Description

The present invention relates to a control method of a lighting device using an LED, and more particularly to a control method of controlling a lower limit value of a voltage applied to a lighting device operated by a touch panel.

Due to the growing environmental awareness in recent years, lighting devices using LEDs with low power consumption and high durability are widely used regardless of whether they are for home use or business use (for example, Patent Documents 1 to 3).
Further, as a switch for operating this, in addition to the conventional mechanical type, a touch panel type switch that can control not only the turning on and off but also the illuminance from turning off to all lights is being adopted.
Compared to mechanical switches, touch panel switches have no protrusions, require less acupressure, and have the potential to become more widespread in the future due to their design advantages.

By the way, as shown in FIG. 8, when a lighting device using an LED is in a lighting state, it is perceived as being constantly lit by repeating blinking at a speed that cannot be perceived by a person.
When the voltage applied to the lighting device is low, as shown in FIG. 9, a state in which the blinking cycle is perceived by a person and a person can perceive the extinguished state, that is, a so-called "flicker phenomenon" occurs.
Since the lower limit of the voltage at which this flicker phenomenon occurs differs depending on each LED, the user needs to adjust the voltage within a range where the flicker phenomenon does not occur while checking the state of light emission.

This work is usually complicated for the user, and since the lighting device for home use is used by various people including children, a method capable of easily adjusting the voltage applied to the lighting device is required.
Conventionally, this voltage adjustment has been performed by opening a switch on the wall or a lighting unit provided on the ceiling and operating the board inside.

The present invention has been developed in response to the above-mentioned problems. That is, an object of the present invention is to provide a control method capable of easily excluding a range in which a flicker phenomenon occurs when a user adjusts a lighting device using an LED.

After that, in response to the long press operation, the control unit cancels the lower limit value setting, and the control unit displays that the lower limit value has been set or the control unit has released the lower limit value in a part of the panel unit. The control method is characterized in that the LED lighting unit to which a voltage that does not cause the flicker phenomenon of the LED lighting unit is applied is lit in a range of 50 Hz or more.

You can set the value.
Further, since the control is performed by the three operations of the short press operation, the long press operation and the slide operation by the operator, the user can easily set the lower limit value.

FIG. 1 is a schematic view of an LED lighting device L that carries out the control method of the present invention.
The LED lighting device L using the control method of the present invention is a ceiling lighting mainly used indoors.
The LED lighting device L includes a panel unit 1 and an LED lighting unit 2, and an LED light bulb is attached to the LED lighting unit 2 provided on the indoor ceiling.
Further, the panel unit 1 includes an operation unit 11 and a control unit 12.

As the panel unit 1 for controlling the LED lighting device L, for example, a capacitive touch panel is adopted here, and the panel unit 1 is attached to the wall surface of the room where the LED lighting device L is installed.
In particular, since the touch panel is of the capacitance type, the detection accuracy is high and false detection can be reliably prevented.
The operation unit 11 is arranged on the front surface of the panel unit 1 so as to easily accept the user's operation.
Further, the operation unit 11 is divided into regions of the upper portion 11a, the central portion 11b, and the lower portion 11c, and the long press operation B described later is input in the region of the central portion 11b or the lower portion 11c, and the short press operation A is performed. Each of these is performed in three areas.
Further, the slide operation C is performed over two regions of the upper portion 11a and the central portion 11b or the central portion 11b and the lower portion 11c, or over these three regions.
In the center of the operation unit 11, a display unit 11d for displaying the operation status of the panel by light emission is provided.

FIG. 2 is an explanatory diagram showing an outline of the LED lighting device.
A control unit 12 made of a circuit board is provided on the back surface of the panel unit 1, detects an operation on the operation unit 11, and changes the voltage applied to the LED lighting unit 2 according to the operation.
That is, the voltage for the LED lighting unit 2 is changed according to the detection signal from the operation unit 11.
The control unit 12 assigns the LED lighting unit 2 to the LED lighting unit 2 according to the detection unit 12A that detects each operation performed by the operation unit 11 and the operation mode detected by the detection unit 12A. It includes a voltage adjusting unit 12B that changes the voltage.
In the LED lighting unit 2, the lighting state and the extinguishing state are switched, and the illuminance in the lighting state is increased or decreased according to the voltage applied by the voltage adjusting unit 12B.

The operation unit 11 and the detection unit 12A of the control unit 12, the voltage adjustment unit 12B, and the LED lighting unit 2 are electrically connected to each other, and the detection signal of each operation described later performed by the operation unit 11 is transmitted by the detection unit 12A. When it is detected, the voltage adjustment signal from the detection unit 12A is transmitted to the voltage adjustment unit 12B, and the voltage adjustment unit 12B changes the voltage applied to the LED lighting unit 2.
The detection unit 12A corresponds to each of the upper portion 11a, the central portion 11b, and the lower portion 11c of the operation unit 11, and can detect in which region the operation is performed.

FIG. 3 is an explanatory diagram showing a specific operation for the panel unit 1.
(A) indicates a short press operation A, (b) indicates a long press operation B, and (c) indicates a slide operation C.
These operations are collectively called each operation.
The LED lighting device L can be lit and dimmed by the user performing a short press operation A, a long press operation B, and a slide operation C on the panel portion 1 with a fingertip or the like.
Here, the short press operation A is an operation of touching the panel portion 1 for an arbitrary fixed time or less, for example, 1 second or less, and then releasing the panel portion 1.
The long press operation B is an operation of touching the panel portion 1 for an arbitrary fixed time or longer, for example, 2 seconds or longer, and then releasing the panel portion 1.
The slide operation C is an operation of touching the panel portion 1, moving the fingertip in the vertical direction while maintaining the contact, and then releasing the slide operation C.

When the LED lighting unit 2 is in the off state, the LED lighting unit 2 is turned on by a short press operation A on the upper portion 11a, the central portion 11b or the lower portion 11c of the operation unit 11, and conversely, when the LED lighting unit 2 is in the lighting state, the operation unit 11 The light can be turned off by a short press operation A on the upper portion 11a, the central portion 11b, or the lower portion 11c.
Further, when the LED lighting unit 2 is in the lighting state, the LED lighting unit 2 can be dimmed by the slide operation C with respect to the upper portion 11a, the central portion 11b, or the lower portion 11c of the operation unit 11.
Dimming is performed by increasing or decreasing the voltage applied to the LED lighting unit 2.
Specifically, when the slide operation C is performed upward with respect to the panel unit 1, the voltage applied to the LED lighting unit 2 of the LED lighting device L increases, and as a result, the illuminance of the LED lighting unit 2 increases, and the illuminance of the LED lighting unit 2 increases. When the slide operation C is performed, the voltage decreases, and as a result, the illuminance decreases.
The specific circuit for performing these operations will be omitted.

As described above, in the LED lighting device L, the light from the LED lighting unit 2 blinks in a lit state at a cycle that is not recognized by humans.
At this time, if the voltage applied to the LED lighting unit 2 is too small, the blinking cycle becomes so large that the human eye can see it, as shown in FIG. 9, and a so-called “flicker phenomenon” occurs.
In order to prevent this, if the voltage applied to the LED lighting device L is increased, the blinking cycle becomes shorter. Therefore, it is necessary to set the lower limit value of the voltage applied to the LED lighting device L in the lit state in advance.
Since this lower limit value differs depending on the type of LED bulb used and the like, it is necessary to set it while checking the lighting state.

Hereinafter, the control method of the present invention will be described.
FIG. 4 is a flowchart of the control method of the present invention.
Now, it is assumed that the LED lighting unit 2 is in the off state.
First, the LED lighting unit 2 is turned on by a short press operation A on the panel unit 1.
Next, by performing the slide operation C on the panel unit 1 while checking the light of the LED lighting unit 2 in the lit state, the light is adjusted to the limit where the "flicker phenomenon" does not occur.
In this state, by performing the long press operation B on the lower portion 11C of the panel portion 1, the voltage limit at which the "flicker phenomenon" does not occur is set.
Normally, when the blinking of the light of the LED lighting unit 2 is 50 Hz or more (inversely proportional to the period), the flicker phenomenon does not occur.
In this way, the minimum voltage (that is, the lower limit) at which the "flicker phenomenon" does not occur is set.
When the lower limit value is set, the display unit 11d of the panel unit 1 emits light for a certain period of time, and the user is informed that the lower limit value has been set.

FIG. 5 is a flowchart when the LED lighting unit 2 is turned off.
Regardless of whether or not the lower limit value is set, in order to turn off the LED lighting unit 2 of the LED lighting device L when the LED lighting unit 2 is in the lighting state, a short press operation A is performed on the panel unit 1.
As a result, the control unit 12 turns off the LED lighting unit 2.

FIG. 6 is an explanatory diagram showing a voltage applied to the LED lighting unit 2.
X is an upper limit value of the voltage (V) applied to the LED lighting unit.
Y indicates the lower limit value of the voltage (V) when the lower limit value is set.
The vertical arrow on the left side indicates the fluctuation range V1 of the voltage applied to the LED lighting unit 2 in the lighting state when the lower limit value is not set.
The vertical arrow on the right side indicates the fluctuation range V2 of the voltage applied to the LED lighting unit 2 in the lighting state when the lower limit value is set.

As shown by the arrow in the vertical direction on the right side, once the lower limit value is set, the LED lighting unit 2 is turned off once, and even if it is turned on again, in the subsequent dimming, even if the slide control in the lighting state is performed. It is set so that a voltage lower than the lower limit value set above is not applied to the LED lighting unit 2.
As a result, the illuminance of the LED lighting unit 2 in the lit state becomes equal to or higher than a certain level, and the occurrence of the "flicker phenomenon" can be prevented.
Here, when the applied voltage is equal to or lower than the so-called barrier voltage, the lighting using the LED does not emit light without the movement of electrons. The lower limit is naturally set to a value higher than the barrier voltage.

FIG. 7 is a flowchart for canceling the setting of the lower limit value.
A case of canceling the set lower limit value setting, that is, a case of setting the lower limit value of the voltage applied to the LED lighting unit 2 in the lit state before setting the lower limit value (0V or more) will be described.
First, the lower limit value is set as described above, and the LED lighting unit 2 in the state where the lower limit value of the voltage is set is set to the lighting state.
Next, when the long press operation B is performed on the central portion 11b of the panel portion 1, the setting of the lower limit value is released.
At this time, the display unit 11d of the panel unit 1 emits light for a certain period of time, and the user is informed that the lower limit value has been set.

When setting the lower limit value, the emission color of the display unit 11d when the lower limit value of the illuminance is set and when the set lower limit value is released are different, so that the user can easily see the advantage. be.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.
The panel portion 1 is not limited to the capacitance method, and various types such as a resistance film method can be adopted.
The LED lighting device L is not limited to indoors, and may be used outdoors.
Further, the position where the panel portion 1 is provided is not limited to the wall, and may be portable.

Further, the slide direction in the slide operation C can be set to any direction such as left and right as well as up and down.
The short press operation A, the long press operation B, and the slide operation C for the panel unit 1 can be set to appropriate operation modes such as pinch-in or pinch-out operations.

It is also possible to use voice notification instead of the method of notifying the setting and cancellation of the lower limit value by the light emission of the display unit 11d.
In this case, the notification voice can be generated by providing the control unit with a voice generator.

In the control method of the present invention, the lower limit of the voltage at which the flicker phenomenon does not occur can be set while checking the light emitting state of the LED lighting unit. Therefore, the LED lighting device L controlled by the panel unit 1 regardless of the installation location. Can be widely used in.
