Description

The present invention relates to a lighting fixture.

The LED lighting device described in Patent Document 1 is composed of a substrate, an LED light-emitting element arranged on the surface of the substrate, and a hollow casing through which the substrate is inserted. Of the four sides of the hollow casing, one side parallel to the surface adjacent to the back surface of the substrate is a diffusion surface that diffuses and transmits light from the LED light-emitting element. In addition, of the four sides of the hollow casing, two sides perpendicular to the surface adjacent to the back surface of the substrate are reflective surfaces that reflect the light from the LED light-emitting element toward the diffusion surface without transmitting it.

Utility Model Registration No. 3200708

However, in the LED lighting device described in Patent Document 1, the brightness of the diffusion surface may be too high because the light from the LED light-emitting element is not transmitted through the reflective surface. In addition, if the LED lighting device is attached to an attachment surface such as a ceiling, the brightness of the attachment surface may be too low because the light from the LED light-emitting element is not transmitted through the reflective surface. Therefore, there is a possibility that the difference between the brightness of the LED lighting device and the brightness of the attachment surface may become large.

The present invention was made in consideration of the above problems, and its purpose is to provide a lighting fixture that can reduce the difference between the brightness of the lighting fixture itself and the brightness of the mounting surface.

The lighting device disclosed in this application can be attached to a mounting surface. The lighting device includes a light source, a cover, a transmissive portion, and a reflective portion. The light source includes a light-emitting element that emits light. The cover covers the light source. The transmissive portion faces the light-emitting element via the cover. The reflective portion is adjacent to the transmissive portion. The transmissive portion transmits a portion of the light that has passed through the cover. The reflective portion reflects a portion of the light that has passed through the cover toward the mounting surface.

In the lighting device disclosed in this application, it is preferable that the reflective portion is inclined with respect to the transmissive portion and forms an obtuse angle with respect to the transmissive portion.

In the lighting device disclosed in this application, it is preferable that the transmission portion is approximately parallel to the substrate.

In the lighting device disclosed in the present application, it is preferable that the transmission section has a first transmission area that transmits the light and a first reflection area that reflects the light.

In the lighting device disclosed in this application, it is preferable that the cover includes an inclined portion that is inclined away from the reflective portion with respect to the transmissive portion.

The lighting device disclosed in the present application preferably further includes a holding section. The holding section preferably holds the cover and the reflecting section. The reflecting section and the transmitting section are preferably integrally molded.

This invention makes it possible to reduce the difference between the brightness of the lighting fixture and the brightness of the mounting surface.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or equivalent parts are denoted by the same reference symbols and will not be described repeatedly. In the present specification, in order to facilitate understanding of the invention, the description may be made with reference to the mutually orthogonal X, Y, and Z directions. For example, the X and Y directions are parallel to the horizontal direction, and the Z direction is parallel to the vertical direction. However, the X and Y directions may be parallel to a direction other than the horizontal direction, and the Z direction may be parallel to a direction other than the vertical direction. In the following, in this embodiment, when the lighting device 1 is attached to the mounting surface Wa, the Z direction is parallel to the first direction D1, the Y direction is parallel to the second direction D2, and the X direction is parallel to the third direction D3. That is, in this embodiment, the first direction D1, the second direction D2, and the third direction D3 are mutually orthogonal.

First, the lighting fixture 1 of this embodiment will be described with reference to Figures 1 and 2. Figure 1 is a perspective view showing the lighting fixture 1 according to this embodiment. Figure 2 is an exploded perspective view of the lighting fixture 1 according to this embodiment.

The lighting fixture 1 of this embodiment is used, for example, as a base light or indirect lighting. The lighting fixture 1 of this embodiment can be attached to a mounting surface Wa (see FIG. 3), such as a ceiling surface, a wall surface, or a floor surface. The ceiling surface may be an inclined ceiling surface. Alternatively, the lighting fixture 1 can be directly attached to the mounting surface Wa and attached to the mounting surface Wa. Alternatively, the lighting fixture 1 can be hung and attached to the mounting surface Wa. In this specification, the lighting fixture 1 is inserted into a recessed hole formed in the ceiling surface as the mounting surface Wa and attached to the mounting surface Wa as an example. That is, FIGS. 1 and 2 show the lighting fixture 1 when viewed from diagonally below. However, these orientations do not limit the orientation of the lighting fixture 1 of the present invention during manufacturing, installation, and use.

As shown in Figs. 1 and 2, the lighting fixture 1 has a substantially rectangular parallelepiped shape. Specifically, in this embodiment, the lighting fixture 1 has a substantially rectangular parallelepiped shape that is elongated in the third direction D3, for example. The lighting fixture 1 includes a light distribution member 5, a cover 30, a light source 40, a holder 50, a housing 60, a frame member 70, and a power supply unit 90.

The light source 40 includes, for example, a substrate 41 and a light-emitting element 42.

In this embodiment, the substrate 41 has a substantially rectangular shape. Specifically, in this embodiment, the substrate 41 has a substantially rectangular shape that is long in the third direction D3. That is, the substrate 41 extends in the third direction D3. In addition, in this embodiment, the substrate 41 has a substantially flat plate shape. Wiring for supplying power to the light-emitting element 42 is formed on the substrate 41.

The light-emitting element 42 emits light. The light-emitting element 42 is, for example, a light-emitting diode (LED). There may be one or more light-emitting elements 42. In this embodiment, the light source 40 includes multiple light-emitting elements 42. Alternatively, the light-emitting element 42 may include an organic EL (Electro-Luminescence) element or a laser diode. The light-emitting element 42 is disposed on the substrate 41. Specifically, the light-emitting element 42 is attached to the mounting surface of the substrate 41. That is, the light-emitting element 42 is mounted on the substrate 41.

In this embodiment, the multiple light-emitting elements 42 are arranged in a row along the third direction D3. However, the arrangement of the multiple light-emitting elements 42 is not limited to a single row. The multiple light-emitting elements 42 may be arranged in two or more rows along the third direction D3, or may be arranged in a staggered pattern.

The light source 40 may have a COB (chip on board) structure in which a plurality of light emitting elements 42 are mounted on the mounting surface of the substrate 41 and sealed with phosphor. Alternatively, the light source 40 may have an SMD (surface mount device) structure in which a unit in which the light emitting elements 42 and phosphor are integrated is mounted on the mounting surface of the substrate 41 and electrically connected to the conductor of the substrate 41. Alternatively, the light source 40 may be composed of so-called bullet-shaped light emitting elements 42. When the light source 40 is composed of bullet-shaped light emitting elements 42, the light source 40 may or may not include the substrate 41.

In this embodiment, the cover 30 has a generally rectangular prism shape that is elongated in the third direction D3. Specifically, the cover 30 has, for example, a generally hexagonal prism shape. The cover 30 has, for example, both ends in the third direction D3 that are open.

The cover 30 covers the light source 40. Specifically, the cover 30 covers the light source 40 so that the inner surface of the cover 30 faces the light-emitting surface 42a of the light-emitting element 42. The cover 30 is, for example, a shade or a diffusion cover. The cover 30 is transparent or translucent, and passes the light emitted by the light-emitting element 42. In order to reduce the glare felt by the user due to the light passing through the cover 30, it is preferable that the cover 30 is, for example, milky white or translucent, and diffuses the light passing through the cover 30. In this case, the cover 30 is made of, for example, a milky white or translucent material. In this embodiment, the cover 30 is a diffusion cover that diffuses the light emitted by the light-emitting element 42. Therefore, the graininess of the light emitted by each of the multiple light-emitting elements 42 can be suppressed. Note that the "graininess" refers to a state in which the light from the light-emitting element 42 reaches multiple points of the cover 30 locally, and the outer surface of the cover 30 emits strong light at multiple points. For example, if the light source 40 is a point light source, the portion of the cover 30 located within the illumination range of the light-emitting element 42 is illuminated more strongly than other portions of the cover 30, but by using a diffusion cover for the cover 30, the light from the light-emitting element 42 can be prevented from appearing in a granular (dot-like) pattern (grainy appearance) on the outer surface of the cover 30.

The cover 30 is made of, for example, resin. When the cover 30 is a diffusion cover that diffuses the light emitted by the light-emitting element 42, the cover 30 may be formed, for example, by molding a resin containing a light-diffusing material. Alternatively, the cover 30 may be formed by performing a light-diffusing treatment on the surface of a resin molded product molded from a transparent resin. Here, the light-diffusing treatment includes, for example, a fine unevenness forming treatment and a translucent white paint treatment. The fine unevenness forming treatment is a treatment for forming fine unevenness on the surface of the resin molded product. The translucent white paint treatment is a treatment for painting a milky white paint having translucency on the surface of the resin molded product.

The lighting device 1 further includes a pair of cap members 31. The cap members 31 are, for example, end caps. The pair of cap members 31 are attached to both open ends of the cover 30 in the third direction D3, respectively, and close both ends of the cover 30. The cap members 31 are, for example, made of synthetic resin. The cap members 31 may, for example, have a light-blocking property, or may transmit light emitted by the light-emitting element 42. The cap members 31 may also, for example, diffuse light emitted by the light-emitting element 42. Furthermore, the material of the cap members 31 may be the same as or different from the material of the cover 30.

The light distribution member 5 determines the light distribution of the light emitted by the light-emitting element 42. Specifically, the light distribution member 5 determines the light distribution of the light emitted by the light-emitting element 42 by transmitting or reflecting the light emitted by the light-emitting element 42. As a result, the light distribution area of the lighting fixture 1 is determined by the light distribution member 5. The light distribution member 5 includes a transmitting portion 10 and a reflecting portion 20.

In this embodiment, the transmitting portion 10 has a substantially flat plate shape. In addition, in this embodiment, the transmitting portion 10 has a substantially rectangular shape. Specifically, the transmitting portion 10 has a substantially rectangular shape that is long in the third direction D3. The transmitting portion 10 faces the light-emitting element 42 through the cover 30. Specifically, the transmitting portion 10 faces the light-emitting element 42 in the first direction D1 through the cover 30. That is, in the first direction D1, the transmitting portion 10 is located on the opposite side of the cover 30 from the light source 40. The first direction D1 is, for example, perpendicular to the light-emitting surface 42a of the light-emitting element 42. Also, the first direction D1 may be, for example, along a direction from the side where the light-emitting element 42 is arranged toward the room facing the mounting surface Wa. Furthermore, the first direction D1 may be, for example, perpendicular to the mounting surface Wa.

The transmitting section 10 transmits a portion of the light that has passed through the cover 30. Specifically, the transmitting section 10 transmits a portion of the light emitted by the light-emitting element 42 that has passed through the cover 30 and entered the transmitting section 10. More specifically, the transmitting section 10 transmits a portion of the light emitted by the light-emitting element 42 that has passed through the facing section 33 of the cover 30 and entered the transmitting section 10. The facing section 33 will be described later with reference to FIG. 3. Hereinafter, the light emitted by the light-emitting element 42 and entered the transmitting section 10 may be referred to as "light LT1" (see FIG. 3).

In this embodiment, the reflective section 20 has a generally flat plate shape. In this embodiment, the reflective section 20 has a generally rectangular shape. Specifically, the reflective section 20 has a generally rectangular shape that is long in the third direction D3. The reflective section 20 is adjacent to the transmissive section 10. In other words, the reflective section 20 is located on the opposite side of the cover 30 from the light source 40, at a position different from the position of the transmissive section 10.

The reflecting unit 20 reflects a portion of the light that has passed through the cover 30 toward the mounting surface Wa. Specifically, the reflecting unit 20 reflects, among the light emitted by the light-emitting element 42, the light that has passed through the cover 30 and entered the reflecting unit 20 toward the mounting surface Wa. More specifically, the reflecting unit 20 reflects, among the light emitted by the light-emitting element 42, the light that has passed through the inclined portion 32 of the cover 30 and entered the reflecting unit 20 toward the mounting surface Wa. The inclined portion 32 will be described later with reference to FIG. 3. Hereinafter, the light that enters the reflecting unit 20 may be referred to as "light LT2" (see FIG. 3).

According to this embodiment, a portion of the light that passes through the cover 30 is transmitted by the transmitting portion 10, and a portion of the light that passes through the cover 30 is reflected by the reflecting portion 20 toward the mounting surface Wa. Therefore, compared to a lighting fixture that does not have a reflecting portion, the brightness of the mounting surface Wa can be increased while the brightness of the lighting fixture 1 is reduced. As a result, the difference between the brightness of the lighting fixture 1 and the brightness of the mounting surface Wa to which the lighting fixture 1 is attached can be reduced. Furthermore, when a user is present in a room facing the mounting surface Wa, the glare of the lighting fixture 1 felt by the user can be reduced.

In this embodiment, the light distribution member 5 includes two reflective sections 20. Hereinafter, the reflective section 20 located on the side facing the Y direction from the transmissive section 10 in FIG. 1 may be referred to as reflective section 20a, and the reflective section 20 located on the side facing the opposite direction to the Y direction from the transmissive section 10 in FIG. 1 may be referred to as reflective section 20b. The configurations of the reflective sections 20a and 20b are similar, so descriptions of overlapping parts will be omitted as appropriate.

In this embodiment, for example, the sum of the areas of the reflective section 20a and the reflective section 20b is greater than the area of the transmissive section 10. However, the ratio between the area of the transmissive section 10 and the area of the reflective section 20 is not particularly limited.

In this embodiment, the transmissive portion 10 and the reflective portion 20 are integrally molded. That is, in this embodiment, the transmissive portion 10 and the reflective portion 20 are connected to each other. The light distribution member 5 is a metal member such as aluminum, and has a plurality of through holes for passing light. That is, for example, the light distribution member 5 including the transmissive portion 10 and the reflective portion 20 is formed by bending a metal plate having a plurality of through holes. However, as long as the reflective portion 20 is adjacent to the transmissive portion 10, the transmissive portion 10 and the reflective portion 20 may be separate members. In this case, the transmissive portion 10 and the reflective portion 20 may be connected, or a gap may be formed between the transmissive portion 10 and the reflective portion 20.

In order for the reflecting portion 20 to efficiently reflect the light emitted from the light emitting element 42, it is preferable that at least the surface of the light distribution member 5 facing the cover 30 is reflectively treated. The reflective treatment includes, for example, white painting or silver painting. Alternatively, the color of the light distribution member 5 may be a color with high light reflectance, such as white or silver. Furthermore, when the light distribution member 5 is formed from sheet metal, it is preferable that the sheet metal is formed from a material with a color with high reflectance. However, the color and material of the light distribution member 5 are not limited. For example, the light distribution member 5 may have a transparent color (colored transparent or colorless transparent). Furthermore, for example, the light distribution member 5 may be made of resin.

In this embodiment, the holding unit 50 has a generally rectangular parallelepiped shape that is long in the third direction D3. In addition, the holding unit 50 is open at both ends in the third direction D3, for example. The holding unit 50 is, for example, a resin molded product made of a transparent resin. The holding unit 50 may, for example, diffuse light, or may transmit light without diffusing it. In addition, the shape of the holding unit 50 is not particularly limited.

The lighting device 1 further includes a pair of cap members 55. The cap members 55 are, for example, end caps. The pair of cap members 55 are attached to both open ends of the holding portion 50 in the third direction D3, respectively, and close both ends of the holding portion 50. In this embodiment, the material of the cap members 55 is the same as the material of the holding portion 50. However, the material of the cap members 55 may be different from the material of the holding portion 50.

In this embodiment, the inside of the holding unit 50 is hollow. For example, the cover 30 and the reflective unit 20 are arranged in the inner space of the holding unit 50 to which the pair of cap members 55 are attached. That is, the holding unit 50 holds the cover 30 and the reflective unit 20. In this embodiment, since the reflective unit 20 and the transmissive unit 10 are integrally molded, the holding unit 50 holds the cover 30 and the light distribution member 5. That is, the holding unit 50 holds the cover 30, the transmissive unit 10, and the reflective unit 20. The cover 30 arranged in the inner space of the holding unit 50 and the transmissive unit 10 abut, for example. That is, the cover 30 arranged in the inner space of the holding unit 50 and the light distribution member 5 abut, for example. However, the cover 30 arranged in the inner space of the holding unit 50 and the transmissive unit 10 do not have to abut.

The cover 30 and the light distribution member 5 are held in the holding part 50 in a state in which they can abut against the inner surface of the holding part 50. In other words, the cover 30 and the light distribution member 5 are held so as to prevent the cover 30 and the light distribution member 5 from rattling in the inner space of the holding part 50. Therefore, the relative positions of the cover 30 and the light distribution member 5 are fixed. Furthermore, when the holding part 50 is attached to the housing 60, the relative positions of the cover 30, the light distribution member 5, and the light emitting element 42 are fixed.

Therefore, the cover 30 and the reflecting part 20 are held by the holding part 50 without attaching the cover 30 and the reflecting part 20 to the holding part 50. That is, in this embodiment, the holding part 50 can hold the cover 30 and the reflecting part 20 without adhering or fixing the cover 30 and the reflecting part 20 to the holding part 50. As a result, the burden on the worker who assembles the lighting device 1 can be reduced. In addition, the cover 30 and the reflecting part 20 can be held by the holding part 50 without using an adhesive means (e.g., adhesive) for adhering the cover 30 and the reflecting part 20 to the holding part 50 or a fixing means (e.g., screws) for fixing the cover 30 and the reflecting part 20 to the holding part 50. Therefore, there is no optical effect such as a shadow or a change in light distribution due to the light emitted from the cover 30 being blocked by the adhesive means or fixing means.

Here, a method of inserting the cover 30 and the light distribution member 5 into the holding unit 50 will be described. For example, the cover 30 and the light distribution member 5 with the cap member 31 attached are inserted into the inner space of the holding unit 50 from at least one of the open ends in the third direction D3 of the holding unit 50, and the cover 30 and the light distribution member 5 are slid in the inner space of the holding unit 50 in the third direction D3. As a result, the cover 30 and the light distribution member 5 are accommodated in the inner space of the holding unit 50, and the cover 30 and the light distribution member 5 are held by the holding unit 50. In addition, when the reflective unit 20 and the transmissive unit 10 are separate members, the cover 30, the transmissive unit 10, and the reflective unit 20 are each inserted into the inner space of the holding unit 50 from at least one of the open ends in the third direction D3 of the holding unit 50, and the cover 30, the transmissive unit 10, and the reflective unit 20 are each slid in the inner space of the holding unit 50 in the third direction D3. As a result, the cover 30, the transmission section 10, and the reflection section 20 are housed in the inner space of the holding section 50, and the cover 30, the transmission section 10, and the reflection section 20 are held by the holding section 50. Then, the cap member 55 is attached to the holding section 50.

The housing 60 has, for example, a generally rectangular parallelepiped shape that is long in the third direction D3. In addition, the housing 60 has, for example, both ends in the third direction D3 that are open. The housing 60 is located on the opposite side of the light source 40 from the cover 30 in the first direction D1. In this embodiment, the housing 60 is attached to the mounting surface Wa (see FIG. 3).

The lighting fixture 1 further includes a pair of cap members 65. The cap members 65 are, for example, end caps. The pair of cap members 65 are attached to both open ends of the housing 60 in the third direction D3, respectively, and close both ends of the housing 60. In this embodiment, the material of the cap members 65 is the same as the material of the housing 60. However, the material of the cap members 65 may be different from the material of the housing 60. For example, the material of the housing 60 is preferably a metal such as aluminum. In this case, heat dissipation can be improved. Also, for example, the material of the cap members 65 is preferably a resin. In this case, wiring work can be facilitated when connecting and constructing multiple lighting fixtures 1.

In this embodiment, the inside of the housing 60 is hollow. For example, a power supply unit 90 is disposed in the inner space of the housing 60 to which the pair of cap members 65 are attached.

The power supply device 90 supplies power to the light source 40. As a result, the light source 40 emits light using the power supplied from the power supply device 90. The power supply device 90 includes a power supply circuit unit. The power supply circuit unit includes, for example, a power supply circuit and a lighting circuit. The power supply circuit converts the AC power supply voltage from a commercial power source into a DC power supply voltage and supplies the DC power supply voltage to the lighting circuit. The lighting circuit then supplies the DC power supply voltage to the light source 40. The power supply circuit unit may include a controller such as a microcomputer. The microcomputer controls, for example, the lighting circuit.

In addition, for example, a frame member 70 is disposed in the inner space of the housing 60. The frame member 70 is a plate-shaped member and has a substantially rectangular shape that is long in the third direction D3. The light source 40 is attached to the frame member 70. Specifically, the light source 40 is attached to the lower surface of the frame member 70. More specifically, the light source 40 is attached to the frame member 70 so that the light-emitting element 42 faces the inner surface of the cover 30. The light source 40 may be adhered to the frame member 70 by, for example, an adhesive, or may be fixed to the frame member 70 by a fastening member such as a screw. The frame member 70 may be a member made of a metal such as aluminum. In this embodiment, the frame member 70 is made of a metal and functions as a heat sink for the light source 40.

Furthermore, for example, a holding section 50 and a power supply unit 90 are attached to the frame member 70. Specifically, the power supply unit 90 is fixed to the upper surface of the frame member 70. The engagement between the holding section 50 and the frame member 70 will be described later with reference to FIG. 3.

Next, the light distribution member 5 and the cover 30 will be described in detail with continued reference to FIG. 2 and further with reference to FIG. 3. FIG. 3 is a cross-sectional view of the lighting fixture 1 taken along line III-III in FIG. 1. To simplify the drawing, hatching showing the cross section of the mounting surface Wa has been omitted in FIG. 3.

In this embodiment, the transmissive portion 10 is, for example, approximately parallel to the substrate 41. Specifically, in a cross-sectional view, the transmissive portion 10 and the substrate 41 are each approximately parallel to the second direction D2. Therefore, compared to when the transmissive portion is not parallel to the substrate, the amount of light LT1 that passes through the transmissive portion 10 is greater, and brightness can be increased.

In this embodiment, the reflective portion 20 is inclined relative to the transmissive portion 10 and forms an obtuse angle with respect to the transmissive portion 10. In other words, the transmissive portion 10 and the reflective portion 20 are arranged so that the angle θ is an obtuse angle. The angle θ is the angle formed by the transmissive portion 10 and the reflective portion 20. Therefore, the reflective portion 20 reflects the light LT2 that has passed through the cover 30 toward the mounting surface Wa. As a result, the difference between the brightness of the transmissive portion 10 and the brightness of the mounting surface Wa can be made smaller.

The light distribution of the light emitted by the light-emitting element 42 can be changed by changing the configuration of the light distribution member 5. Specifically, for example, the brightness of the lighting fixture 1 and the brightness of the mounting surface Wa can be changed by changing the angle θ of the reflective portion 20 relative to the transmissive portion 10, or by changing at least one of the area of the reflective portion 20 and the area of the transmissive portion 10. In other words, by changing the configuration of the light distribution member 5 according to the user's needs, it is possible to increase the brightness of the lighting fixture 1, decrease the brightness of the lighting fixture 1, increase the brightness of the mounting surface Wa, or decrease the brightness of the mounting surface Wa.

The two reflective sections 20 each extend from both ends 13 of the transmissive section 10 in the second direction D2. Specifically, the reflective section 20a extends from one end 13a of both ends 13 of the transmissive section 10. That is, in a cross-sectional view of the lighting device 1 seen from the third direction D3 (see FIG. 2), one end 13a of the transmissive section 10 is adjacent to one end 23a of the reflective section 20a. The reflective section 20b extends from the other end 13b of both ends 13 of the transmissive section 10. That is, in a cross-sectional view of the lighting device 1 seen from the third direction D3, the other end 13b of the transmissive section 10 is adjacent to one end 23b of the reflective section 20b. Here, both ends 13 of the transmissive section 10 extend along the third direction D3. That is, each of the one end 13a and the other end 13b extends along the third direction D3. In other words, one end 13a and the other end 13b each correspond to the edge of the transmission section 10.

On the other hand, in this embodiment, the other end 24a opposite to the one end 23a of the reflecting portion 20a and the other end 24b opposite to the one end 23b of the reflecting portion 20b are in contact with, for example, the inner surface 50n of the holding portion 50. Therefore, the holding portion 50 can hold the light distribution member 5 including the reflecting portion 20a and the reflecting portion 20b in a state in which it is difficult to displace. Note that at least one of the other end 24a of the reflecting portion 20a and the other end 24b of the reflecting portion 20b does not have to be in contact with the inner surface 50n of the holding portion 50. Here, each of the one end 23a and the other end 24a of the reflecting portion 20a extends along the third direction D3. That is, each of the one end 23a and the other end 24a corresponds to the edge of the reflecting portion 20a. Also, each of the one end 23b and the other end 24b of the reflecting portion 20b extends along the third direction D3. In other words, one end 23b and the other end 24b each correspond to an edge of the reflecting portion 20b.

In the first direction D1, one end 23a of the reflecting portion 20a is located closer to the light source 40 than the other end 24a of the reflecting portion 20a. Therefore, the reflecting portion 20a reflects the light LT2 emitted by the light emitting element 42 to the side away from the light source 40 in the second direction D2. Therefore, an area of the mounting surface Wa different from the embedding hole in which the lighting device 1 is embedded is illuminated. As a result, the mounting surface Wa becomes brighter, and the difference between the brightness of the mounting surface Wa and the brightness of the lighting device 1 can be reduced.

In this embodiment, when the lighting device 1 is assembled, the cover 30 abuts, for example, against the light distribution member 5 and the frame member 70. The cover 30 includes an inclined portion 32 and an opposing portion 33.

In this embodiment, the inclined portion 32 faces the reflecting portion 20 in the first direction D1. The inclined portion 32 is inclined away from the reflecting portion 20 with respect to the transmitting portion 10. Therefore, most of the components of the light LT2 reflected by the reflecting portion 20 reach the mounting surface Wa without being blocked by the cover 30. As a result, the brightness of the mounting surface Wa can be prevented from decreasing.

Specifically, of both ends 34 of the inclined portion 32, one end 34a is connected to the opposing portion 33. The other end 34b opposite to the one end 34a abuts, for example, against the inner surface 50n of the holding portion 50. Note that the other end 34b does not have to abut against the inner surface 50n. In the first direction D1, the other end 34b is located closer to the light source 40 than the one end 34a. Here, both ends 34 extend along the third direction D3. In other words, both ends 34 correspond to the edges of the inclined portion 32.

In this embodiment, for example, the inclined portion 32 diffuses the light passing through the inclined portion 32. Therefore, when a user is present in a room facing the mounting surface Wa, even if the inclined portion 32 is within the user's field of vision, the glare felt by the user can be reduced. In addition, the graininess of the light from the inclined portion 32 can be suppressed.

In addition, in this embodiment, the multiple light-emitting elements 42 are arranged in a row along the third direction D3 at the center of the substrate 41. In this case, the distance between the light-emitting elements 42 and the inclined portion 32 is greater than when the multiple light-emitting elements 42 are arranged in two or more rows along the third direction D3. Therefore, the difference in the amount of light incident on the inclined portion 32 per unit area is smaller across the entire inclined portion 32. As a result, the brightness unevenness of the inclined portion 32 can be reduced.

The facing portion 33 faces the light source 40 (specifically, the light-emitting surface 42a of the light-emitting element 42). Specifically, the facing portion 33 faces the light source 40 (specifically, the light-emitting surface 42a of the light-emitting element 42) in the first direction D1. In a cross-sectional view, the light-emitting surface 42a of the light-emitting element 42 is, for example, approximately parallel to the second direction D2. In this embodiment, the facing portion 33 is approximately parallel to the light-emitting surface 42a of the light-emitting element 42. Therefore, the brightness of the light LT1 that passes through the cover 30 and enters the transmission portion 10 can be increased compared to when the facing portion 33 is not parallel to the light-emitting surface 42a of the light-emitting element 42.

The facing portion 33 faces the transmissive portion 10. Specifically, the facing portion 33 faces the transmissive portion 10 in the first direction D1. In this embodiment, the facing portion 33 is approximately parallel to the transmissive portion 10. That is, in this embodiment, the facing portion 33 is approximately parallel to the substrate 41 in a cross-sectional view. Therefore, the brightness of the light LT1 that passes through the cover 30 and enters the transmissive portion 10 can be further increased compared to when the facing portion 33 is not parallel to the substrate 41.

The housing 60 has a generally U-shape in side view. Specifically, the housing 60 has a generally U-shape with sharp corners in side view. In this embodiment, the housing 60 includes a base portion 61, a pair of wall portions 62, and a pair of flange portions 63.

In this embodiment, the base portion 61 is substantially parallel to the substrate 41. Each of the pair of walls 62 extends from the base portion 61 along the first direction D1. That is, each of the pair of walls 62 faces the second direction D2.

The pair of flanges 63 extend outward from the tips of the pair of wall portions 62 in the second direction D2. For example, the lighting fixture 1 is attached to the mounting surface Wa by sandwiching the mounting surface Wa between the mounting spring (not shown) and the flange 63 provided in the lighting fixture 1. That is, the flange 63 supports the mounting surface Wa. When the lighting fixture 1 is embedded in the mounting surface Wa, the mounting spring is located, for example, on the opposite side of the light distribution member 5 with respect to the mounting surface Wa. Note that, when the lighting fixture 1 is embedded in the mounting surface Wa as in this embodiment, the lighting fixture 1 may be attached to the mounting surface Wa by, for example, fixing the base portion 61 to a fixing member (for example, a hanging bolt) installed in the building. In this case, the lighting fixture 1 may or may not include a mounting spring. That is, in this case, the mounting spring can be omitted. Also, when the lighting fixture 1 is embedded in the mounting surface Wa as in this embodiment, the housing 60 includes a pair of flanges 63. However, if the lighting fixture 1 is directly attached to the mounting surface Wa or suspended from the mounting surface Wa, the housing 60 may or may not include the pair of flanges 63. In other words, in this case, the pair of flanges 63 can be omitted.

The lighting fixture 1 further includes a mounting bracket 80. The mounting bracket 80 has a main body portion 81 and a pair of elastic portions 82.

The main body 81 engages, for example, with the frame member 70. When the main body 81 engages with the frame member 70, the mounting bracket 80 is fixed to the frame member 70.

The elastic portion 82 extends from both ends of the main body portion 81 in the second direction D2 in the first direction D1 so as to move away from the light source 40. The elastic portion 82 is curved and has elasticity toward the outside in the second direction D2. Therefore, a biasing force acts from the elastic portion 82 toward the housing 60. As a result, the holding portion 50 is attached to the housing 60 via the frame member 70 fixed to the mounting bracket 80. For example, the holding portion 50 can be attached to the housing 60 by pressing the holding portion 50 attached to the mounting bracket 80 in the first direction D1 so as to approach the housing 60. On the other hand, the holding portion 50 can be removed from the housing 60 by pulling the holding portion 50 in the first direction D1 so as to move away from the housing 60. In other words, the holding portion 50 is detachable from the housing 60. Specifically, the holding portion 50, the frame member 70, and the mounting bracket 80 can be removed from the housing 60 by pulling the holding portion 50 in the first direction D1 so as to move away from the housing 60.

The frame member 70 has a pair of engaged portions 71. In a cross-sectional view, the pair of engaged portions 71 are, for example, recesses formed on both ends of the frame member 70 in the second direction D2.

The holding portion 50 includes, for example, an engaging portion 51. The engaging portion 51 is located at the tip portion of the side surface of the holding portion 50. The engaging portion 51 engages with the engaged portion 71. Thus, the holding portion 50 is attached to the frame member 70. As a result, the light distribution member 5 and the cover 30 can be accommodated in the space formed by the frame member 70 and the holding portion 50 without attaching the cover 30 and the light distribution member 5 to the holding portion 50.

Here, in this embodiment, the frame member 70 abuts against the cover 30 in, for example, the first direction D1. That is, the cover 30 is held by the holding portion 50 without being attached to the frame member 70.

Next, the light distribution member 5 will be described in detail with reference to Figs. 4 and 5. Fig. 4 is a perspective view showing the light distribution member 5. In detail, Fig. 4 shows the light distribution member 5 as viewed from diagonally below. Fig. 5 shows a plan view of the light distribution member 5 as viewed from above.

The transmissive section 10 has a first reflective region 11 and a first transmissive region 12. In this embodiment, the transmissive section 10 has a plurality of first transmissive regions 12. In this embodiment, the first transmissive region 12 has an approximately perfect circular shape. In this embodiment, the plurality of first transmissive regions 12 are arranged in a triangular lattice pattern. The first transmissive region 12 transmits light. The first reflective region 11 reflects light. Therefore, a portion of the light LT1 (see FIG. 3) incident on the transmissive section 10 is transmitted, and a portion of the light LT1 incident on the transmissive section 10 is reflected toward the cover 30. As a result, the light passing through the transmissive section 10 can be prevented from becoming too large. That is, the brightness of the transmissive section 10 can be prevented from becoming too large. Specifically, the brightness of the surface of the transmissive section 10 opposite the surface facing the cover 30 can be prevented from becoming too large.

The arrangement of the multiple first transmission regions 12 is not particularly limited. For example, the multiple first transmission regions 12 may be arranged in a square lattice or a rectangular lattice. The first transmission regions 12 may be arranged at equal intervals or at unequal intervals in the transmission section 10. The size of the multiple first transmission regions 12 may be uniform or non-uniform. The number of first transmission regions 12 per unit area of the transmission section 10 may be uniform or non-uniform for each part of the transmission section 10. In this case, the size per unit area of the light passing through the transmission section 10 can be made uniform or non-uniform. For example, if the center of the transmission section 10 in the second direction D2 is closer to the light emitting element 42 than the outer side of the transmission section 10 in the second direction D2, the light incident on the center of the transmission section 10 in the second direction D2 may be larger than the light incident on the outer side of the transmission section 10 in the second direction D2. Therefore, by making the number of first transmission regions 12 per unit area near the center in the second direction D2 of the transmission section 10 smaller than the number of first transmission regions 12 per unit area near the outside in the second direction D2 of the transmission section 10, it is possible to reduce non-uniformity in the amount of light passing through the transmission section 10 throughout the entire transmission section 10. In other words, it is possible to reduce uneven illumination on the surface of the transmission section 10 opposite the surface facing the cover 30.

The reflecting section 20 has a second reflective region 21 and a second transmissive region 22. In this embodiment, the reflecting section 20 has a plurality of second transmissive regions 22. In this embodiment, the second transmissive region 22 has a substantially circular shape. In this embodiment, the size of the second transmissive region 22 is substantially the same as the size of the first transmissive region 12. In this embodiment, the plurality of second transmissive regions 22 are arranged in a triangular lattice pattern. The second transmissive region 22 transmits light. The second reflective region 21 reflects light. Therefore, a portion of the light LT2 (see FIG. 3) incident on the reflecting section 20 is reflected toward the mounting surface Wa, and a portion of the light LT2 incident on the reflecting section 20 is transmitted.

The size of the second transmission region 22 may be different from the size of the first transmission region 12. The arrangement of the multiple second transmission regions 22 is not particularly limited. For example, the multiple second transmission regions 22 may be arranged in a square lattice or a rectangular lattice. Furthermore, the second transmission regions 22 may be arranged at equal intervals or at unequal intervals in the reflecting section 20. Furthermore, the size of the multiple second transmission regions 22 may be uniform or non-uniform. Furthermore, the number of second transmission regions 22 per unit area of the reflecting section 20 may be uniform or non-uniform for each part of the reflecting section 20. In this case, the size per unit area of the light reflected by the reflecting section 20 can be made uniform or non-uniform. For example, if the distance between the light emitting element 42 and the reflecting portion 20b is shorter at a location closer to the one end 23b and the distance between the light emitting element 42 and the reflecting portion 20b is longer at a location closer to the other end 24b, the light incident on the reflecting portion 20b may be larger at a location closer to the one end 23b and smaller at a location closer to the other end 24b. Therefore, by increasing the number of second transmission regions 22 per unit area at a location closer to the one end 23b and decreasing the number of second transmission regions 22 per unit area at a location closer to the other end 24b, the amount of light reflected by the reflecting portion 20b can be reduced from being non-uniform throughout the entire reflecting portion 20b. The reflecting portion 20a is also similar to the reflecting portion 20b.

Specifically, in this embodiment, the first transmissive region 12 is formed by a through hole. Also, in this embodiment, the second transmissive region 22 is formed by a through hole. Therefore, the transmissive portion 10 and the reflective portion 20 can be formed of the same material. The same material is, for example, a metal plate with a through hole formed therein. As a result, the transmissive portion 10 and the reflective portion 20 can be easily manufactured. Also, when the transmissive portion 10 and the reflective portion 20 are integrally molded products, the transmissive portion 10 and the reflective portion 20 can be manufactured simply by bending the metal plate with a through hole formed therein. Furthermore, light distribution members 5 with different configurations can be easily manufactured simply by changing at least one of the angle at which the metal plate is bent and the position at which the metal plate is bent.

As shown in FIG. 5, when the light distribution member 5 is viewed from the first direction D1, the first transmission region 12 of the transmission portion 10 has an approximately perfect circular shape, while the second transmission region 22 of the reflection portion 20, which is inclined relative to the transmission portion 10, has an approximately elliptical shape. In a plan view when the light distribution member 5 is viewed from the first direction D1, the size of the second transmission region 22 is approximately the same as the size of the actual second transmission region 22 along the third direction D3, and is smaller along the second direction D2. That is, in a plan view when the light distribution member 5 is viewed from the first direction D1, the second transmission region 22 is smaller than the actual second transmission region 22. Therefore, the brightness of the light LT2 transmitted through the second transmission region 22 is reduced compared to when the reflection portion 20 is not inclined relative to the transmission portion 10 so as to form an obtuse angle with respect to the transmission portion 10. As a result, the brightness of the light LT2 reflected toward the mounting surface Wa is increased, and the difference between the brightness of the mounting surface Wa and the brightness of the lighting device 1 can be reduced.

(First Modification)
Next, a lighting fixture 1x according to a first modified example of the present embodiment will be described with reference to Fig. 6. The first modified example differs from the present embodiment in that the shape of the light distribution member 5x is different from the shape of the light distribution member 5x according to the present embodiment. Below, the differences between the first modified example and the present embodiment will be mainly described.

Figure 6 is a cross-sectional view of a lighting device 1x according to a first modified example of this embodiment. As shown in Figure 6, in this modified example, the light distribution member 5x includes a transmissive portion 10x and two reflective portions 20x. The transmissive portion 10x is adjacent to the two reflective portions 20x. In this modified example, the transmissive portion 10x is connected to each of the two reflective portions 20x.

In this modified example, the transmissive portion 10x has a substantially V-shape in cross section. The transmissive portion 10x includes two main surfaces 10xs extending in the third direction D3 (see FIG. 1). The inclination of the main surface 10xs with respect to the second direction D2 is substantially the same as the inclination of the reflective portion 20x adjacent to the main surface 10xs with respect to the second direction D2.

The transmissive portion 10x faces the opposing portion 33 in the first direction D1. In this modified example, the transmissive portion 10x abuts the opposing portion 33. However, the transmissive portion 10x does not have to abut the opposing portion 33. In addition, the reflective portion 20x faces the inclined portion 32 in the first direction D1.

In this modified example, the transmitting portion 10x transmits light that has passed through the cover 30. Specifically, the transmitting portion 10x transmits light that has passed through, for example, the opposing portion 33 of the cover 30. In addition, the reflecting portion 20x reflects the light that has passed through the cover 30 toward the mounting surface Wa. Specifically, the reflecting portion 20x reflects, for example, the light that has passed through the inclined portion 32 of the cover 30 toward the mounting surface Wa. Therefore, the brightness of the mounting surface Wa can be increased. As a result, the difference between the brightness of the lighting device 1 and the brightness of the mounting surface Wa can be reduced.

Here, for example, the size and shape of the cover 30 in this modified example are the same as the size and shape of the cover 30 shown in FIG. 3. Therefore, in a cross-sectional view, the inclination of the reflecting portion 20x relative to the second direction D2 is gentler than the inclination of the reflecting portion 20 relative to the second direction D2 shown in FIG. 3.

(Second Modification)
Next, a lighting fixture 1y according to a second modified example of the present embodiment will be described with reference to Fig. 7. The second modified example differs from the present embodiment in that the shape of the light distribution member 5y is different from the shape of the light distribution member 5 according to the present embodiment, and the shape of the cover 30y is different from the shape of the cover 30 according to the present embodiment. Below, the differences between the second modified example and the present embodiment will be mainly described.

Figure 7 is a cross-sectional view of a lighting device 1y according to a second modified example of this embodiment. As shown in Figure 7, in this modified example, the light distribution member 5y includes a transmissive portion 10y and two reflective portions 20y. The transmissive portion 10y is adjacent to the two reflective portions 20y. In this modified example, the transmissive portion 10y is connected to each of the two reflective portions 20y.

In this modified example, the transmissive portion 10y has a substantially V-shape in cross section. The transmissive portion 10y includes two main surfaces 10ys extending in the third direction D3 (see FIG. 1). The inclination of the main surface 10ys with respect to the second direction D2 is substantially the same as the inclination of the reflective portion 20y adjacent to the main surface 10ys with respect to the second direction D2. In addition, in this modified example, the angle of the reflective portion 20y with respect to the second direction D2 when held by the holding portion 50 is substantially the same as the angle of the reflective portion 20 shown in FIG. 3 with respect to the second direction D2.

In this modified example, the cover 30y includes an inclined portion 32y and an opposing portion 33y. The opposing portion 33y faces the light source 40 (specifically, the light-emitting element 42). Specifically, the opposing portion 33y faces the light source 40 (specifically, the light-emitting element 42) in the first direction D1. The inclined portion 32y is inclined toward the side away from the reflecting portion 20y with respect to the opposing portion 33y.

The transmissive portion 10y faces the opposing portion 33y in the first direction D1. In this modified example, the transmissive portion 10y abuts the opposing portion 33y. However, the transmissive portion 10y does not have to abut the opposing portion 33y. In addition, the reflective portion 20y faces the inclined portion 32y in the first direction D1.

In this modified example, the length Ly from the facing portion 33y of the cover 30y to the light source 40 is shorter than the length from the facing portion 33 of the cover 30 to the light source 40 shown in FIG. 3. Therefore, the brightness of the facing portion 33y is increased. Furthermore, in this modified example, the transmitting portion 10y transmits light that has passed through the cover 30y. Specifically, the transmitting portion 10y transmits, for example, light that has passed through the facing portion 33y of the cover 30y. In addition, the reflecting portion 20y reflects light that has passed through the cover 30 toward the mounting surface Wa. Specifically, the reflecting portion 20y reflects, for example, light that has passed through the inclined portion 32y of the cover 30 toward the mounting surface Wa. Therefore, the difference between the brightness of the lighting device 1y and the brightness of the mounting surface Wa can be reduced while increasing the brightness of the mounting surface Wa and the brightness of the lighting device 1y.

The above describes an embodiment of the present invention with reference to the drawings. However, the present invention is not limited to the above embodiment, and can be implemented in various aspects without departing from the gist of the present invention. In addition, the multiple components disclosed in the above embodiment can be modified as appropriate.

In addition, the drawings mainly show each component in a schematic manner to facilitate understanding of the invention, and the thickness, length, number, spacing, etc. of each component shown in the drawings may differ from the actual ones due to the convenience of creating the drawings. Furthermore, the configuration of each component shown in the above embodiment is one example and is not particularly limited, and it goes without saying that various modifications are possible within a range that does not substantially deviate from the effects of the present invention.

In this embodiment, the lighting device 1 has a substantially rectangular parallelepiped shape. However, as long as the lighting device 1 has a transmissive section 10 and a reflective section 20, the lighting device 1 may have a shape other than a rectangular parallelepiped shape. For example, the lighting device 1 may have a substantially cubic shape, a substantially cylindrical shape, or a substantially polygonal tube shape.

In addition, in this embodiment, the cover 30 has a generally trapezoidal shape in cross section. However, as long as the cover 30 has the inclined portion 32, the cover 30 may have a generally triangular shape, a generally polygonal shape, or a generally semicircular shape.

Furthermore, in this embodiment, a pair of cap members 31 was attached to each of both ends of the cover 30 in the third direction D3. That is, the cover 30 and the cap members 31 were separate members. However, the cover 30 and the pair of cap members 31 may be integrally molded products. Furthermore, a pair of cap members 55 was attached to each of both ends of the holding portion 50 in the third direction D3. That is, the holding portion 50 and the cap members 55 were separate members. However, the holding portion 50 and the pair of cap members 55 may be integrally molded products. Furthermore, a pair of cap members 65 was attached to each of both ends of the housing 60 in the third direction D3. That is, the housing 60 and the cap members 65 were separate members. However, the housing 60 and the pair of cap members 65 may be integrally molded products.

Furthermore, in this embodiment, the first transmission region 12 is configured by a through hole, and the second transmission region 22 is configured by a through hole. However, as long as the first transmission region 12 and the second transmission region 22 transmit light, the first transmission region 12 and the second transmission region 22 do not have to be configured by a through hole. For example, the light distribution member 5 may be made of a transparent resin, and the first transmission region 12 and the second transmission region 22 may be defined by subjecting the regions corresponding to the first reflection region 11 and the second reflection region 21 to a reflective processing. In this case, the first transmission region 12 and the second transmission region 22 are configured by a transparent resin.

Furthermore, in this embodiment, the cover 30 and the light distribution member 5 are separate members, but the cover 30 and the light distribution member 5 may be integrally molded.

Furthermore, in this embodiment, the transmissive section 10 has a first reflective area 11 and a first transmissive area 12. Furthermore, the reflective section 20 has a second reflective area 21 and a second transmissive area 22. However, as long as the transmissive section 10 has the first reflective area 11 and the first transmissive area 12, the reflective section 20 does not have to have the second transmissive area 22.
