<Control command input example>

Since the control device 200 is a wearable device worn on the wrist, the user can move a hand wearing the control device 200 to input a predefined control command.

Herein, an example of command input using the movement of the hand according to the present invention will be described with reference to FIG. 2 and FIG.

FIG. 2 illustrates the definition of the LED on / off signal, control mode entry signal, and control mode exit signal according to the present invention based on the XZ axis circular motion operation. The XZ-axis circular rotation operation is an operation to rotate the wrist clockwise or counterclockwise in the X-axis and Z-axis directions with reference to the control device 200, The operation corresponding to the OFF signal (LED off operation), the operation corresponding to the entry into the control mode (the entering operation into the control mode), and the operation corresponding to the control mode exit (the control mode exit operation).

By applying this algorithm, it is possible to perform a specific control value change by a combination of the X-axis, the Y-axis, and the Z-axis.

<Configuration of medical light control method>

A control method applicable to the medical lighting control system according to the first preferred embodiment of the present invention will be described with reference to FIG.

When the three-axis acceleration sensing value indicating the LED on operation by the user is inputted (step 300), the control device 200 generates and provides the LED on signal to the illumination device 100 (step 302).

When the LED-on signal is provided from the control device 200, the illumination device 100 turns on the LED lamp 110 and generates a BEEP sound in steps 400 and 402.

If the LED off signal is provided while the illumination light 110 is turned on, the illumination device 100 turns off the illumination light 110 as an LED and generates a BEEP sound in steps 404 and 406.

Alternatively, if the LED-on signal is provided to the illumination device 100 and the three-axis acceleration sensing value indicating the entering operation into the control mode by the user is input in step 308, And generates an entrance signal and provides it to the lighting apparatus 100 (step 310).

Here, the specific control value may be a roughness change, a color temperature change, a pattern size, an irradiation angle change, or the like.

The control device 200 controls the operation of the control device 200 such that the user performs an axial operation, that is, a + X axis setting operation or a -X axis setting operation, a + Y axis setting operation, a -Y axis setting operation, A setting operation, and a -Z axis setting operation (step 312).

The specific control value includes a roughness change, a color temperature change, a pattern size change, an irradiation angle change, and the like. The movement of the user for each control value is previously set and stored as illustrated in FIG.

When the specific control value is received from the control device 200, the illumination device 100 performs a control operation corresponding thereto. That is, according to the specific control value, the illumination apparatus 100 outputs a BEEP sound for performing illumination change, color temperature change, pattern size change, irradiation angle change, and the like to perform a control operation according to the specific control value 412, 414, 416).

However, if the user does not perform the axial operation, the control device 200 enters the step 304 and checks whether the user instructs the LED off.

On the other hand, after transmitting the specific control value as described above, if the user does not perform the axial movement, the control device 200 checks whether the user moves in more than one direction of the X, Y, or Z axis (Step 316). If the user moves more than the set value to one or more directions, the wait count is reset (step 318). Then, the process goes back to step 316 to repeat the process of generating and transmitting the specific control value.

Otherwise, the control device 200 increases the wait count (step 322). If the wait count is not less than the preset value (step 324) (Step 320), and then transmits the control mode exit signal to the lighting apparatus 100 (step 326). The control mode exit signal indicates that the user shakes the hand for a predetermined period of time.

When the control mode exit signal is received from the control device 200 in step 418, the illumination device 100 outputs a BEEP sound for ending waiting for reception of the specific control value and for guiding the control mode exit (Step 420).
