The lighting fixture 10 according to this embodiment will be described below with reference to FIGS. 1A to 5C.

[1-1. Configuration of lighting equipment]
FIG. 1A is a perspective view showing the appearance of lighting fixture 10 according to the present embodiment. FIG. 1B is a perspective view showing the appearance of the lighting fixture 10 according to the present embodiment with the fixture cover 300 removed. FIG. 2 is an exploded perspective view showing the configuration of lighting fixture 10 according to this embodiment. FIG. 3 is a plan view showing the appearance of the instrument main body 100 according to the present embodiment. FIG. 4 is a cross-sectional view of the lighting fixture 10 according to the present embodiment taken along line III-III in FIG. 3. Note that FIG. 4 also shows the light source unit 200 attached to the socket 140.

As shown in FIGS. 1A to 2, the lighting fixture 10 according to the present embodiment includes a fixture body 100, a socket 140, a socket stand 150, a light source unit 200, and a fixture cover 300 (for example, a glove). Be prepared. The lighting fixture 10 is installed on an installation surface such as construction material (for example, a ceiling 500). The lighting fixture 10 is installed at a location exposed to the external environment, such as a ceiling 500 of a common hallway in an apartment building.

The appliance main body 100 is a main body part that is installed on an installation surface and to which the light source unit 200 is detachably attached. The appliance main body 100 is electrically connected to a commercial power source (not shown) via wiring (not shown).

As shown in FIGS. 2 and 3, the device main body 100 includes a main body portion 110 having a bottom surface portion 111 and an annular side wall portion 112 formed to protrude from the outer periphery of the bottom surface portion 111, a first rib 120, and a second rib 120. It has a rib 130.

The bottom part 111 is, for example, a plate-shaped member attached to the installation surface. Further, on the bottom surface portion 111, a socket 140 and a socket stand 150, which will be described below, are arranged. An instrument cover 300 is attached to the side wall portion 112. In the present embodiment, the bottom portion 111 has a circular shape in plan view, and the side wall portion 112 has an annular shape in plan view, but the shapes of bottom portion 111 and side wall portions 112 in plan view are not limited thereto.

The first rib 120 is a protrusion that is disposed between the bottom surface portion 111 and the light emitting portion 200b and protrudes toward the light emitting portion 200b. The first rib 120 is, for example, a columnar protrusion that protrudes from the bottom surface portion 111 toward the light emitting portion 200b. For example, a plurality of first ribs 120 may be arranged. Specifically, a plurality of first ribs 120 may be arranged along the shape of the light emitting section 200b in plan view. For example, three or more first ribs 120 are arranged. For example, three or more first ribs 120 are arranged at regular intervals along the outer circumferential direction of the light emitting part 200b.

In the present embodiment, since the light-emitting portion 200b has an annular shape in plan view, a plurality of first ribs 120 are arranged along the annular shape. Further, the first rib 120 is arranged at a position overlapping the light emitting section 200b in plan view.

As shown in FIG. 4, the light emitting section 200b is arranged apart from the instrument main body 100 (for example, the bottom surface section 111). In other words, a gap is formed between the light emitting part 200b and the instrument main body 100 (for example, the bottom part 111). Therefore, when stress is applied to the bottom part 111 side (Z-axis negative side) with respect to the light emitting part 200b while the light source unit 200 is attached to the appliance main body 100, the socket 140 and the power supply part 200a (hereinafter referred to as charging (also referred to as part), the light emitting part 200b, etc. may be damaged. Therefore, in order to support the light emitting part 200b, that is, to suppress the deformation of the light emitting part 200b toward the bottom surface part 111, the first rib 120 is provided.

The height H1 (length in the Z-axis direction) of the first rib 120 is, for example, smaller than the distance between the bottom surface part 111 and the light emitting part 200b. Further, the height H1 of the first rib 120 is smaller than the height H2 (length in the Z-axis direction) of the second rib 130, for example.

Note that the shape of the first rib 120 is not limited to the above. For example, the first rib 120 may be provided in an annular shape along the shape of the light emitting section 200b in plan view.

As shown in FIGS. 1B and 2, the second rib 130 is an annular projection that surrounds the outer peripheral side surface 200b1 of the light emitting part 200b when the light source unit 200 is detachably attached to the instrument main body 100. In this embodiment, the second rib 130 is an annular projection, but is not limited thereto. In addition, at least one of the height H2 (see FIG. 4) and the width W2 of the gap S2 (see FIG. 5A) between the second rib 130 and the side surface 200b1 of the light emitting section 200b is such that the second rib 130 has a height H2 (see FIG. 4) and a width W2 (see FIG. 111 side surface) so that human fingers do not touch it.

As shown in FIG. 4, the light emitting section 200b is arranged apart from the instrument main body 100 (for example, the bottom surface section 111). In other words, a gap is formed between the light emitting part 200b and the instrument main body 100 (for example, the bottom part 111). That is, if the second rib 130 is not provided, the user can touch the back surface 200b2 of the light emitting section 200b. With the light source unit 200 attached to the instrument body 100, when the user touches the back surface 200b2 of the light emitting section 200b, the light emitting section 200b is exposed to the side opposite to the bottom surface section 111 (the irradiation surface side, the Z-axis positive side). If stress is applied, there is a risk of damaging live parts, etc. Therefore, the second rib 130 is provided to prevent the user from touching the back surface 200b2 of the light emitting section 200b.

Further, as shown in FIGS. 1B, 2, and 4, in this embodiment, the second rib 130 includes a first rib portion 131, a second rib portion 132, and a stepped portion 133. The first rib portion 131 is a portion of the second rib 130 located on the bottom surface portion 111 side and on the light emitting portion 200b side of the light emitting portion 200b. The second rib portion 132 is a portion of the second rib 130 located closer to the bottom portion 111 than the first rib portion 131 . In this embodiment, each of the first rib portion 131 and the second rib portion 132 is provided in an annular shape (for example, an annular shape). The stepped portion 133 is formed on the outer peripheral surface 130a at the boundary between the first rib portion 131 and the second rib portion 132, and extends along the shape of the second rib 130 in a plan view. The step portion 133 is a step in which the outer circumferential surface 130a of the second rib portion 132 is recessed from the outer circumferential surface 130a of the first rib portion 131 toward the light emitting portion 200b. Further, each of the outer circumferential surfaces 130a of the first rib portion 131 and the second rib portion 132 is, for example, a flat surface.

Further, the height H2 of the second rib 130 is, for example, greater than the distance between the bottom surface portion 111 and the light emitting portion 200b. The height H21 of the first rib portion 131 is greater than the height H22 of the second rib portion 132.

Further, as shown in FIG. 2, in this embodiment, the inner peripheral surface 130b of the second rib 130 is flush with the inner peripheral surface 130b. In other words, the second rib portion 132 is a rib that is thinner in thickness (radial length) than the first rib portion 131 .

Note that the second rib 130 is not limited to having the stepped portion 133. In other words, the stepped portion 133 may not be formed on the outer peripheral surface 130a of the second rib 130. For example, the first rib portion 131 and the second rib portion 132 may be formed to have the same thickness (radial length) and to be flush with each other. Further, for example, the second rib 130 may be formed so that the thickness thereof gradually decreases from the bottom surface portion 111 side toward the light emitting portion 200b side. Further, the second rib 130 does not have a convex step on the outer circumferential surface 130a, for example, when going from the bottom surface portion 111 side to the light emitting portion 200b side (from the Z-axis minus side to the Z-axis plus side).

As shown in FIG. 3, the second rib 130 has a pointed portion 131a having a pointed shape in plan view. Specifically, the first rib portion 131 has a peak portion 131a. The first rib portion 131 has an annular shape (for example, an annular shape) in a plan view, and a tip portion 131a is formed in a part of the annular shape. Note that the peak 131a is not limited to having a sharp top (portion on the positive side of the Y-axis), and may be arcuate with a larger curvature than the curvature of the portion where the peak 131a is not formed.

For example, one peak portion 131a is provided on the first rib portion 131. Further, the peak portion 131a is provided in the first rib portion 131 so as to extend along the Z-axis. Further, the peak portion 131a may be formed across the second rib portion 132.

Further, in a plan view, a water draining portion 130c is formed on the second rib 130 on the opposite side to the position where the peak portion 131a is formed. For example, in a plan view, the apex 131a, the center of the second rib 130, and the drain portion 130c are arranged in this order on a straight line. In the example of FIG. 3, the drain portion 130c is a notch formed in the second rib 130. For example, the notch may be large enough to prevent the user from touching the back surface 200b2 of the light emitting section 200b. Further, the water draining portion 130c is not limited to being a cutout, and may be, for example, a through hole.

Further, the main body portion 110 may be formed with a drain port 113 (drain hole) for draining water inside the lighting fixture 10 to the outside.

Although an example in which the main body portion 110 has both the first rib 120 and the second rib 130 will be described, it is sufficient that the main body portion 110 has at least one of the first rib 120 and the second rib 130.

The main body portion 110 is made of, for example, a resin material or a metal material. The main body portion 110 may be, for example, a resin molded product. In this case, the bottom part 111, the side wall part 112, the first rib 120, and the second rib 130 are integrally formed.

As shown in FIGS. 2 and 3, the socket 140 fixes the light source unit 200 and supplies power for the light source unit 200 to emit light. The socket 140 is fixedly arranged on the bottom part 111. An opening 141 is formed in the socket 140, and by rotating the light source unit 200 with respect to the socket 140 with an electrode pin (not shown) of the light source unit 200 inserted into the opening 141, the light source unit 200 is rotated. It is attached to the socket 140. That is, the light source unit 200 is attached to the instrument main body 100.

The socket stand 150 is a plate-shaped member that is disposed between the bottom portion 111 and the socket 140 and to which the socket 140 is attached. As shown in FIG. 4, in this embodiment, socket stand 150 is provided so that at least a portion thereof overlaps with light emitting section 200b in plan view. The socket stand 150 is fixed to the bottom part 111.

As shown in FIGS. 1B and 2, the light source unit 200 receives power from the socket 140 and emits light. The light source unit 200 is detachably attached to the socket 140. The light source unit 200 includes a power source section 200a that is detachably attached to the socket 140, a light emitting section 200b, and a connecting section 200c that connects the power source section 200a and the light emitting section 200b.

As shown in FIG. 4, the power supply section 200a includes a power supply unit 211, a cap 212, a circuit cover 213 on which the cap 212 is disposed, and a first main body section 210 on which the circuit cover 213 is disposed. , and a translucent first cover section 220 that covers the first main body section 210. For example, the circuit cover 213 is detachably attached to the first main body portion 210. The first cover part 220 is attached to the first main body part 210.

Further, the first main body portion 210 has, for example, an electrode pin that is provided to protrude from the base 212 and receives power from the appliance main body 100 to cause the light source unit 200 to emit light. The cap 212 is, for example, a GX53 type or an E type cap, but is not limited thereto. The power supply unit 211 has a circuit for generating electric power for causing the light source unit 200 to emit light. The circuit converts AC power supplied via wiring from the above-mentioned commercial power source into DC power. The DC power generated by the power supply unit 211 is supplied to the light emitting module 231 included in the light emitting section 200b, so that the light emitting section 200b emits light.

The light emitting section 200b is a light source of the light source unit 200. The light emitting section 200b is provided so as to surround the power source section 200a in a plan view when the power source section 200a is attached to the socket 140 (in other words, the light source unit 200 is attached to the instrument main body 100). The light emitting section 200b includes a light emitting module 231, a second main body section 230 in which the light emitting module 231 is arranged, and a translucent second cover section 240 that covers the light emitting module 231 and is attached to the second main body section 230. has.

The second main body part 230 and the second cover part 240 are, for example, formed in an annular shape. In this embodiment, the second main body part 230 and the second cover part 240 are formed in an annular shape.

The light emitting module 231 is, for example, a light source for emitting white light. White light is, for example, light with a color temperature (correlated color temperature) of 2600K to 7100K. The light emitting module 231 includes a substrate 232 and a plurality of light emitting elements 233 mounted on the substrate 232. The board 232 is a printed wiring board on which a plurality of light emitting elements 233 are mounted. In this embodiment, a plurality of arch-shaped substrates 232 are arranged in a ring.

Further, the light emitting section 200b is arranged closer to the bottom surface section 111 (on the Z-axis negative side and on the installation surface side) than the power supply section 200a when the light source unit 200 is attached to the appliance main body 100, for example. Note that the light emitting section 200b is disposed closer to the bottom surface section 111 than the light emitting section 200b is when at least a part of the light emitting section 200b is disposed closer to the bottom surface section 111 than the light emitting section 200b in the cross section shown in FIG. It means that.

Note that the light source of the lighting fixture 10 is not particularly limited. For example, instead of the above light emitting module, a light emitting module configured using a semiconductor light emitting element such as a semiconductor laser, an organic EL element (OLED), an inorganic EL element, or another solid state light emitting element may be used. . Further, although an example has been described in which the light emitting module emits white light, the emitted light color is not limited to this.

The connecting portion 200c includes a first connecting portion 250 that connects the first body portion 210 and the second body portion 230, and a second connecting portion 260 (third cover portion) that connects the first cover portion 220 and the second cover portion 240. ).

In this way, in the light source unit 200, the light emitting section 200b is arranged around the outer periphery of the power supply section 200a in plan view. Further, in this embodiment, the light source unit 200 is formed with an opening 200d. In the light source unit 200 according to the present embodiment, a power source section 200a and a light emitting section 200b are arranged apart from each other. Wiring for supplying power from the power source section 200a to the light emitting section 200b is arranged inside at least one connecting section 200c. Thereby, it is possible to suppress the heat generated in each of the power supply section 200a and the light emitting section 200b from interfering with each other. For example, circuit components in the power supply section 200a can be prevented from being destroyed due to further warming of the power supply section 200a by the heat from the light emitting section 200b.

Note that the main body part 270 (light source main body part) is formed including the first main body part 210, the second main body part 230, and the first connecting part 250. Further, a light source cover 280 is formed including the first cover part 220, the second cover part 240, and the second connection part 260. The light source cover 280 may have a function of diffusing the light emitted from the light emitting module 231. For example, by attaching a resin containing a light diffusing material (fine particles) such as silica or calcium carbonate, or a white pigment to the inner or outer surface of the light source cover 280 made of transparent glass or resin, milky white light can be produced. A diffusion film is formed on the light source cover 280. Further, the light source cover 280 itself may be molded using a resin material or the like in which a light diffusing material is dispersed. Each of the main body portion 270 and the light source cover 280 is a resin molded product.

As shown in FIGS. 1A and 2, the instrument cover 300 is formed of a translucent member and transmits the light emitted from the light source unit 200. The instrument cover 300 is detachably attached to the instrument body 100 so as to cover the light source unit 200.

The instrument cover 300 may have a function of diffusing the light emitted from the light source unit 200. For example, by attaching a resin containing a light diffusing material (fine particles) such as silica or calcium carbonate, or a white pigment to the inner or outer surface of the instrument cover 300 made of transparent glass or resin, milky white light can be produced. A diffusion membrane is formed on the instrument cover 300. Moreover, the instrument cover 300 itself may be molded using a resin material or the like in which a light diffusing material is dispersed.

The instrument cover 300 and the side wall portion 112 have a mounting structure for detachably attaching the instrument cover 300 to the instrument main body 100. For example, as a mounting structure, one of the instrument cover 300 and the side wall portion 112 is formed with a male thread, and the other is formed with a female thread. The instrument cover 300 is attached to the instrument body 100 by screwing the male and female threads together.

Here, the first rib 120 and the second rib 130 that the instrument main body 100 has will be further explained with reference to FIGS. 5A to 5C. FIG. 5A is a partially enlarged sectional view showing an example of the first rib 120 and the second rib 130 formed on the instrument main body 100 according to the present embodiment. Note that FIG. 5A is a partially enlarged cross-sectional view of the broken line region R1 in FIG. 4 .

As shown in FIGS. 4 and 5A, the first rib 120 protrudes from the bottom surface portion 111 toward the light emitting portion 200b (toward the positive side in the Z-axis direction), and is integrally formed with the second rib 130. ing. The first rib 120 is formed, for example, to protrude from the inner circumferential surface 130b (see FIG. 2) of the second rib 130 toward the center (for example, the socket 140) of the instrument body 100 in a plan view. The first rib 120 is a columnar (for example, rectangular columnar) protrusion. Further, the upper surface 120a of the first rib 120 is, for example, a flat surface. As a result, the contact area of the light emitting section 200b with the back surface 200b2 can be increased, so that stress from the light emitting section 200b can be suppressed from being applied locally to the first rib 120.

For example, the first rib 120 is provided with a gap S1 having a width W1 in a state where the light source unit 200 is attached to the instrument main body 100. The width W1 is the length of the gap S1 in the Z-axis direction. The maximum value of the width W1 is such an interval that the charging part etc. will not be damaged when the light emitting part 200b is deformed by stress with the light source unit 200 attached to the instrument main body 100. The minimum value of the width W1 is preferably such an interval that the light emitting part 200b and the first rib 120 do not physically interfere with each other when the light source unit 200 is attached to the fixture main body 100.

The width W1 may be, for example, a distance that does not physically interfere with the light emitting part 200b and the first rib 120, taking into account dimensional tolerances, thermal expansion, etc. of the instrument main body 100 and the light source unit 200. Note that physical interference here means that when the light source unit 200 is attached to the fixture main body 100, the first rib 120 causes the light emitting part 200b to have a load (on the Z-axis positive side) on the side opposite to the bottom part 111 (Z-axis positive side). means that stress) is applied. The width W1 is, for example, 5 mm or less, more preferably 3 mm or less.

Further, the width W1 may be, for example, such an interval that a person's finger F (for example, the pad of a finger) does not hit the back surface 200b2 of the light emitting part 200b. For example, the finger F conforms to JIS (Japanese Industrial Standards) regulations (for example, JIS C0920) or IEC (International Electrotechnical Commission) standards (for example, IEC 60335-1) The test finger may also be a test finger. For example, finger F may be a jointed test finger with a diameter of 12 mm and a length of 80 mm. Thereby, even without providing the second rib 130, it is possible to suppress the finger F from hitting the back surface 200b2 of the light emitting part 200b.

Note that the first rib 120 and the back surface 200b2 of the light emitting part 200b may be at least partially in contact with each other when the light source unit 200 is attached to the instrument main body 100.

The second rib 130 is provided, for example, with a gap S2 having a width W2 from the side surface 200b1 of the light emitting part 200b when the light source unit 200 is attached to the instrument main body 100. The gap S2 is, for example, an annular (for example, annular) gap in a plan view. The width W2 is the radial length of the gap S2. The maximum value of the width W2 is such that when the light source unit 200 is attached to the instrument body 100, the finger F does not touch the back surface 200b2 of the light emitting section 200b, that is, the finger F does not reach the back surface 200b2 of the light emitting section 200b. It is the interval. For example, the gap S2 is smaller than the finger F in plan view. Further, the minimum value of the width W1 is preferably such an interval that the light emitting part 200b and the second rib 130 do not physically interfere with each other when the light source unit 200 is attached to the fixture main body 100. Furthermore, the width W2 may be such an interval that the light emitting part 200b and the second rib 130 do not physically interfere, taking into consideration the dimensional tolerances, thermal expansion, etc. of the instrument main body 100 and the light source unit 200, for example. Note that physically interfering here means that a load (stress) is applied to the light emitting portion 200b by the second rib 130 while the light source unit 200 is attached to the instrument main body 100. The width W2 is, for example, 1 cm or less, more preferably 5 mm or less.

Further, the second rib 130 may be provided, for example, so as to surround at least a portion of the side surface 200b1 of the second body part 230 of the second body part 230 and the second cover part 240 of the light emitting part 200b. For example, the position of the tip end 132a of the second rib 130 (the end of the second rib 130 on the opposite side to the installation surface) in the Z-axis direction is between the back surface 200b2 and the second main body 230 in the cross section shown in FIG. 5A. The second rib 130 may be provided so as to be located between the first and second cover portions 240 and the boundary B of the second cover portion 240 . In other words, the height H2 of the second rib 130 may be greater than or equal to the distance between the bottom surface portion 111 and the back surface 200b2 and less than or equal to the distance between the bottom surface portion 111 and the boundary B. For example, the second rib 130 may be formed to protrude to a position flush with the boundary B. Thereby, it is possible to suppress the finger F from hitting the back surface 200b2 while suppressing a decrease in the loss of the luminous flux of light from the light emitting part 200b.

Further, the height H2 of the second rib 130 is preferably high, for example, from the viewpoint of further suppressing the contact of the finger F with the back surface 200b2. For example, the second rib 130 is provided so as to surround at least a part of the side surface 200b1 of the second body part 230 and the second cover part 240 of the light emitting part 200b. You can. For example, the second rib 130 may be provided such that the position of the tip 132a of the second rib 130 in the Z-axis direction is located on the opposite side of the bottom surface portion 111 from the boundary B in the cross section shown in FIG. 5A. In other words, the height H2 of the second rib 130 may be greater than the distance between the bottom surface portion 111 and the boundary B.

Furthermore, when the width W2 is narrow (for example, 3 mm or less), the height H2 of the second rib 130 may be smaller than the distance between the back surface 200b2 and the bottom part 111, as long as the finger F does not hit the back surface 200b2.

Such a second rib 130 also functions as a guide when attaching the light source unit 200 to the instrument main body 100. Therefore, the provision of the second rib 130 improves the workability when attaching the light source unit 200.

Further, the stepped portion 133 may be formed, for example, on the outer peripheral surface 130a, closer to the bottom surface portion 111 than the upper surface 120a of the first rib 120.

Although the example in which the first rib 120 and the second rib 130 are integrally formed is described above based on FIG. 5A, the first rib 120 and the second rib 130 are not limited to this, but are spaced apart from each other. may be placed. Further, the first rib 120 is not limited to being provided protruding from the bottom surface portion 111. The first rib 120 has a position or shape that contacts at least a portion of the back surface 200b2 of the light emitting section 200b when stress is applied to the light emitting section 200b toward the bottom surface section 111 side (Z-axis minus side). That's fine. Another example of the first rib 120 will be described with reference to FIGS. 5B and 5C. FIG. 5B is a partially enlarged sectional view showing another example of the first rib 120 formed on the instrument main body 100 according to the present embodiment. FIG. 5C is a partially enlarged sectional view showing still another example of the first rib 120 formed on the instrument main body 100 according to the present embodiment.

As shown in FIG. 5B, the first rib 120 may be provided to protrude from the socket base 150 toward the light emitting section 200b (towards the Z-axis positive side). Further, as shown in FIG. 5C, the first rib 120 may be provided to protrude from the inner peripheral surface 130b of the second rib 130. In the case of FIG. 5C, the first rib 120 is provided so as to protrude from the inner peripheral surface 130b of the second rib 130 toward the light emitting part 200b (in the case of FIG. 5C, toward the X-axis negative side). It's okay to be hit. Further, the first rib 120 may be provided to be spaced apart from the second rib 130 and protrude from the bottom surface portion 111 toward the light emitting portion 200b (toward the Z-axis plus side).

[1-2. Effects, etc.]
As described above, the lighting fixture 10 according to the present embodiment includes the fixture main body 100 having the bottom part 111, the socket 140 disposed on the bottom part 111, the power supply part 200a detachably attached to the socket 140, and , a light source unit 200 having a light emitting section 200b surrounding the power source section 200a in plan view when the power source section 200a is attached to the socket 140. The device main body 100 further includes a first rib 120 that is disposed between the bottom surface portion 111 and the light emitting portion 200b and protrudes toward the light emitting portion 200b.

This allows the first rib 120 to support the light emitting part 200b when stress is applied to the light emitting part 200b on the bottom surface part 111 side while the light source unit 200 is attached to the instrument main body 100. That is, the first rib 120 can suppress deformation of the light source unit 200 due to stress. Therefore, according to the lighting fixture 10 according to the present embodiment, damage to the light source unit 200 and the socket 140 due to stress being applied to the light emitting portion 200b can be suppressed. For example, when installing or replacing the light source unit 200, it is possible to prevent damage to the charging section (power supply section 200a and socket 140) and the light source unit 200 due to inadvertent loading on the light emitting section 200b of the light source unit 200. can do.

Further, the first rib 120 is provided to protrude from the bottom surface portion 111 toward the light emitting portion 200b.

Thereby, for example, when the instrument main body 100 is a resin molded product, the first rib 120 can be easily formed.

Moreover, the lighting fixture 10 further includes a socket stand 150 to which the socket 140 is attached between the socket 140 and the bottom part 111, and which at least partially overlaps with the light emitting part 200b in plan view. . The first rib 120 is provided to protrude from the socket base 150 toward the light emitting section 200b.

Thereby, it is possible to suppress damage to the light source unit 200 and the like due to the first rib 120 provided on the socket stand 150. Furthermore, the height H1 of the first rib 120 can be made smaller than when the first rib 120 protrudes from the bottom surface portion 111. In other words, the amount of material used to form the first ribs 120 can be reduced. Therefore, it is possible to realize the lighting fixture 10 that can suppress damage to the light source unit 200 at a lower cost.

Further, the first ribs 120 are columnar projections, and three or more first ribs 120 are provided along the light emitting section 200b in a plan view.

Thereby, the first rib 120 can be realized at a lower cost than when the first rib 120 is provided in an annular shape. Further, by having three or more first ribs 120, deformation of the light source unit 200 can be effectively suppressed.

Further, the first rib 120 is an annular projection.

Thereby, deformation of the light source unit 200 can be suppressed regardless of the position where a load is applied to the light emitting section 200b. Therefore, damage to the light source unit 200 can be further suppressed.

In addition, the device main body 100 further includes a second rib 130 surrounding the outer peripheral side surface 200b1 of the light emitting section 200b, and at least one of the height H2 and the gap S2 with the side surface 200b1 is the back surface 200b2 of the light emitting section 200b. It has a second rib 130 (an example of the surface on the bottom surface portion 111 side) that is formed so that the finger F of a person (for example, an operator) does not come into contact with it.

Thereby, it is possible to prevent a person from touching the back surface 200b2 of the light emitting section 200b. That is, when a person touches the back surface 200b2 of the light emitting section 200b, stress on the side opposite to the bottom surface section 111 can be suppressed from being applied to the light emitting section 200b. Therefore, damage to the light source unit 200 and the socket 140 due to stress being applied to the light emitting part 200b can be further suppressed. For example, when attaching or replacing the light source unit 200, it is possible to further prevent damage to the charging section (power supply section 200a and socket 140) and the light source unit 200 due to inadvertent application of load to the back surface 200b2 of the light emitting section 200b. can do.

Further, the second rib 130 also functions as a guide when attaching the light source unit 200 to the instrument main body 100.

Further, the width W2 of the gap S2 is smaller than the finger F in plan view.

Thereby, it is possible to suppress the finger F from hitting the back surface 200b2 of the light emitting part 200b due to the gap S2. Furthermore, by narrowing the gap S2 (reducing the width W2), the height H2 of the second rib 130 can be lowered.

Further, the width W2 of the gap S2 is 1 cm or less.

Thereby, it is possible to further suppress the finger F (for example, the pad of the finger) from hitting the back surface 200b2 of the light emitting section 200b.

Further, finger F is a test finger defined by JIS.

Thereby, it is possible to prevent a finger F of a predetermined size from hitting the back surface 200b2 of the light emitting section 200b.

The light emitting unit 200b also includes a light emitting module 231, a second main body part 230 (an example of a main body part) in which the light emitting module 231 is disposed, and a light-transmitting unit that covers the light emitting module 231 and is attached to the second main body part 230. 240 (an example of a cover). The second rib 130 is provided so as to protrude to a position flush with the boundary B between the second main body part 230 and the second cover part 240.

Thereby, it is possible to suppress the loss of the luminous flux of light from the light emitting section 200b, and to prevent the finger F from hitting the back surface 200b2 of the light emitting section 200b.

Furthermore, the light emitting section 200b is arranged closer to the bottom surface section 111 than the power source section 200a in a state where the light source unit 200 is attached to the instrument main body 100.

As a result, the light emitting section 200b is arranged at a position close to the installation surface, so that the lighting effect of the lighting fixture 10 can be enhanced. For example, the light emitting unit 200b can emit light with less uneven brightness.

Moreover, the instrument main body 100 is a resin molded product.

Thereby, the instrument main body 100 can be easily manufactured. For example, the first rib 120 and the second rib 130 do not have a convex portion, a groove portion, or the like that would constitute an undercut. Therefore, the operator can easily take out the instrument body 100 from the mold.

Further, as described above, the lighting fixture 10 according to the present embodiment includes the fixture main body 100 having the bottom part 111, the socket 140 disposed on the bottom part 111, and the power supply part 200a detachably attached to the socket 140. , and a light source unit 200 having a light emitting section 200b surrounding the power source section 200a in a plan view with the power source section 200a attached to the socket 140. The device main body 100 further includes a second rib 130 (an example of a rib) that surrounds the side surface 200b1 on the outer peripheral side of the light emitting portion 200b, and at least one of the height H2 and the gap S2 between the side surface 200b1 and the side surface 200b1 emits light. The second rib 130 is formed so that a person's finger F does not touch the back surface 200b2 (an example of the surface on the bottom surface portion 111 side) of the portion 200b.

Thereby, it is possible to prevent a person from touching the back surface 200b2 of the light emitting section 200b. That is, when a person touches the back surface 200b2 of the light emitting section 200b, stress on the side opposite to the bottom surface section 111 can be suppressed from being applied to the light emitting section 200b. Therefore, damage to the light source unit 200 and the socket 140 due to stress being applied to the light emitting portion 200b can be suppressed. For example, when attaching or replacing the light source unit 200, it is possible to prevent damage to the charging section (power supply section 200a and socket 140) and the light source unit 200 due to an inadvertent load being applied to the back surface 200b2 of the light emitting section 200b. be able to.

Further, the second rib 130 also functions as a guide when attaching the light source unit 200 to the instrument main body 100.

(Embodiment 2)
[2-1. Configuration of lighting equipment]
The lighting fixture according to this embodiment will be described below with reference to FIGS. 6 to 8. The lighting fixture according to this embodiment is used by being attached to, for example, a wall. The lighting fixture according to this embodiment may be the lighting fixture 10 according to Embodiment 1. Below, a case will be described in which the lighting fixture 10 according to Embodiment 1 is attached to a wall. In addition, the following description will focus on the differences from the lighting fixture 10 of Embodiment 1.

FIG. 6 is a cross-sectional view of lighting fixture 10 according to this embodiment when attached to wall 600. FIG. 7 is a partially enlarged sectional view for explaining the position of the stepped portion 133 according to the present embodiment. FIG. 7 is a partially enlarged cross-sectional view of the broken line region R2 in FIG. 6. As shown in FIG. Note that FIG. 7 shows a case where a gap S3 is formed between the instrument body 100 and the instrument cover 300 due to poor attachment (for example, insufficient screwing) between the instrument body 100 and the instrument cover 300. Further, in FIGS. 6 and 7, the Y-axis plus side is the vertically upper side, and the Y-axis minus side is the vertically lower side.

As shown in FIG. 6, the lighting fixture 10 according to the present embodiment is installed on an installation surface (for example, a wall 600) such as construction material. The lighting fixture 10 is installed at a location exposed to the external environment, such as a wall 600 of a common hallway in an apartment building.

As shown in FIGS. 6 and 7, the lighting fixture 10 includes a fixture body 100, a socket 140, a socket stand 150, a light source unit 200, and a fixture cover 300 (for example, a glove), as in the first embodiment. Equipped with. Furthermore, the lighting fixture 10 according to the present embodiment further includes a packing 400 at the joint between the fixture body 100 and the fixture cover 300 for suppressing water from entering from the outside. The packing 400 is provided, for example, in an annular shape. 6 and 7 show an example in which the instrument main body 100 has both the first rib 120 and the second rib 130, the instrument main body 100 according to this embodiment has at least the second rib 120 and the second rib 130. It is sufficient if the rib 130 is provided. Furthermore, a stepped portion 133 is formed in the second rib 130 .

As shown in FIG. 7, if the attachment between the instrument main body 100 and the instrument cover 300 is incorrect, water droplets D may fall onto the second rib 130 through the gap S3. In this case, the second rib 130 functions as a wall that protects the charging section (power supply section 200a and socket 140), etc. from the water droplets D. In this case, from the viewpoint of protecting the live part, the second rib 130 is formed so as to satisfy at least one of a shape and a position that prevent water droplets D from falling onto the live part. The second rib 130 is provided so as to overlap the charging portion, for example, when viewed from the vertically upper side to the vertically lower side (for example, from the Y-axis positive side to the Y-axis negative side). Further, the second rib 130 may be provided, for example, between the vertically upper end 300a of the instrument cover 300 or the gap S3 and the charging part.

Therefore, the second rib 130 is not limited to having an annular shape in plan view as described in Embodiment 1, but may have an arc shape (for example, an arch shape). The second rib 130 according to the present embodiment is a rib formed to protrude from the bottom surface part 111 toward the light emitting part 200b, and is a rib that surrounds at least a part of the side surface 200b1 on the outer peripheral side of the light emitting part 200b. good.

When the second rib 130 has an arcuate shape in plan view, the stepped portion 133 may be formed from one end of the second rib 130 in the circumferential direction to the other end. Further, when the second rib 130 is annular, the stepped portion 133 may be formed in an annular shape extending in the circumferential direction of the second rib 130.

Note that the water droplets D are formed by condensed water or water that has entered between the device main body 100 and the device cover 300, or the like. FIG. 7 shows an example in which water droplets D are formed when water that has entered between the device main body 100 and the device cover 300 falls from the gap S3.

When the water droplet D falls on the second rib 130, most of the water droplet D flows along the circumferential direction of the second rib 130. The water droplets D flowing in the circumferential direction of the second rib 130 are then discharged to the outside of the lighting fixture 10 via the water drain portion 130c and the drain port 113.

In this embodiment, the device main body 100 is attached to the wall 600 so that the drain portion 130c of the second rib portion 132 is on the vertically lower side. In other words, the instrument main body 100 is attached to the wall 600 so that the apex 131a of the second rib 130 is on the vertically upper side. Therefore, at the position where the water droplet D falls on the second rib 130, a pointed portion 131a having a pointed shape in plan view is arranged. Thereby, the water droplets D that have fallen onto the second ribs 130 can further flow in the circumferential direction of the second ribs 130.

However, some of the water droplets D may flow in the height direction (Z-axis direction) of the second rib 130. The stepped portion 133 has a function of suppressing water droplets D flowing in the height direction of the second rib 130 from falling from the tip portion 132a of the second rib 130. If there is a level difference on the path through which the water droplet D flows, the water droplet D will move along the direction in which the level difference is formed (in this embodiment, the circumferential direction of the second rib 130) due to the influence of surface tension, etc. It has the property of expanding and flowing. Therefore, the step portion 133 according to the present embodiment, which extends in the circumferential direction of the second rib 130, is configured to, for example, as shown in FIG. The water droplets D can be caused to flow in the circumferential direction of the second rib 130. FIG. 8 is a diagram showing the flow of water droplets D when they fall on the second rib 130 according to the present embodiment when attached to the wall 600. The arrows shown in FIG. 8 indicate the flow of water droplets D.

Note that the position where the step portion 133 in the second rib 130 is formed is preferably closer to the light emitting portion 200b than the position P where the water droplet D falls on the second rib 130. For example, the position P is the point where the water droplet D falls from the end 300a of the instrument cover 300 on the bottom surface 111 side toward the second rib 130. Note that the point where the water droplet D falls includes a point where the water droplet D is estimated to fall.

Further, when the second rib 130 is provided so as to surround the side surface 200b1 of the light emitting section 200b, it is preferably formed so that the water droplet D does not fall from the tip 132a of the second rib 130 to the boundary B. The tip 132a of the second rib 130 may not be flush with the boundary B, for example. The height H2 of the second rib 130 may be a length other than the distance between the bottom surface portion 111 and the boundary B. For example, the second rib 130 may be formed to surround both the second cover part 240 and the second main body part 230. Thereby, it is possible to suppress the water droplet D from falling from the tip 132a of the second rib 130 to the boundary B of the light emitting part 200b. That is, it is possible to prevent the light emitting unit 200b (for example, the light emitting module 231) from malfunctioning due to the water droplets D.

Note that, in FIGS. 6 and 7, an example has been described in which one stepped portion 133 is formed on the outer peripheral surface 130a of the second rib 130, but the present invention is not limited thereto. Two or more second ribs 130 may be formed closer to the tip 132a of the second rib 130 than the position P where the water droplet D falls. In this case, in each of the two or more step portions 133, a rib portion disposed on the bottom portion 111 side with respect to one step portion 133 and a rib portion disposed on the tip portion 132a side with respect to the one step portion 133. This is a step in which the outer circumferential surface 130a of the rib portion on the tip end 132a side is recessed. For example, in the cross section shown in FIG. 7, the outer circumferential surface 130a of the second rib 130 may have a stepped shape that descends from the bottom portion 111 side toward the tip portion 132a side.

Note that, as shown in FIG. 7, a drain port 114 (drain hole) may be formed in the device main body 100 at a portion on the positive side of the Y-axis. For example, the appliance main body 100 may be attached to the wall 600 so that the drain portion 130c of the second rib portion 132 is on the vertically lower side, and a drain port may be formed in the vertically upper portion. When such a lighting fixture 10 is attached to a ceiling or the like, the drain port 114 can be used as a drainage hole in the side wall portion 112.

[2-2. Effects, etc.]
As described above, the lighting fixture 10 according to the present embodiment includes the fixture main body 100 having the bottom part 111, the socket 140 disposed on the bottom part 111, the power supply part 200a detachably attached to the socket 140, and , a light source unit 200 having a light emitting section 200b surrounding the power source section 200a in plan view when the power source section 200a is attached to the socket 140. The device main body 100 further includes a second rib 130 (an example of a rib) formed to protrude from the bottom surface portion 111 toward the light emitting portion 200b, and a second rib 130 (an example of a rib) that surrounds at least a portion of the side surface 200b1 on the outer peripheral side of the light emitting portion 200b. It has two ribs 130. The second rib 130 has a stepped portion 133 in which the outer circumferential surface 130a on the light emitting part 200b side is recessed from the outer circumferential surface 130a on the bottom surface part 111 side.

For example, the second rib 130 includes a first rib section 131 disposed on the light emitting section 200b side, a second rib section 132 disposed on the bottom surface section 111 side from the first rib section 131, and the first rib section 131 and the second rib section 132 disposed on the bottom surface section 111 side. A stepped portion 133 is formed on the outer circumferential surface 130a of the boundary of the second rib portion 132 and extends along the shape of the second rib 130 in a plan view, and the outer circumferential surface 130a of the first rib portion 131 is The second rib portion 132 has a stepped portion 133 recessed from the outer circumferential surface 130a of the second rib portion 132 toward the light emitting portion 200b.

As a result, the flow direction of the water droplet D that falls on the second rib 130 and flows in the height direction of the second rib 130 (the Z-axis direction, which is the direction toward the light emitting part 200b) is changed to the direction along the step part 133. It can be changed. Therefore, it is possible to suppress water droplets D that have fallen toward the charging section (power supply section 200a and socket 140) from falling onto the charging section.

Further, the stepped portion 133 is arranged closer to the light emitting portion 200b than the position P where the water droplet D falls on the second rib 130.

Thereby, water droplets D flowing in the height direction of the second rib 130 can be effectively caused to flow in the circumferential direction of the second rib 130.

Furthermore, the lighting fixture 10 further includes a translucent fixture cover 300 that covers the light source unit 200 and is attached to the fixture body 100. The position P is the point where the water droplet D falls from the end 300a of the instrument cover 300 on the bottom surface 111 side toward the second rib 130.

Thereby, water droplets D that have fallen from the instrument cover 300 toward the charging section can be suppressed from falling onto the charging section. For example, water that has entered through a gap between the instrument cover 300 and the instrument body 100 caused by poor attachment between the instrument cover 300 and the instrument body 100 can be prevented from falling into the charging part.

Further, the second rib 130 has an arcuate shape in plan view, and includes a first rib portion 131 closer to the bottom portion 111 than the stepped portion 133 and a second rib portion 132 closer to the light emitting portion 200b than the stepped portion 133. The first rib portion 131 has a pointed portion 131a at position P that has a pointed shape in plan view.

Thereby, the water droplets D that have fallen onto the second ribs 130 can be efficiently flowed in the circumferential direction of the second ribs 130. Therefore, the charging part can be protected even more effectively.

Further, the second rib 130 is formed in an annular shape surrounding the outer peripheral side surface 200b1 of the light emitting portion 200b. The stepped portion 133 is formed in an annular shape extending in the circumferential direction of the second rib 130.

Thereby, it is possible to suppress water droplets D from falling on the charging portion, regardless of the attachment position in the rotational direction in a plan view of the device main body 100. For example, even if the device main body 100 is not installed in the correct mounting direction (for example, the device main body 100 is installed with the drain port 113 facing vertically upward), it is possible to protect the live part from water droplets D. can.

Furthermore, the lighting fixture 10 is attached to a wall 600.

Thereby, when attached to the wall 600, the charging part can be protected from water droplets D falling vertically downward.

(Other embodiments)

The light source unit 200 does not need to have the opening 200d. For example, the power supply section 200a and the light emitting section 200b do not need to be placed apart from each other. For example, the power supply section 200a and the light emitting section 200b may be arranged in one housing.

Further, in each of the above embodiments, an example in which no light emitting module is disposed in the power supply section 200a has been described, but the present invention is not limited to this.
