Next, the speech recognition unit 721 collates the text of the recognized speech with wakeup words registered in the word table. For example, the speech recognition unit 721 checks whether or not the text of the recognized speech and the wakeup word are the same in appearance.
If the recognized speech text matches the wakeup word, i.e., if the wakeup word can be extracted from the speech text, the speech recognition unit 721 subsequently identifies the speech signal input from the microphone 75 as the user's instruction. . The speech contained in the speech signal identified as the user's instruction is converted into text, and the text is compared with a plurality of control words shown in the word table in the same manner as the wakeup words.
If the text of the recognized voice matches any one of a plurality of control words, that is, if the control word can be extracted from the text of the voice, the voice recognition unit 721 sends a control signal indicating the control word to the lighting control unit 425 of the power supply circuit 42. Output. In response to this, the lighting control section 425 instructs the lighting power generation section 423 on the duty ratio corresponding to the control signal.
The timer 723 measures the time that has passed since the speech recognition unit 721 extracted the wakeup word (hereinafter sometimes referred to as "elapsed time") in accordance with a command from the CPU.
Storage unit 725 includes a ROM. In addition to the word table described above, the storage unit 725 stores computer programs and the like for the speech recognition unit 721 to operate.

As shown in FIGS. 8 and 9, the voice recognition circuit 72 recognizes the voice of the power supply base 46 so that the end face of the voice board 74 abuts on the second protruding portion 465b of the audio board support positioning portion 465 of the power supply base 46. The through hole 74a of the audio board 74 is fitted into the second protruding portion 464b of the board support positioning portion 464. As shown in FIG. Along with this, the end of the audio board 74 is locked by the audio board fixing portion 466 of the power supply base 46 . Thereby, it is fixed to the power supply base 46 .

(4-2) Microphones The microphones 75 are provided at two locations on the power supply case 41, for example. The microphones 75 are provided at both ends of the power supply case 41 in the longitudinal direction. As a result, the user's voice can be input (collected) over a wide range. In addition, noise can be canceled by arithmetic processing such as taking the difference between the audio signals collected by the two microphones 75 .
A lead wire 753 of the microphone 75 is connected to a connector 731 of the audio board 74 . The connector 731 is provided near the end on the side opposite to the power supply board 44 . This facilitates wiring of the lead wires 753 .
As shown in FIG. 10, the microphone 75 is attached to the power supply case 41 by fitting it into the microphone housing portion 474 of the power supply cover 47 while being supported by the microphone support portion 467 of the power supply base 46 (see FIG. 9). be done.
Since the microphone 75 is arranged on the cover side plate portion 471 of the power supply cover 47 , it is separated from the power supply circuit 42 and the voice recognition circuit 72 . As a result, it is possible to prevent noise emitted from electronic components such as the transformer 432 , the capacitor 431 and the switching element 433 (see FIG. 9 ) constituting the power supply circuit 42 from being transmitted to the microphone 75 . In particular, when only one microphone 75 is provided, noise cannot be canceled as described above.
Specifically, it is preferably supported by a microphone support portion 467A shown in FIG. In FIG. 9, the reference numerals of the microphones are "467A" and "467B" so that the positions of the microphone support portions 467A can be clearly specified.
The microphone 75 is mounted with the sound collecting surface 751 facing the outside of the power supply case 41, as shown in FIG. As a result, the influence of noise from the electronic components 43 in the power supply case 41 can be reduced.
The microphone 75 is fixed to the microphone support portion 467 of the power supply cover 47 with elastic adhesive 77 . The elastic adhesive 77 is a rubber-based or polyolefin-based adhesive that is elastic even at room temperature, and is supplied (applied) by hot-melt or the like. As a result, the elastic adhesive 77 absorbs the vibration of the installation surface and the lighting device X, and the influence of the vibration of the power supply case 41 on the microphone 75 can be reduced.
When the microphone 75 is assembled in the power supply case 41, the sound collecting surface 751 of the microphone 75 is located at the same position (flat plane) as the opening edge of the outer surface of the through hole 474a of the cover side plate body portion 471a, as shown in the enlarged view of FIG. ) or inside the opening edge. In other words, on the sound collecting surface 751 , the downstream end of the sound collecting surface 751 in the gravitational direction is located on an imaginary line parallel to the gravitational direction passing through the upstream end in the gravitational direction or inside the power supply case 41 from the imaginary line. This can prevent dust from adhering to the sound collecting surface 751 of the microphone 75 .
The microphone 75 is supported by the microphone support portion 467 so that the sound collecting surface 751 thereof is vertical or faces upward. Here, the vertical direction is a direction parallel to the front/back direction, and the front direction is a direction that moves toward the inner side of the power supply case 41 toward the front side. This can prevent dust from adhering to the sound collecting surface of the microphone 75 .

4. Control Contents of Speech Recognition Section The speech recognition circuit 72 performs a step of determining whether or not the speech signal input to the microphone 75 is a wakeup word, and a step of determining whether the speech signal is a wakeup word. and determining whether the speech signal is a control word. That is, the voice recognition circuit 72 is configured to accept the control word for a predetermined time after recognizing the wakeup word. As a result, it is possible to accept a plurality of control words within a predetermined period of time without inputting another wakeup word, thereby improving convenience.
(1) Example 1
FIG. 12 is a flow chart of the speech recognition unit 721 according to this embodiment.
In example 1, the starting point of the predetermined time is the recognition (extraction) of the wakeup word.
The voice recognition unit 721 waits until a voice signal is input from the microphone 75 (N in step S101). When a voice signal is input (Y in step S101), the voice of the input voice signal is converted into text and an attempt is made to extract a wakeup word from the text of the voice (step S102). If it can be extracted (Y in step S103), the elapsed time is reset and measurement of the elapsed time is started (step S104). If the wakeup word cannot be extracted (N in step S103), it waits until the voice signal is input again.
When the voice signal is continuously input from the microphone 75 after extracting the wakeup word (Y in step S105), the voice recognition unit 721 identifies the input voice signal as a user instruction, and recognizes the voice signal. An attempt is made to extract control words from the spoken text (step S106). If it can be extracted (Y in step S107), a control signal is generated and applied to the power supply circuit 42 (step S108).
The speech recognition unit 721 performs the above-described steps S105 to S108 until the elapsed time reaches a predetermined time (for example, 5 seconds) (N in step S109).

(2) Example 2
In Example 1, the elapsed time is the time that has elapsed since the speech recognition unit 721 extracted the wakeup word. However, the time that has elapsed since the speech recognition unit 721 extracted the control word may be used as the elapsed time. In other words, in Example 2, the starting point of the predetermined time is the recognition (extraction) of the control word. As a result, the user can turn on the lighting device X without uttering the voice of the wake-up word until a predetermined time elapses (that is, until the elapsed time reaches the predetermined time) after giving an instruction to the lighting device X. Device X can be instructed.
FIG. 13 shows a flow chart of the speech recognition unit 721 at this time.
The speech recognition unit 721 performs the same processing as steps S101 to S104 described above. That is, when a voice signal is input, a wakeup word is extracted based on the voice signal, the elapsed time is reset, and measurement is started (steps S201 to S204).
The speech recognition unit 721 continues to perform the same processing as in steps S105 to S108 described above. That is, when the voice signal is input after the wakeup word is extracted, the control word is extracted based on the voice signal, and the control signal is generated and applied to the power supply circuit 42 (steps S205 to S208).
When the voice recognition unit 721 gives the control signal to the power supply circuit 42 (step S208), it resets the elapsed time and starts measuring the elapsed time (step S209). Then, until the elapsed time reaches a predetermined time (N in step S210), the above steps S205 to S209 are performed.
Note that the measurement of the elapsed time in step S209 may be performed before the control signal is given to the power supply circuit .
<Second embodiment>
In the first embodiment, the speech recognition unit 7 does not have an audio output, but it may have an audio output. A speaker, which is an example of an audio output body, can be implemented by disposing it in the power supply unit 4, for example.
1. Example 1
The speech recognition circuit may cause the speaker to output a first alert sound (eg, a "beep" sound) each time it extracts a wake-up word or control word from the spoken text. Accordingly, it is possible to notify the user that the voice recognition unit was able to extract the wake-up word or the like, that is, that the lighting device X was able to recognize the user's voice.
Specifically, for example, in FIG. 12, after extracting the wakeup word in step S203 or after extracting the control word in step S207, the speaker may output the first alert sound.

2. Example 2
In the voice recognition circuit, if the control word is not extracted before the elapsed time reaches a predetermined time, the voice recognition unit outputs a second alert sound different from the first alert sound (for example, a "beep" sound). You may output to a speaker. As a result, it is possible to notify the user that the voice recognition unit could not extract the control word, that is, that the lighting device X could not recognize the voice of the user's instruction, and instruct the lighting device X again. can be performed by the user.
FIG. 14 shows a flow chart of the speech recognition unit 721 at this time.
As in steps S101 to S104 described above, when a voice signal is input, the voice recognition unit 721 extracts a wake-up word based on the voice signal, resets the elapsed time, and starts measuring ( Steps S301-S304).
When the voice recognition unit 721 resets the elapsed time and starts measuring the elapsed time (step S304), the control word recognition flag indicating that the control word has been extracted is set to off (that is, "0"). (step S305).
Subsequently, when a voice signal is input after extracting the wakeup word, the voice recognition unit 721 extracts a control word based on the voice signal and generates a control signal, as in steps S105 to S108 described above. is given to the power supply circuit 42 (steps S306 to S309).
When the voice recognition unit 721 gives the control signal to the power supply circuit 42 (step S309), it sets the control word recognition flag to ON (that is, "1") (step S310). If it cannot be extracted (N in step S308), the control word recognition flag remains off.
The speech recognition unit 721 performs the processes of steps S306 to S310 described above until the elapsed time reaches a predetermined time (N in step S311). When the elapsed time reaches the predetermined time (Y in step S311) and the control word recognition flag is off (Y in step S312), the second alert sound is output from the speaker (step S313).

3. Example 3
If the user's instruction is an instruction that the lighting device X cannot perform, the voice recognition circuit generates a third alert sound (e.g., a "beep-beep" sound that is different from the first and second alert sounds). ) may be output to the speaker.
For example, when an instruction to turn on an already lit lighting device X is given, or when the upper limit (or lower limit) for adjusting the light amount or color temperature is reached, they are further increased (or decreased). By outputting a third alert sound from the speaker when an instruction to You can keep it from happening again and again.

FIG. 15 shows a flow chart of the speech recognition unit 721 at this time.
Here, the lighting control unit 425 (see FIG. 11), if the lighting power generation unit 423 could not perform dimming lighting or toning lighting based on the output duty ratio, A failure signal indicating that dimming lighting could not be performed) is given to the speech recognition circuit 72 (speech recognition section 721).
The speech recognition unit 721 performs the same processing as in steps S101 to S108 described above (steps S401 to S408).
After giving the control signal to the power supply circuit 42 (step S408), if the voice recognition unit 721 receives a failure signal from the power supply circuit 42 (lighting control unit 425) (Y in step S409), it emits a third alert sound. is output to the speaker (step S410). Then, until the elapsed time reaches a predetermined time (N in step S411), the above steps S405 to S410 are performed.

Here, the lighting control unit 425 outputs a failure signal to the speech recognition circuit 72 when the lighting power generation unit 423 cannot perform dimming lighting or toning lighting based on the output duty ratio. (speech recognition unit 721), but if dimming lighting or toning lighting cannot be performed, the third alert sound is output to the speaker by itself without giving a failure signal to the speech recognition circuit 72. good too.

Another mounting member includes a hanging member, etc. In this case, the lighting device is a so-called hanging type lighting device that is attached to the mounting surface via the hanging member.
Although the lighting device X uses the hooking blade 49 as the mounting member, a tap screw or the like may be used as the mounting member.
The lighting device X includes the power supply unit 4, but may not include the power supply unit. As such a lighting device, for example, there is a device in which a light source unit receives power from a power supply unit separate from the lighting device through a mounting member. In this case, the voice recognition unit may be housed in a voice recognition case and attached to a base resin material or the like, or may be attached to a power supply unit separate from the lighting device.
The lighting device X is provided with a protective cover 5 for safety when the device is installed on the mounting surface, but the protective cover may not be provided depending on the structure. As such a lighting device, there is, for example, a device in which a translucent cover is fixed so as not to come off from the device main body during normal operation by the user.
Although the illumination device is configured to be remote controllable, it may be configured so that it cannot be controlled by the remote controller 78 .

2. Translucent Cover The shape of the translucent cover is circular when viewed from the front side, but may be square, rectangular or other shapes.
The translucent cover 8 is made up of two members, the back cover 81 and the front cover 83, but may be made up of one member, or may be made up of three or more members, for example.
The translucent cover 8 is detachably mounted on the protective cover 5, but may be detachably mounted on the base resin material, may be fixed on the base resin material, or may be mounted on a separate cover other than the protective cover. It may be detachably attached to the base resin material via a member, or may be fixed to the base resin material via another member other than the protective cover.

3. Apparatus body (1) Base resin material The base resin material 2 is an integrally molded product made of a resin material, but the covered cylindrical part and flat part may be separately formed and then assembled. The structure may be such that the base member is attached to an adapter provided with a hooking blade.
(1-1) Light source holding portion The flat portion 23, which is an example of the light source holding portion, has recessed portions 231, 232, and 233, but other structures may be used as long as the flat portions can be reinforced. However, it may have other shapes and may not have a recessed portion if it does not need to be reinforced.
The flat portion 23, which is an example of the light source holding portion, has a portion parallel to the horizontal direction, but may have a portion inclined with respect to the horizontal direction. You may have both the part which inclines with respect to a direction.

(1-2) Mounting Member Holding Portion The lidded tubular portion 21, which is an example of the mounting member holding portion, had the hooking blade 49 attached to the recessed region 213a, but the recessed region is not provided and the hooking portion is hooked to another portion. A blade 49 may be attached.
The mounting member holding portion is configured by the lidded tubular portion 21 as an example. 21 as a structure included in the flat portion (23) which is an example of the light source holding portion (including the deformation described in the above "(1-1) Light Source Holding Part"). good too.

(1-3) Covered Cylindrical Portion The covered cylindrical portion 21 has the locking mechanism 27 in the recessed area 213a. Mechanism need not be provided.
(1-4) Flat portion The flat portion 23 has a circular shape when viewed from the front side, but may have other shapes such as a square and a rectangle.
A part of the back surface of the flat portion 23 serves as a power holding portion for holding the power supply unit 4, but a part of the surface of the flat portion may serve as a power holding portion for holding the power supply unit.
If the lighting device does not include a power supply unit (such as a separate power supply unit structure), the inner recessed portion 231 and the outer recessed portion 232 of the flat portion 23 may be annular as a whole.
(1-5) Grooves The base resin material 2 has grooves 25, but may not have grooves. In this case, it can be implemented by engaging the protective cover side mounting portion 54 and the translucent cover side mounting portion 813 on the front side of the flat portion 23 .

(2) Light source unit The shape of the light source unit 3 is circular when viewed from the front side, but it may be square, rectangular, or other shape in accordance with the shape of the lighting device. The light source unit 3 includes three light source modules 31A, 31B, and 31C, but may be configured with one, two, or four or more light source modules.
The light source module 31 includes a wiring body 35 corresponding to a substrate made up of a plurality of spaced-apart conductive pieces 37, but instead of the wiring body, a substrate made of an insulating material and having a wiring pattern may be provided.
The light source unit 3 includes the LED element 33, but may include other light emitting elements.

(3) Power supply unit In the power supply unit 4, the power supply board 44 on which a plurality of electronic components (43) constituting the power supply circuit 42 are mounted is housed in the power supply case 41. The power supply board may be covered with a power supply cover. In this case, the voice input device may be provided on the power supply cover, may be provided on another unit such as the light source unit, or may be provided in a dedicated case for the voice recognition unit provided independently from the power supply case. may be provided.
The power substrate 44 may be one or more. For example, a board on which the light control circuit is mounted and a board on which the color control circuit is mounted may be provided separately from the power supply board. Electrical connection between the power supply unit 4 and the light source unit 3 is achieved by bringing the conductive pin 443 inserted from the power supply board 44 through the through hole 234a (see FIG. 6) of the base resin material 2 into contact with the wiring body (or substrate) of the light source unit 3. However, for example, the connectors provided on the power supply board and the wiring body (or board) may be connected with a cable.

(4) Speech Recognition Unit (4-1) The speech recognition unit 7 has two speech input bodies 75, but may have one or three or more.
(4-2) Although the voice recognition unit 7 has the voice board 74 separately from the power board 44 of the power supply circuit 42, for example, electronic components for the voice recognition unit may be mounted on the power board. Conversely, part of the power supply circuit, for example, the lighting control section may be mounted on the audio board.
(4-3) The voice input member 75 of the voice recognition unit 7 is provided on the power supply case 41, but may be provided on other members such as a base resin material and a light source unit.
(4-4) The speech recognition unit 721 compared the wakeup word and the control word with the text of the recognized speech from the viewpoint of whether or not they are the same in appearance.
However, collation may be performed from the viewpoint of whether or not the text of the recognized voice and the wake-up word are partially in common, or the concept of the text of the recognized voice and the concept of the wake-up word are common. You may collate from the viewpoint of whether or not.
(4-5) The control word may include, in addition to the words described in this embodiment, words indicating how much the amount of light and color temperature change. The speech recognition unit 721 may then generate a control signal using the control word.
For example, if the voice recognition unit 721 can extract the control words “90%” and “bright” from the voice text, it may give the lighting control unit 425 a control signal to set the light amount to 90% of the maximum.

(4-6) After extracting the wake-up word, when the voice signal is input (Y in step S105 in FIG. 12), the voice recognition unit 721 attempts to extract the control word from the voice signal. However, an attempt may be made to extract not only the control word but also the wakeup word.
At this time, if the wakeup word can be extracted instead of the control word, the elapsed time may be reset and measurement of the elapsed time may be started (returning to step S104 to continue the processing), and the control word is extracted. The same processing as in the case where extraction is not possible (N in step S107) may be performed, or a predetermined alert sound or the like may be output from the speaker to prompt the user to give another instruction.

(4-7) The speech recognition unit 721 converts the speech signal into text when recognizing the speech, but for example, discrimination of the tone of the speech may be added to the input speech signal. In this case, when the determined tone of the voice matches the tone of the voice of the user registered in the lighting device X (hereinafter referred to as "registered user"), the voice (that is, the tone is determined) It is also possible to match the text of the (spoken voice) with a wake-up word or the like.
For example, the voice recognition unit 721 uses a known frequency analysis method such as Fourier transform to determine the voice tone of the input voice signal, and recognizes the determined voice tone and the voice tone stored in the storage unit 434 in advance. This can be done by comparing the tone of voice of the registered user and, when both match, matching the text of the voice with the wake-up word or the like.

(4-8) In example 1 of the second embodiment, the speech recognition unit 721 causes the speaker to output the first alert sound each time a wakeup word or the like is extracted. However, instead of the first alert sound, the voice of the extracted text such as the wakeup word may be output to the speaker. That is, the user's voice may be parroted back.
For example, every time the speech recognition unit 721 extracts a wake-up word or the like from the speech text of the input speech signal, the speech text is converted into speech using a known technique (for example, waveform concatenation synthesis). It can be implemented by outputting to the speaker by
Alternatively, the extracted wakeup word or the like may be converted (stored) into voice in advance and output.

(4-9) In example 3 of the second embodiment, the voice recognition unit 721 outputs the third alert sound when an instruction that cannot be performed by the lighting device X is given. Instead of the alert sound, the instruction voice may be output from the speaker, or the instruction voice may be added with a negative voice such as "I can't do it" and output from the speaker.

(5) Protective Cover The protective cover 5 has an inner tubular portion 52 and an outer tubular portion 53 extending in the direction of the central axis. 53 are fixed to the base resin material 2 in such a state that they are fitted into the groove-shaped portions 25 of the base resin material 2 respectively.
However, for example, the protective cover includes an inner flange that protrudes radially inward from the inner peripheral edge of the annular bulging portion 51, and a protective cover that extends radially outward from the outer peripheral edge of the annular bulging portion 51. It may be fixed to the base resin material in such a manner that the inner flange abuts against the inner circumference of the flat portion and the outer flange abuts against the outer circumference of the flat portion. Further, the protection cover may have a structure that does not have the inner tubular portion 52 and/or the outer tubular portion 53 as long as the annular bulging portion 51 can be directly fixed to the base resin material 2 .
The annular bulging portion 51 has a recessed portion 511 that supports the circumferentially adjacent (facing) portions of the three light source modules 31A, 31B, and 31C from the front side. As long as it can be pressed against the flat portion, it does not have to have a recessed portion.
A fixing portion 56 of the protective cover 5 for fixing the protective cover 5 to the base resin material 2 with a screw is provided adjacent to (connected to) the protective cover side mounting portion 54 in the circumferential direction. It may be provided so as to be spaced apart from the mounting portion 54 in the circumferential direction. In this case, the screw hole portion 255 of the base resin material 2 also needs to be provided at a portion corresponding to the fixing portion 56 .
