Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

1 shows a schematic configuration of a lighting system according to an embodiment of the present invention.

1, an illumination system according to an embodiment of the present invention includes a light control device 100 that adjusts the brightness level of a light 20 (e.g., OLED) in response to a rotation operation of an encoder knob 10, As shown in FIG.

The illumination control apparatus 100 according to an embodiment of the present invention can control not only the rotation operation of the encoder knob 10 but also the brightness of the illumination 20 according to a touch signal received from the touch sensor 30 Do.

As described above, the brightness adjustment of the illumination 20 according to the touch signal received from the touch sensor 30 can be performed not only by turning on / off the illumination 20, It is also possible to adjust the step.

For example, when a short (e.g., less than one second) touch signal is input when the illumination 20 is in an Off state, the illumination 20 is turned on in a minimum brightness step (e.g., step 1) Up to a maximum brightness level (e.g., 4th to 5th steps) every time the touch signal is received.

If another touch signal is received at the maximum brightness level, the illumination 20 is adjusted down to the minimum brightness level. At each brightness level, a long (e.g., about 1 second to 2) If it is received, the illumination 20 can be switched off.

Meanwhile, in the illumination control apparatus 100 according to the embodiment of the present invention, as described above, the dimming function for finely adjusting the brightness of the illumination 20 according to the rotation operation of the encoder knob 10 is supported.

Here, the encoder knob 10 refers to a rotary encoder, which generates twenty-four pulse signals when the knob rotates infinitely, for example, 360 degrees in both directions, As shown in FIG.

For example, if the brightness level of the illumination 20 is set to 256 levels, the brightness level of the illumination 20 may be increased by one level using the pulse signal of one period generated during the operation of rotating the encoder knob 10 by 15 degrees. It becomes possible to adjust the up / down direction.

The brightness level (e.g., 256 levels) of the light 20 that can be adjusted by the rotation operation of the encoder knob 10 is determined by the brightness level of the light 20 that is adjusted through the aforementioned touch sensor 30 For example, step 5) and as shown in Table 1 below.

Operating means Touch sensor Encoder knob Matching step Stage 1 Step 51 Step 2 Step 102 ... ... Step 5 Step 255

For reference, the brightness level (e.g., 256 steps) of the light 20 that can be adjusted by the rotary operation of the encoder knob 10 and the brightness level of the light 20 that is adjusted through the touch sensor 30 5) is matched, in one embodiment of the present invention, it becomes possible to quickly operate the illumination 20 to a desired brightness through a combination of the turning operation of the encoder knob 10 and the touch operation of the touch sensor 30 .

For example, if it is desired to adjust the brightness of the illumination 20 to 75%, the encoder knob 10 is rotated 112 ° in the forward direction (or reverse direction) after touching the touch sensor 30 three times in succession, 30) is continuously rotated four times and then the encoder knob 10 is rotated in the reverse direction (or forward direction) by 35.5 °.

As such, it can be seen that the brightness level adjustment of the illumination 20 through the rotary operation of the encoder knob 10 is finer than the brightness level adjustment of the illumination 20 via the touch sensor 30. [

However, while adjusting the brightness level of the illumination 20 through the rotary operation of the encoder knob 10 has the advantage of being capable of fine adjustment, it is advantageous to adjust the brightness of the illumination 20 from the minimum brightness level (e.g., 0 level) There is a problem of excessive rotation operation in which the encoder knob 10 needs to be rotated 10.6 times in order to adjust up to 256 steps.

Accordingly, in an embodiment of the present invention, a new method for solving the problem of the excessive rotation operation of the encoder knob 10 is proposed. Hereinafter, the configuration of the illumination control apparatus 100 will be described in more detail I will explain.

2 shows a schematic configuration of a lighting control apparatus 100 according to an embodiment of the present invention

2, a lighting control apparatus 100 according to an embodiment of the present invention includes a processing section 110 for processing brightness level adjustment of the illumination 20 according to a predefined control value, and an encoder knob And an update unit (120) for updating the control value based on the rotation speed of the rotation shaft (10).

All or at least a part of the configuration of the illumination control apparatus 100 including the processing unit 110 and the updating unit 120 may be implemented in a form of a hardware module or a software module or a combination of a hardware module and a software module Can be implemented.

Here, the software module may be understood as an instruction executed by a processor that processes an operation in the illumination control apparatus 100, and such an instruction may have a form stored in the illumination control apparatus 100. [

The illumination control apparatus 100 according to the embodiment of the present invention adjusts the brightness level from the minimum brightness level to the maximum brightness level of the illumination 20 according to the rotation speed of the encoder knob 20, Hereinafter, each configuration of the illumination control apparatus 100 for this purpose will be described in detail.

According to an embodiment of the present invention, the first pulse signal and the second pulse signal having the same pulse width as the first pulse signal are generated according to the rotation operation of the encoder knob 10, and the first pulse signal and the second pulse signal The description will be continued on the assumption that the pulse signal has a delay of 1/2 pulse width with respect to each other due to the structural characteristics of the encoder knob 10.

The processing unit 110 performs processing of adjusting the brightness level of the illumination 20 according to a predefined control value.

More specifically, when the first pulse signal and the second pulse signal are generated according to the rotation operation of the encoder knob 10, the processing unit 110 generates an interrupt generation period And the brightness level of the illumination 20 is adjusted according to the pulse value of the second pulse signal at the time of the interruption.

In the case of the control value referenced in the processing unit 110, as shown in FIG. 3, each of the rising edge periods a and b of the first pulse signal is designated as an interrupt occurrence period, When the pulse value of the second pulse signal at the time point is '0', the brightness level of the illumination 20 may be defined to be adjusted up by a first adjustment number (for example, one level).

On the contrary, when the pulse value of the second pulse signal at the interrupt occurrence time is '1', the brightness step of the illumination 20 is set to the first Of course, be adjusted upwards by an adjustment number (e.g., one step).

On the other hand, when the pulse value of the second pulse signal at the time of interruption is '1', it can be understood that the brightness level of the illumination 20 is adjusted downward by a first adjustment number (for example, one level).

The update unit 120 performs a function of updating the control value based on the rotation speed of the encoder knob 10. [

More specifically, the update unit 120 confirms the rotation speed of the encoder knob 10 when the adjustment of the brightness level of the illumination 20 is started according to the occurrence of the interruption according to the rotation operation of the encoder knob 10, The control section 100 updates the control value referenced in the processing section 110 according to the detected rotation speed of the encoder knob 10 so that the pulse interval designated as the interrupt generation interval and the number of the brightness stages adjusted at the interrupt generation time So that at least one can be varied.

At this time, the confirmation of the rotation speed of the encoder knob 10 is performed by a method of confirming the pulse widths (a, b) from the time when the interrupt occurs to the neighboring rising edge section or the falling edge section as shown in FIG. Lt; / RTI >

Here, each of the pulse widths (a, b) from the time when the interruption occurs to the neighboring rising edge section or the falling edge section becomes shorter as the rotation speed of the encoder knob 10 increases, The length of the pulse width can be interpreted as the rotation speed of the encoder knob 10.

Hereinafter, a description will be given of updating the control value based on the rotation speed of the encoder knob 10, which is confirmed using the pulse width from the time when the interrupt occurs to the neighboring rising edge section or the falling edge section do.

First, the updating unit 120 determines whether the rotation speed of the encoder knob 10 exceeds the first reference speed (e.g., 15 ms) (fast) and the second reference speed 14 ms (slow) Both the rising edge interval and the falling edge interval of the first pulse signal are designated as the interrupt occurrence interval and the control value can be updated such that the brightness level at the interrupt occurrence time is adjusted by the first adjustment number (one step).

The fact that both the rising edge interval and the falling edge interval of the first pulse signal are designated as the interrupt occurrence interval means that the occurrence frequency of the interrupt is one period shorter than the case where only the rising edge interval of the first pulse signal is designated as the interrupt occurrence interval The rising edge period of the first pulse signal is designated as the interrupt occurrence period even if the control value is updated so that the brightness level at the time of the interrupt occurrence is adjusted by the first adjustment number (one level) The number of brightness steps to be controlled can be doubled.

That is, referring to the previous example in which the encoder knob 10 must be rotated 10.6 times in order to adjust the brightness level of the illumination 20 from the minimum brightness level (e.g., 0 level) to the maximum brightness level (e.g. 256 levels) If both the rising edge interval and the falling edge interval of the first pulse signal are designated as the interrupt occurrence interval, the brightness level of the illumination 20 is adjusted to the minimum brightness level (for example, 0 level) by rotating the encoder knob 10 by 5.3 times ) To a maximum brightness level (e.g., 256 levels).

When the control value is updated so that both the rising edge period and the falling edge period of the first pulse signal are designated as the interrupt occurrence period, the pulse value of the second pulse signal in the rising edge period of the first pulse signal is' 0 ', the brightness level of the illumination 20 is adjusted upward. On the other hand, when the pulse value of the second pulse signal is' 1' in the falling edge period of the first pulse signal, Upwards adjustment will have to be done.

When the rotation speed of the encoder knob 10 exceeds the second reference speed (14 ms), the updating unit 120 updates both the rising edge interval and the falling edge interval of the first pulse signal as shown in FIG. 5 Is set as the interrupt occurrence period and the brightness level controlled at the time of occurrence of the interrupt does not exceed the second control number (e.g., five steps) greater than the first control number (e.g., one level) 10, the control value can be updated to be adjusted to a larger number.

The fact that the brightness level adjusted at the time of interrupt generation is adjusted to a larger number as the rotation speed of the encoder knob 10 is increased means that the number of brightness levels that can be adjusted at the time of one interruption is controlled by the encoder knob 10, The speed of the light 20 can be adjusted by rotating the encoder knob 10 by, for example, about one turn at a time, without performing any number of rotation operations, It becomes possible to adjust the step from the minimum brightness level (e.g., 0 level) to the maximum brightness level (e.g. 256 levels).

Updating the control value to be adjusted to a larger number as the rotation speed of the encoder knob 10 is faster as long as the second adjustment number (for example, five steps) is not exceeded, And the second adjustment number (for example, five steps) may be defined as various numbers depending on the setting.

Meanwhile, the update unit 120 records the rotation speed of the encoder knob 10, which has been checked after the occurrence of each interrupt, through the update unit 120. The rotation speed of the encoder knob 10, which is checked according to the occurrence of a new interrupt, It is possible to compare the rotation speed of the encoder knob 10 confirmed in the previous step and to maintain the previous control value if there is no difference.

As described above, according to the configuration of the lighting control apparatus 100 according to the embodiment of the present invention, the brightness level from the minimum brightness level to the maximum brightness level of the illumination 20 according to the rotation speed of the encoder knob 10 The problem of excessive rotation of the encoder knob 10 is solved in adjusting the brightness of the illumination 20 from the minimum brightness to the maximum brightness so that the user convenience can be improved .

The operation of the illumination control apparatus 100 according to an embodiment of the present invention will now be described with reference to FIG. 6. FIG.

First, when the first pulse signal and the second pulse signal are generated according to the rotation operation of the encoder knob 10, the processing unit 110 generates a control signal based on the predefined control value according to steps 'S110' to 'S130' 1 pulse signal is designated so that the brightness level of the illumination 20 is adjusted in accordance with the pulse value of the second pulse signal at the time of the interruption.

At this time, in the case of the control value referenced by the processor 110, the rising edge of the first pulse signal is basically designated as the interrupt occurrence period, the pulse value of the second pulse signal at the interrupt occurrence time is' , It may be defined to adjust the brightness level of the illumination 20 by a first adjustment number (e.g., one level).

On the contrary, when the pulse value of the second pulse signal at the interrupt occurrence time is '1', the brightness step of the illumination 20 is set to the first Of course, be adjusted upwards by an adjustment number (e.g., one step).

On the other hand, when the pulse value of the second pulse signal at the time of interruption is '1', it can be understood that the brightness level of the illumination 20 is adjusted downward by a first adjustment number (for example, one level).

The update unit 120 updates the rotation speed of the encoder knob 10 according to step S140 when the adjustment of the brightness level of the illumination 20 is started according to the occurrence of the interruption according to the rotation operation of the encoder knob 10, So that the control value referred to in the processing unit 110 can be updated according to the rotation speed of the detected encoder knob 10. [

At this time, the confirmation of the rotation speed of the encoder knob 10 can be performed by a method of checking the pulse widths (a, b) from the time when the interrupt occurs to the neighboring rising edge interval or the falling edge interval.

Here, the pulse width from the point of time when the interruption occurs to the neighboring rising edge section or the falling edge section becomes shorter as the rotation speed of the encoder knob 10 becomes faster. Therefore, the length of such a pulse width is It can be interpreted as the rotation speed of the encoder knob 10.

Then, the update unit 120 updates the rotation speed of the encoder knob 10 to a first reference speed (e.g., 15 ms) (fast) and a second reference speed (14 ms ), It is determined that both the rising edge interval and the falling edge interval of the first pulse signal are designated as the interrupt generation interval according to step S180, and the brightness level of the interrupt generation time is set to the first adjustment number ( One step).

If the rotation speed of the encoder knob 10 is found to exceed the second reference speed (14 ms) in the previous step 'S170', the updating unit 120 updates the rising Both the edge interval and the falling edge interval are designated as the interrupt occurrence interval and the brightness level adjusted at the time of occurrence of the interrupt does not exceed the second adjustment number (e.g., five steps) larger than the first adjustment number The control value is updated so that the rotation speed of the encoder knob 10 is adjusted to a larger number.

The fact that the brightness level adjusted at the time of interrupt generation is adjusted to a larger number as the rotation speed of the encoder knob 10 is increased means that the number of brightness levels that can be adjusted at the time of one interruption is controlled by the encoder knob 10, The speed of the light 20 can be adjusted by rotating the encoder knob 10 by, for example, about one turn at a time, without performing any number of rotation operations, It becomes possible to adjust the step from the minimum brightness level (e.g., 0 level) to the maximum brightness level (e.g. 256 levels).

Updating the control value to be adjusted to a larger number as the rotation speed of the encoder knob 10 is faster as long as the second adjustment number (for example, five steps) is not exceeded, And the second adjustment number (for example, five steps) may be defined as various numbers depending on the setting.

When the control value is updated such that both the rising edge period and the falling edge period of the first pulse signal are designated as the interrupt occurrence period as in steps S180 and S190, If the pulse value of the second pulse signal of the first pulse signal is '0', the brightness of the illumination 20 is adjusted upward. On the contrary, if the pulse value of the second pulse signal is '1' The upward adjustment of the brightness level of the illumination 20 will have to be performed.

If it is determined that the rotation speed of the encoder knob 10 is equal to or less than the first reference speed (for example, 15 ms) in step S150, the update unit 120 updates the basic control value referred to in step S110 Of course, be maintained.

As described above, according to the operation flow of the lighting control apparatus 100 according to the embodiment of the present invention, the brightness of the illumination 20 can be changed from the minimum brightness level to the maximum brightness level according to the rotation speed of the encoder knob 10. [ By adjusting the brightness level adaptively, the problem of excessive manipulation of the encoder knob 10 is solved in adjusting the brightness of the illumination 20 from the minimum brightness to the maximum brightness, have.
