However, the air in a closed room may be contaminated due to increased carbon dioxide (CO ₂ ) content, or formaldehyde caused by building materials or household goods, due to the breathing of the occupants, thereby adversely affecting the health of indoor residents. Can. However, most people rarely recognize that the human effect of indoor pollution is more serious than outdoor air pollution, and they do not understand the nature and concentration of indoor pollutants.

The reason why indoor air pollution is more serious than air pollution is that natural dilution rate is large in case of air pollution, natural purification is possible with climate change, and it is suppressed through various regulations as social awareness of air pollution increases. This is because the indoor air is continuously circulated through artificial facilities in a limited space, or is exposed to various pollutants without protection for a long time in an enclosed area without such facilities. For this reason, when a person is active for a long time in a poorly ventilated room, it is impossible to maintain a comfortable state in the room due to an increase in CO ₂ and fine dust.

Referring to FIG. 1A, the electric stand 100a according to the first embodiment of the present invention includes a lamp 110a and a control panel 130a, and may optionally include a lampshade 120a.

The lamp 110a operates on the basis of electricity and control signals transmitted through the control panel 130a, and illuminates the surroundings or illuminates the light to create an atmosphere.

The lampshade (120a) is used for the purpose of protecting the eyes by increasing the degree of illumination by focusing the light from the lamp (110a) in one place, or to prevent the dazzle, it can be implemented in the form of covering the lamp (110a) .

At this time, the electric stand main body may include a stand 160a mounted on the lower surface so that the electric stand 100a does not collapse, and a vertical support 170a connected from the stand 160a to the lamp 110a.

1B is a perspective view schematically showing a mood lamp according to a first embodiment of the present invention. Referring to Figure 1b, the mood lamp 100b according to the first embodiment of the present invention includes a lamp (110b), a lampshade (120b), a control panel (130b) and a plug (140b) for coupling with an outlet installed on the inner wall do.

The lamp 110b operates on the basis of electricity and control signals transmitted through the control panel 130b, and illuminates the surroundings or illuminates the light to create an atmosphere.

Lamp shade (120b) is implemented in the form of overlaying the lamp (110b), so that it is possible to create an atmosphere using the light output from the lamp (110b).

The control panel 130b is a device for controlling the overall operation of the mood lamp 100b, and may be implemented to be located under the mood lamp 100b as in the example of FIG. 1B.

2 is a schematic block diagram of a control panel included in an electric stand or mood according to the first embodiment of the present invention. 1A, 1B, and 2, the control panels 130a, 130b included in the electric stand 100a or mood lamp 100b according to the first embodiment of the present invention include an indoor air pollution measurement unit 131 ), an operation information storage unit 132, a control unit 133, and a lamp driving unit 134.

The indoor air pollution level measuring unit 131 operates according to a control command from the control unit 133, and measures indoor air pollution level in the room where the electric stand 100a or mood lamp 100b is installed. At this time, the indoor air pollution measurement unit 131 may apply a variety of known indoor air pollution measurement sensors, and items (eg, fine dust (PM10), ultra fine dust (which is a maintenance standard for indoor air quality management)) PM2.5), ultrafine dust (PM1.0), carbon dioxide, formaldehyde, total bacterial bacteria, carbon monoxide, etc.) and recommended criteria for indoor air quality management (e.g., nitrogen dioxide, radon, TVOC, PM2.5, PM1.0, mold, etc.) can be measured.

The operation information storage unit 132 stores operation information of the electric stand 100a or mood lamp 100b set differently according to the indoor air pollution level. For example, the motion information storage unit 132 divides the fine dust concentration into a predetermined range according to the indoor fine dust concentration standard and illuminates the electric stand 100a or mood lamp 100b for each range of the fine dust concentration, or Color information, etc. can be set and saved differently. Examples of storage of the operation information storage unit 132 are illustrated in FIGS. 3A and 3B.

3A and 3B are diagrams for explaining an example of the information 30 stored in the motion information storage unit according to the first embodiment of the present invention, in accordance with the indoor fine dust concentration standards, the range of the fine dust concentration in four steps It is classified as and shows an example of setting and storing the illuminance or saturation value of an electric stand or mood for each step.

FIG. 3A is a view showing an example of storing differently set lux 33 according to the fine dust concentration (µg/m 3) 31. Referring to FIG. 3A, the fine dust concentration is 0-40 (µg). /㎥) roughness 300(lux), fine dust concentration 41~200(㎍/㎥), roughness 250(lux), fine dust concentration 201~1000(㎍/㎥) The illuminance is set to 200 (lux), and when the fine dust concentration is 1001 to 2000 (µg/㎥), the illuminance is set to 50 (lux). At this time, looking at the variation of the illuminance according to the increase in the concentration of fine dust, when the fine dust concentration is 0 ~ 1000 (㎍ / ㎥), when the range of the fine dust concentration set above due to the increase in the fine dust concentration changes It is found that although '50' is constantly decreased, when the fine dust concentration is 1001 (µg/㎥) or more, the change in illuminance is set to drop rapidly to '150'. This is to allow the user to quickly respond to the fine dust concentration when the predetermined reference value (for example, 1000 (µg/m 3 )) is rapidly reduced by reducing the illuminance of light.

Meanwhile, FIG. 3B is a diagram illustrating an example of storing color information (eg, HSV coordinates, etc.) 35 differently set according to the fine dust concentration (µg/m 3) 31. Referring to FIG. 3B, fine dust The HSV coordinates when the concentration is 0-40 (µg/㎥) are (0,0,100), the HSV coordinates when the fine dust concentration is 41-200 (µg/㎥) (0,20,100), and the fine dust concentration is The HSV coordinates at 201 to 1000 (µg/m 3) are set to (0,40,100), and the HSV coordinates when the fine dust concentration is 1001 to 2000 (µg/m 3) are set to (0,100,100). At this time, HSV coordinates (h,s,v) are one way of expressing color, and a method of arranging colors according to the method, h is Hue, s is Saturation, and v is Brightness Specify a specific color by using the (Value) coordinates. FIG. 4 is a view for explaining an example in which the saturation value is changed according to the first embodiment of the present invention, and the saturation value s is changed by '20' with respect to red, where the h value of the HSV coordinate is '0' And the color table when the brightness value (v) is fixed to '100'. Therefore, referring to FIGS. 3B and 4, when the fine dust concentration is 0 to 1000 (µg/m 3 ), the saturation of light is changed every time the range of the fine dust concentration is changed due to an increase in the fine dust concentration. As illustrated in,'A(0)'→'B(20)'→'C(40)' gradually changes, but when the fine dust concentration is 1001 (µg/㎥) or more, the saturation is'F(100) It can be seen that it changes rapidly. This is to allow the user to quickly respond to this by rapidly changing the saturation of light when the fine dust concentration exceeds a preset reference value (eg, 1000 (µg/m 3 )).

In the examples of FIGS. 3A and 3B, the range of the fine dust concentration is set in consideration of a case where the fine dust concentration is rapidly increased intermittently due to housework (eg, cooking, cleaning, etc.) in a general home. It is only an example for explaining. That is, the criteria for setting the range of the fine dust concentration are not limited to those illustrated in FIGS. 3A and 3B. In addition, in the example of FIGS. 3A and 3B, an example in which illuminance and color information is set in consideration of only a range of fine dust concentration is described, but the present invention is not limited to the above example. That is, various items (eg, fine dust (PM10), ultra fine dust (PM2.5), ultra fine dust (PM1.0), carbon dioxide, formaldehyde, total floating bacteria, carbon monoxide) are measured to determine indoor air pollution level. , Nitrogen dioxide, radon, TVOC, PM2.5, PM1.0, mold, etc.), and may further set illumination and color information by considering the range of the items together. For example, it may be possible to set the roughness and color information accordingly by considering the fine dust concentration and the carbon dioxide concentration together. Also, examples of illuminance or HSV coordinate values corresponding thereto are not limited to those illustrated in FIGS. 3A and 3B. That is, although FIG. 3B shows an example of changing the saturation value for red whose h value of the HSV coordinate is '0', the present invention does not limit the h value of the HSV coordinate to '0', and the change value is also chroma. It is not limited to the value s. For example, the present invention fixes the saturation value (s) and lightness value (v) of the HSV coordinates and changes the color value (h), or fixes the color value (h) and saturation value (s) of the HSV coordinates. And change the brightness value (v). Alternatively, the color information is not limited to HSV coordinate values, and other methods of expressing colors (eg, RGB coordinates) may be used. Also, the motion information storage unit 132 may store one or more of the illuminance information or color information as motion information.

Referring back to FIGS. 1A, 1B, and 2, the controller 133 generates a lamp control signal for controlling the operation of the lamp 110 based on the information stored in the operation information storage unit 132. To this end, the control unit 133 detects the operation information corresponding to the indoor air pollution level measured by the indoor air pollution measurement unit 131, but the operation information storage unit 132 operates as illustrated in FIGS. 3A or 3B. In the case of storing information, operation information corresponding to the fine dust concentration is detected, and a lamp control signal for controlling the operation of the lamp 110 is generated based on the operation information. For example, when the fine dust concentration transmitted from the indoor air pollution measurement unit 131 is '100', the control unit 133 detects the corresponding operation information from the operation information storage unit 132. That is, when the motion information storage unit 132 stores the motion information illustrated in FIG. 3A, the control unit 133 may obtain the illuminance 250 (that is, the motion information corresponding to the fine dust concentration '100' from the motion information storage unit 132) After detecting lux), a lamp control signal for adjusting the illuminance of the lamp 110 to 250 (lux) is generated. Alternatively, when the motion information storage unit 132 stores the motion information illustrated in FIG. 3B, the control unit 133 is an HSV coordinate value that is motion information corresponding to the fine dust concentration '100' from the motion information storage unit 132. After detecting (0,20,100), the lamp 110 generates a lamp control signal for outputting light of a color ('B' in FIG. 4) corresponding to the HSV coordinate value (0,20,100).

The lamp driving unit 134 drives the lamp 110 based on the lamp control signal. That is, the lamp driver 134 may adjust the illuminance of the lamp 110 when the lamp control signal includes illumination information, and may adjust the color of the lamp 110 when the lamp control signal includes color information. .

At this time, looking at the variation of the illuminance according to the increase in the concentration of fine dust, when the fine dust concentration is 0 ~ 1000 (㎍ / ㎥), it is rotated every time the range of the fine dust concentration set above due to the increase in the fine dust concentration It can be seen that although the angle is constantly changed by 15°, when the fine dust concentration is 1001 (µg/㎥) or more, the change width of the angle of view is set to change rapidly to 45°. This is, as the fine dust concentration increases, the overlapping portion of the light or shading part of the first and second lampshades 321 and 323 is gradually decreased, and the ambient light is decreased, and the fine dust concentration is a preset reference value ( For example, when it exceeds 1000 (µg/m 3 ), the overlapping portion of the mining part or the light blocking part of the first and second lamp shades 321 and 323 is minimized to rapidly decrease the illuminance of the surroundings, so that the user can This is to enable rapid response. In particular, when the first and second lamp shades 321 and 323 are equally divided into four regions as shown in the above example, and include two mining portions and two light blocking portions, respectively, the first and second lamp shades 321, 323), if the rotation of any one of the 90 °, the overlapping area of the mining and light-shielding portion is minimized, the illumination of the electric stand is very low.

In the example of FIG. 10, the range of the fine dust concentration is set in consideration of the case where the fine dust concentration is increased intermittently due to housework activities (for example, cooking, cleaning, etc.) in the general household as in the case of FIGS. 3A and 3B. As one, it is only an example for explaining the present invention. That is, the example of FIG. 10 describes an example in which the rotation angle of the lampshade is set in consideration of only the range of the fine dust concentration, but the present invention is not limited to the above example. That is, various items (eg, fine dust (PM10), ultra fine dust (PM2.5), ultra fine dust (PM1.0), carbon dioxide, formaldehyde, total floating bacteria, carbon monoxide) are measured to determine indoor air pollution level. , Nitrogen dioxide, radon, TVOC, PM2.5, PM1.0, mold, etc.), and may further set the rotation angle of the lampshade in consideration of the range of the items. For example, it is also possible to set the rotation angle of the lampshade accordingly by considering the fine dust concentration and the carbon dioxide concentration together.

Referring to FIGS. 7 to 9 again, the controller 333 generates a lampshade control signal for controlling the operation of the lampshade 320 based on the information stored in the motion information storage 332. To this end, the control unit 333 detects operation information corresponding to the indoor air pollution level measured by the indoor air pollution measurement unit 331, but the operation information storage unit 132 stores the operation information as illustrated in FIG. 10. If it does, the motion information corresponding to the fine dust concentration is detected, and a lampshade control signal for controlling the operation of the lampshade 320 is generated based on the motion information. For example, when the fine dust concentration transmitted from the indoor air pollution measurement unit 331 is '100', the control unit 333 detects the corresponding operation information from the operation information storage unit 332. That is, when the motion information storage unit 332 stores the motion information illustrated in FIG. 10, the control unit 333 rotates 30, which is the motion information corresponding to the fine dust concentration '100' from the motion information storage unit 332 After detecting °, a lampshade control signal for rotating any one of the first and second lampshades 321 and 323 by 30° is generated.

The lampshade driver 334 drives the first and second lampshades 321 and 323 based on the lampshade control signal. That is, the lampshade driving unit 334 rotates at least one of the first and second lampshades 321 and 323 based on the lampshade control signal, so that the first and second mining units 11 and 13 or the first and second 2 The overlapping portion of the light blocking portions 21 and 23 may be adjusted.

11 is a view for explaining the operating state of the lampshade of the electric stand according to the third embodiment of the present invention. That is, FIG. 11 rotates at least one of the first and second lamp shades 321 and 323 according to the concentration of fine dust, so that the first and second light-emitting parts 11 and 13 or the first and second light-blocking parts 21 , 23) is a view for explaining an example of adjusting the overlapping portion.

FIG. 11A illustrates a case in which the fine dust concentration is low, so that the overlapping portions of the first and second light-emitting portions 11 and 13 or the first and second light-blocking portions 21 and 23 are maximum. Referring to FIGS. 8 and 11, when the first light portion 11 of the first lamp shade 321 and the second light portion 13 of the second lamp shade 323 overlap, the lamp 310 Since the light output from is output through the overlapping portions of the first and second mining parts 11 and 13, the illuminance of the corresponding electric stand will be maximum.

11(b) illustrates an example in which at least one of the first and second lampshades 321 and 323 is rotated by 30° based on the lampshade illustrated in FIG. Doing. Referring to FIGS. 8 and 11, a portion in which the first light portion 11 of the first lamp shade 321 and the second light portion 13 of the second lamp shade 323 overlap is based on FIG. 11(a). It can be seen that it was reduced by about 2/3. In this case, the amount of light output from the lamp 310 will also be reduced by about a third compared to the case of FIG. 11A.

11(c), the fine dust concentration becomes equal to or greater than a preset reference value, and by rotating at least one of the first and second lampshades 321 and 323 by 90°, the first mining part of the first lampshade 321 ( 11) and the case where the second light shade part 13 of the second lampshade 323 overlaps is illustrated as the minimum. At this time, FIG. 11 shows an example in which the first and second lamp shades 321 and 323 are equally divided into four regions, and each includes two light-emitting portions and two light-blocking portions. And the second light shade 321, 323 by rotating at least one of 90°, the first light shade part 11 of the first lamp shade 321 and the second light shade part 323 of the second light shade part 13 overlap. Although this is the minimum, if the light and light blocking portions of the first and second lamp shades 321 and 323 are implemented differently, the first light portion 11 and the second lamp shade 323 of the first lamp shade 321 are removed. 2 The angle of rotation for the mining portion 13 to overlap is the minimum will be a value other than 90°.
