Description

TECHNICAL FIELD [0001] The present invention relates to a dimming level adjusting method,

The present invention relates to a dimming level adjusting method using energy consumption of illumination, and more particularly, to a dimming level adjusting method using illumination energy consumption amount of lighting to reduce user's convenience and energy consumption when illuminating each space of a home or a building And a method of adjusting the dimming level.

Generally, lighting is used mainly for illuminating darkness (eg general lighting), but as the use of lighting has diversified gradually, mood lighting, advertising lighting, stage lighting, exterior lighting, landscape lighting and healing lighting Used lighting), and interior lighting.

Also, as the use of illumination is diversified as described above, the kinds of bulbs (or lamps) used for illumination are also increasing. For example, incandescent lamps or fluorescent lamps have been widely used as indoor or outdoor lighting lamps in the beginning, but in recent years, a lighting device having a long lifetime, low power consumption, and high luminance characteristics has been developed.

In addition, as the energy consumption due to the increase in energy consumption devices used in homes and buildings is increasing, the energy cost to be borne by the user is increasing. Accordingly, a method for reducing energy consumption is required. In particular, since the energy consumption (or power consumption) of the lighting is relatively larger than that of other energy consumption devices, the energy consumption of the lighting There is a need for a method that can reduce the amount of radiation.

For example, there is a dimming control method as a method for reducing the energy consumption of illumination. However, the conventional dimming control method is a method in which the brightness of the illumination is manually adjusted each time the user wishes, (I.e., turning on and off smoothly by dimming).

As a result, it has been difficult to expect the user's convenience and energy consumption to be reduced. For example, since the sensor light is illuminated when the user enters the vicinity of the illumination, there is a problem that the convenience of the user is low, for example, the user is afraid to enter the hall in the night hall.

In addition, the existing lighting design has been designed only for mood lighting and landscape lighting, and it has not been possible to design a lighting production scenario considering the reduction of energy consumption in the interior of a house or a building.

BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Registered Patent No. 10-0760981 (registered on September 17, 2007, an LED lighting device in which various kinds of illumination are performed and a control method thereof).

In the present invention, the energy consumption by the illuminance unit with respect to the current average illuminance in the tenth step is calculated by (current energy consumption / current average illuminance).

In the present invention, the corrected average roughness of the twelfth step may be calculated by dividing the difference of the target energy consumption with respect to the current energy consumption by the energy consumption by the illuminance unit ((current energy consumption - target energy consumption) ).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a dimming level adjusting method using energy consumption of illumination according to the present invention will be described with reference to the accompanying drawings.

In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is a diagram illustrating a schematic configuration of an apparatus for calculating energy consumption and a dimming level according to an exemplary embodiment of the present invention. Referring to FIG.

1, the energy consumption calculation and dimming level control apparatus according to the present embodiment includes a main control unit 110, a dimming control unit 120, an energy consumption measurement unit 130, a storage unit 140, Unit 150, and a communication unit 160.

The sensor unit 150 includes an illuminance sensor that detects illuminance of a space for illumination control. The sensor unit 150 divides the space into a plurality of illumination regions, and detects illuminance for each region. Accordingly, the sensor unit 150 includes a plurality of illuminance sensors for detecting the illuminance of each space.

The dimming control unit 120 performs dimming control on each of the lights LAMP-1 and LAMP-n of the illumination unit 200. However, since the circuit for performing the dimming control can use any one of the well-known techniques, a detailed description of the dimming control unit 120 will be omitted in the present embodiment.

The dimming control unit 120 may be configured to control the dimming of the illumination unit 200 according to a control signal output from the main control unit 110 instead of the dimming switch And the like.

At this time, the illumination unit 200 may designate a plurality of lights (LAMP-1, LAMP-n) as a group for each area or individually designate them.

Therefore, the dimming control unit 120 can perform group control or individual control of dimming of each of the lights LAMP-1 and LAMP-n of the illumination unit 200.

When the dimming control unit 120 performs group control or individual dimming for each of the lights LAMP-1 and LAMP-n of the illumination unit 200, the energy consumption measuring unit 130 may perform group control Measure the energy consumption consumed by the individually controlled corresponding lights (LAMP-1, LAMP-n).

For example, when it is assumed that the dimming control unit 120 individually controls one of the lights LAMP-1 and LAMP-n, that is, the dimming control unit 120 dims the individual lights individually The energy consumption measuring unit 130 measures energy consumption (or power consumption) according to the dimming level of the dimming-controlled illumination.

The energy consumption (or power consumption) measured by the dimming control unit 120 in controlling the dimming level for each illumination is stored in the storage unit 140.

2, the storage unit 140 stores at least one characteristic information (e.g., a lighting type, a consumed electric power, and a power consumption) according to each illumination type (e.g., A illumination type, B illumination type, n illumination type, , The dimming control signal and system, energy consumption according to the dimming level, etc.) in a table form.

FIG. 2 is an exemplary view showing characteristic information stored in a table form according to the illumination type in FIG.

The storage unit 140 (or database) stores characteristic information about the illumination type corresponding to the number of illumination types for the lights installed in a space of a home or a building.

The characteristic information of each illumination type stored in the storage unit 140 is transmitted to the server unit 300 through the communication unit 160. [

Accordingly, the server unit 300 can share the property information of each illumination type with the energy consumption amount calculation and dimming level adjustment device installed in other homes or buildings.

As described above, the energy consumption calculation and the dimming level adjusting device installed in other homes or buildings through the server unit 300 share characteristic information for each lighting type, so that the energy consumption according to the dimming level of the lighting type in each home or building Even if you do not measure the energy consumption of each home or building, you can quickly and easily produce space-specific lighting considering the energy consumption.

The main control unit 110 automatically calculates (or measures) the property information (including the energy consumption amount) of each illumination type of illumination installed in a space of a home or a building and stores it in the storage unit 140 (see FIG. 4) .

Also, the main control unit 110 may share the property information of each illumination type of illumination installed in another home or building through the communication unit 160 and the server unit 300. [

Also, the main control unit 110 shares an illumination directing scenario of lights installed in other homes or buildings through the communication unit 160 and the server unit 300 (see FIG. 3).

FIG. 3 is an exemplary diagram showing the illumination directing scenario and the power consumption according to the table, in FIG.

However, since the energy consumption (or power consumption) may vary depending on the number and arrangement of the lights installed in the space, and the desired illumination (or the target average illumination), the illumination presentation scenario may be The number and arrangement of the lights installed in the space, and the desired illuminance (or the target average illuminance).

At this time, the illumination directing scenario can be adjusted (or designed) by each hour, day (date, season), weather, and space (i.e., .

By improving the user's convenience through the lighting directing scenario including the adjustment of the dimming level (for example, improving the disadvantages of existing sensor lighting by illuminating with minimal illumination even when the user is not approaching it) while reducing energy consumption It is possible to reduce the energy consumption by changing the dimming level according to the area even in the case of the lighting installed in the space). A specific method for this will be described with reference to the flowchart of FIG.

4 is a flowchart illustrating an energy consumption calculation method according to an embodiment of the present invention.

As shown in FIG. 4, the main control unit 110 checks whether characteristic information on illumination type of illumination installed in a space of a home or a building is stored in the storage unit (or database) 140 (S101).

For example, the storage unit (or the database) 140 previously stores (or measures) the property information on the illumination type of the illumination installed in the space of the home or the building and stores the property information in advance or download it from the server unit 300 in advance You can save it.

As a result of the check (S101), if the characteristic information about the illumination type of illumination installed in the space of the home or the building is not stored in the storage unit (or the database) 140 (NO in S101), the main control unit 110 The dimming level for the corresponding illumination is controlled from the minimum (or maximum) to the maximum (or minimum) in units of a predetermined unit (S102). When the dimming level for the relevant illumination is controlled in a predetermined unit, Or energy consumption) is measured and stored in the storage unit (or database) 140 (S103).

The step of measuring and storing the power consumption (or the energy consumption) of the unit control process of the dimming level (S102) is performed until the adjustment of the dimming level from the minimum (or maximum) to the maximum (S104).

When the adjustment of the dimming level and the power consumption (or energy consumption amount) from the minimum (or maximum) to the maximum (or minimum) is completed (YES in S104), the main control unit 110 determines the total energy consumption (Or power consumption) is calculated (S105).

Also, the total energy consumption amount (or power consumption) for each of the calculated illumination directing scenarios is also stored in the storage unit (or database) 140.

Accordingly, the main control unit 110 can fine-tune the lighting-directing scenario (for example, to maintain the target average illuminance of the space as much as possible) while reducing the user's convenience For example: Even the lighting installed in the same space can adjust the dimming level differently depending on the area) (see FIGS. 5 and 6).

FIG. 5 is an exemplary diagram for explaining a reason and a method for performing dimming control according to an area of an illumination installed in an indoor space according to an embodiment of the present invention.

For example, as shown in FIG. 5, when a large number of lights are installed in an indoor space of a home or a building, in order to reduce energy consumption, a switch And the light is connected to the wiring (that is, the switch and group lights are directly connected to the wire). However, in the area where the natural light is emitted through the window, it is too bright when the lighting is turned on, and may be slightly dark when the lighting is turned off. This situation differs from the side of the natural lighting window. Therefore, by controlling the dimming according to the area affected by the natural lighting, energy consumption can be reduced.

However, when the dimming control is manually performed by a person, the degree of adjustment is different according to the feeling of the person. Therefore, it is difficult to adjust the average illuminance of the space to the target average illuminance and also depending on the weather Active adjustment is difficult, so you may end up not adjusting the dimming level.

Therefore, it is necessary to automatically adjust the dimming level so as to reduce the total energy consumption (or power consumption) while preventing the user's convenience from deteriorating (for example, keeping the target average illuminance of the space as much as possible).

6 is a flowchart illustrating a method of adjusting a dimming level according to an exemplary embodiment of the present invention.

As shown in FIG. 6, the main control unit 110 sets the type and number of lights installed for each space area (S201).

At this time, the user can arbitrarily set the illumination area, or the main control unit 110 can automatically set the illumination area through illuminance measurement. Accordingly, when the main control unit 110 automatically sets an illumination area through illuminance measurement, it is possible to actively adjust the illumination area according to the weather (season) or the day of the week.

Accordingly, a plurality of illuminance sensors are disposed in the indoor space.

The main control unit 110 measures the current illuminance for each area in which the illumination is installed (S202).

The main control unit 110 calculates a target average illuminance according to a lighting directing scenario for each room (e.g., toilet, hall, office, lobby, hot tub, etc.) (S203).

At this time, the target average roughness may be directly designated by the user or may be recommended through testing. Also, the optimum target average illuminance can be calculated by referring to the illumination presentation scenario table for each hour, day of the week, and weather.

The main control unit 110 calculates the roughness difference for each area provided with the target average roughness illumination (S204).

The main control unit 110 adjusts the dimming level of illumination for each area in correspondence with the illuminance difference of each area in which the calculated illumination is installed (S205).

For example, referring to FIG. 5, the region 1 is most affected by natural lighting, so the dimming level is reduced to 80%, the region 2 is less influenced by natural lighting, so the dimming level is reduced to 50% Reduces the dimming level to 30% as it is least affected by natural lighting. However, the dimming level may vary according to time, day of the week, and weather.

When the dimming level adjustment for each area is completed as described above, the main controller 110 measures current illuminance for each illuminated area (S206).

The main controller 110 can continuously track changes in illumination in real time by periodically continuously measuring the current illuminance per area in which the illumination is installed.

Also, the main control unit 110 calculates the current average illuminance using the current illuminance for each area in which the illumination is installed (S207).

The main controller 110 compares the current average illuminance with the target average illuminance to check whether the current average illuminance is the same within the error range (S208).

If it is determined in step S208 that the current average illuminance and the target average illuminance are different from each other (NO in S208), the main control unit 110 repeatedly performs steps S204 to S208 to repeatedly .

If the current average illuminance is equal to the target average illuminance as a result of the check S208 (YES in S208), the main control unit 110 determines whether the current energy consumption (or the current average illumination intensity) corresponding to the current average illuminance (S209), and calculates an energy consumption amount by illuminance unit (i.e., current energy consumption amount and current average illuminance) with respect to the current average illuminance (S210).

Then, the main control unit 110 calculates the target energy consumption difference with respect to the current energy consumption (S211).

Also, the main control unit 110 calculates a corrected average roughness corresponding to the difference of the target energy consumption with respect to the current energy consumption (S212).

That is, since the energy consumption amount per illuminance unit for the current average illuminance (= the target average illuminance) is calculated in step S210, the difference in the energy consumption amount is divided by the energy consumption amount by the illuminance unit Energy consumption) / energy consumption per illuminance unit) The corrected average illuminance can be calculated.

Accordingly, the main control unit 110 calculates the target average roughness reflecting the corrected average roughness to the current average roughness (== target average roughness) (S213).

Here, "==" is a sign indicating that the current average illuminance is equal to the target average illuminance.

If the target average roughness is changed to reflect the corrected average roughness as described above, the main control unit 110 returns to step S204 and repeats the process of adjusting the roughness of the area in which the illumination is installed.

However, if the illuminance level is adjusted according to the illuminated area by following the target average illuminance as described above (i.e., the dimming level is adjusted for each illuminated area), if the dimming level is rapidly adjusted, So that it is preferable to adjust the dimming level gradually based on a predetermined time in units of the dimming level so as not to feel an uncomfortable feeling.

As described above, according to the embodiment, energy consumption can be taken into consideration when designing lighting for each space of a home or a building, thereby reducing the energy consumption of the lighting in a home or a building, and improving the user's convenience. So that it can be designed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, I will understand the point. Accordingly, the technical scope of the present invention should be defined by the following claims.
