Modes for Carrying Out the Invention
[0009] Hereinafter, a lighting fixture 100 which is an example of an embodiment will be described with reference to the drawings. Note that each of the embodiments described below shows an example of the present disclosure. Therefore, the numerical values, components, arrangements and connection forms of components, etc. shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Therefore, among the components in the following embodiments, components not described in the independent claims indicating the highest concept of the present disclosure are described as optional components.
[0010] Note that each figure is a schematic diagram and is not necessarily drawn precisely. In each figure, substantially the same configuration is denoted by the same reference numeral, and redundant descriptions may be omitted or simplified. Also, in this specification, the terms "upper" and "lower" do not necessarily refer to the upward (vertically upward) and downward (vertically downward) directions in an absolute spatial sense.
[0011] Also, the substantially cylindrical holder 30, the fixture body 40, and the frame 50 may be described according to the axial direction (vertical direction), the circumferential direction, or the radial direction.
[0012] [Overall Configuration of Lighting Fixture] The overall configuration of the lighting fixture 100 will be described with reference to FIGS. 1 to 3.
[0013] The lighting fixture 100 is, for example, a downlight that irradiates light downward (floor, ground, wall, etc.). The lighting fixture 100 is disposed, for example, on the ceiling surface CS of a building. The lighting fixture 100 of the present embodiment is a ceiling-embedded type lighting fixture, and is, for example, embedded and disposed in a ceiling-embedded hole formed in the ceiling surface CS. The ceiling-embedded hole of the present embodiment is circular in plan view. Also, the lighting fixture 100 of the present embodiment is a small-diameter lighting fixture disposed in a small-diameter ceiling-embedded hole (for example, 75 mmΦ). However, the lighting fixture of the present disclosure may be disposed on an attachment surface other than the ceiling surface. Also, the present disclosure may be applied to lighting fixtures other than ceiling-embedded type lighting fixtures, and may be applied to lighting fixtures other than downlights.
[0014] The lighting fixture 100 includes a light source 10, a socket 20 in which the light source 10 is mounted, a holder 30 that houses the light source 10 and the socket 20, a fixture body 40 that houses the holder 30 and rotatably supports the holder 30 around a horizontal axis, and a frame body 50 that is provided below the fixture body 40, rotatably supports the fixture body 40 around a vertical axis, and is embedded in a ceiling embedding hole.
[0015] Further, the lighting fixture 100 includes a terminal block 60 to which an internal power line 61 for supplying power to the socket 20 and an external power line 62 for supplying power from the outside are electrically connected, a terminal block base 70 on which the terminal block 60 is placed on the side of the ceiling surface CS where the lighting fixture 100 is embedded, a connecting member 80 that connects the top surface portion 41 of the fixture body 40 and the terminal block base 70 and presses the terminal block base 70 toward the ceiling surface CS, and a mounting spring 90 for fixing the lighting fixture 100 to the ceiling embedding hole.
[0016] [Light source unit] The light source 10 will be described with reference to FIGS. 2 and 4.
[0017] The light source 10 is, for example, an LED (Light Emitting Diode) light source. The light source 10 has a housing 11, a light emitting portion 12 held by the housing 11, a lens 13 disposed below the light emitting portion 12, two power supply pins 14 for receiving power for causing the light emitting portion 12 to emit light, and a drive circuit 15 for driving the light emitting portion 12.
[0018] The housing 11 is a member that forms the outer shell of the light source 10. The housing 11 is made of resin or metal and is formed in a substantially cylindrical shape. The housing 11 holds the light emitting portion 12 and the lens 13. Further, a drive circuit 15 is housed inside the housing 11. A convex portion 11A protruding upward is formed on the top surface of the housing 11. The convex portion 11A is formed in a substantially cylindrical shape. A capacitor 16, which is a part of the drive circuit 15, is housed in the convex portion 11A. With such a configuration, the capacitor 16, which is a high-temperature component compared to other components of the drive circuit 15, can be efficiently cooled.
[0019] The light emitting unit 12 emits light by the power supplied from the drive circuit 15. The light emitting unit 12 emits, for example, white light. The light emitting unit 12 is constituted by, for example, LEDs. The light emitting unit 12 includes a substrate and one or more LED elements mounted on the substrate. The LED element may be a surface mount type LED package or an LED chip.
[0020] The lens 13 is an optical member having translucency and transmits the light emitted from the light emitting unit 12. Further, the lens 13 is a condenser lens that condenses the light emitted from the light emitting unit 12 and is, for example, a Fresnel lens. The lens 13 is constituted by a translucent material having translucency and is constituted by, for example, a transparent resin material such as acrylic or polycarbonate, or a glass material.
[0021] The power supply pin 14 is a conductive pin and receives power for causing the light emitting unit 12 to emit light from outside the light source 10. The power supply pin 14 and the drive circuit 15 are electrically connected by an electric wire (not shown) housed in the housing 11. The power supply pin 14 is a pin having a T-shaped cross section with a disk-shaped enlarged diameter portion at the tip. Also, the interval between the two power supply pins 14 is the same as the interval P between the terminal portions 25B as pin mounting portions, which will be described in detail later.
[0022] Further, the power supply pin 14 is a connection pin for connecting the light source 10 to the socket 20. The power supply pin 14 is electrically connected to the socket 20. Although details will be described later, the power supply pin 14 is locked to the terminal portion 25B as a pin mounting portion of the connection terminal 25 provided on the socket 20 and is electrically and mechanically connected to the terminal portion 25B. Also, when the power supply pin 14 is connected to the terminal portion 25B, the light source 10 is held by the socket 20.
[0023] The drive circuit 15 is a power supply circuit for causing the light emitting unit 12 to emit light, and supplies predetermined power to the light emitting unit 12. The drive circuit 15 has a capacitor 16 which is a high temperature component compared with other components of the drive circuit 15. The drive circuit 15 converts, for example, AC power received at the power supply pin 14 (for example, commercial AC power of AC100V) into DC power, and supplies the DC power to the light emitting unit 12.
[0024] [Socket] The socket 20 will be described with reference to FIGS. 2, 4 to 6.
[0025] As shown in FIGS. 2, 4 to 6, the socket 20 is a member to which the light source 10 is attached as described above. Further, the socket 20 is a member that supplies power to the light source 10. The socket 20 is housed in a holder 30 described later. The socket 20 has a housing 21 and two connection terminals 25, the details of which will be described later.
[0026] As shown in FIGS. 4 to 6, the housing 21 is a member that forms the outer shell of the socket 20. The housing 21 is made of, for example, resin and is formed in a ring shape having a top surface. The housing 21 has an upper cover 21A that covers the upper side of the housing 21 and a lower cover 21B that covers the lower side of the housing 21. Two long holes 22 and a recess 23, the details of which will be described later, are formed in the lower cover 21B. The long holes 22 are formed in a substantially arc shape on the bottom surface of the housing 21. The long holes 22 have a pin insertion hole 22A, a pin mounting hole 22B, and a pin guide hole 22C, the details of which will be described later.
[0027] As shown in FIG. 5, the pin insertion hole 22A is formed with an enlarged diameter at one end of the long hole 22. The pin mounting hole 22B is formed at the other end of the long hole 22 and is formed at a position where the terminal portion 25B as the pin mounting portion of the connection terminal 25 described later is visible. The pin guide hole 22C communicates the pin insertion hole 22A and the pin mounting hole 22B and is formed in an arc shape along the pin guide portion 25C of the connection terminal 25 described later.
[0028] Here, when the light source 10 is attached to the socket 20, the light source 10 is inserted into the socket 20 and rotated with respect to the socket 20, whereby the light source 10 is attached to the socket 20. When the light source 10 is inserted into the socket 20, the power supply pin 14 is inserted into the pin insertion hole 22A of the long hole 22. When the light source 10 is rotated with respect to the socket 20, the power supply pin 14 is guided by the pin guide hole 22C of the long hole 22. After the light source 10 is rotated with respect to the socket 20, the power supply pin 14 reaches the pin mounting hole 22B.
[0029] The recess 23 is formed in the substantially central portion of the socket 20. The recess 23 is formed in a circular shape in plan view. When the light source 10 is attached to the socket 20, the convex portion 11A of the housing 11 of the light source 10 is fitted into the recess 23. Thereby, the capacitor 16, which is a component of the drive circuit 15 of the light source 10, can be accommodated in the substantially central portion of the socket 20, and the space occupied by the light source 10 and the socket 20 can be reduced.
[0030] As shown in FIGS. 5 and 6, the connection terminal 25 is a terminal that supplies the power supplied from the internal power line 61 to the power supply pin 14. The connection terminal 25 is a member made of a conductive metal. The connection terminal 25 is accommodated in the upper cover 21A. The connection terminal 25 is accommodated in the housing 21 at a position corresponding to the long hole 22. The connection terminal 25 has a pin introduction portion 25A, a terminal portion 25B as a pin mounting portion, and a pin guide portion 25C, the details of which will be described later.
[0031] The pin introduction portion 25A is disposed on the way of the pin guide hole 22C of the long hole 22, and is a portion into which the power supply pin 14 is introduced while the light source 10 is being inserted into the socket 20 and rotated.
[0032] As described above, the terminal portion 25B as the pin mounting portion is disposed at a position corresponding to the pin mounting hole 22B of the long hole 22, and is the portion where the power supply pin 14 is locked after the light source 10 is rotated with respect to the socket 20. The terminal portion 25B holds the power supply pin 14 and is electrically connected to the power supply pin 14. Further, the terminal portion 25B is electrically connected to the internal power line 61, and the internal power line 61 and the power supply pin 14 are electrically connected via the terminal portion 25B. Also, when the power supply pin 14 is locked to the terminal portion 25B, the light source 10 is held by the socket 20.
[0033] Here, the terminal portion 25B as the pin mounting portion is arranged such that the interval P between the terminal portions 25B is 25 to 40 mm, preferably such that the interval P between the terminal portions 25B is 25 to 30 mm. Thereby, when the light source 10 is mounted on the socket 20, the fixing stability of the light source 10 with respect to the socket 20 can be improved.
[0034] Also, the terminal portion 25B as the pin mounting portion is arranged such that when a JIS standard test finger contacts the pin mounting hole 22B of the long hole 22, the test finger does not contact the terminal portion 25B. Thereby, accidents such as electric shock when removing the light source 10 from the socket 20 or attaching (mounting) the light source 10 to the socket 20 can be prevented.
[0035] The pin guide portion 25C is disposed at a position corresponding to the pin guide hole 22C of the long hole 22 as described above, and is the portion where the power supply pin 14 is guided when the light source 10 is rotated with respect to the socket 20.
[0036] [Holder] Once again, the holder 30 will be described with reference to FIGS. 2, 3 and 7.
[0037] As described above, the holder 30 is a member that houses the light source 10 and the socket 20. Further, the holder 30 is supported rotatably about a horizontal axis inside the appliance body 40. The holder 30 is made of, for example, resin. The holder 30 has a cylindrical main body 31, a top surface portion 32 to which the socket 20 is fixed on the lower surface (inner surface), and a rotation shaft 33 that protrudes horizontally at the lower end portion of the main body 31 and at the radially outer end portion.
[0038] Note that since the rotation shaft 33 of the holder 30 is offset from the center of the holder 30 in plan view, the holder 30 rotates from the vertical direction to a predetermined angle on one side (the side where the appliance body 40 described later is refracted) (see FIG. 3). However, although details will be described later, since the holder 30 can rotate about a vertical axis together with the appliance body 40, it can rotate about a horizontal axis from the vertical direction to a predetermined angle on the other side.
[0039] [Appliance body] Again, the appliance body 40 will be described with reference to FIGS. 1 to 3 and FIG. 7.
[0040] As described above, the appliance body 40 is a member that houses the holder 30 and supports the holder 30 rotatably about a horizontal axis. Further, the appliance body 40 is supported rotatably about a vertical axis by a frame body 50 provided below the appliance body 40. The appliance body 40 is a metal member such as aluminum, for example, and is formed by die casting. The appliance body 40 is formed in a cylindrical shape having a top surface portion 41 and is refracted in a U shape on the side surface.
[0041] In recent years, the ceiling embedding hole of the downlight has been further reduced in diameter. However, in a lighting fixture, in order to secure a rotation angle (hereinafter, the swing angle) of, for example, rotating a light source about a horizontal axis to a predetermined angle or more, a space (the gap between the light source and the appliance body in the radial direction) where the upper part of the light source can be inclined is required above the light source. However, when the diameter of the downlight is reduced, it is necessary to reduce the outer shape of the light source and increase the overall length, and it has been difficult to secure the above space.
[0042] According to the lighting fixture 100 of the present embodiment, as described above, since the fixture body 40 is bent in a U shape on the side surface, the swinging angle of the light source 10 can be ensured even with a small diameter.
[0043] The fixture body 40 has a holder support portion 42, a rotation support portion 43, and a frame support portion 44, the details of which will be described later. The holder support portion 42 is formed inside the fixture body 40 and rotatably supports the rotation shaft 33 of the holder 30. The rotation support portion 43 is provided on the top surface portion 41 of the fixture body 40, supports the fixture body 40 so as to be rotatable around the vertical axis, and the connection member 80 is connected thereto. The frame support portion 44 is formed at the lower end portion of the fixture body 40 and is rotatably supported around the vertical axis by a fixture body support portion 53 via a spacer 55 described later.
[0044] Conventionally, in order to rotate the light source around the vertical axis, a rotation support member for rotatably supporting the light source around the vertical axis was provided above the light source. Here, as described above, in recent years, the diameter of the ceiling embedding hole of the downlight has been reduced. However, in order to maintain the heat dissipation performance of the lighting fixture, the lighting fixture itself could not be made smaller. Therefore, in order to reduce the diameter of the lighting fixture, it was necessary to increase the height of the lighting fixture. For this reason, it was difficult to provide a rotation support member above the light source.
[0045] According to the lighting fixture 100 of the present embodiment, as described above, by configuring the fixture body 40 to be rotatable, the light source 10 can be rotated around the vertical axis without providing a rotation support member above the light source 10.
[0046] [Frame] Once again, the frame 50 will be described with reference to FIGS. 1 to 3 and FIG. 7.
[0047] As described above, the frame body 50 is a member that rotatably supports the instrument body 40 around the vertical axis and is embedded in the ceiling embedding hole. The frame body 50 is a metal member such as aluminum, for example, and is formed by die casting. The frame body 50 is formed in a substantially cylindrical shape having a flange portion 51 at the lower end. The frame body 50 has a spring holding portion 52, an instrument body support portion 53, and a spacer 55, the details of which will be described later.
[0048] The spring holding portion 52 is a flat portion formed on the side circumferential surface of the frame body 50 and holds the mounting spring 90. A pair of engaging portions 52A with which the mounting spring 90 engages are formed on the spring holding portion 52. The engaging portion 52A is formed in an L shape that protrudes outward from the spring holding portion 52 in a cross-sectional view perpendicular to the vertical direction and is bent toward the other engaging portion 52A.
[0049] The instrument body support portion 53 is formed at the upper end of the frame body 50 and is a portion that rotatably supports the frame support portion 44 of the instrument body 40 around the vertical axis via a spacer 55 described later. The spacer 55 is a member interposed between the instrument body support portion 53 and the frame support portion 44. The spacer 55 is made of resin, for example, and is formed in an annular shape. According to the spacer 55, it is possible to avoid the generation of dust and the like due to the sliding between the metal frame body 50 and the metal instrument body 40, or to realize smooth sliding.
[0050] [Terminal block] The terminal block 60 will be described with reference to FIGS. 1 to 3.
[0051] As described above, the terminal block 60 is a member to which an internal power line 61 for supplying power to the socket 20 and an external power line 62 for supplying power from the outside are electrically connected. Further, the terminal block 60 is placed on a terminal block base 70 described later. By adopting such a configuration, for example, compared with a lighting fixture in which the terminal block is arranged above the socket, the height of the lighting fixture 100 can be designed to be smaller.
[0052] [Terminal block base] The terminal block base 70 will be described with reference to FIGS. 1 to 3.
[0053] The terminal block base 70 is a member on which the terminal block 60 is placed on the back side of the above-described ceiling surface CS (the side where the lighting fixture 100 is embedded). The terminal block base 70 is made of, for example, metal and is formed by pressing. According to the terminal block base 70, an insulation distance between the terminal block 60 and the ceiling surface CS can be ensured.
[0054] [Connection member] The connection member 80 will be described with reference to FIGS. 1 to 3.
[0055] As described above, the connection member 80 is a member that connects the top surface portion 41 of the fixture body 40 and the terminal block base 70. Further, the connection member 80 constantly presses the terminal block base 70 toward the ceiling surface CS (downward). Thereby, when the light source 10, the socket 20, the holder 30, and the fixture body 40 rotate around the vertical axis, the terminal block 60, the terminal block base 70, and the connection member 80 do not rotate together with the light source 10, the socket 20, the holder 30, and the fixture body 40, and the heat insulating material or the like provided on the back side of the ceiling surface CS does not peel off.
[0056] The connection member 80 is an elastic member and is, for example, a leaf spring formed of a long metal plate. One end of the connection member 80 is fixed to the rotation support portion 43 of the fixture body 40. On the other hand, the other end of the connection member 80 is fixed to the terminal block base 70. The connection member 80 is formed to be inclined from the top surface portion 41 of the fixture body 40 toward the terminal block base 70. The connection member 80 has a wire locking portion 81 for locking the external power supply wire 62. The wire locking portion 81 is formed in an L shape that protrudes and is bent outward (toward the terminal block 60 side) in a vertical cross-sectional view along the longitudinal direction of the connection member 80.
[0057] [Mounting spring] The mounting spring 90 will be described with reference to FIGS. 1 to 3.
[0058] The mounting spring 90 is a member that fixes the lighting fixture 100 to the ceiling recessed hole. In this embodiment, for example, two mounting springs 90 are held by the spring holding portions 52 of the frame body 50. The mounting spring 90 is an elastic member, for example, a leaf spring formed by a long metal plate. When fixing the lighting fixture 100 to the ceiling recessed hole, the flange portion 51 of the frame body 50 is locked to the ceiling surface CS, and the mounting spring 90 is elastically deformed between the spring holding portion 52 of the frame body 50 and the inner surface of the ceiling recessed hole, and the lighting fixture 100 is fixed to the ceiling recessed hole by utilizing the restoring force of the mounting spring 90.
