mounting side part 1220, which becomes a design surface. Since there is no such thing, the design quality is improved.
(4) As shown in FIGS. 6 and 7, the fixture 1400 has a cover fixing claw part 1420 for holding the cover part 1300. The module attachment part 1200 has an insertion hole 1211 through which the cover fixing claw part 1420 can pass. The cover part 1300 is fixed by a cover fixing claw part 1420 inserted in an insertion direction 1310a (FIG. 7(c)), which is a direction from the inside of the box shape to the outside and along the cover front part 1310. It has a cover fixing hole 1322 which is a fixed locking part 9100 that receives a claw part 1420. The fixing tool 1400 is in a state in which a part of the cover fixing claw part 1420 is inserted into the cover fixing hole 1322, and a part of the remaining part that is not inserted into the cover fixing hole 1322 other than the part passes through the insertion hole 1211. It is fixed to the module attachment part 1200 (FIG. 7(c)).

The dimensional relationship between the module mounting part 1200 and the cover part 1300 will be described with reference to FIG. 4. FIG. 4(a) is a cross-sectional view of the light source unit 1000, and FIG. 4(b) is a schematic diagram of the light source unit 1000 after assembly is completed. The positional relationship between the module mounting part 1200 and the cover side part 1320 is as shown in FIG. 4. That is, the distance between the mounting front part 1210 and the convex part 1321 of the cover side part 1320 is gap A (dimension A), and the distance between the mounting front part 1210 and the end part other than the convex part 1321 of the cover side part 1320 is gap B (dimension B). In addition, the mounting side part 1220 covers the cover side part 1320 so as to cover the cover fixing claw part 1420. This gap A is, for example, about 1 mm, and the gap A is a dimension that suppresses the cover part 1300 from expanding due to heat and coming into contact with the mounting front part 1210 and rubbing. In addition, the gap B is formed larger than the gap A. The gap B prevents the end of the cover side portion 1320 of the cover portion 1300 from interfering with the mounting front portion 1210 when a molding tolerance occurs in the cover portion 1300 as shown by the dotted line A in FIG. 4B. The gap B prevents the end of the cover side portion 1320 from interfering with the mounting front portion 1210 due to molding and applying a load to the cover fixing claw portion 1420. In addition, the mounting side portion 1220 covers the cover side portion 1320, thereby preventing the end of the cover side portion 1320 from appearing on the side when a molding tolerance occurs in the cover portion 1300 as shown by the dotted line B in FIG. 4B, thereby maintaining the design.

As described above, the fixing device 1400 is fixed to the module mounting part 1200 and holds the cover part 1300 with a gap in the rising direction 1320a between the end of the cover side part 1320 of the cover part 1300 and one surface 1210a of the mounting front part 1210. Also, as shown in FIG. 4, the cover side part 1320 is formed so as to be convex in the rising direction 1320a from the end forming the opening (ABCD) (FIG. 2), and has a convex part 1321 in which a cover fixing hole 1322, which is a through hole, is formed as the fixed engagement part 9100. The mounting front part 1210 has a gap A in the rising direction 1320a between one surface 1210a and the convex part 1321.

(Attachment of light source unit 1000 to appliance main body 100)
Next, the attachment of the light source unit 1000 to the instrument main body 100 will be explained using FIG. 12. FIG. 12 corresponds to a cross section taken at the center of the opening edge 221M-1 in FIG. (1) First, the light source unit 1000 inserts the claw tip 241L of the claw into the opening 221M of the hook receiver 220M provided in the instrument main body 100, and hooks it on the opening edge 221M-1.
(2) Next, the mounting spring disposed on the instrument body 100 is elastically deformed as shown in FIG. Hook it to -1.
(3) Next, from the state shown in FIG. 12(b), by pushing the light source unit 1000 toward the instrument main body 100, the arc-shaped portion 212M of the mounting spring touches the opening edge 231L-1 of the spring receiver 230L. It slides ((c) in FIG. 12).
At this time, the lighting device 1500 is housed inside the fixture main body 100, and the surface of the mounting front section 1210 of the light source unit 1000 opposite to the surface on which the light emitting module 1100 is disposed is the light source receiver of the fixture main body 100. It comes into contact with 122. As a result, the light source unit 1000 is fixed to the instrument main body 100 ((d) in FIG. 12).

<＊＊＊Explanation of effect＊＊＊>
(1) In this embodiment, a module mounting portion 1200 including a light emitting module 1100 and a lighting device 1500 is attached to a substantially box-shaped cover portion 1300 with an opening on one side (ABCD in FIG. 2). This is a light source unit 1000 arranged so as to block the area.
The light source unit 1000 is assembled by inserting the fixture 1400 into the cover fixing hole 1322 of the cover part 1300 through the insertion hole 1211 of the module attaching part 1200, so that the work can be done from one direction, making assembly easy. can.
(2) Furthermore, in the light source unit 1000, since the cover part 1300 is fixed to the module attachment part 1200 with the gap B provided, the molding of the cover part 1300 can be absorbed.
(3) In addition, in the light source unit 1000, the fixture 1400 fixes the cover part 1300 to the module mounting part 1200 with a gap A so that the cover part 1300 does not come into contact with the module mounting part 1200. The generation of squeaks can be suppressed.
(4) Furthermore, in the light source unit 1000, since the cover part 1300 is fixed to the module attachment part 1200 by the fixture 1400, the sides of the cover part 1300 are not covered. Therefore, light from the light emitting module 1100 can be emitted from the side.

In addition, in this embodiment, the combination of the attachment spring 210M, the hook receiving part 220M, the spring receiving part 230L, and the claw part 240L with respect to the fixing mechanism 200 is described, but the combination of the mounting spring and the spring receiving part 230L It may be due solely to Further, the spring receiving portion 230L and the claw portion may be provided on the instrument main body portion 100, and the attachment spring and the hook receiving portion may be provided on the light source unit 1000.

The module attaching part 1200 has a decorative part 9200 that covers the position of the cover fixing hole 1322, which is the fixed locking part 9100, from the outside of the cover side part 1320. As shown in FIGS. 4, 7(c), etc., the decorative portion 9200 includes a mounting side surface portion 1220 that rises from the other surface 1210b toward the one surface 1210a on the side 1210-1 of the mounting front portion 1210. It is. Since the mounting side surface portion 1220 serves as the decorative portion 9200, the tip of the cover fixing claw portion 1420 can cover the exposed state from the cover side surface portion 1320.

Embodiment 2.
13 to 16, in a second embodiment, a light source unit 2000 including a cover section 2100 that is a modification of the cover section 1300 described in the first embodiment will be described. Note that configurations similar to those in Embodiment 1 are given the same reference numerals as in Embodiment 1, detailed explanations are omitted, and different configurations will be described.

As shown in Figures 13 and 14, the light source unit 2000 includes a cover section 2100 that is generally box-shaped with one side open, a light-emitting module 1100, and a lighting device 1500, a module mounting section 1200 that is arranged to cover the opening of the cover section 2100, and a fixture 1400 that fixes the cover section 2100 to the module mounting section 1200.

(Outer convex part)
The cover part 2100 has a generally box-like shape with one side open, and the surface facing the opening is the cover front part 2110 (FIG. 14), and the side is the cover side part 2120 (FIG. 14). The cover side part 2120 has an outer convex part 2130 that protrudes in a convex shape from the outer surface 2120c that is the outside of the box shape. As shown in FIG. 14, the outer convex part 2130 is provided to face the end of the mounting side part 1220 so as to cover the end of the mounting side part 1220 of the module mounting part 1200. The outer convex part 2130 covers the end of the mounting side part 1220, which is the decorative part 9200, in the direction from the other surface 1210b toward the one surface 1210a, so that the end of the mounting side part 1220 does not appear on the design surface in the front direction. This improves the design. Furthermore, this outer convex portion 2130 is particularly effective for end treatment when the module mounting portion 1200 is formed by processing an already surface-treated member (such as a color steel plate) by cutting, bending, or the like.

In this embodiment, the cover portion 2100 has an outer convex portion 2130, which improves the design of the light source unit 2000.

As a modified example of the outer convex portion 2130, a cover portion 2100-1 as shown in FIG. 15 may be used. The cover portion 2000-1 has an inclined portion so that the cover side portion 2120-1 functions as an outer convex portion. As an example of a modified example, the cover side portion 2120-1 has an inclined portion, but the inclined portion may be formed in a curved shape.

Further, in both Embodiment 1 and Embodiment 2, the cover fixing hole 1322 and the cover fixing hole 2121 are through holes, but as shown in FIG. The cover part 2100-2 may have a groove-shaped cover fixing groove 2121-1 as the cover fixing hole. Furthermore, by providing a grain or the like at the tip of the cover fixing claw 1420, it is possible to prevent the tip of the cover fixing claw 1420 from being visible through the cover side surface 2120.
