  However, in the above-described conventional lighting fixture, the elastic member may deteriorate over time due to heat or the like due to long-term use. In this case, for example, in the case of maintenance such as lamp replacement or internal cleaning, the cover member is rotated and removed from the instrument body. At this time, due to deterioration of the elastic member, the adhesion between the instrument body and the instrument mounting surface is reduced. Is lowered and the fixed state is not maintained, and a phenomenon occurs in which the instrument main body also rotates with the rotation of the cover member.

Moreover, the adapter A electrically and mechanically connected to the hooking sealing body Cb installed in the ceiling surface C as an instrument mounting surface is provided. Such a lighting fixture is formed in a round and circular appearance, and the front side is a light irradiation surface and the back side is a mounting surface to the ceiling surface C.

  As shown in FIGS. 2 to 6, the main body 1 is a chassis formed in a circular shape from a flat plate of a metal material such as a cold-rolled steel plate, and is provided with a mounting portion 6 to be described later at a substantially central portion. The circular opening 11 is formed. Further, on the outer peripheral side of the flat portion 12 on the inner surface side to which the light source unit 2 is attached, a stepped portion 13 is formed toward the back side to form a bowl-shaped concave portion 14. A cover receiving member to which the cover member 7 is detachably attached is disposed at the step portion 13. More specifically, the cover receiving member is a cover metal fitting 75, and is arranged in the concave portion 14 formed by the stepped portion 13.

  As shown in FIGS. 4 to 6, lighting fixture mounting spring members 15 are provided at four locations on the back side of the main body 1. As shown with reference to FIGS. 8 and 9, the spring member 15 is made of metal such as stainless steel and is formed by bending a substantially rectangular plate spring. A fixing portion 15a is formed on one end side of the spring member 15, and the fixing portion 15a extends in a rectangular shape in the horizontal direction in the drawing. Further, a screw through hole 15b is formed in the fixing portion 15a.

  Further, an extending portion 15c is formed obliquely upward from the fixed portion 15a, and a contact portion 15d having a quadrangular shape is formed on the tip side, that is, the other end side. The angle θ formed by the contact portion 15d and the extension portion 15c is preferably set to about 130 ° to 160 °, and is set to 145 ° in this embodiment (see FIG. 9C). . By setting the angle in this manner, the contact portion 15d can be contacted with the ceiling surface C in a substantially planar manner, for example.

Further, a rectangular parallelepiped sponge is provided on the contact portion 15d as an anti-slip portion 15e by adhesion or the like. In addition, as the non-slip | skid part 15e, other members, such as silicone rubber, are applicable. Further, for example, the non-slip portion 15e may be formed by directly processing the contact portion 15d.
Therefore, the abutting portion 15d means a portion that abuts the ceiling surface C indirectly or directly.

  As shown in FIG. 4, a plurality of lighting fixture mounting spring members 15 formed in this manner are arranged on the back side of the main body 1 in a substantially radial manner centering on the central mounting portion 6. Specifically, the fixing portion 15a of the spring member 15 is fixed to the main body 1, the contact portion 15d is directed in the outer peripheral direction, and the longitudinal direction is disposed along the substantially radial direction. The fixing portion 15a is fixed by a screw that passes through the screw through hole 15b at the same time that the lighting device cover 5 described later is attached to the main body 1.

  As representatively shown in FIG. 6, the spring member 15 disposed on the back side of the main body 1 can be elastically deformed with a spring action in the front side direction (arrow direction shown in the drawing) with the fixing portion 15 a as a fulcrum. Yes.

  As shown in FIGS. 2, 3, and 5 to 7, the light source unit 2 includes a substrate 21 and a plurality of light emitting elements 22 mounted on the substrate 21 (the light emitting elements 22 in FIG. 2). Is omitted). The substrate 21 is disposed so that four arc-shaped substrates 21 having a predetermined width dimension are connected to each other, and is formed in a substantially circle shape as a whole. That is, the substrate 21 formed in a substantially circle shape as a whole is composed of four divided substrates 21.

  By using the substrate 21 thus divided, it is possible to suppress the deformation of the substrate 21 by absorbing thermal contraction at the divided portion of the substrate 21. In addition, although it is preferable to use the board | substrate 21 divided | segmented into plurality, you may make it use the board | substrate of 1 sheet integrally formed in the substantially circle shape.

  The board | substrate 21 consists of a flat plate of the glass epoxy resin (FR-4) which is an insulating material, and the wiring pattern is formed with the copper foil on the surface side. Further, a white resist layer acting as a reflective layer is applied on the wiring pattern, that is, on the surface of the substrate 21. The material of the substrate 21 can be a ceramic material or a synthetic resin material when an insulating material is used. Furthermore, when it is made of metal, a metal base substrate in which an insulating layer is laminated on one surface of a base plate having good thermal conductivity such as aluminum and excellent heat dissipation can be applied.

  The light emitting element 22 is an LED, which is a surface mount type LED package. A plurality of LED packages are arranged along the circumferential direction of a plurality of circle-shaped substrates 21, that is, in a plurality of rows on a substantially circumference centered on the mounting portion 6, and in this embodiment, two rows on the inner peripheral side and outer peripheral side. Has been implemented. In addition, the LED package has a light emission color of daylight white N and a light bulb color L, which are alternately arranged, and the adjacent light emitting elements 22 in each row are arranged at substantially equal intervals. It is arranged in a space. Color adjustment is possible by adjusting the current flowing through the LED package of daylight white color and bulb color.

  In addition, the light emitting element 22a for nightlights is mounted on the specific substrate 21a (right side in FIG. 3, right upper side in FIG. 7). For the light emitting element 22a, an LED package having the same specifications as the light bulb color of the main light source mounted in a circle is used. Thereby, the common use of the member is achieved.

  The light emitting elements 22 are not necessarily mounted in a plurality of rows. For example, you may make it mount in 1 row along the circumferential direction. The number of columns and the number of the light emitting elements 22 can be appropriately set according to a desired output.

  The LED package is roughly composed of an LED chip disposed in a main body formed of ceramics or synthetic resin, and a translucent resin for molding such as epoxy resin or silicone resin that seals the LED chip. It is configured. The LED chip is a blue LED chip that emits blue light. The translucent resin is mixed with a phosphor so that daylight white or light bulb color light can be emitted.

  In addition, LED may be made to mount an LED chip directly on the board | substrate 21, and you may make it mount a bullet-type LED, and a mounting system and a format are not exceptionally limited.

  The diffusing member 3 is a lens member, and is made of a transparent synthetic resin having an insulating property such as polycarbonate or acrylic resin as shown in FIG. 6, and has a substantially circular shape along the arrangement of the light emitting elements 22. And is disposed so as to cover the entire surface of the substrate 21 including the light emitting element 22.

In addition, the lens member has two ridges in the circumferential direction facing the light emitting element 22 on the substantially circular inner peripheral side portion and outer peripheral side portion, and a continuous ridge portion 31 having a constant cross-sectional shape is continuous. Is formed. A U-shaped groove 32 is continuously formed along the circumferential direction inside the protruding portion 31. Therefore, the U-shaped groove 32 is arranged to face the plurality of light-emitting elements 22, and the plurality of light-emitting elements 22 are accommodated and covered in the U-shaped groove 32. It is in a state.
Further, a flat portion 33 extending in the width direction is formed from the protruding portions 31 so that the entire surface of the substrate 21 is covered.

  According to the lens member configured as described above, the light emitted from the plurality of light emitting elements 22 is diffused and radiated mainly by the protrusions 31 in the inner circumferential direction and the outer circumferential direction on the circumference. That is, the light emitted from the light emitting element 22 is mainly diffused and emitted in the radial direction with the circle-shaped center where the light emitting element 22 is disposed as the origin.

Therefore, it is possible to improve the uniformity of the irradiation light by the light emitted from the plurality of light emitting elements 22 by the lens member. Further, the graininess due to the luminance of each light emitting element 22 can be suppressed.
Moreover, since the flat part 33 is formed in the diffusing member 3 so as to cover the entire surface of the substrate 21, the charging part is covered and protected by the diffusing member 3.

Note that the diffusing member 3 may not be integrally formed in a substantially circle shape. For example, corresponding to the divided substrates 21, the substrates 21 may be divided and formed. In this case, the plurality of light emitting elements 22 mounted on one substrate 21 are continuously covered with the diffusing member 3.
Further, the diffusion member 3 is not limited to a lens member, and a diffusion sheet or the like may be applied.

  As representatively shown in FIGS. 5 and 6, the light source unit 2 configured as described above is such that the substrate 21 is positioned around the mounting unit 6 and the mounting surface of the light emitting element 22 is the front side, that is, It is arranged so as to face the lower irradiation direction. Further, the substrate 21 is attached in surface contact so that the back surface side of the substrate 21 is in close contact with the flat portion 12 on the inner surface side of the main body 1. Specifically, the diffusing member 3 is overlapped from the front side of the substrate 21, and the diffusing member 3 is attached to the main body 1 by a fixing means such as a screw S, so that the substrate 21 is connected to the main body 1 and the diffusing member 3. It is sandwiched between and pressed and fixed. That is, the substrate 21 and the diffusing member 3 are fastened together by one screw S.

  Accordingly, the substrate 21 is thermally coupled to the main body 1 so that heat from the substrate 21 is conducted from the back surface side to the main body 1 and radiated. The surface contact between the substrate 21 and the main body 1 is not limited to the case where the entire surface of the substrate 21 is in contact with the main body 1. It may be a partial surface contact.

  In addition, since the flat portion 33 of the diffusion member 3 is in surface contact with the mounting surface side of the substrate 21, heat is transmitted from the mounting surface side of the substrate 21 to the diffusion member 3 and passes through the diffusion member 3. Heat can be dissipated. That is, heat can be radiated from the front side of the substrate 21.

As shown in FIGS. 2, 3 and 5, the lighting device 4 includes a circuit board 41 and circuit parts 42 such as a control IC, a transformer, and a capacitor mounted on the circuit board 41. The circuit board 41 is formed in a substantially arc shape so as to surround the periphery of the mounting portion 6, and the adapter A side is electrically connected, and is connected to a commercial AC power source via the adapter A. Accordingly, the lighting device 4 receives this AC power supply, generates a DC output, supplies the DC output to the light emitting element 22 via the lead wire, and controls the light emitting element 22 to be turned on.
Such a lighting device 4 is disposed between the attachment portion 6 and the light source portion 2, that is, the substrate 21.

  As shown in FIGS. 2 and 5, the lighting device cover 5 is formed in a substantially short cylindrical shape by a metal material such as a cold rolled steel plate, and is attached to the main body 1 so as to cover the lighting device 4. The side wall 51 is inclined so as to expand toward the back side, and an opening 53 is formed in the front wall 52 so as to correspond to the attachment portion 6. Therefore, a part of the light emitted from the light emitting element 22 is reflected to the front side by the side wall 51 and effectively used. In addition, an arcuate guide recess 54 that is recessed toward the back surface is formed at the periphery of the opening 53.

  The attachment portion 6 is an adapter guide formed in a substantially cylindrical shape, and an engagement port 61 through which the adapter A is inserted and engaged is provided at the center portion of the adapter guide. The adapter guide is disposed corresponding to the opening 11 formed in the central portion of the main body 1. A base is formed on the outer periphery of the adapter guide so as to protrude from the outer periphery, and an electrical auxiliary component 62 such as an infrared remote control signal receiver or an illuminance sensor is disposed on the base. .

  Note that the attachment portion 6 is not necessarily a member referred to as an adapter guide or the like. For example, it may be an opening formed in the main body 1 or the like, and in essence, it means a member or a part that is opposed to the hooking sealing body Cb as a wiring device and to which the adapter A is engaged.

  The cover member 7 is formed in a substantially circular shape from a translucent material such as an acrylic resin, and has a milky white diffusibility, and has a non-translucent circular decorative cover 71 in the center. Is installed. The decorative cover 71 is formed with a light receiving window 72 having a substantially triangular translucency so as to face the electrical auxiliary component 62. Further, a projecting pin 73 projecting in the inner surface direction is formed near the center of the cover member 7 on the inner surface side.

  The cover member 7 is detachably attached to the outer peripheral edge of the main body 1 so as to cover the front side of the main body 1 including the light source section 2. Specifically, by rotating the cover member 7, the cover mounting bracket 74 provided on the cover member 7 is engaged with the cover receiving bracket 75 disposed in the recess 14 in the step portion 13 on the outer peripheral portion of the main body 1. Can be installed by joining. Further, when removing the cover member 7, the cover member 7 can be removed by rotating the cover member 7 in a direction opposite to that at the time of attachment and releasing the engagement between the cover attachment fitting 74 and the cover receiving fitting 75.

  Thus, in the state where the cover member 7 is attached to the main body 1, as shown mainly in FIG. 5, the inner surface side of the cover member 7 comes into surface contact with the front wall 52 of the lighting device cover 5. Therefore, heat generated from the lighting device 4 or the like can be conducted to the lighting device cover 5 and further conducted to the cover member 7 to promote heat dissipation.

  Here, the cover member 7 is rotated and attached to the main body 1. However, it is necessary to align the position of the light receiving window 72 so as to face the electrical auxiliary component 62. For this reason, in this embodiment, although detailed description is abbreviate | omitted, the position control means is comprised by the protrusion pin 73 formed in the cover member 7 side, and the guide recessed part 54 formed in the lighting device cover 5. FIG. . By this position restricting means, the light receiving window 72 is positioned to face the electrical auxiliary component 62, and for example, the infrared remote control signal receiving unit can receive a control signal from the infrared remote control transmitter.

The adapter A is electrically and mechanically connected to a hooking sealing body Cb installed on the ceiling surface C by a hooking blade provided on the upper surface side, and has a substantially cylindrical shape. Is provided so that it always protrudes to the outer peripheral side by a built-in spring. The locking portion A1 is immersed by operating a lever provided on the lower surface side. Further, a power cord for connecting to the lighting device 4 is led out from the adapter A, and is connected to the lighting device 4 via a connector (see FIG. 3).
Next, the attachment state to the ceiling surface C of a lighting fixture is demonstrated with reference to FIG. 10 thru | or FIG.

  First, as shown in FIG. 10, the adapter A is electrically and mechanically connected to the hanging sealing body Cb previously installed on the ceiling surface C. From this state, the fixture body 1 is mounted on the lighting fixture until the engaging portion 61 of the adapter A is securely engaged with the engaging port 61 of the adapter guide while the engaging portion 61 of the adapter guide as the mounting portion 6 is aligned with the adapter A. The mounting operation is performed by manually pushing up from the lower side against the elastic force of the spring member 15.

  Next, as shown in FIG. 11, the cover member 7 is attached to the main body 1. This is attached by rotating the cover member 7 to engage the cover mounting bracket 74 provided on the cover member 7 with the cover receiving bracket 75 of the main body 1.

  This attachment completion state is the state shown in FIG. 12, and in this state, the lighting fixture attaching spring member 15 is elastically deformed from the state shown by the broken line to the state shown by the solid line, and the contact part 15d is the non-slip part 15e. Is in elastic contact with the ceiling surface C. The abutting portion 15d can abut on the ceiling surface C so as to be substantially parallel to the top surface or so that the tip portion is slightly in the vertical direction. Therefore, the luminaire main body 1 is securely fixed to the ceiling surface C by the spring action of the spring member 15.

  Further, when removing the luminaire, it can be removed by removing the cover member 7 and operating the lever provided on the adapter A to disengage the engaging portion A1 of the adapter A.

In the mounting state of the lighting fixture to the ceiling surface C as described above, the lighting fixture mounting spring member 15 is hardly aged due to heat or the like, and stably holds the lighting fixture body 1 on the ceiling surface C. it can. Therefore, for example, when the cover member 7 is rotated and removed from the instrument main body 1, the phenomenon that the instrument main body 1 is also rotated with the rotation of the cover member 7 can be prevented.
Moreover, rotation of the instrument body 1 can be effectively prevented by the friction force by the anti-slip portion 15e.

Furthermore, as representatively shown in FIG. 6, in the mounted state of the lighting fixture, the contact portion 15 d and the back side of the fixture body 1 are configured to maintain a predetermined separation dimension L. For example, it is possible to suppress the heat conducted from the light source unit 2 to the main body 1 from acting directly on the contact portion 15d and the deterioration of the sponge anti-slip portion 15e.
On the other hand, since the lighting fixture attaching spring member 15 has thermal conductivity, heat from the main body 1 is conducted and a heat radiation effect can be obtained.

  Furthermore, since a plurality of the spring members 15 are arranged radially, the stability of the fixed state in the attached state of the main body 1 can be ensured. In addition, since the longitudinal direction of the spring member 15 is arranged along the substantially radial direction, the spring member 15 can be made difficult to visually recognize from the gap between the ceiling surface C and the main body 1, and the appearance is good. can do.

When power is supplied to the lighting device 4 in a state where the lighting fixture is attached to the ceiling surface C, the light emitting elements 22 are energized through the substrate 21 and the light emitting elements 22 are turned on. The light emitted from the light emitting element 22 is diffused in the radial direction by the diffusion member 3 that continuously covers the plurality of light emitting elements 22 and is emitted to the front side. The light emitted to the front side is diffused and transmitted by the cover member 7 and irradiated outward. Therefore, it is possible to improve the uniformity of the irradiated light and to suppress the graininess due to the brightness of each light emitting element 22.
Further, a part of the light traveling toward the inner peripheral side in the radial direction is reflected to the front side by the inclined side wall 51 in the lighting device cover 5 and is effectively used.

  On the other hand, the heat generated from the light emitting element 22 is effectively conducted to the main body 1 because the back side of the substrate 21 is thermally coupled to the main body 1, and is radiated over a wide area. Further, since the step portion 13 is located along the outer periphery of the substrate 21 in the vicinity of the outer peripheral side of the substrate 21, the heat radiation area can be increased by the step portion 13, and the heat dissipation effect at the outer peripheral portion of the main body 1. Can be increased. In addition, a heat dissipation effect can be obtained by heat conduction from the main body 1 to the lighting fixture mounting spring member 15.

  In addition, since the lighting device 4 is disposed between the mounting portion 6 and the substrate 21, the lighting device 4 is reduced from being thermally affected by the substrate 21. This is because the heat of the substrate 21 is conducted toward the outer peripheral direction of the main body 1 and tends to be radiated.

  Further, since the cover member 7 comes into surface contact with the lighting device cover 5, heat generated from the lighting device 4 is conducted to the lighting device cover 5 and further conducted to the cover member 7 for heat dissipation. Can do.

  In addition, since the flat portion 33 of the diffusing member 3 is in surface contact with the mounting surface side of the substrate 21, heat can be radiated from the mounting surface side of the substrate 21 through the diffusing member 3 and also from the front surface side. Become. Further, in this case, since the diffusing member 3 covers the entire surface of the substrate 21, the charging unit is protected.

  As described above, according to the present embodiment, it is possible to provide the lighting fixture mounting spring member 15 and the lighting fixture that can stably hold the fixture body 1 in a fixed state with respect to the fixture mounting surface.

  Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 13 is a rear view of the fixture body 1 and FIG. 14 is a plan view showing an arrangement example of the lighting fixture attaching spring members 15. In addition, the same code | symbol is attached | subjected to the part which is the same as that of 1st Embodiment, or an equivalent part, and the overlapping description is abbreviate | omitted.

In this embodiment, similarly to the first embodiment, a plurality of lighting fixture mounting spring members 15 are arranged on the back side of the fixture body 1 in a substantially radial manner centering on the central mounting portion 6. The spring member 15 is disposed in a different direction. Specifically, the spring member 15 is disposed on substantially the same circumference with the attachment portion 6 as the center, and the extending direction of the contact portion 15d extending from the fixed portion 15a is substantially orthogonal to the radial direction. It is directed in the direction to do. That is, the longitudinal direction of the spring member 15 is arranged in a direction substantially orthogonal to the radial direction.
In addition, the extending direction of the contact portion 15d is directed to the rotating direction when the translucent cover member 7 is attached.

  In addition, although it is preferable that the some spring member 15 is arrange | positioned on substantially the same circumference, each spring member 15 may be arrange | positioned and shifted | deviated from the same circumference. For example, you may make it arrange | position on the circumference which differs for every pair of spring member 15 which opposes (this embodiment 2 sets).

  In such a configuration, for example, when the cover member 7 is attached to the instrument main body 1, the cover mounting bracket 74 provided on the cover member 7 is turned to the main body 1 by rotating the cover member 7 in the direction indicated by the arrow in the figure. Rotating is stopped by engaging with the cover receiving metal fitting 75 disposed in the.

  Although the engagement is thereby completed, there is a case where the cover member 7 is forcibly rotated by force even though the engagement is completed. In such a case, the instrument main body 1 may be rotated with the rotation of the cover member 7.

  However, in this embodiment, since the extending direction of the contact portion 15d is directed in a direction substantially orthogonal to the radial direction, when the force in the rotation direction is applied to the main body 1, the fixed state is firmly established. Can be expected to hold on. In addition, since the extending direction of the contact portion 15d is directed to the turning direction when the translucent cover member 7 is attached, an inadvertent force in the turning direction is applied when the cover member 7 is attached. The main body 1 can be held in a fixed state.

  As described above, according to the present embodiment, in addition to the effects exhibited by the first embodiment, when a force in the rotation direction is applied to the instrument body 1, it can be expected to firmly hold the fixed state.

  In this embodiment, a lighting fixture attaching spring member 152 as shown in FIG. 15 can be applied. In the figure, the same or corresponding parts as those in the first embodiment are denoted by the same or corresponding reference numerals, and detailed description thereof is omitted.

  The spring member 152 has a common fixing portion 152a, and extending portions 152c are formed obliquely upward from both sides of the fixing portion 152a, and a contact portion 152d is formed on the tip side thereof. Has been. That is, a pair of contact portions 152d are formed symmetrically extending from the fixed portion 152a.

According to such a configuration, the extending direction of the abutting portion 152d is directed to both the rotating directions when the translucent cover member 7 is attached and removed, so that the cover member 7 is attached and removed. It can be expected that the fixed state of the main body 1 at the time is firmly held.
Moreover, this lighting fixture attaching spring member 152 is applicable to each of the following embodiments including the first embodiment.
Next, a third embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the part which is the same as that of 1st Embodiment, or an equivalent part, and the overlapping description is abbreviate | omitted.

  In the present embodiment, a plurality of lighting fixture mounting spring members 15 are arranged on the back side of the main body 1 in a substantially radial manner with the mounting portion 6 at the center as the center. It is arranged in the circumferential direction.

According to such a configuration, in addition to being able to achieve the same effects as those of the first embodiment, the attachment operation is performed by manually pushing up the central portion of the fixture body 1 from below during the attachment operation of the lighting fixture. In this case, the operability is improved. Further, since the spring member 15 is disposed in a direction away from the light source unit 2, it is possible to improve the heat dissipation of the heat conducted from the main body 1.
