Description

[0001] LIGHT-SHELF APPLYING OPERATION TYPE MODULE [0002]

[0001] The present invention relates to a movable shelf for a movable module, and more particularly, to a movable shelf for a movable module which is disposed adjacent to a window to introduce mainstream light into the room.

Generally, the amount of energy used in a building is 38% of the total energy consumption, of which 22% is consumed as lighting energy. Therefore, researches on the improvement of the performance of window and sunshade system for reducing energy of illumination are continuing.

Among them, the light shelf reflects outdoor natural light and can enter the interior of the room, thereby reducing illumination energy and preventing natural light from being directly introduced into the room, thereby improving indoor comfort. Therefore, research is continuing due to the efficiency of the light shelf.

The prior art for such a light shelf has already been disclosed in Korean Registered Patent No. 1306640 (optical shelf unit capable of adjusting the angle and structure of a building envelope using the same). The present invention is characterized in that it comprises a main body having an opening formed therein, and a light shelf disposed in the opening and capable of controlling or blocking light.

However, in the case of the conventional light ray module including the above-described registered invention, only the variables such as the width, angle, installation position and height of the light ray module without considering the position of the occupant are taken into consideration, and the efficiency of the light ray module is not improved. Therefore, the conventional light shelf has a problem in that the variation of the light inflow direction is limited due to the inflow angle of the light entering the room through the window and the position of the occupant.

1 and 2, the optical shelf system 100 according to the present embodiment includes a light shelf 110, a driving unit 130, a sensor unit 150, and a control unit 170.

First, the light shelf 110 is disposed adjacent to one side of the window 10 in the room, so that the inflow path of the light transmitted through the window 10 can be varied. The light shelf 110 may include a reflective portion 111 and a variable portion 113.

First, the reflecting portion 111 reflects the light transmitted through the window 10 to the room. To this end, the reflection unit 111 may be provided with a plurality of reflection plates 111a. Here, the plurality of reflection plates 111a are each provided as a plate having a predetermined width. Each of the reflection plates 111a may be provided so as to have reflectance at least on one side thereof for reflecting the light introduced into the room through the window 10. [ The plurality of reflectors 111 may be arranged to be converged by the varying unit 113 so that there is no mutual interference at the time of tilting by the variable unit 113 described later.

The variable portion 113 controls the angle of the reflecting portion 111 with respect to the window 10 so that the angle of reflection of the light transmitted through the window 10 can be varied. To this end, the variable portion 113 may include first and second frames 113a and 113b.

First, the first frame 113a is disposed so as to be tiltable with respect to one surface of the window 10. For example, the first frame 113a may be provided as a substantially rectangular frame having an opening formed therein and may be arranged to cross the window 10 on one side thereof. However, the form of the first frame 113a described in the present embodiment is an embodiment for explaining the present invention, and the form of the first frame 113a is not limited.

Further, the first frame 113a can be disposed adjacent to the window 10 by the rotation shaft 113aa. Here, the rotating shaft 113aa can cause the first frame 113a to be tilted with respect to the window 10 in the z-axis direction shown in Fig. The rotation shaft 113aa may be provided to be supported by the window 10 between the window 10 and the first frame 113a, but this is an embodiment for explaining the present embodiment, and the rotation shaft 113aa may be separately provided And may be disposed on a predetermined height from the ground.

Meanwhile, as described above, the plurality of reflection plates 111a are disposed inside the opening of the first frame 113a and are supported by the first frame 113a. Here, the plurality of reflection plates 111a may be arranged to cross the first frame 113a. The first frame 113a may be provided with a plurality of second frames 113b such that the first frame 113a and the plurality of reflection plates 111a are connected to each other.

Here, the plurality of second frames 113b are disposed so as to pass through the openings of the first frame 113a, respectively, so that the plurality of reflectors 111a are supported by the first frame 113a. At this time, the plurality of second frames 113b may pass through the substantially central portion of the reflection plate 111a, and the reflection plate 111a may be tilted together or separately in the x-axis direction shown in FIG.

Meanwhile, the driving unit 130 is interlocked with the optical shelf 110 to drive the optical shelf 110. Here, the driving unit 130 is connected to the variable unit 113 so that the first and second frames 113a and 113b can be tilted by external power or attraction force.

Here, when the driving unit 130 drives the light shelf 110 based on the electric power, the driving unit 130 drives the first and second frames 113a and 113b When the driving unit 130 drives the light shelf 110 based on the attraction force, the first and second frames 113a and 113b are driven by a combination of the driving gear and the idle gear controlled by the attraction force, Can be tilted.

Since the driving unit 130 can be understood by a known technique, a detailed description thereof will be omitted.

The sensor unit 150 measures at least one of the amount of light incident on the reflection unit 111 and the position of the occupant located in the room. For this, the sensor unit 150 may include an illuminance sensor or a human body sensor (PIR sensor).

For example, the light intensity sensor may be disposed adjacent to the window 10 or the light shelf 110. [ The illuminance sensor senses the amount of light provided to the light shelf 110 through the window 10 or senses the illuminance of the room and provides the measured information to the control unit 170. The human body detection sensor is disposed in the room, and can sense the position of the occupant and provide the measured information to the controller 170. [ Here, as the human body detection sensor system, a macro position recognition system, a micro position recognition system, and an ad hook position recognition system can be used.

Meanwhile, the controller 170 may be interlocked with the sensor unit 150 and the driving unit 130, respectively. At this time, the control unit 170 can be interlocked with the sensor unit 150 and the driving unit 130 by a wired or wireless system, and based on the information provided from the sensor unit 150, 110).

For example, the control unit 170 tilts the first and second frames 113a and 113b based on the amount of light to the reflection unit 111 or the light amount information of the room provided from the sensor unit 150, So that the light is guided to the area where the light is not directly irradiated or the light is guided to the area where the user is located.

The control unit 170 may be a home network system or a separate system. Since the control unit can be understood as a known technology, a detailed description thereof will be omitted.

Hereinafter, the implementation of the light beam according to the present embodiment will be described in detail with reference to the accompanying drawings.

FIG. 3 is a diagram illustrating the implementation of a light module for a movable module according to this embodiment.

As shown in FIG. 3, the light shelf 110 according to the present embodiment determines the directionality of the light entering the room by the external environment such as the sun altitude and the azimuth angle, regardless of the position of the occupant of the existing light shelf Thereby reducing the problem of low energy reduction efficiency.

That is, in the optical shelf 110 according to the present embodiment, not only the first frame 113a is tilted with respect to the window 10, but also the plurality of reflection plates 111a are tilted together or individually, 10 so that the light can be provided not only in a horizontal direction but also in an area in which sunlight does not directly flow.

When a plurality of occupants P1 and P2 are located in the room 30, the plurality of reflection plates 111a can be tilted together or separately based on the information provided from the sensor unit 150, and the angle can be controlled . Thus, the light shelf 100 can guide light to respective areas where a plurality of occupants P1 and P2 are located.

Hereinafter, a movable shelf for a movable module according to the present embodiment will be described in more detail with reference to a test example.

The standard for lighting control was based on the KS illuminance standard, 400 lux, which is the working standard illuminance in living room and living room.

[Table 1]

2) Calculation method of lighting energy usage

In this test, the performance of the present optical lathe system, fixed optical lathe system, and movable optical lathe system was established and the lighting power consumption was calculated according to the lighting control after the proper operation.

As shown in Fig. 4, the performance verification was carried out in the same manner as the performance verification of the optical shelf system of the present invention, and the performance evaluation was performed from 10:00 am to 3:00 pm. The external illuminance was set based on the related study for each time of day, and the maximum illuminance was set to 80,000 lux for the lower limb, 60,000 lux for the spring and autumn, and 30,000 lux for the comrades. In order to calculate the energy consumption of illumination energy, the energy consumption of illumination energy was calculated based on 15 days including 24 periods (15 days per season) including spring, spring, and winter solstice, and artificial sunlight was used.

2. Performance Evaluation Configuration

1) Overview of energy performance evaluation

In this test, a test bed was constructed to verify the efficiency of the optical shelf system. As shown in Table 2, the test bed is designed with a width of 4.9 m, a length of 6.6 m, and a ceiling height of 2.5 m. The opening size is 2.2 m wide and 1.8 m high.

[Table 2]

An artificial sunlight was built outside the test bed, and the brightness of each lamp was adjusted by adjusting the brightness of each lamp. The height and angle of the artificial sunlight were adjusted to create the seasonal and external environment according to the solar altitude. As shown in FIG. 5, the illuminance sensor for measuring the illuminance of the experimental space was arranged at intervals of 2.200 mm and was installed at a distance of 45 cm from the floor based on the height of the work surface.

2) Zone setting and optical shelf module setting for position recognition

As shown in FIG. 6, the performance evaluation of the optical shelf system of the present test was performed so that the test bed was divided into four areas and the optical shelf was divided into four.

3) Optical shelf system configuration

In order to verify the performance of this optical shelf system, this test was set up as a test variable for the tilting angle of the optical beam among various variables of the optical shelf system, and the results were derived. In this case, the light shelf size (width) is 300 mm outside, the height of the light ray is 1800 mm, the reflectance of the reflector is 85%, the altitude of the middle is 76.5,

In this test, the change of the tilting angle of the reflector was experimented by raising the range of -10 ~ 30 ° in 5 ° increments. In the first frame, the range of -30 ~ 30 ° was set to operate in 3 ° increments. Respectively.

3. Results of the lighting energy performance evaluation of the light shelf system

In order to evaluate the energy reduction performance of the optical shelf system, the above-described fixed optical shelf system and the movable optical shelf system were linked with the illumination to calculate the illumination energy consumption, and the test bed was divided into four And an illuminance sensor was disposed. The sensor and the lighting are interlocked so that the lighting control is based on the standard illuminance of 400 lux, which is the standard of the living room working standard of the KS illuminance standard.

1) Lighting energy consumption of fixed type light shelf system

Fixed type light shelves calculate lighting energy consumption power by turning on / off the power according to the illuminance of 0 ° of light shelf angle and 400 lux of occupant standard illuminance. As shown in Table 4, the total energy consumption of lighting energy consumption was 1.524kWH for winter, 15.240kWH for spring and 7.620kWH for spring, and total 24.384kWH for 60 days including spring, spring, and winter.

2) Lighting energy consumption of movable optical shelf system

The movable light shelf system is a light shelf in the angle control stage. The angle of the light shelf with the number satisfying the standard illuminance 400lux among the four indoor illuminance specific values is selected as a priority, and the number of the sensors satisfying 400lux is 400lux The angle of proximity was reflected. The optimum angle of the light shelf for the winter solstice, spring, and fall was 10 ° to the outer illuminance of 20,000 lux, -10 ° to the outer illuminance of 30,000 lux, 30 ° to the outer illuminance of 50,000 lux, The illuminance was set at 30 ° for 60,000 lux, 20 ° for external illumination of 70,000 lux, and 20 ° for external illumination of 80,000 lux.

Therefore, the lighting energy consumption power according to the proper angle of the movable light shelf system was 0, 0, and 7.620 kWH, respectively, and the total energy consumption was 15.240 kWH. Especially for comrades, 400lux was satisfied because of low altitude.

3) Lighting energy consumption power of this light shelf system

In this light shelf system, the angle of the light ray half against the window is tilted according to the position of the occupant based on the proper angle of the movable ray group. The light shelf was tilted according to the position and season of the occupant. In the case of spring and fall, the light intensity of Zone 1 is insufficient for the appropriate angle of 30 ° of reflector, so a light shelf is necessary when Zone 1 is occupied. If there is occupant in another Zone, It is necessary to consider the change of indoor illumination. In the case of the lower limb, tilting of the light beam is required for the case where the occupant is located in the Zone 1 and Zone 3 with respect to the appropriate angle of 20 °, and the light shelf control sequence according to the position of the occupant is not the position of the sensor So the occupants differ in Zone 1 and Zone 3dp positions. However, in the case of the comrades, the standard illuminance of Zone 1 to Zone 4 is satisfied through the angle control of the light shelf, and the tilting of the light beam is not required.

The lighting energy consumption according to the angle of the beam and the angle control of the light beam satisfies the standard illuminance of 400lux through the angle control of the light beam irrespective of the winter, spring, and fall, and the illumination energy consumption is 0kWH. However, in this test, the power consumption for the operation of the light shelf was calculated and reflected. The power consumption for the operation of the light shelf is based on a 10W motor, and the power consumption for the light shelf angle control is calculated assuming a 1 minute operation per hour. The light shelf driving time for the position recognition is set to 1 minute . Also, based on the research on location recognition, it was applied to change the zone for 10 times of location recognition per hour, and it was calculated as power required for controlling the light shelf.

In case of using this light shelf reflecting the power for operation of the light shelf, 24.384 kWH and 15.240 kWH of fixed light shelf and movable light shelf were used, whereas 0 kWH was used, and the illumination energy reduction efficiency was analyzed to be high. In addition, the motor power consumption for the first frame angle control and the reflector angle control is 0.038 kWH and 0.375 kWH, respectively, so that the energy consumption can be reduced by 98.3% and 97.3% when the motor usage for operation is reflected.

As such, the light shelf has an effect of improving the mining performance by easily changing the light inflow direction according to the inflow angle of the light and the position of the occupant.

In addition, the light shelf has the effect of improving the mining ratio of the entire room or a specific area by changing the inflow direction of the light together or individually by a plurality of reflectors.

Further, the light shelf has an advantage that energy can be reduced as compared with a conventional light ray.

The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms.
