(embodiment mode)
The illumination device 1 according to the embodiment will be described with reference to fig. 1 and 2. Fig. 1 is a perspective view showing a state in which the lighting device 1 according to the embodiment is installed on a ceiling. Fig. 2 is a block diagram showing the configuration of the illumination device 1 according to the embodiment.
The lighting device 1 is a lighting fixture disposed on a building material such as a ceiling or a wall of a building such as a house or a store, for example, and irradiates illumination light to brighten a spatial region such as a room. As shown in fig. 1, the lighting device 1 of the present embodiment is installed on a ceiling. In this case, the lighting device 1 may be connected to and fixed to a ceiling provided on a ceiling, may be directly attached to and fixed to a ceiling surface, or may be embedded in a through hole formed in the ceiling.
The lighting device 1 is installed on a ceiling or a wall surface of, for example, an entrance, a shoe cabinet, a walk-in locker room, a platform of a toilet or a staircase, but is not limited thereto. As described later, the lighting device 1 has functions of deodorizing, and sterilizing, and therefore can be installed in a place where there is a concern about odor, such as a toilet.
As shown in fig. 1, the lighting device 1 includes a housing 10 and a translucent cover 20 provided in front of the housing 10. The housing 10 is, for example, a flat cylindrical shape. An illumination light source 120 is disposed inside the housing 10, and light emitted from the illumination light source 120 is transmitted through the translucent cover 20 and emitted as illumination light. The light-transmitting cover 20 is, for example, a diffusion cover that diffuses light. In this case, the illumination light emitted from the light-transmissive cover 20 is diffused light.
The lighting device 1 of the present embodiment is a lighting fixture having an ion generating function, and emits ions. A plurality of slits 11 extending in the circumferential direction are formed in the side circumferential surface of the housing 10, and generated ions are emitted from the slits 11 to the outside of the illumination device 1.
The ions released from the lighting device 1 are, for example, negative ions called nano water ions (nanoe, ナノイー, registered trademark). The nano-sized water ions are nano-sized (e.g., about 5 a diameter)
Figure BDA0001398865140000031
20nm) of negative ions encapsulated by corpuscle water, and is rich in hydroxyl free radicals. The nano water ions have an action of inhibiting the activity of allergens (allergic substances) entering the air or deep in the fibers, and have an action of deodorizing/deodorizing, a bactericidal action and an antiviral action. Therefore, the nano water ions diffuse into the room, and for example, the room area or the curtain can be deodorized or deodorized, the allergen or virus suspended or attached to the room can be inactivated, or the mold or bacteria suspended or attached to the room can be sterilized. In particular, the nano water ions have high reactivity and have the ability to act on odorous components to decompose into odorless components. Furthermore, the nano water ions are excellent in weak acidity for hair and skin, and are useful for human.
In addition, the nano water ions can exist in the air for a longer time (about 6 times the life of the negative ions) than the case of existing as the negative ions alone, and can be generally diffused and suspended for a long time in the entire space area where the lighting device 1 is provided due to being very small to the nano size.
In this way, the illumination device 1 not only irradiates illumination light to illuminate a spatial region, but also emits ions to the spatial region. In the illumination device 1, the power required to emit light from the illumination light source 120 is larger than the power required to generate ions. That is, in the present embodiment, the main function of the illumination device 1 is to irradiate illumination light, and the release of ions is an auxiliary function. For example, the power required to emit light from the illumination light source 120 is 10W, and the power required to generate ions is 5W. Alternatively, the main function and the auxiliary function may be replaced with each other, and the main function of the illumination device 1 may be configured to emit ions and the auxiliary function may be configured to irradiate illumination light.
As shown in fig. 2, the illumination device 1 includes an illumination unit 100 that irradiates illumination light, an ion emitting unit 200 that emits ions, and a terminal block 300. The illumination unit 100, the ion discharging unit 200, and the terminal block 300 are accommodated in the housing 10 shown in fig. 1.
The illumination unit 100 is a device that irradiates illumination light to a space region where the illumination device 1 is installed, and includes a 1 st power supply/control section 110, an illumination light source 120, and an illumination sensor section 130.
The 1 st power supply/control unit 110 is a power supply/control unit for illumination, and has a power supply function of generating power for causing the illumination light sources 120 to emit light, and a control function of controlling the illumination mode (light emission state) of the illumination light sources 120.
The 1 st power supply/control unit 110 converts ac power supplied from the terminal block 300 into dc power, for example, and supplies the dc power to the illumination light source 120 to cause the illumination light source 120 to emit light. The 1 st power supply/control unit 110 has an H terminal (1 st terminal), an N terminal (2 nd terminal), and an LOD terminal (3 rd terminal). The H terminal and the N terminal are connected to the terminal block 300, and ac power supplied from the terminal block 300 to the 1 st power supply/control unit 110 is input to the H terminal and the N terminal. The LOD terminal is connected to the 2 nd power supply/control section 210.
The 1 st power supply/control unit 110 changes the illumination mode of the illumination light source 120 by performing dimming control or color control of the illumination light source 120, or by performing blinking/flash lighting control of the illumination light source 120.
The plurality of circuit elements include a power supply circuit element constituting a power supply circuit for generating power for causing the illumination light source 120 to emit light, and a control circuit element constituting a control circuit for controlling the illumination mode of the illumination light source 120.
The illumination light source 120 is fixed at a predetermined position in the housing 10 by a fixing member such as a screw or an adhesive. The illumination light source 120 is a light source module as a light source unit of the illumination device 1, and the illumination device 1 emits, for example, white light as illumination light for illuminating a spatial region. In the present embodiment, the illumination Light source 120 is an LED module using an LED (Light Emitting Diode) as a Light source. For example, the light source 120 for illumination is of a COB (Chip On Board) type, and includes a substrate, a plurality of LED chips mounted On the substrate, and a sealing member for sealing the LED chips.
As the substrate, a ceramic substrate, a resin substrate, a metal base substrate, or the like is used. The LED chip is, for example, a bare chip that emits monochromatic visible light. The LED chip is a blue LED chip that emits blue light when energized. The sealing member is, for example, a translucent resin. The sealing member of the present embodiment contains a fluorescent material as a wavelength conversion material for converting the wavelength of light from the LED chip. The sealing member is, for example, a phosphor-containing resin in which a phosphor is dispersed in a silicone resin. When the LED chip is a blue LED chip, a yellow phosphor such as YAG can be used as the phosphor particles to obtain white light. In the present embodiment, the sealing member is formed in a circular shape to seal all the LED chips together, but a plurality of LED chips may be sealed in a linear shape for each row, or each LED chip may be sealed independently.
In this case, the illumination light source 120 emits light from the blue LED chip by the dc power supplied from the 1 st power supply/control unit 110. Thereby, the yellow phosphor absorbs a part of the blue light of the blue LED chip and is excited, and the yellow light is emitted from the yellow phosphor. The yellow light is mixed with the blue light that is not absorbed by the yellow fluorescent material to become white light, and the white light is emitted from the illumination light source 120.
The illumination light source 120 may have a structure capable of adjusting light and a structure capable of adjusting color. Further, the 1 st power supply/control part 110 is constituted by a mounting substrate and a plurality of circuit elements mounted on the mounting substrate.
The illumination sensor unit 130 is a sensor unit having a human detection sensor and an illuminance sensor, for example. The human body sensor is a sensor for detecting the presence or absence of a human body around the lighting device 1. For example, if a detection signal (human detection signal) indicating the presence of a human is detected by the human detection sensor, the illumination light source 120 emits light. The illuminance sensor is a sensor for detecting the illuminance around the lighting device 1. For example, a detection signal (illuminance signal) indicating illuminance is detected by an illuminance sensor, and when an illuminance value obtained from the detection signal is lower than a predetermined illuminance value, the illumination light source 120 emits light.
The ion emitting unit 200 is a device having a function of emitting ions to a space region where the lighting device 1 is provided. By releasing ions from the ion releasing unit 200 for a certain period of time, it is possible to deodorize/deodorize a spatial area, to inactivate allergens, viruses, or the like, or to sterilize molds, bacteria, or the like in the spatial area. In addition, in order to obtain 90% of deodorizing effect in the space region around two tatami of the house, the nano water ions can be released for about 8 hours.
The ion discharge unit 200 includes a 2 nd power supply/control unit 210, an ion generation unit 220, a display light source 230, and a blower 240.
The 2 nd power supply/control unit 210 has a power supply function of generating electric power for operating the ion generating unit 220 and the blower 240 and generating electric power for emitting light from the display light source 230, and has a control function of controlling an operation display mode (light emission state) of the display light source 230.
The power supply source of the 2 nd power supply/control section 210 is the 1 st power supply/control section 110. That is, the 2 nd power supply/control unit 210 is supplied with ac power from the 1 st power supply/control unit 110. Specifically, the ac power supplied to the 2 nd power supply/control unit 210 is supplied from the LOD terminal of the 1 st power supply/control unit 110 and one terminal of the terminal block 300. In the present embodiment, when power is supplied from the 2 nd power supply/control unit 210 to the 1 st power supply/control unit 110, a delay time is set.
Further, the power supply from the 1 st power supply/control section 110 to the 2 nd power supply/control section 210 is performed via a triac. That is, a triac is connected to a power supply path from the 1 st power supply/control unit 110 to the 2 nd power supply/control unit 210. The triac is incorporated in, for example, the 1 st power supply/control unit 110 or the 2 nd power supply/control unit 210, and can be turned on or off by a 1-2 switching operation performed by the wall switch 2.
Here, the 1-2 switch operation (one-two switch function) is an operation of continuously pressing the wall switch 2 twice in a short time. For example, when the wall switch 2 is pressed 2 nd time within a predetermined time (for example, 2 seconds) after 1 st pressing of the wall switch 2, it is regarded that the 1-2 switch operation is performed.
The 2 nd power supply/control unit 210 supplies predetermined electric power to the ion generating unit 220 and the blower 240, respectively, in order to operate the ion generating unit 220 and the blower 240. The 2 nd power supply/control unit 210 supplies predetermined power to the display light source 230 to cause the display light source 230 to emit light. Specifically, the 2 nd power supply/control unit 210 converts ac power supplied from one terminal of the terminal block 300 and the LOD terminal of the 1 st power supply/control unit 110 into dc power, and the display light source 230 emits light when the dc power is supplied to the display light source 230.
Further, the 2 nd power supply/control unit 210 controls the ion generating unit 220 and the blower 240. For example, the 2 nd power supply/control unit 210 controls the start and stop of the operation of the ion generating unit 220 and the blower 240 (i.e., the ion release time), and controls the amount of ions released from the ion release unit 200.
The 2 nd power supply/control part 210 is constituted by a mounting substrate and a plurality of circuit elements mounted on the mounting substrate.
Specifically, the 2 nd power supply/control unit 210 includes a plurality of circuit elements including a driving circuit element constituting a driving circuit for driving the ion generating unit 220 and the blower 240. The drive circuit elements include a power supply circuit element constituting a power supply circuit that generates electric power for operating the ion generating unit 220 and the blower 240, and a control circuit element constituting a control circuit for controlling the ion generating unit 220 and the blower 240. The drive circuit element for the ion generating means and the drive circuit element for the blower may be mounted on the same mounting board or may be mounted on different mounting boards.
The plurality of circuit elements constituting the 2 nd power supply/control unit 210 include a power supply circuit element constituting a power supply circuit for generating power for causing the display light source 230 to emit light, and a control circuit element constituting a control circuit for controlling the illumination mode of the display light source 230.
The ion generating part 220 is an ion generator for generating ions. In the present embodiment, the ion generating means 220 generates nano water ions. Specifically, the ion generating unit 220 generates nano-sized water ions without water supply. In this case, the ion generating member 220 includes, for example, an ion generating portion having a needle-shaped discharge electrode, a high voltage generating circuit for applying a high voltage (for example, about 6000V) to the needle-shaped discharge electrode, and a peltier element for cooling the needle-shaped discharge electrode. The needle-like discharge electrodes are cooled by the peltier effect of the peltier elements, and dew is condensed. The high voltage generation circuit can generate atomized nano water ions by applying a high voltage to moisture in the air condensed on the needle-like discharge electrode. Ions (nano water ions, nanoe) generated by the ion generating means are released from a slit 11 provided in the housing 10 to the outside of the housing 10. In the present embodiment, since the blower 240 is disposed in the front stage of the ion generating member 220, the outside air taken in by the blower 240 is blown out to the outside of the casing 10 together.
The ion generating unit 220 configured as described above operates by the power supplied from the 2 nd power supply/control unit 210. That is, ions are generated by supplying power from the 2 nd power supply/control unit 210 to the ion generating unit 220.
Further, the ion generating section 220 can control the driving state by performing 1-2 switching operation of the wall switch 2. In the present embodiment, the opening/closing of the ion generating unit 220 is controlled by the user performing 1-2 switching operation of the wall switch 2. For example, if the user performs a 1-2 switching operation on the wall switch 2, the on/off of the triac provided in the power supply path between the 1 st power supply/control part 110 and the 2 nd power supply/control part 210 is controlled, and the power supply from the 1 st power supply/control part 110 to the 2 nd power supply/control part 210 can be stopped or restarted. This can stop or restart the operation of the ion generating means 220.
The display light source 230 emits light in an operation display mode indicating an operation state of the ion generating unit 220. That is, the display light source 230 is an indicator showing the operation state of the ion generating means 220.
As the display light source 230, for example, a bullet type LED element may be used, but the present invention is not limited thereto, and an SMD (Surface Mount Device) type package type LED element may be used, or a small COB type LED module may be used. The display light source 230 emits, for example, blue or green colored light, but is not limited thereto. The illumination light source 120 emits monochromatic light with a constant light output, but may be configured to be capable of controlling light adjustment and color adjustment. The display light source 230 is fixed at a predetermined position in the housing 10.
The display light source 230 emits light by the power supplied from the 2 nd power supply/control unit 210 so as to know whether or not the ions are emitted from the illumination device 1. For example, when the ion emitting unit 200 operates normally, the display light source 230 emits light by the power supplied from the 2 nd power supply/control unit 210. For example, when the display light source 230 is a bullet-type blue LED element, the display light source 230 emits blue light having a constant light output. By emitting light from the display light source 230 in this manner, the user knows that ions are being released from the ion releasing unit 200.
The blower 240 is a blower fan that blows the ions generated by the ion generating unit 220. Specifically, the blower 240 generates an air flow for diffusing the ions generated by the ion generating member 220 to the outside of the illumination device 1. That is, the blower 240 assists the diffusion of the ions generated by the ion generating member 220 by blowing. The blower 240 includes, for example, a casing, an impeller disposed in the casing, and a motor for rotating the impeller, and sucks and discharges air (outside air) outside the lighting device 1. When the blower 240 is operated, the outside air is sucked into the casing 10 through the suction port provided in the casing 10, and the sucked outside air is discharged to the outside of the casing 10 through the slit 11 of the casing 10 together with the ions generated by the ion generating member 220.
Further, the blower 240 can control the driving state by performing 1-2 switching operation of the wall switch 2. In the present embodiment, if the user performs the 1-2 switching operation on the wall switch 2, the power supply from the 1 st power supply/control unit 110 to the 2 nd power supply/control unit 210 can be stopped or restarted by controlling the on/off of the triac provided in the power supply path between the 1 st power supply/control unit 110 and the 2 nd power supply/control unit 210 as described above. This can stop or restart the operation of the blower 240.
Further, a filter 400 through which the outside air sucked by the blower 240 passes is provided in the casing 10. The filter 400 is disposed between the suction port of the casing 10 and the blower 240, for example. By passing the outside air through the filter 400, the filter 400 can suck and remove dust, dirt, or the like contained in the outside air.
The terminal block 300 is connected to a commercial power supply via a wire or the like. The terminal block 300 and the commercial power supply are electrically connected via the wall switch 2. That is, the lighting device 1 and the commercial power supply are electrically connected via the wall switch 2.
Here, the operation of the illumination device 1 of the present embodiment will be described together with the operation of the illumination device of the comparative example with reference to fig. 3 and 4. Fig. 3 is a timing chart for explaining an example of the operation of the illumination device of the comparative example. Fig. 4 is a timing chart for explaining an example of the operation of the illumination device 1 according to the embodiment. The lighting device of the comparative example is different from the lighting device 1 of the present embodiment in control and operation, and the configuration of the lighting device of the comparative example is the same as the configuration of the lighting device 1 of the present embodiment shown in fig. 2. Therefore, the operation of the lighting device of the comparative example will be described with reference to fig. 2.
The lighting device of the comparative example and the lighting device according to the present embodiment are both operated by the wall switch 2.
In the illumination device of the comparative example, for example, as shown in fig. 3, when the wall switch 2 shown in fig. 2 is pressed at time T1, the wall switch 2 is turned ON (ON), the illumination light source 120 emits light, illumination light is emitted from the illumination device 1, ions are generated by the ion generating means 220, and ions are released from the illumination device 1.
Specifically, as shown in fig. 2, if the user presses the wall switch 2, ac power is supplied from the commercial power supply to the terminal block 300 of the lighting device 1. The ac power supplied to the terminal block 300 is input to the H terminal and the N terminal of the 1 st power supply/control unit 110. The 1 st power supply/control unit 110 converts ac power from the terminal block 300 into dc power and outputs the dc power to the illumination light source 120. Thereby, the illumination light source 120 emits light.
As shown in fig. 3, when a certain time (for example, 10 minutes) has elapsed since the start of the power supply to the illumination light source 120, the 1 st power supply/control unit 110 stops the power supply to the illumination light source 120. That is, when the light emission of the illumination light source 120 has elapsed for a certain period of time, the illumination light source 120 is automatically turned off.
In addition, even if the user does not press the wall switch 2, the illumination device 1 irradiates illumination light by detecting a predetermined detection signal by the illumination sensor unit 130. For example, in a state where the illuminance sensor of the illumination sensor unit 130 detects a signal having a value lower than a predetermined threshold value of the illuminance around the illumination device 1 as the detection signal, and further in a case where the human detection sensor of the illumination sensor unit 130 detects the presence of a human around the illumination device 1 as the detection signal, the 1 st power supply/control unit 110 automatically emits light from the illumination light source 120. That is, as shown in fig. 3, the user does not press the wall switch 2, but the human detection sensor automatically controls the lighting light source 120 to be turned on and off.
On the other hand, if the user presses the wall switch 2 at time T1, ac power is also supplied to the 2 nd power supply/control unit 210 via the terminal block 300 and the LOD terminal of the 1 st power supply/control unit 110. The 2 nd power supply/control unit 210 supplies electric power to the ion generating unit 220, the blower 240, and the display light source 230. Accordingly, at time T1, the ion generating unit 220 and the blower 240 are driven, and the display light source 230 emits light while emitting ions from the ion emitting unit 200. By emitting light from the display light source 230, the user knows that ions are being released from the ion releasing unit 200.
As shown in fig. 3, the ion emitting unit 200 is turned on to continuously emit ions for a certain time (for example, 10 hours) from the start of the supply of electric power to the ion generating means 220, the blower 240, and the display light source 230, but after the lapse of the certain time (when the time T2 is reached from the time T1), the 2 nd power supply/control means 210 stops the supply of electric power to the ion generating means 220, the blower 240, and the display light source 230. Thereby, at time T2, the ion emission from the ion emitting unit 200 is automatically stopped, and the display light source 230 is automatically turned off.
Then, as shown in fig. 3, after a certain time (for example, 14 hours) has elapsed since the stop of the supply of electric power to the ion generating means 220 and the blower 240, the effects of deodorization, sterilization, and the like by the ions are lost. Therefore, in order to obtain a desired effect by the ions, for example, the supply of electric power to the ion generating unit 220 and the blower 240 is restarted at time T1, and the ions are released again. The restart of the power supply is automatically performed regardless of the wall switch 2 (i.e., regardless of the user's intention).
Since a certain time is required to obtain a desired effect by the ions, the illumination device of the comparative example repeats the release of the ions by the ion releasing means 200 for each certain time period as shown in fig. 3.
However, in the operation of the lighting device of the comparative example, the blower 240 is driven for a long time by the operation of the ion emitting unit 200. Therefore, the operating sound of the blower 240 may be generated for a long time, and the noise may be perceived as harsh noise. For example, operating sound such as motor sound of the blower 240 and rotational sound of the impeller may be perceived as noise.
Therefore, in the lighting device 1 of the present embodiment, the wall switch 2 is switched 1-2 to stop the driving of the blower 240. For example, as shown in fig. 4, if the user performs a 1-2 switching operation on the wall switch 2 at time T3, the power supply from the 2 nd power supply/control unit to the ion generating unit 220 and the blower 240 is stopped, and the driving of the ion generating unit 220 and the blower 240 is stopped. This can stop the generation of the operating sound of the blower 240, and thus can eliminate the harsh noise caused by the blower 240. In the present embodiment, since the driving of the ion generating means 220 is also stopped, even when a harsh noise is generated by the ion generating means 220, the noise can be eliminated.
In addition, as shown in fig. 4, in order to restart the release of ions, it is sufficient to perform the 1-2 switching operation of the wall switch 2 again (time T1'). Accordingly, the supply of electric power from the 2 nd power supply/control unit to the ion generating unit 220 and the blower 240 is restarted, and the ion generating unit 220 and the blower 240 can be driven. Thereby, ions are released from the ion releasing unit 200.
As shown in fig. 4, the release of ions may be automatically stopped by stopping the supply of electric power from the 2 nd power supply/control unit 210 to the ion generating unit 220 and the blower 240 after a certain time has elapsed (when the time T2 'comes from the time T1'), or may be stopped by forcibly stopping the driving of the ion emitting unit 200 by performing 1-2 switching operation on the wall switch 2.
As described above, the illumination device 1 according to the present embodiment is an illumination device that operates by the wall switch 2, and includes the 1 st power supply/control unit 110, the illumination light source 120 that emits light by the power supplied from the 1 st power supply/control unit 110, the 2 nd power supply/control unit 210, the ion generating unit 220 that operates by the power supplied from the 2 nd power supply/control unit 200, and the blower 240 that blows air to the ions generated by the ion generating unit 220. The blower 240 controls the driving state by performing 1-2 switching operation of the wall switch 2.
As described above, in the lighting apparatus 1 of the present embodiment, since the driving state of the fan 240 can be controlled by performing the 1-2 switching operation on the wall switch 2, the user can easily perform the driving control of the fan 240 in the lighting apparatus 1. That is, the drive control of the blower 240 can be performed without using a special external switch, a remote controller, or the like.
Further, by controlling the driving state of the air blower 240 by performing the 1-2 switching operation on the wall switch 2, when the user feels the operating sound of the air blower 240 as a harsh noise, it is sufficient to perform the 1-2 switching operation on the wall switch 2 to appropriately drive and control the air blower 240 so that the operating sound of the air blower 240 becomes small.
In the lighting device 1 of the present embodiment, the wall switch 2 is switched 1-2 to control the on/off of the blower 240.
Thus, when the user feels the operating sound of the blower 240 as a harsh noise, the wall switch 2 may be switched 1-2 to forcibly turn off (stop) the blower 240. This makes it possible to eliminate harsh noise caused by the operating sound of blower 240 at the will of the user.
In the lighting device 1 of the present embodiment, the power supply source of the 2 nd power supply/control unit 210 is the 1 st power supply/control unit 110.
With this configuration, the structure for supplying power to the ion emitting unit 200 can be simplified. Further, with this configuration, since the power supply can be shared by the 2 nd power supply/control unit 210 for ion generation and the 1 st power supply/control unit 110 for illumination, by installing a countermeasure circuit for noise, surge, inrush current, or the like in the 1 st power supply/control unit 110, the countermeasure circuit in the 2 nd power supply/control unit 210 on the subsequent stage side can be simplified. That is, the countermeasure circuit can be shared between the 1 st power supply/control unit 110 and the 2 nd power supply/control unit 210.
In the lighting device 1 of the present embodiment, a delay time is set when power is supplied from the 2 nd power supply/control unit 210 to the 1 st power supply/control unit 110.
With this configuration, since the reset of the ion emitting unit 200 side can be performed, malfunction can be prevented.
In the lighting device 1 of the present embodiment, the ion generating means 220 or the blower 240 may be controlled in accordance with the timing of pressing the wall switch 2 or the number of times the wall switch 2 is pressed in the 1-2 switching operation.
Thus, the user can adjust the amount of ions released from the ion releasing unit 200 and the diffusion region of the ions by adjusting the amount of ions generated by the ion generating means 220 or controlling the rotation speed of the blower 240, for example, by performing only 1-2 switching operations.
