Accordingly, in order for the light emitting devices of different colors to display the same illuminance, the light emitting devices of each color must be driven at different duty ratios. It serves to control each of these duty ratios so that they can be shown.

The number of the lighting unit 104 may vary depending on the size of the space in which the lighting unit 104 is to be installed.

It is determined whether all the light sources LS provided in the lighting unit 104 are turned off and on. For example, when a person who is within the sensing range of the acoustic sensor sensor SS claps three times, the acoustic sensor SS supplies the detection result to the first light source control unit LC1 in response to the clapping sound. . Then, the first light source controller LC1 turns off or turns on all the light sources LS provided in the lighting unit 104.

That is, the second light source controller LC2 may effectively produce an emotional atmosphere that is more faithful to the human emotional feeling by adjusting the illuminance of the light source based on the fuzzy inference algorithm.

For example, in the case of a school classroom, the lighting unit 104 installed in the classroom emits blue light having an illuminance of 7600 to 8000 Kelvin in the classroom, and 4200 to 4600 Kelvin in the language domain. Students can improve their academic achievement by emitting white light with illuminance and emitting red light with illuminance of 2200 ~ 2600 Calvin in art and music related art class.

On the other hand, in the case of the auditorium, it is possible to focus the attention of the speaker or the audience by focusing the lighting on the speaker, and enhance the directing effect by illuminating the light to the audience side during the performance or the play.

In addition, in the case of a restaurant, the lighting unit 104 may be controlled to produce a bright and lively atmosphere.

On the other hand, the lighting management apparatus according to the present invention may further include a foreign material removal unit (PR).

4 is a view showing the foreign matter removing unit according to the present invention, Figure 5 is a cross-sectional view taken along line I ~ I of FIG.

First, the lighting unit 104 in the present invention further includes a reflector plate RT, as shown in FIG. 4. This reflecting plate RT is located above the light sources LS, as shown in FIG. The reflecting plate RT serves to increase the light utilization efficiency by reflecting the light emitted upward from among the light emitted from the light sources LS. As shown in FIG. 5, the reflecting plate RT has a shape in which the English W is turned upside down, and the shape of the reflecting plate RT is not limited to this shape. That is, the form of this reflecting plate RT may be any form as long as it is a structure capable of reflecting light from the light source downward.

The foreign substance removing unit PR according to the present invention serves to remove the foreign substances formed on the reflector plate RT. That is, foreign matters such as dust may be adsorbed to the reflector plate RT. When the foreign matter is adsorbed on the inner surface of the reflector plate RT, the reflection efficiency of the reflector plate RT decreases, thereby reducing light utilization efficiency.

The foreign matter removing unit PR in the present invention prevents the reflection efficiency of the reflecting plate from being reduced by removing the foreign matter adsorbed on the reflecting plate RT.

To this end, the foreign material removing unit PR, as shown in Figure 5, includes a foreign material amount measuring unit (PM) and the vibration applying unit (VG).

The foreign matter quantity measuring unit PM measures the amount of the foreign matter formed on the surface of the reflecting plate RT, that is, the inner surface of the reflecting plate RT, and the foreign matter around the reflecting plate. This foreign matter quantity measuring unit PM is provided on the inner surface of the reflecting plate RT. In this case, in order to prevent a decrease in light utilization efficiency, the external appearance of the foreign matter quantity measuring unit PM may be coated with a material having excellent light reflection efficiency, for example, a material such as a metal. The dust measuring unit may be used as the foreign matter quantity measuring unit PM.

The vibration applying unit VG determines whether or not the reflection plate RT is vibrated based on the measurement result from the foreign matter quantity measuring unit PM. The vibration applying unit VG may be built in the power control driver PCD.

When the measured value measured by the foreign substance quantity measuring unit PM exceeds a preset reference value, the foreign substance quantity measuring unit PM outputs the vibration applying control signal to the vibration applying unit VG. Then, the vibration applying unit VG vibrates the reflecting plate RT in response to the vibration applying control signal. As the reflecting plate RT vibrates, foreign substances adsorbed on the reflecting plate RT are separated from the reflecting plate.

In addition, the foreign matter quantity measuring unit PM may set the magnitude of the vibration applying control signal by subdividing the intensity of the exceeded measured value step by step when the measured measured value exceeds a preset reference value. For example, when the intensity of the exceeded measured value is located in the range of 1 to 5, the foreign matter measuring unit PM outputs a vibration applying control signal having a magnitude of level 1, and the intensity of the exceeded measured value is 6 to 5. When it is located in the range of 10, the foreign matter measuring unit PM may output a vibration applying control signal having a magnitude of level 2. Here, the vibration applying control signal of level 2 has a larger value than the vibration applying control signal of level 1. In this case, the vibration applying unit VG vibrates the reflector RT at a higher frequency when the vibration applying control signal of level 2 is applied than when the vibration applying control signal of level 1 is applied.

At this time, the vibration applying unit (VG) may vary the application time of the vibration instead of the strength of the vibration in accordance with the level. For example, the vibration applying unit VG vibrates the reflector RT for a longer time when the vibration applying control signal of level 2 is applied than when the vibration applying control signal of level 1 is applied.

On the other hand, the vibration applying unit (VG) may be composed of a plurality of diaphragms. That is, FIG. 6 is a view of the reflector of FIG. 5 in the direction of an arrow. As illustrated in FIG. 5, a plurality of diaphragms VP may be attached to an outer surface of the reflector RT.

7 is a view showing a foreign matter suction unit, the foreign material removal unit PR according to the present invention may further include a foreign matter suction unit PS as shown in FIG. 7.

The foreign matter suction unit PS sucks foreign substances separated from the reflector plate RT to prevent foreign substances detached from the reflector plate RT from falling onto objects or people located under the lighting unit, and also removes the foreign substances removed. can do.

To this end, a plurality of suction holes SH penetrating the reflecting plate RT is formed in the reflecting plate RT, and the suction port SE of the foreign matter suction unit PS is sucked through the plurality of suction pipes PT. It is connected to the holes SH.

As described above, the foreign material removing unit PR vibrates the reflector plate RT and simultaneously sucks the air around the light source LS to absorb the foreign matter adsorbed on the light source LS as well as the reflector plate RT and the foreign matter around the light source LS. Can be effectively removed.

Meanwhile, the foreign material removing unit PR may automatically determine whether or not the reflecting plate RT is vibrated based on the amount of the foreign matter as described above, but periodically reflects the reflective plate RT at a predetermined time regardless of the amount of the foreign matter. It can also vibrate. In this case, there is no need for a separate foreign material quantity measurement unit (PR) to reduce the cost.

On the other hand, the foreign material removing unit PR, when the amount of the foreign matter exceeds a predetermined value and all of the light sources LS installed in one lighting unit 104 satisfies the condition that all the lights out state to the lighting unit 104. The located reflector RT may be operated to vibrate for a predetermined time. The foreign material removing unit PR receives a numerical value of the foreign material amount through the foreign substance quantity measuring unit PM, and receives information on whether all the light sources LS are turned off through the lighting control unit 101. To this end, the vibration applying unit VG provided in the foreign material removing unit PR determines whether the reflecting plate RT is vibrated based on the amount of foreign matter and whether all the light sources provided in the one lighting unit 104 are turned off. . At this time, the vibration applied to the reflector plate RT may vary in intensity or time according to the amount of foreign matter as described above.

Meanwhile, the user accesses the Internet through the mobile communication terminal 105 and checks the information on the lighting unit 104, and the first light source control unit LC1 provided in the lighting control unit 101 through the mobile communication terminal. The operation of the second light source controller LC2 and the foreign substance removing unit PR is controlled. That is, the user can access the Internet through the mobile communication terminal 105 from the outside to check the illuminance of the light sources provided in the lighting unit 104, and if necessary, the first and second light source controllers LC1 and LC2 By controlling the operation remotely, the illuminance of the light sources may be adjusted, and by controlling the operation of the foreign material removing unit PR remotely, the reflection plate may be forcibly controlled.

The mobile communication terminal 105 may be a smart phone capable of a wireless local area network (LAN) such as wifi. The mobile communication terminal 105 may be equipped with a jog shuttle (jog shuttle) for adjusting the illuminance in the form of an application.
