Description

The present disclosure relates to a lighting fixture having two light source units.

Conventionally, a first light source unit that emits blue light and a second light source unit that emits white light are installed inside a fixture body that is installed on a part to be mounted such as a ceiling and has an opening toward the illumination space. There are light fixtures. The first light source unit includes a blue LED module that emits blue light and a light guide plate that is provided to cover the opening of the device body. The light emitted from the blue LED module is guided through the light guide plate and is irradiated from the opening side surface of the appliance body toward the opening of the appliance body. The second light source unit includes a white LED module that emits white light and a diffuser plate formed in the shape of a truncated quadrangular pyramid and provided on the opening side of the instrument body. The white LED module is arranged on the back side of the diffuser plate. The light emitted from the white LED module enters the diffuser plate and is irradiated diagonally downward into the opening of the instrument body.
(For example, Patent Document 1)

Japanese Patent Application Publication No. 2021-026796

However, in the lighting fixture described in Patent Document 1, since the light guide plate is exposed from the opening of the fixture body, there is a risk that foreign matter such as dirt and dust may adhere to the light guide plate. When foreign matter adheres to the light irradiation surface of the light guide plate, light may not be uniformly emitted at the portion of the irradiation surface to which the foreign matter has adhered, and the design may deteriorate.

Here, as a method of preventing foreign matter from adhering to the light guide plate, which is not described in Patent Document 1, but is considered, there is a method of providing a transparent cover so as to close the opening of the device body. Since the transparent cover closes the opening of the instrument body, it can prevent foreign matter from entering the instrument body from the outside to the inside, and can prevent foreign matter from adhering to the light guide plate provided inside the instrument body. However, in the lighting fixture described in Patent Document 1, the second light source unit is provided inside the fixture body, and the light emitted from the white LED module enters the diffuser plate and is directed diagonally downward toward the opening of the fixture body. irradiated. In other words, the light that has passed through the diffuser plate is irradiated from the inside of the device body toward the outside and passes through the opening. Therefore, when a transparent cover is provided to cover the opening of the device body, some of the light emitted from the diffuser plate is directed from the outside of the device body to the inside by the surface of the transparent cover that faces the light guide plate. There is a possibility that a new problem will arise in that the light will be reflected on the light guide plate. That is, the design quality may be degraded due to the white light emitted from the white LED being reflected on the irradiation surface of the light guide plate that irradiates blue light.

The present disclosure has been made to solve the above-mentioned problems, and suppresses light emitted from a first light source module, which is a white LED module, from being reflected in a second light-transmitting part, which is a light guide plate. The purpose is to provide lighting equipment with

The lighting device according to the present disclosure includes a device main body having an opening formed on one side, a frame portion provided to protrude in a direction toward the other side of the device main body as it goes inward from the outer edge of the opening, a cover section provided on the other side of the frame section, and a plate-shaped first transparent section provided so as to close the opening of the instrument body; a second light-transmitting part in the form of a plate, a first light source module housed in the fixture body and emitting first light toward the frame part, and a second transparent part housed in the fixture body. a second light source module that emits second light toward the light section, the first light source module is arranged on one side of the cover section, and the second light source module is arranged on the other side of the cover section. will be placed in

As shown in FIGS. 1 and 2, the lighting fixture 1 according to Embodiment 1 is a ceiling-mounted lighting fixture that is installed by being embedded in an opening (not shown) provided in a part to be installed such as a ceiling or wall (not shown). It is a type of lighting equipment. The lighting fixture 1 includes a fixture body 10, a first light source unit 20, and a second light source unit 30. Although the lighting fixture 1 has been described as a ceiling-embedded lighting fixture, it may also be a direct-mounted lighting fixture that is attached to a fastener provided on the ceiling, wall, or the like.

As shown in FIG. 2, the instrument main body 10 is formed in a rectangular box shape, and is open at the bottom. The instrument main body 10 has a main surface portion 11, a side surface portion 12, a flange portion 13, and a V-spring fitting 14. The instrument body 10 houses a first light source unit 20 and a second light source unit 30.

The main surface portion 11 is formed into a rectangular plate shape. Main surface portion bolt holes 111 are formed in the main surface portion 11 . The instrument main body 10 is fixed to the attached part by inserting a hanging bolt provided on the attached part into the main surface bolt hole 111 and fastening with a nut. The main surface portion 11 is formed with a wire insertion hole 112 through which an electric wire and a signal wire (not shown) are inserted.

As shown in FIG. 3, the first light source unit 20 includes a white LED (Light Emitting Diode) module 21, a first transparent section 22, and a packing 23.

As shown in FIG. 5, the first light source module 21 emits white light inward. The first light source module 21 is bonded to the inside of three of the first module holding members 133 using a silicone adhesive or the like. The first light source module 21 includes a white LED substrate 211 and a white LED 212. Although it has been explained that the first light source module 21 is bonded to the first module holding member 133 using silicone adhesive, it may also be attached to the first module holding member 133 using screws, or may be attached to the first module holding member 133 by soldering or the like. It may be welded to the module holding member 133, and any method that can be fixed to the first module holding member 133 may be used.

The white LED substrate 211 is formed in a plate shape, and the outer surface is fixed to the first module holding member 133, and the white LED 212 is mounted on the inner surface.

The white LED 212 is a light-emitting element that emits white light. Note that the white LED 212 is not limited to an LED, and may be a light-emitting element such as a laser or an organic LED.

The first light-transmitting section 22 has a frame section 221 and a cover section 222. The first light-transmitting section 22 is formed in a quadrangular pyramid shape with an open bottom. The first light-transmitting section 22 is arranged so as to cover the opening 131. The first light-transmitting section 22 is formed from a light-transmitting, transparent plastic resin such as acrylic resin or polycarbonate resin. The first light-transmitting section 22 may be formed by integrally molding the frame section 221 and the cover section 222 by injection molding or vacuum molding, or may be formed by molding the frame section 221 and the cover section 222 separately and bonding them together with an adhesive or the like.

The frame portion 221 has four plate-like plates each having a trapezoidal shape in which the length of the upper side is shorter than the length of the lower side. The frame portion 221 is formed by integrating four pieces into a truncated quadrangular pyramid with open upper and lower sides, and its outer end is placed on the outer edge of the opening 131 of the flange portion 13 via the packing 25. Each of the four side surfaces of the frame portion 221 is tapered from the outside to the inside and from the bottom to the top. The frame portion 221 includes a sun frame portion 221A and a shade frame portion 221B. Here, the surface where the two opposing surfaces of the frame portion 221 face each other is called the inner surface, and the surface opposite to the inner surface is called the back surface.

The sun frame part 221A is three of the four frames of the frame part 221, and has a back surface coated with a translucent white paint. The sun frame portion 221A is formed by three adjacent frame portions 221. The first light source module 21 is arranged on the back side of the sun frame part 221A. The sun frame section 221A emits the light emitted from the first light source module 21 diagonally downward toward the opening 131 of the flange section 13. Note that the frame portion 221A is not limited to one whose back surface is coated with a translucent milky white paint, but may be made of a translucent milky white material.

The shade frame section 221B is one of the four frames of the frame section 241, and has a light shielding sheet (not shown) attached to the back surface. The shade frame section 221B blocks the white light emitted from the first light source module 21 provided in pair with the sunny frame section 221A so as not to leak from the back side to the inner side. Note that the shade frame portion 221B is not limited to one having a light-shielding sheet attached to the back surface, but may be coated with a light-shielding paint.

The frame section 221 has a configuration that combines three sunlight frame sections 221A that emit white light and a shade frame section 221B that blocks light incident from the back side. Therefore, the light emitted from the frame portion 221 is emitted from three directions, creating a visual effect with a sense of depth, such as the sunlight shining through the window frame in the sun, or the light shining from outside through the window frame in the shade. be able to. Although it has been explained that the frame portion 221 of this embodiment is composed of three pieces of the sun frame portion 221A and one piece of the shade frame portion 221B, the frame portion 221 is not limited thereto. It may also be configured with two shade frame parts 221B.

As shown in FIG. 5, the packing 23 is installed between the upper surface of the flange portion 13 and the lower surface of the frame portion 221, and prevents the flange portion 13 and the frame portion 221 from coming into direct contact. This prevents damage caused by collisions with each other due to vibrations, etc. Moreover, the packing 23 is installed between the flange part 13 and the frame part 221 to suppress the white light emitted from the white LED 212 from leaking from the gap between the flange part 13 and the frame part 221.

The cover part 222 is formed into a rectangular flat plate and is transparent and has light-transmitting properties. The cover part 222 is provided so as to close the upper opening of the frame part 221. By blocking the opening 131 of the flange portion 13 with the frame portion 221, the cover portion 222 can prevent foreign matter from entering the instrument body from the outside. The cover part 222 is arranged above the first light source module 21 in the vertical direction. Therefore, the cover part 222 is not irradiated with the light emitted from the sun frame part 221A to the opening 131 of the flange part 13.

As shown in FIG. 4, the second light source unit 30 includes a second module holding member 31, a lower guide plate 32, an upper guide plate 33, a second transparent section 34, a packing 35, a reflective sheet 36, a second It includes a light source module 37 and a top plate 38.

The second module holding member 31 is formed in a rectangular frame shape and is attached above the first module holding member 133. The second module holding member 31 has a second module holding part 311 and a second module holding part recess 312 .

The second module holding parts 311 are plate-shaped parts that are provided so as to protrude from the upper surfaces of the opposing sides of the second module holding member 31, respectively.

The second module holding part recess 312 is a groove formed in a concave shape downward on the side of the second module holding member 31 where the second module holding part 311 is provided.

The lower guide plate 32 is composed of two rod-shaped members. The lower guide plate 32 is arranged along the second module holding part 311 and is attached to the upper surface of the second module holding member 31. As shown in FIG. 5, the lower guide plate 32 is provided with a protrusion 321 that protrudes downward at one end in the transverse direction. The protruding portion 321 prevents the second light-transmitting portion 34 from moving in the board width direction by being caught in the second module holding portion recess 312 of the second module holding member 31.

The upper guide plate 33 is composed of two rod-shaped members. The upper guide plate 33 is arranged above the second light-transmitting part 34. The upper guide plate 33 is arranged parallel to the lower guide plate 32.

The second light-transmitting part 34 is a light guide plate formed in a rectangular plate shape, and is disposed between the lower guide plate 32 and the upper guide plate 33 in the vertical direction, as shown in FIG. be. The second light transmitting section 34 transmits the light emitted from the second light source module 37 and emits blue light downward from the lower surface that is the output surface. The second transparent portion 34 has a first end face 341 that is an end face in a direction parallel to the board width direction, and a second end face that is an end face in a direction perpendicular to the direction in which the first end faces 341 face each other in the board width direction. 2 end faces 342. Further, the second light-transmitting portion 34 includes a scatterer therein, which is a particle such as silica that scatters light.

The second light-transmitting portion 34 is preferably formed smoothly and mirror-finished so that the upper surface totally reflects the incident light. If the upper surface of the second light-transmitting portion 34 is scratched, total reflection will be less likely to occur at the scratched area, and a part of the lower surface corresponding to the scratched area may appear to shine white, reducing the design quality. For this reason, a reflective sheet is placed so as to cover the upper surface of the second light-transmitting portion 34, thereby preventing the upper surface of the second light-transmitting portion 34 from being scratched.

Furthermore, since the lower surface of the second light-transmitting portion 34 is a light-emitting surface that emits blue light, if foreign matter adheres to it or it gets scratched, that part becomes a bright spot and appears to glow white, resulting in poor design. There is a risk that it will decrease. The cover portion 222 of the first light-transmitting portion 22 is disposed on the lower side of the second light-transmitting portion 34, thereby suppressing attachment of foreign matter and damage. The light emitted from the lower surface of the second light-transmitting section 34 is transmitted through the cover section 222 of the first light-transmitting section 22 . At this time, the closer the cover part 222 is to the second light-transmitting part 34, the more difficult it is for the light emitted from the second light-transmitting part 34 to be reflected, and it is possible to suppress the reduction in the visual effect imitating the blue sky. desirable for this reason. However, when the cover part 222 comes into contact with the second light-transmitting part 34 , light is likely to be reflected upward by the lower surface of the second light-transmitting part 34 . It is desirable that they be arranged at a distance of 1 mm or more.

As shown in FIG. 5, when the first light source unit 20 and the second light source unit 30 are attached to the instrument main body 10, the packing 35 is attached to the upper side of the cover section 222 of the first transparent section 22. It is arranged between the lower side of the second light-transmitting part 34 and the lower side of the second transparent part 34. The packing 35 closes the space between the cover part 242 and the second light-transmitting part 34 and prevents the white light emitted from the first light source module 21 from leaking to the lower side of the second light-transmitting part 34. suppress. Further, the packing 35 is made of an elastic member, and prevents the cover portion 222 and the second light-transmitting portion 34 from coming into contact with each other and being damaged.

The reflective sheet 36 is disposed above the second light-transmitting section 34 to cover the second light-transmitting section 34, and reflects light transmitted upward from the second light-transmitting section 34 downward. It is. The reflective sheet 36 has a lower reflective surface formed in a finely uneven shape, and an air layer is provided between the reflective sheet 36 and the second transparent section 34 so that the upper surface of the second transparent section 34 is fully covered. It is possible to prevent reflection from occurring.

The second light source module 37 includes a plate-shaped blue LED substrate 371 and a light emitting element 372, and emits blue light inward. The second light source module 37 is disposed between the second transparent part 34 and the side surface part 12 of the instrument main body 10 in the board width direction of the second transparent part 34, and is located inside the second module holding part 311. It is attached to the surface so as to face the first end surface 341 of the second light-transmitting section 34 . The plurality of light emitting elements 372 are, for example, blue LEDs, white LEDs, and green LEDs, and are controlled by a dimmer (not shown) to emit blue light whose color tone can be changed.

The top plate 38 covers the second light-transmitting portion 34 from above and protects the second light-transmitting portion 34 . The top plate 38 has a lighting device 39 placed thereon.

Next, using FIGS. 6 to 8, the path of white light emitted from the first light source unit 20 and the path of blue light emitted from the second light source unit 30 in the lighting fixture 1 according to Embodiment 1 will be explained. I will explain about it. FIG. 6 is a schematic diagram of the lighting fixture 1 showing a path of white light emitted from the first light source unit 20 and a path of blue light emitted from the second light source unit 30. FIG. 7 is a diagram showing a comparative example, in which the first light source module 21 is arranged above the cover part 222a, and the cover part 222a is arranged above the frame part 221. FIG. 2 is a schematic diagram of a lighting fixture showing a path of emitted white light. FIG. 8 is a diagram showing a comparative example, in which the first light source module 21 is arranged above the cover part 222b, and the cover part 222b is arranged below the frame part 221. FIG. 2 is a schematic diagram of a lighting fixture showing a path of white light emitted from the lighting fixture. Here, the first paths L1, L1A, and L1B shown in FIGS. 6 to 8 are virtual lines showing a part of the path of the white light emitted from the first light source unit 20. Further, the second path L2 shown in FIG. 6 is a virtual line showing a part of the path of the blue light emitted from the second light source unit 30.

The first light source unit 20 emits white light from the first light source module 21 toward the sunlight frame portion 221A of the first light-transmitting portion 22, as shown by the first path L1 in FIG. The light incident on the sun frame part 221A is emitted from the inner surface of the sun frame part 221A. Therefore, white light is emitted diagonally downward toward the opening 131 of the flange portion 13.

In the second light source unit 30, blue light is emitted from the second light source module 37 toward the first end surface 341 of the second light-transmitting section 34, as shown by the second path L2 in FIG. The light incident on the second light-transmitting section 34 travels through the second light-transmitting section 34 while being totally reflected on the upper surface and the lower surface. The light hits the scatterer and is scattered, and is surface-emitted from the lower surface of the second light-transmitting section 34 . The light emitted from the lower surface of the second light-transmitting section 34 passes through the cover section 222 of the first light-transmitting section 22 and is emitted downward toward the opening 131 of the flange section 13 .

Here, with reference to the comparative examples shown in FIGS. 7 and 8, the problems of the comparative examples and the effects of this embodiment will be explained. When the first light source module 21 is disposed above the cover section 222' of the first transparent section 22 as in the first paths L1A and L1B shown in FIG. The white light is reflected on the second transparent section 34. When the cover part 222' is disposed above the frame part 221, the white light emitted from the first light source module 21 passes through the cover part 222' as shown in the first path L1A in FIG. 7(a). A portion of the white light is incident on the upper surface and reflected upward. Therefore, white light is reflected in the second light-transmitting section 34. When the cover part 222' is disposed below the frame part 221, the white light emitted from the first light source module 21 is directed to the sunlight frame part 221A as shown in the first path L1B in FIG. 7(b). enters the back surface of the sun frame section 221A, emits white light obliquely downward toward the opening 131 of the flange section 13, enters the upper surface of the cover section 222', and emits white light from the inner surface of the sun frame section 221A. is reflected upward. Therefore, white light is reflected in the second light-transmitting section 34. As described above, in the lighting fixture 1 of the comparative example, there was a risk that white light would be reflected on the blue light emitting surface of the second light-transmitting section 34, and the design of the second light-transmitting section 34 would be degraded. On the other hand, in the lighting fixture 1 of the first embodiment, the first light source module 21 is arranged below the cover part 222. Therefore, the light emitted from the first light source module 21 does not directly enter the upper surface of the cover part 222. Further, the light emitted from the first light source module 21 and transmitted through the solar frame portion 221A is emitted diagonally downward toward the opening 131 of the flange portion 13. In addition, a part of the light that has passed through the sun frame part 221A is diffused and enters the second light-transmitting part 34, but it enters the second light-transmitting part 34 at a large angle of incidence. The white light reflected in the light section 34 is difficult to block. Therefore, it is possible to suppress the white light emitted from the first light source module 21 from being reflected by the cover part 222 and reflected in the second light-transmitting part 34.

Next, the effects of the lighting fixture 1 of the first embodiment will be explained.

The lighting fixture 1 of the first embodiment includes a box-shaped fixture main body 10 with an opening 131 formed on the lower side, and a flange portion 13 that moves from the lower side to the upper side as it goes inward from the outer edge of the opening 131. A first light-transmitting part 22 which has a frame part 221 provided to protrude in the direction, a cover part 222 provided above the frame part 221, and is provided so as to close the opening part 131 of the instrument main body 10; , a second light-transmitting section 34 disposed above the first light-transmitting section 22 and a second light-transmitting section 34 disposed below the cover section 222 to emit white light, which is the first light, toward the frame section 221. It includes a first light source module 21 and a second light source module 37 that is disposed above the cover part 222 and emits blue light, which is the second light, toward the second light-transmitting part 34. Therefore, in the lighting fixture 1 of the first embodiment, the cover part 222 is disposed between the second transparent part 34 and the opening of the fixture main body 10 to prevent foreign matter from attaching to the second transparent part 34. Scars can be suppressed.

Further, in the lighting fixture 1 of the first embodiment, the second light source module 37 is arranged above the cover part 222, the first light source module 21 is arranged below the cover part 222, and the first light source module 37 is arranged above the cover part 222. It has a frame part 221 that is inclined so that the light emitted by the module is emitted toward the lower side of the instrument main body. Therefore, in the lighting fixture 1 of the first embodiment, since the light emitted from the first light source module is emitted from the frame section 221 to the opening section 131, there is no possibility of foreign matter adhering to the second transparent section 34 or scratches. It is possible to suppress the light from the first light source module 21 from being reflected in the second light-transmitting part 34 while suppressing this.
