That is, the smartphone 6 stores the package dimming rate of each of the three color LEDs when the lighting fixture 4 emits light at a certain chromaticity. Further, the user can control the light emitting state by designating the dimming rate from 0% in the extinguished state to 100% in the fully lit state in the luminaire 4. The dimming rate specified by this user is hereinafter referred to as "designated dimming rate". When the lighting fixture 4 emits light at a certain chromaticity, the smartphone 6 controls to emit light at each LED package at a dimming rate obtained by multiplying each package dimming rate corresponding to the chromaticity by a specified dimming rate. Will be done. That is, even when the designated dimming rate is changed, the chromaticity when the luminaire 4 emits light does not change.

The smartphone 6 is provided with a GUI for designating a designated dimming rate and chromaticity desired by the user, and notifies the lighting fixture 4 of a control signal corresponding to the chromaticity and the designated dimming rate instructed by the user to illuminate the lighting fixture 4. The device 4 emits light according to the notified control signal.

<1.2.2. Group switching GUI120>
FIG. 4B shows a GUI 200 (see FIG. 8) of a normal specification for performing dimming and toning and a GUI 120 for calling a GUI 130 (see FIG. 5) of an effect specification for a group.

Here, the GUI of the normal specification is a GUI that causes the user to specify the chromaticity along the blackbody radiation locus when the user specifies the chromaticity related to the light emission of the lighting equipment. The production specification GUI is a GUI that allows the user to select not only the chromaticity along the blackbody radiation trajectory but also the chromaticity that does not follow when the user specifies the chromaticity related to the light emission of the lighting equipment. , It is provided with a plurality of color setting buttons that correspond to each of a plurality of chromaticities when the lighting fixture 4 emits light and emit light at the corresponding chromaticities when touched by the user, and each of the color setting buttons has a corresponding color. At least part of it is colored with a color that imitates the degree.

The GUI 120 includes a normal specification display panel 123 and an effect specification display panel 124. The normal specification display panel 123 transitions to display the normal specification GUI 200 (see FIG. 8) when touched by the user, and the effect specification display panel 124 displays the effect specification GUI 130 (see FIG. 8) when touched by the user.

The color temperature display unit 123c is a circular image, and the color represents the color temperature of the light emitted by the light source unit 40 according to the current setting.

<1.2.3. Directional specifications GUI130>
FIG. 5 is a diagram showing a GUI 130 of an effect specification for performing dimming and toning.

As shown in FIG. 5, the GUI 130 includes a color selection area 131, a switching unit 132, a dimming rate selection unit 135, a horizontal color selection unit 137, and a vertical color selection unit 139.

The color selection area 131 has a predetermined number (11 x 11 as an example) of circular color setting buttons 131a, 131b, 131c, 131d, ..., 131h ... (hereinafter, "color setting button") in a rectangular frame. 131X ") are arranged in a rectangular matrix.

It is desirable that the number of color setting buttons arranged in the color selection area 131 is limited to such that the number of choices that the user can select is not too small and the number of choices is too large to be confused as to which one should be selected. Therefore, it is desirable that the number of color setting buttons is 5 × 5 or more and 15 × 15 or less.

The color setting button 131X is associated with the chromaticity of light when the light source unit 40 of the lighting fixture 4 emits light. By touching the color setting button 131X, the user can make the light source unit 40 of the lighting fixture 4 emit light with the chromaticity associated with the color setting button 131X in advance.

The color setting button 131X is associated with a chromaticity when the light source unit 40 emits light, or more accurately, a control signal output to the light source unit 40 in order to emit light at that chromaticity. That is, each color setting button 131X is associated with a control signal corresponding to the current value supplied to each of the blue-white LED 42c, the red LED 42b, and the yellow-white LED 42a, and the correspondence table thereof is stored in the ROM 62.

When the touch panel 65 detects that the user has touched the color setting button 131X on the smartphone 6, the touched color setting button 131X is notified to the control unit 61. The control unit 61 refers to the correspondence table between the chromaticity corresponding to the button stored in the ROM 62 and the control signal, reads out the control signal corresponding to the touched color setting button 131X, and uses the wireless communication unit 64. , Is transmitted to the lighting fixture 4 to be controlled. The luminaire 4 that has received the control signal causes the light source unit 40 to emit light with a chromaticity corresponding to the control signal.

<Arrangement of color setting button 131X>
Here, the arrangement of each color setting button 131X in the rectangular matrix will be described. In the rectangular matrix of the color selection area 131, a color setting button 131a is arranged in the lower right corner, a color setting button 131b is arranged in the upper right corner, a color setting button 131c is arranged in the upper left corner, and a color setting button 131d is arranged in the lower left corner.

The color setting button 131a corresponds to the chromaticity coordinates of the light color when only the red LED 42b is turned on, and is associated with a control signal for turning on only the red LED 42b. When the user touches the color setting button 131a, the light source unit Only the red LED 42b in 40 is lit.

The color setting button 131b corresponds to the chromaticity coordinates of the light color when only the bluish white LED 42c is turned on, and is associated with the control signal for turning on only the bluish white LED 42c. Only the bluish white LED 42c in the light source 40 is lit.

The color setting button 131c corresponds to the chromaticity coordinates of the light color when only the yellow-white LED 42a is turned on, and is associated with a control signal for turning on only the yellow-white LED 42a. Only the yellow-white LED 42a in the light source 40 is lit.

The color setting button 131d corresponds to the chromaticity coordinate of the intermediate point between the chromaticity coordinate corresponding to the color setting button 131a and the chromaticity coordinate corresponding to the color setting button 131c, and the red LED 42b and the yellow-white LED 42a have the same adjustment. It is associated with a control signal that lights up at the chromaticity. When the user touches the color setting button 131d, the red LED 42b and the yellow-white LED 42a in the light source unit 40 are turned on at the same dimming rate.

As shown in FIG. 5, nine color setting buttons are arranged between adjacent color setting buttons located at the four corners of the rectangle in the color selection area 131. Among the color setting buttons located at the four corners of the rectangle in the color selection area 131, the color setting buttons (referred to as "first color setting button" and "second color setting button" for convenience) are adjacent to each other (for convenience, "first". The chromaticity associated with (referred to as "3 color setting button") is the chromaticity coordinate corresponding to the first color setting button and the color corresponding to the second color setting button on the chromaticity diagram shown in FIG. Corresponds to each chromaticity coordinate obtained by equally dividing a straight line connecting the degree coordinates (10 equal parts in this embodiment).

For example, as shown in FIG. 5, nine color setting buttons including the color setting button 131h are arranged between the color setting button 131a and the color setting button 131b. For each color setting button, in the chromaticity coordinates of FIG. 3, the chromaticity coordinates (0.60.0.38) of the red LED 42b corresponding to the color setting button 131a and the bluish white LED 42c corresponding to the color setting button 131b Corresponds to each point that divides the straight line connecting the chromaticity coordinates (0.23, 0.26) into 10 equal parts. The color setting button 131h corresponds to the chromaticity coordinates of the point closest to the chromaticity coordinates (0.60.0.38) among the nine points that divide the challenge connecting the chromaticity coordinates into 10 equal parts.

Here, in the chromaticity diagram, when the red LED 42b and the yellowish white LED 42a are turned on at the same dimming rate, the chromaticity near the chromaticity coordinates of the chromaticity is easy for the user to recognize the difference. Therefore, by associating the chromaticity when the red LED 42b and the yellowish white LED 42a are turned on at the same dimming rate with the color setting button 131d, a plurality of chromaticities in the vicinity of the chromaticity coordinates where the user can easily recognize the difference can be obtained. In the color selection area 131, detailed choices can be provided. Therefore, the GUI 130 is a user interface that makes it easy for the user to select a desired chromaticity.

The setting of the color setting button 131d does not necessarily correspond to the chromaticity when the red LED 42b and the yellow-white LED 42a are turned on at the same dimming rate. For example, when the light source unit 40 of the lighting fixture 4 includes LED packages of four different colors instead of three colors as described above, the chromaticity when any one of the four colors of the LED package emits light. More precisely, each of the four color LED packages corresponds to the control signal output to the light source unit 40 in order to emit light at that chromaticity, and each of the four color LED packages has the color setting buttons at the four corners in the rectangular matrix of the color selection area 131. It may correspond to.

Further, when the light source unit 40 includes a plurality of LED packages, each of the LED packages of each color may be associated with any of the color setting buttons in the rectangular matrix of the color selection area 131.

Similarly, when the first color setting button and the second color setting button are not located at the four corners, they are located between the first color setting button and the second color setting button, and the first color setting button is located. The chromaticity of the K (K is any of 1 to 9) th color setting button counted from is the chromaticity coordinate on the chromaticity diagram of the chromaticity of the first color setting button and the second color setting. When the chromaticity coordinates on the chromaticity diagram of the buttons are connected by a straight line and divided equally by the number of color setting buttons located between the first color setting button and the second color setting button + 1. Of the chromaticity coordinates, it corresponds to the Kth chromaticity coordinate counted from the chromaticity coordinate of the first color setting button.

Each color setting button 131X is filled with an image color that the user can intuitively grasp the light color emitted by the light source unit 40 when the color setting button 131X is touched.

FIG. 6 shows the colors of the image of the color setting button 131X in the rectangular matrix of the color selection area 131 in RGB format. RGB values are associated with each of the color setting buttons 131X. In FIG. 6, Gm (m is 0 to 10) indicates the number of color setting buttons in the horizontal direction with respect to the color setting button 131c in the upper left corner of the matrix, and Pn (n is 0 to 10) is the matrix. Indicates the number of color setting buttons in the vertical direction with respect to the color setting button 131c in the upper left corner of. For example, the color setting button 131h corresponds to the intersecting columns of G10 and P9, where R is 255, G is 57, and B is 40.

Note that ... in FIG. 6 actually has numerical values in the columns of G2 to G8, the rows of P2 to P8, and some of the rows of P1 and P9, but they are omitted in FIG. Represents that.
