For example, a resin material such as acrylic (PMMA) or polycarbonate (PC) is used. It is configured. The translucent cover 110 may have a transparent structure without light diffusibility or a diffusion structure with light diffusibility. For example, a milky white light diffusing film may be formed by applying a resin or white pigment containing a light diffusing material such as silica or calcium carbonate on the inner surface of the translucent cover 110, or fine irregularities may be formed on the translucent cover 110. The translucent cover 110 having a light diffusion function can be configured.

  In addition, the translucent cover 110 is fixed to the housing 120 so as to close the first opening 120 a in order to protect the LED module 140 and the circuit board 160 disposed inside the housing 120.

  The support stand 130 is a support member that supports the circuit board 160 and the housing 120. The support stand 130 also functions as a heat sink that dissipates heat generated by the LED module 140. Therefore, the support base 130 is preferably composed of a metal material such as aluminum or a resin material having high thermal conductivity. As illustrated in FIG. 2B, the support base 130 is disposed so as to close the second opening 120 b of the housing 120.

The support base 130 functions as a predetermined base connected to the lighting fixture together with the housing 120 and the connection pins 180. The LED unit 100 has a standardized base structure that fits into a socket of a lighting fixture. Examples of such a base structure include a GX53 base and a GH76p base as described above.

  The translucent cover 110, the casing 120, and the support stand 130 correspond to the main body. That is, the main body portion has a light emitting surface for extracting light from the light emitting portion 142 (a surface on the light irradiation side including the translucent cover 110), a side surface provided around the light emitting surface, and a side opposite to the light emitting surface. It has an installation surface (a surface on the side attached to the lighting fixture, including the support base 130), and stores a control unit and a light emitting unit 142, which will be described later.

  The LED module 140 is a light source in the LED unit 100 and emits light of a predetermined color (wavelength) such as white. The LED module 140 (substrate 141) is placed on the support base 130 and fixed to the support base 130. For example, the LED module 140 and the support base 130 can be fixed by applying an adhesive between the substrate 141 and the support base 130.

  The LED module 140 emits light by electric power supplied from the circuit board 160. The light emitted from the LED module 140 passes through the translucent cover 110 and is emitted outside the lamp.

  As illustrated in FIG. 2B, the LED module 140 can be configured by, for example, a substrate 141 and a light emitting unit 142.

  The LED module 140 has a so-called COB (Chip On Board) structure in which bare chips (LEDs, light emitting elements) are directly mounted on the substrate 141.

  The light emitting unit 142 includes a plurality of LEDs and a sealing member that seals the plurality of LEDs. The LED is an example of a light emitting element, and is a semiconductor light emitting element that emits light with a predetermined power. The LED in the first embodiment is a bare chip that emits monochromatic visible light. For example, a blue light emitting LED chip that emits blue light when energized can be used. For example, a plurality of LEDs are mounted in a plurality of rows or a matrix on the main surface of the substrate 141.

  The sealing member is made of, for example, resin and is formed so as to collectively seal a plurality of LEDs. In this case, the sealing member may be formed linearly so as to be collectively sealed for each LED element row, or the shape in plan view is circular so that all the LEDs on the substrate 141 are collectively sealed. You may form in a shape or a rectangular shape.

  The sealing member is mainly made of a translucent material, but when it is necessary to convert the wavelength of the LED light to a predetermined wavelength, a wavelength conversion material is mixed into the translucent material. The sealing member in Embodiment 1 is a wavelength conversion member that includes a phosphor as a wavelength conversion material and converts the wavelength (color) of light emitted from the LED. Such a sealing member can be constituted by, for example, an insulating resin material (phosphor-containing resin) containing phosphor particles as a phosphor. The phosphor particles are excited by light emitted from the LED and emit light of a desired color (wavelength).

  As a translucent resin material constituting the sealing member, for example, a silicone resin can be used. Further, as the phosphor particles to be included in the sealing member, for example, when the LED is a blue light emitting LED that emits blue light, for example, YAG-based yellow phosphor particles can be used to obtain white light. . Thereby, a part of blue light emitted from the LED is wavelength-converted into yellow light by the yellow phosphor particles contained in the sealing member. Then, the blue light that has not been absorbed by the yellow phosphor particles and the yellow light that has been wavelength-converted by the yellow phosphor particles are mixed and emitted from the sealing member as white light.

  As the substrate 141, a ceramic substrate, a resin substrate, or a metal base substrate can be used. As the shape of the substrate 141, a rectangular shape in plan view can be used, but a polygonal shape such as a hexagonal shape or an octagonal shape or a circular shape may also be used.

The reflecting plate 150 is a reflecting member having a reflecting function, and includes an incident port that is an opening through which light from the LED module 140 is incident and an emitting port that is an opening through which light incident from the incident port is emitted from the reflecting plate 150. Have. Reflector 150 in Embodiment 1 has a truncated cone shape that is configured such that the inner diameter gradually increases from the entrance to the exit. Specifically, the reflecting plate 150 has a trumpet shape (funnel shape).

  The entrance is configured to surround the light emitting region (light emitting unit 142) of the LED module 140. Further, the opening area of the emission port is substantially the same as the area of the flat portion of the translucent cover 110.

  The inner surface of the reflecting plate 150 is a reflecting surface that reflects light from the LED module 140. The reflection surface is configured to reflect the light incident from the incident port and output the light from the output port. The light from the LED module 140 is guided to the translucent cover 110 by the reflector 150.

  The reflector 150 can be made of, for example, a hard white resin material having insulation properties. In order to improve the reflectance, the reflection surface may be configured by coating the inner surface of the resin-made reflection plate 150 with a metal vapor deposition film (metal reflection film) made of a metal material such as silver or aluminum. Absent. Moreover, you may shape | mold the reflecting plate 150 whole using metal materials, such as aluminum, without using a resin material.

  The circuit board 160 is a printed board on which metal wiring is patterned. As shown in FIG. 2B, the circuit board 160 in the first embodiment is an annular (doughnut-shaped) board in which a circular opening is formed. It is arranged outside. For example, the circuit board 160 is held by the casing 120 by screwing the circuit board 160 and the casing 120 together.

  A driving circuit (not shown) for causing the LED module 140 (light emitting unit 142) to emit light is provided on the main surface of the circuit board 160 on the light irradiation side. For example, the drive circuit converts AC power (for example, power from an AC 100 V commercial power source) supplied from the connection pin 180 into DC power, and supplies the DC power to the LED module 140. The power supplied to the drive circuit (circuit board 160) may be direct current power instead of alternating current power.

  Examples of circuit elements (not shown) constituting the drive circuit include capacitive elements such as electrolytic capacitors and ceramic capacitors, resistance elements, coil elements, choke coils (choke transformers), noise filters, diodes, and integrated circuit elements. A semiconductor element or the like. Many circuit elements are mounted on the main surface of the circuit board 160 on the light irradiation side.

  The first connection unit 190 is a USB (Universal Serial Bus) compliant connector, an HDMI (registered trademark) (High Definition Multimedia Interface) compliant connector, or a S-ATA (Serial Advanced Technology standardized connector connector). There may be a dedicated connector. That is, the first connection unit 190 is detachably connected to the second connection unit 210 of the function adding device 200 and can be transmitted in any shape as long as the control signal can be transmitted from the function adding device 200 to the LED unit 100. There may be.

  The heat conductive sheet 170 is a sheet for releasing heat from the LED module 140 transmitted through the support base 130 to the lighting fixture side. Specifically, the heat conductive sheet 170 is a resin sheet having a high thermal conductivity, and for example, a silicon sheet or an acrylic sheet can be used.

  The connection pin 180 (third connection portion, cap pin) is a conductive pin and has a function of receiving power for causing the LED module 140 to emit light from the outside of the lamp. That is, the connection pin 180 is an electrical connection pin for supplying power.

  For example, the pair of connection pins 180 receives predetermined AC power from the lighting fixture. Each connection pin 180 and circuit board 160 are connected by a lead wire (not shown), and the AC voltage received by the pair of connection pins 180 is supplied to the circuit board 160 (drive circuit) via the lead wire. The The pair of connection pins 180 receive AC voltage, but may be configured to receive two different DC voltages.

  Moreover, the connection pin 180 functions also as an attachment part for attaching the LED unit 100 to a lighting fixture. Specifically, the LED unit 100 is held by the lighting fixture by connecting the connection pin 180 to the socket of the lighting fixture.

  The connection pin 180 is configured to protrude outward from the surface opposite to the light irradiation side surface of the housing 120. For example, the connection pin 180 is press-fitted and fixed in a through hole provided in the housing 120.

  Two connection pins 180 are provided for power supply, but in addition to connection pins for power supply, electrical connection pins for signals for receiving electrical signals such as dimming signals, or others A connection pin having the above functions may be provided.

  Next, functional configurations and the like of the LED unit 100 and the function addition device 200 according to Embodiment 1 will be described with reference to FIGS. 3 and 4. FIG. 3 is a functional block diagram of the LED unit 100 and the function adding device 200 according to the first embodiment. FIG. 4 is a cross-sectional view of an illumination device including LED unit 100 according to Embodiment 1.

  First, the LED unit 100 will be described.

  As shown in FIG. 3, the LED unit 100 includes a light emitting unit 142, a power conversion unit 191, a first connection unit 190, and a control unit 192. The control unit 192 includes a power supply unit 193 and a power supply unit 194.

  The light emitting unit 142 is a light emitting unit that emits light using DC power supplied from the power supply unit 194 of the control unit 192.

  The power conversion unit 191 converts AC power supplied from the lighting fixture 300 into DC power and outputs the DC power to the control unit 192. Here, the LED unit 100 is attached to the lighting fixture 300 (the reflecting plate 310 and the socket 320) provided on the ceiling of the room as shown in FIG. The power conversion unit 191 receives power from the lighting fixture 300 through the connection pin 180 when the connection pin 180 is inserted into the connection hole 321 (fourth connection portion) of the lighting fixture 300.

  Specifically, the power conversion unit 191 is, for example, a bridge-type full-wave rectifier circuit including four diodes included in the above-described drive circuit, but in any form such as an AC-DC converter IC. There may be.

  The power supply unit 193 operates the control unit 192 using the DC power received from the power supply conversion unit 191. Specifically, the power supply unit 193 is, for example, a power supply circuit included in the above-described drive circuit, but may be in any form such as a DC-DC converter IC.

  The power supply unit 194 supplies power to the light emitting unit 142. The power supply unit 194 is, for example, an inverter circuit included in the drive circuit and a rectifier circuit connected to the inverter circuit. However, the power supply unit 194 may be in any form such as a chopper control circuit that changes the switching control state according to the control signal and adjusts the power to the light emitting unit 142, for example. The chopper control circuit is specifically a PWM (Pulse Width Modulation) circuit, a PFM (Pulse Frequency Modulation) circuit, or the like. In a case where the control unit 192 controls only lighting and extinguishing of the light emitting unit 142, a switch that switches whether power is supplied to the light emitting unit 142 according to a control signal may be used.

  The control unit 192 controls the light emission of the light emitting unit 142 according to the control signal received from the function addition device 200 connected to the first connection unit 190. For example, the control unit 192 controls turning on and off of the light emitting unit 142 in accordance with the control signal. Specifically, the control unit 192 is a circuit that operates according to a control signal included in the above-described drive circuit, but may be realized as a function of an integrated circuit such as a processor, and in any manner. There may be.

  In Embodiment 1, the power supply unit 194 of the control unit 192 controls the light emission of the light emitting unit 142 by controlling the amount of power supplied to the light emitting unit 142 according to the control signal. In the first embodiment, specifically, the power supply unit 194 of the control unit 192 controls lighting and extinguishing of the light emitting unit 142 based on the control signal.

  Note that, as indicated by a broken line in FIG. 3, not the power supply unit 194 but the power supply unit 193 controls the amount of power received from the power supply conversion unit 191 or the power supplied to the power supply unit 194 according to the control signal. By doing so, the light emission of the light emitting unit 142 may be controlled. Specifically, when the power supply unit 194 is an IC that varies the output to the light emitting unit 142 according to the reference voltage supplied by the power source unit 193, the light emitting unit is adjusted by adjusting the input / output of the power source unit 193. The light emission of 142 can be controlled. When the power supply unit 193 controls only lighting and extinguishing of the light emitting unit 142, the power supply unit 193 may be a switch that switches the presence / absence of power to be received according to a control signal.

  The first connection unit 190 is a connector to which the second connection unit 210 of the function addition device 200 is detachably connected in order to receive a control signal from the sensor unit 250 of the function addition device 200. That is, the first connection unit 190 has a terminal for receiving a control signal from the sensor unit 250 of the function addition device 200. Further, the first connection unit 190 has a first terminal for supplying the DC power output from the power conversion unit 191 to the function addition device 200. The function adding device 200 operates by the electric power supplied through the first terminal.

  Next, the function addition device 200 will be described.

  As illustrated in FIG. 3, the function addition device 200 includes a second connection unit 210 and a sensor unit 250.

  The second connection portion 210 is a connector having a shape corresponding to the shape of the first connection portion 190 and is connected to the first connection portion 190. The function addition device 200 (sensor unit 250) operates with electric power supplied via the first terminal included in the first connection unit 190. The function adding device 200 may be configured to operate without receiving power supply from the LED unit 100 by incorporating a battery.

  The sensor unit 250 is a so-called human sensor module that detects infrared rays. The sensor unit 250 is not limited to a configuration that detects infrared rays. For example, the sensor unit 250 may detect illuminance, sound, temperature, and the like around the sensor unit 250. In this case, an existing illuminance sensor, sound sensor, temperature sensor, or the like can be applied to the sensor unit 250. Further, vibration of the sensor unit 250, user motion (user gesture), and the like may be detected. For example, when the LED unit 100 is provided in a moving body (such as a car), the sensor unit 250 detects vibration of the sensor unit 250 due to movement of the moving body. That is, the function addition device 200 may be a sensor device that detects a detection target.

  The detection of motion can be realized by applying a reflection type sensor (motion sensor) to the sensor unit 250, for example. When the sensor unit 250 is a reflective sensor, the sensor unit 250 projects light to the user and measures the distance to the user using the reflected light. That is, the sensor unit 250 can detect whether the user is within a determined distance. If the user puts his / her hand within the determined distance (detection range), the sensor unit 250 can detect this as a motion.
