[0008] Hereinafter, lighting devices according to embodiments of the present invention will be described in detail with reference to the drawings. Note that each of the embodiments described below represents a specific example of the present invention. Therefore, the numerical values, shapes, materials, components, component arrangements and connection forms, steps, and step sequences shown in the following embodiments are merely examples and are not intended to limit the present invention. Therefore, among the components in the following embodiments, components not recited in the independent claims will be described as optional components.

[0009] Furthermore, each figure is a schematic diagram and is not necessarily an exact illustration. Therefore, for example, the scales of the figures do not necessarily match. Furthermore, in each figure, substantially the same components are given the same reference numerals, and redundant explanations are omitted or simplified.

[0010] Furthermore, in this specification, terms indicating the relationship between elements, such as vertical, terms indicating the shape of elements, such as cylindrical, and numerical ranges are not expressions that only express a strict meaning, but are expressions that also include a substantially equivalent range, for example, a difference of about a few percent.

[0011] Furthermore, in this specification, ordinal numbers such as "first" and "second" do not refer to the number or order of components unless otherwise specified, but are used for the purpose of avoiding confusion and distinguishing between components of the same type.

[0012] (Embodiment) [composition] First, the configuration of the lighting device according to the embodiment will be described with reference to FIGS.

[0013] 1 and 2 are perspective views of a lighting device 1 according to this embodiment. Specifically, FIG. 1 is a perspective view of the lighting device 1 as viewed from the light emission side. FIG. 2 is a perspective view of the lighting device 1 as viewed from the attachment side to a fixture (the side opposite to the light emission side). FIG. 3 is a cross-sectional view of the lighting device 1 according to this embodiment.

[0014] 1 to 3, the lighting device 1 is a lamp having a flat overall shape. Note that "flat shape" means a shape in which the height (e.g., the maximum length in the vertical direction) is shorter than the width (e.g., the maximum length in the horizontal direction). The external size of the lighting device 1 is, for example, φ70 mm.

[0015] The lighting device 1 is a replaceable lamp that is attached to a socket of a lighting fixture that is recessed into a ceiling or the like. The lighting device 1 is configured to be detachable from the socket. Note that "detachable" means that it can be attached and detached without disassembly or assembly. Specifically, the lighting device 1 has a base (specifically, a conductive pin 80) that fits into the socket. The base of the lighting device 1 according to this embodiment is a Gx53 base. Note that the base of the lighting device 1 is not limited to this, and other bases such as a GH76p base may also be used.

[0016] Furthermore, the lighting device 1 has at least one of dimming and color-adjusting functions. That is, the lighting device 1 can adjust at least one of the brightness and color of the emitted illumination light. However, the lighting device 1 may be a lamp that cannot be dimmed or color-adjusted.

[0017] 1 to 3, the lighting device 1 includes a light source unit 10, a module plate 15, a power supply unit 20, a control unit 30, a connector 40, a housing 50, an operation switch 60, an insulating plate 70, conductive pins 80, and a light-transmitting cover 90. The housing 50 and the light-transmitting cover 90 form an enclosure of the lighting device 1. The operation switch 60 is exposed on the outer surface of the lighting device 1 and is provided so that it can be operated by a person from the outside.

[0018] The light source unit 10 is a light-emitting module that emits light. For example, the light source unit 10 emits white light. The light emitted by the light source unit 10 is radiated to the outside of the lighting device 1 through the light-transmitting cover 90.

[0019] 3, the light source unit 10 includes a substrate 11 and a light emitting element 12 mounted on the substrate 11. A plurality of light emitting elements 12 are mounted on the substrate 11, but the number of light emitting elements 12 may be one, and is not particularly limited.

[0020] The substrate 11 is a mounting substrate for mounting the light emitting element 12. Although not shown, the substrate 11 is provided with metal wiring electrically connected to the light emitting element 12. The substrate 11 is, for example, a flat substrate having a circular shape in a plan view.

[0021] The substrate 11 may be, for example, a resin substrate made of a resin material, a metal-based substrate obtained by applying an insulating coating to a base material made of a metal material such as aluminum or copper, or a ceramic substrate which is a sintered body of a ceramic material such as alumina. Although the substrate 11 is a rigid substrate, it may also be a flexible substrate.

[0022] The light-emitting elements 12 are an example of a light source that emits light. In this embodiment, the light-emitting elements 12 are white light sources that emit white light. Specifically, the light-emitting elements 12 are surface-mounted (SMD: Surface Mount Device) light-emitting elements.

[0023] For example, the light emitting element 12 is an SMD type LED element in which an LED chip is packaged. The SMD type LED element has a case (package), an LED chip mounted in the case, and a sealing member that seals the LED chip.

[0024] The LED chip is an example of a semiconductor light-emitting device that emits light using a predetermined DC power, and is a bare chip that emits monochromatic visible light. The LED chip is, for example, a blue LED chip that emits blue light when powered.

[0025] The sealing member is a translucent insulating resin material such as silicone resin. The sealing member in this embodiment contains a phosphor as a wavelength conversion material that converts the wavelength of light from the LED chip. In other words, the sealing member is a phosphor-containing resin in which a phosphor is contained in a translucent resin, and wavelength-converts (color-converts) the light from the LED chip to a predetermined wavelength. The sealing member is filled into the recess of the container.

[0026] For example, if the LED chip is a blue LED chip, a phosphor-containing resin in which YAG (yttrium aluminum garnet) yellow phosphor particles are dispersed in silicone resin can be used as the sealing material to obtain white light. As a result, the yellow phosphor particles are excited by the blue light from the blue LED chip and emit yellow light, and the sealing material emits white light as a composite light of the yellow light from the yellow phosphor particles and the blue light from the blue LED chip. Note that the sealing material may also contain light diffusing materials such as silica and fillers dispersed therein.

[0027] The plurality of light-emitting elements 12 may include light-emitting elements that emit light of different color temperatures. For example, the plurality of light-emitting elements 12 may include light-emitting elements with a high color temperature (e.g., 6500 K) and light-emitting elements with a low color temperature (e.g., 2700 K). Color adjustment is possible by adjusting the on / off and light emission intensity of each light-emitting element or each group of color temperatures.

[0028] 3, the light source unit 10 is housed in a first cylindrical portion 51 of the housing 50. Specifically, the light source unit 10 is disposed on and fixed to the main surface of a module plate 15 disposed in the first cylindrical portion 51 (space 51c).

[0029] The module plate 15 is a support base that supports the light source section 10. On the module plate 15, the substrate 11 of the light source section 10 is placed.

[0030] The module plate 15 also functions as a heat sink that dissipates heat generated by the light source unit 10. Therefore, the module plate 15 is preferably made of a metal material such as aluminum or a resin material with high thermal conductivity. In this embodiment, the module plate 15 is made of metal, for example, a metal plate made of aluminum.

[0031] 3, the insulating plate 70 is disposed between the module plate 15 and the power supply unit 20. Specifically, the insulating plate 70 is disposed between the module plate 15 and the circuit board 21 of the power supply unit 20.

[0032] The insulating plate 70 is made of an insulating material. For example, the insulating plate 70 is an insulating sheet made of an insulating resin material such as silicone or acrylic. The insulating plate 70 may be either a rigid plate or a flexible plate. In this embodiment, the insulating plate 70 is an insulating heat-conductive sheet having rubber elasticity made of an elastomer such as silicone with high thermal conductivity.

[0033] The light source unit 10, the module plate 15, and the insulating plate 70 are fixed to one another with screws. Specifically, the light source unit 10, the module plate 15, and the insulating plate 70 can be fixed together by screwing the substrate 11 of the light source unit 10 to the insulating plate 70 with the module plate 15 sandwiched between them. Note that the light source unit 10, the module plate 15, and the insulating plate 70 do not necessarily have to be fixed together by screws, and they may also be fixed together with an adhesive.

[0034] The power supply unit 20 supplies power to the light source unit 10. Specifically, the power supply unit 20 generates power for causing the light source unit 10 to emit light. For example, the power supply unit 20 converts AC power (e.g., power from a commercial AC power source of 100 V) supplied from the pair of conductive pins 80 into DC power, and supplies the DC power to the light source unit 10. The power supply unit 20 also generates power for operating the control unit 30, and supplies the generated power to the control unit 30.

[0035] 3, the power supply unit 20 includes a circuit board 21 and circuit components 22 mounted on the circuit board 21. The circuit board 21 has a plurality of circuit components 22 mounted thereon.

[0036] Circuit board 21 is an example of a first substrate, and is, for example, a printed circuit board (PCB) on which metal wiring such as copper foil is patterned. In this embodiment, circuit board 21 is, for example, a plate-like board having a substantially circular shape in a plan view. Note that the shape of circuit board 21 in a plan view is not limited to this, and may be a polygonal shape such as a rectangle.

[0037] The multiple circuit components 22 are, for example, capacitive elements such as electrolytic capacitors or ceramic capacitors, coil elements (inductors) such as choke coils or choke transformers, transistor elements such as FETs (Field Effect Transistors), resistive elements such as resistors, or diodes.

[0038] The plurality of circuit components 22 include, for example, at least one of surface-mount components, which are surface-mount type circuit components, and lead components, which are leaded type circuit components having an element body and a pair of leads drawn out from the element body. The main circuit components 22 are arranged on the main surface of the circuit board 21 opposite to the light source unit 10.

[0039] In the present embodiment, the power supply unit 20 is disposed between the light source unit 10 and the control unit 30. Specifically, the power supply unit 20 is housed in the first cylindrical portion 51 of the housing 50. For example, the power supply unit 20 is held by a circuit holder disposed in the housing 50.

[0040] The control unit 30 controls the power supply unit 20. Specifically, the control unit 30 controls the amount of power supplied from the power supply unit 20 to the light source unit 10, thereby controlling the turning on and off of the light source unit 10 and the dimming and color adjustment of the light source unit 10.

[0041] 3, the control unit 30 includes a substrate 31 and an integrated circuit element 32 mounted on the substrate 31. Note that circuit components other than the integrated circuit element 32 may also be mounted on the substrate 31.

[0042] The substrate 31 is an example of a second substrate, and is, for example, a printed circuit board (PCB) on which metal wiring such as copper foil is patterned. In the present embodiment, the substrate 31 is, for example, a plate-like substrate having a substantially circular shape in a plan view. The substrate 31 is smaller than the circuit board 21 of the power supply unit 20 in a plan view. The substrate 31 is sized so as to be able to be housed in the second cylindrical portion 52 of the housing 50.

[0043] The integrated circuit element 32 is, for example, a microcontroller. The microcontroller includes, for example, a non-volatile memory in which a program is stored, a volatile memory that is a temporary storage area for executing the program, an input / output port, a processor that executes the program, etc. The integrated circuit element 32 may be a programmable FPGA (Field Programmable Gate Array) or a reconfigurable processor.

[0044] The integrated circuit element 32 performs main processing for controlling the power supply unit 20. Specifically, the integrated circuit element 32 performs processing such as adjusting the power supplied from the power supply unit 20 for turning on and off the light source unit 10 and adjusting the brightness and color.

[0045] The integrated circuit element 32 may also include a signal processing circuit that processes wireless signals (radio waves) received by the antenna. For example, the wireless signals include information for issuing various instructions such as turning on and off the light source unit 10 and adjusting the brightness and color. Wireless communication via the antenna is performed based on wireless communication standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), or ZigBee (registered trademark).

[0046] The antenna is, for example, patterned on the substrate 31. Alternatively, the antenna may be disposed between the module plate 15 and the light-transmitting cover 90 in order to improve reception sensitivity.

[0047] The integrated circuit element 32 is disposed on the main surface of the substrate 31 opposite to the circuit board 21. That is, the integrated circuit element 32 is disposed between the substrate 31 and the bottom 52a of the second cylindrical portion 52. The integrated circuit element 32 may also be disposed on the main surface of the substrate 31 facing the circuit board 21.

[0048] The control unit 30 is housed in the second cylindrical portion 52 of the housing 50. Specifically, the board 31 of the control unit 30 is supported on the circuit board 21 of the power supply unit 20 via the connector 40. The board 31 overlaps the circuit board 21 in a plan view. Note that the plan view refers to a view perpendicular to the main surface of the board 31. In this embodiment, the board 31 is disposed parallel to the circuit board 21. By supporting the board 31, it is possible to dispose the control unit 30 inside the second cylindrical portion 52.

[0049] In this embodiment, the control unit 30 has a plurality of operation modes, which are switched by the operation switch 60. Specific examples of the operation modes will be described later.

[0050] The connector 40 electrically connects the power supply unit 20 and the control unit 30. The connector 40 also supports the control unit 30. The connector 40 is, for example, a pin header, and has conductive metal pins 41 and a resin member 42 that covers part of the metal pins 41. The resin member 42 supports the circuit board 21 of the power supply unit 20 and the board 31 of the control unit 30 by having both ends of the resin member 42 abut against the circuit board 21 of the power supply unit 20 and the board 31 of the control unit 30.

[0051] The electrical connection between the power supply unit 20 and the control unit 30 and the support of the control unit 30 may be achieved by different members. For example, instead of the connector 40, a lead wire may be provided to electrically connect the power supply unit 20 and the control unit 30. Also, a dedicated member may be provided to support the control unit 30. Alternatively, the control unit 30 may be held by a circuit holder or a housing 50.

[0052] The housing 50 accommodates the light source unit 10, the power supply unit 20, and the control unit 30. As shown in FIGS. 1 to 3, the housing 50 includes a first cylindrical portion 51 and a second cylindrical portion 52. The second cylindrical portion 52 is smaller than the first cylindrical portion 51 and is provided so as to protrude outward (opposite the light emission direction) from a bottom portion 51a of the first cylindrical portion 51. For this reason, a step is provided on the outer surface of the housing 50 at the connection portion between the first cylindrical portion 51 and the second cylindrical portion 52.

[0053] The first cylindrical portion 51 is located closer to the light emission side than the second cylindrical portion 52. The first cylindrical portion 51 forms a space 51c that accommodates the light source portion 10 and the power supply portion 20. That is, the light source portion 10 and the power supply portion 20 are accommodated inside the first cylindrical portion 51 (space 51c).

[0054] The first cylindrical portion 51 has an annular bottom portion 51a and a side wall 51b. The bottom portion 51a has a circular ring shape (doughnut shape) of a predetermined width in a plan view. A conductive pin 80 is inserted into and fixed to the bottom portion 51a. The side wall 51b is annularly provided along the outer periphery of the bottom portion 51a and stands on the outer periphery of the bottom portion 51a. In a plan view, the outer diameter of the side wall 51b corresponds to the outer diameter of the housing 50. The light source unit 10 and the power supply unit 20 are arranged in a space 51c surrounded by the side wall 51b. The power supply unit 20 is arranged closer to the bottom 51a than the light source unit 10.

[0055] The second cylindrical portion 52 is connected to the inner periphery of the annular bottom portion 51a of the first cylindrical portion 51. The second cylindrical portion 52 is provided on the outside of the first cylindrical portion 51. That is, the second cylindrical portion 52 is located on the opposite side from the light emission side of the first cylindrical portion 51. The second cylindrical portion 52 forms a space 52c that houses the control unit 30. That is, the control unit 30 is housed inside the second cylindrical portion 52 (space 52c).

[0056] The second cylindrical portion 52 has a bottom portion 52a and a side wall 52b. The bottom portion 52a has a substantially circular shape in a plan view. The side wall 52b is annularly provided so as to connect the inner periphery of the annular bottom portion 51a with the outer periphery of the bottom portion 52a. In a plan view, the outer diameter of the side wall 52b is shorter than the outer diameter of the side wall 51b. Also, for example, the height of the side wall 52b is shorter than the height of the side wall 51b. The control unit 30 is disposed in a space 52c surrounded by the side wall 52b.

[0057] The first cylindrical portion 51 and the second cylindrical portion 52 are integrally formed using the same material. For example, the housing 50 is made of a resin material such as polybutylene terephthalate (PBT) or a metal material such as aluminum.

[0058] The operation switch 60 is an operation switch for switching the operation mode of the control unit 30. The operation switch 60 is provided on the outer surface of the housing 50. This allows a person to operate the operation switch 60 from outside.

[0059] In this embodiment, the operation switch 60 is provided on the bottom 52a of the housing 50. Specifically, the operation switch 60 is provided by hollowing out a portion of the circular bottom 52a and a portion of the side wall 52b. In a plan view of the bottom 52a, the operation switch 60 is provided so as not to protrude from the smallest circumscribing circle relative to the outer shape of the bottom 52a. In addition, in a side view, the operation switch 60 is provided so as not to protrude beyond the outer surface of the bottom 52a (the main surface opposite to the light emission direction). This prevents the operation switch 60 from interfering with the installation of the lighting device 1 to a lighting fixture. Note that, as long as it does not interfere with installation, the operation switch 60 may protrude from the smallest circumscribing circle relative to the outer shape of the bottom 52a or may protrude beyond the outer surface of the bottom 52a.

[0060] The operation switch 60 is electrically connected to the control unit 30. For example, the operation switch 60 is mounted on the main surface of the substrate 31. The operation switch 60 is electrically connected to the integrated circuit element 32 via metal wiring provided on the surface of the substrate 31. The integrated circuit element 32 switches and sets the operation mode based on the result of operating the operation switch 60. Note that the operation switch 60 may be mounted on a dedicated substrate different from the substrate 31.

[0061] The operation switch 60 is, for example, a dial switch. A person can select and set a predetermined operation mode by rotating the operation switch 60. In the example shown in FIG. 2, the operation switch 60 can switch between six operation modes, "1" to "6." The numbers "1" to "6" are identification information for identifying the operation mode, and are marked on the surface of the operation switch 60 so that they can be seen by a person.

[0062] In this way, the operation switch 60 is provided with identification information for identifying the operation mode. In the example shown in FIG. 2, the identification information is a number, but it may also be alphabets, kana characters, symbols, or the like. An icon representing the characteristics of the operation mode may also be provided as the identification information. Alternatively, text representing the operation mode may also be provided as the identification information. By providing the icon or text, the user can easily visually check the operation mode being set.

[0063] Note that when numbers or letters are attached as identification information, an explanation of the operation mode (for example, text indicating the name of the operation mode) may be attached to the surface of the housing 50. Even if there is no space to attach a detailed explanation to the operation switch 60, the surface of the housing 50 can be used to make the operation mode easier for the user to understand. In particular, the surfaces of the bottom 51a or 52a or the side wall 52b of the housing 50 cannot be visually confirmed when the lighting device 1 is attached to a lighting fixture. Therefore, even if text or the like is attached to these surfaces, the design of the appearance and lighting state of the lighting device 1 is not impaired.

[0064] The conductive pins 80 protrude outside the housing 50. Specifically, the conductive pins 80 protrude from the bottom 51a of the first cylindrical portion 51 of the housing 50. In this embodiment, a pair (two) of conductive pins 80 is provided. The pair of conductive pins 80 has a Gx53 base structure. The pair of conductive pins 80 is inserted into and fixed in a power supply socket of a lighting fixture. Specifically, after the pair of conductive pins 80 are inserted into the power supply socket, the housing 50 is rotated horizontally about its center as an axis, whereby the pair of conductive pins 80 engage and are fixed in the power supply socket. By fixing the pair of conductive pins 80 to the power supply socket, AC power is supplied from the power supply socket to the pair of conductive pins 80. Furthermore, by holding the pair of conductive pins 80 in the power supply socket, the lighting device 1 is attached and held in the lighting fixture.

[0065] The conductive pin 80 is electrically connected to the power supply unit 20 via a conductive wire 81. Specifically, the conductive wire 81 is wound around an end of the conductive pin 80, and the conductive pin 80 and the circuit board 21 are connected by this conductive wire 81. Specifically, one end of the conductive wire 81 is wound around the conductive pin 80 and soldered, and the other end of the conductive wire 81 is soldered to the circuit board 21. The conductive wire 81 may be, for example, a lead wire. By connecting the conductive pin 80 and the circuit board 21 with the conductive wire 81 in this manner, the AC voltage received by the pair of conductive pins 80 is supplied to the power supply unit 20 via the conductive wire 81. One end of the conductive pin 80 is exposed to the outside of the housing 50 and is connected to a power supply socket of the lighting fixture.

[0066] The light-transmitting cover 90 is a light-transmitting member having light-transmitting properties. Therefore, light incident on the inner surface of the light-transmitting cover 90 passes through the light-transmitting cover 90 and is extracted to the outside of the light-transmitting cover 90. As shown in FIG. 3 , the light-transmitting cover 90 is attached to the housing 50 so as to cover the light source unit 10. Specifically, the light-transmitting cover 90 is attached to the open end of the first cylindrical portion 51 of the housing 50.

[0067] The light-transmitting cover 90 may be made of a light-transmitting resin material such as acrylic or polycarbonate, or a glass material such as silica glass. In the present embodiment, the light-transmitting cover 90 is made of a light-transmitting resin material.

[0068] The light-transmitting cover 90 may be a transparent cover that does not have light diffusion properties, or may be a diffusion cover that has light diffusion properties (light scattering properties). In this embodiment, the light-transmitting cover 90 is a milky-white diffusion cover that has light diffusion properties. For example, the light-transmitting cover 90 can be imparted with light diffusion properties by forming a light diffusion film (light diffusion layer) on the inner or outer surface of the light-transmitting cover 90. As an example, a milky-white light diffusion film can be formed on the light-transmitting cover 90 by applying a resin containing a light diffusion material such as silica or calcium carbonate, or a white pigment, to the entire inner or outer surface of the transparent light-transmitting cover 90. Alternatively, the light-transmitting cover 90 itself may be a milky-white light-transmitting cover made of a resin in which a light diffusion material such as silica or calcium carbonate is dispersed. In this way, by imparting light diffusion properties to the light-transmitting cover 90, light incident on the light-transmitting cover 90 from the light source unit 10 can be diffused, thereby widening the light distribution angle.

[0069] The light-transmitting cover 90 may be a lens that converges or diverges light. For example, a Fresnel lens may be used as the light-transmitting cover 90.

[0070] [Operation mode] Next, the operation modes of the control unit 30 will be described.

[0071] In the lighting device 1 according to the present embodiment, the control unit 30 has a plurality of operation modes. Specifically, the plurality of operation modes include a normal mode and a registration mode. The normal mode is an operation mode in which the light source unit 10 can be turned on and off. If the light source unit 10 is capable of dimming and color adjustment, the plurality of operation modes may include a dimming mode in which only dimming is possible, a color adjustment mode in which only color adjustment is possible, and a dimming and color adjustment mode in which both dimming and color adjustment are possible.

[0072] The registration mode is an operation mode for registering the lighting device 1. Specifically, in the registration mode, registration is performed for communication with the control unit 30. The registration for communication includes, for example, associating an address with the lighting device 1, and pairing the lighting device 1 with a gateway, a router, a smartphone, or a dedicated operation terminal.

[0073] Such registration must be performed while power is being supplied to the lighting device 1. The user operates the operation switch 60 to switch to registration mode, and then attaches the lighting device 1 to the lighting fixture. When registration is completed on a terminal such as a router, the lighting device 1 has a function to notify that registration is complete by lighting up or making a sound. After registration is complete, the user removes the lighting device 1 from the lighting fixture and operates the operation switch 60 to switch to normal mode, dimming / color adjustment mode, etc. Then, the user attaches the lighting device 1 to the lighting fixture. This makes it possible to turn the lighting device 1 on and off (as well as dim and adjust the color) using a smartphone or a dedicated operation terminal.

[0074] In this way, the operation mode can be switched using the physical operation switch 60, so that the user can easily set the operation mode in an easy-to-understand manner.

[0075] The multiple operation modes switchable by the operation switch 60 may include, for example, a scene setting mode for setting one or more lighting scenes, and a scene lighting mode for lighting the light in the set lighting scene. A lighting scene represents a lighting state of a space suited to a predetermined purpose (e.g., concentration, relaxation, etc.), and is formed by only the lighting device 1 or by multiple lighting devices including the lighting device 1.

[0076] Alternatively, the multiple operation modes switchable by the operation switch 60 may include a mode for performing a function other than lighting. For example, the lighting device 1 may include a sound output device such as a speaker, and the multiple operation modes may include a mode for permitting sound output and a mode for prohibiting sound output. Alternatively, the lighting device 1 may include a detection device such as a camera or an infrared sensor, and the multiple operation modes may include a mode for performing a detection function and a mode for stopping the detection function.

[0077] [Variations] Next, a modified example of the above-described embodiment will be described. In the following description, differences from the embodiment will be mainly described, and explanation of commonalities will be omitted or simplified.

[0078] FIG. 4 is a perspective view of a lighting device 2 according to Modification 1. In the lighting device 2 shown in FIG. 4, an operation switch 60 is provided on the bottom 51a of the first cylindrical portion 51. Specifically, the operation switch 60 is provided by hollowing out a portion of the annular bottom 51a and a portion of the side wall 51b. In a plan view of the bottom 51a, the operation switch 60 is provided so as not to protrude from the smallest circumscribed circle relative to the outline of the bottom 51a. Specifically, when viewed from the light emission side of the lighting device 2 (i.e., the front side of the translucent cover 90), the operation switch 60 does not protrude from the side wall 51b of the first cylindrical portion 51. In a side view, the operation switch 60 is provided so as not to protrude beyond the outer surface of the bottom 51a (the main surface opposite to the light emission direction). This prevents the operation switch 60 from interfering with the installation of the lighting device 2 to a lighting fixture. As long as it does not interfere with installation, the operation switch 60 may protrude from the smallest circumscribing circle relative to the outer shape of the bottom 51a, or may protrude from the outer surface of the bottom 51a.

[0079] In this modification, the operation switch 60 is mounted on, for example, the circuit board 21 of the power supply unit 20. The operation switch 60 is electrically connected to the integrated circuit element 32 via the circuit board 21, the connector 40, and the board 31. The operation switch 60 may be mounted on a dedicated board different from the circuit board 21.

[0080] FIG. 5 is a perspective view of a lighting device 3 according to Modification 2. The lighting device 3 shown in FIG. 5 includes an operation switch 61 instead of the operation switch 60. The operation switch 61 is a DIP (Dual In-line Package) switch. The operation switch 61 has multiple levers that can be switched on / off. For example, one operation mode is associated with each lever, but this is not limiting. An operation mode may be set by combining the on / off states of multiple levers. In the example shown in FIG. 5, six levers are provided, so a maximum of 32 (=2 6 ) operating modes can be set.

[0081] In this modification, the operation switch 61 may be provided on the bottom portion 51a, similarly to the first modification.

[0082] [Effects, etc.] As described above, the lighting device 1 according to this embodiment includes a light source unit 10, a power supply unit 20 that supplies power to the light source unit 10, a control unit 30 that controls the power supply unit 20, a housing 50 that houses the light source unit 10, the power supply unit 20, and the control unit 30, a conductive pin 80 electrically connected to the power supply unit 20, and an operation switch 60 for switching the operation mode of the control unit 30. The housing 50 includes a first cylindrical portion 51 having an annular bottom portion 51a and a second cylindrical portion 52 that is connected to the inner periphery of the bottom portion 51a and is provided outside the first cylindrical portion 51. The conductive pin 80 protrudes from the bottom portion 51a. The operation switch 60 or 61 is provided on the outer surface of the housing 50. The power supply unit 20 includes a circuit board 21 and a circuit component 22 mounted on the circuit board 21. The control unit 30 includes a substrate 31 and an integrated circuit element 32 mounted on the substrate 31. The substrate 31 overlaps the circuit board 21 in a plan view.

[0083] This allows the user to switch between operation modes using the operation switch 60 or 61 that can be operated by the user, so that the operation mode can be set in an easy and understandable manner for the user.

[0084] Furthermore, the power supply unit 20 and the control unit 30 are arranged in a two-story structure (a structure in which the circuit board 21 and the board 31 are arranged on top of each other with a space between them) within the housing 50. The integrated circuit element 32 is more susceptible to malfunctions and failures caused by heat than the circuit components 22, etc. Therefore, by separating the integrated circuit element 32 from the light source unit 10, the effect of heat generated by the light source unit 10 on the integrated circuit element 32 can be suppressed.

[0085] The location of the operation switch 60 or 61 can be determined based on, for example, the positional relationship with the control unit 30 housed in the housing 50. By arranging the control unit 30 and the operation switch 60 or 61 close to each other, electrical connection between the operation switch 60 or 61 and the control unit 30 can be easily established.

[0086] Further, for example, the second cylindrical portion 52 has a bottom portion 52a, and the operation switch 60 or 61 is provided on the bottom portion 52a.

[0087] This arrangement prevents the operation switch 60 or 61 from being seen from the light output side, thereby preventing the appearance and lighting state of the lighting device 1 from being impaired after installation in a lighting fixture. Furthermore, the operation switch 60 or 61 and the control unit 30 can be placed close to each other, facilitating electrical connection.

[0088] Also, for example, the operation switch 60 or 61 may be provided on the bottom portion 51a.

[0089] This arrangement prevents the operation switch 60 or 61 from being seen from the light output side, thereby preventing the design of the appearance and lighting state of the lighting device 1 after it has been attached to a lighting fixture from being impaired.

[0090] Moreover, for example, the operation switch 60 or 61 is a dial switch or a DIP (Dual In-line Package) switch.

[0091] This allows the operation switch 60 or 61 to be realized as an intuitive and easy-to-understand switch.

[0092] Furthermore, for example, the control unit 30 is housed in the second cylindrical portion 52.

[0093] This allows the operation switch 60 or 61 and the control unit 30 to be disposed close to each other. For example, the operation switch 60 or 61 can be mounted on the substrate 31 of the control unit 30, which facilitates electrical connection between the operation switch 60 or 61 and the control unit 30. Since no dedicated lead wire or connector is required for connecting the operation switch 60 or 61 and the control unit 30, the lighting device 1 can be easily assembled and made lighter.

[0094] Furthermore, the control unit 30 can be placed away from the light source unit 10. This reduces the effect of heat generated by the light source unit 10 when it emits light on the control unit 30. This reduces malfunction or failure of the control unit 30 due to heat.

[0095] Furthermore, for example, the control unit 30 includes a signal processing circuit that processes a radio signal received by an antenna.

[0096] This allows the operation switch 60 or 61 to be used to switch to a registration mode for registering wireless communication. Also, since microcontrollers, which are often used as signal processing circuits, are sensitive to heat, it is more useful to have a configuration in which they can be placed away from the light source unit 10.

[0097] (others) Although the lighting device according to the present invention has been described based on the above embodiment, the present invention is not limited to the above embodiment.

[0098] For example, the lighting device 1 may include a plurality of operation switches 60 or 61. This increases the number of switchable operation modes.

[0099] The operation switch 60 may also be a push button switch or a toggle switch.

[0100] Furthermore, for example, the light emitting element 12 may be an LED chip directly mounted on the substrate 11. That is, the light source unit 10 may be a COB type light emitting module.

[0101] Furthermore, for example, the light source unit 10 has been described as including an LED as the light emitting element 12, but the present invention is not limited to this. The light emitting element 12 may be a laser element or an organic EL (Electroluminescence) element.

[0102] Furthermore, for example, at least a part or the whole of the power supply unit 20 may be housed within the second cylindrical portion 52. For example, the circuit board 21 of the power supply unit 20 and the board 31 of the control unit 30 may be arranged side by side without overlapping each other in a plan view.

[0103] Furthermore, for example, the power supply unit 20 and the control unit 30 may have a common substrate. For example, a plurality of circuit components 22 and an integrated circuit element 32 may be mounted on the circuit board .

[0104] Furthermore, for example, the control unit 30 may control the power supply unit 20 based on information acquired via an infrared detection element that detects infrared rays. The infrared detection element is, for example, a photoelectric conversion element that is sensitive in the infrared band. The infrared detection element is, for example, arranged closer to the light source unit 10 than the module plate 15.

[0105] In addition, the present invention also includes forms obtained by applying various modifications to each embodiment that a person skilled in the art would think of, and forms realized by arbitrarily combining the components and functions of each embodiment within the scope of the present invention.
