The ion generation unit 100 used for the illumination device 200 will be described with reference to FIGS.
The ion generation unit 100 includes a main body base 30 including a substantially rectangular parallelepiped case 40, an ion generation element A31, an ion generation element B32, an axial flow fan 33 (hereinafter referred to as a fan 33), and the like attached to the inside of the case 40. A suction grill 20 that is attached to the main body base 30 and forms a ventilation path of air sucked from the outside together with the main body base 30, and a front cover 10 (hereinafter referred to as the cover 10) that is provided on the front surface of the case 40 and covers the main body base 30 and the suction grill 20. Is written).
The case 40 is a substantially rectangular parallelepiped case formed of a synthetic resin such as plastic, and mounting protrusions 42 provided on the back surface of the main body base 30 are provided in a plurality of mounting holes 41 provided on the bottom surface of the case 40. By fitting, the main body base 30 can be mounted and accommodated inside the case 40. Further, the squares of the case 40 have screw holes 43 for screwing to the bottom surface of the housing 202 of the lighting device 200, respectively.

  The main body base 30 is formed of a synthetic resin such as plastic and is a substantially rectangular parallelepiped case that is slightly smaller than the case 40, and a pair of opposing side surfaces 45 are inclined by approximately 45 ° with respect to the bottom surface. In addition, an ion light emitting element A31 and an ion generating element B32 are attached in the vicinity of the front end portions of the pair of side surfaces 45, respectively. Specifically, the ion generating element A31 and the ion generating element B32 are pressed and fixed to the inclined surface which is the side surface 45 by a fixing plate 34 having a locking portion formed at the tip. Moreover, since the ion light emitting element A31 and the ion generating element B32 can be removed by releasing the fixed plate 34, the structure is detachable.

As shown in FIG. 4, a hemispherical throttle portion 37 protruding in the front direction is formed at the center of the bottom surface of the main body base 30, and a fan 33 having a plurality of blades is attached to the throttle portion 37. It has been.
By driving the fan 33, the air sucked into the main body base 30 through the air suction port 15 of the cover 10 and the suction hole 25 of the suction grill 20 is blown to the throttle unit 37. The blown air can smoothly flow from the bottom surface of the main body base 30 in the side surface direction due to the protruding shape of the throttle portion 37. Furthermore, since the side surface 45 is inclined, the air that has reached the side surface 45 can flow smoothly toward the front surface of the main body base 30 along the inclination. That is, the protruding shape of the throttle portion 37 and the inclined shape of the side surface 45 of the main body base 30 have an effect of smoothly flowing air, and the throttle portion 37 and the side surface 45 function as a rectifying portion.

The main body base 30 has a drive control unit 35 for controlling the driving of the ion generation unit 100 on the outer surface, a display unit 36 having a plurality of display LEDs 437 for displaying the operation state of the ion generation unit 100, and the cover 10. The microswitch 351 for detecting the open / closed state of is provided. The display LED 437 is composed of a first blue LED, a second blue LED, a red LED, and a green LED, and changes the color in accordance with the operation state of the ion generation unit 100 to display the LED. Further, the user is warned about the replacement time of the ion generation unit 100 and a filter to be described later by lighting the display LED 437.
The ion generating element A31 is a rectangular plate-like body, has a positive ion generating electrode part (electrode needles 31a, 31b) as an electrode part for generating positive ions in the vicinity of one end, and in the vicinity of the other end. Have negative ion generation electrode portions (electrode needles 31c and 31d) as electrode portions for generating negative ions. The positive ion generating electrode portion (electrode needles 31a and 31b) and the negative ion generating electrode portion (electrode needles 31c and 31d) are separated from each other, and the positive ion generating electrode portion is in the air with the ion generating element A31 attached to the side surface 45. The negative ion generating electrode portion is arranged in the vicinity of the air outlet 14 (blowout hole 24) in the vicinity of the outlet 11 (blowout hole 21).

With the above configuration, air containing positive ions and negative ions can be blown out independently from different air outlets. Therefore, it is possible to prevent the positive ions and the negative ions from being combined immediately after the generation, and to release the positive ions and the negative ions to the outside immediately after the generation, so that it is possible to diffuse further.
The ion generating element B32 has the same configuration as the ion generating element A31, and generates negative ions in the vicinity of the air outlet 12 (the outlet hole 22) in a state where the ion generating element B32 is attached to the inclined surface. A negative ion generating electrode part is disposed, and a positive ion generating electrode part for generating positive ions is disposed in the vicinity of the air outlet 13 (blowout hole 23). Therefore, air containing negative ions is blown out from the air outlet 12, and air containing positive ions is blown out from the air outlet 13.

In the configuration described above, the ion generating element A31 and the ion generating element B32 are arranged so that the positive ion generating electrode part and the negative ion generating electrode part are diagonal to each other. With this arrangement, it is possible to release positive ions and negative ions into the outside air in a well-balanced manner.
Further, the ion generating element A31 and the ion generating element B32 ionize water vapor in the air by plasma discharge, thereby generating H ⁺ (H ₂ O) _m (m is an arbitrary natural number) as positive ions and negative ions. O ₂ ⁻ (H ₂ O) _n (where n is an arbitrary natural number). The generated H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n adhere to airborne bacteria, airborne viruses, etc. in the air and chemically react with hydrogen peroxide (H ₂₎ which is an active species. O ₂ ) and / or hydroxyl radicals (OH) are generated. Since H ₂ O ₂ and / or OH shows extremely strong activity, it is possible to surround and remove adhering airborne bacteria and airborne viruses.

  The suction grill 20 is provided with a suction hole 25 in the center, and is provided with four outlet holes 21, 22, 23, 24 around the suction hole 25. Further, as shown in FIG. 5, a ventilation wall 201 having an inclined surface 201 a for forming a ventilation path for air sucked from outside together with the bottom surface and the side surface of the main body base 30 on the back surface side facing the main body base 30. Two are provided across the suction hole 25. The height of the ventilation wall 201 is set to be lower than the depth of the main body base 30, and the inclination angle of the inclined surface 201 a of the ventilation wall 201 is substantially the same as the inclination angle (45 °) of the side surface of the main body base 30. Thus, a ventilation path can be secured between the ventilation wall 201 and the bottom surface and the side surface 45 of the main body base 30.

In addition, a ventilation plate 202 is provided at the center of each ventilation wall 201 and functions as a partition plate for partitioning positive ions and negative ions so that the ion generating elements A31 and B32 are attached. Yes. The ventilation plate 202 has inclined surfaces 202 a and 202 b, and air flowing in collision with the throttle portion 37 of the main body base 30 can be distributed to the respective blowing holes and smoothly blown. Furthermore, the blowing holes 22 and 24 provided in the diagonal position are provided with the baffle plate 204, and can blow out in the direction different from the other blowing holes 21 and 23. FIG. Accordingly, the air blown out from the blowout holes 21, 22, 23, and 24 are all in different directions, so that positive ions and negative ions can be diffused in a balanced manner.
Therefore, the ventilation wall 201, the ventilation plate 202, and the rectifying plate 204 each form a part of an air ventilation path, and also have a function as a blowing direction setting member that sets an air blowing direction.

The cover 10 is attached to the opening of the case 40 so as to cover the main body base 30 and the suction grille 20 from the front, the air suction port 15 for sucking outside air into the main body base 30, and the ion generating element. Air outlets 11, 12, 13, 14 for blowing out air containing ions generated from the. The air inlet 15 is disposed at a position corresponding to the suction hole 25 of the suction grill 20, and the air outlets 11, 12, 13, 14 are positions corresponding to the outlet holes 21, 22, 23, 24 of the suction grill 20, respectively. Is arranged.
Further, each of the blowout holes 21, 22, 23, and 24 has a slit made of a plurality of partition plates that are inclined along the air blowing direction. By inclining the partition plate along the blowing direction, the blowing direction can be determined more reliably in addition to the above-described blowing direction setting member of the suction grill 20. Therefore, since air containing ions can be diffused in four different directions, airborne bacteria and viruses in the room can be reliably removed.

Further, on the side of the cover 10 facing the suction grill 20, the protruding bar 16 is provided at a position corresponding to the micro switch 351 provided on the outer surface of the main body base 30. When the cover 10 is closed with respect to the case 40 (suction grill 20) (closed state), the protruding rod 16 functions as a pressing portion and presses the micro switch 351 as the pressed portion. Further, in a state where the cover 10 is open (open state), the protruding bar 16 does not press the microswitch 351 and the two are separated. With the above configuration, it is possible to detect the open / closed state of the cover 10 by detecting whether the microswitch 351 is pressed. The microswitch 351 and the protruding bar 16 constitute a set of switches as detection means for detecting the open / closed state of the cover 10.
Further, a filter (not shown) for removing dust contained in the air sucked into the inside of the ion generation unit 100 from the outside is provided on the back side of the air suction port 15 of the cover 10.

FIG. 6 is a main block diagram of the illumination device of FIG. Connection and control of each unit constituting the lighting apparatus will be described with reference to FIG.
The lighting device 200 converts AC power supplied from the outside into a constant current and supplies it to each unit such as the light source unit 411 having the LED module 203, and receives a constant current from the power supply unit 401. The light source unit 411 that emits light, the ion generation unit 100 that is driven by receiving a constant current from the power supply unit 401, and the light source unit 411 and the ion generation unit 401 that are supplied with a constant current from the power supply unit 401 are individually controlled. The control unit 421 is configured.
The power supply unit 401 is a power supply unit that converts an AC external power supply into a constant current power supply, and includes a protection circuit 402, a rectifier circuit 403 that performs full-wave rectification of the AC, a noise filter circuit 404 that removes noise, and an LED module.

It comprises a constant current control circuit 406 for making a constant current.

The light source unit 411 has a plurality of LED modules 203 as light source modules. Since the driving voltage of the LED module 203 is 33V, the constant current supply circuit 407 is set to be a constant current 33V power source.
The control unit 421 steps down the microcomputer 423 as a control unit for controlling the light source unit 411 and the ion generation unit 100, and the 33V power source supplied from the constant current supply circuit 407 to the drive voltage (5V) of the microcomputer 423.

FIG. 7 is a control flow diagram for displaying an ion generation unit and filter replacement sign of the illumination device of FIG. FIG. 8 is a control flow diagram when the filter of the lighting device of FIG. 1 is replaced.
The control for displaying the ion generation unit 100 and the filter replacement sign of the illumination device 200 will be described with reference to FIG.
When the illumination device 200 is turned on (S0), first, the microcomputer 423 reads the accumulated time of use of the ion generation unit 100 and the filter stored in the memory 424 until the previous final drive (S1).

Next, it is determined whether or not the ion generation unit 100 is currently driven (S2). When the ion generation unit 100 is not driven, it is not necessary to integrate the use time of the ion generation unit 100 and the filter, and thus the control flow for displaying the exchange sign is ended (S8).
When the ion generation unit 100 is driven, the usage time of the ion generation unit 100 and the filter is counted using a timer built in the microcomputer 423 (S3). The usage time is counted by driving the ion generation unit 100 at predetermined time intervals (in units of 10 minutes). Specifically, it is determined whether or not the driving of the ion generation unit 100 is continued for 10 minutes (S4), and the accumulated use time of the ion generation unit 100 and the filter stored in the memory 424 is set to 10 every 10 minutes. Update by increments of minutes (S5). If the ion generation unit 100 is not continuously driven for 10 minutes, for example, while the usage time is being counted, it is not updated during the in-use integration in the memory 424.

Next, it is determined whether the accumulated usage time of the ion generation unit 100 and the filter has reached a predetermined replacement time stored in the memory 424 (S6). If the replacement time has not been reached, the usage time is counted according to the control flow as long as the driving of the ion generation unit 100 is continued (S4). If the replacement time has been reached, the user is warned by displaying an exchange sign on the display unit 36 (S7). Thus, the control flow for detecting the ion generation unit 100 and the filter replacement time is completed (S8).
The replacement time of the ion generation unit 100 stored in the memory 424 is 20000 hours, and the replacement time of the filter is 1500 hours. If the ion generation unit 100 reaches the replacement time and continues to be used without being replaced, there is a state in which positive ions and negative ions are not released from the ion generation unit 100 (ion generation element A31 / ion generation element B32). As a result, a sufficient air cleaning function may not be exhibited.

Further, if the filter is not replaced, the filter is clogged with dust or the like, air is not sufficiently sent into the ion generating unit 100, and the amount of air containing ions blown to the outside is reduced. Therefore, the ability of the ion generating unit 100 to diffuse the air containing ions is reduced.
According to the control as described in the above control flow, the user can be surely visually informed of the replacement time by displaying the replacement sign on the display unit 36, so that the warning can be given. It is possible to prevent deterioration of the function.

Next, the control at the time of filter replacement of the ion generation unit 100 is demonstrated using FIG.
First, when the filter replacement operation is started (S10) and the cover 10 is opened for filter replacement, the cover open / close detection circuit 435 of the ion generation unit 100 changes from the pressed state of the microswitch 351 to the open state of the cover 10. Is detected (S11). When it is detected that the cover 10 is in the open state, a signal indicating that the cover 10 is in the open state is transmitted to the microcomputer 423 (S12), and the microcomputer 423 controls the ion generation unit 100 to stop driving (S13). More specifically, the microcomputer 423 transmits a signal for stopping the driving of the ion generating element A31, the ion generating element B32, and the fan 33 to the ion generating element driving circuit 433 and the fan driving circuit 434. Is stopped to stop driving. Since the driving of the ion generation unit 100 is stopped, the filter can be safely replaced.

After that, when the cover 10 is closed and the projection bar 16 of the cover 10 returns to the state of pressing the micro switch 351 again, the cover open / close detection circuit 435 detects the closed state of the cover 10 (S14). When it is detected that the cover 10 is in the closed state, a signal that the cover 10 is in the closed state is transmitted to the microcomputer 423 (S15), and the driving of the ion generation unit 100 is automatically restarted (S16).
When the filter is replaced, the above control is performed, and a safe filter replacement is possible (S17). Further, while the filter is being replaced, the driving of the ion generation unit 100 (the ion generation element A31, the ion generation element B32, and the fan 33) is stopped, but power is continuously supplied to the light source unit 411 of the lighting device 200. The light source unit 411 is driven and illumination is continuously performed. Therefore, since the filter can be replaced under illumination, the filter can be easily replaced.
Further, since the illumination device 200 is configured such that power is individually supplied to the light source unit 411 and the ion generation unit 100, the power source unit 411 is supplied with power even when the ion generation unit 100 itself is replaced. The ion generation unit 411 itself can be replaced under illumination.

FIG. 9 is a table for explaining the lighting state of the display LED of the display unit indicating the operation state of the ion generation unit of FIG. 2 and the display of the replacement time of the filter and the ion generation unit. The lighting states of the plurality of display LEDs 437 are shown for each operation state of the ion generation unit 100 described in the first column of the table.
The ion generation unit 100 has a plurality of operation modes (high mode, middle mode, low mode) in which the rotation speed of the fan 33 is different, and can be selected by a user with a remote controller or the like. By changing the rotational speed of the fan 33, the ion concentration in the room can be adjusted. For example, when the indoor air purifying function is to be strengthened, the high-mode is set and the ion generating unit is driven to drive the fan. By increasing the rotation speed, the ion concentration in the room can be increased and the air cleaning function can be strengthened. The low mode is the mode in which the number of rotations of the fan is the smallest, and the air cleaning capability is the smallest in these three modes. The middle mode is an intermediate level between the high mode and the low mode.

In addition, the display unit 36 is turned on by combining a plurality of display LEDs 437 so as to have different colors for each of the plurality of modes. The lighting of the display LED 437 is controlled by transmitting a signal about the mode from the microcomputer 423 to the display LED drive circuit 436, and the display LED drive circuit 436 is performed according to the signal.
As shown in FIG. 9, the first blue LED and the second blue LED are used in the high mode, the second blue LED and the green LED are used in the middle mode, and the second blue LED is used in the low mode. Light up. The reason why the colors are different from each other is that it is difficult for the user to determine in which mode the ion generating unit being driven is driven because the ions emitted into the room cannot be visually recognized.
Further, the red LED is turned on when displaying the replacement sign of the filter replacement time, and the second blue LED and the green LED are blinked when displaying the replacement sign of the replacement time of the ion generating unit.

As described above, since the user can visually recognize the replacement time, the function of the ion generation unit 100 can be prevented from being lowered and continuously used in the state.
In addition, the combination of the colors of the LED 437 for display when displaying the operation state of the ion generation unit 100 and the replacement time of the filter and the ion generation unit 100 described above is an example. Moreover, you may use LED203a of the light source unit 411 as LED for display as a structure which can change the color of LED module 203 of the light source unit 411, or some LED203a of LED module 203. FIG. Since there is no need to separately provide a display LED, the cost of the lighting device can be reduced.

  Next, control for resetting the lighting display of the display LED 437 that displays the replacement time of the ion generation unit 100 and the filter will be described. The filter replacement time is displayed with the red LED continuously lit even when the ion generation unit 100 is stopped, and the replacement time of the ion generation unit 100 is indicated by the second blue LED and the green LED. Since it is performed by blinking, there is a possibility that the user may feel uncomfortable. Therefore, the illuminating device 200 has control which resets the lighting display of the exchange sign of each of the ion exchange unit 100 and a filter.

FIG. 10 is a control flow diagram for resetting the lighting display of the display LED that displays the replacement time of the ion generation unit and the filter.
As shown in FIG. 10, when resetting the lighting display of the display LED 437 that displays the replacement time of the ion generation unit 100 and the filter (S <b> 20), first, the cover 10 provided on the front side of the ion generation unit 100. It is necessary to remove. When the cover open / close detection circuit 435 detects that the cover 10 has been removed and is in an open state (S21), it controls the ion generation unit 100 to stop driving and stop driving the ion generation unit 100 (S22). . Note that the detection of the open state of the cover 10 is performed when the cover open / close detection circuit 435 detects the pressing state of the microswitch 351 as described above. Once the cover 10 is opened, if the filter replacement sign is displayed, the cover 10 is turned off and the accumulated filter use time is cleared (S25).

Next, it is determined whether or not the sign displayed on the display unit 36 is an exchange sign for the ion generation unit (S24). If it is an exchange sign for the ion generation unit 100, the cover open detection flag is set in the memory 424 (S25), and if it is not an exchange sign for the ion generation unit 100, the cover open detection flag is not set.
Further, when the cover 10 is closed and the cover open / close detection circuit 435 detects the cover closed state (S26), the driving of the ion generating unit 100 is resumed (S27). Further, it is determined whether or not there is a display reset signal from the external remote controller (S28). If there is no display reset signal, the user does not want to reset the display, so the exchange sign is continuously displayed (S32).
When the display reset signal is received, the filter replacement sign display is turned off, and the filter usage time accumulated time stored in the memory 424 is cleared (S29). Further, when the cover open detection flag is set in the memory (S30), the display of the exchange sign of the ion generation unit 100 is turned off and the ion generation unit use accumulated time stored in the memory 424 is cleared (S31). ). Thereafter, the control is terminated (S32).

  According to the above control, the filter replacement sign is displayed either when the cover 10 is opened once or when a display reset signal is received from the remote controller. The display of the exchange sign is reset only when both the opening and closing of the cover 10 and the reception of the display set signal from the remote controller are received. That is, many conditions are set in the reset display of the exchange sign of the ion generation unit 100 as compared with the reset display of the filter exchange sign.

(Embodiment 2)
FIG. 11 is a schematic perspective view of the illumination device according to the second embodiment of the present invention. About the same part as Embodiment 1, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.
Illuminating device 300 of Embodiment 2 is a rectangular parallelepiped (straight type) illuminating device, and is a casing 302 having a bottom surface made of aluminum having a rectangular shape. A diffusion plate is attached to the opening of the housing 302, and the ion generation unit 100 is attached to one end on the short side of the housing 302.
Since the illumination device 300 is also controlled in the same manner as the illumination device 200 of the first embodiment, ions are generated when the ion generation unit 100 is removed for replacement or the cover 10 is opened to replace the filter. Even when the driving of the unit 100 is stopped, it is possible to continue illumination by supplying power to the light source unit 411. Therefore, the ion generation unit 100 and the like can be easily replaced under illumination.

In the above description, the case where the ion generation unit is not driven is illustrated as an example of replacement of the ion generation unit. However, since the electric device and the light source can supply power from different systems, ion generation can be performed. Even when the power of the unit 100 is turned off and the driving is stopped, it is possible to supply power only to the light source and continue the illumination. Therefore, the user can arbitrarily select on / off of the power supply of the ion generation unit 100 at the time of illumination.
In the above description of the embodiment, the ion generation unit (ion generation device) is exemplified as the electric device attached to the lighting device, but the present invention is not limited to this. For example, other electric devices such as an air conditioner may be used.
Furthermore, although LED is used as a light source of a light source unit, it is not limited to this, Other light sources, such as a fluorescent lamp and EL (Electro-Luminescence), may be sufficient. Further, although a high color rendering LED is used as the LED, a pseudo white LED made of a blue LED and a yellow phosphor may be used, and a package LED made of a red LED, a green LED, and a red LED. There may be.
