Specifically, the supply current information of the first type light emitting diode and the second type light emitting diode necessary for the illuminance and color temperature of the light supplied from the light source unit can be obtained.

Fig. 4 is a diagram showing a concrete example of step S140 in Fig.

Referring to FIG. 4, the current information acquisition step S140 includes an illumination-based information acquisition step S142 and a color temperature-based information acquisition step S144.

5 and 6 are illustrative drawings for explaining FIG.

First, the illuminance-based information acquisition step will be described with reference to FIG. 5, and the color temperature-based information acquisition step will be described with reference to FIG.

Referring to FIG. 5, the abscissa is the current of the first type light emitting diode and the ordinate is the current of the second type light emitting diode.

Each of the plurality of straight lines shown in Fig. 5 can be defined as a straight line. Details will be described later.

The points Ic1, Ic2, ..., Icn-1, Icn on the abscissa are the current values of the first type light emitting diodes sequentially increasing.

Specifically, without supplying a current to the second type light emitting diode of the light source unit, only Ic1, Ic2, ... are sequentially supplied to the first type light emitting diode. , Icn-1, and Icn, respectively.

When a plurality of first type light emitting diodes are included in the light source unit, the current Ic1 is simultaneously supplied to the plurality of first type light emitting diodes, and the current Ic2 is simultaneously supplied to the plurality of first type light emitting diodes .

Ic1, Ic2, ... of the first type light emitting diode without supplying current to the second type light emitting diode. , Icn-1, and Icn can be obtained at each point of time when the current is supplied. Specifically, the illuminance values at this time are represented by L1, L2, ..., Icn. , Ln-1, and Ln.

That is, when the current of Ic1 is supplied to the first type light emitting diode, the illuminance of the light source portion is L1, the illuminance of the light source portion is L2 when the current of Ic2 is supplied to the first type light emitting diode, The illuminance of the light source unit when supplying the current is Ln-1, and the illuminance of the light source unit when the current of Icn is supplied to the first type light emitting diode may be Ln.

In the first type light emitting diode, Ic1, Ic2, ... , Icn-1, and Icn can be calculated through calculation. For example, the illuminance of the light source can be calculated through output information according to the input current of each light emitting diode. As another example, it is also possible to provide the first type light emitting diode Ic1, Ic2, ..., , Icn-1, and Icn can be used to measure the illuminance at each stage.

The points (Iw1, Iw2, ..., Iwn-1, Iwn) on the vertical axis are current values of a plurality of second type light emitting diodes sequentially increasing.

Specifically, the current is not sequentially supplied to the first type light emitting diode of the light source unit, but the current is sequentially supplied only to the second type light emitting diode, and the illuminance of the light source unit at this time is obtained. , Ln-1 and Ln, the values of the currents supplied to the second type light emitting diodes at the respective illuminance values are Iw1, Ic2, ... , Iwn-1, and Iwn.

When a plurality of second type light emitting diodes are included in the light source unit, it means that a current of Iw1 is simultaneously supplied to a plurality of second type light emitting diodes, and then a current of Iw2 is simultaneously supplied to a plurality of second type light emitting diodes .

When the current of Iw1 is supplied to the second type light emitting diode, the illuminance of the light source portion is L1, the illuminance of the light source portion is L2 when the current of Iw2 is supplied to the second type light emitting diode, and the current of Iwn- The illuminance of the light source part when supplied is Ln-1, and the illuminance of the light source part when the current of Iwn is supplied to the second type light emitting diode may be Ln.

In the second type light emitting diode, Iw1, Iw2, ... , Iwn-1, and Iwn can be calculated through calculation. For example, the illuminance of the light source can be calculated through output information according to the input current of each light emitting diode. As another example, it is also possible to provide the first type light emitting diode with the current Iw1, Iw2, ..., , Iwn-1, and Iwn can be used to measure the illuminance at each stage.

Then, the current value Ic1 of the first type light emitting diode corresponding to the illuminance value of L1 and the current value Iw1 of the second type light emitting diode can be linearly connected. The straight line connected at this time may be said to be a combination of a combination of the current of the first type light emitting diode and the current value of the second type light emitting diode necessary for providing the light of the illuminance value of L1 in the light source part. That is, if x is supplied to the first type light emitting diode current and y is simultaneously supplied to the second type light emitting diode after selecting any point (x, y) on the straight line, the illuminance value provided by the light source portion is predicted to be L1 do.

In the same way, the current value Ic2 of the first type light emitting diode corresponding to the illuminance value of L2 and the current value Iw2 of the second type light emitting diode can be connected by a straight line, and the first type light emission corresponding to the illuminance value of Ln- The current value Icn-1 of the diode and the current value Iwn-1 of the second-type light-emitting diode can be connected in a straight line, and the current value Icn of the first-type light-emitting diode corresponding to the illuminance value of Ln and the current The value Iwn can be connected in a straight line.

The plurality of straight lines are defined as the isoelectric lines having the illuminance values L1, L2, Ln-1, and Ln, respectively.

Each of the plurality of straight lines can be directly created, and the creation of L2, Ln-1, and Ln can be facilitated to have the same slope as the slope of the straight line having the illuminance value L1.

With the above-mentioned tandem wire, it is possible to select the supply current of the first type light emitting diode of the light source unit and the supply current of the second type light emitting diode necessary for providing light corresponding to the desired illuminance.

For example, in the case of a straight line corresponding to the illuminance value of L1, since the equation of the straight line is Y = (- Iw1 / Ic1) X + Iw1, if an arbitrary X value, that is, a current value of the first- The current value of the second type light emitting diode which is the corresponding Y value can be obtained. Using these values, the light source unit can obtain various combinations of the first type light emitting diode current value and the second type light emitting diode current value Can be obtained.

That is, the illuminance value can be regarded as a function of the current value of the first type light emitting diode and the current value of the second type light emitting diode, for example, Ln = f (Iwn) + g (Icn). Here, f, g may be a function related to illuminance characteristics of the first type light emitting diode and the second type light emitting diode and the number of the first type light emitting diode and the second type light emitting diode included in the light source portion, and may be a positive number, for example.

Then, a step of obtaining a current value corresponding to a desired color temperature can be proceeded.

Referring to Fig. 6, one straight line is shown in the graph of Fig. That is, only the straight line corresponding to the desired roughness was displayed. Specifically, the straight line in Fig. 6 is the isoelectric line having the illuminance value of Ln.

The current corresponding to the coordinates of an arbitrary point on the straight line in Fig. 6, that is, the horizontal axis value of an arbitrary point, is supplied to the first type light emitting diode, and a current corresponding to the vertical axis value of an arbitrary point is supplied to the second type light emitting diode The light source unit can provide light having an illuminance value of Ln.

If a point having a desired color temperature is selected from among arbitrary points on the straight line, a current to be supplied to the first type light emitting diode and a current to be supplied to the second type light emitting diode, which are necessary for providing light of desired illuminance and color temperature, .

The color temperature can be calculated as a linear sum of the color temperatures of the first type light emitting diode and the second type light emitting diode.

Specifically, the color temperature of the first type light emitting diode is defined as CCT, and the color temperature of the second type light emitting diode is defined as CWT. For example, the CCT may be 6000k, and the CWT may be 3000k, which may be predetermined values that are inherent values of each light emitting diode.

Assuming that the total length of the line segment is D and the distance from the point to the longitudinal axis segment is a, the distance from the arbitrary point to the lateral axis segment can be D-a based on the point shown on the straight line in Fig. The coordinates of the point in Fig. 6 are defined as (P, Q).

The color temperature corresponding to the point in FIG. 6 can be expressed as (aCWT + (D-a) CCT) / (a + (D-a)). That is, when the color temperature at the point is defined as CTa, CTa = (aCWT + (D-a) CCT) / D.

The color temperature can be easily obtained through this formula. That is, CWT and CCT are already known information as described above, and D is the total length of the straight line.

Therefore, when the desired color temperature value is CTa, the value of a or D-a can be obtained.

In summary, the straight line corresponding to the desired illuminance value is selected in the graph of Fig. 5, and a is obtained as a point corresponding to the desired color temperature among the selected straight lines. Since Icn and Iwn are obtained as described above, if a is obtained, the values of the coordinates of the point in FIG. 6, for example, the coordinates (P, Q) Value can be obtained. For example, since a / P = D / Icn, P = a * Icn / D, the Q value can be obtained by using this value. That is, Q can be used by using a straight line equation Q = (- Iwn / Icn) P + Iwn.

P, which is the current to be supplied to the first type light emitting diode of the light source unit, and Q, which is the current to be supplied to the second light emitting diode, can be finally obtained.

That is, P, which is a current to be supplied to the first type light emitting diode of the light source unit, and Q, which is a current to be supplied to the second light emitting diode, can be obtained so that light corresponding to the desired illuminance Ln and the desired color temperature CTa can be provided by the light source unit.

As an alternative embodiment, the embodiment may further comprise one or more correction steps.

It is possible to proceed with the correction in consideration of the characteristics of the light source portion, so that the slope values of the straight lines and the slope of the straight line in Fig. 5 can be corrected.

In addition, it may include a calibration step through darkroom testing. In other words, the slope of the straight line and the slice values of each straight line in FIG. 5 can be corrected by reflecting the experiment data while supplying current to the first type light emitting diode and the second type light emitting diode of the light source part in the dark room condition.

In addition, as a correction step through an installation test, data that have been experimentally supplied while supplying current to the first type light emitting diode and the second type light emitting diode of the light source unit at the installation place where the light source unit installation step (S120) The slope of the straight line and the slice values of each straight line in Fig. 5 can be corrected.

As another example, at least one of the correction step through the dark room test and the correction step through the installation test can be performed.

As an alternative embodiment, after performing the correction step through the dark room test, the correction step through the installation test can proceed.

In the present embodiment, it has been described that the current information acquisition step (S140) is performed after the light source portion installation step (S120).

As an alternative embodiment, the current information acquisition step (S140) may be performed before proceeding to the light source installation step (S120).

Also, as an alternative embodiment, the light source unit installation step S120 and the current information acquisition step S140 may be performed at the same time, or some points of view may overlap.

In the current supply control step S150, current is supplied to the light source section in accordance with the current information acquired in the current information acquisition step S140. Specifically, the current is supplied to the first type light emitting diode of the light source section by the first type current and the second type light emitting diode And can supply the second type current.

That is, for example, the current of X value is supplied to the first type light emitting diode of the light source unit corresponding to the coordinates (X, Y) finally obtained in the graph of FIG. 6, and the current of Y value is supplied to the second light emitting diode Can supply.

Further, as an alternative embodiment, when the correction step of the plural steps is performed, the currents of the coordinates (X ", Y ") corresponding to the corrected values can be supplied to the first type light emitting diode and the second light emitting diode, respectively .

In addition, different currents can be easily supplied for each time zone to correspond to the reference information. That is, for example, currents of different values corresponding to light of respective illuminance and color temperature corresponding to sunrise, daylight and sunset can be supplied to the first type light emitting diode and the second light emitting diode, respectively, over time.

The lighting control method of the present embodiment may include a light source preparation step, and the light source unit may include a first type light emitting diode and a second type light emitting diode. The color temperature of the first type light emitting diode may be higher than the color temperature of the second type light emitting diode. For example, the first type light emitting diode may be a cool type light emitting diode and the second type light emitting diode may be a warm type ) Light-emitting diodes.

Thus, the characteristics of the light provided by the light source can be controlled variously. For example, light similar to natural light can be easily provided, and as another embodiment, light similar to natural light can be easily provided with light that is modified to meet desired conditions.

Further, it is possible to easily control the illumination in the work space in which the optical characteristic needs to be controlled sensitively through the control of such light. For example, it is possible to facilitate lighting control in a space for raising poultry where the rearing condition is sensitive to lighting, and the poultry rearing characteristics can be improved.

Particularly, in the present embodiment, reference information corresponding to illuminance and color temperature for each time period, such as illuminance and color temperature of natural light according to time, can be used.

The light current can be controlled so as to control light of the illuminance and color temperature corresponding to the reference information.

That is, information on each current to be supplied to each of the first type light emitting diode and the second type light emitting diode having different color temperatures of the light source unit can be obtained, and the information on the currents to be supplied to the first type light emitting diode and the second type light emitting diode The magnitude of the supplied current can be controlled by time zone.

Thus, light having desired illuminance and color temperature can be easily supplied to the work space from the light source unit. Particularly, a first type light emitting diode and a second type light emitting diode having different color temperatures, for example, a cool type and a worm type, can be mixed and controlled to easily realize high quality light similar to natural light.

Further, in this embodiment, a straight line-shaped isoelectric line can be defined. The currents of the plurality of first type light emitting diodes and the second type light emitting diodes, which realize the desired illuminance, can be obtained by the definition of these isoelectric leads by a first order, and by using the isoelectric wires corresponding to the desired illuminance sequentially, And the currents of the first type light emitting diode and the second type light emitting diode at a desired color temperature can be obtained through a calculation formula. As a result, the current of the first type light emitting diode and the current of the second type light emitting diode for light corresponding to the desired illuminance and color temperature can be obtained.

Accordingly, the characteristics of the light supplied from the light source unit, that is, the color temperature and the illuminance can be precisely controlled, and the light having desired optical characteristics can be easily provided.
