Description

TECHNICAL FIELD [0001] The present invention relates to an indoor lighting apparatus having an air purifying function,

The present invention relates to a lighting apparatus, and more particularly, to an indoor lighting apparatus having an air purifying function for removing contaminants such as smoke, odor and dust generated in a room such as a dining table, kitchen, living room, And more particularly to a filter change alarm method thereof.

In recent years, the proportion of use of LEDs (Light Emitting Diodes) which can obtain a high illuminance with a semi-permanent life and a low power instead of conventional incandescent lamps or fluorescent lamps has been increasing as a light source of a lighting apparatus. As a result, LED lighting devices of various products are continuously supplied to the market. Such an LED illumination device is merely performing a primary illumination function to provide light in the dark.

However, indoor air pollution due to buildings and furniture made of various harmful substances such as air pollution and formaldehyde due to soot has recently become serious. In the process of cooking or eating food in home kitchens, dining tables, and living rooms, a large amount of contaminants such as smoke, odor, and dust are generated. In addition, the health of residents is threatened by various bacteria and microorganisms present in the room.

Accordingly, air purifiers, sterilization apparatuses and ventilation apparatuses are separately purchased and used in ordinary households or offices.

However, the purchase and use of the air purifying device, the sterilizing device, and the ventilating device separately may cause an increase in the purchase cost and a large installation space.

Accordingly, in order to solve such a problem, an indoor lighting device having an air purifying function together with a lighting function has been introduced. Such a lighting device has a built-in filter that performs an air purifying function.

Filters built in the lighting device have to be replaced periodically, which is troublesome because the user has to remember and replace the filter replacement cycle. If the user misses the replacement cycle of the filter, the problem of the air purifying function deteriorates. On the contrary, it is possible to consider a method of exchanging the actual filter shorter than the service life of the actual filter. However, in this case, a problem arises that the filter that can be used is wasted.

Also, since the pollution degree differs depending on the indoor place where the lighting device is installed and the use time may be different, the replacement period of the filter may also be different from each other. However, it is not practical for the user to exchange the filter considering the replacement period of the filter considering the indoor place where the lighting device with the built-in filter is installed.

In addition, since the conventional indoor lighting device having the air purification function is fixed to the ceiling and fixedly used, it is difficult to adjust the height, so that it can not effectively purify the air when it is used in a place where the height adjustment is required . That is, when food is cooked directly at the table, the use of the lighting device close to the place where the food is cooked can effectively purify the substance generated in the process of cooking the food. On the other hand, when viewing a book or a newspaper at the table or communicating, it is preferable to place the lighting device at a relatively high position as compared with the case where food is served. However, such a requirement can not be satisfied when a lighting apparatus is fixedly installed as in the prior art.

In a conventional indoor lighting device having an air purifying function, since the cable is exposed to the outside in the case of hanging on the ceiling, there is a problem that the cable exposed to the outside is easily contaminated by the external environment and is not good in appearance.

In the following description, only parts necessary for understanding embodiments of the present invention will be described, and descriptions of other parts will be omitted to the extent that they do not disturb the gist of the present invention.

The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings and the inventor is not limited to the meaning of the terms in order to describe his invention in the best way. It should be interpreted as meaning and concept consistent with the technical idea of the present invention. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely preferred embodiments of the present invention, and are not intended to represent all of the technical ideas of the present invention, so that various equivalents And variations are possible.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view showing a state in which an indoor lighting device having an air purifying function is installed on a kitchen table according to an embodiment of the present invention.

1, an interior lighting apparatus 100 according to an embodiment of the present invention includes a fixture 10 having a process purification function and a controller 90 for controlling the driving of the fixture 10 .

The illuminator 10 includes an illumination module 50 that performs an illumination function to adjust the brightness around the table 120 so that the air sucked by the fan 30 is supplied to the plurality of filters 40 After passing through, it is purified and exhausted to the outside. At this time, the illuminator 10 has a form in which the fan 30, the filter 40 and the lighting module 50 are embedded in the case 20, and the upper part of the case 20 passes through the filter 40, An air vent hole 23 for discharging air is formed. That is, the illuminator 10 is provided with a fan 30, a plurality of filters 40 and an illumination module 50 inside the case 20, and a plurality of A filter (40) is installed below the fan (30). The illuminator 10 is provided with a communication module 60 provided in the case 20 and provided with an illumination module 50 around a plurality of filters 40. [

The controller 90 controls the driving of the lighting module 50 and the fan 30 of the illuminator 10 and stores the accumulated amount of rotation by counting the amount of rotation of the fan 30, When the set rotation amount is reached, the switching periods of the plurality of filters 40 are alarmed. The controller 90 may be a communication terminal capable of transmitting a control signal through communication with the communication unit 60 of the illuminator 10, for example, a dedicated remote controller, a smart phone, a tablet, or the like, but is not limited thereto.

In the present embodiment, the example in which the indoor lighting device 100 is installed on the ceiling 110 on the dining table 120 is described, but the present invention is not limited thereto. The indoor lighting device 100 has disclosed an example in which the air generated by the food 130 placed on the table 120 and the surrounding air are sucked and cleaned. The illuminator 10 is mounted on the ceiling 110 so as to be vertically adjustable via a ceiling mount 70 installed on the ceiling 110 and a connection tube 80 connected to the ceiling mount 70. [ do.

The controller 90 according to this embodiment will now be described with reference to FIGS. 1 and 2. FIG. 2 is a block diagram showing a detailed configuration of the controller 90 of FIG. 1

1 and 2, the controller 90 includes a transmission / reception unit 93, an input unit 91, a storage unit 95, an alarm unit 97, and a control unit 99.

The transmission / reception unit 93 communicates with the communication unit 60 of the illuminator 10. The transmission and reception unit 93 transmits a control signal for controlling the operation of the fan 30 or the lighting module 50 to the communication unit 60 of the illuminator 10 under the control of the control unit 99. [ The transceiver unit 93 can use a short-range communication scheme as a communication scheme. For example, the short distance communication method may be infrared communication, Bluetooth communication, Zigbee communication method, and the like, but is not limited thereto.

The input unit 91 transmits a selection signal inputted from a user, for example, a signal inputted in relation to various function setting and function control of the illuminator 10, to the control unit 99. As the input unit 91, a keypad, a touch pad, a touch screen, or the like may be used, but the present invention is not limited thereto.

The storage unit 95 stores a program necessary for controlling the operation of the illuminator 10 and information generated during the execution of the program. In particular, the storage unit 95 stores an execution program for monitoring and alarming the replacement cycle of the plurality of filters 40. [ The storage unit 95 stores the set amount of rotation that is a reference of the replacement period of the plurality of filters 40. [ The storage unit 95 stores the cumulative amount of rotation of the fan 30 under the control of the control unit 99. [ When the reset signal is inputted through the input unit 91, the storage unit 95 resets the accumulated amount of rotation according to the control of the control unit 99. [

At this time, the set amount of rotation is set based on the cumulative amount of rotation of the fan 30 corresponding to the replacement period of the plurality of filters 40. That is, since the plurality of filters 40 perform the function of purifying the air by the operation of the fan 30, the replacement period of the plurality of filters 40 is correlated with the operation time and the operation speed of the fan 30 . At this time, the rotation amount of the fan 30 can be calculated by multiplying the operation time of the fan 30 by the operation speed. Or the rotation amount of the fan 30 may reflect only the operation time of the fan 30. [ For example, when the rotation amount of the fan 30 only considers the operation time of the fan 30, the operation speed of the fan 30 may be one, or there may be a case where there is not a large variation even if the operation speeds are plural.

In addition, the set amount of rotation can be set together with the predetermined amount of time in addition to the amount of cumulative rotation due to use of the fan 30. [ The reason why the predetermined period of time is set together with the set amount of rotation is that the plurality of filters 40 are exchanged when the amount of use of the fan 30 is low and the predetermined amount of rotation can not be satisfied. Since the filter 40 may be deteriorated in filter performance over time, it is preferable that the filter 40 is replaced after a predetermined period of time elapses. The predetermined period may be set in consideration of the service life of the filter 40.

In the present embodiment, the set rotation amount includes the first rotation amount and the second rotation amount. At this time, the first full amount is a time point for outputting a preliminary alarm informing the replacement period of the plurality of filters 40. [ The second whole quantity is a time point for outputting a main alarm informing the replacement cycle of the plurality of filters 40. [ Of course, the second rotation amount is set longer than the first rotation amount. The first and second rotation amounts may be set in a default form or may be set according to a user's selection signal through the input unit 91. [ For example, the first and second rotation amounts may be set to 800 hours and 1000 hours based on the operation time of the fan 30. When the cumulative operation time (cumulative rotation amount) of the fan 30 reaches 800 hours (first rotation amount), the controller 90 outputs the preliminary alarm. When the cumulative operation time (cumulative rotational amount) of the fan 30 reaches 1000 hours (second rotational amount), the controller 90 outputs the main alarm.

In the present embodiment, the first and second rotation amounts are set at the set rotation amounts for the following reasons. It is possible to provide a spare filter 40 that can be exchanged by the user. However, in order to give the user a time to purchase the replaceable filter 40 when the extra filter 40 is not provided, In the example, the first rotation amount for outputting the preliminary alarm is set before the main alarm is output.

As described above, in the present embodiment, an example of outputting the preliminary alarm and the main alarm is described. However, it is also possible to set the alarm to be output only once, or to set the amount of rotation to output the alarm three or more times.

The alarm unit 97 outputs an alarm when the period of replacement of the filter 40 is reached under the control of the control unit 99. The alarm unit 97 can output an alarm using sound, light, vibration, or the like. At this time, in this embodiment, the example in which the alarm unit 97 is installed in the controller 90 is described, but the present invention is not limited to this. The alarm unit 97 may be installed in the illuminator 10 or installed in the controller 90 and the illuminator 10, respectively. Light emitted from the lighting module 50 of the illuminator 10 can be used for alarming. For example, when the illuminator 10 receives the control signal according to the alarm through the controller 10, the LED of the illumination module 50 is blinked to notify the user of the replacement period of the filter 40. [

The control unit 99 is a microprocessor that performs overall control operations of the controller 90 and the illuminator 10 and provides various control signals for controlling the illuminator 10. The control unit 99 controls the illumination function of the illuminator 10 and the air purifying function through the plurality of filters 40 according to the operation of the fan 30. [

The control unit 99 according to the present embodiment monitors an exchange period of a plurality of filters 40 and controls an alarm for an exchange period of the plurality of filters 40. [ That is, the control unit 99 transmits a control signal for controlling the operation of the fan 30 and the lighting module 50 to the illuminator 10 through the transmission / reception unit 93. The control unit 99 counts the amount of rotation of the fan 30 and stores the accumulated rotation amount. When the stored accumulated rotation amount reaches the set rotation amount, the control unit 99 outputs an alarm indicating the replacement period of the plurality of filters 40 to the alarm unit 97 .

For example, when the set rotation amount is the first rotation amount and the second rotation amount, the control unit 99 can perform the alarm of the replacement period of the filter 40 as follows. That is, when the stored cumulative amount of rotation reaches the first rotational amount, the control unit 99 outputs a preliminary alarm for notifying the replacement period of the plurality of filters 40 through the alarm unit 97. The control unit 99 controls the main alarm to be output through the alarm unit 97 when the stored accumulated rotation amount exceeds the first rotation amount and becomes the second rotation amount. On the other hand, if a reset signal is inputted through the input unit 91 after one of the preliminary alarm and the main alarm is outputted, the control unit 99 resets the cumulative amount of rotation of the fan 30 to reset the amount of rotation of the fan 30 Count.

As described above, according to the present embodiment, the controller 90 counts the rotation amount of the fan 30 to store the accumulated rotation amount, and alarms the replacement period of the plurality of filters 40 when the accumulated rotation amount reaches the set rotation amount, It is possible to inform the user of the replacement time of the filter 40 and to guide the replacement of the filter 40 according to the replacement period of the filter 40. [ Therefore, even if the user does not separately memorize the exchange periods for the plurality of filters 40, after the user recognizes the preliminary alarm or the main alarm output from the controller 90, the user can easily perform the exchange with respect to the plurality of filters 40 .

The illuminator 10 according to the present embodiment will now be described with reference to FIGS. 3 to 8. FIG. Figures 3 and 4 are perspective views showing the illuminator 10 of Figure 1. 5 is a cross-sectional view of the illuminator 10 of FIG. 6 and 7 are perspective views showing a state in which the length of the connecting pipe 80 of the illuminator 10 of FIG. 1 is extended.

For example, the case 20 is formed in a dome shape having an internal installation space, and a plurality of air discharge holes 23 are formed in a discontinuous concentric shape in the horizontal direction on the dome. The air discharge hole 23 formed in the horizontal direction discharges the air discharged by the fan 30 in the horizontal direction.

The fan 30 is installed in the upper part of the case 20 and sucks the air through the lower part of the case 20 and discharges the air through the air discharge hole 23 of the case 20. The fan 30 is installed close to the air discharge hole 23 so that air can be smoothly discharged through the air discharge hole 23.

The plurality of filters 40 are provided inside the case 20 and are detachably installed in the vertical direction under the fan 30 to purify the air sucked in accordance with the driving of the fan 30. [ A filter housing 49 may be installed in the case 20 to facilitate the detachment of the plurality of filters 40. The plurality of filters 40 may include a plate filter 41, an oil removing filter 43, a deodorizing filter 45, and a deodorizing filter 45, which are sequentially installed inwardly from the bottom of the case 20.

[ The plate filter 41 is detachably attached to the opening of the case 20. For example, the plate filter 41 may be detachably attached to the filter housing 49 located at the opening of the case 20. [

The deodorizing filter 43, the deodorizing filter 45, and the deodorization filter 45 may be stacked in this order from the bottom in the filter housing 49.

The deoiling filter 43 is in the form of a plate having a plurality of fine holes, and primarily filters the oil components contained in the air. As the deaeration filter 43, a punching type, a cut bend type, a net type, a non-woven type, etc. in which a plurality of holes are formed in a metal or plastic material may be used, but the present invention is not limited thereto. The deoiling filter 43 may be detachably installed in the filter housing 49 above the plate filter 41.

The deodorizing filter 45 is a filter for removing the smoke. The deodorizing filter 45 may be installed on the deodorizing filter 43 in a stacking manner. For example, a HEPA (High Efficiency Particulate Air) filter may be used as the deodorization filter 45, but the present invention is not limited thereto.

The deodorization filter 45 removes the odor contained in the sucked air. The deodorization filter 45 may be installed on the deodorizing filter 45 in a laminated manner. The deodorization filter 45 includes activated carbon having a deodorizing function. The finally purified air passing through the deodorization filter 45 passes through the fan 30 and is discharged to the outside through the air discharge hole 23 of the case 20. [

The lighting module (50) is installed around the plurality of filters (40). The lighting module 50 may include an LED substrate 51, an LED power supply 53, and a diffusion plate 55.

The LED substrate 51 includes a plurality of LEDs for outputting light that directs illumination through the opening 21 of the case 20. [ The plurality of LEDs are disposed in a space exposed between the plate filter 41 and the case 20 to output light to the outside through a portion of the opening 21 exposed to the outside of the plate filter 41. The LED substrate 51 includes an LED driving driver for processing a control signal transmitted through the communication unit 60. The LED driving driver adjusts brightness and color through driving control of a plurality of LEDs, thereby making it possible to produce various lights. The LED driving driver may control the driving of the fan 30 according to a control signal input through the communication unit 60. [

The LED power supply unit 53 receives power from the outside and converts the power into a power required for LED driving. As the LED power supply unit 53, a switching mode power supply (SMPS) may be used.

The diffusion plate 55 is formed to cover the open portion 21 of the exposed case 20 outside the plate filter 41 and functions to diffuse light output from the LED substrate 51. The diffusion plate 55 is detachably installed between the plate filter 41 and the case 20.

The communication unit 60 is installed in the case 20 and communicates with the transmission / reception unit 93 of the controller 90. [ The communication unit 60 uses a short-distance communication method as a communication method. The communication unit 60 receives a control signal for controlling the operation of the fan 30 or the lighting module 50 from the controller 90 and transmits the control signal to the lighting module 50 and the fan 30.

If the determination result in step S21 is not satisfied, the controller 90 performs step S10.

If the determination result in step S21 is reached, the controller 90 outputs a preliminary alarm through the alarm unit 97 in step S23.

Next, in step S25, the controller 90 determines whether or not a reset signal is input through the input unit 91. [

If the result of the determination in step S25 is YES, the controller 90 resets the accumulated rotation amount of the fan 30 in step S35. Then, the controller 90 performs step S10.

If the result of the determination in step S25 is negative, it is determined in step S27 whether the accumulated rotation amount of the fan 30 has reached the second rotation amount.

If the determination result in step S27 is not satisfied, the controller 90 counts and accumulates the amount of rotation of the fan 30 in step S29, and then proceeds from step S25 again.

If the determination result in step S27 is reached, in step S31, the controller 90 outputs the main alarm via the alarm unit 97. [

In step S33, the controller 90 determines whether a reset signal has been input through the input unit 91 or not.

If the result of the determination in step S33 is YES, the controller 90 resets the accumulated rotation amount of the fan 30 in step S35. Then, the controller 90 performs step S10.
