Lighting Appliance having Indoor Air Quality Display Function

The present design allows the cleanliness of indoor air to be accurately recognized in real time even without looking at a specific direction or fixing the gaze in a specific direction, and an indoor cleanliness display function to intuitively recognize the quality of indoor air. It is about.

As is well known, indoor air in various stores, such as homes, offices, and department stores, is often contaminated due to various factors.

In particular, in homes that do not have an air purifier with sufficient performance, offices with large spaces, and various stores, possible measures such as ventilation are taken by a person's intuitive feeling. However, since human intuition is not objective, there is a problem in that it is not possible to ventilate in an appropriate situation. In order to solve this problem, a remote control or a television equipped with a means for measuring the degree of air pollution has been proposed.

First, looking at the Korean patent registration 10-1722389 (the name of the invention: a two-way RF remote control equipped with an indoor air sensor; hereinafter referred to as'cited draft 1') that allows the indoor air pollution level to be measured using a remote control, the above cited draft 1 relates to a two-way RF remote control equipped with an indoor air detection sensor, a remote control that communicates RF through a TV or set-top box (STB) and an RF communication module, and the remote control is integrated with the remote control. Air pollution detection means for detecting air pollution in the placed space, as a result of comparing the air pollution detected by the air pollution detection means and a preset air pollution reference value in a state integrally coupled to the remote control, detected by the air pollution detection means Air pollution determination means for transmitting a warning message indicating that air is polluted to the TV or set-top box through the RF communication module when the air pollution level exceeds a preset air pollution standard value, and the TV or set-top box is an air pollution determination means When a warning message indicating that the air is polluted is input from, a pop-up window with a warning message indicating that the air is polluted is displayed on the screen to indicate that the air is polluted. The air pollution level detected by the air pollution detection means is transmitted to the TV or set-top box through the RF communication module so that the air pollution level detected by the air pollution detection means is displayed on the TV screen.

Therefore, this reference draft 1 has a problem that the TV must be turned on and watched in order to know the current indoor air pollution status, and a remote control with built-in air pollution detection means must be provided in a place where pollution measurement is possible.

As another form, Korean Patent Publication No. 10-2006-01277712 (title of the invention: a television measuring indoor air pollution level; hereinafter referred to as'cited draft 2') has been proposed. The reference proposal 2 includes: a light-emitting unit installed on one side of a front side of a television to emit light; and a light-receiving unit installed opposite the light-emitting unit to have a measurement area therebetween to detect light emitted from the light-emitting unit; An ADC that converts an electrical signal according to the amount of light received by the light receiving unit; A processing unit configured to receive a signal converted from the ADC to detect a degree of dust pollution and to determine whether ventilation is necessary by comparing the detected degree of dust pollution with a preset ventilation reference value; And an On Screen Display (OSD) for displaying a result detected from the processing unit and whether ventilation is necessary.

Therefore, according to the above, cited draft 2 is expected to be effective in purifying the indoor air by inducing ventilation to the user watching the television screen. Therefore, in order to know the degree of indoor air pollution, such a reference plan 2 also has the inconvenience of having to turn on and watch the TV.

As can be seen from this, the present invention includes a lighting LED 102 and a diffusion plate 103 inside the frame 100, and a hanger 104 and a power supply 105 above the frame 100. But,

A fine dust sensor 301 and a harmful gas sensor 302 are mounted above the light guide plate 403 mounted at a position lower than the hanger 104,

It includes an air cleanliness detection means composed of the fine dust sensor 301 and the harmful gas sensor 302, and inputs the output of the air cleanliness detection means to the driving unit 400, and the driving unit 400 sets the A light guide plate 403 is installed around the display LED 201 while driving the display LED 201 assembled on the display PCB 200 by comparing the signal of the air cleanliness detection means with the reference level. The edge 404 of the light guide plate located outside the light guide plate 403 is arranged around the frame 100.

In this design, power is supplied to the power supply 105 installed in the hanger 104 by turning the switch "on" in the same way as a general lighting lamp, and the power supply 105 rectifies and depressurizes the SMPS method. Since the DC power is supplied to the lighting LED 102 of the lighting PCB 101, the emitted light is diffused to the outside through the diffusion plate 103, so that the main light of the lighting lamp (light that is lit from the lighting LED 102) is a lighting lamp. It illuminates the indoor space below, and the color light of the display LED 201 indicating the cleanliness of the indoor air depends on the cleanliness of the indoor air detected by the air cleanliness detection means regardless of whether the main light of the lighting is ON/OFF. The ceiling of the room where the lighting lamp is installed can be colored with color light, and the operation of displaying the air quality by means of the air cleanliness detection means and the display LED 201 is the indoor where the lighting lamp is installed according to the operation of the motion detection sensor included in the lighting lamp. Not only can it be configured to operate only when there are people in the room, but it also analyzes and analyzes the type of movement, frequency, position, and simultaneous movement through the motion detection sensor according to the number of people entering the room where the lighting lamp is installed. 401) automatically adjusts and sets the range of harmful gas standard data so that the sensitivity or display range of the indoor air cleanliness indication can be changed according to the number of people.

In particular, the present invention detects harmful gases stipulated in the indoor air quality inspection items such as TVOC (total volatile organic compounds), HCHO (formaldehyde), C6H6 (benzene) contained in indoor air, which are exemplified as air cleanliness detection means. The harmful gas sensor 302 and the fine dust sensor 301 for detecting the concentration of fine dust of 10 μm or less generate an output of a detection signal or data.

The outputs of the fine dust sensor 301 and the harmful gas sensor 302 are transmitted to the driving unit 400 installed below the hanger 104. The driving unit 400 is preferably built-in or external, and has a microcontroller unit 401 having a memory in which air cleanliness standard level data is stored, and a display LED 201 capable of emitting multicolor light that emits color light indicating air cleanliness. A driving unit 402 for driving the drive may be provided.

Therefore, the microcontrol unit 401 takes the air cleanliness standard level data for harmful gases and fine dust stored in the memory, and the harmful gas sensor data input from the harmful gas sensor 302 and the fine dust sensor 301, and A/D conversion of fine dust sensor data is compared, and the deviation is calculated.

In addition, the microcontrol unit 401 is completely independent from the daylight operation of the lighting lamp according to this deviation value (regardless of the ON/OFF of the lighting lamp), and a predetermined output to the display LED 201 operated as an independent operation. By applying, the display LED 201 may emit necessary color light. The display LED 201 may specifically be a multicolor LED having 4 terminals including a common terminal, and the multicolor LED includes R, G, B LEDs built into one package, and the driver 402 of the driving unit 400 ), the specific operation of the present invention may be performed according to the electrical configuration schematic diagram of FIG. 7 and the program flow diagram performed by the microcontrol unit 401 built in the driving unit 400 of FIG. 8. It will be described in detail as follows.

The present invention can display the indoor air quality by means of a three-color LED having three types of green, red, and yellow, for example, the display LED 201 in the manufacturing production stage. In this case, when the harmful gas concentration detected by the harmful gas sensor 302 is a value that is more than a certain high (hereinafter referred to as'hazardous gas upper limit data'), the display LED 201 is turned on in red, and a value that is less than a certain value ( In the case of hereinafter referred to as'lower limit data of harmful gas'), it is determined whether the display LED 201 is to emit green, and the data of the upper limit of harmful gas and the data of the lower limit of harmful gas are based on the air quality in the internal and external memory of the driving unit 400. It can be stored as level data.

In addition, according to the present invention, when the concentration of the fine dust detected by the fine dust sensor 301 is a certain or more high value (hereinafter referred to as'fine dust upper limit data'), the display LED 201 is turned on in red and is not less than a certain amount. In the case of a low value (hereinafter referred to as'fine dust lower limit data'), it is determined whether or not the display LED 201 is to emit green, and the fine dust upper limit data and the fine dust lower limit data accordingly are stored in the internal or external memory of the driving unit 400. It can be stored as air quality reference level data.

These internal or external memories are read and utilized by the microcontrol unit 401 of the driving unit 400.

That is, in the present invention, power is applied directly connected to the power line so that power is supplied together with the lighting PCB 101 or separately operated at all times, and the operation is started, and the microcontrol unit 401 of the lighting lamp is displayed at the initial stage of operation. After performing the initialization step 700 to check the connection status of 201) and the connection status of the internal and external memories, the harmful gas reference data consisting of the harmful gas upper limit data and the harmful gas lower limit data stored in the memory exist in the memory. Perform a determination step 701 of completion of the input of harmful gas reference data to determine whether or not,

When fine dust reference data input complete determination step 702 of determining whether fine dust reference data consisting of fine dust upper limit data and fine dust lower limit data exists in the memory is performed, and all are confirmed as normal inputs As long as, a harmful gas sensor input determination step 703 is performed to check whether a detection signal from the harmful gas sensor 302 is input.

In the present invention, the microcontroller unit 401 performs A/D conversion and storage step 704 of A/D conversion and storage of the output of such a harmful gas sensor 302, and digitized harmful gas sensor data is stored in a register. do.

In addition, the present invention performs a fine dust sensor input determination step 705 in which the microcontrol unit 401 checks whether a detection signal from the fine dust sensor 301 is input.

In the present invention, the microcontroller unit 401 performs an A/D conversion and storage step 706 of A/D conversion and storage of the output of the fine dust sensor 301 to store the digitized fine dust sensor data in a register. do.

Subsequently, the present invention performs an upper limit data abnormality determination step 707 to determine whether the currently input harmful gas sensor data is equal to or greater than the stored harmful gas upper limit data, and as a result, the harmful gas sensor data is harmful. In the case of more than the gas upper limit data, the driver 402 with a built-in switching element lights up in red by performing the display LED red lighting step 800, so that people in the room can pass through the edge 404 of the light guide plate configured around the ceiling lamp. Since the ceiling is in the range of the surrounding field of view even if the red light emitted from the red light covers the ceiling or does not look at the ceiling, the color light emitted through the edge 404 of the light guide plate and the change in color light can be recognized. In other words, by seeing these changes in light or light, you can feel intuition that the current indoor air is polluted, and you can take appropriate measures such as internal circulation ventilation and external air inflow ventilation.

In addition, when the indoor air pollution condition is eliminated by the inflow of outside air, external fine dust may be introduced, so even if the harmful gas sensor data is lowered below the harmful gas upper limit data in the above upper limit data determination step 707, input Since the fine dust sensor data may be higher than the stored fine dust upper limit data, the upper limit data abnormality determination step 708 is performed to determine whether the input fine dust sensor data is greater than or equal to the stored fine dust upper limit data.

As a result, when the fine dust sensor data is more than the fine dust upper limit data, the driver 402 lights the display LED 201 in red. By looking at the color of the light, you can feel intuition that the current indoor air is polluted, and even in this case, you can take appropriate measures such as internal circulation ventilation and air purifier operation.

In this way, when the indoor air is contaminated, the harmful gas concentration is performed by performing the above-described steps 707 to 708 by the input of the harmful gas sensor 302 and the input of the fine dust sensor 301, which are continuously updated by the above-described steps 703 to 706. When is high or the fine dust concentration is high, the display LED 201 is lit with a red light.In addition, when the indoor air pollution condition is resolved, it is determined whether the input harmful gas sensor data is lower than the stored harmful gas lower limit data. A lower limit data determination step 709 to be determined and a lower limit data determination step 710 to determine whether the input fine dust sensor data is lower than the stored fine dust lower data are performed.

In these determination steps (709, 710), the air quality is considered to be good only when it is determined that both the pollution level detected by the harmful gas sensor 302 and the concentration of the fine dust detected by the fine dust sensor 301 are lower than the lower limit. It can be determined, and only in this case, the display LED green lighting step 802 in which the display LED 201 is lit green is performed.

If the pollution level detected by the other harmful gas sensor 302 is lower than the harmful gas upper limit data but higher than the harmful gas lower limit data, the lower limit data is determined to determine whether the input harmful gas sensor data is lower than the stored harmful gas lower limit data. Immediately in step 709, the display LED yellow lighting step 801 is performed so that the display LED 201 is lit yellow,

In addition, even when the fine dust concentration sensed by the fine dust sensor 301 is lower than the fine dust upper limit data but higher than the fine dust lower limit data, it is determined whether the input fine dust sensor data is lower than the stored fine dust lower limit data. In the lower limit data determination step 710, the display LED yellow lighting step 801 is performed so that the display LED 201 is lit yellow.

In this way, the present invention makes it possible to recognize in real time the degree of indoor air pollution in real time, regardless of where in the room, even if a separate remote control or television is not operated or the monitor screen is not looked at.

In addition, the present invention shows an example of using the harmful gas sensor 302 and the fine dust sensor 301 exemplified as indoor air cleanliness detection means, but only one can be selectively applied as needed, and for convenience, the display LED Although the expression color of (201) is illustrated in three stages of green, red, and yellow, it is of course possible to express various colors by further subdividing them by driving in a PWM method.

In addition, in the electrical configuration shown in FIG. 8, the power of the driving unit 400 is supplied from the power supply 105 to achieve economic efficiency, but a separate power circuit may be configured and directly connected to the power line if necessary. have.

In addition, in the present invention, the color light representing the air cleanliness is limitedly emitted only at the edge 404 of the light guide plate 403 so that the color light emitted from the light guide plate 403 does not affect the light color of the lighting LED. The light blocking layer 405 was formed on the bottom of the light guide plate 403 to prevent the light of the display LED 201 from being mixed with the light of the lighting LED 102 and to make the irradiation direction different.

In addition, since the indoor resident only needs to recognize the color of the display LED 201 indicating air cleanliness, it is preferable that the light of the display LED 201 passes through the light guide plate 403 and is scattered at the edges. As shown, by forming a fine protrusion surface 406 on the edge 404 of the light guide plate, it is possible to improve the scattering property of color light emitted through the edge 404 of the light guide plate.

In this embodiment, since the light of the display LED 201 that has passed through the light guide plate 403 without loss in order to indicate the air cleanliness is scattered from the microprotrusions 406 and then is distinguished from the daylight of the lighting lamp and radiated to the atmosphere, a vivid color As a result, the current indoor air quality can be displayed.

In addition, in the present invention, since one or more fine dust sensors and harmful gas sensors (301, 302; hereinafter referred to as'sensors') are installed on the light guide plate, it is easy to mount and replace these sensors (301, 302), and various sensors In order to be able to vary and apply, a coupling groove 407 is formed around the upper surface of the light guide plate 403 as shown in FIG. The sensors 301 and 302 are also provided with the inclined protrusions 408 of the upper and lower light so that the coupling of the sensors 301 and 302 to the lighting lamp is simple and robust, and the inner side of the coupling groove 407 By installing a protruding contact 409 at the end, and installing a corresponding contact 410 at the corresponding part of the sensors 301 and 302 in contact with the protruding contact 409, it is possible to assemble one or more sensors without separate wiring work. It is possible to increase workability.

In addition, the electrical configuration shown in FIG. 8 in the present invention is a schematic illustration of only the microcontrol unit and the driver, but it is of course necessary to additionally install various known circuits such as input/output interfaces for the actual circuit design. Since it is not related to the technical features, detailed descriptions have been omitted for convenience.

In the above, the technical idea of the present invention has been described with the accompanying drawings, but this is an illustrative description of the best embodiment of the present invention, not limiting the present invention, and those of ordinary skill in the art It is obvious that anyone can modify and imitate dimensions, shapes, and structures within the scope of the technical idea of the present invention, and such modifications and imitations are included in the scope of the technical idea of the present invention.
